Migration issues such as the risk of vendor lock-in. What is IaaS? IaaS or infrastructure-as-a-service this service offers the computing architecture and infrastructure that is it offers all computing resources but in a virtual environment so that multiple users can access them. These resources include data storage, virtualization, servers and networking. Most vendors are responsible for managing the above for resources.
