Upcoming Events
Join LocalStack at Booth B14 during AWS Summit London 2026.
What you'll discover: Learn how building and testing your AWS applications locally with LocalStack can significantly increase delivery speed, reduce cloud risk, and lower costs for your teams.
Featured Demonstration: We will be showcasing the local deployment and validation of a complete event-driven serverless quiz application built with AWS services. See firsthand how LocalStack features accelerate your development cycle, providing faster feedback and greater confidence before you deploy to AWS.
Event Details:
- Where: ExCeL London, Royal Victoria Dock, 1 Western Gateway, London E16 1XL, UK
- When: Wednesday, 22 April 2026, approximately 08:00–18:00 BST
- Find Us: Bronze Sponsor, Booth B14
So many of the challenges that slow down software development stem from the fact that early-stage dev & test cycles are performed in cloud environments.
Local cloud development removes these challenges.
By simulating AWS application behavior in a local container, the local cloud enables developers and agents to validate the security, quality, and reliability of their applications faster and more effectively than they can on the cloud.
Join us on Wednesday, May 6, for a live demo to learn how our users:
- Eliminate access restrictions, provisioning delays, and cloud costs for low-level AWS environments
- Accelerate CI/CD pipelines by providing a local endpoint for testing stages
- Streamline security validation, debugging, and resiliency testing with unique features that can’t be replicated on the cloud
- Ship code to production seamlessly to integrate the local cloud into day-to-day development workflows
Join our April meetup where John Nguyen from E.ON demonstrates how Testcontainers and LocalStack let you run integration tests against realistic AWS services locally. He'll walk through the pitfalls of mock-based testing and show how spinning up real services in Docker containers gives you confidence that your code actually works against emulated services. This session will give you practical techniques for writing integration tests that catch the bugs your unit tests miss.

The challenge with Machine Learning (ML) models is productionizing. It requires data ingestion, data preparation, model training, model deployment, and monitoring.Adopting MLOps practices is similar to DevOps practices. In MLOps, the workload changes, but some core principles like automation, continuous integration/continuous deployment (CI/CD), and monitoring. Taking DevOps practices, I will discuss the similarities and differences in adopting MLOps practices.In this talk, Chinmay takes a production use case to scale ML models to 2 million+ daily requests. It leverages Google Cloud's (GCP) infrastructure to use its GPU and other services. This talk will help you draw similarities between DevOps and MLOps as a DevOps practitioner and help you learn how to run Machine Learning models at the production scale with best practices.
Creating data pipelines and applications for the cloud comes with challenges like a complicated developer experience, dealing with managed cloud dependencies, and enduring long build times. These issues often disrupt your development and testing cycles.LocalStack's cloud emulation allows you to construct, deploy, and test data pipelines on your local machine. It facilitates integration testing of cloud solutions both locally and in CI pipelines. This approach saves time and money, enhances developer velocity, and supports high-quality, agile, test-driven development.In this talk, Harsh delves into developing and testing cloud-based data pipelines on your local machine. The session will provide a firsthand look at the new Snowflake emulator and demonstrate how you can use LocalStack to create Snowflake warehouses, databases, schemas, and tables, and integrate frameworks like Snowpark.
With the growing Serverless workloads, managing and maintaining them is best recommended with Infrastructure as Code (IaC). While this holds the complete infrastructure and its configurations, we could have events from one service destined to another via configuration. When building these configurations, we could also reduce the application code making it more maintainable and scalable.In this session, Jones walked us through a fully end-to-end solution built with Amazon EventBridge and AWS Step Functions with SDK integrations which have helped him to improvise the application with just IaC and very minimal application code.
Connecting your applications to LocalStack has not always been easy. In this video, Simon from the LocalStack team discusses how we streamlined the LocalStack networking experience. We discussed the challenges of connecting your applications to LocalStack and how we're simplifying the LocalStack networking experience.Simon also discussed about configurations required for more complex networking setups, and some common networking scenarios, with example configuration for achieving connectivity.Read our blog to learn more: https://blog.localstack.cloud/2024-03-04-making-connecting-to-localstack-easier/
Check out the recording of the hands-on webinar featuring Yan Cui, AWS Serverless Hero, and Waldemar Hummer, CTO of LocalStack, to learn practical use cases around monitoring serverless applications for local dev&test loops. Learn the best practices for debugging serverless applications using various AWS services to support your serverless workflows while troubleshooting errors and performance issues.In this video, you will learn about:- Building and Deploying Serverless apps locally- Common patterns and workflows for testing Serverless apps- Troubleshoot errors and performance issues in dev&test loops- Implementing observability with distributed tracing with Lumigo- Local Serverless Development with LocalStack
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!
