The State of Serverless Computing

2.
Agenda

3.
What is
serverless?
Build and run applications
without thinking about servers

4.
Let’s take a look at the evolution of computing
Physical servers
in data centers
Virtual servers
in data centers
Virtual servers
in the cloud

5.
Each progressive step was better
Physical servers
data centers
Virtual servers
data centers
• Higher utilization
• Faster provisioning speed
• Improved uptime
• Disaster recovery
• Hardware independence
• Trade CAPEX for OPEX
• More scale
• Elastic resources
• Faster speed and agility
• Reduced maintenance
• Better availability and fault
tolerance
Virtual servers
in the cloud

6.
But there are still limitations
Physical servers
data centers
Virtual servers
data centers
• Trade CAPEX for OPEX
• More scale
• Elastic resources
• Faster speed and agility
• Reduced maintenance
• Better availability and fault
tolerance
• Still need to administer
virtual servers
• Still need to manage
capacity and utilization
• Still need to size
workloads
• Still need to manage
availability, fault tolerance
• Still expensive to run
intermittent jobs

8.
No server is easier to manage than no server
All of these responsibilities
go away
Provisioning and utilization
Availability and fault tolerance
Scaling
Operations and management

9.
Serverless is a form of event-driven computing
Event-driven computing

Customers innovating with serverless

22.
Enterprises are achieving massive scale with Lambda
• Thomson Reuters processes 4,000 requests per second
• FINRA processes half a trillion validations of stock trades daily
• Hearst reduced the time to ingest and process data for its
analytics pipeline by 97%
• Vevo can handle spikes of 80x normal traffic
• Expedia triggers 1.2 billion Lambda requests each month

But what happens
when you have an
entire app made up
of many functions?
Composing serverless applications

41.
Meet SAM

42.
AWS Serverless Application Model (SAM)
Standard model for
representing serverless
applications on AWS
Functions, APIs, event
sources, and data stores
Simplifies deployment and
management for serverless
applications

43.
AWS Serverless Application Model (SAM)
• Natively supported by AWS
CloudFormation
• Export any function as a SAM
template
• Package and deploy SAM
templates using AWS CLI
• Open spec under Apache 2.0
for community extensions

Developer ecosystem — AWS
How do you debug distributed applications
made of multiple functions or services?
How do you gain insights into how your
functions are performing or behaving?

47.
AWS X-Ray
• Analyze and debug distributed
apps in production
• Visualize service call graph of
your app
• Identify performance
bottlenecks and errors
• Pinpoint service-specific issues
• Identify impact of issues on
users of the app
• Trace function executions
(coming soon)
