摘要： A computer implemented method, a computer program product and a data processing system allocate resources within a computing organization. A hypervisor layer is implemented on an underlying hardware. The hypervisor layer comprises a set of virtual machines. A first pseudo-hypervisor layer is then implemented within a first one of the set of virtual machines of the hypervisor layer. The first pseudo-hypervisor layer comprises a second set of virtual machines. A first software component is located within a first virtual machine of the second set of virtual machines of the first pseudo-hypervisor layer. A second software component is collocated within a second virtual machine of the second set of virtual machines of the first pseudo-hypervisor layer.

摘要： Method, apparatus and computer program product are configured to perform computer monitoring activities; to collect information regarding computer system status during the computer monitoring activities; to detect a problem in dependence on the information collected during the computer monitoring activities; and to determine whether to launch a diagnostic probe when the problem is detected. The monitoring activities may be performed on a periodic or event-driven basis. The determination whether to launch a diagnostic probe is based on a rule included in a hierarchy of rules. The hierarchy of rules is based on problem tickets; system logs; and computer system configuration information.

摘要： A method, data processing system, and computer program product for managing images. A processor unit divides an image for a virtual machine into blocks. The processor unit determines whether to compress the blocks prior to transmitting the blocks to a destination for the image. In response to a determination to compress the blocks, the processor unit compresses the blocks to form a compressed set of blocks. The processor unit sends the compressed set of blocks and any uncompressed blocks remaining in the blocks to the destination for the image.

摘要： Several deterrence mechanisms suitable for content distribution networks (CDN) are provided. These include a hash-based request routing scheme and a site allocation scheme. The hash-based request routing scheme provides a way to distinguish legitimate requests from bogus requests. Using this mechanism, an attacker is required to generate O(n2)amount of traffic to victimize a CDN-hosted site when the site content is served from n CDN caches. Without these modifications, the attacker must generate only O(n) traffic to bring down the site. The site allocation scheme provides sufficient isolation among CDN-hosted Web sites to prevent an attack on one Web site from making other sites unavailable. Using an allocation strategy based on binary codes, it can be guaranteed that a successful attack on any individual Web site that disables its assigned servers, does not also bring down other Web sites hosted by the CDN.
摘要翻译：提供了适用于内容分发网络（CDN）的几种威慑机制。这些包括基于散列的请求路由方案和站点分配方案。基于散列的请求路由方案提供了一种区分合法请求与假请求的方法。使用这种机制，当从n个CDN缓存提供站点内容时，攻击者需要生成O（n2）个流量来伤害CDN托管站点。没有这些修改，攻击者必须只生成O（n）流量才能关闭该站点。站点分配方案可以在CDN托管的网站之间提供足够的隔离，以防止一个网站的攻击使其他站点不可用。使用基于二进制代码的分配策略，可以保证对任何单个网站的成功攻击禁用其分配的服务器，也不会导致其他由CDN托管的网站。

摘要： A method (and system) for managing a distributed-memory parallel application running on multiple servers, includes dynamically moving a plurality of executable program components, where each of the plurality of executable program components are running on one of a plurality of virtual machines, using migration of the virtual machines between physical servers. The load balancing is operated based on a workload of each of the virtual machines and servers, where a virtual machine, or a plurality of virtual machines, are transferred to balance the workload between each of the servers.
