In such a technological and digitalized world, the information of systems, companies, and individuals is infinite. Under this scenario, and also pointing out the risks of having so much information, it is essential nowadays to migrate to the cloud, regardless of the size of the company.

However, it is not easy to just arrive and transfer the data. To do so, it is necessary to have methods to implement it optimally. Furthermore, it is important to note that there are different ways to migrate to the cloud, the 4 most well-known types of migration being: rehost, refactor, rearchitect, and rebuild.

These types are not mutually exclusive, meaning that in the case of large companies or when there are departments with very specific needs, they can be combined. However, the refactor migration type is the favorite, in fact, it will be necessary to use it when the following occurs:

1. The operating system we are using no longer has support.
2. We need to modernize software (such as SQL) and require a more up-to-date operating system.
3. We want to reduce maintenance costs.

Migrate to the cloud

Refactor migration involves decoupling the elements or services running on the server from the operating system layer. To achieve this, it is necessary to generate an exact copy of the server and place it in the cloud.

Teams involved in this type of migration plan, design, and migrate complex or mission-critical enterprise applications that have many dependencies. To accomplish this, they require the use of certain tools.

Refactor migration can be achieved through several steps, and for that, it is important for companies to be aware that they will need to undergo some changes in their systems, such as modifying the connection string and the public DNS records.
