If you need to reduce the amount of metrics data stored in your time series database (TSDB) or improve query performance, there are generally two common methods to do so.

For metrics stored within Prometheus, the Prometheus Querying Language (PromQL) is the main way to query and retrieve the results you are looking for. Chronosphere supports querying metrics data using PromQL and Graphite functions, but as PromQL is the most popular option we see customers use. PromQL has some differences to other query languages you might have used. Here is an overview guide to get you started.

As many large-scale events start to feel they’re close to “getting back to normal,” this year’s KubeCon EU was the second online, and while it lacked any large announcements, there was plenty of consolidation and maturing of concepts.

Software development practices change fast. Development teams use an endless stream of new tools, frameworks, and practices, and it’s your job as a test engineer to make sure that no matter what your development teams use or create, everything runs and works reliably.

GitOps takes familiar tools such as Git and Continuous Delivery pipelines to automate infrastructure. The GitOps approach is vendor-neutral, provides a clear history of changes, and allows you to reproduce or roll back deployments. Yet, we can't ignore the problems with this approach: Proliferation of repositories, no help for secrets management, or simultaneous file writes. Let's explore.

How can playing roleplaying games help development teams work together better? Chris speaks with Karthik Nagarajan to find out.

When comparing products, you want to decide on their usefulness. Yet, we often forget to evaluate the project's documentation. A project might offer an excellent set of features but might lack easy-to-use documentation. This can have a detrimental effect on the developer experience and your team's efficiency. So, how do you evaluate the developer experience of documentation?

Many of you have probably read countless technical articles about scaling application infrastructure and capacity with Kubernetes. This is not one of those posts. Rather, it looks at how and when to implement Kubernetes when your team or the demands on your team grow rapidly.

I won’t repeat any famous phrases about how pictures equalling a quantity of words, I think we all understand the potential power of a good visual. Well considered images in documentation can help illustrate a concept, clarify a complex idea, or show a reader what they can expect from undertaking certain steps.

I ran a live stream a while back where I looked at new features in

If you want to build your applications and business on existing APIs and not reinvent all functionality yourself, how do you decide between the plethora of options available? This article helps you make that decision based on the developer experience (DX) you should expect from an API.

An Internal Developer Platform (IDP) is an essential step for rapidly scaling companies to keep their developers working productively and happily. In this roundtable discussion we speak with Jason Warner, the current CTO of GitHub and previous VP of Engineering for Heroku about how IDPs help teams of that scale build efficiently.

German broadcaster Sport1 realized they were spending too much time grappling with an outdated deployment process, they decided it was time to build their own flexible Internal Developer Platform. Find out how it changed their development process in our roundtable with Paolo Garri, the director of technology.

A major bug urgently needs fixing in Production, but QA is impossible because Staging is ahead of Prod. This blog post will detail how to clone your Production environment to allow immediate testing before hot-fixing Production.

At the end of September 2020, participants from Humanitec and Polar Squad met for a small hackathon to see how straightforward it was to create a resource driver for the Humanitec platform so that others can connect their custom infrastructure.

An internal developer platform (IDP) is an essential step for rapidly scaling companies to keep their developers working productively and happily. In this roundtable discussion we speak with Jan Löffler who helped build Zalando’s IDP about the problems they were trying to solve and the steps they took.

In this article I look mostly at improving the developer experience within a company, and touch upon other aspects where relevant, we have future articles planned to help you improve the DX of the projects you maintain. The goal of this article is to help those in charge of development teams understand what their developers struggle with and complain about and help them do something about it.

This Weekly Squeak, I speak with Tanmai Gopal about Hasura, an open source and hosted platform that brings instant GraphQL APIs to your data.

Your Kubernetes configuration represents environments that are a fundamental part of your application, unyet we generally treat them as less important from our application code. In this post we look at best practices for managing changes to configuration, and how to treat it the way it deserves.

I wanted to create a cross-platform app to aggregate all my todos across various services. I turned to Flutter; was it a good idea? Read on to find out.

If you're looking to build a chatbot to support a customer base, Einstein from Salesforce might be an option to consider. Chris Ward dives in to see what's possible.

In this article by Nils Balkow Tychsen, Lead Q&A Engineer at Humanitec, you will learn some use cases for sandboxed environments such as parallel feature development, parallel testing of feature flags, and parallel testing of microservice versions in different combinations.

A good developer experience is crucial to keep developer teams productive, happy, and focussed on work important to your business aims. In this first roundtable, we get the opinions and experiences from two experts in the field: Nigel Simpson, Director, Enterprise Tech Strategy at a Fortune 100 company, and Erik Muttersbach, CTO at forto (formerly FreightHub), a Berlin logistics startup.

In this article, we look at ephemeral testing environments, small, discrete, and short-lived testing environments that reflect only the changes you are interested in testing.

Take a look at using Heroku to host the microservices behind a small bot project the author maintains.

Despite sounding similar, continuous integration, delivery, and deployment are subtly different from each other. While they have overlap, they are applicable and useful at different stages of the development process. In this post, we look at what the different terms mean, what benefits they bring to you and your team, and what you need to get started implementing the practice.

Continuous delivery helps software development teams get their code changes from development to testing, and into the hands of users more quickly. In this post, Chris Ward looks at the benefits and best practices for implementing this practice into your teams.

Environment variables are a common way for developers to move application and infrastructure configuration into an external source outside of application code. This post shows you the variety of ways Kuberentes helps you create and manage environment variables within kubernetes.

Software developers submit a pull request (often abbreviated to PR) in their git system like GitHub, GitLab or BitBucket to signal to their teammates or manager that a branch or fork they have been working on is ready for review.

As open-source projects grow in use and popularity, many of their maintainers face a challenge to understand how and how many people use their tools.
