As a developer, knowing the most famous AWS services and concepts can help you build, deploy, and scale applications efficiently. Here are the must-know AWS points for a developer:
- Compute Services (Running Applications)
✅ EC2 (Elastic Compute Cloud) – Virtual servers for hosting applications
✅ Lambda – Serverless functions for event-driven applications
✅ Elastic Beanstalk – PaaS for deploying web applications
✅ ECS (Elastic Container Service) – Running Docker containers
✅ EKS (Elastic Kubernetes Service) – Managed Kubernetes service
✅ AWS Fargate – Serverless containers without managing EC2
- Storage Services (Data Storage & Retrieval)
✅ S3 (Simple Storage Service) – Object storage with high durability
✅ EBS (Elastic Block Store) – Persistent storage for EC2
✅ EFS (Elastic File System) – Scalable shared storage
✅ Glacier – Long-term data archiving and backup
- Database Services (Storing & Managing Data)
✅ RDS (Relational Database Service) – Managed SQL databases (PostgreSQL, MySQL, Oracle)
✅ DynamoDB – NoSQL key-value store, fully managed
✅ Aurora – High-performance relational database
✅ Redshift – Data warehousing for analytics
✅ ElastiCache – Caching service using Redis/Memcached
- Networking & Security
✅ VPC (Virtual Private Cloud) – Isolated network for resources
✅ Route 53 – Scalable DNS service
✅ IAM (Identity & Access Management) – Users, roles, permissions
✅ AWS WAF (Web Application Firewall) – Protect web applications from attacks
✅ AWS Shield – DDoS protection
- Monitoring & Logging
✅ CloudWatch – Monitor performance, logs, and alerts
✅ CloudTrail – Track API calls and changes
✅ AWS X-Ray – Debugging distributed applications
- CI/CD & DevOps Tools
✅ CodePipeline – Automate CI/CD pipelines
✅ CodeBuild – Continuous integration for building applications
✅ CodeDeploy – Automate deployments across EC2, Lambda, and ECS
✅ GitLab CI/CD on AWS – Popular for automating deployment workflows
- Messaging & Event-Driven Architecture
✅ SQS (Simple Queue Service) – Message queues for decoupled architecture
✅ SNS (Simple Notification Service) – Publish/subscribe notifications
✅ EventBridge – Event-driven application workflow
✅ Step Functions – Serverless workflow orchestration
- AWS Serverless Architecture (Modern Development)
✅ API Gateway – Manage and secure APIs
✅ Lambda – Event-driven serverless functions
✅ DynamoDB – NoSQL for serverless applications
✅ Cognito – Authentication & authorization (OAuth, JWT)
✅ AppSync – GraphQL API service for real-time apps
- Cost Optimization & Scalability
✅ Auto Scaling Groups – Automatically scale EC2 instances
✅ AWS Savings Plans & Reserved Instances – Reduce cloud costs
✅ AWS Cost Explorer – Analyze and manage costs
✅ Spot Instances – Cheap compute power for batch jobs
- Advanced Topics
✅ AWS Well-Architected Framework – Best practices for security, performance, and cost
✅ AWS CDK (Cloud Development Kit) – Infrastructure as Code with TypeScript/Python
✅ CloudFormation – Automate infrastructure deployment
