Overview of this book

This Learning Path helps you understand microservices architecture and leverage various services of Microsoft Azure Service Fabric to build, deploy, and maintain highly scalable enterprise-grade applications. You will learn to select an appropriate Azure backend structure for your solutions and work with its toolkit and managed apps to share your solutions with its service catalog. As you progress through the Learning Path, you will study Azure Cloud Services, Azure-managed Kubernetes, and Azure Container Services deployment techniques. To apply all that you’ve understood, you will build an end-to-end Azure system in scalable, decoupled tiers for an industrial bakery with three business domains. Toward the end of this Learning Path, you will build another scalable architecture using Azure Service Bus topics to send orders between decoupled business domains with scalable worker roles processing these orders. By the end of this Learning Path, you will be comfortable in using development, deployment, and maintenance processes to build robust cloud solutions on Azure. This Learning Path includes content from the following Packt products: • Learn Microsoft Azure by Mohamed Wali • Implementing Azure Solutions - Second Edition by Florian Klaffenbach, Oliver Michalski, Markus Klein • Microservices with Azure by Namit Tanasseri and Rahul Rai

Service proxy


 

 

Problem

With Microservices hosted remotely, it is inefficient to instantiate a Microservice instance unless and until they are requested for by the client. During design/development time, this demands for a substitute object for the client to integrate with. Also, with cloud offering the ability to host multiple instances of Microservices across the globe, it is best that the deployment and implementation details are hidden from the client. Tightly coupled, deployment location aware communication can often result in service outages if the service deployment is relocated.

Following is an illustration of this scenario:

Service proxy (Problem)

Solution

Service proxy is an implementation pattern which solves a communication problem. Service proxy helps in abstracting the service implementation from the interface definitions. This lets you change the service implementation without affecting the contracts with the clients. To enable communication with an Actor or a Microservice, a client...
