Every year, more and more companies are inclined to transfer their business processes to the cloud. There are several reasons for this: reducing capital costs, saving time, relieving IT staff of equipment administration responsibilities, and the desire to keep up with the times.
However, many people associate the process of cloud migration with headaches, data loss and long downtimes. In practice, migration is a very simple process that, with proper preparation, will take no more than a few days, depending on the volume of infrastructure being transferred.
In this article, we will talk about how to prepare for cloud migration, what nuances should be taken into account when choosing a provider and, finally, how to move IT infrastructure to the cloud and avoid downtime.

Cloud Migration Options
In some cases, a complete migration of the entire IT infrastructure of a company to the cloud is impossible. The scenario in which only selected systems are transferred to the cloud is called partial migration. If a business completely refuses to use on-premise infrastructure, a complete migration is performed. What are their features and non-obvious differences?
Partial migration to the cloud
Partial migration is a common choice for large companies with complex IT landscapes. In a partial migration, the least important services, such as test beds, user virtual machines, are migrated first, and then everything else.
Full migration to the cloud
During a full migration, the customer's entire IT infrastructure is sequentially transferred to a cloud provider. On average, this process takes from one to several weeks, depending on the complexity and number of systems being transferred. Most often, small and medium-sized companies resort to full migration, whose business is not directly related to IT and, accordingly, the architecture of IT systems is relatively simple.
Preparing for Cloud Migration
So, you have a clear goal for moving to the cloud and have chosen a provider. What to do next?
Audit
