The Five Pillars of Cloud Cost Optimization: Why They Matter & How to Apply Them

 

The companies in the modern day world are cognizant of the reality that the utilization of clouds is linked to the challenge of agility as well as cost. Without a disciplined approach, cloud bills can go out of control. There is Cloud Cost Optimisation of five pillars. These pillars act as a guideline whereby organisations achieve the performance, flexibility and financial performance. In CMARIX, we have noticed that these systematic approaches to the work allow the teams to develop on a sustainable basis and provide the physical business contribution.

Pillar 1 - Rightsizing

Definition Rightsizing means the act of matching the resources (compute, storage, data bases) to the actual work load requirement, but not over-provisioning.

Benefits:

Eliminates wasted spend.

Improves system efficiency.

Determines capacity of scale at its location.

Tools & Best Practices:

In AWS Cost Explorer, Azure Advisor or GCP Recommender, one can use underutilised resources.

Adopt autoscaling policies.

Periodically test VM sizes and database levels.

In CMARIX, we advocate the right sizing as the centre of the cloud cost optimisation policies and business is only paid as much as it is actually used.

Pillar 2 - Elasticity

Elasticity is the feature of cloud computing that enables a dynamically sizable increase and decrease of resources based on the need.

Approaches:

Dynamic Scaling: Respond to bursts of demand in real-time (e.g., e-commerce flash sales).

Planned Scale Down: During the night or weekends when there is less work load, scale down.

Workload-Sensitive Management: Align resources with business priorities.

By using elasticity, organisations will be able to pave the advance techniques cloud cost savings on the cloud without affecting the performance of their applications.

Pillar 3 - Instances Reserves & Pricing Models

The cloud vendors are rewarding in terms of commitment. RIs, Savings Plans, and Spot Instances can be used to save a lot of money in case they are implemented correctly.

When to Use:

RIs and Savings Plans: Workloads in long term (databases, core apps).

Spot Instances: There is no importance of fault-tolerant workloads like CI/CD pipelines.

On-Demand: To experiment, test or short term projects.

We can help businesses to find workload trend, fit them with correct pricing models at CMARIX where we can help create long term value but never make the commitment to inefficiency.

Pillar 4 - Ongoing Review

Optimisation is not a one-time project, but it is a continuous job.

Key Practices:

Usage Monitoring: This is to monitor usage on a daily/hourly basis to detect spikes.

Cost Attribution: Attribute all resources (tag) by team, department or feature.

Anomaly Detection: Consumption machine learning-based information (AWS Anomaly Detection, Azure Cost Alerts).

Cloud Cost Optimisation is maintained at a constant level of tracking of the dynamic business objectives and prevents bill shock.

Pillar 5 - Selecting the right Pricing Model

On-Demand, Spot and Reserved: It is either cost-efficient or flexible between them.

On-Demand: flexible, but the most costly.

Reserved: Discounted rates with first or longer trappings.

Fault-tolerant spot: Workloads are heavily discounted.

According to CMARIX, organisations should have a hybrid pricing system in which the approaches are integrated depending on the work nature. This leads to power and cost maximisation.

Case Studies: The practice of the Five Pillars

SaaS Startup: 22 months was saved with the rightsizing of Kubernetes clusters and using Spot institutes in CI/CD.

Enterprise Retailer: Adopted the elasticity in the seasonal sales that saved the enterprise millions of money in the unutilized infrastructure spending.

FinTech Firm:Constant check showed that there were unused RIs, which was why it was possible to redistribute it and to save 15 percent related to it.

All these illustrations will lead to the fact that the five pillars are helpful when introduced in a systematic way.

Challenges & Common Pitfalls

Coming up short in future expansion by overcommitting to Reserved Instances.

Wrong tagging, therefore the cost can hardly be attributed.

Treating optimisation as an action and not a process.

Lack of collaboration between the engineering and finance departments.

Conclusion & Action Steps

The five pillars of Cloud Cost Optimisation which include right sizing, elasticity, reserved instances, continuous monitoring and pricing models provide an effective model in addressing the cost without innovation being a victim.

Action Steps:

It should start with the rightsizing and tagging policies.

stratification of the dynamic elasticity loads.

Commit to RIs or Savings Plans containing known work loads.

Constant control is to keep savings.

Periodically revise pricing models in the light of changes in your workloads.

We help businesses at CMARIX to implement these cost optimisation strategies in their DevOps and FinOps. Under these new ways of saving costs in the cloud, not only can organisations control costs, they can also provide agility in order to innovate faster.
