Virtualization continues to expand from desktops to servers to switches, routers and firewalls. Virtualization will provide a much higher level of control of these devices rather than saving money. In fact, the organization's infrastructure will require larger servers, more VM licenses, and emulation software in addition to the continuing cost of desktop licenses.
A virtualized data center requires many of the same management tasks that also must be performed in the physical server environment. These tasks need to be extended into the virtualized environment as well as integrated with the existing workflow and management processes.
One example is that IT organizations must be able to automatically discover both the physical and the virtual environment and have an integrated view of both environments available for monitoring and managing. That view of the combined virtual and physical server resources needs to stay current as VMs move from one host to another. The view must also be able to indicate which resources are involved in the case of fault or performance issues.
To address this issue:
In January 2013, the Distributed Management Task Force (DMTF) set its virtualization management (VMAN) standard. That includes a set of specifications to address the management lifecycle of a virtual environment. VMAN's open virtualization format (OVF) specification provides a standard for describing virtual machines and applications for deployment across various virtualization platforms. VMAN's profiles now standardize many aspects of the operational management of a mixed vendor virtualized environment.
According to Paul Simoneau, a senior instructor and course director with Global Knowledge, the coming year will have 12 main challenges for IT management and staff. Since each organization is unique in how it functions and where it places its priorities, these are offered in no particular order. The issues include new technology, cloud, Big Data, virtualization, BYOD and BYOA, shadow IT, boomers, energy efficiency, user systems, interoperability, creating value, and social networks. After a brief comment on each area, more suggestions for dealing with that situation follow.
Future IT leaders will need to seek technologies that eliminate silos in order to deliver the right information to the right person within the right application environment at the right time. ... More >>
