AWS Lambda is rated higher (4.1 vs 3.6). Microsoft claims over 95% of Fortune 500 use Azure (vendor claim, unverified) AWS Lambda is the original FaaS service — run code without servers. Supports 15+ runtimes, 1M free requests/month, and integrates deeply with 200+ AWS services. Triggered by S3, DynamoDB, API Gateway, and more.

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
AWS Lambda
Pros
- + Zero idle cost with a free tier that covers small products: 1M requests and 400,000 GB-seconds monthly
- + Graviton pricing at $0.0000133334 per GB-second undercuts x86 by roughly 20%
- + Automatic multi-AZ scaling with a 99.95% per-region SLA and no capacity planning
- + Deep event integration across AWS services, with three form factors (Event/Web Functions, MicroVMs)
Cons
- - Per-request and GB-second pricing gets expensive against committed compute at steady high utilization
- - Cold starts — hundreds of milliseconds to seconds depending on runtime — with provisioned concurrency as an extra meter
- - 15-minute execution limit and payload caps make it wrong for long-running batch work
- - AWS-specific event plumbing creates real lock-in; distributed event chains are hard to debug
