Patent number: 11088925Abstract: Multitier, multitenant architecture of pods comprise multiple stacks with different metrics and workload compositions that constantly change over time. A computer system may identify an overall pod time-to-live (TTL) based on the changing metrics and workloads. The TTL may be a forecasted time that pod remediation is needed to avoid negative impact on pod performance and customer experience. Additionally, the computer system may identify the appropriate remediation(s) for each pod. The computer system may compare and prioritize remediations across a collection of pods with different configurations and workload characteristics based on the TTLs. Other embodiments may be described and/or claimed.Type: GrantFiled: January 22, 2018Date of Patent: August 10, 2021Assignee: SALESFORCE.COM, INC.Inventors: Ana Bertran, Carl Morgenstern, Daisuke Kawamoto, Nicholas Roan, Steve Bobrowski, Sudhish Iyer, Chin Lee, Kunal Vashi, Zahid Rahman
