Server-based architecture
involves managing and
maintaining your own servers,
while serverless architecture
utilizes cloud-based functions,
eliminating the need for server
management.
Server-based systems offer more
control and customization but
require ongoing maintenance and
infrastructure management.
Serverless architecture, on the
other hand, simplifies
development, reduces costs, and
enables rapid scalability, but may
offer less control.

Introduction to Serverless
The term “serverless” means that your code runs on servers, but you do not need to provision or manage
these servers. With serverless computing, you can focus more on innovating new products and features
instead of maintaining servers.
Another benefit of serverless computing is the flexibility to scale serverless applications automatically.
Serverless computing can adjust the applications' capacity by modifying the units of consumptions, such
as throughput and memory.
An AWS service for serverless computing is AWS Lambda.

Why serverless? • No server management
Eliminate operational overhead so your teams can release quickly, get
feedback, and iterate to get to market faster.
• Automatic scaling
With technologies that automatically scale from zero to peak demands, you
can adapt to customer needs faster than ever.
• High availability built in
With technologies that automatically scale from zero to peak demands, you
can adapt to customer needs faster than ever.
• Pay for value billing model
With a pay-for-value billing model, resource utilization is automatically
optimized and you never pay for over-provisioning.
• Build better applications, easier
Serverless applications have built-in service integrations, so you can focus on
building your application instead of configuring it.

AWS Lambda
is a service that lets you run code without needing to provision or manage servers.
While using AWS Lambda, you pay only for the compute time that you consume. Charges apply only
when your code is running. You can also run code for virtually any type of application or backend
service, all with zero administration.
For example, a simple Lambda function might involve automatically resizing uploaded images to the AWS
Cloud. In this case, the function triggers when uploading a new image.
