Common Problems in Cloud Cost Auditing with Compliance

Balancing cloud costs with compliance is a persistent challenge for UK organisations. A staggering 30% of cloud spending is wasted because of limited visibility and poor cost control [4]. When you add regulatory demands into the mix, the situation becomes even more complex. Let’s dive into the specific hurdles around multi-cloud environments, visibility issues, and the ever-changing regulatory landscape.

Multi-Cloud Environment Complexity

Using multiple cloud providers may offer flexibility, but it also introduces a host of challenges. With 84% of companies relying on multi-cloud setups [9], managing costs and ensuring compliance becomes increasingly tricky. Each provider comes with its own security protocols and compliance requirements, which can clash or create gaps. Data sovereignty adds another layer of difficulty, especially with regulations like the CLOUD Act influencing how UK organisations manage data stored across borders [3]. For CIOs, unexpected cost spikes and the risk of vendor lock-in are major headaches [2]. These complexities often lead to fragmented oversight, making it harder to maintain control - a problem closely tied to visibility and accountability.

Poor Visibility and Accountability

When organisations lack transparency, they open the door to misconfigurations and unauthorised access, putting sensitive data at risk [5]. This lack of clear oversight can lead to teams making uninformed decisions, unaware of the financial or compliance consequences. The result? Operational inefficiencies, wasted resources chasing down unexplained expenses, and a reluctance to innovate due to fears of overspending [6]. Without proper accountability, these issues compound, creating a cycle of inefficiency.

Changing Regulatory Requirements

Keeping up with regulatory changes is a constant struggle, especially as technology evolves faster than the rules governing it [7]. While 94% of businesses plan to boost their cloud spending by over 45% [9], many find it challenging to align this growth with compliance. The lack of consistency in regulations across jurisdictions only adds to the complexity. For multinational organisations, managing differing rules becomes especially daunting, particularly as emerging technologies like AI in areas such as underwriting and pricing attract heightened regulatory attention. These shifts often demand costly adjustments to cloud architectures, further straining budgets [8].

Best Practices for Cloud Cost Auditing with Compliance

Managing cloud costs while staying compliant can feel like a juggling act, especially with over 90% of organisations relying on multiple cloud providers [10]. To keep things under control, a mix of clear goals, structured processes, and automation is key.

Set Clear Audit Goals

Before diving into an audit, define what you're aiming to achieve. This means setting goals that align with both your budgetary targets and compliance requirements, such as GDPR, SOC 2, or PCI-DSS. Make sure your audit covers all the cloud providers you use - whether it's AWS, Microsoft Azure, or Google Cloud - each of which comes with its own set of compliance certifications and processes [10].

Start by identifying the regulations that apply to your business, mapping them to your cloud resources, and setting measurable targets. For example, you might aim to flag resources costing over £1,000 a month without proper justification or ensure all production resources meet specific data classification standards. These goals not only keep your team focused but also provide tangible metrics to gauge success.

Each provider’s native tools require separate configurations, and data sovereignty concerns can make things trickier. Having these goals in place sets the stage for the next step: consistent tagging.

Use Consistent Tagging and Categories

Once your audit objectives are clear, consistent tagging becomes the backbone of your cost tracking and compliance efforts. Without it, keeping tabs on expenses and ensuring governance is like trying to navigate without a map.

Tags are a crucial part of organising your Azure resources into a taxonomy. When following best practices for tag management, tags can be the basis for applying your business policies with Azure Policy or tracking costs with Cost Management. - Microsoft Learn [12]

Develop a tagging strategy that outlines how tags should be used, formatted, and managed. This includes assigning responsibilities and defining procedures for maintaining tag consistency [11]. Tags make it quicker to identify affected systems, understand their roles, and assess the potential impact during incidents [11].

Take the example of Contoso Corp, a UK-based small business. They used automated tagging to cut their Azure expenses by 15% in just three months [12]. By tagging resources with cost centres, environments, and project codes, they gained clearer visibility into their spending.

Keep your tagging system straightforward. Use consistent formats like camelCase and avoid free-form text to prevent errors. Azure, for instance, supports up to 50 tags per resource [12], so start with the essentials and expand as needed. Assigning tag owners ensures everyone understands the purpose of each tag, and regular audits keep them relevant and accurate [11][12].

Use Automation for Continuous Monitoring

Relying on manual checks for compliance is not just slow - it’s also prone to mistakes. Automating these processes can save significant time (up to five working weeks per year) while offering continuous oversight to catch issues early [15].

Governance-as-Code (GaC) is a game-changer for automating compliance in cloud cost management. By defining rules for cost allocation, resource tagging, budget limits, and access controls as code, you can enforce policies consistently and address problems swiftly [13].

For instance, a mid-sized SaaS company implemented Rego-based policies to enforce mandatory cost centre tags, restrict instance sizes, and limit certain services in non-production environments. Using tools like Open Policy Agent (OPA) integrated with GitHub Actions, they set up daily compliance scans displayed on Grafana dashboards. The result? A 20% reduction in monthly cloud costs, better accountability, and improved audit readiness [13].

Start small by focusing on critical policies and gradually expand. Choose policies that can be tested and enforced in real-world scenarios [13]. Auto-remediation, like tagging missing resources or shutting down non-compliant instances, can further ease the workload while ensuring rules are followed.

Integrate automation into your CI/CD pipelines to evaluate compliance at every deployment stage [13]. Tools like Open Policy Agent, Terraform Sentinel, AWS Service Control Policies, and Azure Policy are excellent for enforcing these rules across your environment.

The stakes are high: with the global average cost of a data breach hitting $4.93 million [14] and UK businesses losing around £44 billion to cyber-attacks over five years [14], automated monitoring isn’t just a convenience - it’s a critical safeguard against financial and regulatory risks.

Tools and Technologies for Cloud Cost Auditing and Compliance

For UK businesses tackling the dual challenges of managing cloud costs and meeting regulatory demands, having the right tools is non-negotiable. This section highlights the options available, from native cloud provider tools to third-party platforms, and how they cater to the unique needs of organisations.

Cloud Provider Native Tools

Native tools provided by cloud platforms themselves are often the first stop for businesses looking to monitor and manage costs. Here’s how the major players stack up:

AWS Cost Explorer is one of the most widely used native tools. It provides detailed cost analysis, including filtering options, budget forecasting, and the ability to export data. These features are invaluable for quarterly financial reporting, making it a popular choice among UK businesses [17].

Azure Cost Management, integrated with Microsoft's ecosystem, offers free tracking of Azure-related expenses and budget alerts. Its standout feature is departmental cost allocation, which is particularly useful for organisations using chargeback models. Automated billing based on usage further simplifies financial controls for businesses.

Google Cloud Cost Management provides advanced analytics and spend tracking. Its ability to break down costs by project, service, and region is especially helpful for UK companies managing data sovereignty across different locations. Like its counterparts, it’s free with GCP services.

While these tools are effective within their respective ecosystems, they often struggle in multi-cloud setups, pushing businesses to explore third-party solutions.

Third-Party Platforms with Compliance Features

For businesses operating in multi-cloud environments or grappling with complex compliance needs, third-party platforms offer more robust solutions. These tools often combine cost management with compliance oversight, making them ideal for UK organisations navigating regulations like GDPR.

CloudCheckr is known for its granular reporting and security vulnerability tracking. Users appreciate its intuitive interface and detailed cost visibility [17]. However, it does have limitations, particularly when it comes to integration speed with platforms like Azure and Google Cloud. It holds a 7.6 rating, with 66% of users willing to recommend it [17].

Akitra goes a step further with AI-enabled compliance automation, making it a strong choice for businesses prioritising GDPR compliance alongside cost management [18]. Its ability to seamlessly operate across multiple cloud environments is a big draw for UK organisations.

CloudZero offers a comprehensive view by consolidating cost data from providers like AWS, Azure, GCP, and Kubernetes, as well as SaaS platforms such as Snowflake and Databricks [19]. This unified approach allows businesses to track both cloud infrastructure and software spending in one place, a feature that simplifies financial oversight.

The Bottom Line

The choice between native tools and third-party platforms often depends on the complexity of your cloud environment and your compliance needs. For smaller setups or those just beginning their cloud cost auditing journey, native tools provide a solid starting point. However, as multi-cloud adoption increases and regulatory requirements grow more demanding, third-party platforms offer the advanced features and cross-cloud visibility that modern businesses need.

It’s worth noting that compliance software can significantly reduce risks. According to research, 68% of organisations report that such tools have helped them mitigate non-compliance risks, while 59% have experienced improved compliance transparency [16]. As former U.S. Deputy Attorney General Paul McNulty famously said:

If you find compliance costly, just try non-compliance! [16]

For UK organisations, balancing cost efficiency with regulatory adherence is no easy feat. The right tools - whether native or third-party - can make all the difference.

How Expert Consulting Helps with Cloud Cost Auditing

While tools provide a solid starting point, managing costs and ensuring compliance in today’s multi-cloud setups often requires a level of expertise that goes beyond what most internal teams can offer. This is where expert consulting services step in, offering the strategic insights and technical skills to bridge the gap.

With 90% of businesses already using cloud services and 51% of IT spending predicted to shift to cloud-based solutions by 2025 [21], the cloud has become a cornerstone of modern IT operations. However, many organisations face a dual challenge: controlling costs while staying compliant with complex regulations. Expert consultants address these issues by creating tailored strategies that combine cost control with regulatory adherence. Their role often extends to building customised audit frameworks and ensuring ongoing optimisation.

Custom Audit Frameworks

One of the standout benefits of working with expert consultants is their ability to craft custom audit frameworks tailored to your specific cloud setup. Unlike generic solutions, these frameworks are designed to handle the unique challenges of public, private, and hybrid cloud environments.

Take Protiviti, for instance. They developed a tailored roadmap for a leading bank, aligning its cloud strategy with business goals, modernising outdated systems, and improving service reliability [20]. This kind of bespoke approach not only addresses industry-specific compliance needs, such as GDPR for UK organisations, but also uncovers opportunities to cut unnecessary costs.

For UK businesses, navigating regulations like GDPR and NIS is no small task. Expert consultants ensure that these requirements are met without compromising on cost efficiency. And their work doesn’t stop there - maintaining compliance over time is just as important as meeting it initially.

Continuous Compliance and Cost Support

Cloud environments are constantly evolving, with new services and changing regulations keeping teams on their toes. For many organisations, especially smaller ones, staying on top of these changes can be overwhelming. This is where the ongoing support of expert consultants becomes invaluable.

Consider this: 41% of organisations experience project delays due to compliance issues [23]. These delays can be costly, but expert consultants help prevent them by providing continuous monitoring and fast responses to new compliance challenges. Such proactive management can lead to significant savings - up to 30% on current cloud consumption costs [23].

Consultants like those at Hokstad Consulting offer a range of ongoing services, including cloud security audits, performance reviews, and compliance documentation. They also help businesses navigate the shared responsibility model of cloud computing. While cloud providers handle infrastructure security, the responsibility for securing operations falls on the organisation. Expert consultants step in with regular security assessments, compliance checks, and cost reviews, ensuring nothing slips through the cracks. This is particularly critical as 40% of IT decision-makers acknowledge the need for external cloud security expertise [21].

Beyond the technical side, expert consulting provides a broader value proposition. As Arianna Campbell from Boomer Consulting puts it:

Technology and process can be the difference between a good firm and a great firm. Do not let the sunk costs of your existing software deter you from making changes that will benefit your firm in the long term. Investing in tools and applications that will allow your team to achieve maximum productivity will lead to greater productivity and enable your firm to spend time building quality relationships with your clients. [22]

By taking on the heavy lifting of cost auditing and compliance, consultants free up internal teams to focus on their core business activities. For UK organisations grappling with the complexities of cloud governance, this external expertise is often the key to balancing cost efficiency with regulatory demands.

Hokstad Consulting also offers flexible engagement models, such as retainer-based support or savings-based agreements, ensuring their incentives align with delivering measurable outcomes.

Conclusion: Balancing Cost Efficiency with Compliance

Striking the right balance between cost control and compliance in cloud environments is no small feat, but it’s entirely achievable. By addressing the challenges of multi-cloud setups, adopting smart practices, and seeking expert guidance, businesses can manage their spending effectively while ensuring they meet regulatory demands.

Success in this area hinges on three main actions. First, adopting practices like consistent tagging, automated monitoring, and regular audits establishes a strong foundation. These steps not only streamline operations but also help identify inefficiencies early. Second, using the right tools - whether built into cloud platforms or offered by third-party providers - gives businesses the visibility they need to manage costs while staying compliant with regulations.

Expert input adds another layer of precision. Firms such as Hokstad Consulting specialise in tailoring cloud cost auditing strategies that align with both financial goals and compliance requirements. According to McKinsey Digital, optimising cloud costs can reduce programme expenses by 15–25% [24], all while maintaining adherence to regulations. This is especially relevant considering that 67% of global organisations report higher-than-expected cloud expenses [25].

Cloud cost optimisation combines strategies, techniques, best practices and tools to help reduce cloud costs, find the most cost‐effective way to run your applications in the cloud environment, and maximise business value.
