+# What is Serverless/FaaS?
+
+Serverless is a new paradigm in computing that enables simplicity, efficiency and scalability for both developers
+and operators. It's important to distinguish the two, because the benefits differ:
+
+## Benefits for developers
+
+The main benefits that most people refer to are on the developer side and they include:
+
+* No servers to manage (serverless) -- you just upload your code and the platform deals with the infrastructure
+* Super simple coding -- no more monoliths! Just simple little bits of code
+* Pay by the milliseconds your code is executing -- unlike a typical application that runs 24/7, and you're paying
+  24/7, functions only run when needed
+
+Since you'll be running Oracle Functions yourself, the paying part may not apply, but it does apply to
+cost savings on your infrastructure bills as you'll read below.
+
+## Benefits for operators
+
+If you will be operating Oracle Functions (the person who has to manage the servers behind the serverless),
+then the benefits are different, but related.
+
+* Extremely efficient use of resources
+  * Unlike an app/API/microservice that consumes resources 24/7 whether they
+    are in use or not, functions are time sliced across your infrastructure and only consume resources while they are
+    actually doing something
+* Easy to manage and scale
+  * Single system for code written in any language or any technology
+  * Single system to monitor
+  * Scaling is the same for all functions, you don't scale each app independently
+  * Scaling is simply adding more Oracle Functions nodes
+
+There is a lot more reading you can do on the topic, just search for 
+["what is serverless"](https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=what%20is%20serverless)
+and you'll find plenty of information.
