Challenges of Software as a Service
The adoption rate of Software as a Service (SaaS) has been dramatic in recent years. Trials of applications like Salesforce. com, WebEx, or NetSuite have transitioned to enterprise-wide deployments, and many organizations have adopted “SaaS first” policies.
However SaaS adoption is not without its challenges. The tendency of SaaS applications to be siloed has made managing user access and authorization an increasing challenge. The task of on boarding users is a time-intensive, manual process that involves administrators across multiple departments, which can introduce risk. Users hate having multiple passwords. Help desks hate multiple passwords too, since users forget them. Managing and synchronizing multiple passwords is expensive and problematic. IT departments must find a way to harness the benefits of SaaS, while minimizing business risk.
Microsoft System Center is a set of server products aimed specifically at helping corporate IT administrators manage a network of Windows Server and client desktop systems.

Distributed File System (DFS) is a set of client and server services that allow an organization using Microsoft Windows servers to organize many distributed SMB file shares into a distributed file system. DFS provides location transparency and redundancy to improve data availability in the face of failure or heavy load by allowing shares in multiple different locations to be logically grouped under one folder, or DFS root.
A distributed file system is a client/server-based application that allows clients to access and process data stored on the server as if it were on their own computer. When a user accesses a file on the server, the server sends the user a copy of the file, which is cached on the user’s computer while the data is being processed and is then returned to the server.
Ideally, a distributed file system organizes file and directory services of individual servers into a global directory in such a way that remote data access is not location-specific but is identical from any client. All files are accessible to all users of the global file system and organization is hierarchical and directory-based.
