sidekick

sidekick is a high-performance sidecar load-balancer. By attaching a tiny load balancer as a sidecar to each of the client application processes, you can eliminate the centralized loadbalancer bottleneck and DNS failover management. sidekick automatically avoids sending traffic to the failed servers by checking their health via the readiness API and HTTP error returns.

Case Study: IT Modernization at Tidepool, an 8 part series

https://www.solo.io/blog/case-study-it-modernization-at-tidepool-an-8-part-series

Part 1: Migrating to Kubernetes - https://medium.com/@derrickburns/modernizing-tidepool-part-1-migrating-to-kubernetes-e3361379a3d6 - How they chose cloud hosted Kubernetes, migrating from Docker Compose to Kubernetes and the tools used to help the process.

Part 2: API Gateway - https://medium.com/@derrickburns/modernizing-tidepool-part-2-api-gateway-c6597b160fca - Discusses the required functionality, selection criteria and migration process from a custom solution to Gloo, our Kubernetes native API gateway built with Envoy Proxy.

Part 3: Continuous Delivery with GitOps - https://medium.com/@derrickburns/modernizing-tidepool-part-3-continuous-delivery-with-gitops-5b9c3b20c119 - As a way to manage implementing change to their running services, this article digs how GitOps is different than traditional configuration management and ideal for Kubernetes.

Part 4: Secrets Management - https://medium.com/@derrickburns/modernizing-tidepool-part-4-secrets-management-219db93aa809 - This post specifically addresses how they protect the system secrets that are used to encrypt data or verify identity within the context of their new Kubernetes environment.

Tidepool looked to Linkerd service mesh for mTLS across the intra-cluster communications.

Part 6: Migrating to a Hosted Mongodb - https://medium.com/@derrickburns/modernizing-tidepool-part-6-migrating-to-a-hosted-mongodb-dcd17ecbafb8 - Already a MongoDB user, the modernization initiative had the team take a fresh look at the performance, reliability and operational efficiency of their database as it has grown to over 2B records. This post details the migration from a self-hosted to a managed service from MongoDB.

Part 7: Logging - https://medium.com/@derrickburns/modernizing-tidepool-part-7-logging-aa3c9eff197c - All systems require observation and access to the logs created to understand what’s happening, especially when issues arise that need to be debugged. This post shows how the team has set up their logging systems today, their approach to looking at the right data, and how they are continuing to evolve.

Part 8: Provisioning - https://medium.com/@derrickburns/modernizing-tidepool-part-8-provisioning-6bdbe9519e0a - For anyone running Kubernetes in production or more than one cluster, this post details a provisioning process and available tools that can help with templating.
