Customer Challenge

Pharos Innovations is a medical technology provider processing PHI data. As such, they fell under the jurisdiction of HIPAA regulations and were having trouble scaling their architecture with their on-premise data center.

“Jason and team took our small old school thinking web architecture and ‘AWS-‘ifed’ it.  Their support, leadership and expertise has given us the confidence we need to build a scalable infrastructure to meet our growing business needs.”

Ryan Royal, Vice President of IT

The Solution

After an extensive search and recommendation from Amazon, Six Nines was selected as the consulting and migration partner to architect and build Pharos Innovations cloud-based environment.

Six Nines started by conducting an architecture review and assessment of the current on-premise environment. After mapping Pharos’ on premise technical stack, Six Nines architected a proposed infrastructure on AWS and presented for review to Pharos.

The architecture that was proposed and built utilized AWS’ HIPAA compliant services and managed services. The design was a VPC with a web tier on a dedicated host in a public subnet behind a public-facing Elastic Load Balancer (ELB.) Traffic was then routed to an internal ELB into a .NET application server in a private subnet, also on a dedicated host. The application tier traffic was then routed into a second private subnet holding a Relational Database Service (RDS) MSSQL database.

The application tier and database tier were allowed external internet access for updates via the NAT server in the public subnet.

By leveraging the AWS environment, Pharos was able to scale immediately to meet growing, world-wide demand. It also paved the way for additional horizontal scalability by preemptively including external and internal ELB’s pointing towards the Web and App tiers respectively. The RDS MSSQL is easily scaled for both HA and DR when Pharos deems necessary.

Six Nines utilized the following AWS services in the final solution:

  • Amazon VPC – Virtual Private Cloud
  • ELB – Elastic Load Balancing
  • RDS – Relational Database Service MSSQL
  • Route 53 – DNS Service

Result and Next Steps

Six Nines finished the project on-time and under-budget delivering a scalable and highly-available infrastructure with no single point of failure. Pharos was happy with the deliverables and the executed timeframe. Should the need arise to extend or modify their infrastructure further, Six Nines is available to continue the relationship.
