Hi,

Please answer yes to the question below. This is the key of the server 
side not the one belongs to you.

>>> My answers to your questions:

>>> region you use? We can move forward only after that.
>>> 2. The images used in FIWARE can be accessed via ssh with your

>>> access within the vm, so you can configure username, password 
>>> authentication as well.
>>> 3. I assume that in the base images it is not the case. They only 
>>> provide a base system where you can freely decide what to install. 
>>> However, to deploy the necessary software stack the blueprint 
>>> templates can be used. To do so, first  you have to create a 
>>> blueprint template by choosing the region, base os, and the 
>>> softwares to be installed. After that you can deploy it, resulting 
>>> in a new instance with all the required softwares. Note that this 
>>> instantiation generally takes much more time than a simple image 
>>> deployment.
>>> 4. See 3.
>>> 5. If apache, php and mysql are also installed, I expect that the 
>>> answer is yes. If not, you can install it manually within the vm, 
>>> using aptitude or apt-get in ubuntu.
>>> 6. Free space is assigned to each vm, but it is not shown in the 
>>> portal. However, if the space is not enough, you can create 
>>> additional volumes in the portal, an assign them to the vm instance. 
>>> After that a new disk appears in the vm (e.g. /dev/vdb), that can be 
>>> formatted and then mounted similarly to a real physical disk.
>>>
>>> I also advise you to check the videos on instances and blueprints at
