Region A
Region B
Microservices can be hard to manage at scale

Emerging workloads are a good fit for event-driven programming
Execute logic in response to database change
Perform analytics on sensor input messages
Provide cognitive computing via chatbots
Schedule tasks performed for a short time
Invoke autoscaled APIs and mobile backends

Not a silver bullet, but this can result in
substantial savings for many workloads
New cost models more accurately charge for usage

OpenWhisk is a
cloud platform that
executes code in
response to events
OpenWhisk enables these serverless, event-driven workloads
Provides serverless deployment and operations model
Runs code only on-demand on a per-request basis
Optimized utilization, fine-grained metering at any scale
Flexible, extensible, polyglot programming model
Open source and open ecosystem (Apache Incubator)
Ability to run in public, private, and hybrid models
