Without continuous testing there is no continuous delivery. Everyone in DevOps talks about continuous integration and continuous delivery but those are just two ends of the DevOps pipeline. In the middle of DevOpsis continuous testing (CT), and many organizations are struggling to implement continuous testing effectively. Lab-As-A- Service (LaaS) enhances CT with dynamic on-demand self-serve test topologies. CT together with LAAS make a powerful combination that perfectly serves complex software development and delivery pipelines. Software Defined Networks (SDNs) turn the network into a flexible configurable system of software components and connections which is powerful but presents new complexities and challenges for network software development, delivery and deployments. This talk explains how DevOps best practices for continuous testing when combined with LaaS are make an excellent combination to accelerate SDN realization and operations. The talk describes people, process and products required for SDN continuous testing and online self-service continuous lab and testing services.
