Virtualisation, blade server technology and complex SAN systems have brought a lot of extra power, flexibility and redundancy to computing systems, but they also bring a whole new world of security issues. New ways for people to attack systems, to intercept data and to launch DOS and spam attacks against others.
Putting together a server cloud costs a fair amount of money, but it is not just a matter of getting the right hardware and some basic virtualisation systems. Significant amounts of time, expertise and experience are absolutely vital to ensure the smooth and secure operation of a commercial server cloud.
At BitCloud we started the whole process of putting together our systems with security as the primary focus. It was in fact the biggest cause of delays throughout the development process, we simply did not move past the development stage until we were completely happy with the security aspects involved.
We have numerous firewalls protecting the cloud from external attacks. We have firewalls that further protect each node in the cloud, and networking and software settings that monitor and protect each server instance within each node, both from external attacks as well as internal attacks.
We are confident that our cloud is as secure as any comparable commercial cloud in the world, and that the slight cost overhead of this enhanced security will be accepted by our customers.
