  2. Interfacing NOAA Systems 

  3. Interfacing NOAA systems II

  4. CIF System Overview • Three geographically separated similar systems designed to serve data to the public using Internet protocols • Goal: Provide NWS with an operationally supportable Internet presence • Designed for 99.9% availability • Deliver raw data, data services, graphics, text, etc, to all levels and types of customers • LAMP: Linux/Apache/Mysql/PHP

  5. System Overview • Farms have natively supported up to 1.1 Gb/s of traffic (~8k requests per second), most of which is dynamic (meaning requiring database queries, reading of large netCDF/GRIB2 cubes or both) • Selected data sets can be pushed out to contracted commercial vendors to leverage a 4 to 10 times increase in capacity (depending on data type)

  6. Architecture • Each farm is has 14 front end web servers, two web object caches to serve public requests • Each farm has a five node Mysql cluster • Each farm has about 20 systems dedicated on the back end to processing, parsing, etc, raw NWS data • Each farm has two NFS file servers, about 4 Tb total • XMPP Cluster (2/3 servers) (one farm per year)

  7. System Architecture

  8. Major System Interfaces • Public Internet (SSMC (2Gb/s)/SRH(1Gb/s)/CRH(140Mb/s) • SSMC Open Campus, TOC, Regional networks • NOAAnet, SBN, Sockets • LDM, rsync, ftp, scp, browser upload via Content Management System

  9. Standards and Formats • Load balancing: DNS • Incoming data streams: NetCDF, GRIB2, GRIB2/Cube, WMO, xml, various graphics, radar binary • Outgoing: HTML, CSS, RESTful, SOAP, XML/XSL, RSS/ATOM, CAP, DWML, OGC, Shp, WFS, zip, XMPP, various graphics • Up and coming: WMS, XMPP, DM-open • Open Layers mapping displays • Inside: NFS, GFS, SVN, SQL

  10. Dev Schedule and Milestones • CAWS: Oct • AHPS Phase VI: Nov • 3rd Generation Marine Wx Portal: Winter • High speed file servers: Oct/Nov • Major network realignment: December • 1st consolidated C&A: December/Jan • CAP XMPP/DM-open push test: Winter/Spring? • RIDGE 2: Spring ’10 • NextGen Watch/warning maps: Spring ’10? • Completion of WFO migration to CMS: Summer ’10

  11. Governance Structure • 60-1 series of NWSI • Internet Configuration Control Board • Supported by Web Tactical Team for usability/science decisions • Online ticketing system used to track trouble tickets, feature requests, configuration changes • Docu-wiki used to develop/maintain documentation
