I wanted to compare the prices to the current prices:
That puts us up to €26,97 a month on our six machines so far.
The cost for this same calculation has risen to €41,94 for the exact same configuration (3x CX23, 3x CX33).
These two additional load balancers (lb11) bump up the price with €5.39/mo.
lb11 is now €7,49 x 2 = €14,98
A public IP address costs €1,70/mo which adds an additional €10,20
According to Hetzner's pricing page, this is now free on CX23, but costs an additional €0,50 on CX33.
...making our total €47,95/mo pre-VAT
€41,94 + €14,98 + €1,50 = €58,42, or roughly a 22% increase. Still over €10 cheaper than the prices the article quotes for a managed cluster on AWS/GCP, but as someone that does this for a living, €10-15 extra is a very negligible price to pay to avoid the amount of headaches you'll get by having to manage and upgrade the cluster yourself.
