Pleiades & Spot

Spot Image Ground Segment
implementation : Critical items
The compliance with SLA requirements (performance, availability) should be
a critical point.
Spot Image IT architecture and global software architecture : façade layers,
legacy database are imposed and mandate a two-step implementation plan
• First step: functional SPOT services implementation based on existing IT
infrastructure ;
calibration/evaluation/benchmarking of performances reached by infrastructure (global
infrastructure including ESA portal and DAIL layers)
set up diagnostics of benchmarking phase : identify bottlenecks, performances
problems, time consuming layers…propose update IT architecture
• Second step: Implement update IT architecture for SPOT services
commit on SLA requirements derived from
Anticipate Pleiades services implementation
