Topic 2, Contoso Pharmaceutical
Background
Contoso Pharmaceuticals has an on premises solution for patients in hospice care. The solution consists of a Xamarin mobile application and a Microsoft SQL Server database. Health care providers use the solution to monitor and manage patient drug dosage and treatments. The solution uses third-party software to calculate drug prices and dosages. The third-party software has several different modules that run on various server systems.
Contoso Pharmaceuticals would like to migrate the solution to the cloud and leverage several features of Azure. The company would like to use Platform as a Service (PaaS) where possible.
You are evaluating the use of Azure Service Fabric as well as Azure App Service API Apps to host several of the software's functionality as REST API services.
You develop a drug pricing endpoint as an Azure App Service API app. The drug pricing endpoint requires API discovery that uses the Swagger RESTful API Documentation Specification (also known as the OpenAPI specification). Developers would like to generate Operation identifiers for overloads of their controller methods. In addition, developers are finding it difficult to secure the API endpoints by using authentication and authorization to restrict access to certain resources within the app without writing extra, custom code.
You develop a drug dosage endpoint as a Service Fabric. OWIN hosted. HTTPS endpoint Developers are having difficulty writing and maintaining code to wrap client-side communication libraries in a retry loop for situations when the endpoints are down.
DevOps have extensive experience with PowerShell and would like to maintain Azure resources by using Azure PowerShell.
Business Requirements
Patients
Patient data must be stored securely. Data security must meet the Health Insurance Portability and Accountable Act of 1996 (HIPPA) standards in the United States and must meet the ISO/ICE 27002 data security standards in the rest of the world.
Drug Pricing and Dosage Software
The third party software was a very large investment for the company and contains several different modules that run on various server systems. The solution must be moved to Azure as the on-premises data center is costing the company too much in hardware renewal fees, not being properly backed up for a disaster recovery situation, and not being securely maintained to organizational security and compliance requirements.
Drug Pricing and Dosage Software Platform-as-a-Service (PaaS)
The company is looking to migrate to a PaaS solution to include implementation of the various software feature. The business would like to see a reduction in costs while increasing scalability, reliability, and resiliency. The company would like to ensure a seamless transition to the new solution while maintaining all features of the current drug pricing and dosage software.
Mobile
Several health care providers have connectivity issues with their mobile devices. The patient information and drug dosage is vital information that must be captured at each patient visit. The business would like the information to be delivered to a central location to be securely stored and used for reporting purposes.
Technical Requirements:
The software requires several virtual machines (VMs) due to the software's use of the operating system and code operation. The software cannot run on an Azure PaaS service due to this restriction. The organization require, the VMs to be secured while active and .it rest using industry standard encryption technology to address organizational security arid compliance requirements. You plan to use Azure Key Vault to control the VM boot using keys and policies to comply with audit requirements. All VMs will be created by using the Azure Resource Manager The software consists of several VMs that run drift-ting operating systems and handle differing workloads. The VMs are defined as follows:
- DrugPricingVM - The Linux VM runs Ubuntu Server and requires a Server Message Block (SMB) interface to access files from the VM. The VM must allow the use of file system APIs. The VM mint also access on premises resource's while hosted in Azure.
- DrugDosageVM - The Linux VM runs Ubuntu Server and uses REST APIs to store very large amounts of unstructured data for random access and streaming used to process drug dosages.
- DrugProcessingVM - The Windows VM runs Windows Server and includes a Windows Communication foundation (WCF) service to process drug pricing and dosage requests. The VM requires a storage solution that guarantees first-in-first-out (FIFO) ordered delivery to ensure processing order of the requests is maintained.
Standard processing requests are less than 256 kilobyte (KB) and include automatic duplicate detection.
- DrugDataVM - The Windows VM runs Windows Server and SQL Server to store the patient treatments dosage information, as well as finalized costing information for the treatments.
All VMs must be deployed using automated, repeatable processes that can be audited and validated. All VMs should be initially created, configured and deployed as one logical unit within a single resource group. In addition, all VMs should include monitoring and diagnostics to be enabled by using the Azure Diagnostics extension. All diagnostics and monitoring of VMs should be captured and stored by using a storage account.
Architecture in evaluating the use of Azure service Fabric as well as Azure App Service API Apps to host several of the software's functionality as REST API services.
A drug pricing endpoint has been developed and implemented as an Azure App Service API app. The drug pricing endpoint requires AW discovery using the Swagger RESTful API Documentation Specification (also known as the OpenAPI specification). Developers would like to generate operation identifiers for overloads of their controller methods. In addition, developers are finding it difficult to secure the AW endpoints by using authentication and authorization to restrict access to certain resources, within the app without writing custom code. The API endpoint should be secured to only allow communication between each of the endpoints and disallow access from external communications.
A drug dosage endpoint has been developed and implemented as a Service Fabric, OWIN hosted, HTTPS endpoint. Developers are having difficulty willing and maintaining code to wrap client-side communication libraries in a retry loop for situations when the endpoints are down.
Network Communications
All VMs require inbound traffic communications on port 50001 for both UDP and TCP communications. All VMs must be configured to run within the same subnet.
Mobile
The connectivity for mobile devices must support offline mode to allow users to continue modifying and create data when the device is offline. When the app is back online, it must synchronize local changes with a central repository stored in Azure.
The mobile must cache server data locally on each device. The solution must synchronize data across multiple devices while detecting conflicts when the same record is modified by two or more devices. The synchronization must be incremental to reduce network traffic.
Development
Developers must use Microsoft Visual Studio on their desktops and store all code in a source repository hosted by using Visual Studio Team Services.
