We are excited to announce Percona Operator for PostgreSQL 2.9.0! In this release, we bring significant improvements across database lifecycle management, security, backup/restore, and operational observability, making it easier than ever to run production PostgreSQL on Kubernetes. Here’s a deep dive into what’s new.   Percona Operator for PostgreSQL 2.9.0 PostgreSQL 18 Is Now the […]

Deploying databases on Kubernetes is getting easier every year. The part that still hurts is making deployments repeatable and predictable across clusters and environments, especially from Continuous Integration(CI) perspective. This is where PR-based automation helps; you can review a plan, validate changes, and only apply after approval, before anything touches your cluster.  If you’ve ever […]

In 2025, the Percona Operator for PostgreSQL put most of its energy into the things that matter when PostgreSQL is running inside real Kubernetes clusters: predictable upgrades, safer backup and restore, clearer observability, and fewer surprises from image and HA version drift.  Backups and restores got more resilient and more controllable In March, Operator 2.6.0 […]

Today, we are sharing an important step forward for the project many of you know as Percona Everest. Percona is transitioning Percona Everest into an independent open source project called OpenEverest (https://openeverest.io/). This change is about one thing: making the project stronger over the long term by building it in the open, with open governance, […]

Over the past few years, we’ve been building Percona Everest with a clear goal in mind: to deliver a powerful yet approachable DBaaS experience on Kubernetes. Thanks to strong user and customer adoption, Everest has grown into a platform with thousands of production clusters deployed and overwhelmingly positive feedback from the community. As adoption grew, […]

As a database administrator, you are the guardian of the company’s most critical asset: its data. You live by performance, reliability, and security, ensuring every change maintains uptime and data integrity. That level of precision takes time, as every update, patch, and configuration is tested before it goes live. Meanwhile, application teams have fully embraced […]

When you went all-in on the cloud, you were promised agility and savings. But sometimes, the reality feels very different. Instead of simplicity and flexibility, you’re facing higher bills, shrinking options, and a single vendor with all the leverage. You’ve just swapped one form of vendor lock-in for another, and this lack of control can […]

Open Source Isn’t What It Used to Be The landscape of open source has undergone significant changes in recent years, and selecting the right operator and tooling for PostgreSQL clusters in Kubernetes has never been more crucial. MinIO, for example, was a widely used open source S3-compatible storage backend. Over the past few years, it has: […]

In 2025, the Percona Operator for MongoDB focused on the hardest parts of running MongoDB in Kubernetes: reliable backups and restores, clearer behavior during elections and restores, better observability at scale, and safer defaults as MongoDB 8.0 became mainstream. The year included real course corrections, such as addressing PBM connection leaks and being explicit about […]

Choosing the right Kubernetes operator is one of those quiet decisions that ultimately defines your database strategy, affecting everything from how easily you automate backups and scaling to how much control you maintain over long-term costs and architecture. But while most operators look similar at first glance, their underlying models yield vastly different outcomes. Some […]
