Architecture & Resilience
Design systems that withstand failures and scale seamlessly under variable loads. CloudNexus infrastructure is built for high availability, but your application architecture must complement it.
- Deploy across multiple Availability Zones (AZs) to eliminate single points of failure
- Use stateless application servers behind CloudNexus Load Balancers
- Implement database read replicas for traffic distribution and failover
- Separate compute, storage, and database tiers to scale independently
Pro Tip
Enable Auto-Scaling Groups with a target CPU utilization of 60-70%. This buffers against traffic spikes while preventing unnecessary scaling events.
resource "cloudnexus_autoscaling_group" "web" {
name = "production-web-cluster"
min_size = 2
max_size = 12
desired_capacity = 3
availability_zones = ["us-east-1a", "us-east-1b"]
health_check_type = "ELB"
}Security & Compliance
Security should be baked into your infrastructure from day one. Follow the principle of least privilege and defense-in-depth.
- Enforce IAM roles with scoped permissions; avoid long-lived access keys
- Isolate workloads using VPCs, subnets, and security groups
- Enable encryption at rest (AES-256) and in transit (TLS 1.3)
- Place Web Application Firewall (WAF) rules in front of public endpoints
Security Warning
Never store secrets in environment variables or version control. Use CloudNexus Secret Manager or HashiCorp Vault for dynamic credential injection.
Performance Optimization
Latency kills conversion. Optimize your stack end-to-end using caching, edge computing, and connection pooling.
- Serve static assets via CloudNexus CDN with cache-control headers
- Use Redis or Memcached for session storage and frequent query caching
- Implement database connection pooling (PgBouncer/ProxySQL)
- Compress payloads with gzip/brotli and minify front-end assets
server {
listen 443 ssl;
ssl_protocols TLSv1.3;
gzip on;
gzip_types text/css application/javascript image/svg+xml;
# Cache static assets for 1 year
location ~* \.(jpg|jpeg|png|gif|ico|css|js)$ {
expires 365d;
add_header Cache-Control "public, immutable";
}
}Cost Management
Cloud efficiency is continuous. Right-size resources, eliminate waste, and leverage committed pricing.
- Audit idle instances, unattached volumes, and orphaned snapshots weekly
- Use reserved instances for steady-state workloads (up to 40% savings)
- Implement storage lifecycle policies to archive cold data to Glacier
- Set budget alerts at 60%, 80%, and 100% of forecasted spend
Optimization Insight
Right-sizing often yields the highest ROI. Use CloudNexus Performance Insights to identify underutilized instances and step down to the next tier.
Monitoring & Observability
You can't fix what you can't measure. Implement the three pillars: metrics, logs, and traces.
- Configure centralized logging with structured JSON format
- Set up distributed tracing for microservice request flows
- Define SLOs and alert on error budget burn rates, not just thresholds
- Run synthetic health checks every 30 seconds across regions
Deployment & CI/CD
Automate deployments to reduce human error and accelerate release cycles. Treat infrastructure as code.
- Use Terraform or Pulumi for reproducible infrastructure provisioning
- Adopt blue/green or canary deployments for zero-downtime releases
- Enforce pipeline gates: lint â unit tests â security scan â staging deploy
- Automate rollbacks on health check failures or elevated error rates
Deployment Strategy
Combine CloudNexus Kubernetes with ArgoCD for GitOps. Your cluster state always matches your repository, enabling safe drift detection and automatic reconciliation.
