AWS Cloud Practitioner With Neel

AWS Software Development Kit (SDK)

AWS SDK is a collection of software development tools provided by Amazon Web Services (AWS) that simplifies the process of interacting with AWS resources programmatically. With AWS SDK, developers can create, modify, delete, and manage AWS resources through various programming languages.

Available SDKs

AWS SDK is available for several programming languages, including:

  • Java

  • Python

  • Node.js

  • Ruby

  • Go

  • .NET

  • PHP

  • JavaScript

  • C++

These SDKs help developers integrate AWS services into their applications with ease.

AWS CloudShell

AWS CloudShell is a browser-based shell integrated into the AWS Management Console. It offers a ready-to-use environment for managing AWS resources and executing scripts.

Key Features

  • Free Service: AWS CloudShell is available at no additional cost.

  • Preinstalled Tools: Includes AWS CLI, Python, Node.js, Git, Make, Pip, Sudo, Tar, Tmux, Vim, Wget, and Zip, among others.

  • Storage Included: 1 GB of storage per AWS region.

  • Shell Environments: Supports switching between Bash, PowerShell, and Zsh.

  • Saved Files and Settings: Files saved in your home directory persist across sessions within the same AWS region.

Infrastructure as Code (IaC)

Infrastructure as Code (IaC) is a methodology where you write scripts to automate the creation, updating, or destruction of cloud infrastructure. IaC allows for better management, version control, and sharing of infrastructure configurations.

AWS IaC Offerings

AWS CloudFormation (CFN)

  • Declarative IaC Tool: Specifies what resources are needed and AWS CloudFormation handles the configuration.

  • Declarative: More verbose but ensures configurations are explicitly defined, reducing the risk of misconfiguration.

  • Configuration Languages: Supports JSON, YAML, and XML.

AWS Cloud Development Kit (CDK)

  • Imperative IaC Tool: Allows you to write infrastructure code using familiar programming languages.

  • Imperative: Specifies what actions to perform, with less verbosity but potential for misconfiguration.

  • Integration with CloudFormation: CDK generates CloudFormation templates.

  • Features:

    • CDK Constructs: A large library of reusable cloud components (Constructs).

    • CLI Tools: Includes its own CLI and CDK Pipelines for CI/CD.

    • Testing Framework: Provides frameworks for Unit and Integration Testing.

CloudFormation vs. CDK

  • CloudFormation: Simple and straightforward, but can result in large files. Easier for those without a programming background.

  • CDK: Offers more flexibility and dynamic configurations. Generates CloudFormation templates but requires understanding of both tools for debugging.

AWS Toolkit for VSCode

AWS Toolkit for VSCode enhances the development experience by integrating AWS features directly into the VSCode IDE.

Features

  • AWS Explorer: Explore various AWS resources in your linked AWS account.

  • AWS CDK Explorer: View and manage CDK-defined stacks.

  • Amazon Elastic Container Service (ECS) IntelliSense: Provides IntelliSense for ECS task definitions.

  • Serverless Application Support: Create, debug, and deploy serverless applications via SAM and CloudFormation.

Access Keys

Access Keys are credentials required for programmatic access to AWS resources outside the AWS Management Console.

Key Points

  • Commonly Referred to as AWS Credentials: Includes an access key ID and a secret access key.

  • Access Management: Users must be granted permissions to use access keys.

  • Security Best Practices:

    • Never share access keys.

    • Avoid committing access keys to codebases.

    • You can have up to two active access keys and deactivate them if necessary.

  • Access Rights: Access keys have the same permissions as the user associated with them.

AWS Documentation

AWS Documentation is a crucial resource for understanding AWS services and preparing for AWS certifications. AWS provides detailed documentation for each service, which forms the basis for learning and practical application.
