Patent number: 12277451Abstract: A method of provisioning virtual machines (VMs) includes: providing a VM pool that includes a graphics processing unit (GPU)-optimized VM and a non-GPU-optimized VM operating in different clouds. A control plane can receive an indication that a user has submitted a workload request, determine whether a GPU-optimized VM is available and instruct the non-GPU-optimized VM to send the workload to the GPU-optimized VM in a peer-to-peer manner. The GPU-optimized VM computes the workload and returns a result to the requesting VM. The control plane can instantiate a new GPU-optimized VM (or terminate it when the workload is complete) to dynamically maintain a desired number of available GPU-optimized VMs.Type: GrantFiled: February 21, 2022Date of Patent: April 15, 2025Assignee: Omnissa, LLCInventors: Sam Zhao, Bomin Nie, Nan Wang, Jingtao Zhang, Zhifu Jin

Publication number: 20240231878Abstract: Systems and methods are described for injecting chaos into an application based on a determination that network traffic will be at the application when the chaos is injected. In an example, a gateway can receive requests for applications in a system. The gateway can be configured to periodically insert a header into an application request that causes a proxy agent associated with the requested application to request chaos instructions from a server. When chaos instructions are requested, the server can determine whether and what kind of chaos to inject into the application. The server can send instructions to the proxy agent, which can inject chaos according to the instructions. A monitoring agent can then monitor traffic around the application to determine whether other applications and system components behave appropriately in response to the injected chaos.Type: ApplicationFiled: March 31, 2023Publication date: July 11, 2024Inventors: Bomin Nie, Sam Zhao
