A question that I’ve encountered many times in the field of late is what are the impacts of DDoS attacks on cloud compute environments? The primary benefit of cloud is that it elastically scales to meet variable demand, scale up instantly, scale down when demand subsides – in seconds… So layman’s logic might say that cloud-based services are immune from the downtime effects of DDoS attackers, however the possibility of gigantic unexpected bills is a given?
Recently, my computer failed and I had to get it fixed and my data restored. It took several days to identify the specific problem (in this case, catastrophic hard drive failure) and restore access to my applications and data. In the meantime, my productivity dropped dramatically and it was hard to work using the alternative tools that were available to me.
I live relatively close to Ashburn, Virginia, which you may know is a major exchange point for the Internet. Our area has gone through phases of development over the past 15-20 years that I’ve lived in there, starting with an explosion of residential development (which we can thank in large part for our notoriously bad traffic). But more recently I’ve noticed a shift in the development and construction within the region. Rarely does a week pass now where I don’t notice a new area being cleared for significant construction.
In enterprise environments it is common for an application to be hosted by a pool of servers, either physical or virtual. Over time these applications also go through a lifecycle that consists of security patches, maintenance, upgrades to update capabilities, and changes to keep up with trends such as virtualization, consolidation and deployment in a hybrid cloud environment. For scalability, additional servers may also be deployed.

There were a lot of promises made when software-defined networking (SDN) first came onto the scene, and while some real benefits have been experienced, not all promises have been realized, or were even realistic. Such is commonly the case with new technologies: the initial hype exceeds the reality of the situation, but usually there are reasons to hold firm to the trend and take advantage of what the technology does deliver successfully.
