AWS All-in-one

Amazon Web Services (AWS) is used in Cloud Computing Intro.

Amazon Elastic Compute Cloud: Amazon EC2

Applications are made of multiple components.

For example, there are monolithic applications = an application with tightly coupled components. If one component fails, other components fail.
To help maintain application availability when a single component fails, we can design our application through a microservices approach
- In a microservices approach, application components are loosely coupled.
- Two services facilitate application integration
  - Amazon Simple Notification Service (Amazon SNS): a publish/subscribe service (subscribers can be web servers, email addresses, AWS Lambda functions, etc.)
  - Amazon Simple Queue Service (Amazon SQS): a message queuing service

can be achieved by

your code runs on servers, but you do not need to provision or manage these servers
the flexibility to scale serverless applications automatically
can be achieved by
- ASW Lambda
- AWS Fargate: run your containers on top of a serverless compute platform

AWS Management Console
- a web-based interface for accessing and managing AWS services
AWS Command Line Interface (AWS CLI)
- automate actions for AWS services and applications through scripts
Software development kits (SDKs)
- make it easier for you to use AWS services through an API designed for your programming language or platform.
AWS Management Tools
- AWS Elastic Beanstalk
  - you provide code and configuration settings, and Elastic Beanstalk deploys the resources necessary to perform the following tasks:
    - Adjust capacity
    - Load balancing
    - Automatic scaling
    - Application health monitoring
- AWS CloudFormation
  - treat your infrastructure as code: you can build an environment by writing lines of code instead of using the AWS Management Console to individually provision resources.
  - It determines the right operations to perform when managing your stack and rolls back changes automatically if it detects errors.
- AWS Outposts
  - Extend AWS infrastructure and services to your on-premises data center.
