Choosing and Installing 1C-Bitrix Enterprise Edition
"Enterprise" is the top tier of the 1C-Bitrix lineup. People choose it not for a specific feature list (most are available in "Business"), but for infrastructure capabilities: clustering, web cluster, scaling for high load, and extended capabilities for large portals.
What Distinguishes "Enterprise"
Web cluster. Bitrix Web Cluster distributes load across multiple web servers with a shared database. Sessions are stored in memcached, static content on separate servers, PHP handles only dynamic content. For a large store with holiday peak loads—it's the only way to scale horizontally within Bitrix.
Database backup. Built-in MySQL Master-Slave replication support: read requests are distributed among slave servers. Configured in /bitrix/php_interface/dbconn.php via DBHost, DBSlaveHosts parameters.
Extended access control. Granular permissions for site sections, infoblocks, admin interface. Critical for large corporate portals where different departments manage different sections.
Unlimited websites in multi-site configuration (younger editions have limits).
When "Enterprise" Is Needed
- Website with traffic from 50K unique visitors per day
- Large corporate portal with hundreds of editors
- Multi-site structure with dozens of sites
- Requirement for hot backup (site must not fail if one server goes down)
For a medium online store with traffic up to 5-10K visitors per day, "Enterprise" is overkill. Infrastructure capabilities are needed when "Business" on a good server already hits the ceiling.
Installation Specifics
When deploying "Enterprise" in cluster configuration, installation is more complex: multiple servers, shared NFS mount point for /upload/ and /bitrix/cache/ (or S3-compatible storage), load balancer configuration (Nginx upstream, HAProxy).
Basic single-server installation—standard procedure: 1-2 days. Cluster configuration with 3+ servers: 1-2 weeks including failover testing.
