When discussing IBM Cloud for VMware Solutions with partners and customers, I repeatedly encounter three common misconceptions about the security of their workloads in the IBM Bluemix dedicated private cloud infrastructure. I’d like to take a moment to clear up the myths surrounding VMware security in the cloud.
Occasionally, security vulnerabilities are reported against various hypervisors. While public cloud providers are quick to patch these vulnerabilities, it is fair to be concerned about the security of shared servers. But with IBM Bluemix bare metal infrastructure, your VMware workload runs on dedicated servers that are not shared with other customers, and you have full control of the hypervisor installed on the bare metal machine. You can rest assured that no other workload is sharing your server.
While public clouds do not provide segregation of network traffic, the IBM Bluemix infrastructure dedicated private cloud provides dedicated network VLANs to segregate your network traffic from all other customers. You can rest assured that your network traffic is not visible to other workloads. For access to your VMware workload, several public and private connectivity options are available for you to connect to your intranet or even the Internet at your discretion.
Regulatory and industry standards may require you to prove the location of your data or to audit all access to it. This can be difficult in public clouds that use a shared storage infrastructure. By contrast, IBM Cloud’s VMware Cloud Foundation offering uses VMware vSAN technology in combination with local storage on your IBM Bluemix bare metal instances to provide highly available fault-tolerant dedicated storage. VMware vSAN virtualizes and mirrors the disks on the bare metal servers themselves to provide a virtual shared data store spanning the systems. Your data remains on your physical servers at all times.
If you’ve despaired of using public cloud infrastructure due to VMware security concerns, why not take a second look at IBM Cloud for VMware Solutions on IBM Bluemix’s dedicated private cloud? I also encourage you to explore IBM Cloud Secure Virtualization, which combines Intel and HyTrust technologies to add workload encryption, access control and auditing, and geofencing capabilities to your VMware cloud.
