Google Cloud (GCP)
Pros
- + Best published SLA set in the comparison: 99.99% multi-zone, 99.9% single-instance
- + 43 regions and 130 zones with per-region price variance you can trade against latency
- + Per-second billing and three discount levers — Spot up to 91% off, commitments up to 55–70%
- + Live migration through host maintenance; deep integration with GKE, BigQuery, Vertex AI
- + Real free entry: $300 trial credit that never auto-charges, plus an Always Free e2-micro VM
Cons
- - Poor price-performance for plain VMs versus European VPS specialists; no bundled transfer
- - Egress is expensive ($0.12/GiB Premium) and billed as a separate line item
- - Sustained use discounts don't apply to E2 and N4 — the families entry buyers choose
- - Budgets alert but don't cap Compute Engine spend; human support costs from $29/month
Azure Functions
Pros
- + Permanent free grant of 1 million executions and 400,000 GB-s per month
- + Trigger/binding integrations cover most Azure and third-party services declaratively
- + Durable Functions for stateful orchestration — the strongest workflow story among serverless platforms
- + Hosting plan ladder (Consumption, Flex, Premium, Dedicated, Container Apps) covers most cost/performance points
- + 99.95% SLA with service credits scaling up to 100% below 95% uptime
Cons
- - Cold starts on Consumption hurt latency-sensitive HTTP workloads
- - Per-instance limits (1.5 GB RAM, 1 core) cap what single functions can do
- - Azure surface area: storage account, monitoring, identity, and networking costs stack up
- - Bindings and Durable Functions abstractions lock integration logic to Azure
- - Premium costs real money whether or not traffic flows (EP1 ~$146/month US rates)
