I spent a handful of minutes erasing the SCM information from the architecture diagram. I then tidied up the leftover image; reducing the size of boxes, redrawing arrow lines, etc. I wasn't able to attach the PNG version; it is 214KB, larger than the attachment limit. Here is a lossy version. Please advise how I might supply you with the PNG version, should you wish to use it on the website. If you do not want it - that is fine too; it might be useful and/or interesting to continue to show the SCM design.
Thanks,
Lexi
