1. Executive Summary
Moving towards virtual infrastructure is a great choice by ACL Reality Company. The company is using so many different physical servers like directory domain control, database servers, email servers, file and print server, sharePoint server, CRM and Linux servers for effective management of services. But in place of all these servers, the ACL Reality Company can make use of virtual infrastructure. The IaaS services will be best suited for ACL Reality Company. In this clod service, the vender is responsible to maintain and develop all physical infrastructures and client organization like ACL Reality Company can use all services by making payment. The physical configuration of any infrastructure is not required at client organization. It is the best model which justifies the complete infrastructure requirements of ACL Reality Company. The IaaS model of cloud provides the infrastructure of applications and different servers to all client organization in minimum cost. The work load of maintaining all different servers and related applications is removed from ACL Reality Company. The internet services are being utilized for providing the services of IaaS to client organizations [Ren et al, 2017]. 
The maintenance of eight different physical servers is heavy, time consuming and costly process for ACL Reality Company. The company has to maintain a separate team just to handle all these required servers. But the development of virtual infrastructure can solve all these issues of setup and mainly maintenance for ACL Reality Company.
