Cloud Infrastructure
Cloud Networking & VPC Design
Your cloud network architecture determines security boundaries, availability, cost efficiency, and connectivity for every resource you deploy. We design and implement VPC architectures with proper subnet segmentation, routing tables, NAT configuration, DNS resolution, VPN connectivity, and firewall rules — the networking foundation your infrastructure deserves.

We implement, you ship. Async, documented, done in days.
What We Deliver
A production-grade VPC architecture with CIDR planning, public/private/data subnet tiers across multiple availability zones, route tables and NAT gateways, security groups and network ACLs, VPC peering or Transit Gateway for multi-VPC connectivity, private DNS zones, and VPN or interconnect for hybrid connectivity. All defined in Terraform.
CIDR Planning
Proper CIDR allocation prevents painful re-networking later. We plan address spaces that accommodate growth, avoid overlaps with on-premises or peered networks, and leave room for additional subnets. Each subnet tier gets a predictable CIDR range — /20 or /21 per AZ for workloads, /24 for management subnets, /28 for NAT and firewall subnets.
Subnet Architecture
Public subnets host load balancers and bastion hosts with internet gateway routing. Private subnets run application workloads with NAT gateway routing for outbound internet access. Data subnets isolate databases and caches with no internet routing. Each tier spans multiple availability zones for high availability.
Security & Traffic Control
Security groups provide stateful firewall rules at the instance/ENI level. Network ACLs add stateless rules at the subnet level for defense in depth. VPC flow logs capture traffic metadata for analysis and compliance. We implement explicit deny rules and justify every allow rule in documentation.
Multi-VPC & Hybrid Connectivity
For multi-environment or multi-team architectures, we configure VPC peering, Transit Gateway (AWS), Shared VPC (GCP), or Virtual Network peering (Azure). Site-to-site VPN connects on-premises networks. Private DNS zones enable service discovery across VPCs. Transit Gateway route tables control which VPCs can communicate.
