Thinking about forming a new DevOps team? Our DevOps roles and responsibilities article offers an overview of everyone you’ll need in the new department.

Source Code Management Tools

Source code management is a vital aspect of the DevOps culture that includes tasks such as:

• Version control. Issue tracking.
• Code review.
• Code packaging.
• Automated tests for code quality.
• Below is a list of the best DevOps tools for managing, organizing, and reviewing source code.
• Git
• Git is an open-source platform for version control that enables DevOps teams to track changes in source code. By default, Git is a distributed SCM command line tool, but developers can also download the Git GUI client with a user-friendly interface.

Integrating Git with a DevOps workflow requires the team to host source code in repositories where developers push their work. The three most popular Git repo hosting services are:

• GitHub (the most popular option with 56+ million users).
• GitLab (around 30 million registered users).
• Bitbucket (over 10 million users).

All three options offer both public and private repositories, plus provide users with additional DevOps features, such as:

• Git increases the speed and data integrity for non-linear, distributed workflows no matter what repo you choose.Main features of Git:

A free, easy-to-learn tool for source code management that effectively handles projects of all scales.

Works on Windows, macOS, Linux, Solaris, and AIX.

Enables users to save different source code versions and revert to a previous commit.

• Teams get to create separate branches and experiment before merging a new feature.
• Direct integrations with IDEs like VS Code, Eclipse, and IntelliJ.
• Multiple DevOps-friendly features (staging environments, multiple workflows, commits, check-ins, local branching, etc. The three most popular No worries–here are a few articles to get you started:
• Mercurial
• is an open-source SCM tool that efficiently handles projects of any size. While not as popular as Git, Mercurial is the SCM tool behind several notable projects, including:
• Facebook.

• Mozilla.
• Mercurial
• OpenSolaris.
• Open JDK.
• Like Git, Mercurial is a distributed tool that uses a decentralized model when creating local or private copies of project history.
• Main features of Mercurial:
• A free Python-based SCM platform with an easy and intuitive interface.
• Support for all major platforms.

Every cloned repository contains the whole project history, so user actions occur locally and quickly.

Actions like committing, branching, and merging occur without the need to establish network access.

• Supports many workflows and practices (scalable workflows, merging and conflict reconciliation, multiple working trees, cloning of a repository to a backup commit, etc. ).
• Easy to enhance functionality with extensions (either pre-built Python-based add-ons, custom ones, or from a third party).
• An excellent Quick Start Guide and knowledge base.
• Considering adopting DevOps? Our guide to simple DevOps transition offers valuable insights and tips that help you through this challenging IT shift.
• Containerization Platforms for DevOps
• Containerization is a form of virtualization that packages app components within containers that run seamlessly in different IT environments. An app container stores everything required for software execution, including:
• The source code.

• Libraries.
• Run time.
• System config files.
• Dependencies.
• The speed and agility of container-based apps make this strategy a natural fit with DevOps, so let’s see what platforms you can use to start containerizing software.
• Read about container orchestration and see how experienced teams use automation to get the most value out of containerized services.
• Docker

• A natural fit with cloud computing environments as all major cloud providers have Docker support.
• Read about Docker security and see how a team should use the platform to boost security across the software life cycle.
• Kubernetes
• Kubernetes (or K8s) is an open-source platform ideal for managing containers at scale. K8s enables DevOps teams to automate the workflows and processes within environments with hundreds or even thousands of containers.
• While not as user-friendly as Docker Swarm, K8s is currently the market’s most popular container orchestration platform. The tool has a vast and loyal user base, so expect a wide selection of third-party tools if you opt for Kubernetes.

Robust monitoring and self-healing capabilities lead to excellent service availability.

• No need to tie containerized apps to a single machine–developers get to deploy to a cluster of computers, and K8s automates the distribution and scheduling of containers.
• Excellent load balancing and service discovery.
• Enables service traffic routing according to cluster topology.
• Allocates IPv6 & IPv4 addresses to services and Pods.
• Works with a range of container tools (including Docker).
• Many cloud services offer a Kubernetes-based PaaS or IaaS.
• Teams can use Helm charts to deploy multiple projects with the same custom apps.
• Unsure whether K8s or Docker is the better fit for your DevOps team? This article on Ku DevOps teams rely on various tools to ensure CI/CD, so let’s see which ones offer the best features.
• Our article on CI/CD pipelines explains the main concepts and elements of a well-organized software development workflow.
