erverless computing allows you to build and run applications without the need for provisioning or managing servers. With serverless computing, you can build web, mobile, and IoT backends; run stream processing or big data workloads; run chatbots, and more. In this session, we will learn how to get started with Serverless computing using AWS Lambda, which lets you run code without provisioning or managing servers.

Challenges with monolithic software
Long
Build/Test/Release
Cycles
(who broke the build?)
Operations
is a nightmare
(module X is failing,
who’s the owner?)
Difficult to
scale
New releases
take months
Long time to add
new features
Architecture is
hard to maintain
and evolve
Lack of innovation
Frustrated customers
Lack of agility

How it works?

17. © 2019, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Using AWS Lambda
Bring your own code
• Node.js, Java, Python, C#,
.Net Core 2.0, GO, Ruby
• Bring your own libraries
(even native ones)
• Layers
Simple resource model
• Select power rating from
128 MB to 3 GB
• CPU and network
allocated proportionately
Flexible use
• Synchronous or
asynchronous
• Integrated with other
AWS services
Flexible authorization
• Securely grant access to
resources and VPCs
• Fine-grained control for
invoking your functions

18. © 2019, Amazon Web Services, Inc. or its Affiliates. All rights reserved.
Using AWS Lambda
Authoring functions
• WYSIWYG editor or
upload packaged .zip
• Third-party plugins
(Eclipse, Visual Studio,
PyCharm)
Monitoring and logging
• Metrics for requests,
errors, and throttles
• Built-in logs to Amazon
CloudWatch Logs
Programming model
• Use processes, threads,
/tmp, sockets normally
• AWS SDK built in (Python
and Node.js)
Stateless
• Persist data using
external storage
• No affinity or access to
underlying infrastructure

Benefits of AWS Serverless
• Reduces new-account provisioning time from
2 weeks to 10 minutes
• Provides complete visibility into all accounts’
security profiles
• Ensures uniform configurations and controls
Faster Time to Market
Autodesk goes Serverless in the AWS Cloud, reduces account-
creation time by 99%
Going Serverless with AWS
Lambda relieves us from
managing servers and lets
us concentrate on building
features.
