We often hear from companies with cloud applications that ensuring the availability of critical web-based services and applications is a key requirement for enhancing user experience and engagement. After all, customers often leave company websites if they have to wait for them to load, which could result in lost revenue and brand value — all because of something that could be easily avoided.
As businesses continue to move critical operations online, distributed denial of service (DDoS) attacks are increasing in frequency, sophistication and range of targets. In a 2011 Verisign study, 63 percent of respondents reported experiencing at least one attack that year, while 51 percent reported revenue loss as a result of downtime from the attack. Those numbers are undoubtedly higher today as the size, frequency and complexity of DDoS attacks continue to grow. Mitigation against these types of attacks is challenging and generally requires layered solutions across data centers and the cloud management. The success of these attacks and their ability to damage a company’s infrastructure, revenue and reputation is indicative that many IT managers still haven’t found the right protection formula to proactively mitigate them.
