BYOC Testing for Regulated Industries

What is BYOC testing for compliance?

BYOC (Bring Your Own Cloud) testing for compliance means running distributed Playwright tests on infrastructure you own and control, so that test artifacts — traces, screenshots, network recordings, and DOM snapshots — never leave your organization's cloud boundary.

TraceLoom deploys a lightweight data plane (EC2 Spot instances, S3 bucket, SQS queue) inside your AWS account via a single CloudFormation stack. Your Playwright tests execute on your EC2 instances, and every .trace.zip is written directly to your S3 bucket. TraceLoom's SaaS control plane orchestrates the work — scheduling, sharding, notifications — but only receives run metadata: test names, pass/fail counts, and timing.

This matters for teams operating under SOC 2, HIPAA, FedRAMP, GDPR, or internal data residency policies. When your compliance officer asks "where does the test data go?" the answer is: your AWS account, your region, your encryption keys, your access controls.

Why managed testing platforms fail compliance reviews

Managed testing platforms like BrowserStack and Sauce Labs run your tests on their infrastructure. That means your Playwright traces — containing DOM snapshots, network request/response data, console logs, and full-page screenshots — are stored on vendor servers outside your security boundary.

For engineering teams in regulated industries, this creates three specific compliance gaps:

• 1. Test data contains sensitive information. E2E tests interact with staging environments that mirror production data structures. Playwright traces capture DOM state, API responses, cookies, and local storage — potentially including PII, PHI, or financial data that your compliance framework prohibits sending to third parties.
• 2. Data residency is uncontrollable. Managed platforms choose where your data is processed and stored. If your organization requires data to stay in a specific AWS region (e.g., us-east-1 for FedRAMP, eu-west-1 for GDPR), a vendor-hosted platform can't guarantee that your Playwright trace files will comply.
• 3. Vendor access is a risk vector. When a vendor stores your test artifacts, their employees and systems have potential access to that data. Each additional vendor with data access expands your attack surface and complicates SOC 2 Type II audit scope — additional vendor questionnaires, subprocessor reviews, and BAAs to maintain.

How TraceLoom solves compliance for Playwright testing

TraceLoom's BYOC architecture eliminates the compliance gap by separating orchestration from execution. TraceLoom's control plane handles scheduling, sharding, and the dashboard — your AWS account handles all compute and storage. The architectural boundary is enforced via a cross-account IAM role with scoped permissions.

TraceLoom deploys a single CloudFormation stack in your AWS account. The stack creates an S3 bucket for traces, an SQS queue for test dispatch, EC2 launch configuration for Spot workers, and an IAM role for cross-account access. All resources are created in the AWS region you specify. Deployment typically completes in under 15 minutes — TraceLoom internal testing, March 2026.

Every Playwright test produces a full .trace.zip file — DOM snapshots, network requests, console logs, screenshots — written directly to your S3 bucket by your EC2 instances. TraceLoom's control plane never touches these files. The control plane receives a metadata callback with run status (pass/fail, timing, test names) and nothing else.

If your security team needs to disconnect TraceLoom, they revoke the IAM role. Your infrastructure, traces, and data remain in your AWS account. There is no vendor lock-in on the data plane — the CloudFormation stack is yours to keep, modify, or delete.
