There has been quite a bit of debate about SMB virtualization and what they want. However, no one has really looked into whether or not the SMB can afford virtualization. There is quite a bit of talk that says that the SMB wants everything for free, or that they will get immediate benefits from virtualization, but can they actually afford VMware, HyperV, XenServer, or KVM?

Last month Verizon expanded its Computing as a Service (CaaS) cloud computing offering. The expansion itself is not surprising. The interesting tidbit is that Verizon has Carrier Status and therefore different laws apply to them than any other cloud provider that does not have this status, such as Amazon EC2, Terramark, etc. Will cloud computing providers be the next internet service provider? If so will they have to battle to not be responsible for the content within their clouds, as did internet service providers with the battle that ensued over the Communications Decency Act?

The use of VMware VMsafe enabled third party products introduces third party fastpath drivers into your hypervisor. What these drivers ultimately do is interact with the VMsafe fastpath API, but is that ALL they do? That is why we need some level of certification for VMsafe fast path drivers. We need to KNOW that they do not do anything wrong, bad, or unfortunate.

Network security, virtual and physical, is extremely important however there is more to virtualization security than just your network. Here are some new ways to consider virtualization security.

Veeam has posted a blog of their own trying to explain why they are no longer selling Veeam Backup 3.x for the Free version of VMware ESXi. It is perfectly understandable that Veeam would comply with VMware’s requests in this matter as Veeam as a company depends upon their relationship with VMware to further their own business aims. In other words, Veeam has done nothing that could be considered wrong. However, VMware making the request in the first place should be a major concern to current and future vendors of VMware products.
