(see p0050-p0063) and the client node includes parameter information that verifying party determination. (see p0084) request instantiation of a second container of the virtualized environment, wherein one or more configuration parameters of the second container are based on the set of container configuration parameters associated with the first container; Ozawa deploys a second processing is executed by a second processing deployed to a container platform of the origination C. (see p0050-p0070) and the client node includes parameter information that verifying party determination. (see p0084) configure the second container based on the set of node configuration parameters; and modify a network interface of the virtualized environment, which is associated with the first container, to be associated with the second container in lieu of the first container, wherein the second container communicates with one or more of the other nodes of the plurality of nodes via the network interface to maintain the distributed ledger. Ozawa p0050-p0070; p0144-p0186; Claim 2 The device of claim 1, wherein the network interface is associated with a particular external Internet Protocol ("IP") address when associated with the first container, wherein the network interface continues to be associated with the same particular IP address after being associated with the second container. Ozawa p0155, p0168; Claim 4 The device of claim 1, wherein the set of node configuration parameters include IP addresses of the one or more other nodes of the plurality of nodes. Ozawa p0155, p0168; Claim 5 The device of claim 1, wherein the container configuration parameters include at least one of: a storage resource parameter, a processor resource parameter, or a memory resource parameter. Ozawa p0155, p0168; Claim 6 The device of claim 1, wherein the first container includes a first operating system, and wherein the second container includes a second operating system. Ozawa p0068-p0078; As per claims 8-9 and 11-13, they are rejected under the same rationale as claims 1-2 and 4-6. See rejection above. As per claims 15-16 and 18-20, they are rejected under the same rationale as claims 1-2 and 4-6. See rejection above.

Ozawa p0008-p0016; Chandrashekhar p0060; It would have been obvious at the time of the invention for a person ordinary skill in the art (POSITA) to include Chandrashekhar’s teaching with method of Ozawa in order provide user with ability to function in an AWS private cloud network. As per claims 10 and 17, they are rejected under the same rationale as claim 3. See rejection above. Claims 7 and 20 are rejected under 35 U.S.C. 103 as being unpatentable over Ozawa US Publication 2020/0379982 in view of Gasperowiez US Publication 2022/0121466. 18/447,599 Ozawa US Publication 2020/0379982 in view of Gasperowiez US Publication 2022/0121466 Claim 7 The device of claim 6, wherein requesting instantiation of the second container is based on receiving an indication, from the virtualized environment, that the first operating system should be replaced with the second operating system. Ozawa p0008-p0016; Gasperowiez p0188; It would have been obvious at the time of the invention for a person ordinary skill in the art (POSITA) to include Gasperowiez’s teaching with method of Ozawa in order provide user with ability replaces container as back up.. As per claim 14, it is rejected under the same rationale as claim 7. See rejection above.
