Current environment

Windows Server 2016 virtual machine

This virtual machine (VM) runs BizTalk Server 2016. The VM runs the following workflows:

- Ocean Transport C This workflow gathers and validates container information including container contents and arrival notices at various shipping ports.

- Inland Transport C This workflow gathers and validates trucking information including fuel usage, number of stops, and routes.



The VM supports the following REST API calls:

- Container API C This API provides container information including weight, contents, and other attributes.

- Location API C This API provides location information regarding shipping ports of call and trucking stops.

- Shipping REST API C This API provides shipping information for use and display on the shipping website.



Shipping Data

The application uses MongoDB JSON document storage database for all container and transport information.



Shipping Web Site

The site displays shipping container tracking information and container contents. The site is located at http://shipping.wideworldimporters.com/



Proposed solution

The on-premises shipping application must be moved to Azure. The VM has been migrated to a new Standard_D16s_v3 Azure VM by using Azure Site Recovery and must remain running in Azure to complete the BizTalk component migrations. You create a Standard_D16s_v3 Azure VM to host BizTalk Server.

The Azure architecture diagram for the proposed solution is shown below:







Requirements

Shipping Logic app

The Shipping Logic app must meet the following requirements:

- Support the ocean transport and inland transport workflows by using a Logic App.

- Support industry-standard protocol X12 message format for various messages including vessel content details and arrival notices.

- Secure resources to the corporate VNet and use dedicated storage resources with a fixed costing model.

- Maintain on-premises connectivity to support legacy applications and final BizTalk migrations.



Shipping Function app

Implement secure function endpoints by using app-level security and include Azure Active Directory (Azure AD).



REST APIs

The REST API’s that support the solution must meet the following requirements:

- Secure resources to the corporate VNet.

- Allow deployment to a testing location within Azure while not incurring additional costs.

- Automatically scale to double capacity during peak shipping times while not causing application downtime.

- Minimize costs when selecting an Azure payment model.



Shipping data

Data migration from on-premises to Azure must minimize costs and downtime.



Shipping website

Use Azure Content Delivery Network (CDN) and ensure maximum performance for dynamic content while minimizing latency and costs.



Issues

Windows Server 2016 VM

The VM shows high network latency, jitter, and high CPU utilization. The VM is critical and has not been backed up in the past. The VM must enable a quick restore from a 7-day snapshot to include in-place restore of disks in case of failure.



Shipping website and REST APIs

The following error message displays while you are testing the website:

Failed to load http://test-shippingapi.wideworldimporters.com/: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://test.wideworldimporters.com/' is therefore not allowed access.

Background

You are a developer for Proseware, Inc. You are developing an application that applies a set of governance policies for Proseware’s internal services, external services, and applications. The application will also provide a shared library for common functionality.



Requirements

Policy service

You develop and deploy a stateful ASP.NET Core 2.1 web application named Policy service to an Azure App Service Web App. The application reacts to events from Azure Event Grid and performs policy actions based on those events.

The application must include the Event Grid Event ID field in all Application Insights telemetry.

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.



PolicyLib

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.
