This e-book fills a niche among high-level review texts which are frequently too common and low-level aspect orientated technical handbooks that lose sight the "big picture". This publication discusses SOA from the low-level standpoint of middleware, a number of XML-based applied sciences, and simple carrier design. It additionally examines broader implications of SOA, really the place it intersects with company technique administration and method modeling. Concrete overviews should be supplied of the methodologies in these fields, in order that scholars may have a hands-on snatch of ways they are utilized in the context of SOA.

While this architecture distributes the processing load over several application servers, failure of the back-end database server may be an issue. Therefore, the architecture includes a “hot standby” server that is intended to take over if the primary fails. The database server logs its updates at the standby server with some frequency. If the primary fails, the standby takes over as a new primary server. There may be a delay in this process while the standby completes the performance of the update operations that were logged by the primary.
This is typically a database or a legacy resource, for example Customer Information Control System (CICS) applications for transaction processing. 2. At the application tier, the business or application logic leverages that resource to support an enterprise application. For example, this may be an e-commerce application that utilizes a back end database to record transactions. 3. At the client or presentation tier, the presentation logic is the interface between the application and its clients, where the latter may be users or other applications.
At the client or presentation tier, the presentation logic is the interface between the application and its clients, where the latter may be users or other applications. Early enterprise applications ran on mainframe computers and all three tiers were, to a large extent, centralized on the mainframe: data in files or databases, application logic written in COBOL or PL/1, and presentation logic based on 3270 terminals (“green screens”). This is depicted in Fig. 1. The classic exemplar of such single-tier systems is CICS, still the most widely used software system in the world, with over 20 billion CICS transactions occurring daily at the time of writing.
