Businesses rely on their IT systems infrastructures for mission-critical data and applications. The business impact of even brief failures has led to the need for continuous (or nearly continuous) IT service availability in all circumstances, including disaster conditions. Individual systems can fail, but the end-to-end IT systems infrastructure must always be there to service the business. This issue of the IBM Systems Journal contains 15 papers that describe alternative infrastructure designs and system platform technologies being deployed or proposed by IBM and some of its clients to successfully meet this continuous availability challenge.
