Developing for Hybrid Cloud with Bluemix
This document discusses two ways to integrate an IBM i program with a Bluemix application using REST services. The first way uses WebSphere Application Server Liberty Profile to expose a REST service that calls the IBM i program. The second way uses Cast Iron Live to expose an API that calls a REST service behind the firewall, which is then consumed by a Cloud Integration Service in Bluemix. Both options allow developers to integrate existing IBM i assets with new applications in Bluemix.

Apps are everywhere The quantity and usefulness of web and mobile apps has led to an “app revolution” among consumers and businesses alike.

- 8. USE CASE DESCRIPTION The use case demonstrates how to access an IBM i program from a web app. The original program is an RPG program that allows to get the reseller list using the area code. We have implemented two different use cases, in order to show how to integrate Bluemix Web App with an RPG program behind the firewall: 1.In the first case, using the WebSphere Application Server Liberty Profile, we have exposed a REST service which calls, via IBM i Toolbox library, the RPG program running on V7R1. The front-end application is on Bluemix, using “Liberty for Java and it consumes the REST service exposed via Internet. 2.In the second case, using Cast Iron Live we have exposed an API that calls a REST service behind the firewall, through the Cast Iron Secure Connector. The Cloud Integration Service on Bluemix, consumes the REST service, leveraging Cast Iron Live. The front-end application is on Bluemix using “Node.js”.

Editor's Notes
- #2 Please note: Presenter notes are on every slide. Written as a suggested script to help with messaging.
- #3 Apps Are Everywhere Over the last 5 or so years, we’ve experienced an “App Revolution” on the web, on our smartphones, in our cars, on wearable devices (like a NikeFuel band, Smart Watch, Google Glass), and in our homes. Apps today allow interactions that we wouldn't have imagined 5 years ago. Architects can design homes on their iPads, merchants can swipe credit cards and accept payments anywhere with their phones, and runners can track their progress with a band on their wrist. Even my mother knows the phrase “there’s an app for that.” Experience Matters All of the associated data (like a runner’s average speed and location over the course of a 30 minute run) is often times pushed up to the cloud (as it’s being generated) for further processing, storage, or to allow syncs other devices and services. Customers expect an integrated experience on the web, across all of their devices, in physical stores, and even talking with customer service on the phone. Cloud Makes it Possible Needless to say, the cloud has been a very large driving factor in the “App Revolution.” It provides a fast, simple, and cost effective way to for startups and enterprises alike to deploy and host applications and mobile backends over the internet. Apps can be stitched together quickly with pre-built assets exposed as APIs - cloud has made this possible. Simply put, cloud keeps all of us connected.
- #4 The instant power and speed of cloud has brought about new expectations for building applications on it. Developers now expect: To be able to deploy updates to their applications in seconds To write their code in whichever tool or language they choose Each has its own distinct “personality” and followings of developers have evolved around each of these To be able to continually integrate working copies of code into a shared mainline at multiple points during the day To focus on writing code, not on the administration of servers, virtualization, operating systems, and middleware. To “fail fast” - or ensure applications fail immediately and visibly to speed debugging and fixes To integrate useful APIs into their applications - who wants to write code that’s already been written and tested? To build applications that are mobile ready - as users today expect their experience to be tailored to whatever device they happen to be using.
- #5 Timing is critical if your apps (and the functionality they provide to your employees and/or customers) are to keep up with the new expectations and competition the app revolution has generated. Let’s see how everything stacks up: Core IT represents everything you own and manage in your data centers (the full stack pictured here). This is still a critical part of enterprise IT - let’s take a look why it is beneficial and what it takes to manage all of this. Core IT Benefits As stable and customizable as the customer wants - the only main limitation is cost. Necessary for certain solutions (Core IT still has value in many scenarios i.e. transaction processing) Houses a lot of the investments most companies have already made (customer data, inventory, SAP, you name it). Core IT Time Commitment Typically takes weeks to setup an environment and deploy an initial app - customer manages entire stack pictured here Have to maintain hardware and software as well (think environment uptime, fixes, upgrades). Dedicated staff necessary. Thus, Core IT doesn’t lend itself to the experimental nature of development in the cloud/app revolution
- #6 Infrastructure as a Service (and specifically IBM’s acquisition of SoftLayer) was the cloud’s initial answer to the need for faster deployments, faster environment setup, etc… by abstracting the infrastructure from the customer. IaaS Benefits Networking, Storage, Server, Vitualization managed by service provider. Most customizable cloud offering Solutions where` customizability of OS, Middleware, or Runtime needed IaaS Time Commitment Customer sets up and manages OS, Middleware, and Runtime - these still take at least a matter of days to setup and reach an initial deployment Maintenance/upgrades necessary as well
- #7 We’ve realized that, in a large number of use cases, our customers want to move even faster and don’t need to spend the time managing the platform (VM, OS, Middleware, Runtime). IBM’s answer: Bluemix (platform as a service). PaaS Benefits Setup your environment and deploy apps quicker than any other offering Service provider manages the Infrastructure AND the platform PaaS Time Commitment Minutes to initial deployment - developer can handle everything on his/her own Maintenance and upgrades of Platform and Infrastructure handled by service provider
- #8 While timing is critical (what we just discussed), the systems and data you use today can’t be forgotten. That’s why Bluemix simply and securely connects to core IT and even other clouds (leveraging IBM’s proven reputation as a systems integrator). Hybrid cloud, where Public and Private clouds work together with Core IT investments, is critical to success given the app revolution and the expectations and increased competition it has generated. Overall, hybrid cloud represents the “New IT…”

Collaborative development and continuous testing support the evolution of a business idea into a high quality software solution by applying lean principles, facilitating collaboration among all stakeholders, and striking the optimal balance between quality and time to market. By establishing a solid development and testing strategy, organizations can remove unnecessary project risk, reduce costs and ensure their teams stay productive.
