Getting to OpenStack

CloudComputingIn the industry, OpenStack is seen as very hard to implement. Considering this, I began to think that most people who deploy OpenStack try to bite off too a large chunk of OpenStack at one go, to implement it all instead of just what they need. OpenStack is a cloud management platform, not the hypervisor, so perhaps we can take some lessons from how we installed VMware products when we just started out. We still implement things using the same patterns for vSphere. We should revisit OpenStack with this history in mind.

VMware, Microsoft, Citrix, and Red Hat Cost Comparison

In part one of Cost to Build a New Virtualized Data Center, we discussed the basic software costs for a virtualized data center based on VMware vSphere 6.0, Citrix XenServer 6.5, Microsoft Hyper-V 2012 R2 and 2016, and Red Hat. If you missed that, please click here to review before continuing.

This post will take that original premise and expand it to include storage with a view to moving the entire environment toward a software-defined data center.

Over the last couple of weeks, I have been thinking about costs relating to a building a new virtualization-based data center. “What?” I hear you say. “Everywhere is virtualized—there is no such thing as a greenfield site anymore!” I would have said that myself, but in the last month I have come across three, one of which is a company worth over a billion pounds.

Choices We Have Plenty: Your Guide to Virtual Switches

DataCenterVirtualizationI was tinkering around with XenServer the other day. I know I can hear you saying “is that a thing?” Well, it is, but this is not what I am going to talk about today. Time for a tangent shift. I thought I would have a look for a third-party switch for XenServer, but it seems that XenServer is a third-rate citizen in this space, as there is no Cisco Nexus 1kV available for XenServer, even though Cisco previewed it at Citrix Synergy Barcelona in 2012.

Public Cloud Computing – Economics and Throats to Choke

CloudComputingWhen enterprises consider putting business-critical workloads in public clouds, many of them overlook, at least in part, critical issues of economics and over what portion of their cloud software stack the cloud vendor has full control. This leads to a situation where sometimes relatively inexpensive offerings where the vendor has full control of their software stack (like Amazon EC2) are improperly compared to an offering from a vendor like Savvis or Terramark who is building a cloud out of either VMware-provided components or OpenStack components. This gives rise to important issues that drive both the cost of the respective offerings and the degree to which the cloud vendor can both enhance the offerings with rapid agility and quickly address service level issues.
