#What is serverless architecture azure code

ItвЂ™s possible to build an entirely serverless app, or an app composed of partially serverless and partially traditional microservices components. With serverless, routine tasks such as managing the operating system and file system, security patches, load balancing, capacity management, scaling, logging, and monitoring are all offloaded to a cloud services provider.

In addition to the cost and efficiency benefits, serverless frees developers from routine and menial tasks associated with app scaling and server provisioning.

#What is serverless architecture azure code

The user stops paying when the code finishes executing. When an event triggers app code to run, the public cloud provider dynamically allocates resources for that code.

With serverless architecture, by contrast, apps are launched only as needed. The cloud infrastructure necessary to run an app is active even when the app isnвЂ™t being used. ItвЂ™s the userвЂ™s responsibility to scale up server capacity during times of high demand and to scale down when that capacity is no longer needed. Under a standard Infrastructure-as-a-Service (IaaS) cloud computing model, users prepurchase units of capacity, meaning you pay a public cloud provider for always-onВ server components to run your apps. Serverless apps are deployed in containers that automatically launch on demand when called. Serverless differs from other cloud computing models in that the cloud provider is responsible for managing both the cloud infrastructure and the scaling of apps.
