Abstract:

In various examples, there is a computer-implemented method for providing packages for processing on a computer system. The method creates a secure connection to an enclave and retrieves a quote to verify that the enclave is genuine and that it contains a predetermined process. The predetermined process is configured to create an enclave for itself and determine that an initial state of the computer system is equivalent to a predetermined state based on a quote retrieved from a security module. The predetermined process is further configured to receive a package to be processed by the computer system and cause the processor to process the package outside of the enclave. In response to verifying the enclave, the method provides a package to be processed by the computer system.

Abstract:

A software circuit breaker observes an amount of free memory available in an application server and a duration of a garbage collection process performed by the application server. The application server executes an agent comprising a plurality of processes for monitoring performance of the application server. Based on the amount of free memory and duration of the garbage collection process, the circuit breaker anticipates a likely crash of the application server. In response to anticipating the likely crash, the circuit breaker disables one or more processes of the agent.
