The act of moving apps and data from one place—typically a company’s own, on-site (“on-premises”) servers; to the servers of a public cloud provider, as well as between other clouds, is known as cloud migration. Reducing IT expenses and enhancing performance are the two key advantages of cloud migration, but there are additional perks including ease and security.
Learn more about the many migration kinds, typical advantages and difficulties, moving data and apps to the cloud, and the three primary managed service models (IaaS, SaaS, and PaaS) by continuing to read.
In most migrations, there are two essential technical factors:
In addition to giving an overview of various migration procedures, best practices, and business concerns, this part describes some of the most typical migration cases.
The process of transferring data from on-premises servers and mainframesŮ« which are frequently kept in a server room at an organization’s headquartersŮ« to the servers of a cloud provider, which are usually located in sizable, extremely secure, and well-maintained facilities, is known as data center migration.
The most popular method for moving data center resources to the cloud is through high-capacity networks; however, in situations where a strong network is not available, the resources can still be moved using high-capacity disks and “data boxes” before being directly shipped to the provider of the cloud and uploaded to their servers.
A “hybrid cloud” is created when a business decides to migrate part of its resources to the cloud and keep the rest in its on-site data center. Benefits of hybrid cloud computing include optimizing the investment in current on-premises data center infrastructure and helping some businesses comply with legal and regulatory requirements.
Hybrid clouds are particularly helpful for cloud-to-cloud backup, which is a disaster recovery strategy that stores data on-premises in the public cloud in case the on-premises data center is destroyed by fire, flood, or other natural disaster. (Here, “cloud to cloud” refers to on-premises data centers that are occasionally referred to as “private clouds.”)

Since cloud computing has become so widespread, many businesses use numerous clouds—often as a result of mergers and acquisitions—and occasionally they decide to use cloud-to-cloud migration to transfer resources between their public clouds. When a company wishes to benefit from the many offerings, services, and costs of cloud platforms, this kind of transfer is also helpful.
While it may appear challenging to manage resources across several clouds, a central management solution makes it easy to do so from one location.
