FIGHT-THROUGH NODES WITH DISPOSABLE VIRTUAL MACHINES AND ROLLBACK OF PERSISTENT STATE |
摘要 |
A server system receives messages from client computing devices. Each of the messages corresponds to a transaction. The server system assigns each respective transaction to a respective fresh virtual machine. Furthermore, the server system performs, as part of a respective virtual machine processing a respective transaction, a modification associated with the respective transaction to a shared database. The shared database is persisted independently of the plurality of virtual machines. In response to determining that processing of the respective transaction is complete, the server system discards the respective virtual machine. In response to a trigger, such as determining that the respective transaction is associated with a cyber-attack, the server system uses checkpoint data associated with the respective transaction to roll back the modifications associated with the respective transaction to the shared database. |

1. A method comprising:
initializing, by a computing system and from one or more common templates, a virtual machine that executes on one or more computing devices of the computing system; responsive to an occurrence of an initiation condition of a transaction, assigning, by the computing system, the transaction to the virtual machine; generating, by the virtual machine, as part of the virtual machine processing the transaction, a database modification request associated with the transaction; responsive to the database modification request associated with the transaction, performing a modification to a shared database that is persisted independently of the virtual machine; generating checkpoint data associated with the transaction; responsive to a trigger, discarding, by the computing system, the virtual machine; and responsive to a rollback request, using the checkpoint data associated with the transaction to roll back the modification to the shared database performed responsive to the database modification request associated with the transaction. |
