An object worker is instantiated at a compute server of a distributed cloud computing network, where the object worker includes a single instantiation of a piece of code that solely controls reading/writing to an object. An external communication policy is associated with the first object worker. If the external communication policy does not allow the object worker to send communications with the object to an asset that is external to the distributed cloud computing network, the communication is prevented from being sent. If the external communication policy allows the object worker to send communications with the object to the asset that is external to the distributed cloud computing network, the communication is sent from the first object worker to the asset.

State management and storage with policy enforcement in a distributed cloud computing network

A first compute server of a distributed cloud computing network executes an application that controls reading and writing access to associated persistent data. The first compute server performs a write operation to the persistent data on local storage, notifies a piece of code that controls outgoing messages from the application that the write operation is pending, and transmits write information for the write operation to a set of other compute servers. If an acknowledgement of the write information is received from a quorum of the other compute servers, the application notifies the piece of code that the write operation is confirmed. Periodically the write information is transmitted to an external storage system. If a confirmation that the write information has been written is received from the storage system, the first compute server transmits a write confirmation notice to the other compute servers, which can then delete the write information.

State management and persistent data storage in a distributed cloud computing network

A compute server of a distributed cloud computing network receives a request for an object that is to be handled by an object worker, where the object worker includes a single instantiation of a piece of code that solely controls reading/writing to the object. The object worker is instantiated at the compute server. The compute server enforces an access policy to determine whether the request is allowed to be processed by the object worker. If the request is allowed to be processed by the object worker, the object worker processes the request. If the request is not allowed to be processed by the object worker, the request is blocked.

Concurrency control in an asynchronous event-loop based program environment is described. A program is implemented with an asynchronous event-loop. A piece of code controls events into the program by preventing events from being delivered to the program while a storage operation is executing except for storage completion events. Those events are prevented from being delivered to the program until the storage operation completes and the program is not executing code.

A first piece of code controls events into the program by preventing events from being delivered to the program while a storage operation is executing except for storage completion events. Those events are prevented from being delivered to the program until the storage operation completes and the program is not executing code. A second piece of code controls outgoing messages from the program by preventing outgoing messages from being transmitted when a storage write operation is in progress except for outgoing messages that are storage write operations. Upon the successful completion of the storage write operation, the outgoing messages that were prevented from being transmitted are transmitted.

A compute server of a distributed cloud computing network receives a request for an object that is to be handled by an object worker, where the object worker includes a single instantiation of a piece of code that solely controls reading/writing to the object. Policies are accessed that are applicable for processing the object. If the policies do not allow the object worker to be instantiated on the compute server, the object worker will not be instantiated and the request will not be processed at that compute server. If the policies allow the object worker to be instantiated on the compute server, the object worker is instantiated and the request is processed.
