The complete suite of software can be hosted on a minimum specification machine such as an Azure B2s with Web Edition SQL. The B2s cost with OS and SQL licencing was $65 / £45 per month based on the Azure Pricing Calculator in November 2021.
The specifications are:
- 2 CPUS
- 4 GB Memory
- IIS
- SQL Web Edition
This will comfortable run the entire suite of database, robot, and dashboard.
We have also tested a large client installation performing ~50,000 individual checks across ~4,000 configured checks each day. This included a mix of uptime checks, content checks, domain checks, TLS certificate checks, and DNS record checks. The client was using an Azure B2ms at a cost of $95 / £70 per month.
