Building a Multi-Tenant MRP System on Kubernetes and FastAPI

Building a Multi-Tenant MRP System on Kubernetes and FastAPI


In today's highly competitive business environment, companies need to be able to respond quickly and efficiently to changes in demand and supply. One key way to do this is through the use of Material Resource Planning (MRP) systems, which help organizations plan and manage their production processes, inventory levels, and other resources.

However, traditional MRP systems can be expensive and complex to implement, especially for small and medium-sized enterprises (SMEs). This is the challenge that we had to solve for our clients. We have developed a cutting-edge MRP system that runs on the Kubernetes platform and uses FastAPI and Postgres to deliver a scalable, secure, and easy-to-use solution for SMEs.


At Nebula Cloud Solutions, we specialize in building cloud-native applications that help businesses optimize their operations. Our team has extensive experience in developing and deploying applications on Kubernetes, and we saw an opportunity to create a new MRP system that could take advantage of the platform's scalability, reliability, and security features.

We decided to build the system using FastAPI, a high-performance web framework that makes it easy to create APIs and microservices. This allowed us to create a flexible and modular system that could be easily extended and customized for different customers. We also chose Postgres as the database engine, as it is well-suited for high-volume data processing and has strong support for multi-tenancy.


One of the main challenges we faced was how to design the system in a way that would allow multiple companies (tenants) to use it simultaneously while keeping their data isolated from each other. This is known as "multi-tenancy" and it is a critical requirement for many enterprise applications.

To solve this problem, we implemented a series of measures to ensure that each tenant's data is securely isolated from the others. These included:

  • Using separate Postgres schemas for each tenant, to ensure that data is stored in separate tables and cannot be accessed by other tenants.
  • Implementing role-based access control (RBAC) to allow administrators to control which users have access to which resources. This ensures that users can only see and modify the data that they are authorized to access.
  • Implementing encryption at rest to protect data from unauthorized access when it is stored on disk.
  • Monitoring and logging system access and events to detect and prevent unauthorized access and activities


To build our MRP system, we used the following technologies and tools:

  • Kubernetes: We used Kubernetes as the underlying platform for our MRP system. This allowed us to take advantage of its scalability, reliability, and security features, as well as its ability to run on a variety of cloud providers and on-premises environments.
  • FastAPI: We used FastAPI to build the system's APIs and microservices. This allowed us to create a high-performance, easy-to-use system that could be easily extended and customized for different customers.
  • Postgres: We used Postgres as the database engine for our MRP system. This allowed us to take advantage of its powerful data processing capabilities and its support for multi-tenancy.
  • Other tools and technologies: We also used a variety of other tools and technologies, such as Docker for containerization, Helm for deployment, and Prometheus for monitoring and logging.


The MRP system we developed using Kubernetes, FastAPI, and Postgres has been a success. It has helped our customers to improve their production processes, reduce inventory costs, and increase efficiency. Some of the key benefits of our system include:

  • Scalability: The system can easily be scaled up or down to meet the changing needs of our customers.
  • Reliability: The system is highly reliable, with minimal downtime and no data loss.
  • Security: The system is secure, with data isolation and encryption at rest to protect against unauthorized access.
  • Ease of use: The system is easy to use, with a user-friendly interface and clear documentation.
  • Customization: The system can be easily customized for different customers, with flexible APIs and configurable settings.


In conclusion, our team at Nebula Cloud Solutions has successfully built a cutting-edge MRP system using Kubernetes, FastAPI, and Postgres. This system has helped our customers to improve their operations and become more competitive in today's market. We are proud of the work we have done and are excited to continue delivering innovative solutions to our customers.
