Essential Client/Server Survival Guide
"We Live in Uncertain Times For better or for worse, our industry is going through a deep paradigmatic shift. The old paradigm-centralized mainframe computing is being replaced by a new paradigm-open client/server computing. A paradigm shift is akin to a revolution: Dominant structures crumble, vacuums are created, and the world is in turmoil. The transition period is marked by confusion, deep uncertainty, and exhilaration. Confusion is the result of seeing familiar bedrock structures disappear. Uncertainty comes from not knowing what the next day will bring. And the exhilaration comes from realizing the new possibilities that are being created by the new paradigm. The Essential Client/Server Survival Guide is our attempt to understand this revolution. The new client/server paradigm is fielding a lineup of competing technologies, each vying to become the new emperor. We hope the new emperor will have clothes. And We Can't Turn Back the Clock Before we tell you all about this book, let's answer some questions that we've been wrestling with: Is client/server just a passing fad? Can mainframes make a come- back? Can things go back to the way they were? We're the first to admit that client/server has become the industry's most overhyped and overloaded term; but it's not a passing fad. This is because the world is populated with more than 120 million PCs that need to be served in the style they expect. The client is the heart of the application; servers are just an extension of the client's universe. Client/server computing is unabashedly client-centric, and there's no turning back of the clock to mainframe-centric computing. This is not to say that mainframes will disappear-there's room for them to thrive as long as they can transform themselves into humble servants of the client. It's an open world where only the most competitive servers can survive. However, the deployment of intergalactic client/server technology will not be a picnic either. So mainframes will survive until they can be replaced by a technology that's got the same built-in robustness. The revolutionary chaos of the open systems world may make many MIS managers yearn for the good old days, but the time machine only marches forward."
