What is ‘Serverless’ and ‘Function as a Service’ ?
Serverless
• Existence of servers is hidden from developers
• Code is executed on-demand in an auto-scaled, managed environment through event driven triggers
• Encourages and simplifies developing microservice-oriented solutions via functions
@nheidloff
Why Serverless for Web Applications ?
Serverless
• Often cheaper than other server-side compute options since you only pay for the exact duration your code is executing
• Easier to operate than other compute options – Example: Auto-scalability – Example: Built-in API management
• Serverless functions can be built with JavaScript skills which web developers have
