Beginners Guide to a Career in DevOps

ABSTRACTThe software development lifecycles moved from waterfall to agile models. These improvements are moving toward IT operations with evolution of Devops.DevOps primarily focuses on collaboration, communication, integration between developers and operations.AGILE EVOLUTION TO DEVOPSWaterfall model was based on a sequence starting with requirements stage, while development stage was under progress. This approach is inflexible and monolithic. In the agile process, both verification and validation execute at the same time. As developers become productive, business become more agile and respond to their customer requests more quickly and efficient.WHAT IS DEVOPSIt is a software development strategy which bridges the gap between the developers and IT Staff. It includes continuous development, continuous testing, continuous integration, continuous deployment, continuous monitoring throughout the development lifecycle.WHY DEVOPS IS IMPORTANT1.Short development cycle, faster innovation2.Reduced deployment failures, rollback and time to recover3.Improved communication4.Increased efficiencies5.Reduced costsWHAT ARE THE TECHNOLOGIES BEHIND DEVOPS?Collabration, Code Planning, Code Repository, Configuration Management, Continuous integration, Test Automation, Issue Tracking, Security, MonitoringHOW DOES DEVOPS WORKSDevOps uses a CAMS approachC=Culture, A=Automation, M=Measurement, S=SharingDEVOPS TOOLSTOP DEVOPS TESTING TOOLS IN 20191.Tricentis 2.
