Moving to cloud has been the talk of the boardrooms for a long time. Many startups have launched their products using different cloud providers and few have been moving on an off cloud. One example I particularly remember is when when San Francisco based social gaming company Zynga reached its own hyper growth phase, the company moved off of the cloud and into its own data centers. But then its business imploded, and it was left with infrastructure it didn’t really need. It’s now back on Amazon. (Read full story here)
While the companies are busy planning their migrations to cloud, but at the same time we should plan for the moving between the clouds, to avoid vendor lock.
Data migration is a particular problem because a cloud storage service is often seen as the ultimate data archive and the capacities an organization will try to transfer can be very large — petabytes instead of terabytes. Migrating large data sets is always a challenge, but public clouds have the additional issues of limited bandwidth and potential download fees.
Wired magazine recently published the story on Dropbox’s Exodus From the Amazon Cloud, following is an extract:
“Just getting the bits out of Amazon and into other data centers was an epic task. Digitally moving petabytes of data from one machine to another isn’t exactly on the same scale as downloading a few songs for your laptop. Even the fattest Internet pipes only have so much bandwidth.”

Moving those bytes around is a huge task. Even small and middle size companies will have to face this challenge in due time.
