The shift to public cloud providers, like AWS, offers many advantages for companies. This means trading the old model of using heavy CapEx (capital expenditure) to invest in data centers, and servers upfront to a variable expense model, which is pay-as-you-go.
However, organizations often forget to evolve strategies when shifting to the cloud. Rather, they continue to operate new services with the old mindset of traditional data centers. Because of this practice, they lose money. To maximize the cost optimization model of AWS, companies need to plan accordingly and leverage the many tools AWS provides for monitoring resource usage.
