Cuenca del Plata is a prominent organization in water resource management in the region, committed to sustainability and optimizing the use of aquatic resources. Covering an area of 3,100,000 km², it is the fifth-largest river basin in the world. Together with the OAS, they play a crucial role in monitoring and managing water resources, ensuring their efficient and sustainable use for various applications, from water supply to natural disaster prevention.
The client faced the challenge of modernizing and improving the efficiency of their hydrometeorological data management system. The on-premise infrastructure used to operate Deltares’ Delft FEWS system no longer met the growing needs for scalability, availability, and performance. It was imperative to migrate to a cloud solution that could handle large volumes of real-time data, improve decision-making, and ensure operational continuity.
Therefore, DirMOD was tasked with designing and deploying a cloud infrastructure specifically to host the application, ensuring compliance with the highest standards of security, availability, and performance.

DirMOD deployed various key AWS tools to meet Cuenca del Plata‘s migration requirements. This included implementing EC2 instances to host the application’s operating system, a NAT Gateway to ensure a secure internet connection, S3 as an efficient storage solution for application data, and an ALB load balancer to maintain high availability and optimal load distribution among instances.
EC2 provides scalable computing capacity in the cloud, while the NAT Gateway ensures secure communication with external users. S3 offers secure and scalable storage for application data. The ALB load balancer efficiently distributes network traffic among instances, thus improving system availability and fault tolerance.
Additionally, Terraform was used for efficient infrastructure management as code, ensuring consistent and repeatable deployment, facilitating efficient management of AWS resources.
Thanks to the designed infrastructure, Cuenca del Plata was able to benefit from the scalability, availability, and performance advantages provided by AWS, establishing a solid foundation for future expansions and improvements in their flood forecasting and control system.
