A computer implemented method, system, and computer program product comprising intercepting an interaction with a data storage capability at the abstraction layer enabled to intercept data interactions for different types of data storage capabilities; wherein the interaction changes data on the data storage capability; sending a copy of the interaction to a replication data storage capability; and sending the interaction to the data storage capability.

Abstraction layer

In one aspect, a method includes migrating a database object from a source database to a target database, updating a storage of the location of the DB object to be the target database, directly accessing one of the target database and the source database during the migrating and executing, during the migrating, a database command by retrieving the DB object from the other one of the target database and the source database.

Database migration

According to one embodiment, a request is received for estimating migrating a first dataset from a first cloud system to a second cloud system. A migration cost estimation module determines a network bandwidth required to migrate the first dataset from the first cloud system to the second cloud system, determines a duplicated data time period during migration that the first dataset has to be maintained by both the first cloud system and the second cloud system for service continuity, and determines a total cost of migrating the first dataset from the first cloud system to the second cloud system based on the required network bandwidth and the duplicated data time period. It is then determined whether to migrate the first dataset from the first cloud system to the second cloud system based on the total cost.

Multi-cloud data migration in platform as a service (PAAS) environment

In general, the invention relates to a method and system for migrating tables in databases. The method may include calculating a first plurality of migration factors for a first set of tables in a source database using a plurality of pre-calculated factors and a first plurality of dynamically-calculated factor, where each of the first plurality of migration factors is associated with one of the first set of tables. The method may further include selecting a first table from the first set of tables to migrate based on the first plurality of migration factors; and migrating the first table to a target database.

Database monitoring for online migration optimization

In one example, a method includes generating an enhanced copy, which includes application data generated from using an application, the application, a configuration of the application and runtime settings to run the application. The method also includes restoring at least one of the application, the configuration of the application and the runtime settings using the enhanced copy.

Storing application data as an enhanced copy

Disclosed are techniques for use in authentication. In one embodiment, the techniques comprise a method. The method comprises the step of receiving a request comprising a plurality of attributes. The method also comprises determining whether to grant authentication or to perform an assessment of at least some of the attributes. The said determination is dependent on whether one of the attributes corresponds with a predictor.

Method, apparatus and article of manufacture for fast tracking authentication

Techniques of detecting malicious events involve generating a relational graph of event data describing events that occur within a specified, limited time window. Along these lines, a malicious event detection computer receives event data describing interactions between entities such as users, devices, and network domains from various servers that occur within a specified time window. In response, the malicious event detection computer generates a relational graph that has graph structures (e.g., nodes and edges) representing these interactions. Analysis of patterns within the resulting relational graph indicates whether there is a malicious event occurring.

Detecting malicious online activities using event stream processing over a graph database

An improved adaptive authentication technique involves defining a window array which stores the number of distinct fact values per time unit over a predetermined number of time units. Each element of the window array has a value set to the number of distinct fact values over a time unit. The window array is stored in a database. Under the improved technique, upon a user initiating an authorization request, the risk engine extracts the request and the window array from the database into a cache on the authorization server. The risk engine uses the request which contains a value of the fact to adjust values of the elements of the window array and, once the adjusting is completed, computing the fact velocity which is used in the determination of a risk score for the request.
