What is Cloud Cost Optimization?

The whole idea of Cloud Cost Optimization is to reduce the cost of your cloud services and achieve the same (or even greater) level of performance. It is the sum of tracking, quantifying, and managing your cloud spending to ensure that you are getting the most out of each dollar that you spend on cloud services.

Conventionally, this was concerned with the reduction of waste. One of the best analogies for cloud computing cost savings would be switching off the lights in the rooms that you do not use, i.e., getting rid of underused or forgotten resources and streamlining your purchases (e.g., by pre-reserving capacity).

Nowadays, though, with the next generation of services such as Kubernetes and serverless becoming the norm in companies, Cloud Cost Optimization has become far more of an architectural optimization. Infact State of FinOps report found that 'Reducing waste' is now the #1 key priority for FinOps practitioners, overtaking all other concerns for the first time.

Advantages of Cloud Cost Optimization

It is not only about saving a couple of dollars to get a hold on your cloud costs. It has many advantages, so if you do it right, it can ripple across your entire organization:

  • Precise Forecasting: Improve your cloud spend forecasting, planning, and budgeting, stay prepared by the end of the month.
  • Empower Your Teams: Provide your teams with real cost visibility. This enables them to visualize the immediate cost-effectiveness, and they make smarter choices.
  • Higher Profitability: Find out which parts of your solutions are bleeding money and could be re-architected for better profitability.
  • Smarter Decisions: Make informed choices on your pricing, decommissioning unused features, and resource allocation.
  • Automatic Savings: Don't need to work hard, just get a tool and enjoy automated load balancing, autoscaling, capacity reservations, and Spot Instances.
  • Service Optimization: Find the optimal (and least expensive) services to apply to each application.

How to Make a Cloud Cost Optimization Strategy?

Almost all companies have governance, security, and compliance plans. Why not include a Cloud Cost Optimization plan in that one? In this way, you will have control over your infrastructure and the charges it will charge you prior to occurance.

A good strategy often contains the following points:

  1. Uniform Tagging: Have a standard and transparent labelling (tagging) system that all people in the company use. This cannot be compromised on cost allocation.
  2. Monitoring & Alerting: Install systems that track your expenditure and automatically notify the appropriate departments (not only the finance department) when costs are high or budgets are being compromised.
  3. Continuous Optimization: Develop a system of cost evaluation and optimization that will be done continuously. It is not a one-time activity but rather a cycle.

What to Look for in your next Tool?

Knowing what to look for to make sure you get a long-term match is good. The following are some of the main criteria that should be considered:

  • Automation vs. Recommendations: Does the tool only report what is wrong (e.g., this VM is oversized) or does it fix it automatically? Numerous tools provide recommendations, but the most significant savings are made in true automation.
  • Kubernetes & Container Support: The cloud is going to containers. When your tool is unable to look inside your Kubernetes clusters to inform you of the cost of a particular namespace or deployment, you are leaving a massive portion of your bill unclaimed.
  • Multi-Cloud Visibility: Many companies are not fully in a single cloud. You require one dashboard that would bring in data from AWS, Azure, and GCP (and possibly on-prem) to provide you with the complete picture.
  • FinOps & Reporting: Does the tool assist you in showback (demonstrating groups their expense) and chargeback (truly billing divisions)? Does it offer role-specific dashboards, such as for engineers, finance, and leadership?
  • Ease of Use & Integration: How difficult is it to install and maintain? Is it compatible with the tools you already have, such as Slack, Jira, and your CI/CD pipeline?
  • Pricing Model: Take caution here. Other tools will take a percentage of your savings, and others will take a percentage of your overall cloud bill (including that which they do not control). Find a model that is fairly scaled.

The 15 Best Cloud Cost Optimization Tools of 2026

The tools are so numerous, and not all of them are created equal. Others are reportable, others are automatable, and others are hyper-specialized (such as Kubernetes).

We will have a look at the most effective ones to enable you to maximize your productivity and reduce your cloud bill.

1. Costimizer

Costimizer Dashboard

Best in: Autonomous, Agentic AI-based optimization and proactive governance.

First up is Costimizer. This isn't just another reporting tool, Costimizer is the most reliable cloud cost optimization tool out there. Its a next-gen platform that uses Agentic AI to actively manage your cloud spend, backed by a hands-on, expert team.

It’s built for teams who want to move from recommendations to automation. The AI gives you personalized recommendations that show clear trade-offs, like "Option A saves 30% with zero performance risk. Option B saves 50% but may increase read times by 5%." You set the rules.

Plus, you're not alone. Costimizer provides incredible, collaborative team support (think shared Slack channels, not just tickets). You can even get a dedicated FinOps team assigned to your account, acting as an extension of your own staff to proactively manage your spending.

Best features

  • Agentic Optimization: Autonomous agents safely handle rightsizing, Spot Instance management, and automated storage cleanup (deleting unattached disks, old snapshots, etc.).
  • Group-Buy & Guaranteed Savings: You "group buy" with other fast-growing companies to get the buying power of a mega-corporation. Costimizer leverages this exclusive feature to give you guaranteed cost reductions you couldn't get solo.
  • Personalized "Trade-Off" Recommendations: Get AI-driven options that show the real-world impact of each choice (e.g., "save 20% at 0% risk" vs. "save 40% at 5% risk").
  • Proactive Budget Enforcement: Establish budgets and quotas on a team, project, or application level and have them automatically enforced by Costimizer agents.
  • Multi-Cloud Resource Inventory: One integrated view to monitor all your resources in all your cloud providers, and orphaned resources are a thing of the past.
  • Engineer-Centric Dashboards: Offers engineers actionable, transparent cost data that is easy to understand and is presented in their workflows to enable engineers to see the cost implications of their work.
  • Advanced Kubernetes Visibility: Splits Kubernetes costs by cluster, namespace, deployment, and pod, so you finally know what is driving your container costs.

We hear one pain point from teams all the time, especially when their cloud footprint grows without guardrails.

Our cloud bill is a black box. is there an ai finops tool that can proactively identify and automatically downsize idle resources across aws and gcp?

Because Costimizer has agentic resource optimization actively cleans up your cloud environment. It downsizes underutilized instances, shuts down abandoned ones, removes obsolete images, clears duplicate storage, and flags idle resources without waiting for manual review. Everything you see in that dashboard is automatically taken care of by its agent.

Current limitations

Being a relatively new and high-tech platform, it may not yet cover some advanced use cases. However, they have a dedicated team to onboard you, offer a completely free trial, and rapidly roll out advanced features that only a few customers typically require.

Pricing

Trial Plan: Includes cost visibility and resource inventory for up to $10,000 in monthly spend.

Pro Plan: Starts at 2.5% of your monthly cloud spend. Includes all optimization and automation features.

Enterprise Plan: Custom pricing for large-scale deployments, premium support, bespoke agent configuration, and the dedicated FinOps team option.

2. CloudZero

Cloudzero Dashboard

Best use: Granular cost per unit intelligence.

CloudZero is not an ordinary cost tool. It is a cost intelligence platform that is context-obsessed. It goes beyond merely displaying your expenditure and delves into displaying your reasons, without necessarily being able to tag them perfectly and indefinitely by hand.

It is created to provide engineers and finance groups with a common language. It supports aggregation of data across AWS, Azure, GCP, and even such platforms as Snowflake, Datadog, and Kubernetes. Its super power is that it disaggregates costs into actionable, business-relevant measures such as Cost per Customer, Cost per Feature, or Cost per Team. This allows engineers to view the actual cost of their deployments in real-time and enables finance to know the profitability at a fine-grained level.

Best features

  • Unit Cost Intelligence: Provides unit-cost information that is relevant to your business, and not your bill.
  • Tag-Free Allocation: Can allocate 100% of your spend, even in complex, untagged environments, by analyzing your infrastructure.
  • Engineering-Led Optimization: Provides engineers with cost information in their language (cost per deployment, cost per service) to enable them to make cost-effective decisions.
  • Real-Time Anomaly Detection: Delivers noise-free, context-rich notifications to allow you to correct cost spikes before they become an issue.

Current limitations

It is a high-quality platform that is concerned with Advanced intelligence, and thus, it might be more than a small team (with a simple bill) requires.

It is powerful in multi-service, complex environments; its value may not be so apparent in a simple, single application.

Pricing

CloudZero has tailored prices depending on your annual expenditure on the cloud. Contact them to receive a quote.

3. Cast AI

Cast AI Dashboard

Best use: Automated cost reduction of Kubernetes.

Cast AI is a robust platform that is concentrated on one primary objective, which is to optimize Kubernetes. It is an automated Kubernetes resource analysis, monitoring, and tuning. The most significant of its strengths are practical automation capabilities, including node rightsizing, automated instance selection, intelligent autoscaling, and Spot Instance management.

The platform separates cloud charges at the project, cluster, namespace, and deployment levels, making it easy to monitor the costs of every microservice.

Best features

  • Advanced Kubernetes Automation: Chooses the best resources on-the-fly, saves money with autoscaling and rightsizing.
  • Intelligent Autoscaling: Scales the number of pod replicas automatically according to workload requirements, and thus you only pay for the amount that you utilize.
  • Efficient Bin-Packing: This is an automated bin-packing that optimizes savings by loading workloads onto the minimum number of nodes.
  • Granular Cost Breakdown: Provides explicit per-cluster and per-node cost information, which makes it easier to monitor multi-cloud costs.

Current limitations

Kubernetes-only: Cast AI is developed to run in cloud-native Kubernetes. It may not be beneficial to organizations that have legacy systems or non-containerized workloads.

Pricing

Cast AI has a free plan for Cost Monitoring. Paid plans (Growth, Enterprise) are based on the quantity of vCPUs and have sophisticated automation capabilities.

Spot By NetApp Dashboard

Best in: Spot Instance savings maximization.

Spot by NetApp (previously Spot.io) is a cloud-optimization service that is good at automated resource provisioning, performance tuning, and cost reduction of infrastructure by intelligent use of Spot Instances.

In addition to Spot, the platform has an Eco feature that automatically manages Reserved Instances and Savings Plans to form a fully automated commitment portfolio. It offers a full-fledged solution to compute spend management, both risk-averse Spot and long-term commitments.

Best features

  • Predictive Spot Instance Management: Operates mission-critical workloads on inexpensive Spot Instances safely by automatically recovering from interruptions.
  • Automation of commitments (Eco): Purchases and administration of RIs and Savings Plans are automated to maximize savings without human intervention.
  • Detailed Cost Breakdown: Provides a finer cost perspective by namespace and workload, that is, compute and storage costs.
  • Intelligent Scaling: Identifies pods that cannot be scheduled and scales infrastructure intelligently to ensure that the performance of applications remains constant.

Current limitations

Compute-heavy focus: The primary savings levers offered by the platform are compute-based (Spot, RIs, Savings Plans). It can miss the opportunities for storage, data transfer, or PaaS services.

Pricing

Spot is a pay-as-you-go service, which usually costs a small percentage of your savings or a charge per resource.

5. Harness

Harness Dashboard

Best use: Adding cost management to your pipeline of CI/CD.

Harness is a high-quality Continuous Delivery (CI/CD) platform. Its Cloud Cost Optimization (CCM) module builds on this by offering cost visibility directly in the development process. It provides the answer to the question, Did my last deployment increase our cloud bill?

Harness provides a detailed view of Kubernetes and cloud expenditure, including used, idle, and unused resources per workload. One of the most emphasized features is the AutoStopping, which automatically turns off non-production resources (dev and staging environments) when there is no activity, and this feature removes waste.

Best features

  • Developer-first visibility: Makes cost data a part of the CI/CD pipeline, allowing developers to visualize the cost impact of any change immediately.
  • AutoStopping: Automatically de-provisions idle non-production resources and restarts them on command.
  • Cost transparency: Gives detailed visibility of Kubernetes by showing used, idle, and unutilized resources per workload and cluster.
  • What-If analysis: Allows users to perform simulations before taking recommendations into action to estimate the possible cost effects.

Current limitations

Low automation: Although AutoStopping is automated, many of the other optimization capabilities are only suggestions. The engineers are still forced to implement changes manually.

Pricing

Harness CCM has a free plan for simple cost monitoring. Premium levels are calculated on your monthly cloud usage.

6. Cloudcheckr

CloudCheckr Dashboard

Best: Security, compliance, and cost on a single platform.

Cloudcheckr (NetApp acquired it) is a full-fledged cloud management tool that began as a cloud security tool. This DNA remains conspicuous, as it is outstanding integrating cost management, security, and compliance. It is an excellent option for an organization, particularly in a regulated industry, that requires all three pillars to be housed in a single location.

The platform provides a comprehensive overview of cost allocation data and shows cloud costs as time goes by. It does hundreds of checks on idle resources, unused instances, and Reserved Instances mismatches. It assists in imposing governance through automated tag-or-terminate policies as well.

Best features

Complete Visibility: Integrates cost, security, and compliance on one platform.

Policy-Based Automation: Automatically implements tag-or-terminate policies to gain more control over infrastructure and allocate costs.

In-Depth Checks: Checks more than 600 idle resources, security-group vulnerabilities, and compliance gaps.

RI/Savings Plan Management: Gives recommendations on purchasing and assists in re-allocating and adjusting the Reserved Instances to optimize their utilization.

Current limitations

Weak Optimization Automation: It is excellent at identifying problems and implementing policies, but its automated optimization capabilities (such as automatic rightsizing) are less powerful, and may need engineering work to act on the suggestions.

Pricing

The pricing of Cloudcheckr is customized and usually depends on the amount of money you spend on the cloud.

7. Kubecost

Kubecost Dashboard

Best use: Granular Kubernetes cost monitoring and allocation.

Another significant Kubernetes player is called Kubecost, and it pursues a slightly different direction compared to Cast AI. Cast AWeis was concerned with automated optimization, whereas Kubecost is obsessed with cost monitoring and allocation. It is the open-source standard of choice to know precisely what is going on in your clusters.

The platform provides insightful information on Kubernetes cost allocation, enabling you to break down costs by namespace, deployment, service, label and so on. This is necessary to have proper showbacks and chargebacks.

One of its most important characteristics is that it can connect in-cluster costs (such as CPU and memory) with out-of-cluster costs of cloud services (such as tagged S3 buckets or RDS databases). This provides you with the entire cost of your application.

Best features

  • Open-Source Core: It is an open-source core that provides flexibility and a robust community to the teams.
  • Hyper-Granular Allocation: Customizable and flexible cost allocation by any Kubernetes concept (namespace, deployment, etc.) with all major cloud providers.
  • Total Application Cost: Attaches in-cluster costs (CPU, RAM) to out-of-cluster expenses (such as databases and storage) to provide a complete, precise cost of a particular team or product.
  • Real-Time Alerts: Gives context-based reports and real-time alerts to assist you in striking an ideal balance between cost and performance.

Current limitations

Monitoring, Not Optimizing: Kubecost is an excellent tool for telling you how your money is being spent. It is not a platform of automation. You will have to extract its Advanced knowledge and make the changes, or combine it with another tool manually.

Pricing

Kubecost has a free-forever plan in one cluster.

Paid plans are priced depending on the number of clusters and provide such features as extended data retention and enterprise support.

Customer Rating and Reviews

G2: 5 out of 5

8. Zesty

Zesty Dashboard

Best Use: AWS Reservations and Savings Plans.

Zesty is an ingenious application that addresses a highly narrow, highly costly issue: Reserved Instances (RIs) and Savings Plans. These are the cloud provider buy-in-bulk discount plans. The problem is, they are rigid. You commit to utilize a specific amount over 1-3 years, and in case you require more or less, you will be paying to use capacity that you are not using.

This commitment is made dynamic by Zesty. It automatically trades RIs on the AWS marketplace in real-time to purchase and sell AWeto to fit your real-time usage. Your cloud commitments have a stockbroker. It also provides Zesty Disk that dynamically reduces and increases disk space according to real-time requirements.

Best features

  • Dynamic Commitment Management: Buy and sell AWS Reserved Instances automatically to exactly match your real-time utilization, avoiding long-term lock-in.
  • AI-Powered Predictions: It uses analysis of usage patterns to predict future needs to ensure you have the best (cheapest) commitment portfolio.
  • Dynamic Storage: Zesty Disk will automatically scale the size of EBS volumes to avoid overprovisioning.

Current limitations

Very Niche Focus: Zesty is a genius at its work, yet it is only applicable to AWS commitments and storage. It does not do rightsizing, multi-cloud, or K8S. It is not a Swiss Army knife, but a scalpel.

Pricing

The prices of zesty are usually a percentage of the savings that it brings to you.

Best use: FinOps and business reporting at the enterprise level.

One of the first and oldest FinOps tools available is Cloudability, which is currently owned by Apptio (acquired by IBM). It is designed to support large organizations that require tracing the complex cloud expenses to individual business units, products, and cost centres.

It does not have the power of real-time automation, but it has a robust reporting and cost allocation. It is an excellent way to consume data in all your clouds (AWS, Azure, GCP) and other tools (such as New Relic or Datadog) and build one cohesive financial model. It enables you to create personalized dashboards and reports to all stakeholders, including an engineer and the CFO.

Best features

  • FinOps Dashboard: One dashboard to all cloud spending, to support high-level financial tracking and business-unit chargeback.
  • Advanced Cost Allocation: Takes in and normalizes tagging and billing data to provide you with a clear business-focused picture of your costs.
  • Anomaly Detection: This is a machine learning tool that helps you identify and be notified about cost spikes that do not fit your usual spending habits.
  • RI/Savings Plan Modelling: This offers advanced modelling to assist you in making the correct long-term commitment purchases.

Current limitations

Reporting, Not Automation: This is not an engineering automation tool, but a financial management tool. It also offers suggestions but does not necessarily implement changes.

Complexity: It is an enterprise-grade tool, and as such, it is complex. It may require a lot of effort to configure and establish your data models and tagging.

Pricing

Pricing is available by quote and is aimed at enterprise customers.

CloudHealth, from VMware, is another heavyweight in the enterprise cloud management space. Like Cloudability, it's a mature platform designed for large, complex organizations. Its particular strength lies in managing hybrid (on-prem + public cloud) environments and enforcing governance.

If you're a large company with a significant VMware on-prem footprint, CloudHealth is a natural choice. It can give you a single view of your on-prem vSphere costs right alongside your AWS, Azure, and GCP spend.

It's powerful on policy. You can create perspectives (custom business-level views) and then set policies for cost, security, or compliance based on them.

Best features

  • Hybrid Cloud Leader: One of the best tools for managing and reporting on both public cloud and on-prem VMware environments in one place.
  • Strong Policy & Governance: Allows you to create robust, automated policies to govern your multi-cloud environment.
  • Customizable Perspectives: Let's you group and view assets based on business logic (like department or product) rather than just cloud provider accounts.
  • Security & Compliance: Integrates security and compliance reporting with cost management.

Current limitations

Enterprise-Scale & Price: This is a big, complex tool for big, complex companies. It can be expensive and overkill for smaller, cloud-native startups.

Less Focus on Automation: Like Cloudability, it's more of a reporting, analysis, and policy platform than a hands-on, automated optimization engine.

Pricing

Pricing is available by quote from VMware.

Customer ratings and reviews

Not Available, you can check their customer testimonials on their website.

11. Flexera

Flexera Dashboard

Best for: Holistic IT asset management and cloud optimization.

12. Densify

Densify Dashboard

Best for: Advanced, predictive VM rightsizing analysis.

Densify is a highly specialized tool that is obsessed with rightsizing. It uses machine-learning-based predictive analytics to provide highly granular recommendations for your virtual machines and containers.

While other tools might say this VM is oversized, Densify's engine will tell you, based on its 60-day workload pattern, this VM should be an m5.large, which will save you $42.50/month and will still have a 25% performance buffer for your month-end peak. It's that specific. It's great for teams that are scared of rightsizing because they're afraid of breaking things.

Best features

  • Advanced Predictive Analytics: Its core strength. It analyzes workload patterns to give precise, safe rightsizing recommendations.
  • Container Optimization: Can also analyze container workloads to recommend the right CPU/memory requests and limits.
  • Reduces Analysis Paralysis: By providing such high-confidence, data-backed recommendations, it makes it easier for teams actually to approve optimizations.

Best for: Free, native cost reporting for AWS environments.

You can't have a list of cost tools without mentioning the ones built by the cloud providers themselves. AWS Cost Explorer is the free, built-in tool for understanding your AWS bill.

It's a great starting point. It allows you to visualize and analyze your spending over time, filter by things like service (EC2, S3), region, or tags, and get a fundamental forecast.

Best features

  • It's Free: It's included with your AWS account.
  • Source of Truth: This is the data all other tools are based on.
  • Budget Alerts: You can set simple budgets that alert you when you're forecasted to exceed your spend.

Current limitations

AWS-Only: Obviously, you can also only use it for AWS. But even then you can’t fully optimize your savings, to find out how you can reduce your AWS bill upto 30% you need better strategy.

Reactive, Not Proactive: It tells you what you spent, but it does little to prevent you from spending it.

Weak Recommendations: Its rightsizing and recommendations are notoriously conservative.

Pricing

Free.

18. Azure Cost Management

Azure Cost Management Dashboard

Best for: Free, native cost reporting for Azure environments.

Like AWS Cost Explorer, Azure Cost Management is Microsoft's free, built-in tool. It's integrated directly into the Azure portal and provides a similar set of features.

You can analyze your costs, create budgets and alerts, and get recommendations for optimizing your resources. It's a solid, fundamental tool for anyone running workloads on Azure.

Best features

  • It's Free: Included with your Azure subscription.
  • Good Integration: Tightly integrated with the entire Azure ecosystem.
  • Budget Alerts: Easy to set up budgets and get alerts when you're approaching your limits.

Current limitations

Azure-Only: No multi-cloud view (though it has a limited AWS connector).

Complex UI: The Azure portal can be overwhelming, and finding the exact report you need can be a challenge.

Pricing

Free.

19. Google Cloud Cost Management

GCP Cost management Dashboard

Best for: Free, native cost reporting for GCP environments.

Rounding out the big three native tools is Google's Cloud Cost Management. This is a suite of tools built into the GCP console that helps you report on, understand, and control your costs.

GCP's billing is arguably the most customer-friendly of the big three (with per-second billing and automatic sustained use discounts), and its cost tools reflect that. The reports are generally clean and easy to understand.

Best features

It's Free: Part of the GCP console.

Clean & Simple: The interface is generally clean and easier to navigate than its competitors.

Quotas: GCP's concept of quotas is a powerful (if blunt) cost-control tool.

Current limitations

GCP-Only: Only for your Google Cloud spend.

Lacks Depth: While simple, it lacks the Advanced, business-focused reporting of a FinOps tool.

Pricing

Free.

Optimize Your Workflow with the Right Tool

Scaling cloud resources is easy. That's the problem. It's so easy that many teams lose control over their spending. A missed bug, a test environment left running, or a simple architecture oversight can quickly snowball into a massive, shocking bill at the end of the month.

That's why you need a cloud cost monitoring and optimization toolkit. You need a platform that provides detailed visibility, exhaustive reporting, and, ideally,automated optimization capable of handling the fast-changing requirements of modern, cloud-native applications.

While native tools are a great place to start, they'll only get you so far. The real, game-changing savings come from specialized tools that move beyond simple reporting and into a world of proactive, intelligent automation.

And in that new world, autonomous platforms like Costimizer are leading the charge. With its Agentic AI, it's one of the only platforms that doesn't just add to your to-do list with more recommendations. It does the work for you, 24/7.

It’s time to unlock the best FinOps platform for you. Bring all your cloud costs and resources into one place and finally get control of your bill.

Frequently Aksed Questions

Why can't I just use the free tools from AWS, Azure, or GCP?

You absolutely should start with them. They are the source of truth for your bill. But they are limited. They are reactive (tell you what you spent last month), can't show you the real cost of a single feature or customer, and frankly, they are designed to be complicated, to get the most money out of you. Third-party tools are for when your cloud bill becomes too large and complex for a simple report.

What's the first thing I should do to control my costs?

Tagging. Implement a mandatory and consistent tagging strategy (e.g., team, project, environment). Without tags, all your costs are a mystery. You can't optimize what you can't measure, and you can't measure what you can't allocate.

What's the difference between cost optimization and cost reporting?

Reporting tools are excellent for FinOps and finance. They tell you who spent what. Optimization tools (like Costimizer) are suitable for enterprises. They do something to lower the bill, like automatically rightsizing a VM or shutting down an idle resource.

What is rightsizing, and why is it so hard?

Rightsizing is changing a resource to a smaller, cheaper size that still meets its performance needs. It's hard because engineers are terrified of under-provisioning, making a VM too small and causing the application to crash.

My most significant cost is Kubernetes. Where do I even start?

You need a K8s-specific tool. Start with an open-source tool like Kubecost to see your costs. It will show you which namespace, deployment, or pod is costing you money. Once you know what is expensive, you can use an automation tool like Cast AI to fix it by rightsizing, bin-packing, and using Spot Instances.

What's the most common source of cloud waste?

Idle, non-production resources. These are the dev, staging, test, and qa environments that engineers spun up for a project and forgot to turn off. A tool with an auto-stop feature can pay for itself in a single weekend by just shutting these down.

How do I get my engineers to actually care about cloud costs?

You can't. Not really. But you can make the cost visible to them in their workflow. Costimizer (in the pull request) or Harness (in the CI/CD pipeline) show engineers the cost before they even merge their code. When they see that your change will add $5,000/month to the bill, they suddenly start to care.

What if the automation goes wrong and charges me more?

This is a valid fear. The best automation tools are not black boxes. They are performance-aware and will not make a change if it risks an outage. The very best (like Costimizer) use AI to understand the intent and have safeguards, starting with recommendations first, then moving to full automation once you build trust.

I have a hybrid cloud (on-prem + public). What's the best tool for that?

Your choices narrow, but they are powerful. Costimizer is an enterprise-grade platform that is built for this. It is designed to give you a single pane of glass over both your data centre and your public cloud spend.

What tools provide expert advice on optimizing cloud investments while integrating with development tools?

Costimizer helps you optimize cloud investments by giving a unified, AI-powered platform to monitor spend across clouds, detect cost anomalies, and provide actionable savings recommendations, while integrating with dev tools like Slack, Jira, GitHub/GitLab so cost-impact alerts and recommendations reach your engineering workflows directly.
