If you are frustrated with VMware’s high prices, exorbitant renewal fees, stalled innovation, and declining support, you may be looking at the Public Cloud as a VMware alternative. Public Cloud providers like Amazon AWS, Microsoft Azure, and Google Cloud have their use cases. Still, as we’ve seen in the recent rash of cloud repatriation moves, the Cloud is not necessarily the ideal solution for all use cases.

The first question is, “Does the Public Cloud meet the requirements of a VMware Alternative?”

Requirements for a VMware Alternative:

  • Have a lower upfront cost
  • Lower long-term costs
  • Provide superior performance and capabilities
  • Offer world-class support

This blog will explore how the Public Cloud stands up to these requirements.

The Upfront Costs of the Public Cloud

Upfront costs are an area where most analysts suggest that the Public Cloud has an advantage over VMware and other VMware alternative solutions. But does it? In the VMware alternative use case, you already have the hardware! The bigger question is, can the potential VMware alternative use your hardware? In most cases, the answer is “no” or “not very well,” so in those cases, the Public Cloud has an upfront cost advantage because you only have to pay the first month’s “rent” for the hardware and software you need.

VergeOS is an Ultraconverged Infrastructure that rotates the traditional IT stack (hypervisor, storage, and network) into a linear plane and a single software code base. This integration is essential because it creates a data center operating system that is 50% or more efficient than legacy, fragmented solutions. Unlike traditional Hyperconverged Infrastructure (HCI), VergeOS can run on existing hardware and deliver more capacity and performance. See our HCI to UCI comparison page for more details.

The Long-Term Costs of the Public Cloud

An area where the Public Cloud as a VMware alternative does not fare well is in the long-term cost calculation. The repeated monthly rental of the same infrastructure adds up quickly, which is why we see a rash in Public Cloud departures. The Public Cloud is ideal for short-term projects that you will spin up quickly and then tear down after getting the answers you need or validating a concept. It is not ideal for long-term, relatively static environments that will run for years, even decades.

Most customers we speak to looking for a VMware replacement have been running their VMware infrastructure for five years or more. The servers that support that environment are typically three to five years old. Even if you are very judicious about cloud resource utilization (which most people don’t have the time for), over five years, you will spend significantly more for the cost of renting that compute from the Public Cloud versus owning it outright, especially in the VMware or VMware alternative use case.

VergeIO has a long-term cost advantage over the Public Cloud, VMware, and VMware alternatives, thanks again to the extreme efficiency of VergeOS. Our software allows you to extend the life of IT infrastructure further than you ever thought possible. Many VergeOS customers are running on servers and storage that are over six years old.

The Performance of the Public Cloud

In theory, the performance of the Public Cloud should be an advantage when IT Professionals consider it a VMware alternative. If you need more processing power, rent more processors; if you don’t, deactivate them. This theory may hold if your application is scalable across multiple processors and cores. Most applications are not that threaded, and throwing more processing power at them doesn’t help. Additionally, performance isn’t just about processor performance. In most cases, the bottleneck is either poor application code or storage I/O performance.

Storage performance is an area where the Public Cloud struggles. High performance is costly and often far more challenging to configure. The built-in capabilities of the Public Cloud, especially in terms of storage, are so weak that there are dozens of products from third-party software developers that organizations need to sift through to try to fill the gaps.

VergeIO’s approach directly integrates a complete suite of storage services into VergeOS. Storage is an equal citizen alongside the hypervisor and network capabilities. The storage capabilities of VergeOS are so powerful that many companies begin their VMware Exit Strategy by selecting VergeOS instead of going through yet another SAN replacement.

World Class Support

The Public Cloud as a VMware Alternative

The quality of support from both VMware and the Public Cloud varies wildly. With VergeIO, all customers, regardless of size, experience high-quality support with quick resolution to your questions. VergeIO also provides customers with a world-class support experience. We know that VergeOS doesn’t live in a vacuum, and we go above and beyond, even helping customers resolve issues with non-VergeOS-related challenges. Quality support is easy to claim but harder to deliver. Take our product for a test drive, experience our support firsthand, or speak with our customers.

How to Start Your VMware Exit

VergeOS is usually 50% less than the price of VMware, and it leverages your existing hardware so you can benefit from those savings almost immediately. Our efficiency will extend the life of your current hardware, further increasing your savings. Finally, the operating system delivers better performance, data protection, and greatly simplified operations.

You can start by scheduling a test drive. Using our Virtual Data Center technology, we create a virtual environment. Within minutes you’ll be up and running without having to deploy hardware.

Your next step might be using VergeOS as a disaster recovery copy of your VMware environment. If you have a few different servers, you can load our software on them and create a complete VMware disaster recovery plan without a substantial financial outlay. This option allows you to take an inexpensive extended use of our solution while adding value to and reducing the cost of your current infrastructure.

While using VergeOS as a VMware DR solution, you might also want to use your VergeOS infrastructure for new workloads. Then when you’re ready, you can use our DR technology to move your VMware environment to VergeOS seamlessly. Again, transition at your pace, knowing we will be there every step of the way.

Ann Arbor, Mich, April 25th, 2023 — VergeIO, the Ultraconverged Infrastructure (UCI) company, today announced the launch of IOclone, a new solution that solves the virtualization snapshot problem facing users today. VMware and other virtualized environments suffer from highly inefficient snapshots and because of performance concerns, customers can only maintain a few active snapshots. This level of retention is insufficient for adequate data protection. With IOclone, customers can now leverage the built-in global data deduplication capabilities of VergeOS to create complete clones of virtual machines (VM) within milliseconds, regardless of VM size. Each clone is immutable and space efficient, initially consuming no additional capacity.

Hypervisors without the powerful capabilities of IOclone require customers to use expensive array-based snapshots or integrate with backup software solutions, forcing customers into an expensive and complicated multi-step solution for data protection. By comparison, IOclone is a single-step process tightly integrated into VergeOS. Once IT sets up a cloning policy, snapshots happen regularly without administrative intervention.

Now customers can create and maintain thousands of space-efficient copies of virtual machines or even virtual data centers without impacting performance. Both the original production instance and clones perform at the full performance of the infrastructure. Clones are instantly available for use in testing, QA, and development purposes, or customers can create “golden masters” and spawn hundreds or even thousands of VMs or virtual data centers (VDCs) from the original, again without impacting performance.

“Both clones and snapshots typically have some overhead in the capacity they consume and the processing required to use them. Clones typically have to make a copy of all of the metadata information, which means the cloning process takes some time upfront, but then they are ready to use and independent. Snapshots trade up front processing time and instead show performance degradation when in use or during clean-up,” said Greg Campbell, VergeIO founder and CTO. “IOclone delivers the best of both. Because our deduplication is part of the metadata in our filesystem, we get all the performance and independence benefits of cloning without their upfront overhead.”

Customers can execute IOclone on the virtual machine, the volume, or an entire virtual data center (VDC). In the same way that a virtual machine is an encapsulation of a server, a VDC clone is an encapsulation of the entire data center. It includes all the VMs within the data center and all the storage and networking policies, delivering near-instant recovery. 

IOclone does not require specialized storage controllers or storage data processing units. Thanks to the efficiency of VergeOS, it works with off-the-shelf servers using commodity flash and hard disk drives within the VergeOS environment. It is integrated into VergeOS and is available now at no additional charge to VergeOS customers. Customers looking to migrate off VMware can leverage VergeIO’s IOprotect and benefit from the immutable limitless protection of IOclone.

To learn more about IOclone, join VergeIO for “TechTalk, A Deep Dive into Virtual Infrastructure File Systems.” Live on May 4th at 1:00 PM ET / 10:00 AM PT.

snapshots or clones for data protection

Most storage solutions will provide IT professionals with either snapshots or clones for data protection, but are the differences between the two functions significant enough to make it part of your selection criteria? Like all things in IT, the answer depends.  In this case, it depends on if and how your vendor implemented the two technologies. 

Register now to join us live on May 4th for technical deep dive into virtual infrastructure file systems and see a live demonstration of IOprotect.

What Are Snapshots?

Deciding if snapshots or clones are best for data protection first requires understanding how the two technologies work. First, let’s look at snapshots. Most storage solutions, be they a filesystem or block storage, have a metadata layer that points to where each data segment resides. A snapshot makes a copy of those pointers at a specific time and then sets those blocks pointing to a read-only mode until it expires. 

Snapshot Update Methods

There are two methods for updating a read-only segment because of a snapshot.  The first method is a copy-on-write process. When a user or application attempts to update or change an existing segment, the storage solution copies the old segment to a new location and allows the new data to occupy the original segment. The storage solution then updates the snapshot metadata with the old segment’s new location. 

The second snapshot update method is “redirect on write”. Using this method, the storage system will write the modified data to a new location and update the metadata of the “production view” of the data. It does not need to update the “snapshot view” of the data. 

Both of these methods limit the scalability of snapshots because multiple writes and multiple changes to metadata need to occur. Also, many storage systems use separate metadata trees to manage each snapshot. As the number of snapshots increases and the depth of those snapshots (snapshots of snapshots), the complexity of managing and updating the metadata wears on system performance.  As a result, where the snapshot is occurring within the hypervisor, on the same hardware as the hypervisor (software-defined storage running as a virtual machine), or on dedicated storage hardware, there are limits to how many snapshots the storage solution can maintain. 

The complexity shows itself by degrading overall system performance. Storage systems with legacy snapshot technology require:

  • Limitations to number of copies retained
  • High-end processors in the storage servers
  • Dedicated data processing units (DPUs)
  • Days to remove old snapshots

What Are Clones?

Clones are copies of existing segments. They are more standalone, and updating a clone does not require the same metadata overhead as snapshots. The independence of a clone means that they don’t suffer from performance degradation as snapshots regardless of how many there are or how long they are retained. Clones don’t need either of the sophisticated update methods that snapshots require.

The Downside to Clones

The typical downside to clones is that they are either complete copies of the original volume or deduplicated copies. A full copy, means that data must traverse the internals of the storage infrastructure, travel across the network to the hypervisor, and back down the network again to the storage system. 

Some hypervisors have initiated capabilities to eliminate traversing the network, saving time. Still, most cloning functions must process data through the internals of the storage solution twice, even if that solution has a deduplication feature. With deduplication, the resulting clone may not consume any additional capacity, but the time to create that copy is still significant, especially if the volume is of any measurable size. It is best not to use the applications while the storage solution clones it. As a result, most organizations don’t use cloning as part of their data protection strategy. 

IOclone — The Best of Clones and Snapshots

As we’ve discussed, clones and snapshots typically have some overhead in the capacity they consume and the processing required to use them. Clones typically have to make a copy of all of the metadata information, which means the cloning process takes some time upfront, but then they are ready to use and independent. Snapshots don’t have the upfront processing time and, as a result, are ready for use almost instantly. However, they show performance degradation as the number of snapshots increases when used or during snapshot clean-up routines. 

IOclone is a capability of the VergeOS operating system that combines the best of clones and snapshots into a single solution. Since global inline deduplication is part of the metadata in VergeOS, IOclone, copies are similar to snapshots. Regardless of capacity, it can create clones of VMs, volumes, or entire virtual data centers in milliseconds. At the same time, IOclone-created copies have the stand-alone performance of independent clones without initially consuming additional capacity footprint.

With IOclone, IT doesn’t have to choose between snapshots or clones for data protection. This capability within VergeOS can retain hundreds, even thousands of copies of VMs, volumes, or entire Virtual Data Centers (VDC) without negatively impacting performance or capacity consumption.

Conclusion

IOclone is also part of our IOprotect solution, which enables you to start a VMware Exit by first using VergeOS as a disaster recovery solution. Most customers find IOprotect reduces the cost of disaster recovery by more than 50% without adding additional hardware. It provides a complete recovery environment, converging disaster recovery so that data, applications, and the processing power to recover are all available from a small cluster of nodes. 

As your confidence in VergeOS grows, you can use it for your production environment. The tightly integrated VergeOS architecture delivers more efficient performance, increasing workload density on less physical hardware. Once your conversion is complete, you’ll lower costs by as much as 80% and enjoy an actively developed data center operating system with unparalleled support.

VMware Scale Comparisons to VergeOS

During our “InBrief” Event with Truth In IT, one of the most frequently asked questions was about VMware scale comparisons. This series of questions moved beyond the more general Comparing VMware to VergeOS and focused specifically on how VergeOS handles the demands of scale compared to VMware.

To learn more about VergeOS’ scaling capabilities, watch our on-demand webinar “How to Eliminate the Data Center Scale Problem.”

Understanding VMware Scale Methods

Before making any VMware scale comparisons, you must understand its scaling methodology. How VMware scales depends mainly on the infrastructure on which it resides. Most VMware environments use the classic three-tier architecture with physical network switches, servers, and a separate storage system. Most organizations have one primary switch and server vendor, although a few alternate brands may be in use. However, the storage tier, especially as the environment scales, typically has multiple storage systems for different virtual machine (VM) types or use cases.

A less popular alternative is the classic hyperconverged infrastructure (HCI) which loads software-defined networking (SDN) and software-defined storage (SDS) software onto the same nodes as VMware ESXi. In most cases, the SDN and SDS software run as VMs and are subject to ESXi capabilities. As a result, the organization still has a three-tier architecture. It is just that those tiers are now logical instead of physical. This logical representation of the three-tier architecture is why the classic three-tier architecture remains so prevalent.

These two infrastructures impact the scalability of VMware. VMware claims to support 96 nodes per ESXi cluster in the classic three-tier architecture, but only 64 nodes within its HCI cluster because of limitations within the vSAN cluster.

Understanding VergeOS Scale Methods

VergeOS is an ultraconverged infrastructure (UCI). Similar to HCI, it does not use an external storage array. Unlike HCI’s use of separate SDN and SDS software inside the hypervisor, UCI integrates the networking and storage functionality into the hypervisor. This critical difference significantly improves the ability to scale the infrastructure, especially when you compare UCI to HCI. There is no technical limit on the number of nodes VergeOS support, and there is no case of “diminishing returns” as you scale. We have customers in production with over 60 active nodes in a single VergeOS instance.

Comparing VergeOS to VMware Scale

When making VMware scale comparisons, there are two aspects to remember. First, what are the technical limitations of scalability, and second, what are the ramifications of scaling the cluster on resource utilization and organizational flexibility?

VergeOS’ Technical Scale is Better Than VMware Scale

VergeOS is superior in raw node count versus VMware, enabling large enterprises to meet even the most demanding processing and storage performance requirements. Again, we have production customers with over 60 nodes, hundreds of virtual data centers, and thousands of virtual machines. These customers have been running VergeOS at this level of scale for years. VergeOS customers also don’t need to worry about scaling complexity. With VergeOS, there is only one software package, not three or more.

VergeOS’ Efficient Scale is Better Than VMware Scale

VMware scale comparisons to VergeOS should also include how efficiently the infrastructure scales. While raw node count may be critical for some data centers, most organizations seek more efficiency and flexibility in how the VMware alternative scales. Efficient scale means only adding additional nodes after the existing nodes’ resources have been used to their full potential. An efficient infrastructure can deliver more performance from fewer nodes, which lowers both capital and operational costs.

The comparison of efficient scale is where VergeOS has a clear and more practical advantage. We repeatedly have VMware customers moving to our platform and are seeing better performance from their applications even though it runs on the same hardware. The lack of efficiency is why many customers who originally consider HCI end up selecting a classic three-tier architecture. UCI delivers the efficiency they need.

As a result, customers can add even more workloads to the environment without purchasing additional hardware. In some cases, they have been able to delay new server purchases for years, thanks to the implementation of VergeOS. The efficiency results from integrating the networking and storage components and, frankly, just better execution of the code. Our efficiency means that while customers can scale further with VergeOS, they won’t have to scale as often.

VMware Scale Comparisons to VergeOS must include range of scale
VergeOS can scale small for the Edge and large for the Enterprise. Each node is used to its full potential.

VergeOS’ Flexible Scale is Better Than VMware Scale

VMware scale comparisons to VergeOS must also include how flexible it is to scale the cluster. Most customers will want to start small and add nodes as workloads and organizational growth demand it. Instead, most customers will grow their environment over time. During that time, their needs will change, and so will technology. The first dozen or so nodes they start with may only be available after the time they add their fiftieth node.

With VMware, you must create an entirely separate cluster if you add different servers with different configurations, like an AMD processor instead of an Intel processor. While there is a common management interface, plenty of functions need to be set separately. HCI Storage is a good example. It is locked to the cluster and can’t be shared across clusters.

With VergeOS, IT can bring in servers of vastly different configurations, different processors, different storage media types, and even with GPUs. They are all managed by a single VergeOS environment. Resources can be isolated to a single virtual data center or distributed across multiple virtual data centers.

VergeOS’ flexibility means that the software can adapt to the organization’s needs and integrate new hardware innovations. IT can use VergeOS for mainstream applications with modest performance requirements, then add high-performance nodes with GPUs and NVMe flash or high-capacity nodes for file sharing and backup. Each of these different hardware configuration types is still managed within the same VergeOS instance.

Conclusion

VMware scale comparisons to VergeOS will show how superior VergeOS is in all the ways IT measures scalability. It is affordable for small data centers and enables them to deliver more performance on less hardware while also providing robust networking functionality. Enterprises can support various workloads thanks to VergeOS’ ability to mix nodes and use Virtual Data Centers. There is no technical limit on how many nodes, VergeOS supports, but its efficiency means you will require less than VMware.

It is also important to remember that VergeOS is a complete offering and requires no compromises versus VMware. It provides robust data protection, massive capacity scalability, and almost bare-metal performance of virtualized applications. VergeOS’ storage capabilities are so powerful that many customers switch to VergeOS as part of a SAN replacement project.
