Invest in Azure Reserved VM Instances (RVIs): Companies that plan to use the cloud long-term must use reserved instances. These are more significant savings based on commitment and upfront payment. Because RI savings is as high as 75%, this is crucial for optimising cloud costs.
Since RIs are only offered for a year or three, it's important to evaluate your past use and make sufficient plans for the future. The Microsoft's Azure Reserved VM Instances (RIs) buying guide are also options for getting RIs.
Benefits of Spot Instances: Despite being very different from RIs, Spot Instances can help you save more money in Azure costs. If the price is right, spot instances can be purchased for immediate use at auction.
However, opportunities to buy Spot Instances may pass quickly. Thus, they work well in particular computing contexts like batch operations and easily cancellable workloads. All cloud cost management plans should include instances because tasks like these are common in large companies.
