Some time ago Federico Toledo published Performance Testing with OpenSource Tools- Busting The Myths. Otherwise we wouldn’t see so many commercial tools built on the top of opensource including BlazeMeter (it is ironic that the article is posted on the BlazeMeter site), Flood, and OctoPerf.
Andreas Grabner, DevOps Activist at Dynatrace, took to the virtual stage at the recent Dynatrace Perform conference to describe how the opensource Keptn project automates the configuration of observability tools, dashboards, and alerting based on service-level objectives (SLOs). Too many SLOs create complexity for DevOps.

It is not equal to the average of per sequence values.
As you may agree, it is important to test your code. Often I saw that this is not tested thoroughly or not at all. With Testcontainers , writing integration tests has become a commodity. The library is available on Maven Central and Github for everyone.
My post Good Times for Load Testing was published in 2014. It is difficult to believe that 5 years passed… Are times still good for load testing? If we speak about commercial load testing tools, we see rather a shrinking market and not too much innovation recently. OpenSource. Well, yes and no.
OpenTelemetry Astronomy Shop is a demo application created by the OpenTelemetry community to showcase the features and capabilities of the popular open-source OpenTelemetry observability standard. You can also use it to test different OpenTelemetry features and evaluate how they appear on backends. metrics from span data.
We are a company of opensource proponents. We’re also dedicated and active participants in the global opensource community. Both opensource and proprietary options have advantages. With opensource database software , anyone in the general public can access the source code, read it, and modify it.
For gaining maximum benefits out of automation testing , testers require hands-on experience in a minimum of one automation programming language. There are numerous programming languages available today, with new ones continuously emerging. Which Automation Programming Language Is the Best for Testing?
DevOps platform engineers are responsible for cloud platform availability and performance, as well as the efficiency of virtual bandwidth, routers, switches, virtual private networks, firewalls, and network management. Version control system and source code management with end-to-end DevOps platform and cloud-hosted Git services.
Even though opensource software is firmly in the mainstream, used widely by businesses, governments, and everyone who owns a cell phone or computer, the question repeatedly arises: “Is opensource software safe?” Is opensource software as stable as other software? Our bar is higher than that.
The use of opensource databases has increased steadily in recent years. Past trepidation — about perceived vulnerabilities and performance issues — has faded as decision makers realize what an “opensource database” really is and what it offers. What is an opensource database?
With limited freedom of choice and the burden of navigating complex infrastructures, companies often find themselves bound to single cloud providers, restricting their ability to take advantage of the best available tools and services. By default, Everest uses the kubeconfig file available under ~/.kube/config. kube/config.
Many organizations are turning to opensource solutions to streamline their operations and reduce costs. Opensource migration can be a game-changer, offering flexibility, scalability, and cost-effectiveness. Below, we’ll explore the common pitfalls of opensource migration and provide insights on how to avoid them.
Automation testing tools are designed to execute automated test scripts to validate software requirements, both functional and non-functional. Automation testing technologies facilitate the creation, execution, and maintenance of tests effortlessly while providing a consolidated view of test result analytics.
The unstoppable rise of opensource databases. One database in particular is causing a huge dent in Oracle’s market share – opensource PostgreSQL. See how opensource PostgreSQL Community version costs compare to Oracle Standard Edition and Oracle Enterprise Edition. What’s causing this massive shift?
Migrating a proprietary database to opensource is a major decision that can significantly affect your organization. Advantages of migrating to opensource For many reasons mentioned earlier, organizations are increasingly shifting towards opensource databases for their data management needs.
Open-source software drives a vibrant Kubernetes ecosystem. That trend will likely continue as Kubernetes security awareness further rises and a new class of security solutions becomes available. Opensource software drives a vibrant Kubernetes ecosystem. Java, Go, and Node.js Kubernetes moved to the cloud in 2022.
MongoDB has the most advanced continuous performance testing I know about. MongoDB shared a lot of information on how we do performance testing and even opensourced some parts of it. Continuous performance testing is built on the top of Evergreen. If I missed something interesting, please let me know.]
Application developers commonly leverage open-source software when building containerized applications. In fact, the market research firm Forrester says that the average container image is comprised of 70% open-source software.[1] 1] And unfortunately, open-source software is often fraught with security vulnerabilities.
The ability to isolate certain software capabilities makes it easier to test, preview, release, and roll back small functional increments. This approach gives teams a high degree of flexibility and control over testing, beta releases, access privileges, and feature lifecycles. Were conversion goals impacted?
In the agile environment, developers need to run relevant cross-browser tests to push any front-end changes quickly. While small projects use manual testing, larger projects need automation because of the increasing number of web browsers. Selenium is one of the most popular open-source web automation testing tools available today.
To make data count and to ensure cloud computing is unabated, companies and organizations must have highly available databases. This guide provides an overview of what high availability means, the components involved, how to measure high availability, and how to achieve it. How does high availability work?
The time and effort saved with testing and deployment are a game-changer for DevOps. This opens the door to auto-scalable applications, which effortlessly matches the demands of rapidly growing and varying user traffic. In production, containers are easy to replicate. Here the overlap with Kubernetes begins. What is Kubernetes?
In these modern environments, every hardware, software, and cloud infrastructure component and every container, open-source tool, and microservice generates records of every activity. Open-source solutions, such as OpenTelemetry , provide a de facto standard for collecting telemetry data in cloud settings.

Is my database cluster still highly available? All of our high availability options are offered in DigitalOcean, including 2 Replicas + 1 Arbiter, 3 Replicas and custom replica set setups. DigitalOcean does not have the concept of availability zones (AZ), so we distribute the nodes across different regions. High performance.
GitHub workflows can be quite complex, executing dozens of individual build, test, and deployment steps. Multiple GitHub Actions are available within the GitHub Marketplace : The use of GitHub Workflows is straight forward as their configurations are stored in your GitHub repository.
Frequently, practitioners want to experiment with variants of these flows, testing new data, new parameterizations, or new algorithms, while keeping the overall structure of the flow or flowsintact. The standard dictionary subscript notation is also available. You can access Configs of any past runs easily through the Client API.
It looks like we succeeded, and I’m happy to announce that Percona Distribution for PostgreSQL 16 is now available! We plan to make Percona images for PostgreSQL available on Docker Hub shortly. We’re hoping to share some good news in this regard and provide an MVP for all of you to try and test by the end of this year.
When it comes to access to their applications, users demand instant, reliable, and secure interactions — and that means databases must be highly available. With database high availability (HA), services are largely uninterrupted, and end users are largely satisfied. The obvious answer is this: To achieve high availability.
