AWS Cloud Setup in Greater Noida

A two- or three-zone VPC supports most workloads. Public subnets hold the load balancer; private subnets hold the application and database; outbound traffic uses a NAT gateway or an endpoint.

Campus and plant systems often integrate with payment, messaging, identity and document services. Restrict egress to those endpoints instead of allowing every destination.

Keep a clear diagram of what is public and what is private. A new vendor should be able to understand it without a call.

Backups need a retention rule and a restore test. For a campus system, the test should include admission and fee records; for a plant system, production and dispatch records.

Root access is for recovery only. Staff use roles with MFA, and the deployment role is separate from the database administration role.

Mark the peak weeks in the account calendar. A production change during admissions or a campaign should require a higher approval, and the budget alerts should be reviewed before the peak.

CloudTrail, Config and flow logs provide the evidence layer. Store them separately with limited delete access.

Tag resources by department, environment and owner. A campus or plant budget is easier to defend when the bill can be split by department.

Set separate budgets for production and non-production. A test environment that runs through the quiet months is a common source of waste.

The handover covers the account map, network diagram, IAM roles, backup schedule, restore steps, budget owners and the peak-week freeze procedure.

It also records what is not included: application migration, code changes, database tuning and 24x7 operations.

Moving the campus or plant application, changing code, tuning queries and running the system day to day are separate. The setup creates the landing space and guardrails.

The provider bills AWS usage, support plans and third-party licences separately.
