Chapter 3: Deep Dive into Compute Services
AWS Compute Services provide a comprehensive toolkit for launching and managing cloud-based applications. It covers essential topics like EC2 instances—including types and pricing models—introduces AWS Lambda for serverless computing, and explains Auto Scaling alongside Elastic Load Balancing (ELB) for maintaining high availability and performance. Together, these services enable efficient resource management to optimize cost and performance.

What we have learnt
- EC2 instances are virtual servers providing full control over configurations and operations.
- AWS Lambda simplifies running code in response to events without server management.
- Auto Scaling and ELB work together to ensure application resilience and cost efficiency.
Key Concepts
- -- EC2 Instance
- A virtual machine within AWS that operates similarly to physical servers allowing users to choose the operating system and configurations.
- -- AWS Lambda
- A serverless compute service that allows the execution of code in response to triggers, facilitating automatic scaling and a pay-per-use billing model.
- -- Auto Scaling
- A service that automatically adjusts the number of EC2 instances in response to demand changes to maintain performance and reduce costs.
- -- Elastic Load Balancing (ELB)
- A service that efficiently distributes incoming traffic across multiple instances to enhance fault tolerance and ensure high availability.
- -- Pricing Models
- Different structures like On-Demand, Reserved, Spot Instances, and Savings Plans that offer varying levels of cost efficiency based on usage commitments.
