Cloud cost optimization is the process of lowering your entire cloud spending by determining mismanaged resources, eliminating waste, reserving capacity for more significant discounts, & correctly sizing computing services to scale.
The cloud enables businesses to scale indefinitely and reduce IT expenses by charging only for the resources they use. However, the reality of Amazon Web Services (AWS) and Microsoft Azure pricing is that cloud users are charged for the resources they purchase, regardless of whether they utilize them.
What is Cloud Cost Optimization?
Cloud cost optimization is the ultimate consequence of effective FinOps—cloud financial management—a collection of business strategies that connect control over the cloud IaaS variable expenditure model to financial responsibility.
Optimizing cloud expenses successfully needs your business to understand two key areas:
Intelligent Cloud Service Procurement
Utilizing low-hanging savings possibilities such as AWS Savings Plans and capacity reservations such as Amazon Reserved Instances
Intelligent Cloud Capacity Optimization
Matching your cloud workloads intelligently to the best instance and resource configuration
Best Cloud Cost Optimization Strategies & Practices
Identify unused or unconnected resources
The simplest way to minimize cloud costs is to discover unused resources. An administrator or developer may “spin up” a temporary server for a job and then fail to take it down. An administrator may also fail to remove storage linked with terminated instances. This happens often in IT departments.
So, an organization’s AWS bill, as well as the Azure bill will include costs for resources not utilized. To reduce cloud costs, discover and eliminate underused and disconnected resources.
Recognize and Consolidate Unutilized Resources
The next step in cloud cost optimization is to manage idle resources. An idle computer instance’s CPU utilization ranges from 1% to 5%. Getting charged for the whole computer instance is a huge waste. Finding these instances and consolidating computing workloads is important for cloud cost control.
Historically, managers preferred low utilization over a spike in traffic or a busy season. Inefficient and expensive expansion of a data center’s resources. Instead, the cloud offers autoscaling, load balancing, and on-demand processing capability.

Make Use of Heat Maps
Heat maps are critical tools for optimizing cloud costs. A heat map is a graphical representation of the peaks and troughs of computing demand. This information may be very beneficial in setting start and stop timings for cost-cutting purposes. For instance, heat maps may be used to determine if development servers can safely be turned down on weekends.
While managers may manually shut down servers, a preferable alternative is to use automation to plan instance start and stop times, thus minimizing expenses.
Appropriate Scale of Computing Services
The process of rightsizing computing services includes evaluating them and optimizing their size. You may optimize servers for memory, database access, computation, graphics, storage capacity, and throughput, along with server size optimization.
If required, Rightsizing tools may also suggest modifications across instance families. Right-Sizing contributes to more than just cost savings in the cloud; it also aids in cloud optimization or maximizing the performance of the resources you pay.
Invest AWS Reserved Instances (RIs) or Azure Reserved Virtual Machine Instances (VMIs) (RIs)
Enterprises with a long-term commitment to the cloud should invest in RIs. These are higher discounts offered in exchange for an upfront payment and a term commitment. Savings from RI may reach up to 75%, making this a must-have for cloud cost optimization.
Given that RIs may be purchased for one or three years, it is critical to evaluate your previous use and plan appropriately for the future.
Capitalize on Spot Instances
Spot Instances are fundamentally different from Reserved Instances, yet they may help you save more money on your AWS or Azure expenditure. Spot Instances are up for auction and may be bought for immediate usage if the price is appropriate.
However, chances to purchase Spot Instances are fleeting. They are ideally suited for specific computing scenarios such as batch tasks and jobs that may be rapidly canceled. Due to the prevalence of such jobs in big companies, Spot Instances should be included in all cloud cost optimization efforts.
Consider the advantages and disadvantages of multi-cloud computing vs. single cloud computing.
Certain businesses actively seek multi-cloud solutions to prevent vendor lock-in. While this is a viable approach for improving availability and uptime, these businesses risk missing out on bulk savings offered by a single cloud provider.
The administrative burdens associated with switching platforms, paying for network traffic across clouds, and educating employees on various clouds may exceed the potential financial savings associated with a multi-cloud approach.
The optimization of cloud cost does not have to be hard, but a disciplined approach creates good rights-raising processes and pushes insights and actions continuously by means of analytics, in order to decrease your cloud cost.
