5 simple ways to implement cloud cost optimization

Start with a Cloud Cost Audit to Find Quick Savings

Take a closer look at your cloud expenses to identify inefficiencies that could be consuming 20–30% of your budget [5]. A thorough audit can reveal patterns and opportunities for immediate savings, with many organisations cutting costs by 20–40% after conducting one [6]. Begin by identifying idle resources and setting spending benchmarks to guide your cost-saving efforts.

Find Unused Resources and Zombie Assets

Unused resources like idle virtual machines, unattached storage, and outdated services can quietly drain 40–60% of your cloud capacity without providing any real benefit [7].

Start by evaluating compute instances for low CPU usage over the past month. For example, an e-commerce company found several production instances running at just 15% CPU utilisation - ideal candidates for downsizing without impacting performance [5]. Tools like AWS Cost Explorer or Azure Cost Management can help you quickly identify these underused assets.

Storage inefficiencies are another common culprit. One organisation discovered 40TB of untouched log files stored in standard S3. By moving them to Glacier Deep Archive, they slashed costs by 95% [5]. Look for similar opportunities, such as unattached EBS volumes or Azure disks, snapshots that exceed retention policies, and old development databases or backups stored in high-cost tiers.

Don’t overlook orphaned resources, like unused load balancers, idle IP addresses, or abandoned development environments. For example, Brazilian furniture retailer Tok&Stok implemented automated monitoring to adjust compute capacity based on demand, significantly reducing costs from idle servers [8].

Automation can be a game-changer here. A major retailer used anomaly detection to identify a misconfigured Lambda function that was racking up roughly £480 per day in unnecessary expenses. Thanks to automation, they caught this issue within hours instead of weeks [5].

Review Spending Patterns and Create Baselines

Once you’ve dealt with idle and unused resources, shift your focus to reviewing spending patterns and establishing baselines for better cost management.

Analyse a 90-day spending history to uncover trends, seasonal spikes, and unusual cost increases that may signal underlying issues [5]. This data helps you map cloud resources to specific business units, projects, and environments. Consistent tagging - using labels like CostCenter, Project, and Environment - is essential for tracking expenses accurately [5].

Set cost baselines for each major workload or department. For instance, if your development environment costs £2,000 per month, use that as a benchmark to measure the impact of scheduling and rightsizing efforts over the next 100 days.

Don’t forget to review data transfer costs, which can sometimes be unexpectedly high. One software company discovered they were spending more on cross-region data transfers than on compute resources [5]. Analysing network traffic patterns and consolidating workloads into fewer regions can help mitigate such costs.

Finally, implement weekly cost reviews to catch issues early. Automated reports can highlight resources missing critical cost allocation tags, which often indicate new, untracked spending that could spiral out of control. Regular monitoring ensures you stay on top of your cloud expenses and avoid unpleasant surprises.

Apply Quick Resource Optimisation Techniques

If you're looking for immediate savings without diving into complex development work, these simple adjustments can help align your resources with actual usage and eliminate waste. Building on your audit findings, these methods can lead to noticeable cost reductions right away.

Rightsize Overprovisioned Compute Resources

Matching your compute resources to actual workload demands - known as rightsizing - can save you a substantial amount of money. It eliminates the expense of paying for resources that are either underutilised or no longer needed [9][3].

In fact, rightsizing can slash costs by as much as 70%, with typical savings ranging from 40–60% in well-managed setups [9]. Studies show that companies often overprovision their applications by up to 30%, and nearly 40% of instances are at least one size larger than required [11].

To get started, monitor key metrics like CPU, memory, network, and disk usage over the past 30 days [10]. Look for instances consistently running below 20% CPU utilisation or with excessive memory allocation [9]. Downsizing even one instance by a single size can cut costs by 50%, while reducing it by two sizes can save up to 75% [11].

Tools like AWS Compute Optimizer and Azure Advisor can offer specific recommendations tailored to your workloads, making it easier to align your resources with your audit findings [3].

“Rightsizing gives you a clear view of the type of cloud resources you should use in your infrastructure. Rather than blindly adhering to vendors, you can choose the right type of workloads and volumes that meet your business needs,” says Josh Paine from Cass Information Systems, Inc. [9]

Focus on evaluating how your volumes, virtual machines, and instances perform against your benchmarks. Based on this analysis, upgrade, downgrade, or terminate resources as needed. This straightforward approach can significantly reduce your cloud expenditure.

Once your compute resources are in check, you can turn your attention to adjusting usage patterns in non-critical environments.

Schedule Shutdowns for Non-Production Environments

Non-production environments like development, testing, and staging don't need to run around the clock. Yet, many companies waste up to 35% of their cloud budgets on idle resources. By implementing smart scheduling, you could cut these costs by as much as 40% [12].

Start by auditing when these environments are actually in use. Most development teams work standard business hours, making evenings and weekends ideal times for automated shutdowns. This simple step can reduce costs by 30–50% [12].

Use tools like Azure Automation or Terraform to set up custom schedules that align with your team's working hours, such as 8:00–18:00 GMT. Add smart tagging to track and manage shutdowns, and ensure your team is aware of these policies to avoid disruptions [13].

For example, a fintech company running multiple test environments on Azure saved tens of thousands of pounds annually by scheduling shutdowns during off-hours, cutting environment costs by 30–50% [12]. Similarly, another customer reduced EC2 costs by over 30% in just one month [13].

Remove Orphaned Storage Assets

Orphaned resources - like unattached storage volumes - can quietly inflate your cloud bill. These often accumulate when virtual machines are deleted but their associated storage remains active [15].

“Each virtual machine disk volume provisioned in your Azure cloud account is adding charges to your monthly bill, regardless of whether the resource is being used or not. Removing unattached/orphaned data disk volumes can help you avoid unexpected charges on your Azure bill,” explains Trend Micro [14]

Regularly audit your environment for unused EBS volumes, Azure disks without VMs, and storage accounts that haven’t been accessed in months. Tools like the Azure Orphan Resources Workbook can simplify this process [15][16].

Before deleting any storage, create snapshots as a backup to safeguard against accidental data loss. Snapshots are a cost-effective way to retain important data while eliminating unnecessary storage costs [14].

The savings here can add up quickly. In one Microsoft case study, a customer saved approximately £5,600 per month by removing unused disks and an additional £80 per month by deleting unused public IPs [15]. Automation tools like Azure Automation can further streamline the process by automatically deleting orphaned resources based on predefined criteria [15].

“When businesses move from on-premises infrastructure to the cloud, they need to undergo a significant mindset shift… This requires businesses to adopt a more dynamic approach to cost management, continuously monitoring and optimising their cloud resources to avoid unnecessary expenses,” says Chris Henry, Head of Azure CoE [15]

Use Cost Monitoring Tools and Automation

Once you've optimised your resources, the next step is to put monitoring tools in place. These tools keep an eye on usage, costs, and performance around the clock, alerting you to any spikes or underutilised assets. Cloud cost monitoring tools give you real-time insights into how your cloud services are being used, helping you identify cost increases, unused resources, and unusual patterns. With instant alerts, you can make informed decisions to cut waste and improve efficiency [18].

The importance of effective monitoring can't be ignored. According to Virtana, 94% of IT teams have noticed a rise in their cloud storage costs, and 54% report that these costs are climbing faster than their overall cloud expenses [17]. This highlights why having a strong monitoring system is crucial - it ensures you maintain control over your cloud environment.

Use Heat Maps to Study Usage Patterns

Heat maps are a handy way to visualise usage data, showing when your resources are most and least active. These visuals make it simple to spot times - like weekends or holidays - when scaling down resources can save costs, without needing to dig into complicated analytics. For instance, you might find that your development environments are barely used between 18:00 GMT on Friday and 08:00 GMT on Monday, making them ideal candidates for automated shutdowns.

Modern tools equipped with AI can provide even deeper insights, revealing usage trends and predicting costs. They can recommend specific scaling or scheduling adjustments [19][17]. The trick is to zero in on resources with consistent low activity during certain times - these are prime targets for automation. Heat maps can also help you track seasonal usage changes, giving you the foresight to manage cost fluctuations throughout the year.

Set Up Multi-Cloud Cost Monitoring

If you're using multiple cloud providers, managing costs can get tricky. A unified platform that consolidates all cost data into a single dashboard can make a big difference. This approach simplifies tracking and ensures you don’t miss optimisation opportunities across your cloud environments.

When choosing a multi-cloud monitoring tool, look for features like:

• Cost Visibility: Clear breakdowns by service, team, or project [2].
• Real-Time Monitoring: Alerts for sudden spending spikes [2].
• Multi-Provider Integration: Support for platforms like AWS, Azure, and Google Cloud [2].
• Budgeting & Forecasting: Set pound-based thresholds and predict spending trends [2].
• Cost Allocation & Tagging: Assign costs to specific business units or projects [2].

For tighter budget control, configure alerts in pounds sterling. For example, you could set alerts to trigger if monthly spending exceeds £5,000 or if costs rise by more than 20% week-over-week.

Martin Amps from Stitch Fix highlights the importance of detailed cost tracking:

Best practices are important, but there's no substitution for real measurement and cost optimisation. Datadog Cloud Cost Management helped us attribute spend at a granular level over dozens of accounts to achieve significant savings. [20]

Tim Ewald, CTO at Kevel, also stresses the organisational benefits of proper monitoring:

It's not about tradeoffs between cost and performance: cost is a need, just as important as scalability and security. CCM has empowered engineers in our organisation to understand this and act on cost data in the same way they would on performance, to maintain efficiency as we scale. [20]

To streamline cost tracking, set up automated tagging policies. This ensures all cloud resources follow consistent naming and tagging conventions [21]. Such consistency simplifies tracking across teams and projects, making it easier to produce accurate reports for showback or chargeback.

Secure Discounts and Long-Term Savings Commitments

Once you've optimised your resources and set up effective monitoring, the next logical step is to focus on securing discounts that offer long-term savings. Commitment-based discounts can significantly cut costs, building on the immediate savings achieved through optimisation.

These discounts rely on usage forecasts to lock in reduced rates. For instance, reserved instances and savings plans can provide up to 72% savings compared to on-demand pricing [23][24]. However, the trade-off is that more specific commitments, such as one- or three-year terms, often come at the cost of flexibility [22].

Align Discounts with Your Business Needs

Instead of basing your discount purchases solely on current usage, it's crucial to evaluate options that fit your actual workloads and financial objectives. This involves collaboration across teams to accurately predict future usage [22].

Start by thoroughly assessing your organisation's needs. Analyse workloads, usage patterns, and growth forecasts before committing to any long-term plans [25]. Avoid locking into outdated technologies or resources that may not align with your organisation’s roadmap [25].

When considering Savings Plans vs Reserved Instances, here’s how they compare:

Savings Plans are more flexible, allowing you to commit to an hourly spend rather than specific configurations. This makes them better suited for dynamic and evolving workloads. On the other hand, Reserved Instances are ideal for predictable, steady-state environments where capacity reservations are needed [24].

To make the right choice, involve key stakeholders - such as engineering, finance, and management teams - in the decision-making process. A FinOps practitioner can help coordinate efforts and ensure that commitments align with both technical and financial goals [22]. Additionally, check how your cloud provider applies discounts, as their order of operations may influence where within your cloud setup the commitment should be applied [22].

Once you’ve aligned these commitments with your business strategy, the next step is to calculate their financial impact.

Break-Even Points and Financial Impact

Understanding the break-even point (BEP) is essential for evaluating the value of a commitment. The BEP represents the time it takes for the savings from a discount to cover its upfront cost [22]. For example, a one-year commitment typically breaks even in about six months, while a three-year term may take closer to nine months [26].

To calculate the payback period, divide the upfront cost by the monthly savings. For instance, if you invest £10,000 in reserved instances and save £2,000 per month, your break-even point would be five months.

Here are some key factors to consider when calculating commitments:

• Risk tolerance: Assess the potential wastage from under-utilised commitments by multiplying the committed cost per hour by the total hours committed [22]. If the risk feels too high, consider shorter terms, lower coverage percentages, or more flexible options [22].
• Available funding: Evaluate how these commitments affect your working capital and other investment priorities. Align purchases with your organisation’s budget cycles and treasury operations [22].
• Organisational capabilities: Forecast usage conservatively and start with smaller commitments if necessary. Waiting for perfect data can delay potential savings [22].

A real-world example illustrates the power of strategic coverage decisions. In one case, covering 2,838 instances instead of the minimum 1,768 resulted in a 161% increase in coverage. Even with utilisation dropping to 93.8%, the approach boosted the effective savings rate by 28%, translating to an additional £8,600 in monthly savings - or £103,200 annually [23].

This example shows that under-utilisation isn't always a problem. In some cases, accepting slightly lower utilisation can actually maximise your overall savings. These strategies, when integrated into your broader cost control plan, help support a sustainable approach to long-term cost management.

Conclusion: Maintain Long-Term Cloud Cost Control

After tackling the quick wins and resource adjustments previously outlined, keeping cloud costs under control for the long haul is entirely achievable. Cutting cloud expenses by 50% within 100 days is possible with strategies that balance minimal development effort and significant financial impact.

A cornerstone of this process is regular cloud cost audits. Instead of treating audits as a one-off task, make them a quarterly routine. These audits are crucial for identifying weak points and guiding automated solutions. A risk-based approach works best, focusing on the most vulnerable areas and using automation to reduce manual workloads.

Automation tools are indispensable for sustaining these cost savings. Automating tasks like shutting down non-essential development environments outside working hours can yield substantial savings. AI-powered platforms can further enhance this by offering real-time cost-saving recommendations, ensuring resources align with business objectives. This is especially critical considering that up to 30% of cloud spending is wasted on unneeded resources [4].

To keep stakeholders focused, track five key metrics. These should include cost per service, resource utilisation rates, and costs from idle resources. At least 75% of cloud expenses should be correctly allocated to maintain financial clarity [27]. Regularly revisiting your KPIs ensures they stay aligned with both your business goals and the shifting dynamics of cloud usage.

Beyond monitoring, long-term discount commitments provide an additional layer of savings. These commitments need active management to remain effective, requiring regular checks on utilisation rates and adjustments to reflect changes in your infrastructure.

These strategies don’t just save money - they position organisations for a competitive edge. With Gartner projecting global public cloud spending to surpass $720 billion (around £575 billion) by 2025 [1], mastering these cost-control fundamentals is essential. The initial 100-day plan lays the groundwork for immediate savings, while embedding these practices ensures ongoing control as your cloud environment evolves.

Start now: conduct an audit this week, implement automated monitoring within a month, and secure discount commitments by day 60. The combined impact of these efforts will not only meet your short-term goals but also establish a scalable, long-term framework for managing cloud costs effectively.
