Sergey ProninThis post was originally published in 2023, and we’ve updated it in 2025 for clarity and relevance. Downtime is more than an inconvenience. For many organizations, even a short outage can mean lost revenue, broken customer trust, or compliance issues. PostgreSQL is a cornerstone for critical applications, and disaster recovery (DR) is essential when running […]
This blog was originally published in 2021 and updated in 2025. Running PostgreSQL in production means balancing high availability, disaster recovery, and scalability without adding unnecessary complexity. Kubernetes helps by providing a consistent way to orchestrate these needs, and with the Percona Operator for PostgreSQL, you can deploy and manage enterprise-ready clusters with minimal manual […]
This post was originally published in 2022, and we’ve updated it in 2025 for clarity and relevance. PostgreSQL was initially released in 1996, when cloud-native was not even a term. According to DB engines, it is currently the fourth most popular relational open source database. With its popularity growing and the rising trend of Kubernetes, […]
This post was originally published in 2021 and was updated in 2025. Kubernetes adoption keeps climbing, and databases are often one of the last workloads teams try to move. The reasons are clear: PostgreSQL is critical, downtime isn’t an option, and migration can feel risky. But with the right approach, you can modernize without bringing […]
This post was originally published in 2023 and was updated in 2025. PostgreSQL is a natural fit for modern cloud-native environments, but running it on Kubernetes can be more complicated than it looks. From provisioning to backups, there’s a lot to get right before you can start building on top of it. That’s where the […]
This post was originally published in 2023, and we’ve updated it in 2025 for clarity and relevance, reflecting current practices while honoring its original perspective. Running PostgreSQL on Kubernetes promises flexibility, but storage decisions can quickly make or break your deployment. From balancing cost with performance to ensuring high availability, every choice adds complexity. That’s […]
This blog was originally published in August 2022 and was updated in April 2025. In this blog, we’ll examine the increasingly popular practice of running MongoDB on Kubernetes. We will explore various solutions and approaches to this setup, from direct deployments as a stateful application to utilizing specialized operators and considering cloud-based solutions, guiding you […]
At Percona, we’re committed to providing you with the best database monitoring and management tools. With the release of Percona Monitoring and Management 3 (PMM 3), we’re now entering a critical phase in the lifecycle of PMM 2. We understand that PMM 2 remains a vital tool for many of our users, and we want […]
Recently I listened to Lenny Rachitsky’s podcast, where he invited Shreyas Doshi for the second time. The session was titled “4 questions Shreyas Doshi wishes he’d asked himself sooner”. One of the questions Shreyas brought up was, “Do I actually have a good taste?”. This is an interesting question to ask for an experienced product […]
I wrote a blog post in the past about a generic approach on how to expose databases in Kubernetes with Ingress controllers. Today, we will dive deeper into PostgreSQL with ingress and also review two different ways that can be taken to expose the TCP service. The goal is to expose multiple PostgreSQL clusters through […]
There are various ways to backup and restore Percona Server for MongoDB clusters when you run them on Kubernetes. Percona Operator for MongoDB utilizes Percona Backup for MongoDB (PBM) to take physical and logical backups, continuously upload oplogs to object storage, and maintain the backup lifecycle. Cloud providers and various storage solutions provide the capability […]
Managing database users within complex CICD pipelines and GitOps workflows has long been a challenge for MongoDB deployments. With Percona Operator for MongoDB 1.17, we introduce a new feature, currently in technical preview, that streamlines this process. Now, you can create the database users you need directly within the operator, eliminating the need to wait […]
In the first part of this series, we built a basic AI-powered database agent. Now, it’s time to make a minimal viable product out of it. We’ll refine our scripts, add support for MySQL, incorporate OpenAI, and wrap everything in a user-friendly interface with Docker for easy deployment. Get ready to transform your data interactions […]
Generative AI is top of mind for many engineers. The questions of how it can be applied to solve business problems and boost productivity are still up in the air. Recently I wrote a blog post about the impact of AI on platform engineers, where I talked about various AI Agents and how they can […]
PostgreSQL major versions are released every year, with each release delivering better performance and new features. With such rapid innovation, it is inevitable that there will be a need to upgrade from one version to another. Upgrade procedures are usually very complex and require thorough planning. With the 2.4.0 release of Percona Operator for PostgreSQL, […]
This is the second part of the series of blog posts unmasking the complexity of MongoDB cluster exposure in Kubernetes with Percona Operator for MongoDB. In the first part, we focused heavily on split horizons and a single replica set. In this part, we will expose a sharded cluster and a single replica set with […]
Running and managing MongoDB clusters in Kubernetes is made easy with the Percona Operator for MongoDB. Some aspects are just easy to grasp as they are well defined in the operator custom resources and documentation, but some are often considered to be a hidden craft. Network exposure in cases of sharded clusters is quite straightforward, […]
In November 2023, Bill Gates wrote an article about how AI would change the way we interact with computers and personal devices through so-called Agents: “Agents are not only going to change how everyone interacts with computers. They’re also going to upend the software industry, bringing about the biggest revolution in computing since we went from […]
Coroot, an open source observability tool powered by eBPF, went generally available with version 1.0 last week. As this tool is cloud-native, we were curious to know how it can help troubleshoot databases on Kubernetes. In this blog post, we will see how to quickly debug PostgreSQL with Coroot and Percona Operator for PostgreSQL. Prepare […]
Cloud-native databases are becoming the norm, and containerized databases are a common trend (see the report from Dynatrace and Figure 1). Kubernetes—the de facto standard for platform engineers—and operators simplify database deployment and management. But what are the performance implications of running databases in Kubernetes? To answer this question, we compared the performance of Percona Server […]
