CloudFormation (IaaC):

• Definition: Declarative outline of AWS infrastructure via templates, ensuring repeatability across regions and accounts.

• Stack: Aggregation of AWS resources managed collectively from CloudFormation templates in YAML or JSON

• Benefits:

  • IaaC: Enables control and auditing of changes through code.

  • Cost Management: Utilizes tagging for cost estimation, along with automated cost-saving tactics.

  • Productivity: Facilitates seamless infrastructure creation, destruction, and recreation using pre-existing templates.

• Example: Template-based creation of resources like security groups, EC2 instances, S3 buckets, and load balancers.

---

AWS CDK:

• Definition: Defines cloud infrastructure using common programming languages, compiled into CloudFormation templates.

• Use Cases: Ideal for Lambda functions, Docker containers in ECS/EKS, enabling unified deployment of infrastructure and application runtime.

---

Elastic Beanstalk (PaaS):

• Overview: Developer-centric platform for AWS application deployment, monitoring and performance Management.

• Features:

  • Ease of Use: Simplified interface for deploying applications with known architectures.

  • Managed Service: Handles capacity provisioning, load balancing, auto-scaling, and health monitoring.

  • Architecture Models: Supports single instance deployment, LB + ASG, ASG only, with Docker configurations.

---

Developer Tools

Code Store:

• AWS CodeCommit: Hosts Git-based repositories for version-controlled code collaboration.

• AWS CodeArtifact: Provides secure, scalable artifact management for software development, supporting common dependency management tools.

• Parameter Store: Offers secure storage for configuration and secrets, providing version tracking, encryption, and IAM permissions.

Developer UI

• AWS Cloud9: Cloud-based IDE for writing, running, and debugging code, supporting real-time collaboration.

• AWS CodeStar: Unified UI for managing software development activities, setting up CI/CD pipelines, and code editing in the cloud.

Manage Cloud Systems UI

• AWS Systems Manager (SSM): Hybrid service aiding in managing cloud systems by running commands at scale, offering patching automation, command execution, and parameter storage.

• SSM Session Manager: Facilitates secure shell access to cloud servers without SSH or bastion hosts, supporting session logging.

Deployment Automation

• AWS CodeDeploy: Hybrid service automating application deployment and upgrades onto servers.

• AWS CodeBuild: Serverless Cloud-based service for compiling source code, running tests, and producing deployable artifacts.

• AWS CodePipeline: Orchestrates CI/CD pipelines from code to deployment, supporting various AWS services and third-party integrations.
