Abstract: Techniques for implementing a software-as-a-service (SaaS) infrastructure that supports flexible multi-tenancy are provided. In various embodiments, this SaaS infrastructure employs a hybrid design that can flexibly accommodate both single-tenant and multi-tenant instances of a SaaS application. Accordingly, with this infrastructure, a SaaS provider can advantageously support high levels of isolation between certain tenants of its application (as dictated by the tenants' needs and/or other criteria) while keeping the marginal cost of operating the infrastructure as low as possible.

Abstract: A framework for facilitating communication between a multi-cluster management (MCM) system and the clusters managed by the system is provided. According to one set of embodiments, the framework comprises two independent, unidirectional communications channels: a first channel (i.e., “intent channel”) that flows from the MCM system to each cluster, and a second channel (i.e., “data sync channel”) that flows from each cluster to the MCM system. Through the intent channel, the MCM system can deliver control information to each cluster for actuating management changes/operations therein in a manner that is robust against network dropouts and packet loss. Through the data sync channel, the MCM system can collect and process status information from each cluster (such as, e.g., object state transitions triggered by the control information sent via the intent channel) in a manner that can efficiently scale to support large numbers of clusters.

Abstract: Methods and systems for operation upon one or more data processors for biasing a reputation score. A communication having data that identifies a plurality of biasing characteristics related to a messaging entity associated with the communication is received. The identified plurality of biasing characteristics related to the messaging entity associated with the communication based upon a plurality of criteria are analyzed, and a reputation score associated with the messaging entity is biased based upon the analysis of the identified plurality of biasing characteristics related to the messaging entity associated with the communication.

Abstract: Methods and systems for operation upon one or more data processors for assigning a reputation to a messaging entity. A method can include receiving data that identifies one or more characteristics related to a messaging entity's communication. A reputation score is determined based upon the received identification data. The determined reputation score is indicative of reputation of the messaging entity. The determined reputation score is used in deciding what action is to be taken with respect to a communication associated with the messaging entity.

Abstract: Methods and systems for operation upon one or more data processors that classify communications from messaging entities. A method can include receiving a communication that was sent from a messaging entity. A plurality of message classification techniques is used to classify the communication. Each message classification technique is associated with a confidence value which is used in generating a message classification output from the message classification technique. The message classification outputs are combined in order to generate a message profile score. The message profile score is used in deciding what action is to be taken with respect to the communication associated with the messaging entity.
