This cloud-native web application is built using a mix of technologies. It's designed to be accessible to users via the internet, allowing them to vote for their preferred programming language out of six choices: C#, Python, JavaScript, Go, Java, and NodeJS.
Frontend: The frontend of this application is built using React and JavaScript. It provides a responsive and user-friendly interface for casting votes.
Backend and API: The backend of this application is powered by Go (Golang). It serves as the API handling user voting requests. MongoDB is used as the database backend, configured with a replica set for data redundancy and high availability.
To deploy and manage this application effectively, we leverage Kubernetes and a variety of its resources:
Namespace: Kubernetes namespaces are utilized to create isolated environments for different components of the application, ensuring separation and organization.
Secret: Kubernetes secrets store sensitive information, such as API keys or credentials, required by the application securely.
Deployment: Kubernetes deployments define how many instances of the application should run and provide instructions for updates and scaling.
Service: Kubernetes services ensure that users can access the application by directing incoming traffic to the appropriate instances.
StatefulSet: For components requiring statefulness, such as the MongoDB replica set, Kubernetes StatefulSets are employed to maintain order and unique identities.
PersistentVolume and PersistentVolumeClaim: These Kubernetes resources manage the storage required for the application, ensuring data persistence and scalability.
