Backend Capability Matrix

Backend & Cloud Capabilities

Distributed Microservices & gRPC

Decoupled, high-throughput microservices communicating over gRPC, Protocol Buffers, and REST APIs for sub-millisecond inter-service latency.

  • High-concurrency Go & Node.js Services
  • gRPC & Protobuf Binary Serialization
  • API Gateway Routing & Rate Limiting

Database Optimization & Caching

PostgreSQL query optimization, Redis multi-layer caching, connection pooling, and automated database sharding for heavy read/write workloads. Feed your data into enterprise AI agents and RAG systems.

  • PostgreSQL Master-Replica Clusters
  • Redis Cluster Cache Invalidation
  • 📊 TimescaleDB & ClickHouse Analytics

DevOps & Kubernetes Infrastructure

Automated Terraform IaC, Docker containerization, Kubernetes autoscaling (KEDA), and continuous GitHub Actions zero-downtime deployment pipelines. Run high-performance web platforms on top of it.

  • ☁️ AWS EKS / GCP Kubernetes Autoscaling
  • 🛠️ Terraform Infrastructure as Code
  • Zero-Downtime Blue-Green Deployments

The ZAVA Advantage

Monolithic Legacy Backend vs. ZAVA Microservices

Why enterprise platforms trust ZAVA for high-concurrency cloud systems.

Infrastructure Metric Legacy Monolithic API ZAVA Distributed Microservices
Peak Concurrency Capacity ✖ Bottlenecked (< 2,000 req/sec) ✔ 50,000+ Req/Sec Auto-Scaling Go/Node
API Response Latency ✖ 250ms - 800ms Laggy REST ✔ < 15ms Sub-ms gRPC Protobuf Streams
System Reliability & Uptime ✖ Frequent Outages Single Node ✔ 99.99% SLA Multi-Region Active Cluster
Deployment Risk ✖ Single Point Failure Monolith ✔ Zero-Downtime Blue-Green K8s Rollout
Database Performance ✖ Lock & Slow Queries Single DB ✔ Postgres Sharding Redis Cluster Cache

Answers

Frequently Asked Questions

When should a business migrate from a monolith to microservices? +
Microservices are recommended when engineering teams grow, deployments become bottlenecked, or specific components require independent horizontal scaling. We perform a thorough cost-benefit analysis before recommending microservice decomposition.
What cloud providers do you support for Kubernetes hosting? +
We engineer multi-cloud Terraform setups targeting AWS (EKS), Google Cloud (GKE), Microsoft Azure (AKS), DigitalOcean Kubernetes, or hybrid on-premise Kubernetes clusters.
How do you handle database failover and data integrity? +
We implement PostgreSQL automated failover with Patroni/PgBouncer, asynchronous cross-region replication, distributed ACID transactions, and daily automated encrypted backups.
