Rick is the IT administrator of a small organization, which has a single central server for all the internal service requests of the employees. Due to the recent increase in the team size, the server has been overburdened leading to delays in the processing of employees' requests. Since cost is an issue, the organization does not want to add more servers and is not willing to go for virtual servers outside the facility. To solve the problem, Rick interconnected the individual computers of the team members and took the server out of the process. This balanced the load between all the computers bringing down the processing time. Which architecture did Rick use in this scenario?
