Distributed system controllers provide on-demand data access in complex, heterogenous data storage. In one embodiment, the distributed system controllers respond to name space metadata event messages published on a persistent message but to maintain a common name space in a complex of heterogenous data storage systems. In one embodiment, data unit access request metadata messages are propagated in recursive, cascading hops along a persistent message bus until the requested data unit is located and retrieved. Other features and aspects may be realized, depending upon the particular application.

Distributed system control for on-demand data access in complex, heterogenous data storage

Software and resources, pre-deployed in accordance with a disaster recovery policy, are placed in a standby state to provide rapid disaster recovery in a cloud storage environment. When a disaster recovery situation is detected, (for example a loss of access to primary data), the pre-deployed resources are immediately activated according to the disaster recovery policy to provision and re-configure adequate resources and rapidly restore access to the data (such as restoring data from cloud backup storage). A disaster recovery situation may involve, for example, loss of hardware availability, network bandwidth interruption, or a sudden and large unforeseen jump in storage retrieval request volume (for example a recall storm).

Scaling out a hybrid cloud storage service

A method, programmed medium and system are provided for enabling a slider bar to change 'mode' or 'purpose', based on feedback from the graphical user interface (GUI). In one exemplary embodiment, a slider functions in usual manner but an audible or video signal is provided as each tab, window or object in a plurality of tabs, windows or objects is scrolled through. Within a specific time interval of feedback action, the user may stop and pause the movement of the cursor. This causes the tab, window or object to open and the slider bar mode to change from selecting to scrolling through the content of that specific tab, window or object. In another example, in addition to the &#x201c;pause&#x201d; action, the enhanced slider bar would accept movement perpendicular to the normal direction of slider bar movement, as indication that a new function is to be performed.
