Sergey ProninRecently 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 […]
Volume Expansion, a feature that became generally available since Kubernetes version 1.24, allows users to increase the capacity of their Persistent Volumes and underlying storage within Kubernetes. There is no need to use clouds’ UI or APIs to do that anymore. In our Operators, we use Stateful Sets – a Kubernetes resource that was designed […]
I really like AWS and the way they build their products, I really do. But for some reason, AWS Elastic Kubernetes Service (EKS) provides one of the worst user experiences. There are a couple of huge pain points that I want to cover in this quick blog post. Cluster deployment Tooling – AWS CLI It […]
Percona Operator for PostgreSQL is now Red Hat OpenShift certified. You can now use Percona Operator for PostgreSQL to deploy and manage highly available PostgreSQL clusters on OpenShift. Certification guarantees that our Operator meets standards for interoperability, security, and life cycle management when deployed on Red Hat OpenShift. It is fully supported by Red Hat’s […]
According to CNCF surveys, security is always among the top concerns for Kubernetes practitioners and platform engineers. Percona Everest — an open source cloud-native database platform – is now in Alpha stage, but it is important to set it up properly from day 0. In this blog post, we will explain how to run Everest UI […]
2023 was the year of Artificial Intelligence (AI). A lot of companies are thinking about how they can improve user experience with AI, and the most usual first step is to use company data (internal docs, ticketing systems, etc.) to answer customer questions faster and (or) automatically. In this blog post, we will explain the […]
This blog was originally published in August 2022 and was updated in January 2024. In this blog, we’ll examine the increasingly popular practice of deploying MongoDB on Kubernetes and explore various approaches to this setup. From direct deployments as a stateful application to utilizing specialized operators and considering cloud-based solutions, we’ll guide you through the […]
The evolution of cloud-native technology has been nothing short of revolutionary. As we step into 2024, the cornerstone of cloud-native technology, Kubernetes, will turn ten years old. It continues to solidify its position and is anticipated to reach USD 5575.67 million by 2028, with a forecasted Compound Annual Growth Rate (CAGR) of 18.51% in the […]
Deploying PostgreSQL on Kubernetes is not new and can be easily streamlined through various Operators, including Percona’s. There are a wealth of options on how you can approach storage configuration in Percona Operator for PostgreSQL, and in this blog post, we review various storage strategies — from basics to more sophisticated use cases. The basics […]
