I am starting a new company to analyze videos. Ill need a lot of storage as videos consume quite a bit of disk. Additionally, Ill need ample computational power, possibly running applications concurrently. I have discovered some very good tools to facilitate development in Windows but the deployment will be more effiicently handled in the Linux environment. All the pointers say that I need to move to cloud. I have found that SaaS is the most attractive service, followed by PaaS and IaaS, in that order. Given the above information, which service do you recommend. Why?
