Introduction
Bluesky Systems is a software development company that builds software components for a variety of private and government clients. Their current infrastructure is outdated and has been prone to being attacked by hackers that have exploited vulnerabilities in their current DNS causing serious down time. In the last 4 years Bluesky has had to recover from numerous disasters due to a lack of any good business continuity planning. Remote access to the two existing sites is allowed using Cisco VPN technology. This has caused numerous security issues because of missing security patches, outdated AV signatures and missing OS patches and updates.
Bluesky currently has 45 employees in their Tucson location and 15 in their Phoenix location. Bluesky is preparing to add another remote site in Sierra Vista to support their military contracts scheduled to be awarded in 2014. The Sierra Vista location will add another 12 employees to the network. Bluesky needs to bring their current infrastructure into strict compliance with government security as a trusted network with access to government data. Bluesky Systems needs to upgrade their current infrastructure of Windows Server 2003 to Windows Server 2008. The move is designed to improve over all server performance, security, application and data provisioning, monitoring, and business continuity. This is will also begin the process of bringing Bluesky into compliance as a trusted government network. Executive Summary - Provide a high level executive summary of your Infrastructure proposal. Imagine that you have 20 minutes to present your proposal to the board of directors. Explain to the board the issues with their current infrastructure; highlight the key aspects of your design and how your proposal will benefit Bluesky Systems. Close out your executive summary by summarizing why Bluesky should select your proposal and not your competitors'. Assume that the board of directors is not technical. Be careful of the technical jargon you use. This is your one chance to shine before the executive committee and convince them that you are the right chose for their network up grade. Be persuasive!
