Receiving a data object at a device

1. A computer-implemented method, comprising:

receiving instructions to distribute a data object to a device, wherein the instructions indicate:

a messaging topic; and

a data block size receivable by the device;

dividing the data object into a set of data blocks corresponding to the data block size receivable by the device;

determining that the device is subscribed, via a subscription messaging service, to the messaging topic, wherein the messaging topic corresponds to the data block size;

sending, according to a network protocol established by the device, the set of data blocks to the device using the messaging topic; and

in response to receiving a message from the device indicating that a data block from the set of data blocks was not received, resending a missing block to the device.

2. The computer-implemented method of claim 1 , wherein:

the instructions further indicate a storage location; and

the computer-implemented method further comprises obtaining the data object from the storage location.

3. The computer-implemented method of claim 1 , wherein:

the instructions further indicate a deployment schedule; and

the computer-implemented method further comprises deploying the data object according to the deployment schedule.

4. The computer-implemented method of claim 1 , wherein the network protocol is Message Queue Telemetry Transport (MQTT) or MQTT for Sensor Networks (MQTT-SN).

5. The computer-implemented method of claim 1 , wherein:

the data object is associated with a signature;

the signature is based on the set of data blocks; and

sending the set of data blocks to the device further includes sending the signature.

6. The computer-implemented method of claim 1 , further comprising sending a second data object to the device, the second data object associated with a second messaging topic, the second messaging topic associated with a second data block size.

7. A system, comprising:

one or more processors; and

memory storing computer-executable instructions that, upon execution, cause the one or more processors to:

receive instructions to distribute a data object to a device, wherein the instructions indicate a data size receivable by the device;

divide the data object into data blocks corresponding to the data size receivable by the device;

determine that the device is subscribed, via a subscription messaging service, to a messaging topic, wherein the messaging topic corresponds to the data size; and

send the data blocks to the device using the messaging topic.

8. The system of claim 7 , wherein the computer-executable instructions are received from a job scheduling service in accordance with a delivery schedule for sending the data object to the device.

9. The system of claim 7 , wherein:

the computer-executable instructions further indicate a storage location; and

the system further includes obtaining the data object from the storage location.

10. The system of claim 7 , wherein the system individually encrypts the data blocks before sending.

11. The system of claim 10 , wherein Transport Layer Security (TLS) is used to encrypt the data blocks of the data object being sent using the TLS networking protocol.

12. The system of claim 7 , wherein the system encrypts the data object before dividing the data object into data blocks.

13. The system of claim 7 , wherein the system receives a completion notification from the device.

14. A non-transitory machine-readable storage medium storing executable instructions that, as a result of being executed by one or more processors of a computer system, cause the computer system to:

receive instructions to distribute a data object to a device, the instructions indicating:

a messaging topic; and

a block size receivable by the device;

divide the data object into blocks of the block size receivable by the device;

in accordance with a networking protocol established by the device, send the blocks to the device using the messaging topic, wherein the messaging topic corresponds to the block size; and

as a result of receiving a missing block message from the device, resend a missing block to the device.

15. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions further indicate a storage location from which the data object is obtainable.

16. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions further include deploying the data object according to a deployment schedule.

17. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions are received by a delivery service comprising a plurality of messaging topics.

18. The non-transitory machine-readable storage medium of claim 14 , wherein the instructions are based at least in part on delivery configuration data received at a data deployment manager service from a deployment setup client.

19. The non-transitory machine-readable storage medium of claim 14 , wherein a code signer service places a signature in at least one of the blocks of the data object.
