Abstract

Technologies are generally described for systems and methods effective to provide migration of data to a cloud computing service without interruption of service to client devices. In an example, a method includes establishing a first communication link with one or more communication devices and establishing a second communication link with a source device. The method also includes transferring via the second communication link at least a data set of a plurality of data sets of the source device and storing at least the data set to a data store. Further, the method includes receiving, via the first communication link, a request for the data set or another data set of the plurality of data sets, wherein the request is received from a communication device of the one or more communication devices.

Claims

1. A method, comprising:

facilitating, by a system comprising a processor, establishing a first communication link with one or more communication devices for replacement of a direct communication link between a source device and the one or more communication devices, wherein the source device comprises a plurality of data sets;

facilitating establishing a second communication link with the source device;

transferring, via the second communication link, at least a data set of the plurality of data sets;

storing at least the data set to a data store; and

receiving, via the first communication link, a request for the data set or another data set of the plurality of data sets, wherein the request is received from a communication device of the one or more communication devices.

2. The method of claim 1, further comprising:

using an identifier of the source device during a communication with the one or more communication devices; and

using one or more identifiers of the one or more communication devices during another communication with the source device.

3. The method of claim 1, further comprising processing the request, comprising:

accessing the data store for the data set; and

transmitting a reply to the request to the communication device, wherein the reply comprises at least a portion of the data set,

wherein the request is a read request for the data set.

4. The method of claim 1, further comprising processing the request, comprising:

determining the other data set is not contained in the data store;

simulating a functionality of the communication device;

receiving the other data set from the source device via the second communication link; and

transferring, via the first communication link, at least a portion of the other data set to the communication device in response to the request,

wherein the request is a read request for the other data set.

5. The method of claim 4, wherein the simulating comprises:

using an identifier of the communication device during a communication with the source device;

requesting the other data set from the source device; and

storing the other data set in the data store.

7. The method of claim 1, further comprising processing the request, comprising:

accessing the data set from the data store;

receiving the other data set from the source device; and

sending respective portions of the data set and the other data set to the communication device in response to the request.

8. The method of claim 1, wherein the facilitating the establishing of the first communication link comprises intercepting a communication from the communication device, wherein the communication from the communication device is identified based on an identifier associated with the source device.

9. The method of claim 1, further comprising:

monitoring write data received from the communication device;

storing the write data in the data store; and

distinguishing the write data from the data set and the other data set,

wherein the distinguishing comprises marking the write data as new data.

11. The method of claim 1, further comprising:

determining the plurality of data sets have been migrated from the source device; and

terminating the second communication link.

12. The method of claim 1, wherein the facilitating the establishing of the second communication link comprises facilitating establishing a client relationship with the source device that performs a background operation during a transfer of data sets from the source device.

13. The method of claim 1, wherein the facilitating the establishing of the second communication link comprises communicating with the source device via one or more intermediate network devices.

14. The method of claim 1, further comprising processing the request, comprising initiating replication of a network service that is transparent to the communication device.

15. A system, comprising:

a memory storing computer-executable components; and

a processor, communicatively coupled to the memory, which executes or facilitates execution of one or more of the computer-executable components, the computer-executable components comprising;

a client processing manager configured to establish a communication session with a device;

a background processing manager configured to establish a link with a host service, wherein the host service is configured to process requests from the device;

a data relocator configured to migrate data from the host service to the memory via the link;

a communicator configured to receive, via the communication session, a request from the device for a subset of the data; and

a service request processor configured to obtain the subset of the data from the memory or from the host service,

wherein the communicator is further configured to send the subset of the data to the device in response to the request, and

wherein the data relocator is further configured to migrate the data from the host service concurrently with the service request processor obtaining the subset of the data.

16. The system of claim 15, wherein the data relocator is further configured to determine the data from the host service has been migrated to the memory and the background processing manager is further configured to disable the link with the host service.

17. The system of claim 15, wherein the background processing manager is further configured to establish the link with the host service via an intermediate device, and wherein the intermediate device is a communication network device.

19. The system of claim 15, wherein the request is a read request and the service request processor is configured to search the memory for the subset of the data and mirror a functionality of the device to access the host service for data not found in the memory, and wherein the communicator is further configured to send the data accessed from the host service to the device.

20. The system of claim 15, wherein the client processing manager is further configured to intercept communications from the device, and wherein the communications comprise an address associated with the host service.

21. The system of claim 15, wherein the request comprises a write data segment stored in the memory, and the computer-executable components further comprise an overlay protector configured to identify the write data segment as non-rewritable data.

22. The system of claim 15, wherein the link with the host service is a client relationship with the host service, and wherein the host service is configured to perform background operations concurrently with migration of the data by the data relocator from the host service to the memory via the link.

23. The system of claim 15, wherein the service request processor is further configured to replicate a network service that is transparent to the device.
