Global Presence Now on the Scene
The Liftr Index is a live, ever changing tool meant to compare the major cloud providers on a variety of scales. On occasion, the metrics and statistics that make up the Index need to be adjusted to account for new market information as well as to make the tool more useful and accurate. This week, several changes were implemented, including changing the formulas of several metrics and adding a new category, Global Presence.
The most impactful change this week is the addition of the Global Presence category, including a new Redundancy metric, as well as moving Regions and Zones from the Adaptability category into the new segment. This was designed to display changes to the regional offerings of each major provider more appropriately, as well as more correctly reflect additions of new regions and zones going into the future. The Adaptability category will be otherwise unchanged, still including Count of Services, Transfer Cost, and Marketplace Size as variables.
Change the Math, Change the Perspective
A small change to the way the Uptime metric will be calculated means that the Reliability category will now reflect changes more drastically as the providers approach 100% uptime. Now, small fluctuations in overall provider liability will be more detrimental than they have been up until this point. The purpose of this change is to display cloud outages as they occur via the Reliability score, and will allow users to see correlation between consistency of service and the Index values. A similar change has been made to the Gartner User Review metric, which pulls its scores from verified feedback of cloud customers.
Lastly, the Use Case Comparison metric is being altered to a relatively smaller numerator, enabling the visualization to be a bit more clear. Like the changes to Reliability and User Review, this will allow more subtle changes in the marketplace to be revealed more obviously.
All changes apply equally to all providers, meaning that the true relationship between each one is unchanged. These new methods have been carefully developed and tested by the Liftr Index team to provide a better user tool. These updates will be monitored closely going into the future, so keep a look out for future updates and iterations as we continue to strive to bring you the very best in cloud data.
