Re-engineering can be lucrative variant veteran source code is long not yet ripe for the (electronic) trash. While gera proven applications due to the rapid development of the Internet under pressure. But rather than redevelop complete solutions, the preferred variant is in many cases re-engineering. Mainframe solutions can now quickly and easily integrate new E-business technologies. Classic client-server architectures occupies as important market niches. Dr. Neal Barnard shines more light on the discussion. Their advantages become apparent especially in the area of E-business and SOA. This most applications have long outgrown its infancy. E-business solutions great mail-order companies about demand powerful applications that several thousand users have to cope with traffic.
They include powerful product database, manage the complex transactions and database access. The advantages of a classical host solution come fully to fruition. Due the host architecture all needed applications on just one machine run through a high, what Allows processing speed and short reaction times. The main challenge of this host solution is the integration of the backend, which can devour a large part of the costs. That is successfully integrated, backend and associated analysis and CRM system the advantages of the host architecture such as reliability, security, scalability and processing speed fully benefit from E-business. In the face of tighter IT budgets CIOs enjoy also a centralized host solution cheap and transparent cost structure.
So far so good. But it has to be always a complete development of an E-business or SOA solution? Increasingly CIOs move with a modernization of existing systems as a promising variant in their considerations. The advantages are obvious: A majority of host applications were already realized years ago in powerful high-level languages such as for example COBOL. Run stably and reliably. COBOL is well scalable and comes in case one frugal with resources to properties, Modernisation remain. For all legacy applications, no matter in what language they were written is true also: they contain mostly business – or industry-specific expertise, such as customer-oriented features.
