Sample Site | AWS Console | lab-001 | lab-002 | lab-003 | lab-004

The topics for this hands-on session will be AWS Lambda, function as a service (FaaS). During this Playground you will create a website hosted on AWS S3 using AWS Lambda and Amazon API Gateway to add dynamic functionality to the site.

Each step will be associated with a Lab to complete build on the previous lab to progress. A Completed lab website is a available for view from the link above 'Sample Site'. All labs have been tested with the US Oregon region.

A computing model where the existence of servers are hidden from developers. Within AWS eco-system Lambda is not the only serverless service. For the purpose of these labs we will look at S3, Lambda, and API Gateway to produce a functional website.

• Storage - S3
• Compute - Lambda
• Database - DynamoDB, ElasticCache
• API Proxy - API Gateway
• Analytics - AWS Kinesis
• Messaging & Queues - AWS SNS, SQS
• State Management - AWS Step Functions
• Diagnostics - AWS X-Ray

• S3 - Static Web hosting: Hosting a static website on S3 bucket.
• Lambda: Creating a lambda function, that generates a random number and another function that processes form GET and PUT requests.
• API Gateway: Using API Gateway to expose lambda function to static website hosted on S3 bucket.

• AWS Console: https://ecsd-training.signin.aws.amazon.com/console
• Username: <TBA>
• Password: <TBA>

1. Lab-001 - Build Static Website with s3 Bucket
2. Lab-002 - Sharing resources between s3 Buckets
3. Lab-003 - Web Services with Lambda
4. Lab-004 - Posting Data with Lambda

• Login to AWS account
• Permissions to create S3 Buckets
• Permissions to write and execute lambda functions
• Permission to create API Gateway
• Region: Oregon

If you attempt the labs in your own AWS account you will need to create the following roles:

• AWSS3FullAccess
• AWSLambdaFullAccess
• AmazonAPIGatewayAdministrator
• AWSLambdaExecute

Some labs will require having access to a web browser console to see Browser errors like lab-002 and labb-003 for Cross Origin Resource Sharing. Safari has these development tools built-in however they need to be enabled.

1. Safari > Preferences
2. Check 'Show Develop menu in menu bar' (see image Safari Advanced Preferences red box)
3. Safari menu bar should now show as in 'Safari Menu Bar' image below
