Instances widely provided by the public cloud provider services can be used or virtualized compute instances can be provisioned for hosting the application on private servers. In this project, we have used an AWS EC2 instance to set up the server side application on the instance for the client devices to communicate and transmit the messages. EC2 also provides additional security, and moreover, the compute capacity is easily resizable according to the demand.

Private servers can also be spun up if not going through with public cloud providers. The instances need to be spun up with updated hypervisors keeping scalability and durability in mind. Networking needs to be managed internally in that case and NAT gateways need to be set up to facilitate communication of the virtual instances through a public facing IP.
