Rob Allen ~ @akrabat
Container deployments 1. Platform (e.g. Kubernetes) 2. Application (e.g. Cloud
Foundry) 3. Serverless (e.g. OpenWhisk) Rob Allen ~ @akrabat
Serverless? The first thing to know about serverless computing is
that "serverless" is a pretty bad name to call it. - Brandon Butler, Network World Rob Allen ~ @akrabat
AKA: Functions as a Service • A runtime to execute
your functions • No capacity planning or load balancing; just tasks being executed. • Pay for execution, not when idle Rob Allen ~ @akrabat
Use-cases Synchronous Service is invoked and provides immediate response (HTTP
requests: APIs, chat bots) Asynchronous Push a message which drives an action later (web hooks, timed events, database changes) Streaming Continuous data flow to be processed Rob Allen ~ @akrabat
Benefits • No need to think about servers • Concentrate
on application code • Pay only for what you use, when you use it • Language agnostic: NodeJS, Swift, Python, Java, C#, etc Rob Allen ~ @akrabat
Challenges • Start up latency • Time limit • State
is external • DevOps is still a thing Rob Allen ~ @akrabat
It's about value Rob Allen ~ @akrabat
When should you use serverless? • Occasional server needs on
a static site • Variable traffic levels • Additional compute without extending current platform • Responding to web hooks Rob Allen ~ @akrabat
Serverless providers Rob Allen ~ @akrabat
OpenWhisk Rob Allen ~ @akrabat
OpenWhisk OpenSource; multiple providers: IBM RedHat Adobe (for Adobe Cloud
Platform APIs) &, of course, self-hosted Rob Allen ~ @akrabat

hello hello.php --web true $ curl https://openwhisk.ng.bluemix.net/api/v1/web/ \ 19FT_demo/default/hello.json Rob Allen ~ @akrabat
What to do in your action • Compute! • Store
to database • Make API calls to other services • Store to cloud storage (S3) • Trigger other actions Rob Allen ~ @akrabat
