Every platform we get compared to

One page per product, written for the people doing the evaluation. Some of these you would replace with edgeContinuum. Others solve a different layer and can sit alongside it, and those pages say so. Start with whatever you run or are shortlisting today.

Pick the stack you are moving from

Each of these pages runs the same ladder: every piece of the platform you have today, and what it becomes when the infrastructure is OpenStack and the services on top are managed. They are written to be read before a call, not after one.

Start here if you know what you are replacing. If you are still deciding whether to replace it, the shortlisting guide works through the four routes out of VMware first, and the migration guide covers execution once the direction is set. For Kubernetes specifically, the Kubernetes on OpenStack architecture guide and the OpenStack self-service platform architecture guide cover the layer above the hypervisor.

Or compare the layer above OpenStack

These three are not hypervisors, they are products that sit where edgeContinuum sits, on top of an OpenStack somebody already runs. The pages are written to be useful even if you pick the other one: each says plainly what the other product does better, because the honest answer usually depends on which layer you are trying to solve.

Bring your own inventory

Book a call and we will walk your current stack through the ladder that fits it, or request a free trial and provision managed services on your own infrastructure.

Frequently asked questions

Which comparison should we read first?
The one matching your virtualization layer: vSphere, Nutanix AHV or Proxmox. If your question is about Kubernetes platforms specifically, start with the OpenShift or Tanzu page.
Is OpenStack a requirement in all of these?
Yes, OpenStack is the foundation in every case, and edgeContinuum manages that layer so your team consumes services instead of operating the plumbing.
How is edgeContinuum priced against these platforms?
A subscription per resource managed through the platform (clusters, databases, VMs), independent of cores, sockets, nodes or users, and identical from SaaS to fully air-gapped.
Should I read the VMware alternative page or the OpenStack vs VMware page?
They answer different questions and it is worth picking the right one. The VMware alternative page is about the destination: what edgeContinuum replaces in a vSphere estate, what the licensing arithmetic looks like after Broadcom, and which hypervisors are on a realistic shortlist. The OpenStack vs VMware page is about the comparison itself: who provisions, what the licence meter counts, and how much operational work comes back to your team. If you have already decided to leave, read the first. If you are still testing whether open infrastructure is credible, read the second.
Which comparison applies if we run both vSphere and Nutanix?
Read both pages, because the two stacks fail differently and you will be solving two problems. The vSphere side is usually a licensing and bundling problem, so the VMware alternative page frames it correctly. The Nutanix side is usually a hardware-coupling and per-node problem, which the Nutanix alternative page addresses. The useful news is that the destination is the same for both: one OpenStack estate with a managed layer over it, so mixed estates consolidate rather than fragment further.
Do we have to move everything at once?
No, and we have not seen an estate that did. The platform runs beside what you have today, so workloads move in waves and both stacks stay live through the transition. Most teams sequence by renewal pressure, taking the workloads whose licence costs bite first and leaving the awkward single-instance legacy systems until last. Each page here describes the destination for one starting point; the sequencing is a conversation with your engineers, not a property of the product.
What about Platform9, Fleio, OSIE or meshStack?
The first three have their own pages above. They belong in a different group from the hypervisor comparisons, because they sit where edgeContinuum sits rather than underneath it: Platform9 can supply the private cloud platform itself, while Fleio and OSIE put a portal and a billing system over an OpenStack you already run. meshStack is a different category again. It is an internal developer platform that governs and orchestrates cloud accounts across AWS, Azure, Google Cloud, Kubernetes and OpenStack, and it does not operate infrastructure or run managed services itself, so a head to head comparison would mostly mislead. If you are choosing between them, you are usually answering two different questions rather than one.
Which page should a service provider read first?
Start with the service provider page rather than any of the platform comparisons. The comparison pages are written for teams replacing something they run for themselves, where the question is capability and cost. If you are selling managed services on your own infrastructure, the deciding factors are different: isolated organizations per client, quotas that hold, per-tenant usage tracking, and a catalog you curate. Come back to the comparison pages afterwards for whichever stack you are actually displacing.
