Description:

Writing code to use VMware vSphere tags can be challenging in large-scale environments. In this technical paper, we discuss the scalability limits of tags and give some tips and tricks for writing performant tagging code in Java or PowerShell. This paper is an updated version of the tagging whitepaper for the vSphere 7.0 U2 release. We describe some performance improvements (relative to 7.0 U1) in tag association APIs and show data regarding Enhanced Linked Mode performance. The limits for the number of tag associations vSphere can support are the same as for 7.0 U1, although the performance for some APIs is improved.
