Improving Bandwidth Utilization
Point No. 5: Improving bandwidth utilization
Treating recreational, mission-critical, and non-business traffic with equal priority causes many problems. It can bring networks down, provide an unfair advantage to a few users and applications, allow traffic peaks that consume all available bandwidth, and cripple productivity for all.IT should control, filter and rate different types of traffic on the network: time-sensitive traffic [voice over IP (VOIP), multimedia, streaming, and video conferencing], best effort (Web, instant messaging, and FTP), and unwanted (non-corporate and peer to peer). Prioritizing and classifying application traffic based on protocol, port or Layer 7-based information optimizes networks for delivering core business applications, improves response times, and improves bandwidth utilization and ROI.
Point No. 6: Implementing best practice security methods
Organizations benefit from Secure Sockets Layer (SSL) security, but high volumes of SSL traffic drag down even the most powerful, general-purpose Web server hardware. To comply with regulations [such as the Health Insurance Portability and Accountability Act (HIPAA), the Sarbanes-Oxley Act, or the Payment Card Industry Data Security Standard (PCI DSS)] or to comply with liability or self-imposed requirements for securing application services, IT can take advantage of hardware-based SSL offloading. Hardware SSL acceleration offloads and secures mission-critical applications, removes tradeoffs between security and acceleration, and increases trust of online users.
In addition to application intrusion attacks, DDoS (distributed denial of service) attacks are back and bigger than before. Network latency and packet loss increase with DDoS attacks, forcing applications to slow to a crawl. Networks become congested, and packet loss and latency increase. Integrating ADCs with DDoS protection capabilities protects networks, servers, and applications, in addition to improving Website, application, and server performance. This results in happy customers, increased business productivity, and reduced IT expenses.
Point No. 7: Resource consolidation and ROI
Older-generation data centers use separate devices for server load balancing, SSL offloading, caching, compression, DDoS protection, and firewalling of Layer 4-7 applications. On an aggregate, these devices would consume 1,000 or more watts annually. But by using integrated ADCs, IT can reduce hardware footprint, rack, power and cooling costs.
