Abstract: Systems and methods for domain name system (DNS) caching in a distributed processing engine include a first processing engine which may receive a DNS request for accessing a domain from a client. The first processing engine may generate a DNS query for a DNS controller based on the DNS request, The first processing engine may receive a DNS record corresponding to the domain from the DNS controller. The first processing engine may store data corresponding to the DNS record in cache of the first processing engine. The first processing engine may transmit a message including data corresponding to the DNS record for the domain to a second processing engine, to cause the second processing engine to store data corresponding to the DNS record in cache of the second processing engine.

Abstract: Described embodiments provide systems and methods for routing client requests. A device may be arranged intermediary to a plurality of clients and a domain name system (DNS) controller. The device may generate a query for the DNS controller. The query may correspond to a service to be accessed by the clients. The device may receive, from the DNS controller, a response to the query. The response may include a value used by the device to route respective client requests for accessing the service to a corresponding version of a plurality of versions of the service. The device may receive, from a client, a client request for accessing the service. The device may route the client request to one of the versions of the service according to the value included in the response to manage traffic between various versions of the service.

Abstract: Methods and systems for performing application deployments in a computing environment are presented herein. One or more components of the computing environment may perform a canary deployment of an updated version of an application. As the canary deployment is performed, one or more determinations as to whether to continue, stop, or complete the canary deployment may be performed. These determinations may be based on one or more metrics determined by an application delivery controller of the computing environment. The application delivery controller may be configured to divert or forward traffic to application resources that execute the updated version. Additionally, the canary deployment may be performed in an automated fashion.
