We’ve looked at methods to reduce costs within Azure. We may experience situations where a slight increase in Azure costs will benefit us to help protect our resources and customers when it involves security or other critical updates. When we consider these situations, we must keep up-to-date with the latest patches, updates to development libraries, as well as the possible effects of these updates to our existing code. Likewise, related to resource usage, a resource may be unused or seldom used by a percent of our customers that we keep when we’re ready to switch all our customers while we make the appropriate upgrades to our resources to help with costs. We’ll look at some techniques that we can use to manage the challenge of critical updates while also keeping costs down, or putting costs into a context about what may be more expensive.

To reduce Azure costs on unused and unnecessary resources, we should design with prevention in mind – considering whether we want to commit to reserved use or test with a pay-as-we-go model. We may experience situations where we already have many resources, but are unsure of their use – are these consistently used, sometimes used, never used? Before we can answer whether an unused resource (or what appears to be an unused resource) is unnecessary, we have to determine whether it’s used. In this tip, we’ll look at this challenge.

Two of the more challenging causes of an increase in Azure costs are unused and unnecessary resources. Unused and unnecessary resources may not always be the same, even though they can overlap. If we know the difference between these resource categories or when these resources categories overlap then we will see improvements in preventing these from adding to our costs. In addition, when we think about unused resources, we should consider options that we have with Azure to optimize for these, as an unused resource may still be necessary sometimes. In this tip, we’ll look at these topics to assist us with reducing our Azure use.
