Many new companies are starting to test their hand at offering web-based application, storage, and services. While many companies including Amazon have done a decent job offering simple affordable solutions for small companies that don’t want to bother with bringing a highly available infrastructure in-house, their reliability, stability, and security still remains in question.
Randy George from InformationWeek wrote an interesting article, complete with survey data, that takes a look at what clouds could be reasonably be used for today:
- A secondary or Tier-2 disk layer
- Archiving non-critical data
- Cloud-based NAS
- Bulk digitization of digital records
- Client backups into your own cloud
What I don’t see on the list is Tier 1 applications, so companies looking to reliably provide Exchange mail service, SQL databases, and SharePoint farms probably still want to keep this stuff managed in-house.
