Managing Disk Volumes, Networks, and Subnets in QuickInfra

Networking and storage are the parts of cloud infrastructure that engineers tend to set up once and never look at again — until something breaks. QuickInfra treats networks, subnets, and disk volumes as managed resources with full visibility and lifecycle control.

Networks (VPCs)

The Networks section under Manage shows all VPCs across your connected cloud accounts. Each network entry displays the CIDR block, region, account, and which QuickInfra projects are using it. You can create new VPCs directly from the console — specify the CIDR range, enable DNS hostnames, and configure internet gateway attachment.

For teams using the recommended multi-account architecture, you'll typically have one VPC per environment per account. QuickInfra's cross-account network view makes it easy to verify that your CIDR ranges don't overlap — a common mistake when multiple environments are set up independently.

Subnets

Subnets in AWS determine the availability zone placement and routing behaviour of your instances. The Subnets view shows all subnets across accounts, their associated VPC, AZ, CIDR, and whether they're public or private. A well-structured subnet layout — public subnets for load balancers and NAT gateways, private subnets for application servers, isolated subnets for databases — is a prerequisite for production-grade security.

QuickInfra's Infrastructure Templates include a standard three-tier subnet layout that follows AWS best practices out of the box.

Disk Volumes (EBS)

The Disk Volumes section lists all EBS volumes across your accounts. Each entry shows the volume type (gp3, io2, sc1), size, IOPS, throughput, current state, and which instance it's attached to. Unattached volumes — which still incur cost — are flagged prominently.

From the Disk Volumes view you can create new volumes, attach or detach them from instances, create snapshots, and delete volumes you no longer need. Snapshot creation is logged with the user and timestamp — useful for audit trails in environments where storage changes need to be documented.

Volume Snapshots and Backup

QuickInfra supports scheduled EBS snapshots as a Custom Script attachment. A nightly snapshot of your production database volumes, retained for 30 days, gives you point-in-time recovery without a separate backup tool.

Cross-AZ Considerations

EBS volumes are AZ-scoped — a volume in ap-south-1a cannot be directly attached to an instance in ap-south-1b. QuickInfra's Disk Volumes view makes this explicit, showing the AZ for every volume alongside the AZ of attached instances. Mismatched AZ configurations are flagged as warnings, catching a class of misconfiguration that can cause availability issues.
