Went with GreenCloudVPS's "elastic cloud shared" plan in January. Marketing promised "seamless scaling" and "distributed redundancy." Six months later, rewriting this post because I finally understand what I bought.
The problem: every request hits a different node. Session files vanish between clicks. Upload a file, 404 on refresh. Route via their Anycast adds 8-12ms vs my old InterServer VPS, but that's not the real issue.
$ for i in {1..5}; do curl -sI https://greencloudvps.com | grep -i "X-Served-By"; done
X-Served-By: node-pdx-47
X-Served-By: node-atl-12
X-Served-By: node-pdx-03
X-Served-By: node-ord-89
X-Served-By: node-pdx-47"Elastic" meant they spin containers per-request, not that my plan scales. My bad for not reading. Traditional VPS: one box, predictable sessions, 0ms node hopping.
Updated my review. They updated their sales page too. Coincidence?
