Softline Group has completed a migration project for a Russian power generation company, replacing the legacy MS Exchange 2010 email system. The transition was part of a broader import substitution initiative aimed at securing corporate communications.
The project involved deploying VK WorkMail On-Premise and the VK Teams platform in a fault-tolerant cluster configuration. Softline specialists integrated the new systems with existing AD/LDAP directories and established a coexistence mode with the old software to ensure a seamless transition for end users.
To support the infrastructure, the team implemented a MinIO-based object storage system with data replication. Network traffic is managed by Keepalived, while Keycloak serves as the bridge between the communication platform and the corporate identity management system.
The final architecture features a secure environment with segmented network zones, including internal and DMZ segments. The deployment ensures high availability through application clustering, data replication, and load balancing, while maintaining familiar email workflows for the client.
