Another trap is not understanding the performance levels of the Azure compute layers. We frequently see customers purchasing premium storage where they could have more appropriately chosen, and paid considerably less, for standard storage.
There are several configuration options in Azure which impact the data replication points (including LRS which replicates your data at the same data centre, through to GRS which replicates your data in different geographic locations). It’s confusing, so we’re never surprised when customers select the wrong storage. You have five types of storage to choose from, each of which then offers a further five options for redundancy types. It’s easy to end up paying for additional storage and points sitting in Azure which you don’t need.
And if you make the wrong decision from the outset? For example, choose the most expensive storage option (ZAGRS), and realise your mistake six months down the track? You’re stuck with it until the end of your license period.
Additionally, Azure offers two types of disk storage: Standard hard drive and SSD hard drive (flash memory). Choosing the wrong one can cost you dearly. For example, adding 512gb disk to a standard hard drive, it will cost you $34 a month. But if you add the same 512gb to an SDD drive, you’ll pay $52.
As Azure evolves, Microsoft brings in more computer types - and different pricing to match. If we compare the F8 server (eight cores, 60gig memory and 128gig of temporary storage) with a D8, which has double the memory and the same CPUs - it would cost you $20 less a month. Or if our review shows you are underutilising your device capacity; we can double your savings again with an F4 with its four cores and 60gig of memory.
And a trick for beginners: If you’re committed to Azure for the long-term, you can reserve the storage you need and earn a discount from Microsoft.
