Local development and testing are significant for engineers who wish to ship confidently onto production environments. Test-driven development (TDD) has been adopted as an essential practice to enforce that and ensure that every code change is validated locally and on CI. This is where we arrive at the Testcontainers libraries that support your tests, providing lightweight, ephemeral instances of common databases, message brokers, web browsers, or anything else that can run in a Docker container. With Testcontainers, available in different popular languages: Java, Go, .NET, JavaScript/Typescript, and Python, you can replicate the production environment on your local machine and test everything (including AWS APIs powered by LocalStack)! Testcontainers ensure that the data access layer, user interface, and application are tested well at each step. In this session, we have looked at Testcontainers and how to adopt them to develop our applications locally and run our integration tests while using LocalStack to provision cloud resources inside a Docker container before pushing your application to production! In the end, we have also discussed how LocalStack and the Java version of Testcontainers play nicely with each other and wind up with updates about the all-new LocalStack release!

Get started with LocalStack in minutes! In this episode, we’ll clone a ready-to-go AWS sample app, spin up LocalStack, and run everything locally without a cloud account. By the end, you’ll have a fully functional event-driven app running on your machine.📖 Want more?Check out the companion blog post for a deeper breakdown of the architecture, project structure, and all the commands you’ll need to run it yourself.🔗 https://blog.localstack.cloud/why-i-run-my-serverless-apps-locally/

Bedrock is a fully managed service provided by Amazon Web Services (AWS) that makes foundation models from various LLM providers accessible via an API. LocalStack allows you to use the Bedrock APIs to test and develop AI-powered applications in your local environment.In this video, Silvio showcases how LocalStack 4.0, with our new Bedrock support, is keeping up with advancements in Generative AI (GenAI) and large language Model (LLM) ecosystems. You'll learn what Amazon Bedrock is, the benefits of Bedrock emulation, and a live demo of how it works.## Resources- Documentation: https://docs.localstack.cloud/user-guide/aws/bedrock/- Get access: https://www.localstack.cloud/contact

LocalStack's core cloud emulator lets you emulate various cloud services on your own computer. This means you can develop and test your cloud-based solutions without connecting to a remote cloud.However, there are times when you need to seamlessly switch between your local setup and actual cloud resources, especially in hybrid situations. For instance, you might want to share a database with your local Lambda function or access S3 files stored remotely while running a Glue ETL job locally.With LocalStack's AWS Replicator extension, your local environment can replicate AWS cloud resources at the API level, allowing direct interaction with cloud services. The Replicator extension enables you to forward specific requests from LocalStack to AWS without complex proxy setups, and create test scenarios that involve a mix of local and cloud resources.Check out our tutorial — https://docs.localstack.cloud/tutorials/replicate-aws-resources-localstack-extension/
