With the onslaught of mobile devices and platforms from multiple vendors, the current technology underpinnings of mobility solutions are in a state of flux. With the hype surrounding the hardware and software offerings across the mobility solutions, it's a challenge for enterprises to differentiate between the offerings and also to plan for enterprise mobility strategies.
Across the solutions, however, there are four distinct patterns that have emerged, which are fundamental to the underlying architecture of various mobility solutions. Each of these patterns solves a broad use case and has their own advantages and disadvantages.
Understanding these patterns enables enterprises to evaluate multiple solution offerings, compare the pros and cons and also determine a mix of technologies that they can adopt for strategic mobile offerings.
This article presents multiple broad patterns that emerge from the various offerings currently in the market and compares and contrasts the advantages they offer and areas in which they lack.
Web 2.0-Based Applications
These applications are deployed on the server side, like the traditional JEE and .NET applications, except that the delivery channel is a mobile with limited screen space. Such applications need to take care of different resolutions of various mobile clients, but are otherwise "independent" of the final mobile device. The challenge here is to fit the content on the various screen sizes and allow for a reflow of elements should the size be different from the planned resolution.
The downside to a web application is that they would not be able to utilize the platform-specific features like accelerometer or interaction with a camera and other advanced hardware of the underlying hardware. This limitation is partially removed if HTML5 is used for mobile application development.
Native applications are separately installed on the mobile device. They are specifically created using the SDK of the target platform. Various examples are:
- iPhone: This uses iPhone OS SDK
- Android: Spawned by Google, this is a Java library to develop widget and applications for android phones
- BlackBerry SDK: This is used to create applications for BlackBerry
- Samsung Bada, Nokia/Intel Maemo are other OSes that are in the market
Native applications provide the maximum performance for an application, but have to be created individually for different platforms.
Web Standards-Based Native Applications
These applications provide performance, which is midway between the web and native applications.
These applications are developed using technologies such as Java or Flash. The code is compiled into byte code that runs in its own virtual machine. For example, the Java code runs in a Java Virtual Machine, while the Flash Code runs in an ActionScript Virtual Machine.
These virtual machines are created for all platforms, making the applications truly cross platform.
There are challenges in this approach due to conflicting commercial interests. Apple, for example, has banned Flash applications to be run on its platform.
These applications would need the appropriate underlying hardware to run the respective virtual machines.
Enterprises must decide the appropriate pattern for mobile application development as part of a strategic alliance with any mobile partner. This should also be aligned with the long-term vision of the enterprise and the underlying mobile platforms it needs to support.
The Open Compute Project is a collective effort by Facebook and a number of players in the datacenter industry to bring lessons learned from the social media giant's giant IT deployment to the rest of the world. Datacenters account for 3% of global electricity consumption – about the same as all of Switzerland or the Czech Republic -- according to people I met at the recent Open Compute Summit in San Jose. With increasing mobility at the edge of the cloud and vast new dataflows being pre...

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 ...

In the midst of the widespread popularity and adoption of cloud computing, it seems like everything is being offered “as a Service” these days: Infrastructure? Check. Platform? You bet. Software? Absolutely. Toaster? It’s only a matter of time. With service providers positioning vastly differing offerings under a generic “cloud” umbrella, it’s all too easy to get confused about what’s actually being offered. In his session at 16th Cloud Expo, Kevin Hazard, Director of Digital Content for SoftL...

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...

Our guest on the podcast this week is Jason Bloomberg, President at Intellyx. When we build services we want them to be lightweight, stateless and scalable while doing one thing really well. In today's cloud world, we're revisiting what to takes to make a good service in the first place. Listen in to learn why following "the book" doesn't necessarily mean that you're solving key business problems.

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...
