Top 22 AWS Development Companies (2026)
AWS development goes well beyond moving an application onto EC2 or configuring storage. Product teams increasingly use AWS as an application platform, combining managed databases, serverless functions, containers, event-driven services, infrastructure automation, observability, security controls, and data tooling within the same production environment.
That makes the choice of an engineering company highly dependent on the work ahead. A new SaaS product may need serverless architecture and automated deployments, while an established enterprise platform may require decomposition of a monolith, database migration, containerization, or a gradual move from another cloud. The companies below cover different parts of that engineering spectrum, from application development and platform modernization to DevOps, data infrastructure, and long-term cloud operations.
1. OSKI Solutions
OSKI Solutions develops and modernizes applications on AWS, covering the software layer as well as the cloud infrastructure around it. Its AWS work includes serverless systems built with Lambda, API Gateway, Step Functions, SQS and DynamoDB, alongside containerized workloads running through ECS, Fargate and EKS. Managed databases, S3 storage, networking and content delivery can be incorporated into the same architecture.
Migration work is structured around staged cutovers rather than treating infrastructure transfer as an isolated deployment task. OSKI also works with infrastructure as code, CI/CD, monitoring, load testing, disaster recovery and cloud cost controls. This makes the company applicable to greenfield AWS applications as well as existing products that need re-platforming, higher release reliability or a more maintainable operational setup.
Key Highlights:
AWS architectures can combine serverless and container-based workloads within the same platform
Staged cutover planning for migrations involving live production systems
Infrastructure changes managed through repeatable code-based deployment
Monitoring, resilience and recovery considered during production architecture
Application engineering and cloud infrastructure handled within the same delivery scope

Conclusion
An AWS project should be scoped around the parts of the system that actually need engineering attention. A greenfield product may benefit from serverless functions, managed databases and event-driven architecture, while a mature platform could get more value from containerization, database modernization, Infrastructure as Code or decomposition of a tightly coupled application. Security, observability, release automation and recovery requirements also belong in the architecture discussion before development begins.
The shortlist should therefore be narrowed according to the intended workload rather than partner status or the breadth of a company's cloud catalogue alone. Technical discovery can establish whether the work calls for application developers, platform engineers, data specialists, DevOps expertise or a combination of these roles, making it easier to compare providers against a concrete AWS architecture and delivery scope.
