- After the last meeting, Michaël Dupont provided a version of ATLASViewer
which can be run against arbitrary image servers.  MV reported that he
had deployed ATLASViewer on two VMs on the EGI fedcloud; one pointing to
the image server with data at dCache/DESY and the other pointing to the
image server with data at OneData/Cyfronet.  The addresses are:

http://155.210.198.204/ (OneData) 
http://155.210.198.214/ (dCache)

Michaël Dupont later confirmed that the performance was similar to the
viewer running on HBP infrastructure.  

- LZ reported that the Cyfronet team had tested with multiple image
server Dockers load balanced with NGINX, with 10 image server instances
appearing to be optimal.  The resulting performance boost meant that
approx. 10 concurrent users can now achieve the target of <1s for serving
8 tiles.  There does appear to be more room for NGINX optimization and the
Cyfronet team will continue experimenting.

It was agreed that the dCache team should also look at load balancing to
achieve a similar performance boost, either based on Cyfronet's NGINX
configuration or a new configuration from scratch.  

-> MV to talk to Christian Bernhardt about deploying load balancing

- CZ had told MV that the her team now have access to a larger image stack
in raw format and they are working to process the data to transform the
stack in the format read by the image service.  This will help with
scalability testing of the pilot.

- OA said that progress was being made on OpenID Connect to secure access
to the datasets and integrate the pilot with HBP accounts, but that a
fully working solution probably won't be ready by the end of January.
However, OA can provide a test client to enable us to do some preliminary
integration with the pilot.

-> MV to add OA to the mailing list and provide contact details
-> OA to send LD,MV a test client to demonstrate interoperability with HBP
instance of OpenID Connect

- MV and Tiziana Ferrari are arranging a meeting with Sean Hill to discuss
and agree upon the concrete outputs of the pilot that are should be
delivered by the next funding period of HBP (from Apr '16) in addition to
more details required to write a cost model for deploying and running HBP
services on EGI infrastructure.
