mitigating VMware migration risks

Many VMware customers are concerned about ever-increasing licensing costs, and are actively considering VMware alternatives. However, mitigating VMware migration risks is an even more significant concern. There are four steps that IT planners can take to ensure a seamless and risk-free migration to a new infrastructure platform:

  1. Upfront Assessment
  2. Virtual Proof of Concept
  3. On-Premises Evaluation
  4. Gradual Cut Over

Upfront Assessment of a VMware Alternative

Before diving deep into any IT project, you want to ensure the result will be significantly better than the current state. When considering a VMware alternative, reducing and simplifying licensing costs is one of the obvious areas to examine. Beyond licensing costs, IT should also evaluate long-term cost savings potential like:

Additionally, moving to an alternative platform should deliver more than cost savings. IT planners should consider the move to a new platform as an opportunity to improve capabilities like:

Finally, before moving to the next step, you should talk to some existing customers and see what they have to say about the potential alternative. Get their feedback on how easy the product is to use, how well it’s supported, and learn about their day-to-day experiences. Current customers can prove vendor claims.

Virtual Proof of Concept of a VMware Alternative

Once IT completes its initial assessment, most vendors try to rush to a proof of concept (POC). POCs are the cornerstone of mitigating VMware migration risks, but the problem is that a POC requires IT to find some hardware or make space for the vendor’s hardware. It also means that IT must find the time to go through the testing process and have a strategy for performing that test.

mitigating VMware migration risks

An alternative is a virtual proof of concept, where the vendor creates a virtual environment for you to test drive their solution. However, this virtual environment must give you full reign to perform whatever type of testing you want. You should be able to do more than “just drive the GUI.” You should be able to load up your virtual machines (VMs), test data protection capabilities, and start to think through on-premises test plans.

Your virtual instance should be 100% isolated from any other virtual POCs. Otherwise, you can’t deploy your applications and data without the risk of another organization gaining access to them. If the vendor can only deliver that isolation by dedicating specific hardware for the test, they will likely have to limit the time you can test. If the vendor can deliver that isolation, then they should be able to provide a very flexible testing timeframe.

On-Premises Evaluation of a VMware Alternative

If the potential VMware alternative still interests you after completing the virtual proof of concept, it is then time to move to an on-premises evaluation of the solution. Most vendors are happy to provide an on-premises evaluation. Still, the IT planner must pay attention to the vendor’s behavior as you move through this process.

There are red flags that will appear, even before you start testing. These red flags should give you some insight into how well the solution is going to perform for you in the coming years:

? Does the vendor require a multi-hour meeting to ensure all the technical requirements are met?
? Does the vendor insist on providing you with hardware even though they say they are "software-only"?
? Does the vendor want to come on-site to install the evaluation?
? Does the vendor push you to do a "try-and-buy" where you commit to buying the solution if critical requirements are met?
? Does the vendor insist you use the local technical resource for any technical questions that might arise?

An on-premises evaluation should be a strings-free relationship. You should be able to use existing hardware. It should only require a quick call, not a three-hour workshop, to ensure the hardware you plan to use is optimal for your testing. If the vendor claims to be software-only, then as long as you can provide hardware that meets their minimum requirements, you should be given the green light for your evaluation.

Usually, having a vendor come on-site to install an evaluation, or worse, providing you with a “turnkey” hardware package for the evaluation is a sign that the vendor is trying to hide how complex their solution is to get running. If it is hard to install, it will be hard to operate.

You are testing something new, and you will run into technical questions. You should go through regular technical support channels to get those questions answered. This process lets you see what kind of support you will get years after installation.

Gradual Cut-Over to the New Platform

Once you’ve completed the evaluation, you should map out a migration strategy before you commit to purchase. Mitigating VMware migration risks requires that the cut-over to the new platform is gradual. In most cases, you won’t flip a switch and, in a single pass, move all your VMs to the new platform. You typically migrate in “lumps,” one workload at a time. This more gradual process means the migration capabilities, if there are any, should be continuous. The new platform’s migration capabilities need to keep VMs from the VMware environment in sync so that the most recent copy of data is on the new platform when IT is ready to convert the next workload.

A near-continuous sync of VMware VMs to the new platform also means that it can provide enterprise-wide value from day one while you are gradually migrating to it. Suppose the migration function is near-continuous and intelligent enough only to move changed data blocks. In that case, it can act as a disaster recovery solution (DR) for the entire VMware environment. The result is from day one; it can save you money while you migrate at your pace. Without it, you are under too much pressure to show value from the new purchase quickly, making you more likely to rush VM migrations.

If the new platform achieves the efficiency mentioned in the initial assessment, IT should be able to carve off two or three physical servers to act as the initial foundation. Those initial servers should be able to receive all the migrated VMs and the continuous updates to them. Then, as you move VMs into production on the new platform, resources will free up in the VMware environment, enabling you to add a few more servers to the new platform.

A De-Risked VMware Migration

Selecting a vendor that is patient enough to walk through the above process de-risks the migration away from VMware. Each of these steps is essentially a checkpoint in the process, and you don’t move to the next step until you are confident in the results of the prior step.

Using existing hardware and providing value while you migrate are critical. If, during the evaluation process, you discover something you don’t like about the solution, you are not saddled with a bunch of hardware that you must de-install and return. And the ability to add value while you gradually migrate, in our example acting as a DR solution, puts less pressure on you to migrate too quickly.

The VergeIO Team is happy to guide you through this process, which is why we have such high customer satisfaction. The first step is to perform the upfront assessment—schedule yours now with one of our technical experts.

Hyperconverged Infrastructures (HCI) were supposed to ease IT professionals’ management burdens, but flaws in their design explain why HCI doesn’t simplify IT. These flaws have led HCI, which should be the one infrastructure for the enterprise, to be a niche solution for corner use cases within the data center. Instead of simplifying through convergence, HCI solutions from companies like VMware and Nutanix exacerbate complexity.

The HCI Flaws

  1. HCI Isn’t Scalable
  2. HCI Isn’t Flexible
  3. HCI Isn’t Secure

Because of these three flaws, complex and expensive three-tier architectures with dedicated storage arrays, restrictive compute tiers, and proprietary network switches continue to flourish despite their own challenges. Can HCI be fixed so it can finally deliver its full promise?

HCI Isn’t Scalable

How can an architecture like HCI that is scale out by design, not scale? It’s true, though; HCI can’t scale large, and it can’t scale small. Most HCI vendors force you to start with three nodes, making HCI impractical for Edge and small offices. The inability to scale small and scale large is one reason why HCI doesn’t simplify IT.

Lack of a unified code base is one reason Why HCI doesn't simplify IT
HCI Doesn’t Converge, It Squeezes

At the same time, most HCI solutions can’t scale beyond eight or so nodes without serious performance concerns. These performance concerns stem from the fact that HCI solutions don’t actually converge the three data center tiers (networking, computing, and storage). They are three separate software packages, often from three separate vendors. HCI squeezes the three separate software-based tiers onto a single server. Each of these tiers has different lanes of communication between the servers. As a result, internode communication is exponentially increased by a factor of three.

UCI Solves the HCI Scale Issue

Ultraconverged Infrastructure (UCI) solutions, like VergeOS, solve both aspects of the scale issue. It can scale small, and it can scale large. Instead of using a separate application for networking, another for compute, and still another for storage, UCI is a single piece of very efficient code.

Lack of a unified code base is one reason HCI doesn't simplify IT. UCI has a Unified Code Base
UCI Converges Networking, Compute, and Storage Into a Single Code Base

Thanks to UCI’s unification of the legacy IT stack into a single piece of software, there is only a need for a single lane of communication between nodes. The reduction in east-west traffic enables scaling beyond 200 nodes without significant network overhead. At the same time, the efficiency of the code base enables a two-node UCI environment to deliver the performance and cost-effectiveness that Edge and remote locations need. The common code base also means a unified GUI for simple administration and day-to-day operations. UCI simplifies IT by providing a single software package. It can support small offices and Edge locations while scaling to meet the needs of the primary data center.

HCI Isn’t Flexible

Another reason why HCI doesn’t simplify IT is that it restricts the type of nodes users can add to the cluster. The idea behind HCI is that as you add additional servers to the environment, you automatically scale each of the three data center tiers to support new applications or additional users. The reality is that most organizations don’t need or want to scale all three of these tiers simultaneously; sometimes, you only need additional computing power, and other times, you only need additional storage capacity.

While some HCI solutions can now add “storage-only” nodes, they compromise performance and place restrictions on data protection and efficiency. Practically speaking, most HCI solutions must use nearly identical nodes as they scale, or create an entirely separate instance with an entirely different node configuration. Each additional HCI instance further adds to data center fragmentation instead of converging it.

In some cases, vendors require customers to replace servers, even if they are only a few years old, to support the latest version of their software. This requirement is not optional with them; upgrading to the new hardware means replacing older hardware.

UCI Solves the Flexibility Issue

UCI simplifies IT by solving the flexibility issue. It allows a mixture of different nodes within the same instance. Within the instance, VergeOS can group like nodes together. Then IT can allocate some or all those resources to specific workloads. This flexible intelligence also means that customers don’t have to upgrade or replace hardware to run the latest version of the HCI software.

The efficiency of VergeOS enables customers to extract more serviceable life from aging servers while fully exploiting the capabilities of modern servers that are only a few months old. Servers within a single VergeOS instance can be from different decades, processor manufacturers, and storage types.

Lack of a flexible scale is another reason why HCI doesn't simplify IT. UCI delivers complete flexibility.

Nodes can also have different areas of focus. Some can be heavily weighted for computing power while using the storage from other nodes in the instance, and others can be heavily weighted for storage capacity or performance and provide that storage or performance to the rest of the instance.

HCI Isn’t Secure

The lack of a robust security strategy is another reason why HCI doesn’t simplify IT. Customers must fill data protection and ransomware resiliency gaps by using third-party applications and creating additional infrastructures. As a result, legacy HCI forces IT planners to look at threats like ransomware as a backup and recovery problem instead of as an infrastructure problem, which is what it really is.

After IT discovers a ransomware attack, the malware file must be found, stopped, and removed. Then, IT must methodically recover data. By only looking at ransomware as a data protection problem, the average downtime associated with a ransomware attack is typically measured in days and sometimes weeks.

UCI is Hardened and Secure

UCI simplifies IT by providing infrastructure-wide data protection and resiliency capabilities. First, VergeIO’s Virtual Data Centers (VDC), which encapsulate the entire data center, also shrink the attack surface available to ransomware. It is nearly impossible for a malware file infecting one VDC to cross over to another VDC.

Second, VergeOS’ snapshot capabilities are powered by IOclone, which provides independent, immutable copies. However, because VergeOS implements global inline deduplication at its core, clone/snapshot copies are also space efficient. Taking frequent immutable snapshots without impacting performance provides the second layer of defense against ransomware.

Third, VergeOS’ IOfortify provides early detection of a ransomware attack. With it, your notification comes minutes after an attack starts instead of coming from confused users hours later. This early detection, combined with frequent, immutable clones, means recovery occurs within minutes and with little to no data loss.

Finally, VergeOS operates as read-only firmware at its core and injects a copy of itself into each VDC. As a result, if a cyber-attack could ever get to the actual VergeOS operating environment, a known good copy at the core is available to replace it.

The Impact of HCI Complexity

The impact of HCI complexity and its limitations means that IT must use the legacy three-tier architecture. It is also why most IT professionals don’t think HCI can replace a SAN, even though it should be a better option for virtualized environments. While legacy three-tier architectures are more complicated and more expensive, they, through brute force, work through some of the issues mentioned above.

UCI fulfills and extends the potential of legacy HCI. Using a single code base allows IT to manage all aspects of infrastructure in a cohesive, straightforward manner. UCI has flexible scalability, extending to both large and small needs. UCI can mix nodes of different types, which enables true and long-lasting actual convergence. UCI’s integrated data protection capabilities eliminate the dependency on a separate data protection infrastructure. As a result, UCI delivers more widespread convergence than HCI, while delivering infrastructure-wide data resiliency.

IT has to factor the cost of the VMware Tax into its infrastructure planning. Where does this tax come from? It is the extra expense in hardware needed, to compensate for the overhead of VMware’s inefficient virtualization code. Adding additional components like vSAN for storage, or NSX for networking only makes the tax more severe. These components will adversely impact applications and users if IT doesn’t work around the overhead. These workarounds cost money, increase complexity and create a more brittle infrastructure that struggles to adapt to the organization’s future needs.

There are three primary effects of the VMware Tax:

  • A lower-than-possible VM Density.
  • The continued need for stand-alone bare-metal workloads.
  • A proliferation of the three-tier architecture.

To compensate, organizations are forced to:

  • Buy more or more powerful physical servers than what should be necessary.
  • Buy high-performance dedicated all-flash arrays.
  • Face a never-ending future of premature server and storage refreshes.

The Cost of the VMware Tax is one of the hidden costs of VMware. Learn about the rest of them in our on-demand webinar, “The 4 Hidden Costs of VMware.”

The Cost of VMware Tax on Server Planning

The first cost of the VMware Tax is that meeting the organization’s demands requires using either fewer virtual machines (VMs) per server and more physical servers or more powerful physical servers to support more VMs per server. As we discuss in our article, “HCI isn’t Infrastructure,” using more servers highlights the scaling issues common in Hyperconverged Infrastructure (HCI) and leads most customers to purchase more powerful servers to reduce cluster node count.

Using more powerful servers with more CPUs, cores, and RAM increases those servers’ costs. This approach also increases VMware licensing costs since the company charges by the physical CPU installed in its nodes, and the expectation is that after the Broadcom acquisition is complete, the company will switch to a per-core licensing strategy and is expected to raise costs even further.

Overcoming the VMware Tax with Powerful Servers

Overcoming the cost of the VMware Tax by using more powerful servers exposes the lack of flexibility when scaling, the typical VMware architecture has. More powerful servers will likely be used longer before organizational growth requires IT to add another server to the cluster. When it comes time to add additional servers to the cluster, two or three years later, that exact server type may no longer be available, or a better option may be available using a different CPU vendor. Managing nodes of different types within a VMware environment is convoluted, leading many customers to establish an entirely separate cluster, further increasing costs and complexity.

There is also the challenge of, after three or four years, the hypervisor or storage vendor may upgrade its software to the point that it no longer supports the original servers. At that point, IT is faced with refreshing its entire server infrastructure to maintain compatibility with the updated software.

The Cost of the VMware Tax on Scale

Hyperconverged Infrastructure (HCI) solutions expect a “balanced scale,” where the organization adds equal amounts of computing, storage, and networking. This requirement exposes another cost of the VMware Tax. No organization always needs to scale these three components at the same time. Especially when purchasing more powerful servers, the organization will likely need more storage performance or capacity before requiring additional computing resources.

Again, legacy HCI designs like those from VMware (vSAN, vSphere, NSX) or Nutanix expect almost identical nodes to be added to the cluster. To meet capacity demand, customers are adding servers similar to their original installation, and they end up paying for and wasting a massive amount of CPU and memory that come with those servers. Although a few vendors have evolved to allow more storage-centric nodes, these are complex band-aids with many compromises and increasing complexity. Most customers choose not to use them.

The enforcement of balanced scaling forces most customers considering HCI solutions to disqualify them later. As a result, the VMware Tax indirectly proliferates the more complex and expensive three-tier architecture.

VergeOS Enables High VM Density and Imbalanced Scale

VergeOS is a highly efficient data center operating system (DCOS) that enables high per-physical server VM populations. It does this by integrating the three standard data center tiers (networking, computing, and storage) into a single code base that is a fraction of the size in terms of lines of code without sacrificing features. This effort is the foundation of Ultraconverged Infrastructure (UCI) which moves beyond the flawed HCI model to deliver the full promise of a truly converged infrastructure.

A more compact code base means faster execution on the same hardware. Integrating the traditional data center tiers means that efficiency carries throughout the entire solution. Our typical customer can support 25 to 30% more VMs per physical server with VergeOS than their prior solution (Hyper-V, VMware, Nutanix) while running on the very same, existing hardware.

The lack of flexible scale increases The Cost of the VMware Tax

As the organization’s demands grow, VergeOS provides flexible and intelligent scaling. An optimized internal-node communication protocol ensures near-linear performance increments as IT adds nodes to the environment. VergeOS’ flexibility means that IT can add nodes of almost any type, including storage or compute-centric nodes. VergeIO has never forced the retirement of old servers to support a new version of VergeOS.

VMware Tax Encourages Bare Metal

Despite all the advantages and flexibility of virtualization, the cost of the VMware Tax means that many customers still view some applications as bare-metal only. The performance demands of these servers are just too strenuous for the virtual environment. They either starve other VMs on the same node of resources or can’t continually guarantee access to the performance these applications demand. They also tend to be certain hardware types, like GPUs, that specific applications need, which legacy solutions don’t adequately virtualize.

The result is IT must purchase and stand up dedicated silos of computing and storage for these applications, which increases costs and complexity. Additionally, these bare-metal environments don’t benefit from core virtualization capabilities like seamless VM migration.

VergeOS Delivers Near Bare Metal Performance

VergeOS’ compute efficiency also helps formerly bare-metal-only workloads to be able to realize the benefits of virtualization. Historically, many bare-metal workloads remained bare-metal because of the storage I/O demands. VergeOS integration of storage, coupled with the performance of its file system, delivers near-bare-metal performance for these workloads. The VergeOS storage component, VergeFS, ensures all reads are local to the virtual machine. Finally, VergeOS supports nodes of various CPU classes within the same instance. Our customers can and do mix Intel, AMD, and GPU-based nodes, even of different generations. They repeatedly tell us that they were able to virtualize formerly bare-metal workloads without any degradation of performance.

Conclusion

With its inefficiencies and subsequent costs, the VMware Tax represents a significant concern for IT infrastructure planning. Its impact on VM density and the push toward bare-metal workloads signifies the increased expenses and complexities organizations face. As the technology landscape continues evolving, solutions like VergeOS emerge as viable alternatives, offering enhanced VM densities and near bare-metal performance.

VMware VM to VergeOS Chalktalk

By merging the conventional data center tiers and focusing on efficient operation, VergeOS addresses the challenges posed by VMware’s model and presents a forward-thinking solution that adapts to an organization’s dynamic needs. As organizations strive for agility, cost-effectiveness, and scalability, transitioning to platforms prioritizing these attributes will be paramount. VergeOS makes that transition seamless thanks to our IOmigrate capability.

HCI isn't an Infrastructure

As IT leaders consider the practicality of a VMware exit, they will also consider hyperconverged infrastructure. However, the inability to scale flexibly means that HCI isn’t an infrastructure they can use as a replacement platform. Even the few HCI solutions that are not dependent on VMware as their hypervisor suffer the problem of brittle scalability.

The Three Requirements of Flexible Infrastructure

A flexible infrastructure must meet these three requirements:

  1. The ability to scale small, less than three nodes for Edge, Remote Office, and small business data centers.
  2. The ability to scale large, dozens to hundreds of nodes, to meet the demands of an enterprise data center.
  3. The ability to manage nodes of different types, CPU brands, compute-only, and storage-only, so that it can adapt to the ever-changing needs of the data center.

The inability to meet these requirements with a single solution means that if an organization selects HCI as its infrastructure strategy, it likely will either need multiple HCI solutions to cover the organization’s needs, or at least multiple instances of the same HCI solution. Ironically, Hyperconverged Infrastructure (HCI) isn’t an infrastructure, nor does it converge.

UCI is Infrastructure

Because of its inflexibility, a counter to HCI, which is relegated to niche use cases, is Ultraconverged Infrastructure (UCI). UCI is an infrastructure, Data Center Operating System (DCOS), and does truly provide convergence. VergeOS is a UCI solution that can scale small, large, and is flexible which allows it to adapt to the changing needs of organizations. Additionally, it is not dependent on VMware, which makes it an ideal alternative for customers looking for a VMware exit.

Infrastructure Must Scale Small

Not every business is an enterprise, but most need compute capabilities beyond what cloud-based SaaS applications can provide. As those businesses scale, the cost of the cloud becomes a significant factor. The point of entry for most HCI solutions is a three-server configuration which becomes nodes in its cluster. This requirement is often too large for Edge, Remote Office, and Small Data Center use cases.

As a result of the inability to scale small, most IT planners rule out HCI for these use cases and compromise with standalone servers and an inexpensive shared storage solution. The compromise increases the cost of acquiring the hardware and software for Edge, Remote Office, and Small Data Center use cases, and it increases complexity in an area that must have simplicity. These use cases have limited or no IT administrators, especially at the Edge.

UCI Scales Small

Users can start with as few as two nodes, and because of VergeOS’ efficiency, those nodes can be very cost-effective mini-servers, ideal for the Edge or Remote Office use cases. Even small data centers can run comfortably on two or three low-end to mid-range servers, reducing hardware acquisition costs by 50% or more. Learn more about the advantages of using UCI in small data centers here.

VergeOS’ efficiency comes from its tight integration of the network, compute, and storage tiers into a single, cohesive data center operating system (DCOS). The actual convergence of those tiers, instead of HCI’s approach of an “elegant bundle,” means the elimination of redundant metadata tables, databases, APIs, and management tools. The result is that the underlying hardware is unchained and enabled to reach its full potential.

Infrastructures Must Scale Large

Small businesses grow to medium-sized businesses and then eventually to large businesses. Starting over with a new infrastructure as the business grows is costly and risky.

Again, most HCI solutions start too big to be viable for small data centers or Edge, but the few that focus on the smaller end of the market often can’t scale large enough to meet the organization’s demands as it grows. They often can’t scale past six to eight nodes. The result is IT must replace the “starter-HCI” solution with another more scalable solution. The replacement often includes replacing hardware since each HCI solution seems to have a unique hardware compatibility list or comes “bundled” with hardware.

Even so-called enterprise HCI solutions have limitations and can scale to only a few dozen nodes, which is not large enough to provide complete infrastructure consolidation. There is also a practical limit to how large HCI solutions can scale. Most vendors use standard IO protocols to communicate between nodes, which means that every node must be “touched” every time a packet is received by the cluster, creating an untenable amount of internode, or east-west traffic.

Yet another part of the challenge is that most HCI solutions don’t include complete layer 2 and layer 3 networking functionality in their product. At most, they provide virtual switching or they bundle in, yet again, another third-party software-defined networking product. The lack of native networking functionality means that HCI clusters can’t practically scale to more than a dozen nodes without suffering a performance impact.

These challenges are why the legacy three-tier architecture continues to be the bread-and-butter infrastructure for enterprises. It is also why most IT leaders believe that HCI cannot replace standalone networking, virtualization, and storage.

HCI isn't an Infrastructure

UCI Scales Large

VergeOS can not only start as small as two nodes, but it can grow to well over one hundred nodes. Organizations of any size can start using VergeOS with confidence that it can grow or shrink, to meet their needs. The team at VergeIO also developed a proprietary networking protocol that optimizes internode communication, significantly reducing east-west traffic and making scale technically possible and practical.

Infrastructure Must Scale Flexibly

Infrastructure flexibility is a critical requirement because small and large businesses evolve. Their IT needs are not static, and neither should their infrastructure be. It needs to adapt to innovations in hardware and business needs.

Most HCI solutions are rigid in their configuration, only supporting specific hardware and forcing customers to upgrade to new hardware as the infrastructure software is updated. In HCI terms, scaling up typically means adding identical nodes, making it difficult to take advantage of the latest hardware advancements or adopt new types of nodes, such as storage-only or compute-only. HCI’s lack of flexible scaling also poses challenges when organizations want to retire or replace outdated equipment. Mixing old and new equipment within the same cluster is almost impossible.

The typical HCI setup often means organizations must create separate instances for workloads and hardware types. This approach fragments the overall infrastructure and creates more complexity, reducing operational efficiency and leading to underutilized resources. The inability to mix and match different types of nodes within the same cluster further diminishes the flexibility and cost-effectiveness of HCI.

UCI Scales Flexibly

On the other hand, UCI provides an answer to the rigidness of HCI. VergeOS supports multiple types of nodes, such as compute-only or storage-only nodes, which allows it to scale flexibly to match the dynamic needs of the business. As technology evolves and new hardware becomes available, VergeOS users can integrate these advances seamlessly into their existing setup. Customers can, for example, mix in AMD, Intel, and GPU nodes into the same instance.

Furthermore, with VergeOS, it’s possible to maintain a diverse set of hardware in a single instance, preventing infrastructure fragmentation. This capability allows businesses to adjust their IT setup as the organization grows and its needs change, ensuring they always have the most cost-effective and efficient infrastructure.

HCI isn't an Infrastructure


Conclusion

VergeOS is an ideal solution for businesses seeking a flexible, scalable, and efficient IT infrastructure. UCI surpasses HCI in meeting the demands of a dynamic business environment, ensuring that businesses can focus on their core competencies without worrying about their infrastructure. Whether it’s a small enterprise looking to grow or a large organization needing to maintain agility and efficiency, VergeOS has the features and flexibility to accommodate their needs. Compare HCI with UCI here.
