Deployment Architecture and Scalability

DAKSH is designed for scalable, secure, and highly modular deployment across diverse environments — from cloud-native infrastructures to edge devices and private data centers. Its serverless-first design philosophy minimizes operational overhead while ensuring elastic resource usage, automated failure recovery, and seamless horizontal scaling. Whether deployed in a Smart City dashboard, an enterprise CRM, or a kiosk-based citizen service portal, DAKSH remains performant, responsive, and resource-efficient.

1. Modular Cloud-Native Architecture

At its core, DAKSH is orchestrated using a microservices-based, event-driven architecture. The system is split into independent functional layers — including input processing, embedding search, inference, speech handling, and response rendering — each of which can be deployed independently or as part of a monolithic flow.

The default deployment stack leverages AWS services, including:

  • API Gateway: Entry point for all text/voice queries, with built-in throttling, request validation, and CORS support.

  • Lambda Functions: Stateless compute containers handle preprocessing, context assembly, embedding search, and model inference. This ensures scalability without persistent infrastructure.

  • S3 Buckets: Store uploaded knowledgebase files and their corresponding processed chunks, with versioning enabled for rollback and audits.

  • RDS or DynamoDB: Metadata store for user sessions, audit logs, schema references, and knowledgebase mappings.

  • FAISS (via containerized service) or Pinecone: High-performance vector search engine for retrieval-augmented generation.

  • CloudWatch and Prometheus: Logging, tracing, and metrics aggregation to monitor latency, usage trends, and performance bottlenecks.

All services are container-friendly, allowing easy deployment via Docker, Kubernetes, or ECS in private or hybrid cloud environments.


2. Serverless and Auto-Scaling Characteristics

DAKSH leverages serverless compute (AWS Lambda or equivalent) for most components, including:

  • Query preprocessing and language detection

  • Embedding vectorization

  • Retrieval orchestration

  • Response generation

  • Audit logging and session state handling

Each Lambda function is invoked on demand, scales instantly with concurrent queries, and terminates after task completion — ensuring cost-efficiency and horizontal elasticity. There are no idle resource costs, making this design particularly well-suited for citizen services and seasonal query spikes.

In high-traffic settings, provisioned concurrency and event queues (like AWS SQS or Kafka) are used to prevent cold starts and provide predictable latency.


3. Deployment Models

DAKSH supports multiple deployment strategies to fit diverse operational contexts:

  • Public Cloud (Multi-Tenant): SaaS model where tenants access the platform via subdomains or APIs. Tenant isolation is enforced through scoped IAM and virtual vector indexes.

  • Private Cloud (Single-Tenant): For large organizations requiring dedicated resources, DAKSH can be deployed as a fully managed stack in a customer’s AWS/GCP/Azure account.

  • Hybrid On-Prem + Cloud: Embedding and vector search operate on-premise while inference runs in the cloud — ideal for compliance-sensitive sectors (e.g., healthcare, defense).

  • Edge/Kiosk Deployment: Light-weight variant of DAKSH with offline STT/TTS support and cached Q&A capabilities, suitable for voice kiosks in low-connectivity areas.

Each model includes automated provisioning scripts, CI/CD hooks via GitHub Actions or AWS CodePipeline, and Helm charts for Kubernetes-based clusters.


4. Scalability Benchmarks

DAKSH has been benchmarked for both latency and throughput under varied deployment modes:

Metric

Lambda-Based Cloud

GPU-Backed Inference

Edge Device (Offline)

Median Response Time

400–600 ms

200–350 ms

700–900 ms

Max Concurrent Sessions

5000+ (auto-scale)

1500+

1–5 simultaneous users

Cold Start Recovery

~1.2 seconds

~0.5 seconds

Not applicable

Monthly Cost (100k queries)

<$150 (Lambda)

~$400 (GPU)

Minimal (device-local)

Vector search latency remains under 100ms for ~1M documents using FAISS or Pinecone, and caching accelerates repeated queries or similar intent clusters.


5. DevOps and Monitoring

DAKSH offers a fully observable deployment experience:

  • Grafana dashboards: For real-time traffic, error rates, retrieval time, and TTS latency.

  • Prometheus alerts: For anomalous spikes in usage or inference failures.

  • Slack/Webhook Integrations: For notifying DevOps teams on deployment errors or usage threshold breaches.

  • Versioned Model Registry: Ensures backward-compatible model upgrades and A/B testing.

Automated deployments are supported via:

  • GitOps workflows with rollback capability

  • Staging and production environment separation

  • Canary and blue-green deployment pipelines for zero-downtime model updates
