Rather, all team members actively participate in all aspects of software development from development and test to deployment to operations, and develop a range of skills not limited to a single function. </p> <h2> SRE </h2> <p>While adopting DevOps philosophy is ideal for any software development team, the cost of adoption is quite high. <br> This is especially true for larger organizations with complex hierarchies. <br> This is where SRE comes into picture. The Ops team is transformed into SRE (Site Reliability Engineering) team who closely work with the development team towards shared objectives. Once the two teams align well, the organization could move towards DevOps culture. SRE acts as a stepping stone towards final objective of DevOps transformation. </p> <h2> DEVSECOPS </h2> <p>Infusing security at every phase of DevOps is DevSecOps. </p> Sainath L Thu, 22 Sep 2022 18:44:00 +0000 https://www.debug.school/lssainath/what-is-epel-what-are-the-instructions-to-install-and-use-it-1ni https://www.debug.school/lssainath/what-is-epel-what-are-the-instructions-to-install-and-use-it-1ni <p>RedHat company releases 2 versions of OS - Fedora a general purpose OS and Red Hat Enterprise Linux or RHEL for enterprise users.
