Patent number: 11909612Abstract: Some embodiments provide a novel method of performing health monitoring for resources associated with a global server load balancing (GSLB) system. This system is implemented by several domain name system (DNS) servers that perform DNS services for resources located at several geographically separate sites. The method identifies several different groupings of the resources. It then assigns the health monitoring of the different resource groups to different DNS servers. The method then configures each particular DNS server (1) to send health monitoring messages to the particular group of resources assigned to the particular DNS server, (2) to generate data by analyzing responses to the sent health monitoring messages, and (3) to distribute the generated data to the other DNS servers. The method in some embodiments is performed by a set of one or more controllers.Type: GrantFiled: January 28, 2023Date of Patent: February 20, 2024Assignee: VMware LLCInventors: Murali Basavaiah, Anand Parthasarathy, Sreeram Iyer, Sambit Kumar Das, Narasimhan Gomatam Mandeyam

Patent number: 11909719Abstract: Techniques and technologies for an Internet Protocol (IP) address management (IPAM) system to track and manage IP address workflows in a network. The IPAM system can be used to define and enforce management policies or rules regarding IP address management, such as allocation policies, refill policies, and so forth. For instance, the IPAM system can enforce allocation policies that define rules to allow or deny allocation of IP addresses based on types of resources for which the IP addresses are requested, registered user accounts that are requesting the IP addresses, the purpose of the resources receiving the IP addresses, and so forth. Additionally, the IPAM system can enforce refill policies that define rules for replenishing inventories of IP addresses that have been allocated for different domains in the network. The IPAM system can improve the management of IP address workflows by enforcing policy and tracking IP address workflows in networks.Type: GrantFiled: November 24, 2021Date of Patent: February 20, 2024Assignee: AMAZON TECHNOLOGIES, INC.Inventors: Jonathan Paul Kramer, Michael Erik Untereiner, Samuel Lough, John Jeffrey Schlachtenhaufen, Masood Karimi, Eric Andrew Rubin-Smith, Joshua D Leaverton, Shovan Kumar Das
