What does “serverless” mean?

Not involving a server; composed only of clients.http://www.wordsense.eu/serverless

Serverless doesn’t mean servers are no longer involved. It simply means that developers no longer have to think "that much" about them. Computing resources get used as services without having to manage around physical

capacities or limits.https://www.quora.com/What-is-Serverless-Computing

• Static Assets• Same as in reference architecture• css, js, docs, images, videos + html

• Dynamic Functionality• Use JS framework (e.g. Angular)• SEO-friendly (Custom Error

Response + HTML5 History API)

• Completely Serverless• Pre-scaled• Low-cost• Low-maintenance

Demo: Setup Serverless AWS1. Security - Create IAM roles2. Front-end - Create S3 bucket - Enable static website hosting - Add bucket policy - Create CloudFront distribution3. Back-end - Create Lambda function - Upload code into Lambda - Create API Gateway endpoint4. Database - Create DynamoDB table5. Code - Load code into S3 bucket - View via CloudFront (S3 as backup)

Lessons Learned

• Serverless approach is challengingly awesome

• Frontend is restricted to JS (and JS Frameworks)• Backend is restricted to Python, Java or JS (for now)• SOA and APIs are required by design

Lessons Learned



• Services must be as small as possible

• AWS Lambda constrains• Browser limitations (on mobile devices)

What does “microservices” mean?

In computing, microservices is a software architecture style in which complex applications are composed of small, independent processes communicating with each other using language-agnostic APIs. These services are small, highly

decoupled and focus on doing a small task, facilitating a modular approach to system-

building.https://en.wikipedia.org/wiki/Microservices

• AWS Lambda scaled with no effort for us

• 70M+ invocations / day• 10K+ concurrent invocations / second

AWS Lambda in Action

• AWS Lambda scaled with no effort for us

• 70M+ invocations / day• 10K+ concurrent invocations / second

• AWS Lambda made it really easy for us

• Comes pre-scaled and charges in 100ms blocks• No under- or over-provisioning (by design)• Developers love it (especially frontend JS folks)• DevOps still in play mode (learning to build ops code)

Tips and Tricks

• AWS Lambda is continuously evolving

• Set up alarms for all 4 Lambda metrics in Amazon CloudWatch• Avoid S3 throttling by integrating S3 => SNS => Lambda• Beware of potential infinite loops

• AWS Lambda is continuously evolving

• Set up alarms for all 4 Lambda metrics in Amazon CloudWatch• Avoid S3 throttling by integrating S3 => SNS => Lambda• Beware of potential infinite loops

• Microservices are game changers

• The shorter TTL, the more secure it becomes• First, build a service or a feature• Next, break it down into microservices
