Data Center Servers are Critical For Business Continuity

Business Continuity and Data Center’s issues

Business transactions delivered from the data center pose major challenges to business continuity.

Data center infrastructure and the networks that support it play a prominent role in automating business processes and communication across the organization, customers, partners, suppliers and regulators to ensure the organization continues to run during a disaster. Connectivity in data center infrastructure and the networks can be adversely affected by bottlenecks or complete failure due to network outages, hardware failures, human error and natural disasters.

Data center servers are vital corporate assets and keep the network up and running. Below are five areas that CIOs need to look for to create a reliable application delivery infrastructure for business continuity planning:

  • Server load balancing  – Server load balancing ensures application availability, facilitates tighter application integration, and intelligently and adaptively load balances user traffic based on a suite of application metrics and health checks. It also load balances IPS/IDS devices and composite IP-based applications, and distributes HTTP(S) traffic based on headers and SSL certificate fields.
  • Link load balancing – Link load balancing addresses WAN reliability by directing traffic to the best performing links. Should one link become inaccessible due to a bottleneck or outage, the ADC takes that link out of service, automatically directing traffic to other functioning links.
  • Global server load balancing – Geographical load balancing provides reliability between geographically dispersed data centers. ADCs redirect traffic to the best performing sites based on latency, site performance and user location. Global load balancing delivers high availability; if one site goes down, traffic will automatically redirect to other working sites.
  • SSL acceleration  – The National Institute of Standards and Technology (NIST) has mandated that businesses transition from 1028-bit SSL encryption to the more secure 2048-bit standard. Tests indicate that 2048-bit SSL encryption is 500 percent more resource intensive than 128-bit encryption. The result is that existing infrastructure will likely become bogged down supporting the new standard, impacting availability and the user experience for critical business processes.
  • TCP acceleration – With the rise of BYOD mobile traffic is increasingly outpacing traditional network traffic. Mobile traffic also uses far more connections and opens and closes connections far more often than traditional network traffic. Over time, legacy data center equipment will be unable to keep pace and application availability will suffer.

CIOs need to ensure the availability, performance and security of applications, servers and other devices within the data center, to validating reliable connectivity to global networks, to ensuring the availability of business processes under worst-case scenarios, application delivery controllers can for an organization’s business continuity plan.

Whether deployed in traditional data centers or in public or private clouds, modern application delivery controllers provide the features and performance needed to ensure business continuity while at the same time improving efficiencies, supporting next-generation standards and preparing organizations for growing trends in the areas of mobile and cloud computing.
