OpenWhisk is a serverless computing platform that allows for running stateless functions in response to events. It uses Docker containers to run functions (actions) that are triggered by events. The OpenWhisk system is built on a distributed architecture using virtual machines to run controller, invoker, and action containers. Functions are run securely and billed based on usage at a fine-grained level. OpenWhisk allows for building event-driven applications through its triggers, rules, and action composition model.
OpenWhisk Deep Dive: the action container modelPhilippe Suter
OpenWhisk supports actions written in JavaScript, Swift, Java and Python. In this talk, we explore the internals of OpenWhisk to learn how these actions are created, stored, and executed. We dive into the (internal) specification that makes supporting such a variety of runtimes feasible, and illustrate it by implementing, as a running example, support for a new language.

OpenWhisk - A platform for cloud native, serverless, event driven appsDaniel Krook
Cloud computing has recently evolved to enable developers to write cloud native applications better, faster, and cheaper using serverless technology.
OpenWhisk provides an open source platform to enable cloud native, serverless, event driven applications.
This presentation lays out the technical and business drivers behind the rise of serverless architectures, and provides an intro to the OpenWhisk open source project.
Presented at Cloud Native Day in Toronto, Canada on August 25, 2016.
Serverless architectures are one of the hottest trends in cloud computing this year, and for good reason. There are several technical capabilities and business factors coming together to make this approach compelling from both an application development and deployment cost perspective. The new OpenWhisk project provides an open source platform to enable these cloud-native, event-driven applications.
This talk will lay out the technical and business drivers behind the rise of serverless architectures, provide an introduction to the OpenWhisk open source project (and describe how it differs from other services like AWS Lambda), and give a demonstration showing how to start developing with this new cloud computing model using the OpenWhisk implementation available on IBM Bluemix.

Taking the Next Hot Mobile Game Live with Docker and IBM SoftLayerDaniel Krook
Presentation at the IBM InterConnect Conference in Las Vegas, Nevada on February 24, 2016.
Mobile games are the fastest-growing sector of the $70 billion video game industry, far outpacing traditional consoles. But companies that aspire to create the next hot title have to account for more than just the app downloaded to a user device. They must prepare for huge spikes in game play with scalable backends to handle massive data and transactions behind socially linked user profiles and global leaderboards. This talk looks at how IBM successfully partnered with Firemonkeys, a major studio that had hit their vertical scaling limit, to design and deploy a new Docker-based architecture on SoftLayer. This scale-out architecture is able to handle an order of magnitude more customers for their next major release.

Docker: containerizing a monolithic app into a microservice-based PaaS
Convert a monolithic application into a microservice-based PaaS using Docker and related, containerization technologies. This will be the third presentation of a series of presentations that began greater than one year ago to evangelize the benefits of Docker. The scope of content spans from a development environment to a hybrid PaaS, and how Containerization is an enabler of architectural choice, innovation, scalability, and polyglot solutions.
The basics of Docker will be examined including repositories, brief discussion about managing and monitoring Docker containers, service discovery, and security. New and emerging technologies will be a constant theme, particularly about microservices, in addition to the ongoing evolution of the market and what the future may bring. Common organizational issues (and tactical solutions) that may impede successful decomposition and migration of legacy monoliths will be discussed, including security, DevOps and refactoring.
Hypothetical architectures will be described for building progressively more robust and complex applications and deployment models. The goal is to highlight the power, flexibility and scalability that containers enable.
Examples will start simple, from a local development environment, that is a simple two container setup that encapsulate a database and application tier. Subsequent discussion will involve progressively more complex and robust deployments that include features such as service discovery, automatic load balancing, and abstractions to simplify linking of containers including service gateways. With the stopping point of a hybrid PaaS.

OpenWhisk is an open-source serverless platform ideally suited to a wide range of scenarios including cognitive, data, IoT, microservices, and mobile workloads. Since we presented OpenWhisk at ServerlessConf London a lot has happened. It has been successfully accepted as an Apache Incubator project and the first production OpenWhisk deployments have happened. From a technical point of view we have added capabilities like a better API Gateway integration and support for web actions, have added integrations with IBM App Connect, IBM Message Hub, and more. During this talk we will discuss our latest additions and illustrate how to benefit by “going” serverless with OpenWhisk by exploring some real-world customer usecases with a focus on how serverless architectures can be exploited in totally different scenarios. Using these usecases we will explain how OpenWhisk works and why it is the ideally platform for these emerging workloads. After the talk we will be looking forward to discussing your own usecases in more detail at our booth.

Ever been frustrated with a conference schedule app that freezes up when everyone opens it right after the first day’s keynotes? Ever played a mobile game that was so popular that its backend couldn’t keep up with real-time multiplayer interaction? If you’re an app developer, chances are that you’re looking for a better mobile backend architecture that can effectively match user demand at the exact moment it’s needed while taking advantage of new per-request cost models promised by serverless technologies.
The Apache OpenWhisk project (supported by IBM, Adobe, Red Hat, and others) provides a polyglot, autoscaling environment for deploying cloud-native applications driven by data, message, and REST API call events. Daniel Krook explains why serverless architectures are great for cloud workloads and when to consider OpenWhisk in particular for your next web, mobile, IoT, bot, or analytics project.

Does the concept of server-less architecture intrigue you? OpenWhisk (https://git.io/vKeu3) accelerates innovation through creative chaining of microservices into highly scalable applications. By abstracting away infrastructure, OpenWhisk frees small teams to rapidly work on independent pieces of code simultaneously, keeping development focused solely on creating essential business logic. OpenWhisk allows you to create rules to connect events with actions and compose microservices that get executed independently and in parallel.
With a bit of code, you can have OpenWhisk process events from your Swift Object Storage; similar to what you can do with Lambda functions and AWS S3 storage. As an example, we will demonstrate how you can create an OpenWhisk action to transform an image into a thumbnail whenever a new (larger) image is uploaded into a Swift Container.
How to build an event-driven, polyglot serverless microservices framework on ...Animesh Singh
Serverless cloud platforms are a major trend in 2016. Following on from Amazon’s Lambda service, released last year, this year has seen Google, IBM and Microsoft all launch their own solutions. Serverless microservices are executed on-demand, in milliseconds, rather than having to sit idle waiting. Users pay only for the raw computation time used.
In this talk detail how to build a distributed serverless, event-driven, microservices framework on OpenStack

Announcing Amazon Athena - Instantly Analyze Your Data in S3 Using SQLAmazon Web Services
Amazon Athena is a new serverless query service that makes it easy to analyze data in Amazon S3, using standard SQL. With Athena, there is no infrastructure to setup or manage, and you can start analyzing your data immediately. You don’t even need to load your data into Athena, it works directly with data stored in S3.
In this webinar, we will show you how easy it is to start querying your data stored in Amazon S3, with Amazon Athena. First we will use Athena to create the schema for data already in S3. Then, we will demonstrate how you can run interactive queries through the built-in query editor. We will provide best practices and use cases for Athena. Then, we will talk about supported queries, data formats, and strategies to save costs when querying data with Athena.
Learning Objectives:
• Learn about the capabilities and features of Amazon Athena
• Understand the different use cases
• Describe how to run queries and options to store and visualize results
• Understand integration with other AWS big data services such as Amazon QuickSight
Talk @ API Days Paris, 13/12/2016
Simplifying development and deployment of serverless applications with Open Source frameworks and tools: Serverless, Gordon, Chalice, etc.
Lambda is the next stage in the evolution of the AWS platform. It allows you to build reactive, event-driven systems that are easy to deploy, update and scale. Amazon manages all the undifferentiated heavy-lifting for you so you can focus on delivering value to your customers with even greater speed and cost efficiency.
Join Yan in this talk as we take a deep dive through AWS Lambda and the Serverless framework.
We'll see how to start building reactive systems using AWS Lambda, Kinesis and API Gateway, without having to manage any servers. And, you only pay for your services when they are used. We'll discuss lessons learned, best practices and current limitations with AWS Lambda.
We'll also get to know the Serverless framework, which helps automate both deployment and versioning so that you can better focus on the things that matter to your customers.

Being serverless and Swift... Is that allowed? Dev_Events
Animesh Singh, STSM - IBM Cloud Platform, @AnimeshSingh
Of course its allowed - just matters how you do it. In this part of the workshop we’ll start with
serverless: New cloud programming models enabled by serverless architectures are emerging, allowing
developers to focus more sharply on creating their applications and less on managing their
infrastructure. The OpenWhisk project started by IBM and now part of Apache provides an open source
platform to enable these cloud native, event-driven applications. In this talk, we will provide an
overview of serverless architectures, introduce the OpenWhisk programming model, and then show
how to deploy an OpenWhisk application on IBM Bluemix OpenWhisk.
Then we’ll get Swift! It’s not only a language you turn to to build your iOS application, but it can also be
the language you can use to build your backend. This part of the workshop will use a text-based
adventure game called "GameOn" as an example for building a Server-side Swift App.
Topics include:
• How to create a web service using the IBM Kitura web framework • How to integrate the Watson SDK
for Swift into your application • How to dockerize your Swift application and deploy it to Bluemix
For just over a year, Swift has been available as a formal release on Linux and frameworks like Kitura and Vapor have made it possible to build mobile backends and web applications on the server. Running Server Swift is however not your own option for becoming a fullstack engineer and building backends in Swift. Amazon, Microsoft, Google, IBM and others are all also providing the ability to run Serverless (aka Lambdas or Functions), with some of those supporting the use of Swift.
This session will introduce you to Serverless Swift, highlight how it compares to Server Swift and show you some applications that have been built with Server(less) Swift.
Quick introduction to Apache OpenWhisk, an open source, distributed Serverless platform that executes functions (fx) in response to events at any scale. OpenWhisk manages the infrastructure, servers and scaling using Docker containers so you can focus on building amazing and efficient applications.
With third party clients connecting to your service you may find that the assumptions or opinions of a typical rails application are not robust enough. We'll run through some key considerations when building an API that will be consumed by a mobile app.
Building event-driven (Micro)Services with Apache Kafka EcosystemGuido Schmutz
Should you use traditional REST APIs to bind services together? Or is it better to use a richer, more loosely-coupled protocol? This talk will dive into how we piece services together in event driven systems, how we use a distributed log (event hub) to create a central, persistent history of events and what benefits we achieve from doing so. Apache Kafka is a perfect match for building such an asynchronous, loosely-coupled event-driven backbone. Events trigger processing logic, which can be implemented in a more traditional as well as in a stream processing fashion. The talk will show the difference between a request-driven and event-driven communication and show when to use which. It highlights how the modern stream processing systems can be used to hold state both internally as well as in a database and how this state can be used to further increase independence of other services, the primary goal of a Microservices architecture.
Today’s cutting edge companies have software release cycles measured in days instead of months. This agility is enabled by the DevOps practice of continuous delivery, which automates building, testing, and deploying all code changes. This automation helps you catch bugs sooner and accelerates developer productivity. In this session, we’ll share best practices (including ones followed internally at Amazon) and how you can bring them to your company by using open source and AWS services.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
