[Fiware-lab-help] FI-LAB VMs (smartCarpool project - frontierCities grantee)

[Liana Napalkova]

Dear Mr./Mrs.,

In my previous email I requested the JIRA account, however it looks like 
it is only allocated for GE owners and FIWARE LAB Node owners.

That's why below I directly specify the technical requirements that we 
would need for our project, along with justifications.

Please let me know if any further details are needed.

*VM1: calculation server**
*• 16GB RAM
• 20GB of a hard disk space
• 1 public IP
• 8 VCPUs

This virtual machine requires 16GB RAM and 8 VCPUs to avoid slowness 
between concurrent and heavy calculations that we will execute in our 
Carpooling Search and Analytics Engine. Moreover, 16GB RAM is required 
to load the cartography in the memory at some moment.

*VM2: web server**
*• 16GB RAM
• 20GB of a hard disk space
• 2 public IP
• 8 VCPUs

As any WEB sever of a medium demand, we would need a considerable amount 
of CPUs in order to execute all the petitions. If we have 8 VCPUs, there 
might be some bottlenecks in some particular cases, however, in general, 
it should be sufficient. The motivation for RAM is similar to the 
calculation server. Finally, we need 2 public IPs in order to avoid 
frequent bottlenecks provoked by concurrent petitions and network velocity.

*VM3: database server**
*• 4GB RAM
• 0GB of a hard disk space (*80GB volume will be attached to the instance*)
• 1 public IP
• 2 VCPUs

We need 80GB of a hard disk space in order to store (i) all the 
cartography, (ii) user-specific data and (iii) Analytics Engine outputs.

Thanks.

Best wishes,
