Overview of this book

Most enterprises use Cisco networking equipment to design and implement their networks. However, some networks outperform networks in other enterprises in terms of performance and meeting new business demands, because they were designed with a visionary approach. The book starts by describing the various stages in the network lifecycle and covers the plan, build, and operate phases. It covers topics that will help network engineers capture requirements, choose the right technology, design and implement the network, and finally manage and operate the network. It divides the overall network into its constituents depending upon functionality, and describe the technologies used and the design considerations for each functional area. The areas covered include the campus wired network, wireless access network, WAN choices, datacenter technologies, and security technologies. It also discusses the need to identify business-critical applications on the network, and how to prioritize these applications by deploying QoS on the network. Each topic provides the technology choices, and the scenario, involved in choosing each technology, and provides configuration guidelines for configuring and implementing solutions in enterprise networks.

Functions of a data center

A DC is the core of the enterprise network. Most enterprise network communications have one end of the communications within the DC. This is because the DC hosts most of the enterprise applications that are accessed by a majority of the users. These applications could be core business applications, or business supporting applications such as email applications.

The DC also hosts the major databases within the organization. Most of the organizational data is stored in databases such as SQL, RDBMS, Oracle, and so on. These databases require large computing and storage resources and skills to manage and maintain the databases. Centralizing these databases helps to contain the operational costs of the organization.

If an organization deploys some IoT applications, the servers and the central processing of those applications also happens within the DC. Any...
