5. Private or Public ?
6. Public clouds have some serious issues...
7. Data costs you money even if you do not use them
8. process 1 € store 5 € access 0.5 € to + 1 time per year each time (Very) approximative computations for a 20x20 km PA+XS Pleiades product - based on Amazon EC2 and S3 pricings
9. The majority of cloud providers are companies subject to the USA Patriot Act law
10. Cloud providers mainly rely on proprietary or non standardized solution. This is a major concern for development portability
11. ...so we go private !
12. (Ideal) use case
13. A cloud infrastructure to store raw data imagery, process to orthorectified level and provide access to full resolution products
14. Real use case
15. OpenStack on a small cloud (20 processors) storing SRTM tiles - Two steps processing chain, using OTB and including hill shading followed by spherical mercator reprojection ("Google") - Results tiled and accessed through WMS protocol * ORFEO Tool Box - http://orfeo-toolbox.org *
16. Video
17. OpenStack is a promising solution supported by several major IT actors
18. The deployment of and existing processing chain is straightforward
19. Accessing Cloud Storage from computing instances remains an issue since http paradigm is incompatible with "filesystem like" tasks
