Abstract: Systems and methods for enhancing the availability of multi-tier applications on cloud computing platforms are disclosed. An example method comprises identifying, using a processor, dependencies among application components in a multi-tier application; generating, using the processor, an application blueprint defining the multi-tier application based on the identified dependencies; generating a remediation policy based on the identified dependencies in the application blueprint, the remediation policy comprising instructions to restore availability of the multi-tier application; detecting unavailability of the multi-tier application; identifying, using the processor, one of the application components as being responsible for the unavailability of the multi-tier application; and restarting, using the processor, the identified one of the application components based on the remediation policy to restore availability of the multi-tier application.

Abstract: Methods, apparatus, systems and articles of manufacture to monitor virtual computing environments are described. An example method includes determining a computing resource status of a computing host that is operating a container engine, comparing the computing resource status to a threshold, and in response to determining that computing resource status does not exceed the threshold, executing a monitoring operation in a container hosted by the container engine.

Abstract: Methods and systems to limit the duration of a service interruption caused by a failed middleware application server are disclosed. One example method and system includes monitoring the operational status of a first virtual machine operating as a primary server and the operational status of a second virtual machine operating as a stand-by server and, based on the monitored operational status of the first and second virtual machines, performing a hot-swap to cause the second virtual machine to operate as the primary server and the first virtual machine to operate as the stand-by server. The first and second virtual machines are implemented on a same host processing system. After the hot-swap, the first virtual machine is restarted. In some examples, the first virtual machine and the second virtual machine are implemented on a same host processing system.
