Amazon Wants to Replace the Enterprise Data Center

Working at BigCo doing work with our internal enterprise data centers that are spread globally a few concerns would come up.

- How secure are the AWS offerings in comparison to a company's internal offerings?

- How cost effective is it? If a company's internal cost is the same monthly rate, roughly speaking, transitioning from internally hosted to AWS would be a huge effort and could take many years. Case in point is Netflix transitioning to AWS took a few years and they are "new" compared to larger older companies.

- A huge amount of re-architecting applications would need to occur to work on AWS for nearly any company. These are critical apps that were written a decade ago but keep the bits flowing on old technology.

The plus side for a big company would be for new projects. It takes eons to get infrastructure and storage for something - like months. If I could fire up VM's and storage in a day or two, projects would move insanely faster.
