Policy service must use Application Insights to automatically scale with the number of policy actions that it is performing.



Policies

Log policy

All Azure App Service Web Apps must write logs to Azure Blob storage. All log files should be saved to a container named logdrop. Logs must remain in the container for 15 days.



Authentication events

Authentication events are used to monitor users signing in and signing out. All authentication events must be processed by Policy service. Sign outs must be processed as quickly as possible.

You have a shared library named PolicyLib that contains functionality common to all ASP.NET Core web services and applications.

The PolicyLib library must:

✑ Exclude non-user actions from Application Insights telemetry.

✑ Provide methods that allow a web service to scale itself.

✑ Ensure that scaling actions do not disrupt application usage.



Other

Anomaly detection service

You have an anomaly detection service that analyzes log information for anomalies. It is implemented as an Azure Machine Learning model. The model is deployed as a web service. If an anomaly is detected, an Azure Function that emails administrators is called by using an HTTP WebHook.



Health monitoring

All web applications and services have health monitoring at the /health service endpoint.



Issues

Policy loss

When you deploy Policy service, policies may not be applied if they were in the process of being applied during the deployment.



Performance issue

When under heavy load, the anomaly detection service undergoes slowdowns and rejects connections.



Notification latency

Users report that anomaly detection emails can sometimes arrive several minutes after an anomaly is detected.

Background

Overview

You are a developer for Contoso, Ltd. The company has a social networking website that is developed as a Single Page Application (SPA). The main web application for the social networking website loads user uploaded content from blob storage.

You are developing a solution to monitor uploaded data for inappropriate content.



The following process occurs when users upload content by using the SPA:

• Messages are sent to ContentUploadService.

• Content is processed by ContentAnalysisService.

• After processing is complete, the content is posted to the social network or a rejection message is posted in its place.



The ContentAnalysisService is deployed with Azure Container Instances from a private Azure Container Registry named contosoimages.

The solution will use eight CPU cores.



Azure Active Directory

Contoso, Ltd. uses Azure Active Directory (Azure AD) for both internal and guest accounts.



Requirements

ContentAnalysisService

The company’s data science group built ContentAnalysisService which accepts user generated content as a string and returns a probable value for inappropriate content. Any values over a specific threshold must be reviewed by an employee of Contoso, Ltd.

You must create an Azure Function named CheckUserContent to perform the content checks.



Costs

You must minimize costs for all Azure services.



Manual review

To review content, the user must authenticate to the website portion of the ContentAnalysisService using their Azure AD credentials. The website is built using React and all pages and API endpoints require authentication. In order to review content a user must be part of a ContentReviewer role. All completed reviews must include the reviewer’s email address for auditing purposes.



High availability

All services must run in multiple regions. The failure of any service in a region must not impact overall application availability.



Monitoring

An alert must be raised if the ContentUploadService uses more than 80 percent of available CPU cores.



Security

You have the following security requirements:

- Any web service accessible over the Internet must be protected from cross site scripting attacks.

- All websites and services must use SSL from a valid root certificate authority.

- Azure Storage access keys must only be stored in memory and must be available only to the service.

- All Internal services must only be accessible from internal Virtual Networks (VNets).

- All parts of the system must support inbound and outbound traffic restrictions.

- All service calls must be authenticated by using Azure AD.



User agreements

When a user submits content, they must agree to a user agreement. The agreement allows employees of Contoso, Ltd. to review content, store cookies on user devices, and track user’s IP addresses.

Information regarding agreements is used by multiple divisions within Contoso, Ltd.

User responses must not be lost and must be available to all parties regardless of individual service uptime. The volume of agreements is expected to be in the millions per hour.



Validation testing

When a new version of the ContentAnalysisService is available the previous seven days of content must be processed with the new version to verify that the new version does not significantly deviate from the old version.



Issues

Users of the ContentUploadService report that they occasionally see HTTP 502 responses on specific pages.
