### AI overview

This article describes a layered GitOps approach for Kubernetes database platforms: manage infrastructure with Terraform or OpenTofu, manage Kubernetes deployments with Argo CD, and standardize operations for operator-managed databases with ClusterControl. It explains how declarative configuration and drift reconciliation differ between Terraform and Argo CD, and compares infrastructure automation options including Atlantis and Flux tf-controller.

### Source excerpt

Most platform teams already use GitOps for their Kubernetes apps. The config lives in Git, Argo CD applies it, and deployments are predictable. But look one layer down and things get messy. Infrastructure setup is often still done by hand, running Terraform locally or through scattered scripts. Database operations, especially for databases running through Kubernetes [...] The post Implementing GitOps from Infrastructure to DB Operators to Unify Ops for Kubernetes Databases appeared first on Severalnines.

### AI overview

This article explains architectural patterns that combine PostgreSQL and ClickHouse. PostgreSQL serves as the authoritative transactional system for OLTP workloads, while ClickHouse handles large-scale analytical queries and real-time analytics. Continuous Change Data Capture synchronization connects the systems and separates transactional and analytical workloads.

### Source excerpt

The role of databases has shifted significantly as modern applications must deliver real-time analytics, dashboards, and machine learning alongside low-latency transaction processing. Handling these diverse demands with a single relational database has become unsustainable under growing data volumes. Consequently, organizations are adopting specialized database architectures where multiple engines work together based on their strengths, allowing [...] The post Postgres + ClickHouse Architectural Patterns appeared first on Severalnines.
