Technologies

This section outlines the hardware, software, and communication technologies powering Athena SMS.

1. Hardware Technologies

  • Cloud Servers: Auto-scalable, high-availability servers.

  • Database Clusters: Sharded MongoDB clusters.

  • Load Balancers: Ensures uptime and optimized performance.

  • Containers & Orchestration: Docker + Kubernetes.

  • In-Memory Storage: Redis for fast data access.

2. Software Technologies

  • Frontend: Built with Next.js supporting SSR/CSR.

  • Backend: Microservices in NestJS, communicates via gRPC.

  • Database: MongoDB with tenant-wise isolation.

  • Auth & Security: JWT, RBAC, encryption.

  • Message Queues: RabbitMQ for async processes.

  • Caching: Redis for sessions and quick retrievals.

3. Communication Technologies

  • RESTful APIs for client-server interaction.

  • WebSockets for real-time updates.

  • RabbitMQ events for background task handling.

4. DevOps & Infrastructure Stack

  • CI/CD Tools: GitLab Actions

  • Monitoring: Prometheus, Grafana

  • Logging: ELK Stack (Elasticsearch, Logstash, Kibana)

  • Infrastructure as Code: Terraform or Helm for Kubernetes deployments

5. Security Mechanisms

  • HTTPS with SSL

  • Token expiration and refresh policies

  • IP-based rate limiting

  • Audit logs to track user/system actions

  • Data encryption at rest (MongoDB) and in transit (TLS)

6. Performance & Scalability

  • Auto-scaling via Kubernetes HPA (Horizontal Pod Autoscaler)

  • Redis caching to reduce DB hits

  • Load-balanced API Gateway

  • Sharded databases for horizontal scaling
