LocalStack is the leading cloud development platform to enable you to develop and test your cloud & serverless applications locally.
Shared staging: where one team's test run quietly breaks another's. ECI Research on LocalStack for Azure: a single-tenant sandbox per developer, no cloud credentials, and your existing Bicep or Terraform as-is. What's your worst shared-staging story?
We're running a hands-on workshop with the AWS Connected Community. You'll build a coffee-ordering serverless web application and work through event-driven architecture patterns along the way. Register and join us tomorrow! aws-experience.com/amer/smb/e/4...
Serverlesspresso: Building a Scalable and Secure Retail Application with LocalStack
