Study Notes

Elastic Container Registry(ECR)

ECR is a private Docker registry on AWS
It allows you to store Docker images for use with ECS or Fargate

Serverless

Serverless is a new paradigm that allows developers to deploy code and functions without managing servers
Initially, serverless was synonymous with FaaS (Function as a Service)
AWS Lambda pioneered the serverless concept
Serverless includes managed services like databases, messaging, and storage
Serverless doesn't mean there are no servers, but rather that you don't manage, provision, or see them

AWS Lambda

AWS Lambda is a serverless compute service
It runs functions on demand, scaling automatically
Lambda offers high performance optimized for specific data models
Lambda functions have short execution times (limited by time)
Lambda functions have limited resources: RAM and CPU
Lambda is more flexible and scalable than Amazon EC2

NoSQL Data Example: JSON

JSON is a common form of data used in NoSQL models
JSON data is structured as nested key-value pairs
NoSQL databases can handle arrays and new types

Databases and Shared Responsibility on AWS

AWS offers managed database services with benefits like quick provisioning, high availability, scaling, automated backup and restore, and operating system patching
AWS manages patching, backup, and high availability for managed databases
Running databases on EC2 requires manual management for these features

AWS RDS Overview

RDS stands for Relational Database Service
It is a managed database service for SQL databases
RDS includes features like monitoring, alerting, and integration with other AWS services

Amazon QuickSight

QuickSight is a serverless business intelligence service powered by machine learning
It enables users to create interactive dashboards and perform ad-hoc analysis
QuickSight is fast, scalable, embeddable, and priced per session
It integrates with various AWS services like RDS, Athena, Redshift, and S3

DocumentDB

DocumentDB is a managed NoSQL database service for MongoDB
DocumentDB allows you to store, query, and index JSON data
It offers high availability with replication across three availability zones
As a managed database service, DocumentDB provides automated backup and restore

Other Compute Options

Docker: Container technology for running applications
ECS: Runs Docker containers on EC2 instances
Fargate: Serverless offering for running Docker containers without provisioning infrastructure
ECR: Private Docker image repository
Batch: Runs batch jobs on managed EC2 instances
Lightsail: Predictable and low pricing for simple applications and database stacks

Lambda Summary

Lambda is a serverless, Function-as-a-Service solution with seamless scaling and reactive execution
Lambda billing is based on the execution time, RAM provisioned, and number of invocations
Lambda supports various programming languages but not arbitrary Docker containers
Lambda functions have a maximum execution time of 15 minutes
Lambda can be used for various use cases like creating image thumbnails or running serverless cron jobs
API Gateway allows developers to expose Lambda functions as HTTP APIs

CloudFormation

CloudFormation is a declarative way to outline AWS infrastructure
It provides a consistent method for defining infrastructure across applications and environments

AWS Elastic Beanstalk

Elastic Beanstalk offers a developer-centric approach to deploying applications on AWS
It simplifies managing EC2, ASG, ELB, RDS, and other services
Elastic Beanstalk is considered a Platform-as-a-Service (PaaS)
It is free, but users pay for underlying instances

Elastic Beanstalk Features

Elastic Beanstalk manages instance configuration, operating system, deployment strategy, capacity provisioning, load balancing, auto-scaling, and application health monitoring
Developers are responsible for application code only
Elastic Beanstalk supports different architecture models like single instance deployment, LB + ASG, and ASG only

Elastic Beanstalk Supported Platforms

Elastic Beanstalk supports various platforms including Go, Java SE, Java with Tomcat, .NET on Windows Server with IIS, Node.js, PHP, Python, Ruby, and Docker
It allows users to create custom platforms for unsupported platforms

Elastic Beanstalk Health Monitoring

A health agent pushes metrics to CloudWatch
It monitors application health and publishes health events

AWS CodeDeploy

CodeDeploy automatically deploys applications to EC2 instances and on-premises servers
Servers need to be provisioned and configured with CodeDeploy Agent
CodeDeploy works in a hybrid environment, supporting both cloud and on-premises deployments

AWS CodeCommit

CodeCommit is a source control service that hosts Git repositories
It facilitates code collaboration and automatic versioning
CodeCommit is fully managed, scalable, highly available, private, secure, and integrated with AWS

AWS CodeBuild

CodeBuild is a cloud-based code building service
It compiles source code, runs tests, and produces ready-to-deploy packages
CodeBuild is fully managed, scalable, highly available, secure, and offers pay-as-you-go pricing

AWS CodePipeline

CodePipeline orchestrates code deployment through a series of steps: Code, Build, Test, Provision, and Deploy
It forms the basis for Continuous Integration and Continuous Delivery (CI/CD)
CodePipeline integrates with CodeCommit, CodeBuild, CodeDeploy, Elastic Beanstalk, CloudFormation, GitHub, and third-party services

AWS CodeArtifact

CodeArtifact provides artifact management for software packages
It allows users to store and retrieve code dependencies
CodeArtifact is secure, scalable, cost-effective, and supports common tools like Maven, Gradle, and npm

AWS CodeStar

CodeStar offers a unified interface for managing software development activities
It simplifies setting up CodeCommit, CodePipeline, CodeBuild, CodeDeploy, Elastic Beanstalk, EC2, and other services
CodeStar allows developers to edit code in the cloud using AWS Cloud9

AWS Cloud9

Cloud9 is a cloud-based integrated development environment (IDE)
It allows users to write, run, and debug code within a web browser
Cloud9 supports collaboration in real-time (pair programming)

AWS Systems Manager (SSM)

SSM manages EC2 and on-premises systems at scale
It provides operational insights into infrastructure health
SSM offers a suite of products, including patching automation, remote command execution, and parameter configuration storage
SSM supports both Windows and Linux operating systems

How Systems Manager Works

SSM agent needs to be installed on managed systems
The agent is installed by default on Amazon Linux AMI and some Ubuntu AMIs
SSM agent issues can prevent system management via SSM
