For an IT department these are perilous times indeed. All around you public cloud vendors are offering IT services on an easy to procure, elastic and often inexpensive basis. Many of the developers in your organization may have already concluded that getting resources provisioned for development and test projects is easier at Amazon.com than it is through your internally offered processes. If you are aware that this is happening you can console yourself by saying, “it is only development – not production”, but you should wonder what should you do to make sure that those workloads come back when they do go into production.

DRS is one of the most useful and interesting features of VMware vSphere (to be more specific – feature of versions of vSphere from Enterprise on up). DRS is useful because it prevents workloads (VM’s) that are consuming more than the expected amount of resources, from potentially harming the performance of their neighbors in the same host with this “excess” resource consumption. DRS is interesting because the idea of dynamically balancing the load of a system in order to ensure the performance of the critical workloads running on that system is something that was taken for granted in the days of the mainframe, but has not as yet been well implemented on distributed Intel architecture systems. Continue reading Replacing DRS – With What and Why?
One of the key themes of VMworld 2010 was “IT as a Service”. IT as a Service is simply the next logical step beyond virtualization. The key parts of the evolution from virtualization to IT as a Service is that IT as a Service involves a self-service aspect where business constituents can select “services” that are then automatically provisioned and delivered to them, and the notion of secure multi-tenancy within an enterprise’s data center for the purpose of separating the environments of multiple business units, departments or divisions much in the same way that a public cloud vendor must separate the environments of Coke and Pepsi. Continue reading Is VMware vCloud Director an effective Enterprise IT as a Service Platform?
In VMware and the Ionix Assets – A Deeper Look, we took a fairly in depth look at the four products that VMware bought from EMC, and posited that VMware was now well on its way to fulfilling its promised intentions of becoming a vendor of a management stack for virtualization. In this article we take a look at the impact of these acquisitions upon the virtualization management market and the ecosystem of solutions available in this market.

As virtualization matures, great progress is being made towards the goal of allowing performance sensitive applications to run on virtualized platforms. The performance and scalability gains delivered by VMware vSphere are a huge step in this direction. Other good steps in this direction are:
- vApp from VMware which allows a multi-server application to be encapsulated in one OVF file and managed as an entity. Continue reading Performance Assurance for Private Clouds
