In representative embodiments, multiple cloud computing infrastructures, each having its own application and management fabric, coexist with in the same cloud computing infrastructure. This results in a cloud computing infrastructure where multiple management fabrics and application fabrics coexist to offer their own services and cross platform services. Each functions independently and also communicates with each other to offer high availability and disaster recovery. One application and management infrastructure is a host to the other application and management infrastructure. The hosted infrastructure accesses underlying fabrics through the host infrastructure. A resultant system comprises a common hardware fabric, a common runtime, and a service fabric comprising services from both the host and hosted infrastructures.

Multi-service application fabric architecture

Technologies are described herein for launching an online support chat session in response to an occurrence of a support event on a personal computer and transmitting detailed event information via the chat session for display to support personnel. When an error or other event occurs on a computer, an online support chat session is established using an online support chat client associated with the error or event. The pertinent information about the error or event along with additional data regarding the computer and the user are transmitted via the online support chat session for display to the support personnel.

Initiating a support chat session in response to the occurrence of a support event with transmission of detailed event information

A computer event is detected and a notification is displayed. If a dialog box corresponding to the computer event triggered the event detection, then the dialog box is modified to include further details of the event and an assistance control that links to a search engine Web page. If a dialog box did not trigger the event detection, then a dialog box is displayed with the event details and assistance control. Upon selection of the assistance control, the search engine Web page is displayed with event details pre-populated in the search term field. Targeted advertisements are displayed according to bidding on a unique descriptor associated with the specific computer event.

Computer system event detection and targeted assistance

A method of removing metadata from a database in a multimode replication system includes establishing a metadata retention period for nodes in the system as well as associating changes with nodes on the system. The system responds to an expiration of the retention period for any one node by analyzing the associated changes and nodes and determining if the change affects data shared with other nodes. If the data is shared with other nodes then the expired retention period node metadata is removed from the system. If the expired metadata retention period node does not share the changes with other nodes, the metadata is not removed. This allows any unique changes to still be entered into the database without adversely affecting other nodes.

Method and system for partition level cleanup of replication conflict metadata

Generally described, embodiments of the present invention provide the ability to assign primary keys and foreign keys to lists of any number of sites that are maintained by a database hosting service. More specifically, a scalable table, like the master table described below, may continue to be used without specifying primary keys or foreign keys within the table by using two additional tables in which the keys are specified for each list of each site. Integrity may be maintained by confirming that all changes to either a primary key or foreign key are appropriate before applying the changes to the master table.

Implementing referential integrity in a database hosting service

The present invention provides for facilitating synchronization in a data source/data destination environment using data replicas. When a plurality of destinations request synchronization with a source, a first destination selected for synchronization is processed such that differences between the first destination data and source data is determined and persisted in a partition update. After updating the first destination, the synchronization process continues only for those remaining destinations that will be affected by the partition change, as determined by the persisted data, and then as updated by the persisted data.
