Software-Defined Storage for Containers Ignores Storage

Software-defined storage (SDS) within the container realm often ignores storage itself. In essence, the SDS platform assumes some chunk of storage is mapped to a container host. Then, it takes over from there. SDS for containers is the orchestration through …

Virtual Networking Is Not Network Virtualization

While SPB is a very interesting protocol, my questions were about how deep into the virtual environment the protocol extends. While SPB and other networking protocols are considered by some to be network virtualization, I could not see this within the realm of the virtual network and hence, confusion reigned supreme. Depending on who is talking to each other, the same words can mean many different things. What I found amazing, still, is that most people thinks networking ends at the physical NIC within the virtualization host, and that what is inside, does not matter as much as what is outside.

Cloud Scale Apps, Cloud Scale Testing

While at Interop I participated in a Tech Field Day event where Spirent was talking about their new Axon product as well as the possibility of usage of Blitz.io. It was an interesting discussion but gave me some food for thought. As we move to cloud scale apps based on platforms such as Pivotal (EMC World was just down the street), OpenShift, and others, we need a way to test those applications at scale. Spirent and Ixia provide these tools, but would they be used in this new model.

Virtualization Field Day Delegates Discuss Cloud Security and Compliance

The Virtualization Field Day delegates joined the Virtualization Security Podcast as guest panelists on 2/23 and the topic of the day was cloud security. There were questions about compliance, security of the tenant, and security of the administrators, and legal issues. There were answers from Rodney Haywood (Rodos), another Virtualization Field Day Delegate and cloud architect as well as the podcast standard panelists. So what did the questions boil down to?

Fix the App or Add Hardware?

While participating in the GestaltIT Virtualization Field Day #2, I was asking PureStorage on whether or not SSD based storage was throwing hardware at a problem that is better fixed, by changing the code in question? What brought this thought to mind was the example used during the presentation which was about database performance. This example, tied to a current consulting problem, where fixing the database improved performance by 10x. This alleviated the need for over all storage improvements. So the question remains, is using SSD, throwing hardware to solve a basic coding problem?
