Reactjs – Is next used as fullstack scalable with kubernetes deployment?

I am trying to setup a frontend with nextjs and spring boot as backend for one of the internal products of my company. My colleague suggested to look into nextjs as for backend as well.

SSO will be used as authentication for the product and ingress will be used as load balancer between kubernetes nodes (Atleast 3 nodes), with mysql as database with galera cluster (2 nodes atleast for database).

Will this setup work if I use nextjs as a fullstack framework?

Currently have implemented frontend side of it and tried to host it. It was successful.

Nextjs version: 14.0.4

    Using Next.js as a full-stack framework for both frontend and backend is certainly possible, but it’s important to clarify some aspects of your proposed architecture.

    1. Next.js as Full-Stack Framework:

      • Next.js is primarily designed as a frontend framework, but with the introduction of API Routes, you can create backend functionality within your Next.js application. This can be useful for building lightweight backend services.

    2. Spring Boot as Backend:

      • If you’re planning to use Next.js as a full-stack framework, you might not need Spring Boot for the backend. Instead, you can utilize Next.js API Routes for serverless backend functions. However, if you have specific requirements that Spring Boot fulfills or if you want a more traditional RESTful backend, you can keep it.

    3. SSO for Authentication:

      • Ensure that your SSO implementation aligns well with both the frontend and backend. Next.js can integrate with various authentication providers, and Spring Boot can handle authentication separately. Make sure they work seamlessly with your chosen SSO solution.

    4. Ingress and Load Balancing:

      • Kubernetes Ingress is a good choice for load balancing between nodes. Ensure that your Next.js application and Spring Boot backend can handle traffic correctly when distributed across multiple nodes.

    5. MySQL with Galera Cluster:

      • Using MySQL with Galera Cluster is a good choice for achieving high availability. Make sure your database connection setup in both the frontend and backend is configured to work with a Galera Cluster.

    6. Version Compatibility:

      • Ensure that the versions of Next.js, Spring Boot, and other dependencies are compatible with each other. Your Next.js version (14.0.4) should work well, but verify that it’s compatible with the dependencies you’re using.

    7. Deployment and Scaling:

      • Consider how you will deploy and scale your application. Tools like Docker and Kubernetes can help with containerization and orchestration. Ensure that your deployment strategy accounts for both frontend and backend components.

    8. Monitoring and Logging:

      • Implement proper monitoring and logging for both frontend and backend components. This is crucial for identifying and resolving issues in a distributed system.

    In summary, using Next.js as a full-stack framework is possible, but you need to carefully plan and ensure that each component (frontend, backend, database, SSO, load balancing) is integrated and configured correctly. Test thoroughly, especially in a Kubernetes environment, to make sure the setup is robust and scalable.

    Microservices architecture involves breaking down a software application into smaller, independently deployable services. This architecture is preferred for its scalability, flexibility, and ability to use different technologies for different services.

    If you implement an authentication service within next.js, this setup will be bad because if your next.js pod goes down, you will lose two services, authentication and front-end service.

    If you want to use the next.js for its server-side-rendering benefit for the client, you have to be careful where you make requests. if you are on the server your request URL will be different and it will need extra configuration
