Best CI/CD security tools

Continuous Integration and Continuous Delivery (CI/CD Tools) are combined DevOps best practices for automating different application development stages. At its core, a CI/CD pipeline enforces automation by removing team-level silos and incorporating tools that enable efficiency.

During pre-DevOps days, software development and deployment involved manual identification of bugs and then rolling out the fixes. Unfortunately, this model made different teams treat their tasks as discreet projects without relating to other components, ignoring effective collaboration.

What is continuous integration?

The concept of Continuous Integration first hit the headlines in 1994, leading to the introduction of  CruiseControl, the first CI tool. Years later, the concept of Continuous Delivery emerged to improve on the demerits of Continuous Integration. Since then, CI/CD practices have further enhanced with broader adoption within the industry to the extent that today, most of the DevOps operations are driven by CI/CD entails automation and team collaboration in phases, including development, deployment, integration, testing, and monitoring.

Best CI/CD tools

When choosing a CI/CD tool, it is essential to consider ease of setup, interoperability, integration with IDE, cloud services, and price per pull/push requests. We have researched and tested many of these tools and created a list to find all the relevant information you need when choosing a CI/CD tool. So, We hope it will be helpful for your final decision.

Let us go through the best CI/CD tools List while exploring their features.

Travis CI

Travis CI is another popular open-source CI/CD tool that integrates with GitHub and Bitbucket and is usually more user-friendly than its peers. Instead of using the build-agent approach, Travis CI uses a clean room approach for builds. This essentially enables every build to run in a new and consistent environment. While the Free version is entirely cloud-based, the Enterprise version can also be hosted on-premise or private cloud.

The following representation shows a typical CI Pipeline through Travis CI while integrating the workflow into a Docker container. Where Ansible is considered to help automate provisioning, setup, and configuration of the underlying infrastructure.
