  • Netezza EOL: IBM IAS Is a Flawed Upgrade Path Netezza EOL: IBM IAS Is a Flawed Upgrade Path
    Author: Marc Staimer WHITE PAPER Netezza EOL: What You’re Not Being Told About IBM IAS Is a Flawed Upgrade Path Database as a Service (DBaaS) WHITE PAPER • Netezza EOL: IBM IAS Is a Flawed Upgrade Path Netezza EOL: IBM IAS Is a Flawed Upgrade Path Executive Summary It is a common technology vendor fallacy to compare their systems with their competitors by focusing on the features, functions, and specifications they have, but the other guy doesn’t. Vendors ignore the opposite while touting hardware specs that mean little. It doesn’t matter if those features, functions, and specifications provide anything meaningfully empirical to the business applications that rely on the system. It only matters if it demonstrates an advantage on paper. This is called specsmanship. It’s similar to starting an argument with proof points. The specs, features, and functions are proof points that the system can solve specific operational problems. They are the “what” that solves the problem or problems. They mean nothing by themselves. Specsmanship is defined by Wikipedia as: “inappropriate use of specifications or measurement results to establish supposed superiority of one entity over another, generally when no such superiority exists.” It’s the frequent ineffective sales process utilized by IBM. A textbook example of this is IBM’s attempt to move their Netezza users to the IBM Integrated Analytics System (IIAS). IBM is compelling their users to move away from Netezza. In the fall of 2017, IBM announced to the Enzee community (Netezza users) that they can no longer purchase or upgrade PureData System for Analytics (the most recent IBM name for its Netezza appliances), and it will end-of-life all support next year.
