It is interesting to note that even as vendors introduce new product lines, the legacy three-tier architecture remains as<br />
the reference architecture for <strong>Data</strong> <strong>Center</strong>s. This legacy three-tier architecture retains the same limitations in terms of<br />
scalability and increased complexity.<br />
Additionally, migrating to a new product line, even with an incumbent vendor, may require adopting a new OS,<br />
modifying configurations, and replacing hardware. The potential operational impact of introducing new hardware<br />
is a key consideration for insertion into an existing data center infrastructure, regardless of the platform provider.<br />
Prior to specific implementation at any layer of the network, it is sound practice to test interoperability and feature<br />
consistency in terms of availability and implementation. When considering an incumbent vendor with a new platform,<br />
any Enterprise organization weighing migration to a new platform from their existing one, should also evaluate moving<br />
towards a simpler high performing <strong>Juniper</strong>-based solution, which can deliver substantial incremental benefits. (See<br />
Chapter 3: <strong>Data</strong> <strong>Center</strong> <strong>Migration</strong>—Trigger Events and Deployment Processes for more details about introducing a<br />
second switching infrastructure vendor into an existing single vendor network.)<br />
In summary, migrating to a simpler data center design enables an enterprise to improve the end user experience and<br />
scale without complexity, while also driving down operational costs.<br />
