The key to a successful cloud migration is an experienced partner.

Organizations that migrate their data and applications to the cloud waste approximately 30 percent of their cloud spend because they don’t have their environments configured correctly or the migration takes longer than they planned. By working with a cloud migration services provider, companies get an experienced partner that can identify pitfalls and avoid them during the transition.

To help you navigate this difficult change, we’ve put together a list of the best cloud migration companies.

Finding the Best Cloud Migration Service Provider

What Does a Cloud Migration Services Provider Do?

Exactly what is a cloud migration services provider? Cloud migration services providers are third-party businesses that help organizations through the complex process of data and application migration to the cloud. They’re typically vendor agnostic, meaning they can work with any cloud provider (AWS, Azure, IBM, etc.). This means they can make a more impartial recommendation about which cloud environment will actually meet a business’s needs.

Cloud migrations aren’t easy, but it’s typically not cost-effective for every business to have a cloud specialist on its staff, especially with the current shortage of IT professionals. Instead, these businesses can contract with cloud migration providers to handle the migration and any necessary reformatting and keep their in-house IT staff focused on current projects.

Benefits of Hiring a Cloud Migration Service Provider

Here are the benefits companies can expect when they hire a cloud migration service provider.

Experience and expertise

Most businesses will only go through one or two cloud migrations in their lifespan, but cloud migration services providers handle them all the time. This means they understand how to navigate common pitfalls and can speed up an organization’s time to value. Your cloud migration provider will be able to provide recommendations on the type of cloud environment you should use as well as any additional applications you’ll need. They can also tell you what the best method of migration will be for each of your applications and datasets.

In-house IT staff stay focused on jobs

With cloud migration services providers, you won’t have to pull in-house IT administrators away from their day-to-day work to handle the cloud migration. Instead, the provider will handle migration-related tasks, so your IT professionals don’t become overwhelmed. It’ll also keep your day-to-day operations running more smoothly because your support queue won’t become backed up in the same way it would if you split the focus of your IT department.
