Continuous integration (CI) demands continous testing: shifting left helps prevent faulty code from spreading, which is one of the core aims of CI. Datadog’s new Azure DevOps extension enables you to seamlessly incorporate integration and end-to-end tests into existing CI/CD workflows on Azure Pipelines, a dedicated CI/CD service that automatically runs builds, performs tests, and deploys your services and applications via cloud-hosted pipelines.

Reliability is a critical concern for software delivery teams. Every second of lackluster performance or service interruption comes with high costs. The consequences can extend beyond just monetary expenses and have a huge impact on a company’s reputation. In a survey conducted in 2022, participants reported that over 60% of digital infrastructure failures resulted in losses of $100,000 or more.

At Vela Games, we use CircleCI for building Project-V, our new multiplayer online co-op (MOCO) game that fuses the teamplay and skill of a multiplayer online battle arena (MOBA) game with the adventure of a massively multiplayer online (MMO) dungeon run.

How do you treat software development failure? Do you take time to measure and learn from software failure? Or do you try to fix it quickly only after your customers complain about it? Failure can be an opportunity to learn and get better. So how can you measure and learn from software failure, and turn failure into at least a partially positive experience? Failure happens all the time, but if you're not measuring it, how do you know what you’re missing?

Firebase is a development platform developed by Google that provides file storage, hosting, database, authentication, and analytics. It is free, provides an SSL certificate by default, and offers impressive speed across multiple regions. I have chosen Firebase for hosting our demo application in this tutorial.

It's not like it used to be back in the day! Before CI/CD, we were building on-premises, service-oriented products following system style architecture and we were able to map out the build system and end-to-end process in a PowerPoint or Visio document. Although time-consuming and inefficient, it was relatively straightforward and the build pipeline was unlikely to change drastically. But that's no longer the case.

At the start of this year, Codefresh announced the first ever GitOps certification for Argo CD. The certification consists of 3 different levels covering GitOps end-to-end from beginning to end.

Microservice architecture is an application system design pattern in which an entire business application is composed of individual functional scoped services, which can scale on demand. Each team focuses on an individual service and builds it according to their skillset or language of choice. In addition to flexibility, this pattern provides: These features have made microservices architecture a popular choice for enterprises.

By implementing CI/CD in your software development process, you can build high-quality software faster and easier than ever before. However, despite its many benefits, many challenges still arise when scaling up CI/CD pipeline process, such as increasing throughput or reducing wait times, just to name a couple.

Scan your packages for vulnerabilities and never miss new vulnerabilities as they get discovered. Create actionable workflows by quarantining packages over defined vulnerability levels.

In this article, I’ll show you how to reduce the execution time of XCUITest (UI tests on iOS simulators) by splitting and running them in parallel. Automated tests and CI/CD platforms like CircleCI are necessary for iOS application development. It is important not only to introduce them once but to improve them continuously. When application code grows and automated tests increase, the execution time of build and test in CI/CD gets longer.

In this era where applications are taking over the world, delivering the service to your customer with scalability and security is of the utmost importance.

As enterprises adopt cloud-based technologies, their IT infrastructure becomes more complex. The need to constantly scale up the CI/CD pipeline presents new challenges for IT teams. This blog post will share best practices and learnings from our work with enterprise customers who have successfully scaled up their CI/CD pipelines and discuss how to solve these challenges with Cloudify in production environments.

Even before the cloud, no one liked deployment downtime. With applications hosted in traditional data centers that restricted access for local users, many organizations scheduled deployments when users were less likely to be using the applications, like the middle of the night. With widespread adoption of cloud-based, 24x7 environments available from all time zones, every hour of the day, easy-to-find deployment windows are gone.

This post, authored by CircleCI Senior Technical Content Marketing Manager Jacob Schmitt, was originally published on The New Stack. One of the privileges of working in the continuous integration space is the unique perspective it offers into how software teams organize their work to deliver value quickly without sacrificing quality, security, or developer happiness. At CircleCI, we support more than 2 million developers running 90 million build, test, and deploy jobs each month.

A Docker image is a combination of instructions and for creating a docker container a instruction is used to execute code in a Docker container. Docker images work as a set of instructions to build and run a Docker container, as a template. Docker images also perform as the initial point when using Docker. A Docker image contains read-only files. when a docker image is created it can not be changed and modified, insert template that has instructions for deploying containers.

One of the leading frameworks in the JavaScript community, Vue.js is a progressive framework for building reusable components for the web user interface.
