building serverless applications with AWS

Transcript

1. building serverless applications with AWS arpee ong
2. usual requirements to run a web application • web server running: • web server (apache, nginx etc.) • preprocessor / web framework (php, python etc.) • database server running: • database (mysql, postgresql etc.)
3. common considerations to scale your web application • Provisioning Resources: • CPU • RAM • Disk Space • Network • Software Updates etc.
4. introducing aws lambda • a compute service allowing you to run your code without servers. • scaling is automatic. • you are charged with the compute time your function consumes. • inherently HA. • supports node.js, java and python.
5. introducing the serverless framework • The Serverless Framework helps you develop and deploy your AWS Lambda functions, along with the AWS infrastructure resources they require. • It's a CLI that offers structure, automation and best practices out-of-the-box, allowing you to focus on building sophisticated, event-driven, serverless architectures, comprised of Functions and Events.
6. sample application: multi-user todo application • requirements: • create users • list users • associate tasks to users • categorize tasks • mark tasks as complete • delete task
