DevOps Engineer – An Overview

A DevOps Engineer is in charge of releasing code, managing infrastructure, automating processes, CI/CD – everything together. They help collaborate closely with development and operations teams to automate software deployment, improve the chance of a successful deployment, and have a clean and efficient workflow.

Continuous Integration and Continuous Delivery (CI/CD)

• Having a good CI/CD pipeline allows easy integration of code changes and deployment of the code.
• Build software reliable and make test automation part of the pipeline.

Infrastructure as Code (IaC)

• Use IaC tools like Terraform, Ansible, CloudFormation, or other similar.

Automation

• Use automation to do repetitive tasks and processes better, faster and with less human error.
• Create and keep scripts for deployment, monitoring and general routine work.

Monitoring and Logging

• Monitoring and logging systems to monitor application and infrastructure health and performance, set up and maintain.
• Monitor your system using Prometheus or a similar tool, and set up Grafana to visualise the metrics for the log management.

Collaboration

• Due to the close relationship with software developers, system operators, and other IT staff, these codes are released and deployed.
• Culture of collaboration between development and operations teams.

Security

• We should implement security best practices in the DevOps process, such as automated security tests and vulnerability assessments.
• To guarantee compliance with security policies and procedures.

Performance Optimization

• Locate performance bottlenecks in infrastructure and applications.
• Regular performance tuning and capacity planning.

Incident Management

• Handle issues and resolutions in a manner that causes very little downtime and very little loss of business operations.
• Carry out post-incident reviews and make improvements to ensure they do not recur.
