Microsoft Azure
Pros
- + Deep Microsoft integration: Entra ID, Windows Server/SQL licensing (Hybrid Benefit), Azure Arc hybrid management
- + Tiered availability SLA up to 99.99% across availability zones, with credits up to 100% below 95%
- + Free tier of 750 hours/month for 12 months on B1s, B2pts v2, and B2ats v2 VMs
- + Massive global footprint with EU/US/APAC residency and sovereign clouds
- + Full SKU ladder including N-series GPUs and Arm-based options
Cons
- - List-price price-performance is several times worse than value VPS providers
- - Disks, public IPs, egress, backup, and monitoring all meter separately from the VM
- - Dense portal and vocabulary — real onboarding time for small teams
- - Conditional SLAs: 95% for a single VM on Standard HDD; 99.99% only with your own multi-zone design
- - Production-grade support is a paid tier
Cloudflare Workers
Pros
- + No cold starts: V8 isolates start in microseconds at 330+ locations
- + CPU-time billing with a genuinely usable free tier (100k requests/day)
- + No egress or bandwidth charges on any plan
- + Storage stack (KV, D1, Durable Objects, R2) binds declaratively and stays in-network
- + Strong docs: pricing and limits pages are explicit and example-driven
Cons
- - CPU time caps exclude compute-heavy and long-running workloads
- - Real vendor lock-in through Durable Objects, bindings and deployment model
- - KV writes ($5.00/M) and Durable Objects duration billing surprise stateful designs
- - Conceptual shift for teams used to container-based serverless
- - No uptime SLA below the Business plan
