Study Notes

AWS Compute Services

Compute services provide the infrastructure needed to run applications and workloads.
Amazon EC2 (Elastic Compute Cloud): Virtual servers in the cloud.
- Fully customizable (CPU, RAM, storage, etc.)
- Supports various pricing models (on-demand, reserved, spot, savings plans)
- Can be scaled manually or with Auto Scaling
- Use Case: Hosting web applications, databases, and compute-intensive tasks.
AWS Lambda: Serverless compute service.
- Automatically scales with workload
- Pay only for the time code runs (millisecond billing)
- Event-driven (triggered by other AWS services)
- Use Case: Real-time file processing, backend APIs
AWS Elastic Beanstalk: Platform as a Service (PaaS).
- Deploys and manages web applications
- Automatically provisions resources (EC2, S3, RDS)
- Supports various programming languages (Java, Python, Node.js, etc.) for applications
- Simplifies application lifecycle management
- Use Case: Quickly deploying web applications without managing infrastructure.
Amazon ECS (Elastic Container Service): Manages containerized applications.
- Fully managed service
- Works with EC2 and AWS Fargate
- Supports Docker container orchestration
- Use case: Running containerized applications
AWS Fargate: Serverless compute engine for containers.
- No need to manage EC2 instances
- Designed for microservices architectures
- Pay based on consumed CPU and memory resources
AWS Lightsail: Simple cloud service for small projects.
- Bundles compute resources, storage, and networking.
- Pre-configured for applications (WordPress, development stacks, etc.)
- Use Case: Hosting small websites or development environments.

AWS Storage Services

AWS provides storage optimized for different use cases.
Amazon S3 (Simple Storage Service): Object storage.
- Highly scalable and durable (99.999999999% durability)
- Supports various storage classes (Standard, Intelligent-Tiering, Glacier, etc.)
- Use Case: Backups, media storage, or website hosting.
Amazon EBS (Elastic Block Store): Block storage for EC2 instances.
- Persistent and high-performance
- Supports various volume types (General Purpose SSD, Provisioned IOPS SSD for databases, Cold HDD for infrequent access)
- Supports snapshots for backups.
- Use Case: Persistent storage for databases or operating systems.
Amazon EFS (Elastic File System): Managed file storage.
- Scalable file system with multi-AZ availability
- Use Case: Applications needing shared file systems.
Amazon Glacier & S3 Glacier Deep Archive: Cold storage for long-term archiving.
- Low-cost storage for rarely accessed data with various retrieval times.
- Use Case: Compliance data storage or digital archives.
AWS Storage Gateway: Hybrid storage for on-premises environments.
- Interfaces with on-premises systems and AWS storage seamlessly to move data.
- Use Case: Backup and disaster recovery for on-premises environments.

Key AWS Features

Elasticity and Scalability: AWS automatically adjusts resources based on demand to ensure cost efficiency and high availability.
High Availability: Most AWS services provide multi-AZ (Availability Zone) redundancy to ensure uptime.
Security: AWS offers features including IAM for access control and encryption for data at rest and in transit.
Pricing models: AWS provides a variety of pricing models, including on-demand, reserved, and spot instances to suit various needs.
