Cloud Talk Debrief: Impromptu Session

by dave on February 17, 2009

Yesterday, I held a rather impromptu “Cloud Talk” session with some of the Twitter community that has expressed an interested in cloud computing, cloud storage, etc.  I’m happy to report that given the rather abrupt beginning of the session, I still was able to sit down and talk with seven individuals (sorry, Stu 😉 ) that had some interesting thoughts and ideas about what the cloud is and isn’t.

The common theme that was discussed (suprisingly) was about the role of what I’ve deemed “middleware;” that is, the specific “connectors” that tie an internal set of applications and their data, processing, security capabilities to one or more cloud services like GoGrid, Nirvanix, Mosso, and S3. This would also be know as “PaaS” (Platform as a Service) or “IaaS” (Infrastructure as a Service).  Admittedly, everyone has their own spin on this and the overall taxonomy for the cloud is really still under development by all parties, but the general consensus was tied to this absolutely crucial connection piece.

Private Clouds & Storage: Considerations

by dave on February 13, 2009

One of the current “hot” topics within the IT industry these days is the concept of cloud computing.  While there is a level of ambiguity around what cloud computing actually is, there is a definite trend towards looking at what these cloud services and storage can do for the commercial and enterprise.

Private Cloud Challenges

In a previous posting, I talked about the concept of a common cloud file system or cFS.  Some folks responded on Twitter that perhaps IBM‘s GPFS filesystem (as a part of their SOFS strategy) could indeed fulfill that role for the cloud.  As an additional twist, PaaS “connectors” such as SnapLogic, et. al. that seek to tie front-end processes or applications to underlying cloud services could simply provide a API hook to entities like Nirvanix, GoGrid, Amazon S3, etc. for handling discrete storage functions (with the obvious implications of data access/protection SLAs being separate and distinct from the middleware providers).  The provision for this changes when you start talking about privatizing the cloud.

Shared Filesystems in the Cloud

by dave on February 11, 2009

Earlier this morning, Scott Lowe posed the following question:  What if hypervisors shared a file system? The concept here is that most hypervisors (notably VMware and [soon] Hyper-V) have a clustered file system that is used to extend the capabilities of a group of hypervisors into such things as dynamic resource sharing, failover/failback, HA, etc.  The natural extention of this, when looked at from a longitudinal viewpoint, is extending the same basic model into the cloud.
