Abstract

The computer detects a request from a first computer to store a data item, and determines if a volatile memory in a second computer comports with an isolation rule for the data item. In response to determining that the volatile memory in the second computer comports with the isolation rule for the data item, the computer compares access time for data in the volatile memory in the second computer with access time for data in a local hard drive in the first computer, and then selectively stores the data item in a storage location that has a lower access time. The computer establishes a threshold resource consumption rate for both the volatile memory in the second computer and the local hard drive in the first computer to further select the volatile memory in the second computer or the local hard drive in the first computer to store the data item.

First claim

What is claimed is:

1. A computer system comprising one or more processors, one or more computer readable memories, and one or more computer readable storage mediums, and program instructions stored on at least one of the one or more storage mediums for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:
program instructions to detect a request from a first computer to store a data item;
program instructions to determine if a volatile memory in a second computer comports with an isolation rule for the data item, wherein the isolation rule prohibits sensitive data from two companies co-residing on the volatile memory, wherein comporting with the isolation rule permits the data item to be stored in the volatile memory in the second computer;
program instructions to, in response to determining that the volatile memory in the second computer comports with the isolation rule for the data item, compare access time for data in the volatile memory in the second computer with access time for data in a local hard drive in the first computer;
program instructions to selectively store the data item in a storage location that has a lower access time, wherein the storage location is either the volatile memory in the second computer or the local hard drive in the first computer as determined by the lower access time;
program instructions to establish a threshold resource consumption rate for both the volatile memory in the second computer and the local hard drive in the first computer, wherein the threshold resource consumption rate sets a maximum permissible level of ancillary resources used to access the volatile memory in the second computer or the local hard drive in the first computer;
program instructions to further select the volatile memory in the second computer or the local hard drive in the first computer to store the data item according to whether the volatile memory in the second computer or the local hard drive in the first computer has a lower threshold resource consumption rate relative to one another; and
program instructions to, in response to determining that a volatile memory in a third computer has a lower access time than the volatile memory in the second computer or the local hard drive in the first computer, move the data item from the volatile memory in the second computer to the volatile memory in the third computer.

2. The computer system of claim 1 further comprising: program instructions to determine that the volatile memory in the second computer does not comport with the isolation rule due to incompatible data being stored in the volatile memory in the second computer, wherein the incompatible data is sensitive data from two different companies;
program instructions to determine that the data item has a higher priority for being accessed by the first computer than the incompatible data that is currently stored in the volatile memory in the second computer; and
program instructions to move the incompatible data to a hard drive on the second computer and storing the data item in the volatile memory in the second computer.

3. The computer system of claim 1 , wherein the first computer and the second computer are in a cloud computing environment.

4. The computer system of claim 1 , further comprising:
program instructions to dynamically adjust the threshold resource consumption rate according to a higher fee associated with the ancillary resources associated with either the volatile memory in the second computer or the local hard drive in the first computer.

5. A computer system comprising one or more processors, one or more computer readable memories, and one or more computer readable storage mediums, and program instructions stored on at least one of the one or more storage mediums for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:
program instructions to detect a request from a first computer to store a data item;
program instructions to determine if a volatile memory in a second computer comports with an isolation rule for the data item, wherein the isolation rule prohibits sensitive data from two companies co-residing on the volatile memory, wherein comporting with the isolation rule permits the data item to be stored in the volatile memory in the second computer;
program instructions to determine that the volatile memory in the second computer does not comport with the isolation rule due to incompatible data being stored in the volatile memory in the second computer, wherein the incompatible data is sensitive data from two different companies;
program instructions to determine that the data item has a higher priority for being accessed by the first computer than the incompatible data that is currently stored in the volatile memory in the second computer;
program instructions to move the incompatible data to a hard drive on the second computer and storing the data item in the volatile memory in the second computer;
program instructions to selectively store the data item in a storage location that has a lower access time, wherein the storage location is either the volatile memory in the second computer or the local hard drive in the first computer as determined by the lower access time;
program instructions to establish a threshold resource consumption rate for both the volatile memory in the second computer and the local hard drive in the first computer, wherein the threshold resource consumption rate sets a maximum permissible level of ancillary resources used to access the volatile memory in the second computer or the local hard drive in the first computer;
program instructions to further select the volatile memory in the second computer or the local hard drive in the first computer to store the data item according to whether the volatile memory in the second computer or the local hard drive in the first computer has a lower threshold resource consumption rate relative to one another; and
program instructions to, in response to determining that a volatile memory in a third computer has a lower access time than the volatile memory in the second computer or the local hard drive in the first computer, move the data item from the volatile memory in the second computer to the volatile memory in the third computer.

6. The computer system of claim 5 , wherein the first computer and the second computer are in a cloud computing environment.

7. The computer system of claim 5 , further comprising:
program instructions to dynamically adjust the threshold resource consumption rate according to a higher fee associated with the ancillary resources associated with either the volatile memory in the second computer or the local hard drive in the first computer.

8. A computer system comprising one or more processors, one or more computer readable memories, and one or more computer readable storage mediums, and program instructions stored on at least one of the one or more storage mediums for execution by at least one of the one or more processors via at least one of the one or more memories, the stored program instructions comprising:
program instructions to detect a request from a first computer to store a data item;
program instructions to determine if a volatile memory in a second computer comports with an isolation rule for the data item, wherein the isolation rule prohibits sensitive data from two companies co-residing on the volatile memory, wherein comporting with the isolation rule permits the data item to be stored in the volatile memory in the second computer;
program instructions to, in response to determining that the volatile memory in the
