Exploring serverless architecture: the key to building more efficient backend systems.

All you need to know about #serverless

You may have heard the phrase "server less" more than once.

Lets learn
- What it is?
- Why it is called Servers?
- How does it works?
- Example?
- why it is important to learn serverless?

What is serverless, and is it actually serverless?

An application running "serverless" does not necessarily mean that servers are not used.

To run any application, we need servers. without servers applications won't get executed.

What makes this serverless?

it basically means developers do not have to oversee and administer the server. Cloud manages the server independently on behalf of the developers.

Developer only need to develop the application, server & configuration all will be handled by cloud

How does serverless works?

Basically, everything in a serverless architecture operates using an event-driven model

When an application event occurs, such as an HTTP call or a message from a queue, the cloud receives a signal to launch the application in a stateless container

What are some serverless platform examples?

Every significant cloud provider offers a serverless platform.
We call
- AWS (Lambda)
- GCP (Google cloud function)
- Azure (Azure Function)

Is understanding serverless design necessary?

Yes, the majority of use cases utilise serverless design, which offers benefits like.

- Automatic scale and descale
- Less configuration
- Save cost
- High availability
- Running instances only when needed

Example of backend applications runs on serverless.
- Schedular
- Notification System
- recurring billing
- Archival files
- many more....

That's a wrap !
