Core Benefits and Patterns of

Serverless Computing


No Infrastructure Concerns

● Allows teams to focus on what matters most –

the application

● Enables simplified deployment scenarios

● Removes infrastructure concerns and

undifferentiated heavy lifting from the

architecture, deployment, and support

perspective

Benefits include:

Eliminates the administrative overhead included with managing IaaS

or PaaS solutions.


Flexible and Dynamic Scalability

● Infrastructure scalability within seconds to

match the demands of any workload

● Increase developer velocity by writing less

code

● Platform integrations simplify complex

scenarios

Benefits include:

Inherently scalable to match the resource demands of any workload.


Faster Time to Market

● Improved team agility and performance

● Built-in intelligent monitoring and

analysis capabilities

● Supports multiple application patterns

including hybrid, cloud, and edge

computing

Benefits include:

Reduction in operational dependencies on each development cycle

increases teams agility to deliver value quicker.


Resource Efficiency

● Reduced infrastructure costs and elimination of

server licensing concerns

● Intelligent security management

● New paths of innovation and revenue

opportunities

Benefits include:

Leveraging serverless technologies helps organizations reduce total

cost of ownership and accelerate the pace of innovation.


Serverless Application Patterns

● Serverless functions

● Serverless containers

● Serverless workflows

● Serverless API gateways

Serverless applications enable multiple application patterns.


Case Study: Serverless

Migration of Hundreds of Single

Page Web Apps


The project

Digital marketing agency running hundreds of one-page web

applications across a fleet of Windows-based virtual machines. The

company wanted to reduce the overhead of their Virtual Machine

foot-print and implement a more modern development and

deployment process.


The challenge

● Deployment process was painfully slow

● Lack of automation required multiple manual

steps that were time consuming and error

prone

● Administrative overhead of supporting dozens

of virtual machines was a burden on the core

infrastructure team


The solution

● Re-factor the core application architectures

● Deliver web-front end through CloudFront and

S3

● Run backend code via AWS Lambda & API

Gateway

● Implement CloudWatch Events and AWS

Lambda for event-driven automation


The solution

https://go.aws/2SZuioY


The results

● Thousands in cost savings per month

● End-to-end automation reduced deployment

times by 70%

● Infrastructure team was able to spend more

time on innovative projects vs. maintaining

legacy infrastructure

Meet AWS Serverless Application Model (SAM)

• What is SAM?

• How does SAM work?

• How much does it cost?

• Is it open-source?

• My Lambda function is in Python. Does SAM support that?
