A Developer's Guide to Building Resilient Cloud Applications with Azure

By: Hamida Rebai Trabelsi

Overview of this book

To deliver software at a faster rate and reduced costs, companies with stable legacy systems and growing data volumes are trying to modernize their applications and accelerate innovation, but this is no easy matter. A Developer’s Guide to Building Resilient Cloud Applications with Azure helps you overcome these application modernization challenges to build secure and reliable cloud-based applications on Azure and connect them to databases with the help of easy-to-follow examples. The book begins with a basic definition of serverless and event-driven architecture and Database-as-a-Service, before moving on to an exploration of the different services in Azure, namely Azure API Management using the gateway pattern, event-driven architecture, Event Grid, Azure Event Hubs, Azure message queues, FaaS using Azure Functions, and the database-oriented cloud. Throughout the chapters, you’ll learn about creating, importing, and managing APIs and Service Fabric in Azure, and discover how to ensure continuous integration and deployment in Azure to fully automate the software delivery process, that is, the build and release process. By the end of this book, you’ll be able to build and deploy cloud-oriented applications using APIs, serverless, Service Fabric, Azure Functions, and Event Grid technologies.

Exercise 2 – deploying Azure SQL Database elastic pools

If we want to manage and scale multiple databases that have various and unpredictable usage requirements, we will use Azure SQL Database elastic pools.

Pools are suitable for large numbers of databases with specific usage patterns. For a given database, this pattern is characterized by infrequent usage peaks and low average usage. Otherwise, do not place multiple databases under moderate sustained load in the same elastic pool.

Pools simplify management tasks by running scripts in elastic jobs. Elastic jobs eliminate most of the tedious work associated with numerous databases.

Pooled databases generally support the same business continuity features available with single databases.

Azure SQL Database elastic pools are a simple and cost-effective solution. They are a deployment option, which means we purchase Azure compute resources (eDTUs) and storage resources to be shared between all the included databases...
