Patterns to Build Stateful Apps with Serverless - Tanmai Gopal, Hasura
Serverless computing has gained increasing popularity amongst developers, who are promised an experience of finally being able to Just Write Code. Serverless providers make this possible by forcing developers to remove "state" from their business logic. Serverless code cannot access disk or share in-memory data with concurrent invocations. This makes it easy for infrastructure solutions to provide on-demand scaling, but makes it hard for developers to build "real" applications.

In this talk, Tanmai will review different architectures, solutions and tools in the ecosystem to solve 3 common stateful problems that developers face. 1) Accessing data 2) Persisting data 3) Sharing data across concurrent executions.

This talk will focus heavily on "brownfield" and incremental adoption type use-cases, like mobilizing existing data/state and adding serverless to existing stateful applications.

3factor app: An Accessible Design Pattern for Serverless - Tirumarai Selvan, Hasura
In this talk, I will showcase a pattern involving realtime graphQL, event-driven programming and serverless, called the 3factor app, to build a complex application end-to-end. The 3factor pattern is a super accessible pattern for every level of developer to start developing modern apps on serverless. We will see where traditional monolithic architectures fall short and how to build scalable and reliable apps using this pattern.

Specifically, we will build a food ordering application: a complex application with multiple steps & intricate workflows in the 3factor style. We will especially look at the advantages of using 3factor: from infinite scalability to uninterrupted disaster recovery. We will talk about the stateful aspects of serverless as well. Finally, we will load our application with 10k requests and witness serverless in its full glory.

Serverless Machine Learning Inference with KFServing - Clive Cox, Seldon & Yuzhui Liu, Bloomberg
Putting machine learning models into production is a challenging task for data scientists and devops within an organization. In this talk we will discuss how KFServing builds on top of the KNative project to provide serverless machine learning inference. It provides simple abstractions for deploying standard and custom machine learning models and updating them via canaries. Serverless technology helps to provide painless auto-scaling and scale to zero functionality over complex GPU and CPU based components. However, serverless and machine learning inference do have their challenges especially in latency critical environments and we will discuss some of those challenges as well as the future prospects for the use of serverless within machine learning.

Low-Latency and Session-Oriented Serverless Workflows - Manuel Stein & Paarijaat Aditya, Nokia Bell Labs
Creating latency sensitive applications with serverless computing is challenging. High function invocation overhead and slow access to application state are typically the two main hurdles. In this presentation, we explore alternate design points for FaaS platforms that reduce invocation overhead by co-locating multiple functions of a workflow inside a single container and isolating concurrent function invocations at the process-level. In addition, we examine the use of persistent, addressable functions to maintain application state across function invocations where needed.

The State of Serverless - Jeremy Garcia, Datadog
In less than five years, AWS Lambda has been adopted by nearly half of companies with infrastructure in AWS. In this talk, we'll examine the serverless usage of thousands of Datadog customers to provide a look at how (and how much) serverless is being used in the real world.

You'll leave with a better understanding of how serverless technologies are being adopted, what other technologies are being adopted, as well as best practices and trends we've seen emerge. There are even some surprises along the way.

WebAssembly + OpenFaas, the Universal Runtime for Serverless Functions - Ramiro Berrelleza, Okteto
WebAssembly was initially created as a sandbox for the Web. It was designed to be lightweight, portable and compatible with most programming languages. Given these characteristics, it's no surprise that a lot of people are starting to take it outside the browser and into the realm of desktop and cloud applications.

In this talk I'll discuss why WebAssembly is perfectly suited as a runtime for serverless functions. I'll discuss how WebAssembly can be used to build serverless functions, how it compares with Docker and other runtimes and how we can leverage it to make our functions more portable and faster to start.

I'll finish with a demo of how we can build functions in different languages, compile them to portable WebAssembly binaries and then use OpenFaaS to manage and deploy them the same way we do with traditional functions.

Serverless Beyond FaaS - Vaclav Turecek, Microsoft & Hongchao Deng, Alibaba Cloud
Interest in serverless computing has increased exponentially over the last five years, yet Gartner estimates that less than 5% of enterprises adopted a serverless computing model in 2019. Definitions for serverless computing vary, but in practice it hasn’t moved much beyond Functions-as-a-Service. While this event-driven architecture works for many use cases, we believe in a broader vision for serverless computing where entire cloud-native applications can run on serverless infrastructure.

In this session, we’ll show how we are designing the Open Application Model to allow developers to describe complete cloud-native applications with operational characteristics in an infrastructure-agnostic way. In doing so, we hope to broaden the scope of what a serverless application can be.

Serverless Messaging Patterns that Make or Break your App at Scale - Jeff Hollan, Microsoft
Serverless enables you to quickly write event driven code to trigger on different messages. But where and how those messages are delivered can make all the difference in the world. When using serverless in production, there are major considerations when deciding between queues and streams, events and messages, and order or unordered processing.

Azure Functions has been serving thousands of customers with billions of executions every day. This session will share out some of the common messaging patterns and capabilities, and the dos and donts of event driven at scale.
