Application Modernization is a commonly used term covering a wide range of practices and technologies. As the world emerges from recession there is growing interest in applying modernization techniques and technologies to reduce complexity and cost and respond to rapidly changing, post recession business models. In this report we explore how the CBDI SAE framework can be evolved to provide a repeatable, business driven backplane for effective application modernization practice.

Introduction

We are all acutely conscious of the disastrous state of the typical application portfolio and the constraints placed upon business by inherently high cost, complexity and inflexibility. Whilst this has been true for many years, it's clear that post recession business pressures are increasing the priority to address the issue.

No surprise Application Modernization (AM) is rapidly becoming a mainstream strategy.

While AM has been around for many years, there are many interpretations of the concept. Most modernization efforts appear to be focused on the technology, evidenced by the thriving market in tools, technologies and resources for language and platform migrations including virtualization of server and network. The same cannot be said for business focused modernization.

Results from a recent industry survey make clear that a majority of IT leaders are planning AM initiatives. Further, a significant proportion is also planning to make SOA the core target architecture.

SOA won't be the only architecture concept in use, but it will be the dominant influence because it addresses many of the limitations of current AM efforts. It focuses on key outcomes including business agility and reuse, and creates an integration architecture that is equally useful in modernization and rationalization as it is in responding to unforeseen business requirements. And many business and IT leaders are anticipating the next decade will be more turbulent that the last.

Figure 1 illustrates how a structured AM approach could be organized. The challenge is to re-architect existing systems in context with the To-Be business and selectively harvest assets to accelerate business delivery programs that rapidly deliver an SOA based on better structure at all layers of the architecture. This process is supported by cross cutting capabilities for project management, information architecture, business case analysis and transition strategy, management and coordination.

Everware-CBDI has developed the Service Architecture & Engineering (SAETM) Framework over the past five years to create a backplane for structured, repeatable SOA activity. The framework is distinctive being:

  • Business driven
  • Strongly data oriented
  • Meta model based

In this report we will outline how the framework can support the AM process. We will refer to the enhanced framework as SAE2.
