Study Notes
AWS Compute Services Overview
- AWS provides compute services for running applications and workloads, offering flexibility, scalability and efficiency.
Amazon EC2 (Elastic Compute Cloud)
-
EC2 provides virtual servers (instances) for running applications in the cloud.
-
Instance types vary based on needs (CPU, memory, storage).
-
Pricing is pay-as-you-go: pay only for instance usage.
- General Purpose: Balanced for CPU, memory and networking; suitable for web servers (t3, m5 families).
- Compute Optimized: High-performance processors for CPU-intensive tasks (like machine learning) (c5 family).
- Memory Optimized: More memory for large datasets or in-memory databases (r5 family).
- Storage Optimized: Optimized for high-speed or large storage needs (i3 family).
- GPU Instances: Accelerate tasks like deep learning (p3 family).
-
EC2 is best for applications needing full control over virtual machines.
Auto Scaling
- Auto Scaling automatically adjusts the number of EC2 instances based on demand.
- Maintains high availability and saves costs.
- Suitable for fluctuating workloads (like e-commerce during sales).
Elastic Load Balancers (ELB)
-
Load Balancers distribute incoming traffic across multiple servers (e.g., EC2 instances).
-
Keeps applications available and handles large traffic.
- Application Load Balancer (ALB): Works at the application layer (HTTP/HTTPS), routing traffic based on URLs.
- Network Load Balancer (NLB): Works at the network layer (TCP/UDP), ideal for high-performance, low-latency traffic.
- Classic Load Balancer (CLB): A legacy option for basic load balancing.
-
ELBs are crucial for distributing traffic for high availability and performance.
Container Services
-
AWS offers services to manage and deploy containerized applications.
- Amazon ECS (Elastic Container Service): Fully managed container orchestration for Docker containers.
- Amazon EKS (Elastic Kubernetes Service): Managed Kubernetes service for container orchestration (advanced scaling and deployment).
- AWS Fargate: Serverless compute engine for running containers without managing servers.
-
ECS is suitable for simpler container needs, EKS offers advanced Kubernetes management, and Fargate avoids server management.
Serverless Compute
-
AWS serverless compute (no infrastructure management) options:
- AWS Lambda: Executes code in response to events (like HTTP requests), paying only for used compute time.
- AWS Fargate: Runs containers without server management.
-
Lambda is best for event-driven applications, while Fargate handles container workloads without infrastructure management.
Key Differences Between Compute Options
- A summarized comparison of compute services highlighting their key benefits and best use cases. (See table in original text).
Real-World Scenarios
- E-commerce: Use EC2, Auto Scaling, and ELB to handle fluctuating traffic.
- Microservices: Use ECS or EKS for container orchestration.
- Weather App: Use AWS Lambda for hourly scheduled data updates.
Key Takeaways
- Choose EC2 instance types based on workload requirements.
- Auto Scaling adjusts resources automatically.
- Load Balancers distribute traffic efficiently.
- Choose container services (ECS, EKS, Fargate) based on needs.
- Serverless options (Lambda, Fargate) are suitable for applications without infrastructure management.
