Whether you're building a next-gen web app or the next big mobile app, all the sensitive parts of your application (from database access, internal business logic, to even your very large machine learning models) all live in the backend, or the server-side portion of your application.

A long time ago, legacy applications were built to run on a single server, but today's modern cloud-based apps are instead architected via a suite of technologies like container clusters and serverless cloud functions.

Thus, instead of simply balancing load across a group of templated virtual machines (VMs), engineers today are harnessing containerized architectures and microservices to build systems that are easier to manage, more fault-tolerant, more lightweight, and faster to deploy and manage than ever before.
