As enterprises grow in size, and enterprise applications become more critical to business operations, CIOs are faced with a design dilemma: should branch offi ce infrastructure be centralized or distributed?
In a distributed implementation, email servers, fi le servers and databases are placed locally within each branch location. While this typically provides the best possible performance to end users, it results in “server sprawl”, which can be costly to implement and creates a variety of management, security, and compliance challenges.

The centralization of branch offi ce servers and storage enables enterprises to more effectively manage and secure critical business information. By moving servers out of branch offi ces and consolidating IT infrastructure to fewer, purpose-built data centers, enterprises can protect vital business resources through tight physical security and well-defi ned access procedures. In addition, server centralization limits the amount of places where sensitive user credentials are stored, helping to ensure that this information remains protected from unauthorized access.

Enterprises have long been battling the inherent performance limitations of Wide Area Networks (WANs) when delivering applications to remote offi ces. Caching emerged in the 1990’s as a potential way of addressing this problem, accelerating the performance of specifi c applications, such as web services, while reducing overall WAN traffi c. While caching achieved reasonable success for a few short years, the market for these point products ultimately subsided as a result of several operational and functional limitations.

As companies become more reliant on business critical information, it becomes increasingly imperative to protect resources against unexpected loss. Threats come in many shapes and sizes – from server maintenance to unexpected network outages to catastrophic natural disasters that can debilitate an entire building or region. Significant emphasis is being placed on business continuity management as a way of addressing these concerns. As part of this process, CIOs are taking a hard look at their IT infrastructure to ensure that data is protected and easily recoverable in the event of an unfortunate event or disaster.
Data backup and replication are two solutions that are essential to most enterprises’ disaster recovery plans. However, given the fact that both of these solutions typically involve the transfer of large amounts of information across significant geographic distances, limitations in WAN technology can make it difficult to implement them effectively. By overcoming these challenges, Silver Peak’s WAN acceleration solution facilitates disaster recovery, making it an essential component of most enterprises’ business continuity plans.
