Smoke testing is a term used to describe the testing process for servers after patches are applied.
The process typically involves making sure servers are rebooted in the right order, making sure they have completely rebooted, restarting applications in the right order, and then testing to be certain everything is working properly when users return to work in the morning.
This typically takes 30 minutes per server, depending upon your environment.
PCs are not typically smoke tested, or if so, not all of them.
Estimating an average time for patching servers and PCs can be a bit tricky. It can vary from one month to the next, depending upon the number and complexity of the patches released by your software vendors. You must consider all versions of operating systems and have a complete inventory of all your application software to do this job correctly. Our experience has shown that manual patching of systems takes on average of about 1.5 hours each.
This is a basic cost calculator for you to compute your typical monthly cost for patching your servers, PCs, laptops, tablets and associated application software. It also forms the basis for you to begin calculating your Return on Investment for software patching, or for comparison with alternatives to the manual process of patching operating systems and application software—such as Patch Management as a Service, also known as Vulnerability Management as a Service.
