Introduction to AWS Lambda
• Service based on docker
containers
• Also called Function as a Service
• Available in Node.js (JavaScript),
Python, Java (Java 8 compliant)
and C # (.NET Core), and Go.
• Cost Involved:
- First 1 million requests free
- $0.20 per 1 million requests

5.
Serverless Architectures
• Distribution of API Calls into
Functions
• Usage of external services from
cloud to allocate data
• Pay as you go model

Chalice
• Integrates well with other AWS
Services
• Can deploy using chalice deploy
• Built using Python
• Other Frameworks are
Serverless (JAWS), Zappa etc

9.
Monitoring
• Individual Lambda can be
monitored only for last 24 hrs
• Use AWS Services like
CloudWatch & CloudTrail
• IOPipe
• Datadog

10.
API Performance Measurements
• Jmeter
• Use of Curl

11.
Other Options
• Azure Functions
• GCP Functions
• Oracle Cloud Functions
• OpenWhisk
• Iron.io
• Webtask.io
• Nuclio

Learnings
Pros
• Serverless is really powerful !
• Great Performance
• Highly Scalable
• Low Cost
• Stateless
Cons
• Monitoring and Debugging is
hard
• Lack of Fine Grained Control
• Cold start issues
• Timeout Issues
• Vendor Lock-In
