This talk will introduce Stateful Serverless computing for enterprise workloads, with fully managed compute, storage, and event routing.

Introduction to presentation - 0:00

Evolution of cloud computing. Serverless is the new computing paradigm. - 0:23

Chart: More and more of the cloud platform stack is becoming the responsibility of cloud vendors - 2:01

Benefits of serverless computing: Auto-scaling, Faster time to market, Pay-as-you-go (no idle capacity), No server/VM/container management. Results in faster time-to-market and fewer development costs. - 3:13

Definitions. Stateful application saves data about each client session and uses that data the next time a client makes a request, whereas Stateless application does not save client data generated in one session for use in the next session with that client. - 4:13

Berkeley prediction: Serverless computing will grow to dominate cloud computing, if key issues are solved - 4:36

Issue #1: Inadequate storage for fine-grained operations - 5:11

Issue #2: Lack of fine-grained coordination - 5:40

Issue #3: Poor performance for standard communication patterns - 6:14

Issue #4: Lack of predictable performance - 6:48

What is missing from Serverless (Low latency storage, function-to-function networking, real-time scheduler, serverless dataflow graphs (SDGs)) - 7:29

What kind of applications does this enable? - 8:10

Requirements for Serverless in the Enterprise - 8:47

Requirement 1. Stateful Serverless (Declarative approach for automatic state management, automatic data backup, performance and cost optimizations are built-in) - 9:13

Why can’t you use individually managed services from cloud vendors? Serverless Memory/Storage - 10:30

Requirement 2. Developer experience. One experience from the desktop to the browser and cloud. - 12:35

Enter Nimbella Serverless: 60 second onboarding experience - 13:39

Monitoring, Logging, Tracing out of the box - 14:04

Requirement 3. Portability: Multi-cloud and Hybrid Cloud. Code once, Run Anywhere. Same developer experience across any cloud. - 14:11

Based on open-source (Apache OpenWhisk), built for Enterprise scale - 15:11

Focus on value creation, not infrastructure management - 15:27

Walking through a demo Stateful Application: OCR - 15:46

Showing the workflow behind it - 18:06

Stateful Serverless examples: - 19:52

Ways to connect and try Nimbella (, - 20:05

Concluding remarks and contact - 20:23
