Private or Public ?

Public clouds have some serious issues...

Data costs you money evenif you do not use them

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

The majority of cloud providers are companies subject to the USA Patriot Act law

Cloud providers mainly rely on proprietary or non standardized solution. This is a major

concern for development portability

...so we go private !

(Ideal) use case

A cloud infrastructure to store raw data imagery, process to orthorectified level and provide access to full resolution products

Real use case

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

OpenStack is a promising solution supported by several major IT actors

The deployment of and existing processing chain is straightforward

Accessing Cloud Storage from computing instances remains an issue since http paradigm

is incompatible with "filesystem like" tasks
