Cloud Migration Tools
Once it’s been decided that an organization is going to move to a virtual environment, and after it has been decided which cloud solutions are best, choosing the best cloud migration tools for the job comes next.
What Are Tools for Assessing a Cloud Migration?
Tools for Cloud Migration Definition: Tools for cloud migration are used in the actual process of moving applications and data to a virtual environment.
Forms of Cloud Computing
Each cloud form will have a different selection of utilities available for assessment/migration.
Infrastructure as a Service (IaaS)
The most common form of virtual environment is IaaS. When a company provides the infrastructure, they’re simply “renting” their hardware and maintaining it. The organization utilizing it has complete control over how the infrastructure is used.
Software as a Service (SaaS)
Many companies provide task-specific software that can be accessed anywhere on any device, referred to as SaaS. In these cases, the provider not only ensures the software runs efficiently, but also manages any data associated with it.
Platform as a Service (PaaS)
As more of a hybrid of the two, a PaaS consists of an environment with “bones” already established for the organization to build on top of while creating custom applications.

Cloud Migration Tools Comparison
To measure the readiness of application for cloud migration, automated tools provide an objective view of the potential issues (roadblocks) or currently used services (boosters) that will affect a migration to the cloud.
Despite the noble intention of fully automated programs, they do have limitations that may necessitate the use of manual utilities, particularly when one environment is not an exact copy of the other.
Choosing the Best Cloud Migration Tools
Because data may need to be moved from a local environment to a virtual one, or from one cloud to another, any tool selected must work with both interfaces. As mentioned earlier, each type of virtual environment will require distinctive tools as well.
Oftentimes, the company providing the cloud has its own proprietary software available to handle the migration or open source options are available. For example, those using Amazon Web Services (AWS) have three unmanaged options, including rsync, which works with a third-party file system tools to copy data directly into S3 buckets, the S3 command line interface, which moves data directly into S3 buckets with written commands, and the Glacier command line interface, which works similarly, but moves the data into Glacier vaults. On top of this, there are also managed options and choices for moving large amounts of data to AWS.
There is no “best tool” for a cloud migration, simply because each organization is starting in a different position and has unique goals. Because of this, it’s important to work closely with the service provider during the early planning stages to determine which utilities are available and ideal for the situation or to work with an established third party that’s familiar with any providers that may be involved as well as with the organization’s needs. Detailed information must be gathered well in advance that outlines the capabilities and drawbacks of any potential solution.
When you’re ready to assess the applications along with the infrastructure and dependencies, a solution like CAST Highlight can help identify potential blockers for migration to the cloud. This is an important step to understand what characteristics inside the application code may have to be changed in order to effectively move the application to the cloud. Some examples are Persistent Files, Use of Hard-coded IP Addresses, and COM Components/System DLLs.
