From faf98c0623d6846804f5e5f03b586bc5efb89cc8 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Fabiano=20Fid=C3=AAncio?= Date: Thu, 14 Sep 2023 20:14:00 +0200 Subject: [PATCH 1/3] ci: Reduce the size of the AKS VMs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We do **not** need a very powerful machine for our tests, as we're not building anything there. The instance we switched to (Standard_D2s_v5) still has nested virt available, as shown here[0], but has half of the amount of vCPUs / Memory, which should be fine only for running the tests, costing us basically half of the price[1].
