Cloud infrastructure is powerful, scalable, and flexible—but like any utility, costs can spiral out of control if not properly managed. Whether you’re a small business taking its first steps into the cloud or a larger organisation looking to rein in runaway expenses, optimising cloud costs can make a big difference to your bottom line.
Here’s how to manage and optimise your cloud infrastructure costs, without getting bogged down in jargon.
1. Understanding What You’re Paying For
Before diving into strategies, it’s important to know what you’re paying for. Cloud services are usually billed on a pay-as-you-go basis. That means you’re paying for the resources you consume, whether that’s storage, processing power, or bandwidth.
Common cost areas include:
Compute costs: Charges based on how much CPU and memory you use.
Storage costs: Based on the amount of data you’re storing and how often you access it.
Data transfer costs: Moving data between regions or out of the cloud can incur charges.
Licensing fees: Costs for any software licences you’re running on your cloud servers.
2. Right-Sizing Your Resources
One of the easiest ways to cut cloud costs is by making sure you’re not paying for more than you need. Cloud providers allow you to customise how much compute power, memory, and storage you need—so make sure you're not over-provisioning.
Right-sizing involves adjusting your cloud resources to match your actual needs. For instance, do you really need a high-performance server running 24/7 when a smaller, cheaper instance will do the job? Start with tools like AWS Cost Explorer or Azure Advisor, which analyse your usage and recommend optimisations.
According to Flexera’s 2023 State of the Cloud report, nearly 32% of cloud spend is wasted on unused or over-provisioned resources. By right-sizing, businesses can immediately reduce their monthly cloud bills.
3. Leverage Autoscaling for Seasonal or Variable Loads
Many businesses have fluctuating workloads—whether due to seasonal sales or unpredictable demand spikes. Instead of paying for high-capacity infrastructure that goes underused for most of the year, you can use autoscaling. Autoscaling automatically adjusts your cloud resources based on demand, scaling up when needed and scaling down during quiet periods.
Google Cloud, AWS, and Azure all offer autoscaling features, and when set up correctly, they can prevent you from paying for idle resources. This is particularly useful for businesses that see a surge in traffic during holidays, sales events, or peak periods.
4. Use Reserved Instances or Savings Plans
If you’re committed to using a particular cloud provider for the long term, consider reserved instances or savings plans. These allow you to commit to using a certain amount of cloud resources over a fixed period (usually 1 or 3 years) in exchange for significant discounts—up to 72% in some cases.
A 2022 Gartner study found that businesses using reserved instances for predictable workloads saved an average of 20-40% compared to pay-as-you-go pricing.
However, this approach only works for stable workloads. If your needs fluctuate unpredictably, it’s better to stick with flexible, on-demand pricing.
5. Set Budgets and Use Cost Monitoring Tools
Cloud platforms offer a variety of budgeting and monitoring tools to help you keep track of spending in real-time. Set up budget alerts so you get notified if you’re approaching your monthly limit. AWS, Azure, and Google Cloud all have native tools that let you set thresholds and track spending patterns.
Cloud cost optimisation isn’t just about reacting to big bills—it’s about constantly monitoring and tweaking your setup to match usage. If you wait until the end of the month to check your bill, it’s already too late.
6. Use Spot Instances for Temporary Workloads
Need extra compute power but want to avoid high costs? Spot instances allow you to purchase unused cloud capacity at discounted rates—up to 90% cheaper than on-demand pricing. The catch? Cloud providers can reclaim these instances with short notice, making them best suited for non-critical tasks like batch processing or data analysis.
Amazon’s AWS and Google Cloud offer spot instances, and businesses that have adopted this strategy have seen substantial savings, especially for workloads that can tolerate interruptions.
7. Implement Cloud Governance Policies
It’s easy for teams to spin up cloud resources without thinking about the cost. Implement cloud governance policies to prevent wasteful spending. This includes defining who can provision resources, setting budget limits for departments, and enforcing tagging policies to track spending by project or team.
A 2023 Flexera report highlighted that organisations with clear cloud governance saved an average of 25% on cloud spend, primarily by reducing unnecessary resources and implementing accountability.
8. Review and Optimise Storage Costs
Storage is one of the biggest culprits for runaway costs, particularly if you’re storing large amounts of data. Consider using tiered storage to keep your costs down. For example, data that’s accessed frequently can sit in higher-cost storage (hot storage), while older, rarely accessed data can be moved to lower-cost options (cold storage).
According to AWS, businesses that adopt tiered storage solutions reduce their storage costs by 30-50%, depending on their data usage patterns.
9. Avoid Data Egress Fees
Data egress charges (moving data out of the cloud) can catch businesses off guard. Make sure you’re aware of where and how your data is being moved. Whenever possible, keep data transfers within the same cloud region to avoid hefty fees.
In 2023, businesses moving large amounts of data across regions faced additional costs of up to 30% due to egress fees. Minimising inter-region data transfers can significantly cut your overall cloud spend.
10. Review Usage Regularly
Finally, regular reviews are key. Schedule a quarterly or monthly review of your cloud usage to identify areas where costs can be optimised. Consider assigning a team or partner like SystemsCloud to monitor and optimise your usage. With their expertise in managed services, they can help you spot cost-saving opportunities and manage your cloud infrastructure efficiently.
Closing Thoughts
By combining these strategies—right-sizing, autoscaling, reserved instances, spot instances, and cost monitoring—you’ll be well on your way to optimising cloud costs while maintaining performance and flexibility. Keep a close eye on your usage, and regularly review your setup to avoid paying for resources you don’t need.
Cloud infrastructure doesn’t have to be expensive, and with the right cost management, your business can enjoy all the benefits without breaking the bank.
