Sail in the cloud - An intro to Istio commit
•
1 like•277 views
Microservices architecture has changed how companies develop and deploy applications. This change has affected testing process as well. New techniques have emerged and others have been enhanced. Does your organization wish to achieve unicorn like speed? With N deploys per day? Or a lead time (time to business value from idea to production) measured in days/weeks instead of months/years? In this session, we will not only describe how to use Istio and Kubernetes but actively demonstrate 3 specific techniques that you can use immediately following the session. Currently, Istio is gaining a lot of traction as service-mesh implementation for Kubernetes. In this session, we are going to explore how to install Istio, and how to use it to release new versions of our services correctly.
