When Sybase first released the Unwired Platform in 2008, it was intended to be a complete end-to-end development environment for mobile applications. SUP developers would create the middle tier components (a.k.a. Mobile Business Objects), and the client application executables from a single, integrated Eclipse-based toolset. There was a "PowerBuilder-like" 4GL screen painter, called the Device Application Designer (or DAD), that compiled down to native Blackberry 5/6 or Windows Mobile 6.5 applications. (Yes, it's hard to imagine, but there was a time when iOS devices were not allowed to play in the Enterprise Mobile Application playground...)
Several market forces emerged around that time and started to cast doubts on the wisdom of the "complete end-to-end" strategy. Those were (in no particular order or importance):
- The release of the iPad, and overall growth of iOS in the enterprise mobile space;
- The subsequent struggles of RIM and Blackberry to maintain their place in a market they had been dominating;
- The fact that there were hundreds of thousands of developers already proficient in languages like C#, Java, and Objective-C;
- The emergence of OData as the primary protocol for data exchange over the web and HTTP;
- The rise of HTML5 as a cross-platform alternative to native mobile application development;
- The introduction of the Google Android platform, and it's ascendence in the mobile marketplace;
- The acquisition of Sybase by SAP, which infused the product with fresh new ideas (and a lot more development resources...)
It became fairly evident that the DAD was very dependent upon market trends and an ever-expanding variety of mobile platforms that were outside SAP's control, and was not the best long-term direction for UI tooling. As a result, the DAD got sent straight to the bit bucket with the release of SUP 2.0. The direction then became one of "openness", and embracing alternative development platforms and open industry standards.
This blog post will cover the four major API's that have been released into SMP since then. We'll cover how to generate them, what their characteristics are, when to use them (and when not to). The API's we'll cover here are:
- The Hybrid App API
- The Native Object API
- The OData SDK
- The HTTP REST API
Note: There is a 4GL programming tool for HTML5 development in SUP/SMP, called the Hybrid App Designer. I'm not discussing that tool here, because it's integrated with the platform and doesn't require the specific generation of the API libraries. And developers are hard at work crafting a new HTML5/UI5 programming tool for SMP 3.0 that will deploy hybrid apps into the Kapsel container. This tool will be called AppBuilder.
Hybrid App API
To generate the Hybrid App API from an MBO diagram, right-click the top level folder in the Workspace Navigator, and select "Generate Hybrid App API...". Figure 1 below shows where this option is located.
This opens a wizard which has two panels. The first prompts for the MBOs to include in the generation, and the second allows you to construct the message template for any Server-initiated start point.
Native Object API
The Object API can be thought of as the "native" equivalent to the Hybrid App API, in that it exposes the MBO object model to the client UI developer, but there are two major differences:
- The Native Object API is generated into the native language of the targeted mobile platform. This list includes Objective-C and Xcode for the iOS platform, Java for both the Android and Blackberry platforms, and C# for the Windows/Windows Mobile platform. The app developer is responsible for crafting the user interface and business logic layers in the native IDE for that platform. If you plan on developing multiple versions of a mobile app, one for each popular mobile platform, then it is required to generate the Object API, and develop a separate UI/logic layer, for each of those targeted platforms.
- The Native Object API also enables full offline access to the mobile application data, because it uses Replication-based Sync (RBS) when communicating with the SMP server.
To generate the Object API for a specific language and platform, right-click the Mobile Business Objects folder in the Workspace Explorer, and select "Generate Code...". This opens a wizard with three panels. The first prompts for a saved configuration profile (if there is one). The second prompts for the MBOs to include in the generated code. The final panel is the important one, and is shown below.
We call it DevOps but much of the time there’s a lot more discussion about the needs and concerns of developers than there is about other groups. There’s a focus on improved and less isolated developer workflows. There are many discussions around collaboration, continuous integration and delivery, issue tracking, source code control, code review, IDEs, and xPaaS – and all the tools that enable those things. Changes in developer practices may come up – such as developers taking ownership of code ...

The rise of containers and microservices has skyrocketed the rate at which new applications are moved into production environments today. While developers have been deploying containers to speed up the development processes for some time, there still remain challenges with running microservices efficiently. Most existing IT monitoring tools don’t actually maintain visibility into the containers that make up microservices. As those container applications move into production, some IT operations t...

For organizations that have amassed large sums of software complexity, taking a microservices approach is the first step toward DevOps and continuous improvement / development. Integrating system-level analysis with microservices makes it easier to change and add functionality to applications at any time without the increase of risk. Before you start big transformation projects or a cloud migration, make sure these changes won’t take down your entire organization.

Containers have changed the mind of IT in DevOps. They enable developers to work with dev, test, stage and production environments identically. Containers provide the right abstraction for microservices and many cloud platforms have integrated them into deployment pipelines. DevOps and containers together help companies achieve their business goals faster and more effectively. In his session at DevOps Summit, Ruslan Synytsky, CEO and Co-founder of Jelastic, reviewed the current landscape of Dev...

DevOps is often described as a combination of technology and culture. Without both, DevOps isn't complete. However, applying the culture to outdated technology is a recipe for disaster; as response times grow and connections between teams are delayed by technology, the culture will die. A Nutanix Enterprise Cloud has many benefits that provide the needed base for a true DevOps paradigm. In his general session at 20th Cloud Expo, Chris Brown, a Solutions Marketing Manager at Nutanix, will explore...

DevOps and microservices are permeating software engineering teams broadly, whether these teams are in pure software shops but happen to run a business, such Uber and Airbnb, or in companies that rely heavily on software to run more traditional business, such as financial firms or high-end manufacturers. Microservices and DevOps have created software development and therefore business speed and agility benefits, but they have also created problems; specifically, they have created software securi...

All clouds are not equal. To succeed in a DevOps context, organizations should plan to develop/deploy apps across a choice of on-premise and public clouds simultaneously depending on the business needs. This is where the concept of the Lean Cloud comes in - resting on the idea that you often need to relocate your app modules over their life cycles for both innovation and operational efficiency in the cloud. In his session at @DevOpsSummit at19th Cloud Expo, Valentin (Val) Bercovici, CTO of Soli...

Thanks to Docker and the DevOps revolution, microservices have emerged as the new way to build and deploy applications — and there are plenty of great reasons to embrace the microservices trend. If you are going to adopt microservices, you also have to understand that microservice architectures have many moving parts. When it comes to incident management, this presents an important difference between microservices and monolithic architectures. More moving parts mean more complexity to monitor an...
