Isolation Techniques More Isolated Threads Processes Process level Virtual Machines Java,.Net Process Groups Job Objects System Virtual Machines Hpyer-V, Xen, VMWare Operating System VMs Ex: IBM CP/CPS Containers Docker on Linux Application Virtualization App-V, VMWare ThinApp

Why Containers ? DevOps People, process & tools integration Optimized app development process Operations focused on standardized infrastructure Developers focused on building deploying and testing apps. Developers Write-once, run-anywhere Deployed as multi-tier distributed apps Powerful abstraction for microservices Operations Familiar deployment models Standardized environments for development, QA and production. Abstract the differences in OS distributions and underlying infrastructure Higher utilization and compute density Rapid scale-up / scale down
