Chapter 5: Internet Performance in the Eyes of Your Business 37 These materials are © 2015 John Wiley & Sons, Inc. Any dissemination, distribution, or unauthorized use is strictly prohibited. Protect Your Brand Poor Internet Performance can result not only in lost revenue but also damage to your brand. Online customers expect busi- ness websites to always be reachable, fast, and secure (see Chapter 4). A major component of Internet Performance is business con- tinuity planning. Business continuity planning is closely related to disaster recovery planning, but is specifically focused on what your company will do to keep the business running in the event of an outage or disaster. Disaster recovery planning focuses on the steps necessary to restore the business to its normal operating condition. Business continuity planning often begins with a business impact analysis (BIA) to determine what effect the loss of spe- cific systems and applications will have on your business. A BIA helps you prioritize your business continuity efforts and identify potential dependencies among systems, applications, data centers, networks, and service providers that need to be addressed in your business continuity plan. Key elements of an effective business continuity plan must address the following: ✓ Third‐party dependencies: Ensure that the partners you rely on have developed plans of their own to ensure your business can operate after an event or disaster. ✓ Active failover: You can automatically reroute your Internet traffic to another fully operational data center and minimize or eliminate the business impact of an event or disaster. ✓ Redundant services: Eliminate or mitigate single points of failure throughout your infrastructure. For example, DNS services should not be located in the same data cen- ters or hosted by the same cloud providers as your appli- cations in order to ensure you can route Internet traffic around outages.
