In my earlier weblog, The Rise and Rise of DevOps Adoption, I explored the outstanding rise in reputation of DevOps and the speedy adoption of DevOps practices throughout the tech business. DevOps consists of numerous instruments and applied sciences, every important in bringing a software program product to life. Nevertheless, this abundance of decisions may be overwhelming for aspiring DevOps engineers.
On this weblog, I’ll define a complete DevOps roadmap and delve into the roles of standard DevOps instruments at every stage of the event and operational processes.
Plan
The strategy planning stage lays the muse for any software program product, defining the scope, goals, necessities, and methods.
Planning and Jira go hand in hand. Jira is a well-liked mission administration software developed by Atlassian, and it’s broadly utilized in software program improvement to plan, monitor, and handle initiatives. It helps varied mission administration methodologies, together with Agile, Scrum, Kanban, and extra.
Code
The coding section entails writing and managing the supply code.
As a number of builders collaborate on bringing software program to life, we use a Model Management System (VCS) that helps monitor and handle adjustments to supply code over time. Git is arguably essentially the most broadly used VCS that maintains a supply code repository and provides branching and merging capabilities.
Builders comply with design patterns to translate necessities into programming code. This code may be written in varied programming languages relying on the mission’s necessities. Some standard programming languages throughout the business are Java, JavaScript, C++, Python, and Go.
Construct
Subsequent, we have to convert our high-level code to binary, since computer systems solely perceive the language of ones and zeros. The construct section automates compiling supply code, linking libraries, and creating executables from the supply code.
Maven, Bazel, Ant, and Gradle are standard construct instruments.
Check
Testing is a important section to fulfill high quality and reliability requirements. There are a number of testing methods to make sure the product meets consumer expectations and performs as supposed. Just a few standard methods are unit testing, integration testing, white field testing, and regression testing.
Testers use instruments that automate testing, together with standard ones reminiscent of Selenium, SonarQube, PyTest, and Cucumber.
Launch
At this stage, software program is ready for deployment and launched to prospects. The combination and deployment course of is automated and pipelined into a steady integration and steady supply/steady deployment (CI/CD) pipeline. CI/CD pipelines automate the construct, check, and deployment processes, permitting seamless transitions between improvement and releases.
GitLab CI/CD, Jenkins, and Travis CI are standard instruments for automating software program releases.

Deploy
On this section, the software program goes reside in a manufacturing setting. Container know-how has taken the software program business by storm. It’s a light-weight type of virtualization that gives a technique to bundle an software and its dependencies right into a single unit. From there, it may be simply distributed and executed persistently throughout totally different computing environments. Docker is without doubt one of the hottest containerization platforms.
Fashionable deployments are additionally carried out by way of cloud suppliers utilizing IaaS, PaaS, and SaaS choices. Cloud deployments assist organizations entry a big quantity of storage and disc area whereas lowering operational prices. AWS is a well-liked alternative for internet hosting purposes, companies, and assets.

Function
This section entails the administration of the infrastructure internet hosting the deployed software. The favored alternative for managing containers is Kubernetes (K8). It helps automate containerized purposes’ deployment, scaling, administration, and operation.
A number of infrastructure automation instruments, reminiscent of Terraform and Ansible, additionally come into motion at this stage. Terraform gives and manages infrastructure assets, whereas Ansible focuses on configuration administration, software deployment, and job automation.

Monitor
This section entails steady monitoring and evaluation of varied purposes, companies, and infrastructure features. Monitoring consists of monitoring application-specific metrics, useful resource utilization, and errors.
ELK Stack and Prometheus are standard instruments to observe deployed purposes.
Begin your DevOps journey
Cisco provides a Cisco Licensed Specialist – DevOps certification.
