Installation

Server

Exivity can be installed on any Microsoft Windows 2012 R2 or higher server in your on premise data center or in the cloud. Depending on the amount of data, Exivity recommends the following system configuration:

Deployment	Data sources	CUPR	CPU	Memory	Storage
Tiny	2	1 000	1 Core	4 GB	25 GB
Small	2	2 000	2 cores	8 GB	50 GB
Medium	4	5 000	4 cores	16 GB	100 GB
Large	8	15 000	8 cores	32 GB	200 GB

Both the Data sources and CUPR in above tables are recommended limits. All systems should have a standard C: OS drive. The storage recommendation in the table above is for a D: drive, which preferably is SSD.

Client

The Exivity front-end supports the following desktop browsers:

• Google Chrome v59+

• Microsoft Edge v41+ (EdgeHTML 16+ / Blink 80+)

• Opera v46+

• Mozilla Firefox v65+ (support added in Exivity v2.10.0)

• Apple Safari v10.1+ (support added in Exivity v3.2.7)

We aim to provide the fastest metering and billing solution available today, and this means we have to rely on modern (web) technologies. Part of our speed comes from pre-processing the raw data, and part comes from having almost all processed data available right in the browser, and streaming the missing pieces on request.

To efficiently and reliably achieve this we use some very specific technologies not yet available in all browsers. When they do catch up, we'll fully support those browsers.
