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 business. DevOps consists of various instruments and applied sciences, every important in bringing a software program product to life. Nevertheless, 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 common 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, aims, necessities, and techniques.

Planning and Jira go hand in hand. Jira is a well-liked undertaking administration instrument developed by Atlassian, and it’s extensively utilized in software program growth to plan, monitor, and handle initiatives. It helps numerous undertaking 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 Model Management System (VCS) that helps monitor and handle modifications to supply code over time. Git is arguably probably the most extensively 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 numerous programming languages relying on the undertaking’s necessities. Some common 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 part automates compiling supply code, linking libraries, and creating executables from the supply code.

Maven, Bazel, Ant, and Gradle are common construct instruments. 

Take a look at

Testing is a essential part 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 common methods are unit testing, integration testing, white field testing, and regression testing.

Testers use instruments that automate testing, together with common ones similar 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, check, and deployment processes, permitting seamless transitions between growth and releases.

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

Deploy

On this part, the software program goes dwell in a manufacturing atmosphere. Container know-how has taken the software program business by storm. It’s a light-weight type of virtualization that gives a solution to package deal an utility and its dependencies right into a single unit. From there, it may be simply distributed and executed constantly throughout completely different computing environments. Docker is among the hottest containerization platforms. 

Trendy 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 decreasing operational prices. AWS is a well-liked selection for internet hosting functions, companies, and sources.

Function

This part entails the administration of the infrastructure internet hosting the deployed utility. 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, similar to 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 activity automation.

Monitor

This part entails steady monitoring and evaluation of varied functions, companies, and infrastructure facets. Monitoring contains monitoring application-specific metrics, useful resource utilization, and errors.

ELK Stack and Prometheus are common 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 expertise; 300-910 DEVOPS: Implementing DevOps Options and Practices utilizing Cisco Platforms. Incomes this Skilled-level Cisco certification generally is a helpful 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 part of the DevNet Certifications Group. Then, head to Cisco U., to discover 240+ DEVOPS studying sources, together with Studying Paths, particular person programs, free tutorials, and extra.
