• Q&A
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

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

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
