The project investigates and develops autonomic mechanisms forreducing system downtime due to software maintenance and upgrades.The project addresses operating system upgrades and also applicationupgrades, focusing on standalone binary-executable applications. Themain goal is to lessen the possibility that patches and updates will``break'' expected functionality of the environment that worked finetogether with the old version -- overall maximizing availability andreliability both during and after maintenance while imposing littlemanagement overhead. The contributions stem primarily from avirtualization architecture that decouples application instances fromoperating system instances, enabling either to be independentlyupdated. The results, disseminated via web download, will improveavailability of legacy applications, with no source code access,modification, recompilation, relinking or application-specificsemantic knowledge, and perform efficiently and securely on commodityoperating systems and hardware.

该项目调查并开发了自主机制，以减少由于软件维护和升级而导致的系统停机时间。该项目涉及操作系统升级和应用程序升级，重点是独立的二进制可执行应用程序。主要目标是减少补丁和更新将“破坏”与旧版本一起工作的环境的预期功能的可能性-在维护期间和之后最大化可用性和可靠性，同时施加很少的管理开销。这些贡献主要来自虚拟化体系结构，它将应用程序实例与操作系统实例解耦，使两者都能够独立更新。通过网络下载传播的结果将提高遗留应用程序的可用性，无需访问源代码、修改、重新编译、链接或特定于应用程序的语义知识，并在商用操作系统和硬件上高效、安全地执行。
