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.

该项目研究并开发了由于软件维护和升级而导致的停机时间的自主机制。该项目解决了操作系统升级和应用程序限制，重点是独立的二进制二进制二进制应用程序。 他们的目标是降低补丁和更新的可能性，即与旧版本固定的环境中“ break”的预期功能 - 在维护期间和之后，同时将littleManagement架空施加了旧版本。 这些贡献主要源于自动化体系结构，该体系结构将应用程序实例无法操作系统实例，从而使要么独立。 通过Web下载传播的结果将提高旧应用程序的可预测性，而无需源代码访问，修改，重新编译，重新链接，重新链接或特定于应用程序的语义知识，并在商品运输系统和硬件上有效，安全地执行。
