Cloud based infrastructure deployment is becoming more and more appealing to customers, from Fortune 500 companies to SMEs due to its pay-as-you-go model. Enterprise storage vendors are able to reach out to these customers by integrating in cloud based deployments; this needs adaptability and interoperability of the products confirming to cloud standards such as OpenStack, CloudStack, or Azure. As compared to off the shelf commodity storage, enterprise storages by its reliability, high-availability, efficient and greener solutions can offer much reduced operational expenses (OPEX) to the cloud service providers. Further considering the reduced OPEX, voluminous deployment in cloud environment, lesser form factors (i.e. reduced real estate investment) and intrinsic design solutions, capital expenses (CAPEX) becomes much equitable and compelling proposition. This white paper also discusses how Calsoft can resolve the technical challenges of integrating storage in the cloud with various approaches, backed by understanding of both cloud requirements and the capabilities of large class of enterprise storage products.
