Abstract: An illustrative data storage management system relies on a specially configured proxy server to operate software containers on a proxy server, maintain resources needed by the software containers, and interwork with other system components. Illustratively, a catalog service on the proxy server maintains a software cache according to maintenance rules and also maintains an associated cache catalog. The software containers are generally managed and operated by an illustrative container manager also hosted by the proxy server. The illustrative software cache comprises contents needed by the software containers, such as pre-configured container templates, DBMS software components, lightervisors representing target operating systems, and storage management software for performing test and storage operations. The maintenance rules govern when cache contents should be purged and moved into offline archive copies.

Abstract: In an example, information about interactions by users, via the graphical user interface, with a plurality of items rendered in the graphical user interface, is obtained, the information including a timestamp of a time and date at which the corresponding interaction occurred. A series of operations is performed upon detecting a condition that triggers a ranking of items rendered in the graphical user interface, for each item for which the condition applies. A ranking score is calculated for the item and a decay is applied to the ranking score by applying a Gaussian distribution, using the timestamp of the item as an origin to the Gaussian distribution, producing a decayed ranking score. The items for which the condition applies are then ranked based on their respective decayed ranking scores and a subset is rendered in the graphical user interface in an order matching the ranking.
