Overview

Understand Data Center network design and infrastructure architecture, including load balancing, SSL, and security Thorough coverage of Data Centers prepares networking professionals for design, architecture, and implementation challenges Design guidelines demonstrate how to successfully deploy server farms in highly available and highly scalable environments Examination of common challenges in architecting server farms helps reduce complexity and increase flexibility and predictability in design and deployment Learn to properly plan site performance capacity through detailed discussion of the Cisco server-farm architectures and their real-life applications Solid reference on core technology and design issues surrounding Data Centers Learn to incorporate security measures into your Data Center design and infrastructure Data Center Fundamentals addresses the principles and concepts a network specialist needs to understand to take on the most common challenges encountered during planning, designing, implementing, and managing Internet and intranet IP-based server farms. Data Center Fundamentals helps network operators, network engineers, and design engineers understand the fundamental concepts behind the design and scaling of web-hosting, e-commerce, and, in general, IP-based server farms using the Cisco Systems Data Center technologies. You gain an introduction to server-farm technologies, including overviews of Data Centers, applications and servers, Data Center security, and server load balancing. Part II covers fundamental technologies and protocols currently used in the Data Center, including IP, TCP, UDP, HTTP, DNS, and SSL and TLS. This part also includes chapter-length coverage of streaming protocols. From there, you learn about Layer 2 design, Layer 3 design, and IBM Data Center technology. Security services and server load balancing fundamentals are covered in detail, including session persistence and cookies, server health, modes and predictors, and multitier architectures. Putting it all together are chapters on Data Center design that also advise you on integrating security into your design and understanding performance metrics of Data Center devices. An in-depth analysis of the Data Center technology coupled with real-life scenarios make Data Center Fundamentals an ideal reference for understanding, planning, and designing scalable, highly available, and secure server farms applicable to web-hosting and e-commerce environments amongst others.
