IBM WebSphere Developer Technical Journal

Issue 18.1: January 28, 2015


In this issue

It's 2015 and the importance - and challenges - of connecting things together have never been greater. And that's the theme of this issue of the IBM WebSphere Developer Technical Journal, in which we feature tutorials that will help you connect widely-used mobile apps with backend systems, connect the Internet of Things to a variety of devices relaibly, and connect your IBM PureApplication System to the data center network using the most ideal approach. Continuing with our Faster forward video series, a new demo illustrates the steps involved in exposing your APIs to the public using IBM API Management, and how to use the product's built-in analytics to learn how your APIs are being used.

    How to coordinate and execute an active-active topology with IBM MobileFirst Platform Foundation

    by Emmanuel Tissandier and Stéphane Lizeray
    Deploying a mobile application is more than just building a mobile application and deploying it to the public app store. In all liklihood, a mobile application talks to a backend system. And if the application is to be used in many places around the world by a large community, it is likely that the backend servers will be located in several data centers to more efficiently serve the requests from the mobile application. In an active-active topology, the server is installed in several data centers that all serve requests from mobile applications. Such a topology requires that you establish a database replication between the data centers. This tutorial explains how you can setup an active-active topology for the IBM® MobileFirst™ (formerly Worklight) Server, including setting up replication, to improve availability and performance, and achieve distributed workloads across sites.

    MQTT and IBM MessageSight: Secure, reliable communications for the next generation of resilient mobile applications

    by Nick Maynard
    Enterprise mobile applications are expected to run in a wide variety of situations, and must consider the capabilities of their target platforms. When communicating with backend services, they need to accommodate information confidentiality and integrity, unstable network connections, multiple client platforms, and more. MQTT is a publish-subscribe based lightweight message protocol. A critical enabler of the Internet of Things (IoT), MQTT can also be used for reliable enterprise messaging to mobile devices, enabling secure, reliable communications for the next generation of resilient mobile applications. This tutorial explores the requirements of such a use case, showing how MQTT and IBM MessageSight are uniquely placed to fulfill them.

    Network design for IBM PureApplication System, Part 1: Connecting the system to the data center network

    by Bobby Woolf and Santiago Ortega
    Although largely self-contained, you still need to connect IBM PureApplication® System to your data center network so that your external users can connect to, manage, and deploy workloads onto the system, as well as connect to those workloads and use applications running in the cloud. This three-part series of tutorials explains how the PureApplication System should be connected to the network, how its workloads can connect to the network, and alternative approaches to address network connection variations. This first installment presents an "ideal approach" network design, based on best practices, for how to cable the network switches in the system to ones in the data center and how to configure both sets of switches.

    Network design for IBM PureApplication System, Part 2: How workloads connect to the network

    by Bobby Woolf and Santiago Ortega
    In Part 2, you will see how workloads are connected to the data center network, enabling network clients to access the workloads.

    Network design for IBM PureApplication System, Part 3: Alternative approaches for connecting to the data center network

    by Santiago Ortega and Bobby Woolf
    This final tutorial considers variations to the "ideal" network connection design presented in Part 1, and shows how you can modify that design to handle them.

    IBM API Management end-to-end, Part 3: Exposing APIs to the public (with and without restrictions)

    by Soloman Barghouthi
    Although not a new concept, APIs are part of a culture shift that involves mobile applications and cloud computing. IBM API Management is a software product that exists for the purpose of API exposure and discovery, to aid in the creation, export, import, and management of APIs and their lifecycle. This four-part series of videos on IBM API Management together make up an end-to-end demonstration of the product that includes creating a restful API, testing it, publishing it in IBM API Management, and finally using the published API from a mobile application. This third installment used the RESTful API created in Part 2 and demonstrates how you can expose it to the public in ways that let you control access to it, and how you can leverage built-in analytics to see how your APIs are being used.
