Infrastructure as a Service (IaaS) gives enterprises the agility and scalability of cloud without handing away control of the operating system and application layer. But the market is crowded, and providers look similar on a feature sheet. This article covers the fundamentals every buyer checks — and then the three factors that separate a good enterprise decision from a costly one.
1. Performance and underlying infrastructure
The provider's hardware directly shapes the experience your applications deliver. Look beyond vCPU counts to the real determinants of performance:
- Storage tier and IOPS — SSD/NVMe rather than legacy spinning disk.
- Network latency and throughput between compute, storage and the internet edge.
- The virtualization platform and how noisy-neighbour effects are controlled.
2. Scalability and elasticity
Your workload will change. Confirm the platform scales both vertically and horizontally, that resource increases can be provisioned quickly (ideally self-service), and that automation is available via API or portal so operations stay efficient as you grow.
3. SLA and support depth
Cloud runs 24/7, but value evaporates if you cannot reach competent support when something breaks. Examine the uptime guarantee, the response and resolution commitments, and — critically — the technical depth and language of the support team. An SLA number means little without the engineering behind it.
4. Security and compliance
For most enterprises, security certifications and regulatory alignment are non-negotiable. Check for recognized standards (ISO 27001, ISO 22301), network security layers (WAF, IDS/IPS), physical data-center controls, and alignment with the regulations that apply to you (KVKK, GDPR, PCI DSS).
5. Pricing transparency
Headline prices can hide real cost. Favour providers that bill resources transparently (compute, memory, storage and traffic itemized), expose usage in real time, and offer genuine pay-as-you-go flexibility rather than opaque bundles.
The three enterprise differentiators
Data residency. Where your data physically sits determines which laws apply and how hard your audits will be. If you serve regulated markets — or operate in Turkey under KVKK — a provider with local data centers lets you keep data, backups and logs in-country by design.
Exit strategy. The best time to plan your exit is before you sign. Ask how you get your data and workloads out: standard formats, no punitive egress traps, documented migration support. A provider confident about portability is a provider worth trusting.
Managed services. Raw IaaS still leaves patching, monitoring, backup and incident response on your plate. A provider that also offers managed operations lets you offload that burden selectively — keeping control where you want it and handing off the undifferentiated heavy lifting.
The Cloud Expert approach
Cloud Expert delivers enterprise IaaS on a VMware-based platform — so teams work with familiar management tools — with transparent, usage-based pricing and Turkey-located, KVKK- and GDPR-aligned data storage. Our managed services option means you can run the infrastructure yourself or let our team operate it 24/7.
