The Challenge

In January, Pennsylvania was suffering from the fifth-highest COVID-19 death toll, and lagged behind almost every other state in vaccine distribution. This was, in large part, due to the lack of central vaccine registration site.

As one of Pennsylvania’s largest integrated healthcare payers and providers, UPMC felt a responsibility to contribute to a solution.

The Solution

Together, the CEI and client teams quickly began building a vaccine registration site that could handle the intensity and large-scale number of submissions anticipated given the pent-up demand.

Load Test

Load testing tools proved that the capacity of the existing form solution in its current state would not scale to meet the massive demand of vaccine seekers.


Azure Platform Integration

Load testing tools proved that the capacity of the existing form solution in its current state would not scale to meet the massive demand of vaccine seekers.


Collab­­oration

When the initial architecture had been built and tested, CEI reached out to Microsoft in collaboration with the clients Web and Security teams to review and validate the architecture, hinging the success of this project to cross-team, cross-function, and cross-organization effort.


The Stack

The CEI team utilized multiple technologies to ensure the system was adaptable, secure, and able to provide useful metrics and data.

CDN, Server Bus & Azure Functions

To allow the application to handle large bursts of submissions, while providing a responsive experience.


Application Gateway & Azure Table Storage

To ensure the system was protected, and data was secured.


Azure Application Insights & Web Applications

To provide a combined view of usage and performance of the system.

Results

498,600

Submissions


The solution went live on February 17, 2021 and has handled over 498,600 submissions (120 submissions per minute at peak) for vaccine registration to date, with no issues reported.

237,726

Doses


As of March 15, 2021, the client had administered 237,726 doses of the vaccine, including 5,000 in one single day at a mass vaccination clinic at PPG Paints Arena.

80,000

Weekly Vaccinations


The client anticipates being able to schedule up to 80,000 vaccinations per week, contributing greatly to Pennsylvania improving from a rank of 49th in percentage of population fully vaccinated to 30th as of April 7th, 2021. CEI is proud to have been a part of the team that made this happen.

Client Development Manager

Although work is still being done, it was and is an important project and the team did a fantastic job. Everyone part of that project should be very proud.
