Which is the best cloud migration company to work with? This question is on the minds of business leaders before they move their on-site resources to the cloud. But there is no magical tool that will just give you the answer, unfortunately.
However, finding the best cloud migration companies is not that difficult if you do some research diligently. Usually, businesses just look at big corporate names and think they will just do the job. But bigger is not always better.
Cloud migration is a tricky and complex process. The right cloud services partner matches your data resources with the appropriate technologies to make sure everything works the same in the cloud as it did before.
In this blog, we have done that research for you by listing the 10 best cloud migration companies in the US. These companies offer the expertise and skills to undertake cloud migrations effectively.
Why you need a cloud migration company?
Cloud migration could be for whatever reason, like updating a legacy application or adopting a hybrid model. Regardless, it is a big step because you’re shifting from one tech environment to another.
And the cloud is a vastly different environment altogether. Cloud platforms like AWS and Azure offer hundreds of services that come with their own technical details. Cloud platforms also tend to be more regulated than on-site environments due to higher risks of security threats.
Therefore, it is often the case that apps or tools that work perfectly onsite go kaput in the cloud. Their data or some component is corrupted during the process, or it is transferred to the wrong cloud resource.
This leads to the next issue, that not everything moves the same way to the cloud. There are six different ways of approaching cloud migrations, which are mentioned in the table.
| Approach | What it does |
| Rehosting | Moves an application to the cloud with little or no change. It is also called lift and shift |
| Replatforming | Makes small tweaks like OS updates during the move |
| Refactoring | Rebuilds the entire app from the ground up using cloud-native technologies like microservices |
| Repurchase | Replaces an old system with a SaaS product |
| Retain | Keeps some system on-premise because latency or regulatory reasons |
| Retire | Shuts down the system if it’s not worth moving to the cloud |
So, there are tons of permutations and possibilities in cloud migration that you need to be aware of before migrating to the cloud.
Cloud migration companies help make those decisions easier. They perform a complete assessment before anything begins. They look closely at how applications and systems depend on each other, and what would happen if they’re just yanked to the cloud.
Then, cloud migration consulting services choose the best migration approach and technologies.
Doing all of that on your own is almost impossible unless you have a big enough internal cloud team that knows every nook and cranny of both the cloud and your on-site infrastructure.

Closing remarks: Things to spot in cloud migration companies
We did the best of our research and inference in picking this list of cloud migration companies in the US. However, the final choice to select the right partner will always require your own prudent judgment.
So, it is pertinent to end this blog with the main factors that you should look for in a cloud migration company before making your decision.
1. Verify technical expertise
Always ask for proof to back up claims. Look for advanced credentials from AWS or Azure to judge their competence. These are good signs that they can handle things if they go wrong.
While certifications do prove your partner has the expertise, they are not the end of everything. Some cloud migration companies have done actual work to back up their claims, even if they don’t have the certifications. So, you can also look for case studies and prior experience as well.
2. Prioritize automation and DevOps expertise
Great cloud migration companies don’t manually configure infrastructure. It is an outdated method that creates technical debt in the long run. Therefore, only consider cloud migration companies that use Infrastructure as Code (IaC) tools like Terraform or CloudFormation.
Additionally, ask about their CI/CD integration approach to make sure they improve your entire development lifecycle.
3. Demand industry-specific compliance expertise
If you operate in Healthcare or E-commerce, your migration partner must deeply understand HIPAA and other requirements within cloud environments. The best cloud migration companies embed Compliance-as-Code directly into your cloud foundation,
You need to be proactive in this aspect because it prevents costly legal reviews later and protects your brand reputation.
Conclusion
Gone are the days of decentralized computing of the 90s. Almost everything is in the cloud these days, and it will likely stay that way for a long time. “At some point, the only thing you will be able to do as a company is to use the cloud,” says Cecilia Rikap, an economics professor at University College London.
