One of the game changers in modern software development is Continuous Integration and Continuous Development (CI/CD). Both large, established organizations and small, growing companies use CI/CD to deliver software faster and to detect bugs in the software lifecycle. In this tutorial, I’ll create a full pipeline to practice CI/CD using Jenkins, including how to set up Jenkins on Docker. I’ll give an in-depth view of a Jenkins pipeline example using Jenkinsfile.

Data observability turns the focus back on the data to improve data quality, tune data infrastructure and identify problems in data engineering pipelines and processes. “Data analysts and business users are the primary consumers of this data,” said Steven Zhang, director of engineering at Hippo Insurance.

Organizing a software release is a cross-team effort and a large undertaking. Leveraging the power of Mattermost Playbooks can help your team stay on deadline and keep confusion at bay. In this post, we’ll learn how to quickly integrate Mattermost into your GitLab release pipeline to help streamline your release processes. At the end of the blog post, there’s a link to a release management demo that you can try out in the browser to see these ideas in action.

A mission-critical application is a software program or suite of related programs that must function continuously in order for a business or segment of a business to be successful.
