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

Architecture of Microservices-based systems


Many of us have been curious about the representation of a Microservice by a hexagon. The reason for this is the inspiration behind the architectural pattern that drives Microservices – the hexagonal architecture. This pattern is also popularly known as ports and adapters in some parts of the globe. In a hexagonal architecture pattern, the code application logic is insulated with an isolation perimeter. This insulation helps a Microservice be unaware of the outside world. The insulation opens specific ports for establishing communication channels to and from the application code. Consuming applications can write adapters against these ports to communicate with the Microservice. The following diagram illustrates a hexagonal pattern for a Microservice:

Hexagonal architecture

Protocols in the case of a Microservice architecture are usually APIs. These APIs are exposed using popular protocols for ease of consumption. Hexagonal architecture lets the Microservice...
