Cloud Application Migration

The most important consideration for cloud migration is security.

Gaps in security can occur while the data is being moved, and certain security policies may need to be strengthened or relaxed in order to move successfully.

A more comprehensive model is required to monitor Network Security.

Moving data to a new cloud storage service provider may require network security to be reworked or reconfigured.

Licensing costs can increase massively when migrating to cloud storage.

Organizations should review their licensing contracts and adjust accordingly before migrating, which will save organizations from surprise fees that can put a migration project over-budget.

Data must remain accessible during transition, or providers risk a drop in productivity    Organizations can choose to migrate users as a group or all users at a time depending on the IT resources and data being accessed.

Groups can be determined by permissions or on department basis.

Enterprise applications also need to be reconfigured for migration. Each application should be reviewed to ensure compatibility with the new storage platform. Scaling, reconfiguration, and restructuring of applications must be completed prior to migration.

Reconfiguration and reworking will be required often, but it need to be done carefully, without any loss of data.

Replicating the current environment takes time and needs to be done carefully without risking live compatibility issues that result in loss of data.

Changing an application that is currently in use to fit the new cloud storage method can affect compatibility with an organization’s current system.

Users cannot be accessing data that is being reworked for a new storage environment.

Tools are needed specifically for migrating data to create a new environment without tampering with the existing data.

Working on a duplicated environment prevents theses errors from affecting daily usage and gives IT experts time to correct issues if any arise.

Most large vendors such as Amazon Web Services (AWS), Microsoft Azure, etc.

Will duplicate the environment when transitioning data, which is a common feature of most cloud service vendors.

Also, in the unlikely event of any migration interruption or security breach, there is a complete replication of all transitioned data.

Once data is successfully transitioned, deduplication is the last step.

There is no longer need for the copy of the data center taking up space, so all duplicate files need to be deleted to make room for new data.
