Cloud Cost Optimization: Practical Tips & Examples

If you're running a busy online store, the cloud's dynamic capabilities can be a great help in keeping up with demand. But as sales soar, so do your cloud costs, threatening your profit margins. Don't fret though, because in this article we'll explore a few quick strategies to rein in your cloud spending while maximizing its great potential.

4 Great tips for saving money

1. Right-size your resources

One of the easiest ways to overspend in the cloud is by provisioning resources that are more powerful (and expensive) than you actually need. It's tempting to err on the side of caution and choose the beefiest instances available but resist that urge!

Instead, start small and monitor your usage. You can always scale up if needed, but you might be surprised at how far you can stretch those smaller, cheaper resources.

2. Turn things off when you're not using them

The beauty of the cloud is that you only pay for what you use, but that also means you're paying for things even when you're not actively using them.

Just like turning off the lights when you go to bed, develop a habit of turning off non-essential resources during off-hours, like development and testing environments. A little bit of downtime can lead to a lot of savings over the course of a month.

3. Embrace reserved instances and spot instances

If you have predictable, steady-state workloads, reserved instances can be a great way to save some serious cash. By committing to a certain level of usage over a 1 or 3 year term, you can secure some steep discounts compared to on-demand pricing.

And for those workloads that can withstand a bit of interruption, spot instances let you bid on unused EC2 capacity at up to 90% off the on-demand price. Just be prepared for your instances to be terminated with little notice if the spot price exceeds your bid.

4. Use cheaper regions for development environment.

One final tip that’s super easy to put into practice is to use cheaper regions for your development and testing environments. While production workloads often require the performance and reliability of premium regions, dev and test environments can usually run just fine on lower-cost alternatives.

By strategically placing non-critical workloads in more affordable regions, you can significantly reduce your overall cloud spend without compromising on the quality of your production environment.

3 Quick practical examples

While these tips are super useful by themselves, it's also really worthwhile to look at some brief real-world scenarios to get a better grip of how things work in practice.

Web Application with Variable Traffic

Let's say you have a web application that experiences significant traffic fluctuations throughout the day. By leveraging Auto Scaling groups and Spot Instances, you can automatically adjust your EC2 fleet based on demand. During peak hours, the Auto Scaling group can add more Spot Instances to handle the increased load, and during lulls, it can terminate idle instances to save costs.

Batch Processing Jobs

Imagine you have a batch processing job that runs nightly, crunching through large datasets. Instead of keeping a dedicated EC2 instance running 24/7, you could launch a Spot Instance just before the job starts, let it churn through the data, and then terminate it when the job completes. You'll only pay for the compute time you actually use, and at a steep discount as well.

Development and Testing Environments

Development and testing environments are prime candidates for cost optimization, as they often don't need to be running around the clock. By scripting the start-up and shutdown of these environments (perhaps using AWS Lambda and CloudWatch Events), you can ensure they're only available during business hours or when actively needed. By automating the process, you also remove the human element and the risk of forgetting to shut down instances, further compounding your savings.

Proven Strategies for Enhanced Savings and Efficiency

So, we can see that cost optimisation in the cloud is not only achievable but actually quite straightforward with the right strategies and a bit of discipline. By right-sizing your resources, turning off idle instances, leveraging reserved and spot instances, and automating the management of your environments, you can realise significant savings without compromising on the power and flexibility of the cloud.

At the end of the day, the key is to be proactive and vigilant. Don't let the promise of the cloud lull you into complacency when it comes to costs. With the tips and examples that we've covered, you're well-equipped to tame your cloud spending and keep your CFO happy. And that, my friends, is a win in anyone's book!
