Redundant Infrastructure

How much of the cloud infrastructure is redundant?

Redundancy offers security in the sense that your applications will be there almost no matter what happens to you cloud provider's own infrastructure.

Most cloud providers offer to automatically protect your data by running independent and geographically distinct data centers, so that your infrastructure will continue running even if one of their data centers fails. It doesn't hurt to ask before you start using the service. Amazon, for example, has several distinct "zones" in North America, Asia, and Europe where its servers are located. A user can specify the location of his virtual servers and design an environment to be protected in case of any failures. A more complete discussion of the various security decisions involved in using Amazon's Web Services can be found here. For the US Golf Association, Carroll built in the requirement that the vendor provide a hot site at another location in case of any downtime. "We pay a bit more for this redundancy, but it gives us a level of comfort too."

Amazon's Web Services can provide for geographic diversity through its zones and regions in three different continents.

    Answer: It's safe IF you play your cards right, but almost all of the time you can forget about decent security

  • You haven't really addressed many of the security concerns IT pros have about "the cloud". Who potentially has access to my data, what controls are in place to keep that data safe (ie could a rouge employee rip backup of my DB and take it home)? How are other legal situations handled, such as warrants/requests for data from law enforcement, will the customer be notified, will the vendor simply comply, etc? What happens *IF* the cloud vendor goes out of business one day, where is my data (one would assume there would be warning signs before this happens, but stranger things have happened)? There are tons of questions with not many good answers out there.

    Check out this cloud-based (Software as a Service) platform and its security architecture.

    This article barely scratches the surface of security issues surrounding cloud computing. It reads more like an executive summary than something I would expect to see on Tomshardware - very disappointing.

  • Cloud computing is overrated. Your data will never be secure in someone else's hands. Any encryption can be broken with time.

  • I didn't really see any mention of on-site encryption in this article, only transport encryption. Also, who assures us that claims made regarding security are entirely true instead of being marketing word-play which seems so popular these days. Only when a cloud service publishes results done by a third party auditor that I trust will I use them.

    If you are in the external cloud with your company your data will be compromise.. I'm 100% sure of that... we look at this cloud stuff 8 years ago and came to that conclusion if you need to do it, do it inside your company not outside...

    Security is always a concern, but my main concern with the cloud is around someone else being responsible for up-time / availability. Those priorities rarely line up across multiple companies. While you may recover lost revenue through a breach in service level agreements, you can't recover customer perceptions and experiences in the same way.

    There's an updated version of the Ponemon Cloud Security Study available from the report's sponsor, Dome9: http://www.dome9.com/resources/ponemon-cloud-security-study.

    Incidentally, Dome9 offers free cloud security for an unlimited number of servers. You can check them out at http://www.dome9.com. Essentially, their value prop is the ability to close administrative ports on a remote cloud server and make access available on demand. This is important in the cloud where your servers operate outside your traditional network, and leaving ports open exposes them to hackers, brute force attacks, and exploits.
