What are the typical hardware requirements for InSite?
Insite can run on dedicated hardware, or as a virtual appliance.
Hardware options:-
- Virtual: 4 vCPUs, 8GB RAM and 50GB disk as standard
- 4GB for a small to medium environment
- 16 vCPUs, 32GB RAM and 100GB disk for high numbers of sites
- Dedicated: Quad core, 8GB RAM 50GB disk
- 4GB for a small to medium environment
- Dual Octo core, 32GB RAM and 100GB disk for high numbers of sites
What technology is InSite built on?InSite runs on a Linux operating system. We normally use 64-bit CentOS 5, and we can use 64-bit Redhat Enterprise Linux (RHEL) 5 as well.
We use the open source database PostgreSQL.
To help with potential high availability/clustering applications, we use a group communications system called Spread (http://spread.org/).
The codebase is mainly C++ for the core functionality, and Perl and Javascript for the web-based UI.
We use libpqxx (http://pqxx.org/development/libpqxx/) for connecting to PostgreSQL from C++ and the Perl DBI (http://dbi.perl.org/) to connect using Perl.
We use Apache HTTP server (http://httpd.apache.org/), with various performance modules including Apache::DBI for persistent database connections, and MOD_Perl (http://perl.apache.org/) for a persistent Perl interpreter.
We also use pgbouncer (http://wiki.postgresql.org/wiki/PgBouncer ) which is a lightweight connection pooler for PostgreSQL. The database has been extensively tuned for speed and performance.
We use the standard Linux Net-SNMP libraries.
What browsers can be used to access the InSite UI?InSite provides a web interface which has many advantages for accessibility and maintenance. We use the latest HTML5 technologies and therefore need recent HTML5-compliant browsers. Any HTML5 compliant browser can be used for accessing the InSite dashboards. The management UI requires IE (Internet Explorer) version 9 or later.
