How we built our cloud based physician portal web, mobile and HL7 Interface engine – 01

AZ-Tech Radiology is one of the leading medical imaging organization that provides the highest quality imaging services utilizing state-of-the-art equipment and technologies in Arizona.  Our primary goal is “Keeping the referring physician happy”, all roads lead to the ease of delivery of “radiology reports” to them and their sending of orders to the lab”

In order to meet the goal, we have to have state of the art technological solution which drove us to build the new cloud based connected IT systems:

  1. Radiology Information System
  2. HL7 Interface Engine which connects all of our modalities, external EMR and Insurance companies, pushing data to the cloud in a secure manner.
  3. Promotional Website @ https://www.aztechradiology.com
  4. Physician Portal to delivering the reports @ https://provider.aztechradiology.com/
  5. Physician mobile app @ https://m.provider.aztechradiology.com/

In this blog post I would like to share the Architecture we came up with which powers our IT systems.

End result

After we implemented the solutions in phased manner starting from Jan 2018 uptil now, following are the benefits we gained

  1. Average speed of our report delivery time reduced from days to minutes
  2. Cost of the delivery of reports reduced multi-fold otherwise we enagened half a dozen employees faxing the reports to the physician office manually
  3. We can deliver the reports to physican hands thru our mobile solution
  4. We automated the sending of Fax (reports) to the clinics who still needs paper copy of the reports
  5. Customer satisfaction thru enhanced user experience in the form of simple to use web and mobile application
  6. Powers 1000’s of reports per day with ability to auto-scale to handle more reports in the future

Elegant & Re-usable diagrams for Architecture, System Design, Pre-Sales & Proposal activities etc.

If you are a Solution Architect or Presales team members then I am sure you would have prepared numerous diagrams for proposals, system design, Business Process flows etc. using varieties of tools i.e. MS Visio, Excel, Word and online tools like draw.io, lucid chart and many more…

I use all of these above tools but most predominantly Excel for stunning diagrams. Some of my diagrams I made it as excel template for re-usability which you can get it here and modify as per your need.

Sample Diagrams of mine…. [ Inspirations of the diagrams are from internet, reference books and some are my own ideas but I usually create it as fresh] . Download the excel template here.

Free hosting for 3 years in MS Azure IaaS Platform

Microsoft provides $150 per month worth of hardware for free of cost for 3 years in their cloud infrastructure “Azure” and the program is called “Bizpark” [http://www.microsoft.com/bizspark/azure/]. This is applicable for start-up companies which are less than 5 years old and their annual revenue is less than 1 Million USD.

We recommend “Bizpark “ to our SME prospects and clients (Start-ups) to get benefit from the free Scheme. 

Our default deployment architecture we propose in our proposals for start-ups or individuals who would want to built web (REST APIs) application in Microsoft footprint (ASP.NET MVC) to start as small and scale up is depicted below.

DEPLOYMENT ARCHITECTURE

The server infrastructure (hardware & software) will be procured from Microsoft Azure, Infrastructure as service (IaaS). The high level deployment architecture of Microsoft Azure infra is depicted in below

clip_image002

The advantages of Microsoft Azure, IaaS are: (Everyone knows but nevertheless)

  • No upfront Server hardware investment
  • On demand  Server & Storage scale-up or scale-down
  • Load balanced using Traffic Manager (Optional)
  • High availability using Traffic Manager & Geo- redundant (Optional)

HARDWARE DETAILS

No sophisticated hardware is required. The application will be hosted in MS Azure Cloud and on demand the hardware can be scaled up without altering the source code (mainly for fault tolerance and load balancing). Typically we need the following three components

  • Azure Web Site
  • Azure SQL Server Database
  • Azure Cloud Storage

Note: Azure is not only for windows. Azure supports a broad set of operating systems, languages and frameworks— From Windows to Linux, SQL Server to Oracle, .Net to Java, PHP, Python, Ruby, Node.js, Hadoop.
