Dear Giovanni,

Sorry for the late response, I just had the chance to go through your questions. I am hoping you heard back from the node team in the meanwhile. In case you didn't, below are some answers.

Btw, for future requests, we recommend you to contact the following support channels to get a more timely response:

• for fiware lab questions: fiware-lab-help@lists.fi-ware.org
• for general questions : fiware-general-help@lists.fi-ware.org
• for GE related questions: fiware-tech-help@lists.fi-ware.org

• if you have other inquiries or need help escalating an issue: fiware-fiadopt-coaching@lists.fi-ware.org (this is the support channel our team is monitoring)

Hope this helps. Kind regards,

ilknur

Subject: Problems and questions from the FI-Adopt FAIRVILLAGE sub-project

Hi,
after using our FI-Lab account a few days during this month, we have a miscellaneous list of problems and questions.
Could you please tell me which aren't of your competence, so that I can send them to the fiware-lab@lists.fi-ware.org mailing list? Thanks.

1. NEED FOR MORE DETAILED DOCUMENTATION
Coming from a relatively trivial use of individual VMs at AWS and DigitalOcean, we are still trying to understand how different are the VMs of FI-Lab and which opportunities the use of Blueprint templates e software Tiers can offer.
On the FI-Ware websites we found many slide-style presentations on the FI-Lab (how to do), but no systematic and detailed documentation of its features (what they precisely are); it doesn't exist or it is hidden somewhere?

ANSWER1: Maybe you already saw these, but here are some info on Fiware Lab that could help you:
Fiware academy courses on cloud hosting: https://edu.fiware.org/course/category.php?id=4
Main lab help page: http://help.lab.fiware.org/
Architecture of cloud hosting chapter: http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/Cloud_Hosting_Architecture
infographic on Fiware Lab: http://infographic.lab.fiware.org/
quick starting guide: https://www.fiware.org/devguides/hosting-your-application-on-a-fiware-cloud/
Webinar on fiware lab: http://stream.global.dit.upm.es/videos/fi-ware/Webinar_31_3_2014-02.mp4

2. LEARNING HANDS-ON
We are trying to learn hands-on, by creating and destroying VMs, Blueprints and Tiers.
Is this OK? You confirm that the only constraints are those concerning the amount of resources (# of cores, memory and disk size, 1 floating
IP) ? ?
ANSWER2: Yes, this is ok. Btw, there are also constraints with the number of VMs. You can see all constraints here: http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/FIWARE_Lab:_Upgrade_to_Community_Account#What_are_the_default_quotas.3F

3. OBJECT MEMORY
We know that the Object Memory GE isn't available yet at the Trento node; for which date it is planned?
ANSWER3: Trento node team can answer this better, but I will also inquire.

4. NO FI-WARE GEs IN THE SOFTWARE CATALOG I've read on a forum post that some GEs cannot be added to a Tier in a Blueprint template, but only to a plain VM; do you confirm?
However, if I currently edit the "Software in instance" (Installed software), in the software catalog I find only 9 common OS packages (python, php, node, git ..), no FI-Ware GEs.
What is the difference between getting software from the FI-Lab software catalog and getting it from GitHub or installing it with apt-get, python pip, aso ?
ANSWER4: In theory, all GEs should be available in all forms over the FIWARE Lab. But this is not yet the case for all GEs. You need to check the info in the "instances" & "creating instances" tabs in the pages for the GEs you are interested in , in the FIWARE catalogue:
http://catalogue.fiware.org/enablers
The difference is, on fiware lab, you have the options of :
1-using the global instances of GEs
2-creating dedicated instances of GEs through VM images or blueprint templates
3-creating VMs from scratch with the OS, etc flabors you like plus adding GEs on top easily
If you just download the GEs from github, you need to build, deploy etc. everything from scratch without the help of VMs, templates, etc..
Btw, soon enough we will also add support for "Docker", i.e. for deploying GEs easily in Fiware Lab, or on your own machines. This is something currently being worked on by the FIWARE team.

5. UPDATING AND DELETING TIERS
After getting an error in trying to launch a Blueprint template, I realized that I hadn't set the minimum and maximum number of instances of Tiers.
But I get an error if I try to change the number of instances of a Tier when updating it; I can set them only when creating a new Tier.
Error updating tier ResourceMapPoi. Cause: 403 Error

However, I get an error even if I try to delete a Tier to create it anew.
Error deleting Tier.. Cause: 403 Error

ANSWER5: This question is better asked to the Fiware Lab help team. I will create a ticket, but next time you can send these type of questions directly to fiware-lab-help@lists.fi-ware.org to get faster response.

6. UNINSTALLING SOFTWARE IN INSTANCE
I added Python 2.7.5 to "Software in instance" to an instace based on base_ubuntu_14.04; while it was installing, I realized that release
2.7.6 was already present.
Now in the left pane (installed software) I read "Python 2.7.5 UNINSTALLED", and cant drag it to completely remove it. Is this OK?
ANSWER6. Again, this is best asked to fiware-lab-help. Iw ill add it to the ticket.

Thank you very much in advance!
Best regards, Giovanni

PS - at this moment our VM is not reachable from the Internet (193.205.211.174); yesterday or Saturday it was OK.
ANSWER7: do you still have this issue? If you do, please send a request to fiware-lab-help@lists.fi-ware.org to get support.
