A security system used by an organization maintains a PKI used for issuing digital certificates (hereinafter for brevity also referred to simply as 'certificates') and provides the PKI to the organization as a network service. In order to simplify the use of the PKI for purposes such as obtaining certificates, the security system additionally provides a mechanism for using a designated flow protocol to interface with whichever MDMs the organization uses. This mechanism permits administrators or other users to provision certificates to their organization's client devices with just a few actions within a user interface.

Computer network-based service for generation and installation of digital certificates of a public key infrastructure seamlessly integrating with multiple mobile device management systems

A multi-tenant system provides software-updating functionality that selectively updates tenant systems according to a number of different factors. In some embodiments, the factors include evaluation of 'health metrics' that quantify how well tenant systems are functioning after an update of software components to the latest version, policies specified by either the tenants or the multi-tenant system (or both), and/or 'kill switches' specified by the multi-tenant system that prevent updating, as some examples.

Software update distribution within a multi-tenant architecture

Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a clustered storage system. The metadata is collected from one or more storage volumes and then provided to a catalog module. The catalog module pre-processes the metadata and then generates a searchable data structure. The searchable data structure may then be used to respond to a user request for information regarding the storage system.

Embodiments of the present invention provide a novel technique for maintaining directory-based quota, for performing directory notification to a client system, and performing other such operations by efficiently finding ancestral directory associations on a server system without performing multiple accesses to data structures associated with the directory associations. Since data structures do not need to be accessed multiple times, performance of the server system can be improved.

Mechanism for performing fast directory lookup in a server system

A new approach to support efficient management of directory quotas for a file system is proposed. The approach adopts bitmasks for files and directories in a file system, and transforms the problem of maintaining and traversing complicated file system data structures into a simple bitmask comparison and an associated lookup. It applies to files and directories under CIFS, NFS, other network file systems and local file systems and moves the costly operations of traversing the file system from file operations to administrative operation of switching the quotas on and off, which is infrequent and do not have the performance requirements of regular file operations.
