This eBook will cover various concepts of Azure Functions, its development, deployment, management, and monitoring. Microsoft launched Azure Function early 2016 as a preview, and it became generally available mid-November of 2016.

The benefits of Azure Functions in a nutshell are:

• Managed service by Microsoft, thus less DevOps.
• Focus on business logic, deliver solutions faster.
• Lower effort to experiment – ‘built fast fail fast.’
• Only pay what you use, i.e. for each execution.
• Reusability of functionality.

Some of the common scenarios for Azure Functions can be:

• Timer-based processing
• Azure service event processing
• SaaS event processing
• Serverless web application architectures
• Serverless mobile backends
• Real-time stream processing
• Real-time bot messaging
