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

Timer function apps


The timer function apps run at configurable intervals. The time at which the function should execute is defined through a CRON expression. The CRON expression is composed of six fields: {second} {minute} {hour} {day} {month} {day of the week}. These fields, separated by white space, can contain any of the allowed values with various combinations of the allowed characters for that field. For example, to trigger your function every 15 minutes, your scheduling CRON expression should be set to: 0 */15 * * * *.

Timer function apps are generally used to send information to other systems. They don't generally return information and write the progress of the operation to logs. This category of functions is typically built to clean up or manage reconcile or manage data at regular intervals. Timer functions are also used for checking the health of other services by pinging them at regular intervals. Just like any other category of functions, these functions can be combined with...
