This is the third and last post in regarding the cloud lock-in. In the first and the second parts I covered the vendor lock-in of IaaS and PaaS. The appealing registration and the low cost overwhelm the new SaaS consumers that often makes them forget that eventually the service will become something they just can’t live without. What will happen if one day your SaaS vendor goes out of business ? In this post I will try to cover the threats and the actions the enterprise should take in order to lower the level of the SaaS lock-in risk.

SaaS use is actually the consumption of servers, operating systems, middle ware, network connections and more. Switching a SaaS vendor is much simpler as these are not located in your site – shifting to another vendor mainly includes migration of the data without the hassle of ripping and replacing the full app stack. This cheerful answer also provides a less costly and less complex switch than the painful effort and the risky investment of moving an on-site software.
