Moving applications to the cloud brings new challenges for both developers and operators. Developers will use microservices to build their applications, while operators will need to manage large numbers of microservices deployments. Istio will reduce the complexity of such microservices by providing a service mesh that can transparently integrate into existing distributed applications and provides a way to securely connect and monitor microservices. In this workshop we will first discuss the architecture of Istio, then we will install it into an existing Kubernetes cluster. Once we have Istio in place, we will deploy a sample application and will have a look at some of the functionalities of Istio.
