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)

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)

Lessons Learned



• Services must be as small as possible => microservices

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

Google Trends: Microservices

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

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

• 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

DEEP Frameworkhttps://github.com/MitocGroup/deep-framework

“DEEP Framework is a serverless web framework, core component of the Platform-as-a-Service that abstracts web apps and web services from specific cloud providers. This

framework enables developers build cloud-native applications or platforms using microservices architecture in a completely

serverless approach”
