Extending a Low-Code Tool with Multi-cloud Deployment Capabilities

Low-code emerged as an evolution of model-driven engineering to accelerate software delivery, and it continues to gain traction today. However, low-code tools and solutions have primarily focused on development, often neglecting or offering minimal support for the application deployment process, such as lacking capabilities for multi-cloud deployments. In this paper, we propose an extension of BESSER, an open-source low-code platform, to address the packaging and deployment of applications in multi-cloud environments. This extension includes the definition of a language and a grammar to enable the modeling of the deployment architecture, also enabling the specification of public and on-premises clusters. Additionally, we have developed code generators to automate the application packaging, and cloud provisioning and deployment using Terraform. The complete infrastructure is available in an open-source repository.
