The client hosts its application using the infrastructure of external providers. The most important players in this area are the big three from the Gartner report. In the case of rehosting you may also encounter the name Lift and Shift. Lift and shift is nothing more than a strategy for moving applications and data from the onpremise environment to the providers cloud environment. Historically application rehosting was used for more complex applications. Currently it is often used in the context of microservices and containerization because this migration strategy works precisely for microservice applications and those that are optimized for private and public clouds. When should you decide to rehost? Rehosting is a good choice when we want to reduce the costs associated with maintaining or replacing equipment and gain access to innovative solutions such as new applications.
Advantages Fast migration thanks to no interference with the architecture. Lower initial expenses so it is a good option for smaller and growing businesses that do not want to invest in physical equipment. Reduce ongoing costs such as equipment maintenance and management. Scalability Email Marketing List and availability on demand if necessary you can increase the amount of resources e.g. virtual machines. Greater opportunities in the long term for the use of payperuse services. Defects The responsibility for migrating existing data resources and applications lies with the companys IT departments. The architecture remains unchanged so it may not be possible to use the full potential of cloud services.
Compared to other migration models the provider is still responsible for managing data and applications as well as middleware and the operating system itself. Possibility of changing the service delivery strategy by the infrastructure provider and predefined conditions for using a given service. No further customization of the transferred application to the cloud. In the longer term there may be a need to invest in additional computing capacity. Refactoring i.e. redesign and use Application refactoring is also known as Platform as a Service.
