Once deployed, serverless applications respond to demand and automatically scale as needed, as the FaaS service is metered on demand and is generally always available. Once it is done, there is no further charge.

Overview of Serverless Architecture
In a serverless model, a cloud provider spins up servers and dynamically allocates their resources to users who want to deploy code. Serverless computing is typically divided into two groups: backend as a service (BaaS) and FaaS.

BaaS provides cloud users with access to various services and automates and manages the backend portion of a web or mobile application. A cloud provider may offer authentication and encryption services, cloud-accessible databases, and access to usage data. Serverless functions are called through application programming interfaces (APIs).

But more often, when people talk about serverless, they mean the FaaS model. This is a platform that allows autonomous functions (code fragments) to be run in the cloud. It is an event-driven computing model, in which developers write application logic that is deployed in containers that are fully managed by the platform and then executed on demand. It is a triggered model, in which execution occurs dynamically in response to an event.

Functions should be designed to perform a single azerbaijan whatsapp data of work, be lightweight, and be fast to execute. Unlike BaaS, FaaS offers more control to users who build custom applications rather than relying on a library of pre-written services. The containers in which these pieces of code are deployed have the following properties:

ephemeral, they are launched only for a short time;
event triggered, they can be launched automatically when needed;
are fully managed by cloud providers, so you only pay for what you need, not for constantly running applications and servers;
They have elasticity, allowing for automatic scaling without the need to set up autoscaling groups, etc.
In a FaaS environment, applications are launched only when needed. When an event triggers application code, the provider dynamically allocates resources for that code. The user stops paying once it has finished executing. In addition to the cost-saving and efficiency benefits, serverless frees cloud users from routine tasks associated with scaling applications and provisioning servers, as well as from tasks such as operating system and file system management, security patching, load balancing, capacity management, scaling, logging, and monitoring.
