Using Containers to Improve Resiliency

Containers have emerged as a game-changing technology in the world of cloud computing, offering a lightweight and efficient way to package and deploy applications. At their core, containers are isolated environments that encapsulate an application and its dependencies, allowing it to run consistently across different computing environments. Unlike traditional virtual machines (VMs), which virtualize the entire hardware stack, containers virtualize at the operating system level, sharing the host’s kernel and reducing overhead. Containers are particularly well-suited for microservices architectures, which we introduced in previous chapters. By breaking down monolithic applications into smaller, independent services, containers enable each service to be developed, deployed, and scaled independently. This modular approach not only improves resiliency by isolating failures to individual services but also facilitates faster development cycles...
