Azure Archive Storage is used for less important data, where an organisation is happy to wait – perhaps hours – for access to their data. This means it is significantly cheaper than regular Azure storage.
Microsoft have announced that prices have dropped “by up to 50 percent in some regions” – although they haven’t given more precise info as to what reductions have taken place in what areas. That said, if you’re using this – you should see a reduction in your next cloud bill…or at least that section of it!
