Getting an AWS POC Sandbox

Part of NUHS Commercial Cloud. Sandbox portal: for.sg/nuhs-poc-sandbox · Acceptable Use Policy: for.sg/nuhs-cloud-aup

What you get

Your own temporary AWS account — isolated, pre-approved, and paid for by the programme — to test ideas, evaluate AWS services, or learn the cloud. It comes with a fixed budget and end date, and everything in it is permanently wiped when the lease ends.

How to get your sandbox — three steps

Step 1 · Register your login (once only)

Submit the registration form at for.sg/nuhs-cloud-sso with your own @nuhs.edu.sg address: verify your email with the one-time code, tick the declaration and submit. Your login is created automatically and you get a welcome e-mail from sso@nuhs.cloud within a few minutes. Each person registers their own login. Already have one? Skip to Step 2.

The registration form: the not-an-HCC-account notice, the NUHS email field with Verify, and the declaration checkbox

Then activate your login at the AWS access portal, for.sg/nuhs-cloud-login: enter your e-mail and choose Next, enter the one-time code AWS e-mails you (from no-reply@signin.aws), scan the QR code with an authenticator app (Microsoft Authenticator, Google Authenticator, Duo or Authy), then set your password. This only happens once.

Step 2 · Request a sandbox

Open the sandbox portal at for.sg/nuhs-poc-sandbox — you're signed in straight away with the same login. Choose Request lease, pick Individual Learner or Project POC, describe what you'll test and why, and accept the terms of use. An Individual Learner account is ready in minutes; a Project POC request is reviewed by the GITO Cloud team and you're notified by e-mail.

Step 3 · Open your AWS account

When your lease shows as Active on the portal home page, choose Login. The AWS console of your sandbox account opens.

Before you build anything, switch the console region (top right) to Asia Pacific (Singapore) ap-southeast-1. It's the only region allowed; anything you try to create in another region is blocked and looks like a permissions error.

One login, several systems: the same login also signs you in to other NUHS Commercial Cloud systems, listed at for.sg/nuhs-commercial-cloud. You don't need to register separately for each one.
Sign-in tip: if you ever see "Sign-in failed: Timed out waiting for sign-in to complete", choose Clear session and try again, or open for.sg/nuhs-poc-sandbox again.

While you work — know what each budget alert means

Budget reachedWhat happens
50%E-mail alert only. Nothing changes — just a heads-up.
75%E-mail alert only. Time to start wrapping up or plan to export your work.
90%E-mail alert: your last warning. Your account still works, but export anything you want to keep now, and ask the GITO Cloud team before it runs out if you need more budget.
100%All resources are PERMANENTLY DELETED. This is automatic and irreversible — nothing survives, no snapshots, no exceptions.

Your end date works the same way: you get reminder e-mails 7 days and 1 day before it, and on the end date the account is wiped.

90% is your last real warning. Nothing is frozen or blocked before the end — the account keeps working until spend reaches 100% or the end date arrives, and then everything is deleted automatically. AWS cost data can lag by up to a day, so don't leave it to the last moment.
Before your lease ends, export what you want to keep: push code to your repo, save CloudFormation/Terraform templates, screenshot results, download datasets you generated. Nothing survives the clean-up — no snapshots, no S3 buckets, nothing.

The golden rules

Working as a team

A project team can work inside one sandbox account. One person (the lease owner) requests it; teammates are then added to that lease and get the same console access (they can't end the lease or change its budget or duration).

  1. Everyone gets a login. Each teammate who doesn't have one yet submits the SSO account registration form at for.sg/nuhs-cloud-sso with their own @nuhs.edu.sg address.
  2. Everyone activates. Each teammate follows their welcome e-mail to finish the one-time first sign-in. A brand-new login can take up to an hour to show up in search.
  3. The owner requests a Project POC lease at for.sg/nuhs-poc-sandbox and waits for approval.
  4. Once the lease is Active, open it (Leases → your lease) and go to the Assignments tab.
  5. Search for them by their @nuhs.edu.sg e-mail (or a whole Identity Center group, if everyone in it should have access) and choose Add.
  6. Choose Save changes. Their status moves from Pending to Active, and they get an e-mail once access is live.

Once added, they'll see your account under a "Shared with me" view when they log in, and can access it the same way you do. (If your lease is on the Individual Learner template, sharing isn't available — that account stays yours alone.)

A shared account is still one budget and one end date, shared by everyone with access — plan accordingly, and make sure everyone on the team knows the same golden rules apply.

Need more time or budget?

It depends on whether your lease has already expired:

Either way, ending or losing a lease does not delete your login — you keep the same Identity Center account and can request a new lease whenever you need one.
