In the modern day, there is a plethora of DevOps technologies available, each with its own set of advantages. Let’s explore the leading DevOps automation technologies that are transforming software delivery and teamwork.

5.1 Jenkins

When people think of continuous integration and continuous delivery (CI/CD), they usually picture Jenkins. This open-source tool allows the automation of repetitive tasks using multiple programming languages, development tools, and code repositories due to its large plugin ecosystem. Additionally, Jenkins leverages the scripting process to customize and integrate the entire DevOps chain to make it more powerful.

5.2 Docker

Docker is one of the most important DevOps automation technologies that revolutionized application development, shipping, and running through containerization. It enables rapid deployment of development environments to create new images or update existing ones to meet specific requirements.

This has become possible because the Docker-Puppet integration involves utilizing over seven million lines of Puppet code. By encapsulating a program along with all of its dependencies in a “container,” Docker can be completely portable and very compatible with any setting.

5.3 Git

If your project requires sharing your app files’ master version with the distributed teams then using Git is very beneficial for you. Its distributed design ensures that all developers always have access to the most recent version of the code. In addition to that, Git also allows teams to monitor changes, work together on code, and connect to other tools in the DevOps pipeline.

5.4 Ansible

When it comes to managing configurations, deploying applications, and automating tasks, Ansible is a strong automation tool. It is largely used for configuration modules known as ‘Playbooks’.

Ansible uses YAML, a basic, human-readable language, which makes setup and maintenance a breeze and Playbooks are written in YAML format. So, it’s an ideal match. Ansible also offers support for cloud provisioning.

5.5 Terraform

For effective infrastructure creation, modification, and management, teams may rely on Terraform, a tool for infrastructure as code. It leverages the ‘state files’ to maintain the infrastructure of the state. Terraform is compatible with numerous public and private cloud platforms as it offers cloud infrastructure provisioning.

6. Best Practices

Here we will examine various DevOps best practices and methods for enhancing DevOps processes.

6.1 Build a Continuous Integration and Delivery (CI/CD) Pipeline

A strategy that facilitates effective collaboration among developers is the frequent integration of small batches of code into a common code repository. By introducing manageable modifications in modest increments, this method helps to maintain the repository consistently. With Continuous Integration (CI), automated builds and tests assess these small batches of changes every time, allowing for early issue identification and enhancing code quality.

Deploying your code to the environment is the next step following integration. As part of Continuous Delivery (CD), code is continually made deployable for each small batch of changes. This gives the developers a simple, automated way to submit code to production and streamlines our deployments.

6.2 Prioritize Security From the Beginning of the Project

Software security shouldn’t lag behind other considerations during development. As a new paradigm, DevSecOps encourages developers to consider infrastructure and software security from the very beginning of the software development lifecycle, building security into the architecture from the ground up and integrating it into continuous integration and continuous delivery pipelines.

Security should not be seen as an afterthought, but rather as an essential component of the process, and it should be a shared responsibility across all teams and throughout the application lifetime. Due to a rise in malicious attacks over the past few years, there has been a major emphasis on safeguarding the software supply chain recently.

When it comes to infrastructure, the smallest slip-up can lead to catastrophic failures. Because of this, you need to provide an additional policy layer that lets you manage independently of your infrastructure project, the execution of code, the modification of code, the timing and identity of code modifications, and so on. In addition to preventing unauthorized access, this enables you to set up a pipeline for automatic code reviews.

6.3 Unify the DevOps Toolchain

The process of software delivery becomes more complicated due to the lack of visibility caused by pipeline variation and toolchain fragmentation. Due to the disjointed nature of the many technologies and teams involved, there is currently no centralized method for monitoring and improving the software delivery pipeline’s efficiency in real time. The inability to transfer data among tools makes it difficult to gain a holistic understanding of your organization’s performance, despite each tool providing information regarding its performance.

This can help DevOps teams monitor, assess, and optimize their software development and delivery outcomes in real time via unified visibility of the software development process.

6.4 Encourage the Culture of Collaboration

An integral part of DevOps best practices is fostering a collaborative culture. The success of DevOps depends on the tight cooperation of many stakeholders, including development and operations teams. Open dialogue, collective accountability, and a dedication to constant development may all flourish in workplaces that prioritize teamwork. As a result, DevOps teams may enhance the dependability and quality of their goods and services while also finding and fixing problems faster. The company and its workers may both reap the rewards of a more upbeat and fruitful workplace fostered by a culture of collaboration.

6.5 Use Microservices Architecture

Organizations may enhance the adaptability, versatility, and flexibility of their systems by employing a microservices architecture. Application development, testing, and deployment are all managed separately in a microservices architecture since each service is broken down into smaller components. This approach facilitates the rapid rollout of new features and functionalities while also easing the burden of system scaling and maintenance on enterprises. Also, because problems in one service may be fixed independently of the others, microservices can enhance the resilience and reliability of systems.

7. Conclusion

DevOps Automation is the key to efficient production and deployment of high-quality code. Automating various DevOps processes reduces manual intervention which eliminates the chances of human errors. You can leverage the right automation tools and best practices to accomplish your DevOps goals quickly when you have clarity on your requirements.
