DevOps & Cloud Infrastructure

Always fast. Always online. Built for scale, reliability, and zero-downtime releases.

We design, automate, and maintain cloud infrastructures that run without failures — even under peak load. From CI/CD pipelines to observability and autoscaling, we make sure your systems stay stable, secure, and ready to grow.

What We Deliver

Cloud Architecture & Infrastructure Setup

Reliable foundations for any digital product.

  • scalable microservices architectures
  • production-ready Kubernetes clusters
  • load balancing & autoscaling
  • secure cloud networking
  • infrastructure-as-code (Terraform, Helm)
  • multi-region deployments

CI/CD Pipelines

Ship faster with automated, safe deployments.

  • Git-based workflows
  • build & test pipelines
  • environment promotion (dev → staging → prod)
  • automated rollbacks
  • blue/green & canary deployments

Monitoring & Observability

Know instantly when something breaks — or before it breaks.

  • real-time metrics
  • alerting & incident response
  • distributed tracing
  • log aggregation & analysis
  • performance monitoring for backend, frontend & infrastructure

Tools we use: Grafana, Prometheus, ELK Stack, Sentry, CloudWatch, Loki

High Availability & Reliability Engineering

Systems that stay online — even if parts fail.

  • redundancy & failover
  • zero-downtime maintenance
  • horizontal scaling
  • traffic shaping & resource optimization

Performance Optimization

We tune infrastructure to handle heavy load with fewer resources.

  • database query optimization
  • caching layers (Redis, CDN, edge networks)
  • JVM tuning
  • throughput tuning for Kafka & microservices

Security & Compliance

Secure by default.

  • secrets management
  • access control & IAM
  • vulnerability scanning
  • audit logs & compliance-ready setups

Problems We Solve

Teams come to us when:

  • infrastructure breaks under load
  • deployment process is slow and risky
  • outages and downtime hurt revenue
  • monitoring is missing or unreliable
  • scaling is manual and expensive
  • frontend, backend, and infra are not aligned
  • releases cause bugs in production
  • teams lack observability of system health

Frequently Asked Questions

How do you achieve zero-downtime deployments?

We use blue/green deployments, canary releases, and rolling updates in Kubernetes. Services are designed to be stateless, with database migrations that are backward-compatible. Load balancers route traffic gradually to new versions, and we monitor metrics to automatically roll back if issues are detected. This allows deployments even during peak traffic.

What monitoring and alerting do you set up?

We implement Prometheus for metrics collection, Grafana for visualization, ELK Stack for log aggregation, and Sentry for error tracking. We set up alerts for CPU, memory, disk usage, response times, error rates, and custom business metrics. Alerts are configured with appropriate thresholds and escalation paths to ensure issues are caught before they impact users.

How do you handle autoscaling for traffic spikes?

We configure Kubernetes Horizontal Pod Autoscaler (HPA) based on CPU, memory, and custom metrics (request rate, queue depth). We also use cluster autoscaling to add nodes when needed. For databases, we use read replicas and connection pooling. Load testing validates that autoscaling triggers correctly and systems handle expected traffic spikes.

Can you migrate from legacy infrastructure to cloud?

Yes. We assess current infrastructure, identify dependencies, plan migration strategy (lift-and-shift vs. refactor), and execute with minimal downtime. We containerize applications, set up CI/CD pipelines, implement monitoring, and gradually migrate services. Many teams migrate incrementally, moving non-critical services first to validate the approach.
