EGL Is Green

Reuse is not a new idea, it's an "old school" mantra from the early 1990’s when objects and CORBA were all the rage (remember AD/Cycle? Grunge?). The more things change, the more they stay the same. We've been talking about the value of reuse for a long time now. The promise of reuse is compelling however it has not been widely adopted as a practice. Technology has made great strides in helping us reuse code more effectively, but at the end of the day most companies have had a hard time turning this potential into reality.
Why? Because it's hard. Regardless of the enabling technologies, reuse takes time, commitment and coordination. SOA and Jazz will help with future endeavors but today we are still bound by our history. The legacy code that runs the world’s systems today is not going away. On the contrary, it's growing. Gartner estimates there are over 230 billion lines of COBOL and RPG code in existence today with 5 billion added annually. We have to find ways to reuse this code.
Over the past 15 years, most technology advancements have manifested themselves as client and middleware solutions (i.e. browser technology and J2EE application servers). However, not much has changed with respect to the languages used to develop the legacy code? Now we have a new language that addresses this problem, EGL. IBM is the only company capable of creating a new language that easily interoperates these older technologies with the new technologies of SOA and Web 2.0.
EGL allows us to easily reuse and modernize existing code. We must extend what has already been built and utilize EGL to reduce the time and energy it takes to accomplish this. This is a requirement, not an option. At ClearBlade we are developing EGL design patterns and frameworks for reuse called Green Code. As we complete this code, we will make it available to the EGL Cafe to do our part to promote reuse.
We have no choice but to embrace, extend and reuse the legacy code in existence today. Rewriting and replacing existing code is not financially viable nor is it socially responsible. Reuse of our existing code saves energy by repurposing what we alreay have. Reuse is green, EGL is green.
