Implementing fault tolerance to mission critical infrastructure for Medical Plan


A leader is medicare services lacked redundancy in what it termed mission-critical systems. EQUOLOGIX has partnered with this client since 2011 to not only deliver in these services, but also provide ongoing support.

Industry Landscape

An organization’s infrastructure is the lifeline of any business.  Any and all facets of the business is impacted by any and all outages sustained.  Because medical plans are heavily regulated, reliability and accessibility is pivotal. Medical Plans are heavily regulated by the government. As such, the are compliance and regulatory standards for which need to be adhered to.  For instance, departments such as medical management, claims, Part-D, Part-C, Member Services cannot afford any downtime on systems like email, faxing, phones [IVR] and Provider Web Services. Downtime means penalties assessed to the plan.


In order to address and mitigate these factors, the client was looking implement redundant systems.  Any and all systems which lacked redundancy was termed “in-scope”. Phones, Database Systems, Application Systems, Network Infrastructure, Messaging Systems, etc.

Historically, the client’s staff have suffered as a result to unforeseen outages.  The organization as a while has also suffered and sustained loss of revenue and penalties.  To help us deliver on this requirement, the customer asked that we produce a Business Case, a Technical Design Document and Project Plan which would encompass the overall solution. The client asked that mission-critical systems be made redundant, and that each system be tested to certify reliability.

As part of the overall solution, the customer also requested, thorough documentation, testing of fail-over and knowledge transfer.


Our team performed an initial assessment to define the in-scope systems, once the discovery process  was completed, based on customer data, scope of work, and deliverables, our Subject Matter experts produce the design for the solution.  The solution was then shared with our customer. Once approved, we moved onto the POC Phase. A Proof of Concept environment was deployed for all systems in-scope and a subset of employees selected as test subjects.   After our testing phase, and certifying the solutions, we moved to the implementation phase.

The entire project was documented, from start-to-finish. This documentation was provided to our customers at the completion of the project. This phase is all about reliability and scalability.   We delivered on the framework and certified it.


Once project was was completed, systems, e.g. firewalls, Enterprise Anti-Virus, Database Systems, IVR systems, Citrix Servers, Domain Controllers, File and Printer Server, Application Servers, Exchange Messaging Systems, were fully redundant and scalable as needed.

Key Success Factors


This engagement was successful due to the very high level of communication and collaboration between EQUOLOGIX’ development team and client stakeholders. Our methodology allowed us to seek continual feedback on the course components as they were being developed, helping to ensure the program achieved the client’s goals and desired program aesthetic. Additionally, during the initial scoping process, we were able to present a very clear vision of our approach that aligned to the client’s expectations. The development team was then able to execute upon that approach by successfully working with client SMEs to develop a realistic and engaging redundant infrastructure.
