'''Video summary:''' New-engineer onboarding presentation given by Biswajit Banerjee covering Tetra's company history and full technology breadth (not a client-specific support session like most others). History: founded 1995 by four co-founders (the name "Tetra" = four), spun out of a company called PCL, started in hardware sales and Novell Netware deployments in the pre-internet era, moved into Linux around 1997-98, built early internet/mail/proxy/Samba solutions for client offices, weathered the Y2K migration, and evolved its mail-hosting stack over the years from sendmail to qmail to Postfix/Zimbra (Zimbra since ~2006-07). Second half covers the company's current scope: hybrid Zimbra + Microsoft 365 deployments, ELK and Prometheus/Grafana monitoring, their own in-house CloudStack private-cloud platform (a major current growth focus), Kubernetes/microservices/DevOps work, their OTRS-based "iHelpDesk" ticketing product, document management via Nextcloud/Alfresco, and custom LAMP-based government/enterprise software projects (notably an "online building plan" application used at scale in West Bengal, Punjab, and Haryana, integrating with third-party scrutiny software and pitched internationally). Closes with a client-name overview spanning large enterprises (Adani, ICICI Bank, NTPC) and SIs (Infosys, HP), framed as context for why new engineers need to stay comfortable picking up new technology rather than specializing narrowly.
