Network virtualization platform NSX and Software Defined Data Center architecture
IT organizations have gained significant benefits as a direct result of server virtualization. Server consolidation reduced physical complexity, increased operational efficiency and the ability to dynamically re-purpose underlying resources to quickly and optimally meet the needs of increasingly dynamic business applications.
VMware’s Software Defined Data Center (SDDC) architecture is now extending virtualization technologies across the entire physical data center infrastructure. VMware NSX, the network virtualization platform, is a key product in the SDDC architecture. With NSX, virtualization delivers for networking what it has already delivered for compute and storage
VMware vCenter 6 Server is a service that acts as a central administration point for ESXi hosts and their virtual machines connected on a network. This service directs the actions of virtual machines and hosts.
Memory optimization is the most important feature of virtualization, especially for cloud computing and virtual desktop infrastructure (VDI) implementation where PCs are replaced by virtual machines running in the data center. This brings the necessity of using hardware resources more efficiently and host more VM’s.
Memory optimization is handled in a different method in each hypervisor. For example, Hyper-V uses a hot-add and ballooning technique and guest operating system is fully aware of memory amounts; while VMware uses over commitment technique.
