Cloud Infrastructure & DevOps
End-to-end cloud infrastructure automation on AWS using Terraform and Ansible — delivering secure, highly available, multi-environment deployments with infrastructure-as-code governance.
Why Choose Cloud Infrastructure & DevOps?
Infrastructure as Code
Fully automated provisioning with Terraform and Ansible eliminates manual configuration drift and enables repeatable, version-controlled deployments.
High Availability by Design
Multi-AZ deployments across three availability zones ensure resilience against zone failures with no single point of failure.
Security-First Architecture
Private subnets, no public IPs, IAM role-based access, encrypted EBS volumes, and SSM-only remote access replace legacy SSH key management.
Multi-Environment Support
Pre-configured dev, staging, and production profiles with environment-specific instance types, storage sizes, and access controls.
Cost-Optimised Resources
Right-sized instances per environment (t3.xlarge for dev/staging, r5.xlarge for prod) with lifecycle-managed S3 storage and gp3 EBS volumes.
Cross-VPC Connectivity
Automated VPC peering with DNS resolution, route table management, and security group ingress rules for seamless cross-region application integration.
Core Features
VPC & Networking
Custom VPCs with private subnets, NAT Gateway, Internet Gateway, and VPC endpoints for SSM and S3
Compute & Storage
EC2 instances with dedicated EBS data volumes, configurable instance types, and encrypted gp3 storage
IAM & Access Control
IAM roles, instance profiles, and Systems Manager (SSM) for secure, keyless remote access
Internal DNS Management
Route53 private hosted zones with per-node DNS records for service-to-service discovery
Remote State Management
Encrypted S3 backend for Terraform state with full audit history and team collaboration support
VPC Peering & Integration
