AWS migration often involves more than transferring workloads from one environment to another. Application architecture, databases, deployment pipelines, integrations, security, and legacy code may all need attention during the transition. The companies below approach AWS migration from different angles, ranging from infrastructure engineering and DevOps to application modernization and cloud-ready software development.
1. OSKI Solutions
OSKI Solutions handles AWS migration alongside custom software development, infrastructure modernization, and DevOps. Migration projects can involve existing applications, databases, integrations, and older hosting environments that need to move without disrupting normal business operations. The team works with AWS together with Docker, Kubernetes, Terraform, CI/CD pipelines, .NET, Node.js, PHP, and modern frontend technologies. This combination is useful when a migration requires more than rehosting and parts of an application need to be refactored, replatformed, or rebuilt for a cloud environment.

3. Gilzor
Gilzor works on cloud migration primarily through software modernization and product engineering. Its capabilities include moving infrastructure to cloud environments, refactoring legacy code, modernizing databases, developing APIs, and preparing applications for modern deployment workflows.
AWS forms part of the company’s cloud and DevOps technology stack alongside Docker, Kubernetes, Ansible, and CI/CD tooling. This makes Gilzor particularly relevant when a migration cannot be handled as a straightforward rehosting project. Applications that require architectural changes, code restructuring, integration work, or performance improvements can be modernized alongside the AWS transition.

4. Itexus
Itexus combines cloud infrastructure work with DevOps and custom software engineering. Its cloud capabilities cover AWS, Azure, Google Cloud, and IBM Cloud, with services that include infrastructure assessment, cloud setup, workload migration, infrastructure as code, monitoring, backup, and recovery.
The engineering stack includes Terraform, AWS CloudFormation, Docker, Kubernetes, Ansible, and AWS CodePipeline. This gives Itexus a practical fit for AWS migration projects where infrastructure changes must be coordinated with application development and deployment automation. The company’s experience in fintech can also be relevant for cloud projects involving transaction-heavy applications, financial platforms, or systems with demanding security and reliability requirements.

5. Mobian Studio
Mobian Studio approaches migration from the application engineering side. Projects can begin with an assessment of an application’s architecture, dependencies, performance, and compatibility before the migration plan is prepared. The company also provides development, modernization, integration, maintenance, and post-migration support.
This approach is relevant when an AWS transition involves existing software that needs technical changes rather than a simple infrastructure transfer. Applications may require updates to architecture, integrations, deployment processes, or supporting services before they can operate effectively in a new cloud environment.
Key Facts
- Best for: Application-focused cloud migrations
- Core services: Application migration, software modernization, cloud integration, development
- Migration stages: Assessment, planning, implementation, post-migration support
- Project focus: Existing applications and digital products
- Notable strength: Migration handled alongside application development

6. .NET Developers
.NET Developers combines enterprise software engineering with cloud architecture and migration work. Its AWS experience includes moving production applications between cloud environments and rebuilding supporting infrastructure using AWS services.
A published migration project involved transferring a large public platform from Azure to AWS without a disruptive single cutover. Technologies used included ECS Fargate, RDS, S3, EC2, containerization, and load balancing. The wider engineering practice covers .NET, Java and Kotlin, Node.js, Python, Go, infrastructure as code, CI/CD, automated testing, and production deployment.

7. SoftPro
SoftPro provides cloud migration and cloud development services across AWS and Microsoft Azure. Its migration capabilities cover applications, data, and infrastructure, including transitions from existing hosting environments as well as moves between cloud platforms.
Cloud-native development, infrastructure management, hybrid and multi-cloud architecture, cloud security, and data storage can be incorporated into a migration project. SoftPro also develops and modernizes business applications, which is useful when AWS adoption requires software changes rather than infrastructure work alone. The company is therefore a practical option for organizations planning to modernize applications while moving workloads into AWS.
Key Facts

8. 21century.tech
21century.tech focuses on production software engineering, legacy refactoring, integrations, CI/CD, testing, and deployment. Senior engineers remain responsible for architecture, business logic, security decisions, code review, and production delivery, while AI-assisted workflows support coding, testing, documentation, and large-scale refactoring.
For AWS migration projects, the strongest fit is application modernization. Older systems can be refactored, integrations rebuilt, deployment pipelines prepared, and production applications adapted for modern cloud infrastructure. This model is particularly relevant when moving to AWS requires substantial changes to the software itself rather than simply transferring existing servers into a new environment.
Key Facts
- Best for: Application modernization during AWS migration
- Core services: Legacy refactoring, application development, integrations, deployment
- Delivery capabilities: CI/CD, automated testing, documentation, production deployment
- Engineering model: Senior-led development supported by AI-assisted workflows
- Notable strength: Refactoring and rebuilding applications for modern infrastructure

Conclusion
AWS migration is rarely just a matter of moving workloads from one environment to another. The real work often sits in the details: deciding what should be rehosted, what needs refactoring, how databases and integrations will move, and how security, deployment, and monitoring should work once everything is running on AWS.
The right AWS migration company depends heavily on that starting point. Some projects need deep infrastructure and DevOps expertise, while others are driven by legacy application modernization, cloud-native development, or a move between existing cloud platforms. Looking closely at technical capabilities, migration experience, post-migration support, and the ability to work with existing systems makes it easier to narrow the field and choose an approach that fits the actual workload rather than forcing every migration into the same model.
