Den 8. marts kunne vi bringe nyheden om, at vi skulle besøge Dells hovedkontor i Danmark, for at få en snak med en af deres top-folk inden for cloud-computing, Marcel van Drunen.

I forbindelse med nyheden bad vi jer læsere om at komme med spørgsmål til van Drunen, der har titlen Senior Enterprise Technologist, med ekspertise inden for Cloud-computing og HPC (High Performance Computing).
Det blev til 15 udvalgte spørgsmål fra jer og redaktionen, som van Drunen tog sig god tid til at besvare, hvilket vi har klippet sammen i videoen herunder.
Vi vil i den forbindelse gerne takke jer som kom med spørgsmålene og van Drunen for hans tid.

Tidslinjen for alle spørgsmålene kan du læse herunder (på engelsk).
00:00 – Intro
00:14 – 1) What do you do at Dell?
00:58 – 2) A server on the internet is nothing new, but how large must a setup be, before it – in your opinion – classifies as a cloud solution? Is a single powerful server, which offers for example a database-service, enough?
03:10 – 3) When is a service a cloud service? For example must it be a complete virtual computer, a web application or a database where you pay depending on usage?
09:11 – 4) Which service do you think is the toughest to setup as a cloud service – which is the easiest?
12:12 – 5) Based on your experience, what service would a company gain the most of by moving it to the cloud (cost benefit)?
14:21 – 6) With services such as gaming moving to the cloud (OnLive), a service that previously was thought unheard of as a cloud service, what services do you see as a cloud service that, at the moment, aren’t technically feasible? Du you see any limit for what could be a cloud service?
15:51 – 7) With many servers making up a cloud system, there is an increased risk of bit errors. Is this a problem that’s given special consideration, or do the normal error correction in the servers handle this?
17:20 – 8) Personal information about people, especially in regards to local authorities and privacy laws, could be a showstopper for using cloud services. Does a technical solution exist that tackles this problem, for example hardware encrypting the data, ensuring not even the provider is able to access it?
21:39 – 9) Both Nvidia and ARM are planning to enter the server market, focusing on power efficient processors. Are we going to see more cloud systems based on these kind of processors in the future, aiming for a better power/performance-ratio?
23:55 – 10) Do you see a future for distributed cloud systems? In many companies hundreds or thousands of clients are idle most of the time, leaving massive resources unused.
25:55 – 11) Do you see cloud services one day reducing most computers to thin clients?
26:35 – 12) Designing a large cloud system, what is the most important aspect to focus on? Network, storage, servers? Where is it most likely you will experience a bottleneck in a cloud system?
28:29 – 13) What is the typical savings in hardware (percentage) for a company choosing to use cloud services?
30:01 – 14) Which high availability precautions are typically made, in regards to hardware, to ensure the safety for a service? What would you recommend a customer demand from a cloud service provider?
33:15 – 15) Besides Dell there are a lot of other players on the market selling cloud systems. Is there any kind of standard being made for these systems, ensuring that customers can easily compare them, and maybe migrate from one system to another as easy as possible?
