AWS - Developer and Deployment
- AWS - Developer and Deployment
Plaform-as-a-Service (PaaS)
-
Plaform-as-a-Service (PaaS)- allows customers to develop, run, and manage application without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.
Deployment Services
AWS Elatic Beanstalk - Paas, Deploy Code, free
-
Elastic Beanstalk-
a PaaS for deploying web-applications with little-to-no knowledge of the underlying infrastucture so developer can focus on writing application code instead of setting up an automated deployment pipeline and DevOps tasks.
-
Choose a platform, upload code, and run with little knowledge of the infrastructure.
-
a developer centric view of deploying an application on AWS
-
-
Beanstalk is free but you pay for the underlying instances
-
Responsibility Model:
- developer
- Just the application code
- AWS
- Instance configuration / OS is handled by Beanstalk
- Deployment strategy is configurable but performed by Elastic Beanstalk
- Capacity provisioning
- Load balancing & auto-scaling
- Application health-monitoring & responsiveness
- developer
-
Three architecture models:
- Single Instance deployment: good for dev
- LB + ASG: great for production or pre-production web applications
- ASG only: great for non-web apps in production (workers, etc..)
-
Support for many platforms
- If not supported, you can write your custom platform (advanced)
- If not supported, you can write your custom platform (advanced)
Elastic Beanstalk – Health Monitoring(CloudWatch)
- Health agent pushes metrics to
CloudWatch - Checks for app health, publishes health events
Elastic Beanstalkcan be used to monitor and to check the health of an environment.
AWS CodeDeploy - Hybrid, app deploy and upgrade
- We want to deploy our application automatically
- Hybrid service
- Works with EC2 Instances
- Works with On-Premises Servers
- Servers / Instances must be provisioned and configured ahead of time with the
CodeDeploy Agent
AWS Systems Manager (SSM) - commands, patch & configure Server, Hybrid
- Helps you manage your EC2 and On-Premises systems at scale
- Another Hybrid AWS service
- Get operational insights about the state of your infrastructure
- Suite of 10+ products
- Most important features are:
- Patching automation for enhanced compliance
- Run commands across an entire fleet of servers
- Store parameter configuration with the SSM Parameter Store
-
Works for Linux, Windows, MacOS, and Raspberry Pi OS (Raspbian)
- We need to install the
SSM agentonto the systems we control - Installed by default on Amazon Linux AMI & some Ubuntu AMI
- If an instance can’t be controlled with SSM, it’s probably an issue with the SSM agent!
- Thanks to the SSM agent, we can run commands, patch & configure our servers
Systems Manager (SSM) Session Manager
- Allows you to start a secure shell on your EC2 and on-premises servers
- No SSH access, bastion hosts, or SSH keys needed
- No port 22 needed (better security)
- Supports Linux, macOS, and Windows
- Send session log data to S3 or
CloudWatch Logs
AWS OpsWorks - as SSM with Chef & Puppet
Chef&Puppethelp you perform server configuration automatically, or repetitive actions- They work great with EC2 & On-Premises VM
AWS OpsWorks= ManagedChef&Puppet- It’s an alternative to AWS SSM
- Only provision standard AWS resources:
- EC2 Instances, Databases, Load Balancers, EBS volumes…
- In the exam: Chef or Puppet needed => AWS OpsWorks
Developer Services
AWS CodeCommit - Code repository
- Developers usually store code in a repository, using the Git technology
- A famous public offering is GitHub, AWS’ competing product is CodeCommit
- CodeCommit:
- Source-control service that hosts Git-based repositories
- Makes it easy to collaborate with others on code
- The code changes are automatically versioned
- Benefits:
- Fully managed
- Scalable & highly available
- Private, Secured, Integrated with AWS
AWS CodeBuild - Compile, serverless
- Code building service in the cloud (name is obvious)
- Compiles source code, run tests, and produces packages that are ready to be deployed (by CodeDeploy for example)
- Benefits:
- Fully managed, serverless
- Continuously scalable & highly available
- Secure
- Pay-as-you-go pricing – only pay for the build time
AWS CodePipeline - Pipline
- Orchestrate the different steps to have the code automatically pushed to production
Code => Build => Test => Provision => Deploy- Basis for CICD (Continuous Integration & Continuous Delivery)
- Benefits:
- Fully managed, compatible with
CodeCommit,CodeBuild,CodeDeploy,Elastic Beanstalk,CloudFormation, GitHub, 3rd-party services (GitHub…) & custom plugins…
- Fully managed, compatible with
- Fast delivery & rapid updates
AWS CodeArtifact - dependencies
artifact management- Storing and retrieving the code dependencies
- Traditionally you need to setup your own artifact management system
- CodeArtifact is a secure, scalable, and cost-effective artifact management for software development
- Works with common dependency management tools such as Maven, Gradle, npm, yarn, twine, pip, and NuGet
- Developers and CodeBuild can then retrieve dependencies straight from CodeArtifact
AWS CodeStar - UI to start a project
- Unified UI to easily manage software development activities in one place
- “Quick way” to get started to correctly set-up CodeCommit, CodePipeline, CodeBuild, CodeDeploy, Elastic Beanstalk, EC2, etc…
- Can edit the code ”in-the-cloud” using
AWS Cloud9
AWS Cloud9 - IDE, pair programming
- AWS Cloud9 is a cloud IDE (Integrated Development Environment) for writing, running and debugging code
- A cloud IDE can be used within a web browser, meaning you can work on your projects from your office, home, or anywhere with internet with no setup necessary
- AWS Cloud9 also allows for code collaboration in real-time (pair programming)
AWS Toolkit for VSCdoe
-
AWS Toolkit- an open-source plugin for VSCode to create, debug, deploy AWS resources.
-
AWS Explorer: Explore a wide range of AWS resources to user’s linked AWS Account. -
AWS CDK Explorer: Allows to explore user’s stacks defined by CDK. -
Amazon Elastic Container Service: Provides IntelliSense for ECS task-definition files. -
Serverless Applications:Create, debug and deploy serverless applications viaSAMandCFN
Summary
-
Developer
Cloud9:- Cloud IDE (Integrated Development Environment) with collab
CodeCommit:- Store code in private git repository (version controlled)
CodeBuild:- Build & test code in AWS
CodeDeploy:- Deploy code onto servers, Hybrid
CodePipeline:- Orchestration of pipeline (from code to build to deploy)
CodeArtifact:- Store software packages / dependencies on AWS
-
CodeStar:- Unified view for allowing developers to do CICD and code

Deployment
CloudFormation: (AWS only)- Infrastructure as Code, works with almost all of AWS resources

- Deploy code consistently with a known architecture: ex, ALB + EC2 + RDS
CodeDeploy(hybrid):- deploy & upgrade any application onto servers
Systems Manager (hybrid):- patch, configure and run commands at scale
-
