Cloud Computing Basics — Before Your First Cloud Job

Cloud computing basics you need before your first cloud job

You don't need certifications to break into a cloud role — you need working knowledge of five concepts. Here they are.

1. Compute — the CPU in the cloud

Every cloud has virtual machines: EC2 (AWS), Compute Engine (GCP), Virtual Machines (Azure). Learn to spin one up, SSH in, and deploy a small Python app. Do this once and 40% of cloud interviews become trivial.

2. Storage — where data lives

Object storage (S3, GCS, Blob), block storage (EBS), and databases (RDS, DynamoDB, Firestore). Understand when to use each. Object storage for files, block for VMs, managed databases for structured data.

3. Networking — how things talk

VPCs, subnets, security groups. Learn to think in terms of "which port is open to whom". Most production outages are networking issues in disguise.

4. IAM — who can do what

Access control is the foundation of cloud security. Users, roles, policies, permissions. Get comfortable with the least-privilege principle.

5. Managed services — the real productivity multiplier

Serverless compute (Lambda, Cloud Functions), managed queues (SQS), managed containers (ECS, Cloud Run). These are where startups win. Learning them signals modern cloud fluency.

Certifications — do you need them?

Fresher cloud roles rarely require certs. But a certified fresher gets shortlisted twice as often. Recommended entry certs:

• →AWS Certified Cloud Practitioner (foundational)
• →AWS Solutions Architect Associate (real credibility)
• →Azure AZ-900 or GCP ACE (alternatives)
