Intel Expressway API Manager and The Rise of Mobile Middleware

I just returned from an exhilarating trip to the Gartner AADI show in Las Vegas last week. There are a lot of exciting things happening at Intel in the Data-center Software Division (DSD), especially with respect to the Expressway Product Line.

First, we had our first live demo of the integrated solution that showcases Intel(R) Expressway API Manager and the Mashery API Management Portal. This is a true best of breed match between what we think is one of the best security gateways in the market and the de-facto market leader in API management, bringing the best possible product set to our end customers.

Second, we did multiple workshops with Gartner visionary Appcelerator. They make a slick cross-platform mobile development environment that produces native code for mobile applications, and the cool part is that the developer only has to write their code in JavaScript. So you can think of their tool as a cross-compiler that churns out native code optimized for Android, iOS, Blackberry and Windows devices but  only requires the developer to have a working knowledge of JavaScript.

The combination of Appcelerator Titanium and Intel(R) Expressway API Manager is a killer best of breed architecture for jumpstarting an Enterprise ready native mobile application. In fact, we showed a live proof of concept that went from a non RESTful back-end to a native application running on an iPhone with Enterprise grade data level security controls in 15 minutes.

Enterprises and Native Mobile Applications

Let’s walk through the scenario. Suppose you are a large Enterprise and you want to get a mobile project going at your enterprise. Furthermore, you don’t really want to compromise with HTML5 – native applications typically provide the best performance and device integration. Here are some of the hurdles – first you will likely have fragmentation in your data-center. You probably have:

  • Disparate middleware and database technologies
  • Disparate identity management silos
  • Disparate programming languages, with different levels of expertise
  • Current architecture optimized for web browsers, e.g. n-tier designed for a thin/dumb client
  • Vertical integration prohibits cloud outsourcing
  • Inconsistent security model across domains

And now, on top of these challenges you want:

  • BYOD with enterprise native mobile applications
  • Low development costs
  • Fast time to market
  • Robust security for Enterprise data

API Enabling Your Existing Architecture

Mobile applications have tremendous value for a mobile sales force. The example we took was a sales manager who is on the road and wishes to access enterprise data securely, directly from the mobile device. We took two examples of data – localized revenue information and the protection of personally identifiable information. In the first example this is a revenue report of local retail stores, which might be accessed by a manager on the road using the location of the tablet or smartphone.

In the second example we can take that same manager and assume he is hiring new employees and has to enter sensitive personally identifiable information (PII) such as a social security number, name, address, date of birth or maybe a driver’s license number.

Here is what the architecture looks like:

 

 

 

On the right hand side we have the Enterprise and the existing architecture. In this example we assumed the Enterprise has a RESTful service for handling new hire information and a SOAP web service for querying revenue information. Further, we assumed the Enterprise currently uses Active Directory for its identities.

Using the Intel(R) Expressway API Manager as a mobile middleware we can put a RESTful facade in front of these disparate systems and expose two simple endpoints for the mobile device. Further, the gateway performs important functions, including:

  • The termination and acceleration of SSL (remember, with mobile, you may easily scale to hundreds of thousands of individual “apps”, all hitting the back-end infrastrcture)
  • Perimeter security for content based threats, such as SQL injection
  • Delegated authentication to the Enterprise LDAP based on an API key in the request
  • Throttling of requests, including denial of service protection (remember, again, with mobile devices there could be thousands)
  • Optimization of content sent back to the device. In our example we showed the transformation of XML to JSON, which is optimized for the mobile phone
  • Data protection, including format preserving encryption, a special mode of AES that prefers the length and character set of data-types. This is especially useful for handling the new hire information, such as the social security number
  • Routing and composition of data accessed form multiple databases. Mobile applications may need to aggregate data from multiple databases, combine it into a single response before it is sent to the mobile device

The best part about the Intel(R) Expressway API Manager is that this entire flow can all be designed in Eclipse using drag-and-drop actions. No coding is required. If you are looking for a quick way to jump-start a native mobile application at your enterprise with minimal back-end changes, give us a shout. We may be able to help!

IBM’s campaigns focus on vendors in the technology marketplace, the future of testing, Big Data and analytics, and mobile platforms.
For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...
Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...
Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...

Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...
