For the second year running, Surrey research was featured at the prestigious Cloud World Forum.
Presenting an overview of recent research conducted at the University on Cloud performance issues, Computing PhD student John O’Loughlin – who is supervised by Dr Lee Gillam – explained why ‘newer’ is not necessarily ‘better’, with implications for those using virtual machines and containers in public Clouds.
He spoke at the Cloud World Forum 2015, which took place on 24 to 25 June at London’s Kensington Olympia and was attended by representatives from the major global IT companies including IBM, Google, Dell and Equinix.
Cloud continues to evolve, with major vendors offering new services on a very frequent basis and often accompanied by price reductions. But there are various questions over whether new services at lower prices actually represent better value for money.
John commented: “Each generation of technology tends to bring a slightly different way of doing things. For example, each new processor model can have a differential impact on certain types of computational work - in some cases this will lead to better performance, but in others the performance will actually be worse than the last generation. The problem is, where performance is worse this can mean that if you are paying by the time the work takes to be done, you will be paying more. Knowing the amount of performance you can obtain at a certain cost for specific work means better value for money could be obtainable by every user”.
He added, “Presenting findings from your PhD in amongst those who are creating and trying to sell even more Cloud services, and informing users and buyers to be more shrewd in their purchasing – essentially, to pay less – puts one in quite an interesting position. The audience seemed quite appreciative, even if the vendors might have been blushing slightly”.
