Serverless -  Your Gateway to the Cloud!
What is
Serverless?
Serverless computing (or serverless for short), is an
execution model where the cloud provider (AWS, Azure, or
Google Cloud) is responsible for executing a piece of code by
dynamically allocating the resources.
And only charging for the amount of resources used to run
the code.

Serverless -  Your Gateway to the Cloud!
- Continuous scaling
- Fault tolerance
built-in
- Pay for value
- Zero maintenance
- Platform independence
- Consistent runtime
environment
- Higher resource utilization
- Easier and faster
deployments
- Isolation and sandboxing
- Start speed (deploy in
seconds)
- Requires “guess” planning
- Lives for years
on-premises
- Heavy investments
(capex)
- Low innovation factor
- Deploy in months
- Hardware independence
- Faster provisioning
speed (minutes/hours)
- Trade capex for opex
- More scale
- Faster speed and agility
- Reduced maintenance
