Microservices are a new architectural approach to modularize systems into smaller units. The benefits include that services can be adapted more rapidly to changing business demands. Application programming interfaces (APIs) are crucial in every microservice architecture (MSA) as they link up the various microservices. Key challenges of MSA are getting API security, access control and analytics right in an environment that is constantly changing. This workshop talk will show how the features of the 3scale API management platforms in combination with the Red Hat OpenShift PaaS can be leveraged to overcome these challenges.

London Adapt or Die: Kubernetes, Containers and Cloud - The MoD Story

Apigee | Google Cloud

Context-aware apps - apps that know who you are, where you are, and what you've done - have been all the rage the last few years. Facebook's news feeds, Google Now, and Amazon Recommendations are examples of context-aware applications. Over the last few years, advancements in machine learning, big data, NoSQL, and API technologies has drastically reduced the complexity of building such apps, but requires a brand new approach system architecture. This presentation covers: Lambda architecture and Microservices - two new architectural styles to build contextual apps at scale How companies like Twitter and Netflix have implemented lambda architecture and microservices for recommendations, targeting, and more How Apigee uses both new architectures to implement predictive analytics through Insights (our big data predictive analytics product)

3scale

Keynote at APIDays Melbourne 2016, Steven Willmott - 3scale. Organizations have recognized that making available IT systems as APIs for both internal and external developers can create huge new opportunities for agility, products and ultimately revenue. However, while this "platform thinking" holds great potential, it can be extremely challenging to determine how to deliver on these opportunities. In this talk we'll look at how focusing on the value APIs can deliver helps underpin genuine success for an API program and an organization's platform initiatives as a whole.

Andreas Nauerz and Michael Behrendt - Event Driven and Serverless Programming...

ServerlessConf

More than one year ago our team has, as a joint effort between research and development, started investigating the field of event-driven & serverless computing to propagate a model relieving users from the need to worry about complex infrastructural & operational aspects in order to allow them to focus on quickly developing value-adding code, especially by radically simplifying developing microservice-oriented solutions that decompose complex applications into small and independent modules that can be easily exchanged. Serverless computing does not refer to a specific technology. Nevertheless some promising solutions, such as OpenWhisk, have recently emerged. Hence, OpenWhisk is one player in this new field. It is a cloud-first distributed event-based programming service and represents an event-action platform that allows you to execute code in response to an event. It provides you with the previously mentioned serverless deployment and operations model, with a fair pricing model at any scale that provides you with exactly the resources – not more not less – you need and only charges you for code really running. It offers a flexible programming model. incl. support for languages like NodeJS and Swift and even for the execution of custom logic via docker containers. This allows small agile teams to reuse existing skills and to develop in a fit-for-purpose fashion. It also provides you with tools to declaratively chain together the building blocks you have developed. It is open and can run anywhere to avoid and kind of vendor lock-in. During this presentation, Michael Behrendt and Andreas Nauerz will talk about their journey through the world of serverless computing, the core concepts, the key value proposition and differentiators, typical usage scenarios, and the underlying programming model of serverless computing in general and OpenWhisk in particular and conclude their session with some basic demos.

Intuitive APIs and Developer Education

Postman

API standards, from SOAP to REST to GraphQL, have evolved to meet the needs of API providers and developer consumers. They make APIs "intuitive" by making them predictable. When product designs bump up against the constraints of standards, you can choose to force a fit or, you can break from convention and invest in educating developers about your choices. Through case studies (including Facebook's Open Graph and Slack's workspace apps project), we'll examine the tradeoffs, consequences, and some learnings about how to get your developer community to come along with you.

Application Insights for Integration Developers

Sriram Hariharan

How well does your solution work?, How do you know how well your solution works? In this session, Mike will show you how developers of integration solutions can use Azure Application Insights to complement existing monitoring solutions to provide developers with an additional level of insight into the way their solutions behave in the real world and how this can be applied to the types of integration components which we normally build.

API Design first with Swagger

Tony Tam

Presented at JavaOne 2016. Using Swagger has become the most popular way to describe REST APIs across the web, enabling people to more quickly understand and communicate with services, with developer-friendly documentation and rich, autogenerated client SDKs. As the API has moved more into being one of the most important aspects of a service, the Swagger definition has become increasingly more important and essential to the design phase. This presentation explains how the Swagger definition can be used to streamline the iteration process and enable client and server engineers to develop concurrently with complex APIs.

RapidValue

The concept of serverless architecture may not be very new but lately, it has been observed to be an emerging trend in the cloud. The reason behind this is the simple fact that it has simplified life for developers by providing them with ample time to code instead of using it to set up servers. The servers are set up by the cloud service providers and this eliminates the need for managing anything else except for the environment in which it has to execute. The benefits of employing serverless architecture are being talked about and businesses are on an endeavor to leverage the function’s code that has to be uploaded along with it configuring it for maximum output.

Ludovic Piot

Tout comme le Cloud IaaS avant lui, le serverless promet de faciliter le succès de vos projets en accélérant le Time to Market et en fluidifiant les relations entre Devs et Ops. Mais sa mise en œuvre au sein d’une entreprise reste complexe et coûteuse. Après 2 ans à mettre en place des plateformes managées de ce type, nous partagons nos expériences de ce qu’il faut faire pour mettre en œuvre du serverless en entreprise, en évitant les douleurs et en limitant les contraintes au maximum. Tout d’abord l’architecture technique, avec 2 implémentations très différentes : Kubernetes et Helm d’un côté, Clever Cloud on-premise de l’autre. Ensuite, la mise en place et l’utilisation d’OpenFaaS. Comment tester et versionner du Function as a Service. Mais aussi les problématiques de blue/green deployment, de rolling update, d’A/B testing. Comment diagnostiquer rapidement les dépendances et les communications entre services. Enfin, en abordant les sujets chers à la production : * vulnerability management et patch management, * hétérogénéïté du parc, * monitoring et alerting, * gestion des stacks obsolètes, etc.
