Caching your Application, OS, or Storage

There is a new set of tools available for Caching up and down the stack which we covered within Caching through out the Stack, however in reality where is the best place to cache data for your application and what are the ramifications of using such a cache. Recently, we had a caching problem, actually two of them. Both caused by the same thing, a lack of full understanding about what was being cached. For any application, the best way to cache is to cache in memory as close to the application stack as possible, which in our stack could be within the application, the OS, or even a hypervisor based disk cache. However, which does your application actually use?

The Pros and Cons of Private and Public PaaS

I just returned from attending the Cloud Expo in New York City this week. The conference was dominated by private and hybrid cloud topics. There were several private Platform as a Service (PaaS) vendors attending whom I spent a great deal of time talking to as I walked the floor. It seems these days that many enterprises default to private and hybrid clouds and therefore insist on private PaaS as well. It is critical that consumers of PaaS services understand the pros and cons of both public and private PaaS before making a commitment to a PaaS deployment model.

Client Hypervisors: Intelligent Desktop Virtualization too clever for its own good?

In 2011, we asked if Client Hypervisors will drive will the Next Generation Desktop. Yet, other desktop virtualization industry experts, such as Ron Oglesby, decided the technology was a dead man walking, writing off Type 1 Client Hypervisors.

Are you using or considering implementation of a storage hypervisor?

Depending upon what your or somebody else’s definition of a storage hypervisor is, you may or may not be using one or realize it.

If your view of a storage hypervisor is a storage IO optimization technology to address performance and other issues with virtual machines (VMs) and their hypervisors, such as Virsto or ScaleIO along with others, you might be calling those storage hypervisors as opposed to middleware, management tools, drivers, plug-in, shims, accelerators, or optimizers.

Why You Should Invest in ASaaS, not PaaS

In addition to PaaS there is a class of vendors who provide external services to PaaS through “marketplaces” that the vendor sets up. We refer to these generically as Application Services as a Service (ASaaS). The stakes are potentially huge – the PaaS takes over from the Operating System as the dominant factor in the purchasing decision for server-side technology. We’re not saying it definitely will happen, but it might.
