In my earlier weblog, The Rise and Rise of DevOps Adoption, I explored the exceptional rise in reputation of DevOps and the speedy adoption of DevOps practices throughout the tech trade. DevOps consists of various instruments and applied sciences, every 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 in style 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 challenge administration instrument developed by Atlassian, and it’s extensively 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 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 modifications to supply code over time. Git is arguably essentially the most extensively used VCS that maintains a supply code repository and gives branching and merging capabilities. 

Builders observe design patterns to translate necessities into programming code. This code will be written in varied programming languages relying on the challenge’s necessities. Some in style 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 in style construct instruments. 

Take a look at

Testing is a vital 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 meant. Just a few in style methods are unit testing, integration testing, white field testing, and regression testing.

Testers use instruments that automate testing, together with in style ones akin to Selenium, SonarQube, PyTest, and Cucumber. 

Launch

At this stage, software program is ready for deployment and launched to prospects. The mixing 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, take a look at, and deployment processes, permitting seamless transitions between improvement and releases.

GitLab CI/CD, Jenkins, and Travis CI are in style instruments for automating software program releases.

Deploy

On this section, the software program goes stay in a manufacturing atmosphere. Container expertise has taken the software program trade by storm. It’s a light-weight type of virtualization that provides a option to bundle an software and its dependencies right into a single unit. From there, it may be simply distributed and executed persistently throughout completely different computing environments. Docker is among the hottest containerization platforms. 

Trendy deployments are additionally carried out by means of 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 functions, companies, and sources.

Function

This section entails the administration of the infrastructure internet hosting the deployed software. The favored selection for managing containers is Kubernetes (K8). It helps automate containerized functions’ deployment, scaling, administration, and operation. 

A number of infrastructure automation instruments, akin to Terraform and Ansible, additionally come into motion at this stage. Terraform gives and manages infrastructure sources, whereas Ansible focuses on configuration administration, software deployment, and job automation.

Monitor

This section entails steady monitoring and evaluation of varied functions, companies, and infrastructure points. Monitoring consists of monitoring application-specific metrics, useful resource utilization, and errors.

ELK Stack and Prometheus are in style instruments to observe deployed functions.  

Begin your DevOps journey 

Cisco gives a Cisco Licensed Specialist – DevOps certification. You earn the DevOps Specialist certification by passing one examination, designed to evaluate your DevOps expertise; 300-910 DEVOPS: Implementing DevOps Options and Practices utilizing Cisco Platforms. Incomes this Skilled-level Cisco certification could be 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.
