Introduc.on:WhatisDevOps

DevOps (a clipped compound of "development" and "operations") is a culture, movement or practice that emphasizes the collaboration and communication of both software developers and other information-technology (IT) professionals while automating the process of software delivery and infrastructure changes. https://en.wikipedia.org/wiki/DevOps

TheApproach:Solu.onsArchitecture•  Gatherrequirements•  PicturethearchitectureofaSoluDon•  IdenDfylogicalcomponents(basedondomain)•  tomodelwithWSO2products

TheApproach:L0Architecture(Example)

TheApproach:Ac.ve-Passivedeployment(Example)

TheApproach:Ac.ve-Ac.vedeployment(Example)

TheApproach:CapacityPlanning•  DetermineVolume(s)tobehandled

–  throughput,concurrency,latency,averagedatapacketsize•  Checkthecapacityofaproductinstance•  Determinehowmanyinstancesrequiredinacluster•  Consideravailabilityandfailoverscenarios

Deploymentofproducts•  Choosedeployment-modeandinfrastructure

–  eg.on-premise/cloud,LINUXboxes/AmazonAWS•  ReadWSO2hardwarespecifica.on•  Preparemachines/virtual-machines•  ExtractbinarypackagesofWSO2products•  Configureclustersandconstructthesolu.on
