What an uptime promise really allows, how software is tested, what to check before buying business software, and every software and development guide on FintechZoom Pro.
What does "99.9% uptime" really mean?
Hosting and software contracts often promise an uptime percentage in a service level agreement (SLA). Each extra "nine" cuts the allowed downtime by ten, and usually raises the cost. Google's Site Reliability Engineering book explains why 100% is rarely the right target: users' own devices and networks are less reliable than that.

SLA calculator
Allowed downtime
Per year8.8 hours
Per month43.8 minutes
Per week10.1 minutes
Per day1.4 minutes
Based on an average year of 365.25 days. Check how the SLA defines downtime and what credits you get.
Levels of software testing
Unit tests
Check small pieces of code in isolation. Fast and cheap, so teams write many of them.
Integration tests
Check that components, APIs and databases work together. See testing APIs with cURL.
End-to-end tests
Drive the real interface like a user would, with tools such as Selenium. Slower and more fragile. See Selenium with Java and self-healing test scripts.
Shift left
Testing earlier in development, often in the cloud, so bugs are cheaper to fix. See shift left in the cloud and test planning.
Choosing business software
- Fit: list the must-have workflows before looking at vendors; extra features add cost and complexity. See avoiding software bloat.
- Integration: check it connects to the tools you already use. See AWS data integration and Power Apps for Office 365.
- Security and accessibility: ask about security practices (OWASP, CISA Secure by Design) and accessibility (WCAG). See our accessiBe review.
- Total cost: licences, setup, training and switching costs. See researching software online.
