In my earlier weblog, The Rise and Rise of DevOps Adoption, I explored the outstanding rise in reputation of DevOps and the fast adoption of DevOps practices throughout the tech trade. DevOps consists of numerous instruments and applied sciences, every very important in bringing a software program product to life. However, this abundance of selections might be overwhelming for aspiring DevOps engineers.
In 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 starting 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 venture administration software developed by Atlassian, and it’s extensively utilized in software program improvement to plan, monitor, and handle initiatives. It helps numerous venture administration methodologies, together with Agile, Scrum, Kanban, and extra.
Code
The coding part entails writing and managing the supply code.
As a number of builders collaborate on bringing software program to life, we use a Version Control System (VCS) that helps monitor and handle modifications to supply code over time. Git is arguably essentially the most extensively used VCS that maintains a supply code repository and affords branching and merging capabilities.
Developers comply with design patterns to translate necessities into programming code. This code might be written in numerous programming languages relying on the venture’s necessities. Some widespread programming languages throughout the trade are Java, JavaScript, C++, Python, and Go.
Build
Next, we have to convert our high-level code to binary, since computer systems solely perceive the language of ones and zeros. The construct part automates compiling supply code, linking libraries, and creating executables from the supply code.
Maven, Bazel, Ant, and Gradle are widespread construct instruments.
Test
Testing is a crucial part 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 widespread methods are unit testing, integration testing, white field testing, and regression testing.
Testers use instruments that automate testing, together with widespread ones akin to Selenium, SonarQube, PyTest, and Cucumber.
Release
At this stage, software program is ready for deployment and launched to prospects. The integration 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
In this part, the software program goes dwell in a manufacturing setting. Container know-how has taken the software program trade by storm. It is a light-weight type of virtualization that provides a technique to bundle an utility and its dependencies right into a single unit. From there, it may be simply distributed and executed constantly throughout totally different computing environments. Docker is likely one of the hottest containerization platforms.
Modern deployments are additionally carried out by 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 selection for internet hosting purposes, companies, and assets.

Operate
This part entails the administration of the infrastructure internet hosting the deployed utility. The widespread selection for managing containers is Kubernetes (K8). It helps automate containerized purposes’ deployment, scaling, administration, and operation.
Several infrastructure automation instruments, akin to Terraform and Ansible, additionally come into motion at this stage. Terraform offers and manages infrastructure assets, whereas Ansible focuses on configuration administration, utility deployment, and process automation.

Monitor
This part entails steady monitoring and evaluation of assorted purposes, companies, and infrastructure facets. Monitoring consists of monitoring application-specific metrics, useful resource utilization, and errors.
ELK Stack and Prometheus are widespread instruments to watch deployed purposes.
Start your DevOps journey
Cisco affords a Cisco Certified Specialist – DevOps certification. You earn the DevOps Specialist certification by passing one examination, designed to evaluate your DevOps expertise; 300-910 DEVOPS: Implementing DevOps Solutions and Practices utilizing Cisco Platforms. Earning this Professional-level Cisco certification could be a invaluable asset in showcasing your experience in DevOps and enhancing your profession alternatives in tech.
Get began by visiting the Cisco Learning Network to obtain the 300-910 DEVOPS examination matters be a part of the DevNet Certifications Community. Then, head to Cisco U., to discover 240+ DEVOPS studying assets, together with Learning Paths, particular person programs, free tutorials, and extra.
