AWS Lambda
This document summarizes an AWS User Group Italy meeting presentation about AWS Lambda. AWS Lambda allows writing code to automatically run in response to events, allowing building applications from small functions that are triggered by changes to data in AWS services. It provides an easy way to run code without having to manage infrastructure. Lambda functions can be triggered by events in services like S3, DynamoDB, and Kinesis. With Lambda, the focus is on writing business logic rather than managing servers. Lambda automatically scales as needed to handle event loads, and customers pay only for the compute time used rather than having to pay for unused capacity. A preview of Lambda is open for people to try it out with support for S3, Kinesis and Dynam

Pick a deployment solution. 5. Plan capacity, accounting for fault tolerance, good long-term utilization, burst capability, etc. 6. Monitor 24x7x365 for capacity, health, security, etc. 7. Migrate to new instance types over time, keeping OS and language runtimes patched and up to date.
