- 15. 15 Supporting Fast-IT using Fast deploy architecture
- 16. What is fast deploy • Fast code deployment • < 5 minutes per DC for 30+ bundles (earlier 45 minutes) • Resumes deploy from where last stopped/failed • True ‘Zero’ Downtime to End User • No disruption to even the requests in progress • Sanity Test support on the deployment • Sanity users use the same domain as the end users
- 17. Fast APP CODE deploy • Udeploy pulls the required bundles from Artifactory for a given build • First and last bundle go in sequence • Rest of the bundles go in parallel • Tool retries deploy only bundles that failed • The deployments progress parallel to all AEM in a DC pkgmgr
