✦ Synopsis

Deliver microservices architecture, step-by-step: from defining business problems through development, deployment, and monitoring

Increasingly, organizations are modernizing application development by integrating open source technologies into a holistic architecture for delivering high-quality workloads to the cloud. This is a complete, step-by-step guide to building flexible microservices architecture by leveraging Microsoft Azure cloud services, together with key open source technologies such as Java, Node.JS, .NET Core and Angular. Through a realistic case study project, expert Microsoft engineers Ovais Mehboob Ahmed Khan and Arvind Chandaka guide you through every step of technical implementation required to achieve value: establishing end-to-end infrastructure, developing cloud-native applications, automating deployments, monitoring operations, and more.

Microsoft engineers Ovais Mehboob Ahmed Khan and Arvind Chandaka show how to:

• Define application features and business requirements, and map them onto microservices using modeling techniques
• Design microservices solution architecture that enables high-quality workloads
• Develop an application front-end, and build microservices with open source technologies
• Leverage Azure Kubernetes Services for Docker container orchestration
• Use various patterns to build reliable and resilient microservices
• Enforce microservices app security, and use Azure AD B2C for user authentication/authorization
• Establish an API gateway that provides a unified “front door” to back-end microservices
• Set up continuous integration and deployment with Azure DevOps
• Monitor microservices with Azure Monitor and Azure Application Insights

About This Book
