The short version

  • Only Microsoft SQL Server has a free tier, so it costs nothing to try first.
  • Each has a real cost: Microsoft SQL Server licensing and on-premises deployment costs are high compared to open-source alternatives, with Enterprise Edition exceeding $60,000 for minimum core requirements; Wattwatchers EMS requires hardware installation at each monitoring point, increasing total cost of ownership
  • They diverge on capability: Microsoft SQL Server covers T-SQL, Wattwatchers EMS covers Real-time monitoring.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Microsoft SQL Server

  • Licensing and on-premises deployment costs are high compared to open-source alternatives, with Enterprise Edition exceeding $60,000 for minimum core requirements
  • Performance monitoring toolset is insufficient for hybrid cloud environments requiring real-time analytics across multiple deployment types
  • Heavy I/O resource consumption can saturate disk volumes and degrade performance when processing large transaction workloads
  • Always On availability groups with up to 8 secondary replicas are limited to Enterprise edition only; Standard supports only basic availability groups with 2 replicas
  • CPU and memory scaling is capped at 4 sockets or 32 cores on Standard edition, limiting deployments requiring higher compute capacity

Wattwatchers EMS

  • Requires hardware installation at each monitoring point, increasing total cost of ownership
  • Built for small to medium portfolios; scaling to large portfolios may present usability challenges
  • Limited to energy monitoring; not a comprehensive building management system
