Organizations all over the world are in love with microservices. Teams that adopt microservices have the flexibility to choose their tools and languages, and they can iterate designs and scale quickly. However, as the number of services in the organizations continues to grow, they face challenges that can be broadly classified into two categories:

• Orchestrate the infrastructure on which the microservices are deployed.
• Consistently implement the best practices of service-to-service communication across microservices.

Kubernetes and service meshes are the solutions to those challenges. While Kubernetes is an excellent microservices lifecycle management platform, a service mesh can address the networking concerns of microservices deployed on a Kubernetes cluster. Open Service Mesh (OSM) is a lightweight and extensible cloud-native service mesh. OSM takes a simple approach for users to uniformly manage, secure, and get out-of-the-box observability features for highly dynamic microservice environments. Using the CNCF Envoy project, OSM implements Service Mesh Interface (SMI) for securing and managing your microservice applications.

With the Open Service Mesh, you can:

· Easily and transparently configure traffic shifting for deployments
· Secure end-to-end service to service communication by enabling mTLS
· Define and execute fine-grained access control policies for services
· Observability and insights into application metrics for debugging and monitoring services
· Integrate with external certificate management services/solutions with a pluggable interface

In this session, we will discuss the fundamentals of OSM, its use cases, and configurations and learn how OSM can take care of almost all of the service management issues for new and existing applications. In this demo-packed session, we will install OSM on an Azure Kubernetes Service (AKS) cluster and implement common microservices networking patterns on a set of microservices.

**Value to Attendees**

This session will help attendees get familiar with OSM concepts and patterns. Then, through a series of demos, they will learn to apply the patterns to enterprise scenarios. The following are the key takeaways from the session:

· Understand the value proposition of Service meshes
· Introduction to OSM and SMI
· Manage inter-microservice communication
· Manage the security of microservices
· Make microservices observable
· Implement common microservice networking patterns
