Reason # 18: Distributed Application Architecture

20 Reasons to Migrate Magic eDeveloper, uniPaaS and Magic xpa to .NET by Upgrading Rather than Converting

Magic xpa Application Platform utilizes a Distributed Application Architecture that offers a high level of choice between different computing environments. The interoperable nature of Distributed Application Architecture also means that Magic xpa applications have the ability to operate in multi-database, multi-platform, and multi-network data processing contexts. Using the simple interface common to all Magic xpa applications, every user, from any workstation, can access any type of local or remote database, execute queries, and update the data. As we shall see, Magic xpa Application Platform provides capabilities for distributed architecture, application partitioning, MDI, and secure communications out-of-the-box. When converting Magic eDeveloper, uniPaaS or Magic xpa to C#.NET, these advantages are lost.

In an environment where multiple computers are connected by a Local Area Network (LAN) or Wide Area Network (WAN), Magic xpa’s distributed application architectures automatically utilize a specific form of distributed processing.


Fortunately, when you install Magic xpa, you don't have to know how the distributed application architecture is set up, however you can adjust the settings if desired. The diagram below illustrates what is happening behind the scenes in Magic xpa's distributed application architecture.

The process begins when a client, such as a browser or Rich Client application, makes a request to the enterprise server. It does this via a requester, usually a Web server. Each client has its own requester.

The requester uses the broker to communicate with the Magic xpa enterprise servers. This is a Magic xpa Runtime engine (MgxpaRuntime.exe) functioning as an enterprise server. The broker scans its list of prioritized servers to find a server that is not busy and informs the requester which engine is available. If all the engines are busy, the event is added to the broker's request queue.

Once an engine has finished handling a request, the Runtime engine sends the request results directly to the client and notifies the broker that it is available to process the next client request. A check is made if there are pending requests in the queue which are for the same application as the one loaded in the Magic xpa engine. If there are pending requests, the broker extracts the requests with a higher priority and sends it to the engine.

The term application partitioning is used to describe the process of developing Magic xpa applications that distribute the application logic among two or more computers in a network. In the simplest case, the application can run on a single PC, as a remote service, and send task requests for execution to a server. In more advanced cases, the application logic can be distributed among several servers.
The first step in creating a partitioned application is choosing which components of the application run on the server system or systems. The criteria for making the choice are the components that would most benefit in performance and maintainability, if they were to run on the server. Note that the decision whether a program or task runs in the Requester Client or in the system need not necessarily be made when the application is designed, but the design must take this into consideration as only background-mode tasks are applicants for partitioning.

In Magic xpa, background enterprise servers and Online programs are multi-threaded. This gives you the ability to have parallel task execution in your projects.

Each thread accesses a different Runtime context, and does not interact with other threads. To work with multiple threads in Online programs, Magic xpa provides you with Multiple Document Interface (MDI) and Single Document Interface (SDI) functionality.

Communication between the Magic xpa client and the Web server (requester) is compressed while communication between non-Magic xpa clients (such as Web clients) and the Web server (requester) is not. The Magic xpa developer secures these communications using the https protocol. The https protocol (SSL\TLS) encrypts the communication between the client and the Web server and ensures that the server is a trusted one.

Communication between the requester, broker and engine is encrypted using Asymmetrical and Symmetrical encryption. No hard-coded keys are used and it is possible to define the Symmetric encryption mechanism and the key length.

Reason #5: Upgrading to Magic xpa reduces risk versus C#, ASP, or Java

20 Reasons to Migrate Magic eDeveloper, uniPaaS and Magic xpa to .NET by Upgrading Rather than Converting
Reason #5: Upgrading to Magic xpa reduces risk versus C#, ASP, or Java

As Magic customers rely on applications to support key business functions, it is important to ensure that the application resides in the latest fully supported versions of Magic technologies.  The choice for those running applications between Magic eDeveloper to .NET conversion and Magic eDeveloper to C#, ASP or Java conversion is an important decision fraught with risk.

IT risk identification, management and response is a key concern for all enterprise IT departments. Senior executives and management have a responsibility of “Assuring investors and shareholders that a ‘standard of due care’ around mitigating IT risks is being met by the organization.” (IT Governance Institute, COBIT 4.1 Framework, 2007). In an enterprise environment, there is considerable risk in working with unsupported architectures, and this risks non-compliance with federal legislation and SOX guidelines.  In fact, our Fortune 500 customers tell us that the upgrade to Magic xpa is essential to maintaining SOX compliance. We have to note that Magic’s platform is just one piece of the overall architecture of the business computing environment, and as other components of the architecture change, it is important to ensure that all components are compatible.  Hardware, Infrastructure, Operating Systems and Databases that come in touch with Magic Applications, are constantly changing by their respective vendors, and evolving irrespective of the computing technology in use.  Most of these vendors tend to have limited life spans on their deliverables and the needs of a complex computing environment require prudent upgrades of these components.

Reason #5: Upgrading to Magic xpa reduces risk versus C#, ASP, or Java

Infrastructure changes are driven by a number of factors: 1) Lack of available parts for older hardware may lead to BIOS, processor or other incompatibilities; 2) Operating System versions that are under cease-of-support and end-of-life conditions; 3)  Enterprise IT mandates and “green” initiatives; 4) Change-of-behavior or discontinued features in databases, middleware and other components. Indeed, upgraded operating systems and database versions often provide tremendous advantages in terms of performance, integrity and security.  Should an infrastructure component upgrade be unsupported by the older application platform technology, there is considerable risk that business operations could be disrupted:

a)    Because the unsupported component may cause the Magic technology to become unpredictable, or cease to work altogether.
b)    Because an older component may fail and it may be difficult to source an older compatible replacement.
c)    The older the version, the less the likelihood of available service-level agreements, warranties, support or the human resources knowledgeable about older technologies and problems, this can lead to delays that may take a long time to diagnose and/or resolve.
d)    Development work may increasingly involve complex workarounds and fixes;
e)    Production system down time can increase to unacceptable levels, up to and including complete system failure.
Magic applications are often part of a larger Corporate Enterprise Application Portfolio; it is important that your applications do not become an “island”, with no ability to interact with newer technologies.  The latest versions of Magic xpa 2.x are constantly being updated to take advantage of newer emerging technologies and standards to ensure interoperability with other industry standard technologies including .NET.

Both risk and cost savings are compelling reasons to ensure that all elements of your Magic applications will be utilizing the latest technologies from Magic Software. The IT Governance Institute suggests that the goal of risk response is to “Ensure that IT-related risk issues, opportunities and events are addressed in a cost-effective manner and in line with business priorities.” (IT Governance Institute, Enterprise Risk: Identify, Govern and Manage IT Risk, The Risk IT Framework Exposure Draft, 2009.) The problem with converting to C#.NET, ASP.NET or Java is that they all increase cost and risk. There is much more effort after the conversion to maintaining an application with large programming teams required to accomplish what could be accomplished by a single Magic developer before. Costs skyrocket with the code-centric approaches, risks mount as unending communication cycles are generated by those trying to figure out what the machine generated code does, and bugs spread across the code-base as developers unfamiliar with the language or the business logic introduce new issues and risks that are simply not present when upgrading.

But the time to upgrade is now (actually its way poast time, but not too late). Magic Software removed support for eDeveloper 9.4 in December 2009, while eDeveloper 10.2 was superseded by uniPaaS; and uniPaaS is now superseded by Magic xpa 2.x. 

The importance of moving from eDeveloper 9.4  to Magic xpa in a timely manner, and continuing to leverage the investment made in  Magic applications is only magnified when considering the risk your company is exposed to when not fully migrated to Magic xpa and .NET.

As many businesses continue to expand their vision of a fully integrated Service Oriented Architecture (SOA), Web Services, RIA, SaaS, Green IT, etc., the importance to the business of using the latest Technology Stack available demands high visibility.  The success of your IT team in the eyes of internal business customers depends on your reputation for deployment on Magic Software’s modern extensible platform, Magic xpa Application Platform, which can become an integral part of your enterprise’s world-class technology architecture.

Reason #2: Cost Savings

20 Reasons to Migrate Magic eDeveloper, uniPaaS and Magic xpa to .NET by Upgrading Rather than Converting
Reason #2: Cost Savings

One of the logical fallacies put forward by vendors offering Magic  to .NET conversion is related to the idea of cost savings. When you upgrade to the latest version of Magic xpa you get full access to the .NET platform without all of the manual programming overhead that a non-platform based language like C# automatically entails.

Cost reduction is easily demonstrable in the upgrade from Magic v5-8, eDeveloper and uniPaaS to Magic xpa. Magic Software offers an ROEI Assesment Document to help you calculate the savings made possible by an upgrade versus the significantly higher (order of magnitude) costs associated with converting an application and maintaining it into the future.

Reason #2: Cost Savings

In narrative form, these cost savings can be summarized as follows. First, Magic xpa yields development productivity increases when creating new components, features and enhancements to your Magic application. Second, given the improvements in the development capabilities in Magic xpa, the costs of maintaining or modifying the application vs. C# or Java are reduced by as much as an order of magnitude.  Third, as it is faster to implement Web services, development time and cost will also be reduced with Magic xpa vs. C# and similarly tedious languages. Magic xpa differs from older versions of Magic in the way it implements and consumes Web services. Fourth, by eliminating the need for a database to store code/instructions (Btrieve) , you can save costs by moving to Metadata / XML. It also improves performance for the application & developer.

If you convert older Magic applications to C# or Java code instead of upgrading, your business logic requires manual programming to implement all of these improvements. No one knows this better that the companies who have made the mistake of converting. Their hiring patterns since converting their applications show a marked increase in the need for non-Magic developers. Not only does this leave Magic developers looking for a job, it ends up costing these companies a fortune to hire two to three times more developers to maintain an application in a non-platform environment. Upgrading is a more efficient way to leverage your Magic application and modernize your application. As stated previously, all development becomes manual in C# and Java and loses the significant inherent advantages of platform based computing.
