Cloud-native Java application development

Our Java developers can deliver containerized applications based on microservices architecture and running under the Kubernetes orchestrator. These applications are cloud-agnostic and run on any public cloud (AWS, Azure, Google Cloud Platform, etc.) supported by Kubernetes or on private hardware. In the development of our cloud-native applications, we adhere to the principles, practices and tools defined by Cloud Native Computing Foundation (CNCF).

Cloud-only Java application development

Our Java developers can build Java applications based on serverless architecture for cloud-only hosting. Such applications allow you to derive specific benefits from a cloud vendor’s services, e.g., the pay-as-you-go service, and don’t require any container/hardware provisioning and management.
