Elephants and Armed Forces

FOSS and Brazil • Wide use in companies and government – Strong support in the current federal administration – Communities – Anti-piracy policies • FOSS is now a state policy – Federal law enforces its use in government organizations • Many successuful cases in the last 10 years

Brazilian Army and FOSS The adoption of FOSS is considered definitive for the Brazilian Army. Reasons for FOSS adoption • Cost savings in medium and long term • Better security, stability and availability offered by FOSS • Reduction of mandatory changes that closed models periodically require • Technical independence • Development of local expertise • System accountability • Independence from a single supplier * Army Migration Guide to FOSS, www.softwarelivre.gov.br/casos/Plano_Migracao_Soft_Livre_13FEV07.pdf

Brazilian Army DEC - Department of Engineering and Construction is responsible for: • guidelines • planning • coordination, and • control of construction activities and Army properties

Brazilian Army Division of Military Building Works Organization responsible for the activities of construction, expansion, reform, adjustment, repair, restoration, preservation, demolition and removal of military installations.

Opus Project Motivation • 642 Army Units have 12ª RM 8ª RM 10ª RM properties 7ª RM • Total of 1.817 properties 11ª RM 6ª RM 9ª RM • 60.000 property improvements 4ª RM 2ª RM 1ª RM • Demand for 5.000 building works/year 5ª RM • Current capacity: 2.000 3ª RM building works/year

Opus Project Main objectives – OPUS system aims to support the functionalities of planning, control, management and execution of all activities of military building works – Accessed by all units of the Brazilian Army – Integrated Geographic Information System • Google Earth integration – Simplicity to use and access information – 5.000 concurrent users • Prepared for 50.000 concurrent users

Opus Project Technologies – Java Enterprise Edition 5 – PostgreSQL + PostGIS – Linux CentOS 5.2 – Jboss AS – GIS • MapServer • GeoServer • OpenLayers • GeoTools • EJB3Spatial

Production infrastructure Four Linux CentOS servers - A cluster of two JBoss servers - Two PostgreSQL servers (warm-standby)

FAB - Brazilian Air Force • SDAB is the department responsible for Logistics Support • SDAB was pioneer to use PostgreSQL and started using in FORÇA AÉREA BRASILEIRA 2005 – Systems • Sisub, Food Supply • Sifare, Military garment ecommerce • SIA, Procurement DIRETORIA DE INTENDENCIA SUBDIRETORIA DE ABASTECIMENTO

FAB – SISUB Project • System for supply acquision and management of FAB's eateries • Features – Support to procurement – Warehouse and stock control – To standardize menus – Control number and cost of meals per eatery – Generate performance indicators

Brazilian Air Force Situation before Sisub system – Each quarter had to send monthly a pile of forms – A soldier had to retype all those forms in a spreadsheet – Unecessary overhead – Information gap of one to two months – Mistakes and lost of information – Waste of time, money and trees

FAB – Sisub Project Technologies – EJB 3 – PostgreSQL – Tapestry framework – Slony – JPA (Java Persistence API) – Debian Linux – Jasper Reports – JBoss – Python

FAB Projects • System architecture – 54 database servers distributed in 19 states – Two-way replication system – Central replication server for fallback – A datamart for key performance indicators – The main database size is 200 Gb

Results • System Benefits – Nutritional control of all meals – Transparency in management – Waste reduction – Agility and less bureaucracy – Online process management – Automated performance indicators

Results • Some numbers: – ~100.000 meals daily – 1.000 concurrent users (and counting) • Cost reduction – Improvement in process efficiency brings savings of US$ 3 million / year – Elimination of US$ 1 million in software license costs

Results

Conclusion about PG and FOSS • Reliable • Adaptable • Scalable • Low costs
