Kubernetes Event-driven Autoscaling (KEDA) provides application autoscaling on Kubernetes using a variety of metric sources. It automatically scales deployments, jobs, and other resources. KEDA supports over 30 built-in scalers for sources like Azure, AWS, Google Cloud, and more. It is cloud-agnostic and focuses on scaling applications without managing the scaling internals. The Azure Functions CLI makes it easy to deploy functions to Kubernetes and automatically configure KEDA for autoscaling. KEDA is an open source project with over 2,800 stars on GitHub and contributions from Microsoft, Red Hat, and other companies.

Building a multi-tenant PaaS is not a walk in the part, certainly if the platform you are building on is constantly changing.
In this session I'll walk you through the adventure we've been on where you'll learn about the challenges we've had and how we approached them and whether or not our decisions worked out or not.
– How to design for scale
– How to operate the platform
– How to grow a platform mindset and force ownership
– How to run tests for your whole platform
– How to design for multi-tenancy
– How to approach constant change

In this interactive presentation by Hugh McKee, Developer Advocate at Lightbend, we’ll share our experiences helping our clients create a system architecture that can support high throughput microservices (aka "Megaservices"). We’ll do that using IoT demo applications designed to push cloud service providers like Amazon and Google to their limits. Using sample code that you can later run on your own machine, we’ll look at:
* Modeling real-life digital twins for hundreds of thousands of IoT devices in the field, looking into how these megaservices are implemented in Akka.
* Visualizing Akka Actors–which represent IoT digital twins–in a “crop circle” formation that represents a complete distributed Reactive application, and watching at messages are processed across Akka Cluster nodes using cluster sharding.
* Some code behind the whole set up, which is built using OSS like Akka, Java, JavaScript, and Kubernetes.

KubeCon China 2019 - Building Apps with Containers, Functions and Managed Ser...Patrick Chanezon
Cloud native applications are composed of many technologies and components, but three canonical abstraction emerged in the past few years that help developers structure their architecture: container, functions responding to events, and managed services.
This talk will explain how to develop (Docker, local Kubernetes, virtual Kubelet, OpenFaaS), deploy (managed Kubernetes, functions and services) and package (CNAB specification and tooling) applications using these three components and look at not only deployment workflows but also at day 2 concerns that a developer would need to consider in the cloud native landscape.
We will demo every topic and a Github repository will be available for developers to reproduce the demos and learn at their own pace.

Dutch Oracle Architects Platform - Reviewing Oracle OpenWorld 2017 and New Tr...Lucas Jellema
Not since the rise of Service Oriented Architecture (and the supporting Fusion Middleware technology) over a decade ago have we seen so much rapid change in terms of application and infrastructure architecture. Cloud, Microservices and DevOps are perhaps the most explicit examples – but many other developments in technology, architecture and even the industry at large have an impact on how enterprises consider and employ IT – such as machine learning, IoT, blockchain.
In this session for (infrastructure, solution, application, enterprise, security, data) architects – we will present the main stories, roadmaps and technologies from Oracle OpenWorld 2017 (and JavaOne) that influence, shape and enable architecture. We will brainstorm together on the consequences of the new directions outlined by Oracle – and coming our way from other quarters. We are seeing a a lot of change. New opportunities arise – that may become challenges or threats if we fail to recognize and embrace the change in time. This session will help us all to get a better handle on the winds in enterprise IT in general and in Oracle land in particular.
Among the topics we will present and discuss are:
- The Only Way is Up – the inevitable and imminent move from on premises to the cloud, and upwards in the stack – from IaaS to SaaS
- Security and Ops in a hybrid landscape (multiple clouds & on premises, multiple technologies & interaction channels)
- Autonomous Database – what, when, how
- Oracle’s cloud strategy, High PaaS and Low PaaS, Open [source] technology (star of the show: Apache Kafka) and the commodization of the traditional Oracle platform
- Container and Cloud Native at Oracle Cloud (Docker, Kubernetes Container Platform, Wercker, Istio Service Mesh, CNCF)
- Serverless
- Java Reborn – for microservices and cloud, modularized (highlights from the JavaOne conference)
- Disruptive: Blockchain, IoT, Machine Learning

ITProceed 2015 - Securing Sensitive Data with Azure Key VaultTom Kerkhove
Security has become more and more important as we move to the cloud and countries & companies are being hacked – remember the Sony hack? But how do we securely store sensitive data such as connection strings to our databases? Where do we store our encryption keys? Can I share them with my customers? How do I prevent abuse of my secrets and block them from doing so?
That’s what this session is all about – I will introduce you to the concepts of Microsoft Azure Key Vault where you can use this as it allows you to securely store keys, credentials and other secrets in the cloud. We will also have a look at how it enables us to store encryption keys for SQL Server TDE and how it can help you safeguard your cloud solutions even more.
Securing sensitive data with Azure Key VaultTom Kerkhove
As a developer you often have to use & store a lot of sensitive data going from service credentials to connection strings or even encryption keys. But how do I store these in a secure way? How do I know who has access to them and how do I prevent people from copying them and abusing them? On the other hand, SaaS customers have no clue how you store their sensitive data and how they use it. How can they monitor that? How can they revoke your access easily?
