Databases on Kubernetes

Denis Souza Rosa

Running stateful applications in containers used to be heavily discouraged. Discover how Kubernetes operators changed the game by acting as automated DBAs for self-healing, zero-downtime database deployments.

#1 about 3 min

Evolution of stateful applications in container environments

Overcoming stateless design limitations enabled modern databases to run effectively inside containers.

#2 about 2 min

Modern improvements driving database adoption in Kubernetes

Performance gains, official vendor images, and separated storage pipelines make containerized databases production-ready.

#3 about 6 min

Extending Kubernetes functionality with custom resource definitions

Custom declarative objects combined with event-based controllers allow continuous supervision of database applications.

#4 about 4 min

Automating database administration via declarative operator patterns

Database-specific operational knowledge encoded in controller applications removes the need for manual administrative interventions.

#5 about 6 min

Deploying a distributed Couchbase cluster via operators

A declarative setup provisions multiple database nodes and replica configurations while connecting securely to external applications.

#6 about 2 min

Reconciling cluster configuration against unauthorized manual changes

Operators treat declarative manifests as the ultimate source of truth by aggressively reverting unauthorized dashboard modifications.

#7 about 4 min

Automating server recovery and cluster data rebalancing

Simulated node failures trigger automated health checks that transparently replace servers and redistribute existing shard data.

#8 about 2 min

Scaling out database compute capacity horizontally during production

Modifying the desired instance count automatically provisions fresh nodes and reallocates workloads without application downtime.

#9 about 6 min

Executing live version upgrades and workload topology tuning

Operators perform rolling deployment updates and allow varied node roles to independently support read or write heavy traffic.

#10 about 4 min

Evaluating data storage modalities for clustered persistent applications

Local persistent disks minimize latency penalties when utilizing database architectures equipped with native replication topologies.

#11 about 6 min

Simplifying database provisioning operations with Kubernetes service brokers

Internal platform catalogs expose preconfigured deployment tiers that abstract complex declarative definitions away from standard developers.

#12 about 4 min

Comparing managed database services against self-hosted Kubernetes operators

Managed cloud solutions reduce operational complexity while self-hosted operator deployments preserve maximum infrastructure customization flexibility.

#13 about 6 min

Exploring cluster scalability limits and data replication topologies

Operator configurations and cross-datacenter replication protect data integrity amidst scaling operational demands.
