With virtualization providing number of functional and operational benefits, many organizations are attracted towards adoption one way or the other. Virtual systems and networks are not only subject to the same attacks and vulnerabilities that exist in a physical infrastructure but also introduce new and unique risks. Also the sensitive data moves in virtual network and gets stored on a virtual infrastructure posing new challenges for compliance. Hence maintaining security and compliance when moving from physical to virtual and cloud environments remains the top priority for many firms. There are many guidelines and recommendations available for security and compliance, but…

With the adoption of private clouds, IT departments in enterprises are taking on a role that looks more like an IaaS provider enabling a self-serve IT model for internal business units. Users of IaaS clouds want to quickly provision their server, storage and network resources and expect the ability to easily modify them according to their dynamic needs. To achieve this, the IaaS cloud architecture should be such that the compute, storage and networking components can be easily provisioned and orchestrated. Several cloud management systems (OpenStack, VMware vCloud, etc.) integrate well with hypervisors (KVM, vSphere ESXi) and distributed storage systems…

Hybrid Cloud is a reality by now. It seemed a distant thing to do a year or two back. It all started with enterprises fast virtualizing their datacenters to grab the benefits of virtualization.

So today all enterprises first look at Private Clouds and then opt for Public Cloud services to save cost. Organizations only want Public Cloud services when Private Cloud is fully utilized. In other words, they…

With the proliferation and maturity of Cloud and Virtualization technologies, many industries and the public sector alike are coming to terms with the benefits of migration of applications to virtualized and/or cloud environments. At the same time availability of enhanced enterprise features like HA, scalability, fault-tolerance, etc. on these platforms is further propelling the conviction for adoption. Alongside, one of the most important factors is “cost”! While buzzwords like Public/Private/Hybrid Cloud are no longer unknown, a similar fire is seen in discussions about which model to choose over the others. Private Cloud continues to be adopted more and more as…

In technology, many entities come into contract and need to trust each other. For this, they create a federation by exchanging certificates or some other trust token. Once federation is established, they start trusting each other’s identity. In more technical terms we can consider the different entities as different domains. Why? Because there are chances that one organization may have different subsidiaries which could be considered as different entities. For example, Tata Steels, Tata Motors, Tata Power, TCS are all companies which lie under the Tata Group. They are different companies in the real world and logically as well. So…
