Abstract

A system and method are provided for data sharing. A sharing negotiation tool permits at least one consumer application to negotiate a service level agreement on a dataset which is being shared by a tenant application on a cloud. A capacity planner is configured to determine an appropriate allocation of cloud resources to ensure that the service level agreement of the at least one consumer application is satisfied.

Claims

1. A system for data sharing, comprising:

a platform as a service (PaaS);

a plurality of tenants on a cloud;

a plurality of databases on the cloud, the plurality of databases belonging to the plurality of tenants respectively;

a processor running a sharing negotiation tool permitting at least one consumer application to negotiate a service level agreement (SLA) on a dataset which is being shared by a tenant application on the cloud, wherein the sharing negotiation tool facilitates a three-way sharing agreement to be reached among a data owner which is an application that shares data a data consumer which is an application which wants access to data from the data owner, and the platform; and

a capacity planner configured to determine an appropriate allocation of cloud resources to ensure that the SLA of the at least one consumer application is satisfied;

wherein the capacity planner analyzes workloads of the tenant application and at least one consumer application to determine the appropriate allocation of cloud resources, comprising maintaining CP(Ri) Ci and SZ(Ri) Si, where Ri is a node, DB(Ri) is the set of databases that are hosted on Ri, Ci is a computing capacity of Ri, Si is a storage capacity of Ri, CP is defined as the capacity consumption of DiDB(Ri), SZ(Ri) is defined as the storage consumption of DiDB(Ri).

2. The system as recited in claim 1, wherein the sharing negotiation tool provides a communication channel which permits the tenant application and at least one consumer application to identify the dataset which is to be shared.

3. The system as recited in claim 1, further comprising an SLA-aware query dispatcher configured to issue a notification to a database coordinator if the SLA is not being satisfied.

4. The system as recited in claim 1, wherein the at least one consumer application comprises a plurality of applications each having a separate SLA agreement.

5. The system as recited in claim 1, wherein the tenant application provides at least one standard access template which specifies the dataset which is to be shared with the at least one consumer application.

6. The system as recited in claim 1, further comprising a replication manager configured to replicate the dataset to improve throughput.

7. The system as recited in claim 1, wherein the capacity planner determines how data associated with the tenant application and at least one consumer application is to be organized to satisfy the SEA.

8. The system as recited in claim 1, further comprising a search interface which permits the at least one consumer application to search for a dataset in the cloud which is to be shared.

9. A method for data sharing, comprising:

negotiating a service level agreement (SLA) on a dataset which is to be shared by a tenant application on a cloud platform as a service (PaaS) including a processor, a plurality of tenants on a cloud, a pluarality of databases on the cloud, the plurality of databases belonging to the plurality of tenants respectively, wherein the tenant application is stored on a computer readable storage medium on the cloud;

facilitating a three-way sharing agreement to be reached among a data owner which is an application that shares data, a data consumer which is an application which wants access to data from the data owner, and the platform;

determining an appropriate allocation of cloud resources to ensure that the SLA of the at least one consumer application is satisfied

analyzing workloads of the tenant application and at least one consumer application to determine the appropriate allocation of cloud resources, comprising maintaining CP(Ri) Ci and SZ(Ri) Si, where Ri is a node, DB(Ri) is the set of databases that are hosted on Ri, Ci is a computing capacity of Ri, Si is a storage capacity of Ri, CP is defined as the capacity consumption of DiDB(Ri), SZ(Ri) is defined as the storage consumption of DiDB(Ri).

10. The method as recited in claim 9, further comprising providing a communication channel which permits the tenant application and at least one consumer application to identify the dataset which is to be shared.

11. The method as recited in claim 9, further comprising issuing a notification to a database coordinator if the SLA is not being satisfied.

12. The method as recited in claim 9, wherein the at least one consumer application comprises a plurality of applications each having a separate SLA agreement.

13. The method as recited in claim 9, wherein the tenant application provides at least one standard access template which specifies the dataset which is to be shared with the at least one consumer application.

14. The method as recited in claim 9, further comprising replicating static datasets if it is determined that throughput can be improved.

15. The method as recited in claim 9, further comprising determining how data associated with the tenant application and at least one consumer application is to be organized to satisfy the SLA.

16. The method as recited in claim 9, further comprising providing a search interface which permits the at least one consumer application to search for a dataset in the cloud which is to be shared.

17. A system for data sharing, comprising:

a platform as a service (PaaS);

a plurality of tenants on a cloud;

a plurality of databases on the cloud, the plurality of databases belonging to the plurality of tenants respectively;

a sharing negotiation tool comprising;

a service level agreement (SLA) negotiator configured to facilitate the creation of a SLA on a dataset which is shared by at least one consumer application and a platform as a service (PaaS) provider;

a communication tool configured to facilitate a three-way sharing agreement among a data owner which is an application that shares data, a data consumer which is an application which wants access to data from the data owner, and the platform;

a search interface which permits the data consumer to search for a dataset in the cloud;

a capacity planner configured to determine an appropriate allocation of cloud resources to ensure that the SLA of the at least one consumer application is satisfied;

wherein the capacity planner analyzes workloads of the tenant application and at least one consumer application to determine the appropriate allocation of cloud resources, comprising maintaining CP(Ri) Ci and SZ(Ri) Si, where Ri is a node, DB(Ri) is the set of databases that are hosted on Ri, Ci is a computing capacity of Ri, Si is a storage capacity of Ri, CP is defined as the capacity consumption of DiDB(Ri), SZ(Ri) is defined as the storage consumption of DiDB(Ri).
