Cloud computing has gone from a buzzword to the foundation of modern business infrastructure. Whether a company runs a two-person startup or a global enterprise, it almost certainly relies on cloud services for storage, compute, and delivery. This demand has made cloud skills among the highest-paid and most in-demand in the entire technology sector.

What does a cloud professional actually do?

Cloud roles span a wide spectrum. A Cloud Engineer designs and manages infrastructure — setting up virtual machines, databases, load balancers, and networking rules. A Cloud Architect makes higher-level decisions about which services to use, how to ensure reliability, and how to optimise cost. A DevOps Engineer bridges development and operations, automating deployments and monitoring pipelines. A Cloud Security Specialist ensures data is protected, access is controlled, and compliance requirements are met.

The big three platforms

  • Amazon Web Services (AWS) — the market leader, with the widest range of services and certifications
  • Microsoft Azure — dominant in enterprises already using Microsoft products
  • Google Cloud Platform (GCP) — strong in AI/ML workloads and data analytics

For most beginners, AWS is the safest starting point due to the sheer volume of learning resources, community support, and job listings that specify AWS experience.

Which certification should you pursue first?

The AWS Certified Cloud Practitioner is the recommended entry point. It validates foundational knowledge of cloud concepts, pricing, and core services without requiring deep technical skills. From there, the AWS Solutions Architect Associate is the most recognised and valued certification for cloud engineering roles.

Getting your first cloud job

Certifications open doors, but hands-on experience closes them. Use the AWS Free Tier to build real projects: host a static website on S3, set up an EC2 web server, create a serverless function with Lambda. Document these on GitHub and list them on your CV. Hiring managers consistently say practical evidence beats certifications alone.

Cloud skills compound over time. Every system you build teaches you something the documentation never could. Start with one platform, go deep, and the rest follows naturally.
