WiserReview runs as a distributed microservices platform on Microsoft Azure, fronted by Cloudflare's global edge network. Each service is independently deployed, auto-scaled, and monitored.

System Architecture
Complete view of the WiserReview platform showing all services, security zones, and data flow. All external traffic is filtered through Cloudflare before reaching Azure-hosted application services. The data zone is completely private with no public endpoints.
All traffic enters through Cloudflare before reaching Azure-hosted services. The data zone has no public endpoints and is accessible only via IP whitelist.
Data Ingestion & Review Display
Reviews, orders, and product data enter WiserReview through four distinct channels. Every path is authenticated and encrypted. All data is validated, sanitized, and stored with tenant-level isolation.
All data enters through authenticated, encrypted channels. All stored data is AES-256 encrypted at rest and workspace-scoped.
Multi-Tenant Data Isolation
Every request carries a unique Tenant ID, extracted from the authenticated token (merchant app) or embedded in the widget script (storefront). All database queries, cache entries, and media storage are scoped to that tenant. No merchant can access another merchant's data.
Every request (merchant app or storefront widget) is scoped to a single tenant. Reviews, cached data, and media files are all isolated per merchant.
Widget Delivery & Storefront Performance
The WiserReview widget is designed to have zero impact on your storefront's performance and security. It loads asynchronously from the CDN, executes after your page has rendered, and never sends your site's cookies or credentials to WiserReview servers.
The WiserReview widget loads asynchronously after your page has fully rendered. It never blocks your storefront's content or performance.
Non-Blocking Load
Script uses the defer attribute and loads asynchronously from CDN. It does not block page render or DOMContentLoaded.
CDN-Delivered
Served from Cloudflare's 300+ edge locations worldwide. Sub-50ms latency to most regions with global caching.
No Credential Leakage
All API calls use credentials: 'omit', preventing any cookies or auth tokens from your domain being sent to WiserReview.
Isolated Execution
Widget uses namespaced variables to prevent conflicts with your site's JavaScript. No DOM interference.
Lightweight Payload
Only the required theme JavaScript is loaded per widget type. No heavy frameworks or bundled dependencies.
DDoS-Protected Delivery
Widget delivery inherits Cloudflare DDoS protection. CDN absorbs traffic spikes without impacting your origin.
Auto-Scaling & High Availability
Every layer of the platform scales independently. During traffic spikes, the system automatically provisions additional capacity without manual intervention. Your storefront is never affected by WiserReview scaling events.
Each layer scales independently. CDN absorbs widget traffic, compute scales horizontally, and database distributes reads across replicas.
