To deal with the increased demand for software products, businesses worldwide have started adopting the well-known DevOps practices for rapid prototyping and delivery of software updates. Automation is an integral part of following DevOps principles. With the help of automation, DevOps excels at providing speed, consistency, and reliability of their end products.
Practicing DevOps principles alongside automation results in two significant changes within an organization -
- Increases cross-departmental collaboration.
- Increase productivity by automating repetitive mundane tasks.
What Is DevOps Automation?
The entire DevOps pipeline is divided into categories like - continuous integration, continuous testing, continuous integration, etc. DevOps automation is the practice of automating repetitive tasks throughout the categories mentioned above. The key areas of improvement after leveraging automation are -
- Eliminating the need for larger teams
- Reduces human errors
- Increase in productivity
- Speed up the DevOps lifecycle
What Processes Need to be Automated?
Almost everything in DevOps can be automated. However, factors like organizational needs and technological feasibility play a crucial role in deciding which processes are ideal for automation.
Continuous Integration/Delivery (CI/CD)
According to the core concepts of agile software development, CI/CD is the ideal process for automation. Automating CI/CD consists of all aspects of code commits, software builds, and application deployment for testing/production environments.
Automating infrastructure saves a lot of time from manually configuring, initial setup, and maintenance of networks and servers. Software-defined infrastructure with automation manages everything with minimal human interaction.
Software testing is one of the suitable areas where organizations can leverage automation to its full capability. Test automation tools like Selenium and Puppeteer make it feasible to automate tests of any kind. Automating testing can benefit drastically in the areas of unit testing, UI testing, smoke testing, etc.
Automating DevOps means incurring rapid changes in the DevOps process that are impossible to be monitored via human intervention. Automation helps in keeping track of components and changes. It achieves the above-said goals by creating automated monitoring rules. The rules are responsible for generating alerts of infrastructure availability, performance, security issues, etc.
Tools for DevOps Automation
For streamlining the automation process, every organization leverages one or more DevOps automation tools. A dedicated team of DevOps architects decides which tool is right for your organization’s needs. Few of the popular DevOps tools are -
Terraform - The tool assists developers in creating, changing, and improving infrastructure provisioning. The tool also makes it possible to create a roadmap for parallel execution while emphasizing version control.
- Support for multiple cloud platforms
- Incremental changes to source code
- Translate HCL code into JSON format
- Count of modules applied to the infrastructure
- A configuration language that supports interpolation
- Facilitates IaaC (Infrastructure as a Code) mechanism
Nagios is one of the finest DevOps automation solutions that help developers monitor infrastructure and networks. With the help of this tool, developers can identify and fix the errors existing in the current system. The tool also records events, interruptions, and failures. In addition, the network analyzer in Nagios identifies problems and optimizes bandwidth usage.
- Comprehensive monitoring of application, services, OS, and network protocols
- Provides a centralized view of the entire IT infrastructure
- In-depth and comprehensive reporting with valuable insights
- An extensive, knowledgeable, and vibrant community
- Multi-tenant capabilities and extensible architecture
- Open-source software
Buddy is a continuous integration and delivery tool that allows developers to automate software building, testing, and deployment pipelines. The tool helps developers lower the barrier to entry. In addition to all that, it utilizes delivery pipelines that the developers have created with hundreds of ready-to-use actions that you can arrange as per the need to build the final product.
- Unlimited build pipelines for developers
- Easy to set up and configure via YAML and GUI
- Support for container management tools – Docker and Kubernetes
- Continuous deployment support for GitHub, BitBucket, GitLab, etc.
- High-performance build environments
- Facilitates customization of test cases
Automation goes perfectly with DevOps if handled cautiously. According to a survey, 48% of organizations have adopted DevOps methodologies. This number is only going to increase in the future. Automation not only emphasizes reducing human errors but also helps in increasing the productivity of DevOps processes. Leveraging the right tools, thousands of companies have adopted DevOps automation. If you have any queries regarding the same, let us know in the comments below.
