What is AWS and how are its services structured?
AWS is a cloud platform offering a wide range of services organised into categories such as:
• Compute
• Storage
• Database
• Networking & Content Delivery
• Security
• Management & Governance
👉 Services act as building blocks to create scalable cloud solutions
What are the main categories of AWS services?
• Compute
• Storage
• Database
• Networking & Content Delivery
• Security, Identity & Compliance
• Management & Governance
👉 Each category contains specialised services for different use cases
Explain AWS Compute services and give key examples.
Compute services provide processing power:
• Amazon EC2 – virtual servers (full control)
• AWS Lambda – serverless execution
• Elastic Beanstalk – deploy apps without managing infrastructure
👉 Used for running applications and workloads
Differentiate EC2, Lambda, and Elastic Beanstalk.
• EC2: Full control, manage OS and infrastructure
• Lambda: No server management, event-driven
• Beanstalk: Platform-managed deployment
👉 Control ↓ → Automation ↑ (EC2 → Beanstalk → Lambda)
What are AWS Storage services and their use cases?
• Amazon S3: Object storage (scalable, durable)
• Amazon EBS: Block storage for EC2
• Amazon EFS: Shared file storage
👉 Used depending on access type (object, block, file)
Compare S3, EBS, and EFS.
• S3:
Object storage
Internet-accessible
Highly scalable
• EBS:
Block storage
Attached to EC2
High performance
• EFS:
File storage
Shared across multiple EC2 instances
👉 Choose based on data structure + access pattern
What are AWS Database services and when are they used?
• Amazon RDS: Managed relational database
• Amazon DynamoDB: NoSQL database
• Amazon Redshift: Data warehouse for analytics
👉 Used for structured, unstructured, and analytical workloads
What are AWS Networking & Content Delivery services?
• Amazon VPC: Virtual network
• Elastic Load Balancer: Distributes traffic
• Amazon CloudFront: Content delivery (CDN)
• Amazon Route 53: DNS service
👉 Enables connectivity, routing, and global delivery
What are AWS Security and Identity services?
• AWS IAM: Access control (users, roles, policies)
• AWS Shield: DDoS protection
• AWS WAF: Web application firewall
👉 Protect systems, data, and access
What are AWS Management & Governance services?
• Amazon CloudWatch: Monitoring and metrics
• AWS CloudTrail: Tracks API activity
• AWS Config: Resource configuration tracking
👉 Helps manage, monitor, and audit AWS environments
