And about this, you perceptively ...And the rest...<br /><br />And about this, you perceptively note:<br /><br />“Basically, they would rather own a version of the Amazon EC2 than use it, solely for reasons of governance.”<br /><br />But that is specifically because they have control over the governance issues with a private cloud (which can include the use of public clouds via things like cloud-bursting -- When & Where it is appropriate and is within policy), and yet have no way to do it (at least not currently) with public clouds.<br /><br />And very specifically, the answer (at least right now) is “No” to your question:<br /><br />“Couldn’t companies impose their governance and security requirements on third-party infrastructure, using company-owned governance tools and approaches to manage remote services? Couldn’t we simply demand that the public clouds provide greater governance and security control?”<br /><br />Lastly, I'll also note that some people from UCSD & MIT just figured out how to break down a lot of the supposed security between virtual containers in Amazon’s EC2 (the paper is posted here: http://people.csail.mit.edu/tromer/papers/cloudsec.pdf).<br /><br />-PhilDana Gardnerhttps://www.blogger.com/profile/05634998093031533262noreply@blogger.comtag:blogger.com,1999:blog-1479220138877439816.post-28612968975242925592009-10-01T20:27:47.000-04:002009-10-01T20:27:47.000-04:00Ronald,
Interesting article, but allow me to com...Ronald, <br /><br />Interesting article, but allow me to comment and bring a couple of points to bear that haven't been considered.<br /><br />First, let's look at this from a medium to large IT shop's perspective: A key point is why would I rent a public resource when I own the same privately. Normally this comes down to two reasons, highly variable needs or scale that provides lower costs than can be achieved internally. For most enterprise apps, they don’t have highly variable needs and most Fortune 2000 customers will find the excess capacity in their existing data center to be MUCH cheaper than a public cloud such as EC2. They have huge investments in virtualization and equipment already in place, so it makes more sense to add governance and management on top of that instead of trying to solve all of the listed problems and push it out to the public cloud (from one of the articles that you point to from your previous writings about cloud computing):<br /><br />“Cloud availability. Cloud security. Erosion of data integrity. Data replication and consistency issues. Potential loss of privacy. Lack of auditing and logging visibility. Potential for regulatory violations. Application sprawl & dependencies. Inappropriate usage of Services. Difficulty in managing intra-Cloud, inter-Cloud, and Cloud and non-Cloud interactions and resources. And that’s just the short list.”<br /><br />Excellent list! You then note how this can all be controlled by governance similar to what customers should have been doing with SOA (but few ever really achieved) without noting just how difficult it will be due to the fact of the lack of transparency that public cloud providers shroud everything in because it is their “secret sauce”. This could well change in the future, but right now it is nearly impossible to get all of the details needed from Amazon, Rackspace, etc in order to create appropriate governance rules and policies.<br /><br />The beauty of policy based private cloud management is that it can take all of these factors into account, help the customer decide on resource and workload allocation strategies, how/when cloud bursting can be used (i.e. which applications are allowed or not, if/when data must go over the wire encrypted, data wiping afterwards, short time based storage only, relevance to audit trails, etc etc), in addition to utilizing heterogeneous resources to reduce CAPEX while driving extra efficiencies by homogenizing during technical refreshes, and much more. <br /><br />More to come...<br /><br />Phil Morris<br />CTO, HPC BU<br />Platform Computing<br /><br />-PhilDana Gardnerhttps://www.blogger.com/profile/05634998093031533262noreply@blogger.com
