Summary and Quiz

Let’s look at some key takeaways from this section and then we’ll put our learnings to a test by attempting a quiz.

Summary

• S3 bucket: An S3 bucket is a fundamental storage unit in Amazon S3. It is essentially a container for storing and organizing objects (files or data) within the S3 storage system.

• S3 object storage classes: S3 offers various storage classes with variable costs and retrieval times. These storage classes can be categorized among four major access tiers.

  • Frequent access: The S3 Standard class has the lowest access latency and highest cost, so it is used for the most frequently accessed objects.

  • Infrequent access: S3 offers S3 Standard-IA and S3 Standard One Zone Express IA for infrequently accessed objects.

  • Archive: S3 offers three storage classes for archival purposes: S3 Glacier Flexible Retrieval, S3 Glacier Instant Retrieval, and S3 Glacier Deep Archive. These storage classes vary in cost and the time required to restore the object.

  • S3 Intelligent-Tiering: This storage class automates the transition of objects between multiple storage classes based on the access pattern.

• AWS Lambda: AWS Lambda is a FaaS, serverless computing service that allows us to run code without provisioning or managing servers. It is invoked by an Event, which triggers the Lambda function to launch an execution environment containing memory and RAM and execute the code.

• Virtual Private Cloud (VPC): This is the foundation of AWS infrastructure, providing isolated, secure, and customizable cloud spaces. AWS creates a default VPC in each Region, pre-configured with default subnets, route tables, internet gateways, and security settings, simplifying resource launch. However, we can launch custom VPCs and subnets.

• Amazon Elastic Container Service (ECS): AWS offers a fully managed container orchestration service that simplifies the deployment and management of containerized applications, allowing us to run Docker containers at scale.

• Amazon Elastic Kubernetes Service (EKS): This is a fully managed container orchestration service that simplifies managing Kubernetes clusters on AWS. EKS manages clusters with a control plane hosted in an AWS-managed VPC and worker nodes in a customer-managed VPC.
