How Scalability Works in SolarWinds Observability Self-Hosted

Cheryl Nomanson, SolarWinds staff technical trainer, provides a comprehensive overview of SolarWinds architecture and scaling options for self-hosted deployments. She explains the centralized deployment model starting with a single SolarWinds server that handles polling, web console, and database connections. The presentation covers key scaling indicators including polling thresholds that warn users at 85% capacity and alert at 100%. She demonstrates how to add up to 100 polling engines per server and additional web servers to handle more concurrent users. The session also covers high availability options for both polling engines and main servers, and introduces distributed deployments with multiple SolarWinds servers across different sites. For distributed environments, she explains the Enterprise Operations Console (EOC) that provides consolidated views across multiple sites. Throughout the presentation, she emphasizes that scaling decisions should be based on actual performance metrics rather than arbitrary entity counts, and references more detailed training available through SolarWinds Academy classes.
