Network Edge Traffic Steering: IP Services
FIGURE 1-6 shows an overview of the various IP services that can be used in creating a multi-tier data center network architecture. These services are essentially packet processing functions that alter the flow of traffic from client to server for increasing certain aspects of the architecture. Firewalls and Secure Sockets Layer (SSL) are added for increasing security. Server load balancing (SLB) is used to increase availability, scalability, flexibility, and performance. In Chapter 4, we describe key services that the architect can leverage, including in-depth explanations of how they work and which variant is the best and why. A question that is often asked is which server load balancing algorithm ...
