Devops: Enabled Through a Recasting of Operational Roles
5 likes2,598 views
Delivered at CF Summit Berlin, 2 Nov 2015. One thing that everyone agrees on is that “Devops” is about reducing the friction between dev and ops. While it might not be immediately apparent, CF enables a separation of “operations” into two roles: platform ops and application ops. Platform ops is responsible for maintaining a secure platform with sufficient functionality and capacity so that application developers and application operators can perform their work. And application operators are responsible for keeping business applications up and running, so that consumers receive superior service, 24x7x365. By moving further up the stack, app operators can be far closer to the line of business owners, getting them speaking the same language. In this session we demonstrate how Cloud Foundry enables this, we talk about customers who are taking advantage of it, and we cover the tools available for each of the roles.

When I first started working on PaaS…
“For us, PaaS is a set of services aimed at developers that helps them develop and
test apps without having to worry about the underlying infrastructure. Developers
don't want to have to worry about provisioning the servers, storage and backup
associated with developing and launching an app.”
