Continuous Delivery Patterns with Serverless Applications

Adoption of serverless technology is on the rise, with companies like CloudZero, a Semaphore customer, sharing their experiences in achieving continuous delivery in serverless environments. Serverless computing eliminates the need to manage or scale servers, focusing instead on deploying functions and configuring managed services and infrastructure. This shift requires new tools and practices for optimal developer productivity, such as replicating cloud conditions in development environments, using deployment frameworks like the Serverless framework or AWS SAM, securely storing cloud keys, and maintaining automated testing as a core part of the workflow. CloudZero emphasizes the importance of being able to quickly deploy to production, using polyglot programming languages to suit different needs, and keeping code validation separate from delivery. Semaphore supports these processes by offering tools for managing secrets, providing a fast CI environment, and allowing flexible deployment configurations, which are essential for managing diverse technology stacks and development workflows.
