Choosing a cloud provider is one of the highest-impact infrastructure decisions an engineering team makes. The wrong choice creates years of migration pain and wasted spending. The right choice accelerates development, reduces costs, and scales with your organization. This guide provides a systematic 6-factor framework for evaluating providers, with real pricing data and a head-to-head comparison table.
According to Flexera's 2025 State of the Cloud Report, 89% of organizations use a multi-cloud strategy, but 67% report that managing multiple providers is their top challenge. Starting with the right primary provider reduces multi-cloud complexity significantly.
The 6-Factor Evaluation Framework
Factor 1: Compute Pricing
Compute is 40-60% of most cloud bills. Comparing equivalent instances across providers reveals significant pricing differences.
| Provider | 4 vCPU / 16 GB VM (Monthly) | 8 vCPU / 32 GB VM (Monthly) | Managed K8s Control Plane | Spot Discount |
| AWS (us-east-1) | $121 (m6i.xlarge) | $243 (m6i.2xlarge) | $73/mo (EKS) | 60-90% off |
| Azure (East US) | $140 (D4s v5) | $280 (D8s v5) | Free (AKS) | 60-90% off |
| GCP (us-central1) | $116 (e2-standard-4) | $233 (e2-standard-8) | $73/mo (GKE Standard)* | 60-91% off |
| DigitalOcean | $96 (Premium, 4 vCPU) | $192 (Premium, 8 vCPU) | Free (DOKS) | Not available |
| Hetzner (Germany) | $19 (CPX41, 8 vCPU/16GB)† | $35 (CPX51, 16 vCPU/32GB)† | Not available (use K3s) | Not available |
| OVHcloud (EU) | $47 (B2-15) | $93 (B2-30) | Free (Managed K8s) | Not available |
Hetzner and OVHcloud offer 3-5x lower pricing than hyperscalers for equivalent compute. The trade-off is a smaller managed service ecosystem and fewer global regions. For compute-heavy workloads with straightforward requirements (web servers, databases, CI/CD runners), European providers deliver exceptional value.
*GKE Standard and Autopilot both charge a $0.10/hour cluster management fee (~$73/month), the same as EKS; GCP waives this for one zonal cluster per billing account, but regional clusters and any additional clusters are billed at the full rate.
†CPX41 and CPX51 actually have double the vCPU count the column header implies at the same RAM tier, so compute-per-dollar is even better than the raw table suggests. Hetzner also raised cloud pricing mid-2026, and the dollar figures above could not be confirmed against a single current source — check Hetzner's own pricing page before relying on them.
Factor 2: Global Infrastructure
| Provider | Regions | Availability Zones | Edge/CDN Locations | Best Coverage |
| AWS | 33 | 105 | 600+ (CloudFront) | Global |
| Azure | 60+ | 190+ | 190+ (Azure CDN) | Global, strong government |
| GCP | 40 | 121 | 187 (Cloud CDN) | Global |
| DigitalOcean | 9 | N/A (single-zone) | N/A | US, EU, Asia-Pacific |
| Hetzner | 5 | N/A | N/A | EU, US (limited) |
| OVHcloud | 15 | 3 AZ regions | N/A | EU, NA, Asia-Pacific |
If your users are global and you need sub-50ms latency worldwide, AWS, Azure, or GCP are the only realistic options. If your users are concentrated in the US and EU, all six providers can serve them effectively.
Factor 3: Managed Services Ecosystem
Managed services reduce operational burden but increase vendor lock-in. The hyperscalers offer 200-300+ managed services; smaller providers focus on the essentials.
| Service Category | AWS | Azure | GCP | DigitalOcean | Hetzner | OVHcloud |
| Managed Kubernetes | EKS | AKS | GKE | DOKS | No (use K3s) | Yes |
| Managed PostgreSQL | RDS | Azure DB | Cloud SQL | Yes | No | Yes |
| Object Storage | S3 | Blob | GCS | Spaces | No (use MinIO) | Yes |
| Serverless | Lambda | Functions | Cloud Functions | Functions | No | No |
| ML/AI Services | SageMaker, Bedrock | Azure AI | Vertex AI | No | No | AI Endpoints |
| Message Queue | SQS, SNS | Service Bus | Pub/Sub | No | No | No |
Factor 4: Developer Experience
Developer experience encompasses CLI tools, documentation quality, API consistency, and community resources. GCP consistently scores highest for documentation and API design. AWS has the largest community and most Stack Overflow answers. DigitalOcean's tutorials library is regarded as one of the best learning resources in the industry.
Factor 5: Compliance and Certifications
Regulated industries (healthcare, finance, government) require specific compliance certifications:
- HIPAA: AWS, Azure, GCP (all three, with BAAs)
- SOC 2 Type II: All six providers
- ISO 27001: All six providers
- FedRAMP: AWS (GovCloud), Azure (Government), GCP (Assured Workloads)
- GDPR: All providers with EU regions. Hetzner and OVHcloud offer EU-only data sovereignty.
For organizations requiring EU data sovereignty under GDPR, Hetzner and OVHcloud are compelling choices because data never leaves EU jurisdiction.
Factor 6: Vendor Lock-in Risk
Lock-in occurs when your application depends on proprietary services that have no equivalent on other providers.
| Lock-in Level | Examples | Mitigation |
| Low | VMs, block storage, object storage (S3-compatible) | Standard APIs, easy migration |
| Medium | Managed Kubernetes, managed databases | K8s is portable; database migration requires downtime |
| High | Lambda, DynamoDB, Azure AD, BigQuery | Proprietary APIs, significant rewrite to migrate |
To minimize lock-in: use Kubernetes for compute orchestration (portable across all providers), S3-compatible object storage (available everywhere), and PostgreSQL for databases (runs on any provider). Avoid deep dependencies on proprietary serverless, message queues, or ML platforms unless the productivity benefit justifies the lock-in risk.
Decision Framework by Organization Type
| Organization Type | Recommended Primary Provider | Why |
| Startup (bootstrapped) | Hetzner or DigitalOcean | Lowest cost, sufficient services |
| Startup (VC-funded) | AWS or GCP | Startup credit programs ($100K+), scalable |
| Mid-market SaaS | AWS or GCP | Broad managed services, multi-region |
| Enterprise | AWS or Azure | Compliance, enterprise support, hybrid cloud |
| EU-regulated | OVHcloud or Hetzner + hyperscaler | Data sovereignty + global reach |
| ML/AI-heavy | GCP or AWS | Best GPU availability and ML services |

Frequently Asked Questions
Should I use multiple cloud providers?
Multi-cloud makes sense when you have specific requirements that different providers serve best (e.g., GCP for BigQuery analytics, AWS for the rest) or when compliance requires data sovereignty in regions only certain providers cover. Multi-cloud for redundancy alone is rarely worth the complexity. A single provider with multi-region deployment provides 99.99% availability at lower operational cost.
How much do cloud startup credit programs offer?
AWS Activate provides up to $100K in credits. Google for Startups offers up to $200K in GCP credits. Azure provides up to $150K through Microsoft for Startups. DigitalOcean's Hatch program offers up to $100K. These programs significantly reduce early-stage cloud costs and are a major factor in provider selection for funded startups.
Is Hetzner reliable enough for production?
Hetzner operates Tier III+ data centers in Germany, Finland, and the US (Ashburn, Hillsboro). Their dedicated servers have 99.9% uptime SLA, and their cloud platform has been in production since 2018. For workloads where the EU-US region footprint is sufficient and you do not need managed services beyond basic compute, networking, and storage, Hetzner is a production-grade option used by companies like Basecamp.
How long does a cloud migration take?
A typical cloud-to-cloud migration for a 20-service application takes 3-6 months. The timeline depends on database size, service coupling, and the degree of proprietary service usage. Applications built on Kubernetes, PostgreSQL, and S3-compatible storage migrate fastest because these technologies work identically across providers.
What is the best provider for Kubernetes?
GKE (Google Cloud) is widely considered the best managed Kubernetes service due to its Autopilot mode, cluster auto-upgrades, and Google's heritage as the creator of Kubernetes. EKS (AWS) has the largest ecosystem but charges $73/month for the control plane. AKS (Azure) is free and integrates well with Azure Active Directory. For cost-optimized K8s, DigitalOcean's DOKS and OVHcloud's Managed Kubernetes are strong options.
