Introduction
Cloud migration
Is the process of moving applications, data or other business aspects to the cloud (Fahmideh et al., 2018)
Operational drivers that cause migration
One of the most prevalent motivations for companies to move to the cloud is to save money on IT infrastructure. IT leaders may simply right-size computer resources based on specific operational needs in the cloud, reducing wasted spending.

Improvements in IT agility, or the ability of IT to be more responsive to business demands and respond more quickly to market developments, are the most important technological drivers for 66 percent of organizations globally. Since a result of SaaS technology, this aim is particularly reachable in a cloud environment, as the IT department is no longer need to be distracted with conventional application administration activities. It is also simpler to upgrade and replace cloud technology in order to fit changing company requirements. Having said that, it's crucial to recognize that the cloud environment necessitates the development of a new set of IT skills in the areas of management and brokering of these goods. Additionally, although more agility can be beneficial to the internal customer experience by facilitating the introduction of new technology that users desire, it can also be detrimental to it by reducing IT's capacity to give professional assistance to users.

As cloud computing becomes more widely available, self-configurable, and cost efficient, a growing number of businesses are turning to it for their needs. With remote working becoming increasingly popular among businesses, cloud computing is empowering employees to work from any location, at any moment, and on any device. Mobility has emerged as a crucial driver of Cloud adoption in recent years, thanks to the maturity and acceptance of the smart mobile device industry in recent years. In the coming weeks and months, it is projected that more and more businesses will join the race to introduce new Cloud computing solutions of all kinds in order to become more efficient and acquire a competitive edge.

Stages of cloud adoption
In most cases, the organizations that use this book are in the "Project" stage of cloud adoption, throughout which they are beginning with a small number of employees and a few initiatives to gain an understanding of how they may use the cloud to solve a business requirement. As soon as a company has realized some benefit from the cloud through the deployment of a few projects in production, the company tends to progress to the "Foundation" stage, in which the company makes more extensive investments in its people, processes, and cloud foundation in order to scale cloud adoption throughout the company with the aim of realizing even greater business benefits. Migration follows which ensures data and other organizational applications are moved to the cloud. Optimization and reinvention follows which ensures the organization keeps adapting to changes in its environment.

The migration process
A critical initial step in preparing for data migration onto a publicly accessible cloud is determining the use case that will be accommodated by the service provider's public cloud. Important at this stage is the evaluation of the current environment and the identification of elements that will influence the migration, such as the presence of vital application data and legacy data, as well as application compatibility. It is also vital to understand how much you rely on information. Determining these requirements will assist you in developing a solid plan for the tools you'll need during the migration process, including trying to identify which information needs to be migrated and when, whether the data requires any scrubbing, the type of destination volumes to use, and whether you'll require encryption of the data both at rest and in transit, among other things. After your environment has been evaluated and a migration strategy has been developed, it is required to carry out the migration. The most difficult task here is to complete your migration with the least amount of disturbance to normal operations, at the lowest possible cost, and in the shortest amount of time. As soon as the data has been sent to the cloud, it is critical to guarantee that it is properly optimized, safe, and easily retrievable in the future. This tool also aids in the monitoring of real-time changes to essential infrastructure as well as the forecasting of workload contention.

Common migration strategies
Lift and shift, often known as rehosting, is the process of removing servers or apps from their existing hosting environment and moving them to a facilities in the public cloud. Rehosting and lift and shift are popular migration strategies for firms that are just getting started on their migration journey. Lift and shift are altered as a result of replatforming. During the migration step, replatforming makes adjustments to the application to make it more efficient. Drop end shop is a term used to describe the act of repurchasing anything. This refers to the choice made by the business to switch to a different product, which may entail terminating existing license and restructuring services on a new platform or service, among other things. Refactoring and rearchitecting are generally motivated by a great desire to improve the quality of services provided. The reason for this might be that it is impossible to enhance the present environment, or that it is necessary to increase availability and dependability promptly in order to fulfill certain security and compliance standards. During the course of a cloud migration project, you may wish to keep some aspects of the IT portfolio. However, there are certain apps that you aren't quite ready for migration to the cloud and would choose to maintain on-premises instead. If company find itself in this situation, it makes sense to keep certain components of the IT services in their present environment and undertake a mixed or part migration approach to replace them.
