The phrase “DevOps” means a lot of different things to different people because the discussion around it covers a lot of ground. People talk about DevOps as developer and operations collaboration, integration, automation, and the measurement of cooperation between software developers and other IT professionals.
In this blog, I’ll focus on collaboration between software developers and other IT professionals.
Typically, there is a gap in between developers, QA, and system admins while troubleshooting. This is where DevOps comes into the picture, because it is where developers, Quality Assurance, and system administrators work together to deliver the application at the speed of the business.
Troubleshooting as a skill is a logical, systematic search for the source of a problem in order to solve it so the product or process can be made operational again.
In a DevOps organization, everyone on the team is responsible for some level of troubleshooting. A developer troubleshoots bugs in their software, a system admin troubleshoots problems in servers and networks, and the QA team spends time first finding problems and then trying to locate the root cause. When everyone on the DevOps team uses the same proven troubleshooting techniques, the whole team benefits.
An application performance issue can be seen in any organization and multiple things, including errors in the web server, code, database, server, or network, may cause one. First, you must find the cause of the problem. Sometimes, it’s inflexible to come to a conclusion by following a step-by-step procedure.
Because performance testing is an iterative process, it’s essential to document the test results and the configuration settings for all iterations.
