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.
