The Infra Budget Is Leaking Here’s Where
Cloud budgets often spiral out of control due to unused resources, poor scaling setups, and lack of visibility. Businesses - especially in the UK - are seeing rising costs without added value. Here's where money leaks and how to fix it:
- Oversized/Unused Resources: Large instances or storage volumes left active unnecessarily.
- Abandoned Services: Test environments, backups, or DNS configurations running long after use.
- Poor Scaling: Static or overly aggressive scaling setups waste resources during low traffic.
- Untracked Team Spending: Unsupervised accounts or shadow IT inflate costs.
- No Monitoring: Lack of alerts or approval workflows leads to unnoticed overspending.
Quick Fixes:
- Audit resources regularly to match needs.
- Automate scaling and schedule non-production environments to shut down after hours.
- Remove unused storage, snapshots, and other inactive services.
- Use cost-monitoring tools like AWS Cost Explorer or third-party platforms like CloudHealth.
- Implement FinOps practices for better cost control across teams.
By addressing these issues, you can regain control of your cloud spending while maintaining performance.
Unlocking the Secrets of Cloud Cost Optimization
Where Your Cloud Budget Is Bleeding Money
Cloud costs can spiral out of control if you’re not paying attention to the details. Let’s break down some of the most common areas where expenses quietly pile up and how they can be managed.
Oversized and Unused Resources
One of the biggest culprits behind unnecessary cloud spending is over-allocating resources. Teams often choose larger instances "just to be safe" or ramp up capacity during high-demand periods but fail to scale back down once the demand subsides. For example, launching an oversized instance for a new feature can lead to significant waste when a smaller configuration would have been sufficient.
Another common issue is unattached storage volumes. These might be leftovers from migrations, failed deployments, or short-lived testing environments. Despite being unused, they continue to rack up charges. Similarly, database instances often have more CPU and memory allocated than necessary, meaning you’re paying for capacity that sits idle. On top of that, leaving load balancers or network gateways active when they’re no longer needed adds to the waste.
Abandoned Services Running in the Background
It’s easy to forget about test environments or temporary databases that were set up for a specific purpose and left running long after they’ve served their use. These forgotten services can quietly drain your budget.
Container orchestration systems like Kubernetes can exacerbate the problem. Unused node groups, lingering Docker containers, or services without active tasks can all contribute to background costs. Even managed control planes for containers can generate recurring charges when no worker nodes are active.
Backup and snapshot storage is another sneaky expense. Without proper lifecycle management, automated snapshots can accumulate indefinitely, creating a bloated archive of outdated backups. Additionally, content delivery networks (CDNs) and DNS configurations tied to retired projects or discontinued applications can keep adding to your bill.
Poor Scaling Setup
Static resource allocation is a money pit during periods of low traffic. Cloud platforms offer dynamic scaling options that can adjust resources based on demand, but if these aren’t set up correctly, you’ll likely end up overspending.
Manual scaling is another issue - it’s slow, inefficient, and often results in oversized resources being left active longer than needed. Even automated scaling can backfire if the settings are too aggressive or the minimum thresholds are set too high. For non-production environments, like development or testing, running resources 24/7 is usually unnecessary. Scheduling these resources to operate only during working hours can lead to significant savings.
Untracked Team Spending
When developer accounts go unsupervised, unexpected charges can pop up. Developers might spin up instances for personal projects or experiments and forget to shut them down, leaving the meter running.
Shadow IT - when teams use unapproved services - adds to the problem. This could be a marketing team using an external analytics tool or another group relying on a third-party API without proper oversight. In multi-account setups, where each team manages its own cloud projects, tracking and consolidating spending becomes even more challenging. Without a clear view of where the money is going, it’s tough to identify and address waste.
No Spending Controls or Monitoring
If budget alerts aren’t in place, you won’t notice cost overruns until you receive a surprisingly high bill. A lack of approval workflows for provisioning resources can also lead to runaway expenses. For instance, someone might accidentally launch a high-resource service, leading to a significant and unexpected spike in costs.
Without regular reporting and trend analysis, inefficient spending habits are likely to persist. Over time, these unchecked practices can compound, turning what might seem like minor oversights into a major financial burden. Regular monitoring and proactive adjustments are essential to keep costs under control.
How to Stop Cloud Overspend
Once you've pinpointed where your cloud costs are leaking, it's time to take action. Here are some practical steps to help you tighten control over your cloud spending.
Match Resources to Actual Needs
Start by conducting regular audits of your resources. Look at things like CPU usage, memory needs, and storage patterns across your systems. Tools like AWS Compute Optimizer and Azure Advisor can analyse your usage data and suggest instance types that better fit your requirements, helping you avoid unnecessary expenses.
For workloads with predictable traffic and occasional peaks, consider switching to burstable instances like AWS's T3 or T4g series. These are especially useful for development and staging environments, which often don't need production-level resources. Scaling these down can lead to immediate cost reductions.
Additionally, automating your scaling and scheduling processes can help eliminate waste.
Automate Scaling and Scheduling
Predictive autoscaling uses historical data and scheduled events to handle traffic surges without over-provisioning resources. Set up scaling policies to align with typical business-hour demands.
For non-production environments, schedule automatic shutdowns during evenings and weekends. Development and testing setups can be paused outside working hours without disrupting workflows.
For workloads that run sporadically, like data processing tasks, serverless functions are a cost-effective option since you only pay for actual execution time. Container orchestration tools like Horizontal Pod Autoscaler and Cluster Autoscaler can also dynamically adjust resources to match real-time demand.
Next, focus on cleaning up resources that are no longer in use.
Remove Unused Resources
Unused resources can quietly rack up costs over time. Identify and remove unattached storage volumes, orphaned snapshots, unused IP addresses, and inactive load balancers. These are common culprits for unnecessary charges.
Set up automated policies to delete old snapshots based on your retention needs. Regularly audit your DNS records and CDN configurations to ensure they aren't tied to decommissioned applications.
To catch these issues early, establish robust monitoring systems.
Monitor Costs with Alerts and Tracking
Consistent tagging of resources - using details like project, environment, owner, and cost centre - makes it easier to track spending accurately. Set up budget alerts at different levels, such as overall costs, service-specific expenses, or project budgets. These alerts can warn you of potential overspend before it spirals out of control.
By sharing regular cost reports, you can encourage accountability among teams, helping developers understand how their decisions impact the budget. Real-time monitoring of expenses ensures you’re aware of any sudden spikes in costs as they happen.
Finally, embed cost management into your operational culture.
Adopt FinOps for Continuous Cost Control
FinOps (short for Financial Operations) is a collaborative approach that brings finance, engineering, and operations teams together to build cost awareness into infrastructure planning.
Hold regular reviews with both technical and business stakeholders to discuss spending trends and adjust capacity as needed. By forecasting costs based on planned features and expected growth, you can avoid reactive decision-making after deployment.
Encourage teams to take ownership of their expenses by giving them visibility into their spend and setting clear budgets. Make cost optimisation an ongoing effort by frequently reviewing reserved instances, exploring spot instance opportunities, and staying on top of new ways to save money.
With these steps, you can establish a disciplined approach to managing your cloud expenses effectively.

Manual vs Automated Cost Control: What Works Best
When it comes to managing costs effectively, the choice between manual processes, automated systems, or managed services depends heavily on your team’s size, expertise, and current needs. Each method has its strengths and challenges, and finding the right fit can make a big difference in how efficiently you handle expenses.
Manual cost reviews are all about rolling up your sleeves and diving into the details. This involves regularly auditing your cloud bills, hunting down unnecessary expenses, and making adjustments manually. It’s a great option for smaller setups with predictable workloads, as it gives you complete control. However, it’s not without its downsides - it can be time-consuming, prone to human error, and often reactive rather than proactive.
Automated cost control, on the other hand, leans on software to do the heavy lifting. These tools can monitor spending, flag anomalies, and even fix certain issues on their own. While they’re faster and more efficient than manual reviews, they’re not perfect. Automation can sometimes miss the finer details, so you’ll still need to configure systems carefully and check in periodically to ensure everything’s running smoothly.
Managed services offer a middle ground by combining automation with expert oversight. For organisations where cost management is a critical concern, this approach can ease the internal workload while keeping cloud spending in check.
In practice, many teams find that a hybrid approach works best. For instance, teams with strong DevOps expertise might pair manual reviews with automated alerts to maintain control while boosting efficiency. Meanwhile, organisations with less experience in infrastructure management might lean more heavily on automated tools, supplemented by occasional human intervention for a proactive, round-the-clock solution.
The key is to tailor your approach to your current situation and evolve as your needs grow. Start with straightforward manual reviews and basic automation, then layer on more advanced tools and strategies as your infrastructure and expenses become more complex.
Conclusion: Keep Your Cloud Costs Under Control
