- What is DevOps in simple terms?
DevOps is the combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity: evolving and improving products at a faster pace than organizations using traditional software development and infrastructure management processes.
- What exactly do DevOps do?
Project management: in some cases, DevOps engineers take a lead managing the whens, wheres, hows, and whos of an IT project, making sure everyone’s clear on objectives, aware of major deadlines, and in regular contact
Designing and improving IT infrastructure: your core infrastructure might be holding you back. A DevOps engineer can identify how you can improve this to encourage collaboration and, ultimately, get your releases to market quicker.
Performance testing and benchmarking: evaluating how well and reliably systems run is a key part of a DevOps engineer’s day-to-day responsibilities.
Automation: are your releases slowed down by important but repetitive tasks? One of a DevOps engineer’s major roles is to reduce hours spent here by automating these and building useful software plugins that will lighten your software team’s load.
Optimizing release cycles: are you losing valuable time because of how your release cycles are structured? DevOps engineers look for ways to optimize your release cycles, remove hidden time drains, and introduce new ways of moving the process along (new software, for example).
Monitoring and reporting: one of a DevOp engineer’s roles is to provide feedback from production to reduce ‘time to detect’ (TTD) errors and ‘time to minimize’ (TTM) them.
Security: security-focused DevOps, or SecDevOps, is a set of best practices aimed at keeping security central to all DevOps processes. This includes automation of key processes, release schedules and infrastructure design.
- What are the list of DevOps Tools?

Discover - Mural
Plan - Jira Software , Slack
Build - Kubernetes , Docker
Infrastructure as code - Ansible , Docker , Puppet , Terraform
Source control and collaborative coding - Github
Continuous Delivery - Jenkins , Sonarsource,Bitbucket
- How DevOps and SRE are different?
DevOps Engineers are ops-focused engineers who solve development pipeline problems. Site Reliability Engineers are development-focused engineers who solve operational/scale/reliability problems. Both sets of engineers are crossing the chasm by bringing their expertise and opinions to the other side of the equation.
- What is DevSecOps?
DevSecOps stands for development, security, and operations. It's an approach to culture, automation, and platform design that integrates security as a shared responsibility throughout the entire IT lifecycle.
