You’ve reached the end of this book on building an analytics system in Azure using the Lambda architecture. Each chapter demonstrates part of the overall system. You can see flow of data through the system in figure 13.1.
- Storage account services support backups of other Azure services, disks for Azure Virtual Machines, and durable, scalable storage for web applications.
- Queues and Event Hubs decouple components of applications. Use them in other systems for scalability and asynchronous processing.
- Relational databases are used in many multi-tiered software applications. The many flavors of SQLDB allow drop-in substitution for on-premises SQL Server databases.
- Azure Data Factory can connect to external cloud services like AWS S3 and Google Cloud Storage. It can trigger web hooks, and retrieve data from websites, FTP servers, and services like Salesforce.
