In this article, we'll explore how you can quickly and easily leverage the Less Key-Value Store feature (backed by AWS DynamoDB) to set up caching for a REST API. We will explore different strategies for cache invalidation and updates including time-based invalidation using TTL, manual invalidation, and write-through cache.

Less was built to allow a very small number of Senior Engineers and Architects to leverage large teams of Junior Engineers to quickly and reliably iterate and deliver advanced software systems.

In this article we will build the same REST API using both Terraform and Less, demonstrating how much faster, easier, and more reliable it is to achieve the same result with Less.

Less is an easy to use framework that automates the creation and deployment of your serverless applications to the cloud (AWS, Google Cloud, and Azure). Write essentially the same Javascript, Python, Go, or Rust code that you are already accustomed to and Less handles the rest. You'll forget the cloud is there!

In this article I will use Less to demonstrate how to build and deploy a Food Delivery system to AWS using the Choreography Coordination Microservices Pattern. Join me to learn how Less makes complex, fault tolerant, event-driven microservices easily accessible to Engineers of all experience levels with no DevOps.

Implementation is in Javascript with Python, Go, and Rust examples coming soon.
