Kubernetes Sidecar containers, currently still in Beta, are gradually making their way into various deployments and applications. Whether it's logging, monitoring, security, or data synchronization, these containers operate alongside the main application container, enhancing and extending its functionality.

In this post, we'll delve into compelling use cases, detailing straightforward architectural designs.

Redis Cache

For API developers, ensuring optimal responsiveness and minimizing the load on hosting servers are key priorities. To achieve this, many developers choose to implement a cache solution that stores frequently accessed data.

SSO oAuth2 Proxy

To enhance security within Kubernetes environments, safeguarding workloads often involves implementing authentication measures. Additionally, centralizing application access management through Single Sign-On (SSO) becomes crucial, aiming for a unified source of truth for user authentication and authorization.

Legacy Protocol Translation

Oftentimes, maintainers may choose to upgrade their APIs or deprecate certain features, necessitating updates to your application code. In response to these changes, developers might opt to support legacy code intermittently, requiring a software solution that translates between the two versions.

Metrics Exporter (Prometheus)

Maintaining a clear and concise application, free from additional code for observability data, can be challenging. The Sidecar container provides a solution by allowing you to establish a clean separation between these tasks without introducing any additional code to your main application.

Runtime Parameter Loading

Instead of hardcoding values into your application, a sidecar can also function as a component that dynamically loads parameters and e.g. reroutes traffic between microservices to their respective backends.

I hope you find these resources as enlightening as I did. Stay tuned for more exciting developments and updates in the world of cloud computing in next week's newsletter.

Until then, keep innovating and soaring in the cloud! ??
