Cloud for DevOps (2026) - Which to Learn & the Fundamentals

DevOps runs on the cloud. This guide helps you pick a platform to start with, then covers the two cloud fundamentals every DevOps engineer is expected to know: networking and identity/access.

Which cloud is best for DevOps jobs in India?

AWS dominates DevOps job demand in India and globally - it is the safest first choice.

Is Azure useful?

Yes. Azure is strong in enterprises built on Microsoft and .NET, and in many GCCs.

What about GCP?

GCP is popular with data, analytics and AI-focused companies, and for Kubernetes (it created the technology behind it).

Beginner recommendation

Start deep on AWS, learn the concepts well, then expand to a second cloud later - the fundamentals transfer across all three.

Cloud networking basics

Every cloud gives you a private network (a VPC on AWS) divided into subnets (public and private). Security groups and firewall rules control which traffic is allowed in and out, route tables decide where traffic goes, and load balancers spread traffic across servers. Understanding this is what lets you deploy applications that are both reachable and secure.

IAM and access control

Identity and Access Management (IAM) controls who can do what in your cloud account. The golden rule is least privilege - grant only the permissions a user or service actually needs. Key building blocks are users, groups, roles (assumed by services), and policies (the JSON that defines permissions). Mishandled IAM is one of the biggest causes of cloud breaches, so DevOps engineers are expected to get this right.

Bottom line

Pick AWS first, master networking and IAM early, and the rest of the cloud becomes far easier to learn.
