Best 19 CI/CD Tools to Watch out in 2020

banner background

With the rising popularity of DevOps, practices of continuous delivery and integration are becoming mainstream. Developers and business owners want to deliver products to the market without sacrificing its quality — this can be achieved with frequent, continuous releases. After reading this guide, you’ll know where to start implementing CI into your development and which continuous integration tools to pick. So, let’s start.

What is continuous integration?

Before we start talking about practices, let’s make sure we understand the definition of the content. Continuous integration is an approach where software development, testing, and operation teams can update and view code on the shared server. This code can be open to the final user or protected from visibility. If you integrate new code automatically, other team members can take a look at it, find errors, and delete them early on.

Advantages of CI

By regularly refreshing your code, you prevent many errors, but also, get additional advantages:

  • Updating small chunks of code. By integrating one code piece at a time, you make mistake recognition and testing much easier. If, after integration, you detected issues in the code file, you’ll know exactly what chunks of code contributed to each of them. Issues don’t pile up and are managed quickly.
  • Faster Mean Time To Resolution: this metric, also known as MTTR, describes how much time is needed to repair a broken piece of functionality. You can isolate a fault and remove it before it affects the entire performance.
  • A more intuitive backlog: small defects are grouped by particular code chunks — developers and testers can navigate between iterations and see issues as they appear.

What is continuous delivery?

It’s a delivery approach where the software is quickly tested and deployed after a new iteration was created. Developers aim at releasing more uploads as opposed to publishing one big file with multiple improvements. The CD approach implies uninterrupted cooperation with testers and operations specialists — all these team members are briefed in on the project changes.

The benefits of continuous delivery

  • You can quickly release an innovative product: today businesses invest in the same tech stacks and innovations – AI, VR, AR, blockchain. The timing of a new release is crucial for the solution’s success.
  • Code stability: by delivering small changes to the file, you decrease the risks of accumulating technical issues and errors.
  • Reduced duration: the team can update the product, get customer feedback, and get up to speed with fixes instead of piling up errors and having to solve technical problems after the release.

The benefits of CI tools

To implement continuous integration and delivery, software development teams use specialized tools — web or desktop platforms that automate the deployment processes, run automated tests, provide information on software status, connect involved team members, and facilitate product management. Let’s take a look at the main advantages of using dedicated software for CI/CD.

  • Automation: you can automate repetitive work in development, testing, deployment, maintenance by using automated DevOps solutions;
  • Collaboration: CI/CD requires the team to connect experts from various departments, and specialized platforms create an intuitive environment for this long-term cooperation;
  • Transparent management: CI/CD tools allow team members and managers to keep track of CI/CD processes, create tasks, work with the backlog, receive regular reports, and code quality evaluation;
  • Running multiple builds on various OS: CI/CD platforms provide tools for cross-platform software deployment and increase its visibility.

Best continuous delivery tools and integration platforms in 2020

The practices of continuous delivery and integration are growing increasingly popular with the rise of DevOps — the methodology that implies continuous cooperation between development and operation departments.

Testers and developers cooperate at the early stages of the project, detecting and removing errors as they appear, one by one. That is why we’ve seen a rise in various CI/CD projects that serve multiple goals. Some focus on automation, others have a management scope — and making sense of this variety of solutions is often overwhelming. We made a continuous deployment tools list, so you’ll be able to distinguish them better and choose the one that fits your needs.

How to choose a CD/CI tool that fits your business?

Best continuous integration and deployment tools differ by their pricing, functionality, and interface. Each solution offers a unique library of add-ons and integrations, so the choice also depends on what kind of tools you use for your workflow. Don’t rush narrowing the choice options down to a single one — start by picking 2-3 platforms and testing them out. To make this choice, look at the following requirements.

how to choose ci/cd tool

Hosting settings

Some companies use cloud storage, whereas others use local networks. If your company uses cloud computing, look for services that use cloud servers — Azure, AWS. Many servers offer the possibility to replicate the Cloud data to the local network — it’s obviously a bonus.

Also, analyze the software data protection algorithms. Check if the solution hides the source code, provides different user roles, and access customization. Some software deploy tools also allow hiding the deployment environment behind your private firewall.

Budget

The thing to keep in mind is that open-source software usually has a narrow specialization — it might focus on deploying files from code repositories or providing smooth team collaboration.

Complex platforms, like Azure DevOps, offer as much functionality as 5-6 open-source continuous integration solutions, but it’s significantly more expensive. Typically, small businesses and startups use cheaper services, whereas big companies opt for enterprise-level applications.

Functionality

Ideally, you want a flexible solution that allows you to choose your go-to feature plan. Look for platforms that have a pay-per-use pricing model. You won’t overpay for excessive functionality that complicates the user experience, but you’ll have an opportunity to scale once your team grows.

Also, pay attention to integration. In our experience, the solution should support code repositories, GitHub, Cloud storage, Visual Studio, Azure. From a long-term perspective, having access to these integrations creates you space for growth and helps to scale the product.

Community

Ensure that the contributing community is active and enthusiastic – it will supply you with multiple add-ons and plugins. Make sure you have access to community forums, message boards, support teams, Wiki files, and guides.

If you purchase a paid solution, examine customer reviews to see the reliability of the support team, explore the functionality of the platform through trial versions, and contact the official members before the purchase.

Final thoughts

Finally, CICD tools should be considered a long-term business investment. When you pick the software for development and integration, consider not only the needs at hand but also the long-term perspective. Aspiring for smaller, cheaper solutions may be the right fit for current projects, but as your team scales, you’ll need more features and integrations.

Therefore, before starting a CD/CI integration, you need to outline the goals that a tool will help your team to achieve. These can be regular quality checks, shortened time to release, improved product quality (better user feedback, less tech debt, fewer bugs), optimized team cooperation (less time spent for legacy work, less time spent per feature, effective feedback, short loops). Feel free to reach out to us and we will handle all the necessary development for you.
