OneCloud Lets VMware Sites Use AWS for Disaster Recovery

OneCloud Lets VMware Sites Use AWS for Disaster Recovery:

While VMware IT environments clearly dominates traditional businesses that deploy their own servers, the public cloud is dominated mainly by the instances of a custom Xen hypervisor. Clearly, IT organizations running VMware would like to be able to use inexpensive public cloud for disaster recovery, but it can be problematic, given the different hypervisors involved.

To answer this question OneCloud Software unveiled this week OneCloud recovery software that can be installed in 30 minutes enabling IT organizations to cases based on VMware virtual appliances available on the Amazon Web Services (AWS) cloud. In case of failure, the applications running on VMware can be redirected to the AWS cloud until the premise systems can be restored.

Based on an automated cloud engine (ACE), said CEO Marc Crespi OneCloud OneCloud Recovery Software installed within VMware vSphere. OneCloud recovery discovers that all local authorities and VMware administrators can invoke a policy engine to allocate recovery time objectives anywhere between one and 24 hours.

Before running VMware site recovery OneCloud must either invest in a second data center to create a disaster recovery site or make use of cloud services running VMware. In the latter case, said Crespi these services have not the same scale as AWS, which thus makes them more expensive to use for disaster recovery. Moreover, Crespi said OneCloud Software has optimized the application process reads and writes between VMware and AWS in a way that minimizes the bandwidth consumption of the network. Once installed, ACE takes a snapshot of the VMware environment every four hours; with only the deltas changes in the local environment is copied to VMware AWS.

Naturally, ACE could probably be applied to other platforms such as AWS cloud, but refused to other commitments Crespi public cloud. From a market share Crespi says AWS public cloud is clearly most IT organizations want to use. Moreover, Crespi said AWS has also been certified to perform some of the most sensitive government applications, giving organizations confidence in AWS as a platform for disaster recovery.

Typically, disaster recovery is clearly the first and most dominant form of hybrid cloud computing that most IT organizations embrace. Eliminating the need for investment in secondary data centers to ensure the availability of applications is an expensive proposition. Of course, many IT organizations have always depended on hosting providers to minimize these costs. But given the low cost of cloud storage AWS Crespi it said it is now difficult for hosting providers to compete with the prices of AWS.

For many solution providers and their customers of AWS has become the path of least resistance to the cloud, which often usually starts with some sort of disaster recovery software.
