In my earlier weblog, The Rise and Rise of DevOps Adoption, I explored the exceptional rise in recognition of DevOps and the speedy adoption of DevOps practices throughout the tech trade. DevOps consists of various instruments and applied sciences, every very important in bringing a software program product to life. Nonetheless, this abundance of selections will be overwhelming for aspiring DevOps engineers.
On this weblog, I’ll define a complete DevOps roadmap and delve into the roles of widespread 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, targets, necessities, and techniques.
Planning and Jira go hand in hand. Jira is a well-liked challenge administration software developed by Atlassian, and it’s broadly utilized in software program improvement to plan, monitor, and handle initiatives. It helps varied challenge administration methodologies, together with Agile, Scrum, Kanban, and extra.
Code
The coding section includes 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 modifications to supply code over time. Git is arguably probably the most broadly used VCS that maintains a supply code repository and affords branching and merging capabilities.
Builders comply with design patterns to translate necessities into programming code. This code will be written in varied programming languages relying on the challenge’s necessities. Some widespread programming languages throughout the trade 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 widespread construct instruments.
Take a look at
Testing is a important section to satisfy high quality and reliability requirements. There are a number of testing methods to make sure the product meets consumer expectations and performs as supposed. A couple of widespread methods are unit testing, integration testing, white field testing, and regression testing.
Testers use instruments that automate testing, together with widespread ones reminiscent of Selenium, SonarQube, PyTest, and Cucumber.
Launch
At this stage, software program is ready for deployment and launched to clients. 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 widespread instruments for automating software program releases.

Deploy
On this section, the software program goes stay in a manufacturing setting. Container know-how has taken the software program trade by storm. It’s a light-weight type of virtualization that gives a solution to bundle an utility 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 likely one of the hottest containerization platforms.
Trendy deployments are additionally carried out via cloud suppliers utilizing IaaS, PaaS, and SaaS choices. Cloud deployments assist organizations entry a big quantity of storage and disc house whereas lowering operational prices. AWS is a well-liked alternative for internet hosting functions, companies, and sources.

Function
This section includes the administration of the infrastructure internet hosting the deployed utility. The favored alternative for managing containers is Kubernetes (K8). It helps automate containerized functions’ 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 sources, whereas Ansible focuses on configuration administration, utility deployment, and process automation.

Monitor
This section includes steady monitoring and evaluation of assorted functions, companies, and infrastructure elements. Monitoring contains monitoring application-specific metrics, useful resource utilization, and errors.
ELK Stack and Prometheus are widespread instruments to observe deployed functions.
Begin your DevOps journey
Cisco affords a Cisco Licensed Specialist – DevOps certification. You earn the DevOps Specialist certification by passing one examination, designed to evaluate your DevOps abilities; 300-910 DEVOPS: Implementing DevOps Options and Practices utilizing Cisco Platforms. Incomes this Skilled-level Cisco certification is usually a priceless asset in showcasing your experience in DevOps and enhancing your profession alternatives in tech.
Get began by visiting the Cisco Studying Community to obtain the 300-910 DEVOPS examination subjects be a part of the DevNet Certifications Neighborhood. Then, head to Cisco U., to discover 240+ DEVOPS studying sources, together with Studying Paths, particular person programs, free tutorials, and extra.
