Sep 24, 2019, highlights the paradox of serverless development, where its agility benefits are often hindered by the complexity and time required to test in a cloud environment. The three legs of serverless - service provider, elasticity, and cost - contribute to its power but also present challenges for developers. To overcome these issues, local testing using tools like Docker-lambda, Localstack, and unit tests can be employed, with the goal of eventually moving testing to the cloud when necessary. Eight tips are provided to accelerate this process, including uploading environment resources ahead of time, trimming packages, paying for fast upload speeds, debugging in the cloud, deploying only changes, using S3 transfer acceleration, providing each developer their own development environment, and always using unit testing. By combining these strategies, developers can optimize their serverless development workflow and harness its full potential.
