5 questions to ask before choosing managed Kubernetes. Conformance, portability, monitoring, support, and deployment — covered.
Every managed Kubernetes offering promises simplicity. Fewer promise portability, transparency, and long-term freedom. Before you sign, ask the questions that separate marketing from architecture.
As enterprises expand their cloud-native capabilities, they are increasingly confronted with challenges that reshape how they evaluate their cloud strategies — from data residency and legal exposure to long-term pricing predictability and dependency on hyperscale providers. In fact, Flexera's State of the Cloud Report 2025 shows that 84% of enterprises struggle with cloud spend management and vendor lock-in — two issues that only sharpen once you're running production workloads on a Kubernetes platform you can't easily leave.
This checklist won't name names. It doesn't need to. The right criteria will tell you everything.
1. Is It Upstream-Conformant Kubernetes — or a Fork?
Not all managed Kubernetes is the same Kubernetes. Some providers ship modified distributions with proprietary extensions baked into the control plane or networking layer. That means your manifests, tooling, and operational knowledge may not transfer cleanly to another environment.
Ask whether the platform participates in the CNCF Certified Kubernetes Conformance Program. Software conformance ensures that every vendor's version of Kubernetes supports the required APIs, as do open source community versions. For organizations using Kubernetes, conformance enables interoperability from one Kubernetes installation to the next and allows them the flexibility to choose between vendors.
What to ask:
- Is the offering CNCF-certified for its current Kubernetes version?
- Does the provider ship pure upstream Kubernetes, or a proprietary fork?
- Can I run standard kubectl and Helm charts without platform-specific modifications?
VEXXHOST only makes use of upstream Kubernetes, ensuring that the code delivered is from the official version of the projects. VEXXHOST is a Silver member of the Cloud Native Computing Foundation (CNCF), and its Kubernetes solution is certified as part of the CNCF Certified Kubernetes Conformance Program, meaning workloads remain genuinely portable.
2. Can You Actually Leave?
Portability isn't a feature you test on day one — it's the one you need on the day your strategy changes. If the provider layers proprietary service meshes, custom ingress controllers, or non-standard storage integrations into the platform, migration becomes a rewrite, not a lift. And that rewrite has a price tag — 55% of IT leaders say egress and data transfer costs alone are the biggest barrier to switching providers. Lack of portability isn't just an architecture problem. It's a financial one.
What to ask:
- Are storage classes backed by standard CSI drivers, or proprietary plug-ins?
- Does the platform use standard Kubernetes APIs for load balancing, autoscaling, and RBAC?
- Can I export my cluster configuration and reproduce it on another conformant platform without refactoring?
VEXXHOST runs 100% upstream OpenStack and Kubernetes with standard APIs and no proprietary extensions — your workloads stay portable, and you can migrate anytime.
3. Is Monitoring Included — or an Upsell?
Observability should not be an afterthought bolted on at additional cost. If your provider charges extra for metrics, logging, and alerting — or expects you to bring your own stack — you are absorbing hidden operational complexity from day one.
What to ask:
- Does the platform ship with integrated monitoring, logging, and alerting out of the box?
- Are dashboards pre-configured for cluster health, storage, and networking — or do I build them myself?
- Is the observability stack based on open standards (Prometheus, Grafana, Loki), or proprietary tooling?
Atmosphere includes full day-2 operations for monitoring, logging, and alerting out of the box using Prometheus, AlertManager, Grafana, and Loki. Observability comes from the same Prometheus and Grafana stack the Kubernetes ecosystem already standardized on — there's no separate monitoring system to operate for the infrastructure layer. Atmosphere includes over 300 pre-built alert rules, developed based on real production incidents.
4. Who Answers the Phone at 2 AM?
Support models vary wildly. Some providers offer community forums and ticket queues. Others give you direct access to engineers who actually work on the upstream projects your infrastructure depends on. The difference shows up when something breaks in production at scale.
What to ask:
- Is 24/7 support included, or tiered behind premium plans?
- Does the support team have upstream contributor-level expertise, or is it general L1/L2 only?
- Does the provider handle incident management proactively, or only respond to tickets?
VEXXHOST's fully managed Kubernetes Enablement offering means that users benefit from extensive support, upgrades, monitoring, and incident management. VEXXHOST engineers are available around the clock, and complex issues get escalated to core contributors. The team consists of active contributors to OpenStack, Kubernetes, and Ceph — they don't just run the platform, they help build it.
5. Can You Deploy It Where You Need It?
A managed Kubernetes platform that only runs in one provider's region is not managed infrastructure — it's a leased environment. True deployment flexibility means hosted, on-premises, or hybrid — on your terms, under your governance.
Check our blog on data sovereignty and Kubernetes infrastructure for more insights.
What to ask:
- Can I run this on my own hardware, in my own data center?
- Does the provider offer hosted, on-premise, and hybrid deployment models?
- Can I choose between fully managed operations or a supported self-run model?
VEXXHOST delivers pure upstream Kubernetes — hosted or on-premise, managed or supported — your clusters, your way. Atmosphere is available in Cloud, Hosted, and On-Premise editions, offering diverse functionalities to meet distinct needs. That means the same platform, the same support, and the same open-source foundation — regardless of where it runs.
To Sum up
Choosing managed Kubernetes is an infrastructure decision with multi-year consequences. Kubernetes is no longer a trend — it is the backbone of cloud-native computing. The questions above aren't designed to disqualify providers. They're designed to reveal what you're actually buying: freedom or dependency, transparency or abstraction, a partnership or a contract.
VEXXHOST is built on proven open-source technologies — no proprietary lock-in, ever. No hidden fees. No egress charges.
