Once a business has decided to migrate to the cloud, the most critical process of planning and developing cloud integration starts. But despite knowing how essential it is to thoroughly plan how a business will move from on-premises IT setup to a cloud-based system, most companies give far less thought and time to it. The reason can be tracked down to lack of appropriate resources to incorporate computer storage solutions or IT support.
Having a poor migration plan is next to having no plan. Without planning the move properly, no business can reap the advantages of the cloud server and complete the procedure in time. Contrary to what most business owners think, cloud migration is not a little up-gradation of existing hardware and software instead it involves redesigning the entire IT systems and applications to facilitate communication of systems with end users. Since small businesses lack IT assistance and support for cloud migration, many IT support firms provide small business it support services.
When migrating to the cloud, a business needs to consider factors that are critical to its success. Here is a list of things to keep in mind before planning cloud migration.
- Resource usage versus availability:
Most often, the bare minimum requirement for applications to be compatible with cloud exceeds the actual usage requirement. For a cloud environment to function correctly, it is essential that its specification and utilization matches with the resources and applications available with the business.
How the applications are licensed has a direct effect on its cost. Licensing cost can significantly increase if the licensing model necessitates accounting of all the applications whether or not allocated to the business. Likewise, if the licensing model is based upon per core and the cloud service provider does not provide the service of configuring the cloud infrastructure per core, it will adversely impact the total cost on licensing.
- Existing access mechanisms:
One of the most essential things to consider when migrating to the cloud is how the users access the applications in the current scenario and how it would alter once you move to the cloud. It is also important to consider how the cloud will affect user experience and how to prepare them for the shift better.
Besides networking systems, an organization needs to make sure that an adequate level of security measures are deployed in the cloud system. You might need to alter your security policies or adhere to industry compliances to ensure that your business is protected from threats.
Most often if not always, businesses find out application dependencies too late when processing cloud migration. This results in unplanned outages and reduced productivity of systems. Thus, when planning cloud migration, it is essential to understand how applications communicate with their users and themselves.
The architectural design of a cloud is also determined by the requirement for data protection, how and when replication occurs and the need to align RTO and RPO.
