The key to acing a CI/CD interview is preparation. The first step in preparation is to learn as much as you can about the possible company, including its background, offerings, and hiring practices. In order to help you master your next interview and land your dream job, this blog post includes CICD interview questions, all neatly organized into themes.. Refreshing your technical knowledge is the next item on the list because it will help you stand apart.

Action time: Automate your pull request with GitHub Actions.

The traditional embedded Linux development model ties applications to the OS. Such a constraint means apps have to target a specific release, which lowers development velocity. Furthermore, broken upgrades in one part of the device may affect refreshes in the rest of the OS. On the other hand, embedded developers are increasingly looking at open-source software to enable rapid app-centric software deployment and global collaboration.

Speedscale creates load tests from recorded traffic so generating load is pretty core to what we do. As a brief overview, we record traffic from your service in one environment and replay it in another, optionally increasing load several fold. During a replay the Speedscale load generator makes requests against the system under test (SUT), with the responses from external dependencies like APIs or a payment processor optionally mocked out for consistency. Your service is the SUT here.

For decades, IT operations teams have relied on monitoring for insight into the availability and performance of their systems. But the shift to more advanced IT technologies and practices is driving the need for more than monitoring – and so observability evolved. With infrastructures and applications that span multiple dynamic, distributed and modular IT environments, organizations need a deeper, more precise understanding of everything that happens within these systems.

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. With the launch of Level 1 (Fundamentals), we have seen an unprecedented interest from people that want to learn about GitOps resulting in over 10,000 students and 3,000 certified engineers!

A quick search of the internet will reveal many services available for freely hosting single page applications or static sites. Firebase is one of these services. 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.

Thanks to the power of open source tooling and cloud services, shipping an application to production has never been that easy, In this blog post, we are going to go from bootstrapping a Next.js application to deploying it on Vercel. We will use Github Action to handle the Continuous Integration and Sentry to monitor the application once it is deployed to be warned of any problems as soon as it arrives.

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.
