Understanding flavors

This article explains the DataTenant cloud compute flavors.

'Flavors' in the DataTenant cloud describe the virtual hardware that will be allocated to a virtual machine/instance. For example, a 'small' flavor might mean a virtual machine will have 2 virtual CPUs and 4 GB of virtual RAM. A 'large' flavor might mean a virtual machine will have 8 virtual CPUs and 16 GB of virtual RAM.

Understanding flavor tiers and versions

In the DataTenant cloud, each flavor 'size' is also broken out by tier and version. Our three tiers are 'blue', 'yellow', and 'red'. You should choose your tier based on how often you feel your instance CPU will need to the majority of its available processing power:

• Blue Tier: Your instance will mostly sit idle but will need occasionally to burst to high levels of CPU consumption. This is the least expensive tier.

• Yellow Tier: Your instance will sit idle for part of the day but will burst to high levels of CPU for prolonged periods of the day. This is the middle tier in terms of cost.

• Red Tier: Your instance will using most or all of its allocated CPU power for the majority of the day. This is the most expensive tier.

Choosing a tier that is underneath your instance's needs may result in bad performance during peak periods when the instance requires maximum CPU power allocation. Tiers can be changed at will, however, by following our Changing flavors article.

In addition, flavors will have a version indicator, like v0, v1, v2, etc. These version numbers correspond to hardware generations in the back-end infrastructure. Higher version numbers indicate new generations of hardware. Higher versions will often (though not always) be more expensive than lower versions.
