In this blog post, the author shares the story of Andy Gonzalez, an SRE team leader who used Dagger to speed up his production AWS Lambda deployments from a few hours to just a few minutes, achieving a 93% reduction in processing time. Previously, deploying Lambdas was a manual and time-consuming process that took between 1-3 hours every time, with challenges including complex YAML files and a lack of automation. Andy replaced this process with Dagger, which enabled him to deploy Lambdas in parallel using matrix jobs, significantly speeding up the deployment process. The new approach also encapsulated deployment business logic within Dagger pipelines, making it easier to test and maintain. Going forward, Andy plans to combine his existing CircleCI pipeline with Dagger and migrate the CircleCI pipeline to Dagger, expecting this will make the deployment process even more efficient.
