You’ve probably heard the term DevOps a lot. But why, exactly, has DevOps Team started getting a lot of attention? And when did this happen?
Although it's not always easy for Dev and Ops to collaborate together — as the Development(Dev) team focuses on functionality and the Operation(Ops) team focuses on security and performance — working together improves overall operations.
DevOps leads to improved business agility by building a bridge between not just development and operation, but also testing, DBAs, security, and architecture. From a business perspective, the main goal of DevOps is to make the client happy by delivering software quickly and with minimal errors. DevOps is the middle ground of quality assurance, operations, and development.
Periodic Table of DevOps Tools
There are quite a few different types of DevOps tools, and they’re categorized below. All the categories contain Open Source, paid, or enterprise tools.
Source Code Management Tools(SCM)
Version Controlling is the main concern when developers don’t overwrite changes by getting the newest version of a file. SCM tools provide both coordination and the ability to work concurrently on files.
Open Source SCM Tools include: Git, GitLab and Subversions.
Database Management Tools
Database Management Tools are used for tracking, managing, and applying database schema changes. All changes to the database are stored in text files (XML, YAML, JSON or SQL) with its “author” tag. This allows for multiple developers to work in the same environment.
The main Open Source Tool is Liquibase.
In large projects, it’s very difficult to keep the track of what needs to be built, and in what sequence. So for this, we need a consistent approach for automation.
The Open Source Tools for this are, ANT, Gradle, and MSBuild.
Continuous Integrations Tools
When the team member submits changes to version control, continuous integrations automate the building and testing of code, so that the new version doesn’t cause any effect to the old Repository.
These Open Source Tools include: Jenkins, TRAVIS CI, CRUISECONTROL.
Repository Management Tools
The Repository Management process is used to manage packaged binary software artifacts. It supports resource isolation features, and an knowledge of metadata is required for the artifacts.
Open Source Tools include Artifactory and Nexus.
QA takes a critical role in the entire development cycle — from finding bugs to recommending changes.
Some Open Source Tools for this are FITNESSE, Cucumber.js, and Mocha.
For Continuous Deployment (CD), the process should be automated. Deployment tools allow you to see which changes have broken the application.
Open Source Tools include Otto, SmartFrog, and Rundeck.
When a software is moved from one computing environment to another, we use Containerization Tools. Containers consist of an entire application with a multitude of dependencies and Libraries.
These Open Source Tools are: Docker, rkt, Mesos, Nomad
PaaS tools grant access to platforms that let developers build applications online, where IaaS tools provide virtual hardware.
This Open Source Tool is OpenStack.
Release Management Tools
The main goal of DevOps is to release more reliable applications faster and more frequently. Release management is basically focused on the coordination of multiple releases.
These Open Source Tools are Artifactory and Nexus.
Collaboration, Monitoring, Logging and Security Tools
Some concerns of DevOps to monitor are, logging and collaborating our developments, resources, and performing with a high level of security.
Open Source Tools for logging is Logstash, security tools include Snort and Tripwire, and build tools include Maven, Make, and Rake.
DevOps is not about simply learning the tools, it’s about a culture that adapts. And ultimately results in improved speed, quality, security, and much more. In the end, agility is vital to a successful DevOps team, so ensuring that they have the tools they need to be agile, productive, and engaged is imperative.
