Optimize Cloud Costs with Datadog Cloud Cost Management

Cloud Cost Tools and Their Tracking Features

Here are seven tools that UK businesses can use to manage and monitor their cloud spending effectively. These include Cloudability by Apptio, Datadog, Harness, Kubecost, CloudZero, Finout, and Nutanix. Each offers different levels of detail, from resource-level tracking across multiple clouds to Kubernetes-specific insights. The best tool for your needs depends on your infrastructure, whether you're running containerised workloads, hybrid setups, or need to align costs with business metrics.

What these platforms have in common is their ability to allocate costs accurately to teams, products, or cost centres, detect anomalies and waste before they lead to unexpected bills, and provide near real-time data for finance and engineering teams to act within the same billing cycle. They often support tagging strategies and integrate with CI/CD pipelines and monitoring systems. For companies managing AWS, Azure, GCP, or private cloud setups, having multi-cloud support and unified dashboards is vital.

However, success with these tools hinges on consistent tagging and detailed billing exports. Without clean metadata, even the most advanced tools can't allocate costs correctly. Many UK businesses start by testing granular tracking in one department, refining their tagging approach, and then scaling the process across the organisation. Consultancies like Hokstad Consulting can assist with designing tagging strategies, integrating tools with existing DevOps workflows, and training teams in FinOps practices tailored to mixed public/private cloud environments.

Below is a closer look at the tracking features of each tool.

Cloudability by Apptio

Cloudability provides resource-level cost visibility for AWS, Azure, and GCP by using advanced tagging to map spending to specific business units, applications, teams, accounts, or environments [4][2]. It combines billing, usage, and monitoring data to support budgeting, forecasting, rightsizing recommendations, and anomaly detection [4]. For instance, a UK retailer could allocate £250,000 in monthly multi-cloud expenses to product lines using tag-based mappings, while a tech scale-up might use Cloudability's reports to evaluate costs per customer or transaction. The platform also offers container cost tracking, allocating Kubernetes expenses back to squads or namespaces. Integration with tools like PagerDuty and Datadog [4] ensures unified governance across diverse cloud environments.

Datadog

Datadog excels at combining infrastructure and application metrics with cloud cost data, making it possible to view costs by service, tag, team, environment, or deployment [7][4]. Its real-time dashboards and alerts help teams quickly identify cost spikes, such as those caused by a misconfigured auto-scaling group or a chatty microservice, often within minutes instead of waiting for monthly invoices. For example, a UK SaaS company might track costs per host or request in real time and set alerts to flag when a service's cost per 1,000 requests exceeds a set threshold. While cost features are secondary to Datadog's core observability tools [1][6], the ease of having cost insights alongside logs, metrics, and traces makes it a popular choice.

Harness

Harness offers detailed workload-level cost tracking across clusters, namespaces, and services, along with utilisation breakdowns that separate data into used, idle, and unallocated resources [8]. By linking costs to deployments and pipelines, teams can assess the financial impact of new releases and benefit from recommendations for rightsizing, scheduling, and Cloud Autostopping, which shuts down non-production workloads outside business hours. Harness claims savings of up to 70% through these insights and automation [3]. For instance, a UK fintech firm could improve Kubernetes cluster utilisation from 45% to 70%, saving tens of thousands of pounds annually, or implement policies to prevent overspending.

Kubecost

Kubecost focuses on Kubernetes environments, providing cost allocation at the namespace, deployment, service, and pod levels, with support for multiple clusters and clouds in a single view [8][2]. It maps infrastructure expenses - covering nodes, storage, and networking - back to Kubernetes concepts, enabling precise showback and chargeback for teams or products [8]. Its open-source foundation is particularly appealing to engineering-driven organisations looking for in-cluster cost visibility without vendor lock-in [2]. For example, a UK media company could allocate £60,000 in monthly EKS and GKE expenses across feature teams using namespace labels and identify a noisy neighbour deployment causing disproportionate costs. Historical cost trends also aid in capacity planning and budgeting, though Kubecost's focus is primarily on containerised workloads.

CloudZero

CloudZero specialises in creating views of unit economics, such as costs per customer, feature, environment, or transaction, by combining billing data, telemetry, and detailed tagging [4]. Its anomaly detection and cost event attribution features go beyond simply flagging increased spending - they identify which team, feature, or deployment caused the spike. For instance, a UK subscription business might monitor cost per customer per month to ensure this metric stays within target ranges, helping justify price adjustments to investors. Finance teams can also use its dashboards to guide budgeting and forecasting. This focus on aligning costs with business metrics makes it especially useful for SaaS companies and product-led organisations.

Finout

Finout consolidates billing data from various sources - AWS, Azure, GCP, Kubernetes, SaaS, and data platforms - into a single cost hub. It then allocates expenses to cost centres, teams, or business units using tags, labels, and virtual tags or hierarchies [6][5]. Shared costs, like those from an EKS cluster or data warehouse, can also be split across product teams, and the platform provides fine-grained, usage-based cost metrics [6]. For example, a UK e-commerce company could combine cloud, CDN, and payment processing invoices to calculate the total cost per order or split platform expenses between UK and EU regions. By unifying diverse billing data, Finout reduces the manual effort of reconciling invoices and provides a centralised view for cost allocation.

Nutanix

Nutanix (formerly Beam) is designed for hybrid and multi-cloud cost management, offering detailed metering of compute, storage, and network resources across public and private clouds [4]. Its features include cost allocation, chargeback, budget tracking, rightsizing, discount management, and anomaly alerts [4]. For example, a UK public sector organisation might allocate private cloud usage to specific departments, while a large enterprise could compare the cost per VM between on-premises Nutanix clusters and AWS to guide migration decisions. Nutanix's anomaly alerts can also catch runaway test environments before they inflate costs. For businesses with hybrid infrastructure, Nutanix provides a comprehensive solution for monitoring and optimising costs across both on-premises and cloud environments.

Granular Tracking Capabilities Compared

When it comes to tackling inefficiencies that drive up cloud costs, each tool offers tailored granular tracking features designed to meet specific business requirements. Here's how they stack up:

Cloudability zeroes in on account, service, tag, and business unit mapping. This setup enables precise cost allocation through showback and chargeback, aligning with FinOps best practices [4]. Datadog, on the other hand, links costs to hosts, containers, services, and tags. For teams already using Datadog for observability, this integration makes it easier to view spending alongside performance metrics [4]. Harness takes a different approach by focusing on applications, services, environments, and Kubernetes workloads, categorising resources as used, idle, or unallocated [8]. Meanwhile, Kubecost dives deep into Kubernetes environments, breaking down costs by cluster, namespace, deployment, service, pod, and label - ideal for container-heavy setups [8].

CloudZero uses tags, account data, and Kubernetes metadata to categorise costs by product, feature, customer, or environment [4]. Finout employs hierarchies and virtual tags, allowing teams to slice costs by team, feature, or customer - even without perfect native tagging [6]. Finally, Nutanix supports cost allocation by project, business unit, and application across public, private, and hybrid environments [4].

Multi-cloud Integration and Real-time Visibility

Beyond granular tracking, these tools differ in their ability to integrate with multi-cloud environments and provide real-time insights. Cloudability, CloudZero, Finout, and Nutanix all pull billing data from AWS, Azure, and GCP, with Finout and CloudZero also integrating SaaS costs to offer a unified financial overview [4][6]. Datadog supports AWS, Azure, GCP, and other providers, correlating usage and billing metrics across platforms [4]. Harness aggregates spend data for applications spanning AWS, Azure, and GCP [8]. Kubecost, designed for Kubernetes, runs in-cluster and supports multi-cloud or on-premises environments, presenting costs across clusters in a unified view [8].

Real-time visibility is another key differentiator. Tools like Datadog and Kubecost offer near real-time tracking, while Cloudability, CloudZero, and Finout update data several times daily, enabling same-day FinOps decisions [4][6][8]. Harness links cost data to deployments, offering near real-time insights into the financial impact of new releases [8]. Nutanix, meanwhile, provides ongoing cost metering, which is particularly useful for governance and capacity planning [4].
