Functions require computing resources

[tanaakhktnntrihmh@]

A function is a small, discrete unit of code that performs a single task. such as CPU and memory to run. Cloud providers allocate these resources only when needed. Cloud providers create a temporary environment for serverless functions to run.

Certain events can trigger or cause a unit of code to run. For example, if a user selects a button in your application, an event might run. This request would trigger a function that reads a database and returns the relevant information to the user.

Extension Request
The more requests a function receives, the more resources it needs to run. Serverless nigeria whatsapp lead platforms monitor load and continuously allocate cloud resources at nearly unlimited scale. As a result, a single serverless function can handle a million requests without changing the code.


Once a function stops receiving requests, the cloud provider shuts down the associated infrastructure to save costs. Cloud providers allocate resources only when needed. If there is no usage, the environment resources can be scaled down to zero.
