details

DevOps is an approach to software development that is based on lean or agile practices. It combines tools and methods from software development (Dev) and IT operations (Ops). DevOps improves responsiveness to market needs and shortens the software development life cycle (SDLC) and time-to-market.

CI/CD pipeline: why it makes sense for your startup

Today, the world of software and app development evolves rapidly. Both startups and larger companies keep bringing more and faster enhancements and functionality to the market to stay ahead of the competition. In order to maintain the pace of development and increase efficiency, development teams need to constantly optimize their workflow. One of the methods to both develop and sustain business reliability is the implementation of a CI/CD pipeline. It is now one of the fundamental practices for DevOps implementation in startups and one of the best practices that allow DevOps teams to deliver code more frequently and reliably.

Business benefits of CI/CD

Rare releases, tons of manual work, critical bugs detected too late, ineffective and late feedback—these problems plague the software development process many companies keep in place. They can be tackled by turning to continuous integration coupled with Continuous Delivery/Continuous Deployment, which will also generate more value for your customers/clients. Read on to understand what business benefits of CI/CD you may expect in your company. In the traditional approach to software development, major releases were spread out, occurring quite rarely—every six months, for example.

Continuous monitoring and observability in CI/CD

Deploying a CI/CD pipeline is only a half success. To complete the deployment, you need to establish continuous monitoring and observability which will allow you to collect metrics and actionable insights. In this blogpost you will learn about the principles of monitoring and observability, how they are related and how automation can streamline the entire deployment process. DevOps culture is a good starting point here, as understanding the DevOps advantages and its principles will allow you to contextualize continuous monitoring and observability.

How to set up and optimize a CI/CD pipeline

Nowadays you will hear that if you want your SDLC (Software Development Lifecycle) to be efficient, you need to have a proper, well-established CI/CD setup. In most cases, it’s true. In this blog post I am going to focus on how to go about creating such a setup when creating a new CI/CD pipeline and optimizing an existing one. I will also look at best practices to follow and outline errors to avoid. Finally, I will analyze the possible reasons why your CI/CD setup may not work as expected and propose solutions to turn things around.

Sharing configuration between your CI, build and development environments

This post is a follow-up to our presentation at the OpenStack Summit in Berlin, where we discussed maintaining a unified CI and building pipelines using the open source CI system, Zuul. You’ll find a recording of the talk here and a related OpenStack Superuser writeup here. I thought it would be useful for some of you to expand the concept of unifying environments and to include also the development one. I will also explain why this may help you ensure your project is progressing smoothly. DevOps practitioners are always on the lookout for ways to optimize and bulletproof their development workflows.

Do you even Zuul? CI system reloaded

When we first started, we were given two things to do: resolve issues with builds getting gradually slower and set up a completely new system that Tungsten Fabric could use. Over the years, Tungsten Fabric has received commits from more than 500 contributors and the code is scattered across over 50 repositories. The entire project consists of over 2 million lines of code, written mostly in C++ and Python. In the beginning of the project few major tasks emerged: prepare the CI for the increased involvement of the community;

CI/CD of CI/CD — how to avoid technical debt while delivering cutting edge software

When a company’s core business is delivering software, the tools it chooses to use are crucial to maintaining efficiency. Thus there is no reason to deliver CI/CD software in a model other than CI/CD. After we deliver shiny new CI/CD software to our clients, the work is hardly done. The software ages and the technical debt runs up. According to Deloitte, the typical application comes with $3.61 worth of technical debt per line of code. That debt accounts for every fast-but-imperfect patch or app architecture that ages and also makes innovations hard to apply.

Legacy code: a time bomb for your business?

Due to a technical failure, Delta Airlines had to cancel 2,300 flights. The problem was neither in the planes nor the company’s infrastructure. The reason for the chaos, clients' disappointment and the subsequent cut in profit guidance for the third quarter was simply aging software. This article will explain: What legacy code is? Why it is presenting companies with such a challenge? How we solve such problems? The problem with aging software and legacy apps afflicts every industry, from banking to insurance to telecommunications.
