Abstract: The disclosed technology teaches recovering a first virtual machine or an instance with an Internet Protocol address, a first root volume and one or more data volumes that are corrupted. The first virtual machine is hosted by a first cloud server that hosts plurality of virtual machines. The disclosed technology includes instructing the first cloud server to launch a recovery virtual machine. The recovery virtual machine launches one or more new data volumes based upon captured file system images in one or more snapshots taken of corrupted data volumes of the first virtual machine prior to becoming corrupted. The recovery virtual machine detaches the corrupted data volumes and attaches the new data volumes launched to the first virtual machine.

Abstract: Methods, apparatus, systems and articles of manufacture for communicating encrypted data via a virtual private network are disclosed. An example computer system disclosed herein includes a memory including instructions that, when executed, cause one or more processors to establish a first tunnel and a second tunnel between a VPN client and a VPN server. The instructions further cause the one or more processors to access a request message to be sent via the VPN and determine, in response to a payload being formatted using a first protocol, whether a packet associated with the request message includes an encrypted server name indication (SNI). The instructions further cause the one or more processors to, in response to the packet including the encrypted SNI, encrypt the header of the request message to form an encrypted header, create an encrypted message including the encrypted header and the payload of the request message, and transmit the encrypted message through the first tunnel.
