Infrastructure-as-Code with LocalStack—Building & testing your configurations locally!

Infrastructure-as-Code refers to the practice of defining and provisioning cloud resources using code and automation scripts, thus eliminating the need for manual configurations. With frameworks like AWS CloudFormation, AWS CDK (Cloud Development Kit), AWS Serverless Application Model (SAM), Pulumi, and Terraform, users can specify their desired infrastructure state in code, enabling rapid and consistent deployment of resources.However, as with any code, IaC scripts require thorough testing to ensure their correctness and proper functionality. Traditional cloud environments for testing can be expensive, slow, and error-prone due to complexities in provisioning and configuration. With LocalStack, you can leverage a local emulation of various cloud services, such as S3, DynamoDB, EKS, and more!LocalStack simulates these cloud services on a developer's machine, allowing for comprehensive and efficient testing of IaC scripts before deployment to actual cloud environments. In this video, we explain how you can use LocalStack to be more efficient and cost-effective at testing these major IaC frameworks:• Terraform• Pulumi• Cloud Development Kit• CloudFormation• Serverless Application ModelAs organizations will continue to embrace IaC, cloud emulation framework like LocalStack will play an increasingly vital role in ensuring the quality and robustness of cloud infrastructure implementations.

Accelerate your cloud development with Cloud Pods and LocalStack

Cloud pods are persistent state snapshots of your LocalStack instance that can easily be stored, versioned, shared, and restored. Cloud Pods can be used for various purposes, such as:• Save and manage snapshots of active LocalStack instances.• Share state snapshots with your team to debug collectively.• Automate your testing pipelines by pre-seeding CI environments.• Create reproducible development and testing environments locally.In this session from LocalStack Community Meetup July '24, Bart Szydlowski explores how to use Cloud Pods to accelerate your cloud development & testing. He showcases how you can get started with Cloud Pods, integrate them into your testing pipelines, and make it easy for your team members to be onboarded to your cloud infrastructure — running all on your local machine!Docs: https://docs.localstack.cloud/user-guide/state-management/cloud-pods/

How to use AWS SDKs with LocalStack

LocalStack integrates with official AWS Software Development Kits (SDKs) so you can connect to LocalStack services using the same application code you use for AWS services. This lets you develop and test your applications locally without connecting to the cloud.In this video, we will talk about how you can connect to LocalStack emulated services using AWS SDKs.
