For example – the following filter: https://prices.azure.com/api/retail/prices?$filter=serviceName eq ‚Virtual Machines‘ and priceType eq ‚Consumption‘ and endswith(armRegionName, ‚europe‘) and (startswith(skuName, ‚D‘) or startswith(skuName, ‚E‘) or startswith(skuName, ‚F‘) or startswith(skuName, ‚M‘)) and endswith(skuName,‘ Spot‘) displays the price for only „VMs“ with specific properties: no Reservation in „.*europe“-Locations with Types „D.*“ or „E.*“ or „F.*“ or „M.*“ Spot-Intances but – if you don’t want „Spot“ Instances, you’d guess this filter-Statement: https://prices.azure.com/api/retail/prices?$filter=serviceName eq ‚Virtual Machines‘ and priceType eq ‚Consumption‘ and endswith(armRegionName, ‚europe‘) andRead More →

more than ten years later (IEEE 802.1ax-2008), but everybody calls it 802.3ad and serverguys still prefer static bonding with round-robin distribution [without telling network admins about that decision] to confuse (or tear down) ethernet-networks. What a stupid default: default bond0 interface with balance round robin mode Awsome 🙂 FWM-2-STM_LOOP_DETECT How a single server affects vMotion, SLB-VIP-Mobility, First-Hop Redundancy-Protocols (VRRP, HSRP you name it) in 2019.
