What is the market share of GCP vs Azure?
As of 2026, global IaaS+PaaS share is AWS 30%, Azure 25%, and GCP 12%. In Japan, Azure has higher adoption thanks to Microsoft 365, while GCP is growing rapidly on the back of its AI and data strengths.
Which is cheaper: Compute Engine or Azure VM?
Roughly equivalent. GCE applies a Sustained Use Discount automatically, while Azure relies on Reserved Instances plus the Hybrid Benefit for Windows and SQL Server.
BigQuery or Azure Synapse: which should I choose?
Choose BigQuery if you want a serverless warehouse with Gemini integration. Choose Synapse / Fabric if Microsoft Fabric or Power BI integration matters. Since 2024, GCP has been strengthening BigQuery + Looker integration to counter Fabric.
What is the difference between Cloud Run and Container Apps?
Both are Knative-based serverless container platforms with similar features. Cloud Run has a simpler UX and faster cold starts; Container Apps stands out with Dapr integration and built-in KEDA support.
Should I use Gemini or Azure OpenAI?
If you must have the GPT-4 family, Azure OpenAI is the only choice; otherwise Gemini is cheaper. Gemini dominates for multimodal video. For code generation, Claude Sonnet 4 is currently the strongest, and Vertex AI lets you access both.
How do they compare on identity and SSO?
Entra ID (formerly Azure AD) dominates thanks to M365 and Windows AD integration; GCP Cloud Identity is still catching up. For hybrid identity, Azure-centric designs are usually more practical.
What about hybrid cloud support?
Azure leads with Azure Arc and Azure Stack. GCP counters with GKE Enterprise (formerly Anthos). Multicloud management is roughly a tie.
Which has easier-to-earn certifications?
Azure has 50+ exams; AZ-900 (Fundamentals) is the entry point at $165. GCP has 15 exams; CDL (Foundational) is $99. Azure is more granular with more exams; GCP keeps things simpler.
