Abstract: A cloud distributed application runtime is deployed to execute a cloud infrastructure. During deployment of an application service by the cloud infrastructure, each action implemented in the cloud infrastructure is traced, from an initiation of the application service to a termination of the application service. Level objectives associated with the cloud infrastructure and associated with the application service deployed by the cloud infrastructure are tracked. In response to tracing an action implemented in the cloud infrastructure and in response to tracking the level objectives, a scaling decision associated with the application service is determined. The scaling decision incudes either an upscaling or a downscaling. In response to determining the scaling decision, the scaling decision is implemented to match the level objectives associated with the cloud infrastructure and associated with the application service.

Abstract: Example methods are provided a computer system to perform context-aware domain name system (DNS) query handling in a software-defined networking (SDN) environment. One example method may comprise detecting a DNS query to translate a domain name; identifying DNS record information that translates the domain name to a network address assigned to a virtualized computing instance; and identifying context information that is associated with the virtualized computing instance and mapped to the DNS record information. The method may also comprise: in response to detecting a potential security threat based on the context information, performing a remediation action to block access to the virtualized computing instance; but otherwise, generating and sending a DNS reply specifying the network address assigned to allow access to the virtualized computing instance.

Abstract: System and method for performance control in a cloud computing environment uses dependency hierarchy between software entities executing in the cloud computing environment and operational status of each of the software entities executing in the cloud computing environment. Using the dependency hierarchy between the software entities and the operational status of each of the software entities, a scaling operation is performed to the virtual computing instances such that a service-level objective (SLO) of the cloud computing environment satisfies a predetermined threshold.
