In my earlier weblog, The Rise and Rise of DevOps Adoption, I explored the exceptional 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 important in bringing a software program product to life. Nonetheless, this abundance of decisions could 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 starting stage lays the muse for any software program product, defining the scope, targets, necessities, and methods.

Planning and Jira go hand in hand. Jira is a well-liked mission administration device developed by Atlassian, and it’s broadly utilized in software program improvement to plan, observe, and handle tasks. It helps varied mission 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 observe and handle adjustments to supply code over time. Git is arguably probably the most broadly used VCS that maintains a supply code repository and provides branching and merging capabilities. 

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

Check

Testing is a essential section to satisfy high quality and reliability requirements. There are a number of testing methods to make sure the product meets person expectations and performs as supposed. A couple of standard methods are unit testing, integration testing, white field testing, and regression testing.

Testers use instruments that automate testing, together with standard ones similar to 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, take a look at, 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 stay in a manufacturing atmosphere. Container know-how has taken the software program trade by storm. It’s a light-weight type of virtualization that provides a option 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 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 decreasing operational prices. AWS is a well-liked alternative for internet hosting purposes, 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 purposes’ deployment, scaling, administration, and operation. 

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

Monitor

This section includes steady monitoring and evaluation of assorted purposes, companies, and infrastructure points. Monitoring contains 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. 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.
