Cloud Migration is a complicated and intricate process.
There are few factors that needs to be considered when an organization is
migrating to cloud.
Data Management:
Data management should be a priority when moving to cloud.
Have an archival and DR strategy in place. Data frequently used by users that
does not change should be near the user. This can be in the form of cache.

Application Migration
Approaches:
We should promptly
plan for application migration based on short and long term business goals.
- Virtualization:
Virtualization
facilitates quick and easy migration of cloud as no alteration is required.
- Application migration:
In this process application goes
through a minimal architectural modification to make it optimal for cloud
deployment.
- Application Refactoring:
This model requires major
revamp of application right from the architecture to make use of the latest
technology stack.
Re-Platforming:
This is mainly done for platform compatibility issues.
Integration:
An organization may have their own application
and want to retain it in their premises, they also want this application to communicate to the applications in
the cloud. This could lead to performance issues if the applications are not
properly integrated.
Licensing:
The applications
should have a cloud based license to be deployed effectively in the cloud.
Security
Since your application/ Data will not be on premise and will
be sharing space in the cloud provider’s data-center with other organization’s
application there is a need to make sure that the applications are securely
protected from threats.
Automation
Automation is one of the major advantages of cloud
migration. Try to leverage automation as much as possible in your cloud
infrastructure. This can enhance performance.
Network configuration
Communication between internal applications should not be
through the internet to minimize costs and security risks. External
communication can be through internet.
Vendor Lock In
Vendor lock in can happen with cloud providers as
integration between different cloud providers is a difficult proposition. So
when looking for a cloud provider it is best to compare all the features before
choosing any particular cloud vendor. veeras.com
