PrintThe event’s second keynote speaker was Erison Oktavian, CIO of PT. Essar Indonesia. Oktavian highlighted the importance of best practices for virtualization. The ROI for virtualization might appear compelling, but virtualization could be badly implemented in terms of costs, management strategy and the approach to architecture and software, Octavian said.
VM sprawl was more dangerous than server sprawl, and Oktavian warned that not all applications were ready for virtualization, with many vendors not licensing or pricing their products for a virtual environment.
Additional concerns users had to take into account included the need for wider bandwidth and whether encryption could be performed on the fly. It would be highly difficult to quantify the real cost of going virtual, due to all the factors involved, said Oktavian.
Ed Lenta, GM of VMware ASEAN next took to the stage to discuss the evolution of infrastructure-as-a-service. Lenta said public clouds should be viewed as an extension of the data center, and said the audience should look to a world beyond Windows, where the Windows operating system gets takenoff the device and back into the private cloud.
There was enormous opportunity for enterprises to break apart the Windows desktop, Lenta said.
The fourth keynote speaker, Mike Usher, director of information risk at Prudential Asia spoke of his company’s challenges with developing a framework for governance in cloud and virtualized environments.
Prudential Asia, which operates across 13 countries in the region, was under immense pressure to allow its staff to use their own devices to access confidential data, and having to comply with regulations from the global headquarters in London made developing a framework even more complicated.
Risk management and governance had not quite kept pace with virtualization and cloud computing, although security generally kept pace with new technology developments, said Usher. Businesses ultimately had to agree on a level of risk that was acceptable to the business, said Usher. Governance had to be holistic and there lies a tendency for corporate governance and risk management to not encompass everything.
