Multi-Tenant Database Management For Service Level Agreement (Sla) Profit Maximization

US Patent:
8380557, Feb 19, 2013
Filed:
Jan 5, 2011
Appl. No.:
12/985057
Inventors:
Hyun Jin Moon - Newark CA,
Junichi Tatemura - Cupertino CA,
Vahit Hakan Hacigumus - San Jose CA,
Shenoda Guirguis - Pittsburgh CA,
Yun Chi - Monte Sereno CA,
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06Q 10/00
US Classification:
705 728, 705 1446, 705705, 705348, 705 262, 705400, 705 722, 705 736, 705 738, 705 739
Abstract:
Systems and methods are disclosed to consolidate workload on cloud-based computers by co-locating one or more high-penalty tenants on one or more cloud-based servers; reducing service level agreement (SLA) violations by over-provisioning the cloud-based server; and maximizing an SLA profit.

Constraint-Conscious Optimal Scheduling For Cloud Infrastructures

US Patent:
2011017, Jul 14, 2011
Filed:
Jun 18, 2010
Appl. No.:
12/818514
Inventors:
Hyun Jin Moon - Newark CA,
Vahit Hakan Hacigumus - San Jose CA,
Yun Chi - San Jose CA,
Assignee:
NEC LABORATORIES AMERICA, INC. - Princeton NJ
International Classification:
G06Q 10/00
G06Q 50/00
US Classification:
705 712, 705301
Abstract:
Systems and methods are disclosed to schedule jobs in a cloud computing infrastructure by receiving in a first queue jobs with deadlines or constraints specified in a hard service level agreement (SLA); receiving in a second queue jobs with a penalty cost metric specified in a soft SLA; and minimizing both constraint violation count and total penalty cost in the cloud computing infrastructure by identifying jobs with deadlines in the first queue and delaying jobs in the first queue within a predetermined slack range in favor of jobs in the second queue to improve the penalty cost metric.

US Patent:
2012026, Oct 18, 2012
Filed:
Oct 10, 2011
Appl. No.:
13/270218

Assignee:
NEC LABORATORIES AMERICA, INC. - Princeton NJ
International Classification:
G06F 17/30
US Classification:
707694, 707E17005
Abstract:
Systems and methods are disclosed for a swap-based multitenant database load balancing (SWAT) by finding an optimal swap set that eliminates hotspots, and finding a sequencing and parallelization of swap executions for the multi-tenant database.

US Patent:
2013021, Aug 15, 2013
Filed:
Nov 21, 2012
Appl. No.:
13/683849
Inventors:
Hyun Jin Moon - Newark CA,
Yun Chi - Monte Sereno CA,
Vahit Hakan Hacigumus - San Jose CA,
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
G06F 17/30
US Classification:
707609
Abstract:
Systems and methods for consolidating workload on one or more computing devices, comprising: generating tenant performance profiles for at least one of a buffer memory size and a buffer warmness; assigning one or more tenants to a database management system (DBMS) instance; configuring the one or more tenants to minimize a total server count needed to host the one or more tenants; and reducing the total server count by adjusting of buffer sizes while satisfying Service Level Agreement (SLA) requirements.
