What is Cloud Migration?
In the simplest of terms, cloud migration involves the process of moving relevant business data, applications, and other important elements of an organization from its desktops and servers to the cloud.Cloud migration makes cloud computing possible, wherein the cloud performs all the computing that was earlier performed by mobile devices, laptops, or desktops.At the same time, cloud migration challenges are still an important reality that many companies wake up to unless they partner with an experienced service provider.

There are 3 basic types of cloud to which cloud migration can take place, and service providers offer their services accordingly. 

These include 

IaaS (Infrastructure as a Service)
IaaS forms the basic foundation of cloud computing and includes data backup, data storage, and data security. AWS or Amazon Web Services is a typical example of IaaS service provider, who offer databases, storage, private virtual servers, and other support services on demand and bill by the hour or by data consumed.

SaaS (Software as a Service)
SaaS providers generally provide access to internet-based software for corporations and businesses on a monthly rental basis, or in some cases, based on per-user basis. Some SaaS applications need extensive customization and vendor support, while others are more manageable and can be set up easily by regular users or a company's IT admin.

PaaS (Platform as a Service)
Many people consider PaaS to be the next evolution for the cloud, wherein the PaaS vendors provide an entire framework and basic functions using which their clients can develop their own applications. Microsoft Azure and Force.com from Salesforce are perfect examples of PaaS service providers.
