Today's market demands that businesses have an Internet presence
through which they can perform e-commerce and customer support, and
establish a presence that can attract and increase their customer
base. Underestimated hit ratios, compromised credit card records,
perceived slow Web site access, or the infamous "Object Not Found"
alerts make the difference between a successful online presence and
one that is bound to fail. http://www.dropshippers.co.za/
These challenges can be solved in part with the use of data
center technology. Data centers switch traffic based on information
at the Network, Transport, or Application layers. Content switches
perform the "best server" selection process to direct users'
requests for a specific service to a server in a server farm. The
best server selection process takes into account both server load
and availability, and the existence and consistency of the
requested content. http://www.dropshippers.co.za/
Data Center Fundamentals helps you understand the basic
concepts behind the design and scaling of server farms using data
center and content switching technologies. It addresses the
principles and concepts needed to take on the most common
challenges encountered during planning, implementing, and managing
Internet and intranet IP-based server farms. An in-depth analysis
of the data center technology with real-life scenarios make
Data Center Fundamentals an ideal reference for
understanding, planning, and designing Web hosting and e-commerce
environments. http://www.dropshippers.co.za/
