rightscale webinar: continuous integration and delivery in the cloud - how rightscale does it
DESCRIPTION
Many organizations are moving toward continuous integration and delivery in order to streamline the application lifecycle and increase quality. RightScale uses cloud-focused continuous integration (CI) and continuous delivery (CD) processes in our development teams to speed new capabilities to market. In this webinar we explore three case studies on how RightScale does CI and CD in the cloud for our own development processes. Key Topics: Decode the differences between CI, CD and DevOps Combine and connect the tools needed for CI and CD Leverage cloud infrastructure for CI and CD Overcome challenges on the path to CI and CDTRANSCRIPT
