serious architecture contender. Obviously, another issue with centralized
deployments is that you’re effectively “placing all your eggs in one basket,”
thus placing demands on your business continuity planning. Business conti-
nuity planning should detail the plan to continue operations in the shortest
available time when a disaster strikes and the primary server farm cannot be
quickly brought back online. Data center fires are not unheard of, and other
natural and manmade disasters are also possible. If you must be able to con-
tinue operations in these exceptional circumstances, you must plan for a
disaster recovery environment in another datacenter.
The second option is to deploy regional instances in the user population
centers across the enterprise. While technically this is an easy fix, it does
cause headaches for the knowledge management and information architec-
ture planners. By distributing sites across servers, you are effectively creating
information silos in these regional environments. Operations overhead is also
increased, because there are now more servers to look over. The cost is likely
higher, given the extra hardware and operational requirements, especially if
high availability is still a requirement in these regional instances.
While regionalized deployments will continue to be a valid option, the
recent industry drive for datacenter consolidation is likely to ensure that cen-
tralized deployments will be the flavor for SharePoint 2007. For example, the
internal HP deployment for SharePoint 2003 spanned 6 farms across all
regions in an effort to balance network performance with centralized opera-
tions model. The deployment architecture was largely driven by the network
topology and designed to allow best possible end-user performance in the
company’s network framework. However, with the new drive for data center
consolidation, the architecture was collapsed to a centralized deployment in
SharePoint 2007. Given the new drive, the program was able to dictate the
required network topology that would support SharePoint deployment,
instead of the other way around back in 2003.
10.7 Preparing for Software Deployment
Before installing the products, you should take a moment to review some
upfront tasks that will help streamline the deployment process and save you
time and effort. Because certain infrastructure configuration changes, such as
adding DNS aliases and pointers, can take a while to synchronize across the
organization, it’s good to plan and execute them in advance.
10.7.1 Service Accounts
Service accounts are straightforward domain user identities. However, to
reduce operational overhead, they are often configured with different security
policies than normal user accounts. Typically, service accounts are set to
