Hard blanket recs are hard: Cost of consistency? Maybe a couple of users log out. Self-healing, eventually consistent is the goal. #Data #DataBroker #Raft

Raft is production-ready. Etcd (Kubernetes' storage) and HashiCorp use it. Nomad, Vault, CockroachDB and other modern SQL DBs rely on Raft for consistency across instances. Consistency comes at a cost. #Databases #Raft #DistributedSystems #Etcd #Kubernetes

The database selection meme is generally true - PostgreSQL to fancy solutions back to PostgreSQL. We'll keep supporting Postgres, but we're also exploring new approaches for data storage that go beyond the traditional cycle. #DatabaseArchitecture #DataStorage #systemDesign

Pomerium's data broker storage evolution: Started with cookies, moved to Redis, then PostgreSQL. Now adding file-based storage with clustering and leader election for self-healing, eventually consistent systems. Sometimes the simple solution wins. #DistributedSystems #DataArchitecture #ZeroTrust

Pomerium's IAP architecture: We separate concerns into authentication,proxy & authorization services. Each handles a specific role: login,request forwarding & access control. Our data broker evolved from early cookie-based session storage to coordinate between components. #DataBroker #ZeroTrust #IAP

Flipping the switch doesn’t mean a Kubernetes pod is ready. With Pomerium, it also needs group memberships and policy data before it can serve traffic. Readiness probes make sure pods are truly ready, not just turned on. #Kubernetes #Pomerium #DevOps #CloudNative

Kubernetes uses health probes to keep apps alive. Startup gets things booted, readiness controls traffic, and liveness restarts stuck pods. Self-healing in action. #Kubernetes #DevOps #CloudNative #Containers

Startup probes let your app boot. Readiness probes control traffic. Liveness probes restart it when stuck. Together they keep apps stable. #Kubernetes #DevOps #HealthChecks

Kubernetes health checks prevent bad pods from breaking production by pulling them out of service until they are healthy.
