Case Study: NWS PX Server Decommissioning
|
|
|
|
| Customer: |
National Weather Service (NWS), National Oceanic and Atmospheric Administration (NOAA), U.S. Department of Commerce (DOC)
(Raytheon Company, prime contractor) |
 |
| Goal: |
Determine feasibility of decommissioning existing AWIPS PX servers
|
| Application: |
- Make a specific recommendation regarding the feasibility of retiring existing AWIPS PX servers
- Develop alternative architectural solutions for providing equivalent or improved processing capability at identical or reduced cost
|
| Challenges: |
- Specifically quantify the technical impact on existing (NWS) systems of various solution recommendations (hardware replacement, code migration and conversion, etc.)
- Conduct rapid feasibility study activities and performance benchmarking that deliver accurate results in a timely manner while meeting management and reporting requirements and project performance constraints
- Provide comprehensive supporting analysis for NWS, in order to balance decisions on present alternatives and costs, and to effectively integrate these decisions into NWS technical architecture planning efforts
|
| FTI's Approach: |
- Identify a target platform to support re-hosting of PX applications
- Analyze software to determine impact and level of effort required to modify code for re-hosting on the target platform
- Modify software and hardware, as required, for re-hosting on target platform
- Test the reconfigured system and develop detailed technical benchmarks to quantify specific performance and financial impacts of the new architecture
- Report results and make go/no-go recommendations
- Recommended that the existing PX server hardware could be retired with minimal impact to the NWS
|
| Products Used: |
Red Hat Enterprise Linux 4.x, perl, shell scripting, Postgres SQL, AWIPS meteorology applications, PerfView benchmarking tool, GFE Automator
|
| Benefits: |
- Demonstrated and quantitatively supported ability to migrate legacy software to new baseline architecture without any software re-work, eliminating need to fund software conversion efforts, and minimizing technology modernization risk.
- Reduced NWS software maintenance expense via retirement of existing packages.
|
| Delivery: |
On time, within budget. Raytheon Six Sigma, CMMI Level 5, ISO 20000 project, EVMS-compliant project. Data transfer mechanisms compliant NWS OCIO security guidelines
