MHS Genesis System Solution Architecture

Vista Defense is assisting Defense Health Agency (DHA) in the implementation of a new infrastructure and application service framework for use in all medical treatment facilities (MTFs) in the Tri-Services. The goal is to produce an enterprise-managed delivery of Information Technology from the Data Center to Desktop (D2D) program that provides a predictable and acceptable end-user experience in support of MHS Genesis. The end product will deliver core infrastructure, tools, and processes to centrally manage and continually monitor devices used to support the core medical communities of interest (Med-COI). Infrastructure architect functions include:

 

• Active Directory/Identity, Authentication, and Authorization Management (IdAM)
• Infrastructure Storage Solutions Architecture
• IT Services Management Architecture (Service Design)
• Enterprise Management of End User Devices (EUDs) and Application Delivery
• Enterprise Mobile Solutions (cloud platform)
• Security Solutions Architecture
• Server and Desktop Virtualization
• Network, Engineering, and Security Architecture
• Application Architecture (Citrix/AppSense)

Windows 10 Migration and Compliance Support

For DHA, Vista Defense is implementing a cutting edge software solution that allows for an unprecedented mass migration against a very aggressive time-line within an inconsistent environment. Vista Defense is migrating DHA to a Windows 10 environment. We are providing DHA with an enterprise migration solution method that gives a consistent software approach across all service environments. This is a result of the current legacy Army Microsoft System Center Configuration Manager (SCCM) infrastructure not being able to support management of Windows 10 and the Navy has limited SCCM expertise. This software solution for migration of computer assets to a Windows 10 posture allows DHA to utilize the expanded capabilities and advanced security features of Windows 10.

We provide planning, and technical coordination support prior to, during, and after the successful achievement of Authority to Operate (ATO) for the Solution Delivery Division. Vista Defense also supports all related system lifecycle cybersecurity documentation required as a result of significant architecture and design changes (e.g. Risk Assessments, Annual and Technical Reviews, Agile and Waterfall development cycles). Support functions include:

 

• Assessment and Authorization (A&A) Execution
• Cybersecurity Engineering Support
• Vulnerability Management

 

DHA Data Science and Decision Analytics Support

Data scientists provide expertise in the areas of predictive analytics, business intelligence, data discovery, statistics, data science, and research for the Defense Health Agency. Data scientists support data and research requests and projects related to prevention, injuries, medical readiness, readmission, clinical preventive services, suicide, opioid misuse, and other health service-related issues. Data scientists are responsible for supporting both operational and research data and analytical needs for MHS. Core activities focus on enterprise measurement, development and support of clinical registries, and data request fulfillment. Data discovery and research activities focus on development of de-identified data sets and reports for health statistics, research consultation, and use of big data, machine learning, and predictive analytics techniques.
