Cloud Cost Optimisation Guide and How We Do It

Arrows that show how costs are going down for AWS cloud.

Moving your software to the cloud may feel like leasing a Manhattan loft with a view over Central Park: it’s good for your heart & soul but bad for your wallet. And soon enough, maintaining this lifestyle gets out of hand, and the bills suddenly stop making sense... and you just want all of it to stop.

Let me tell you, keeping track of your infrastructure budget is tough, especially for a growing business. In fact, it's so common that according to a report published by Anodot, nearly half of the businesses (49%) find it difficult to get cloud costs under control, and 54% believe their primary source of cloud waste is a lack of visibility into cloud usage.

But worry not: in this article, I'll guide you through how we at Team Serverless think it's best to go around optimizing your cloud costs.

And if you need more than an article, we briefly describe how we help our clients with cloud cost optimization in the Milnorway case study, where we were migrating a product from a Chinese cloud platform to AWS Serverless.

So, What is Cloud Cost Optimization?

As you may have guessed from the headline, cost optimization is about ensuring you get value for money with no hidden costs or unused pricey cloud services. It involves implementing strategies and practices to effectively use your resources, manage spending and ensure your company gets the most out of its cloud investment.

By optimizing cloud costs, you can maximize ROI, ensure cost-effective operations, and allocate resources more efficiently.

Here are some of the activities involved in cloud cost optimization we implement for our clients:

  • Analyse and adjust allocated resources

    You have to rightsize your cloud resources, such as compute instances, storage, and databases, to match the workload requirements. This prevents overprovisioning or underutilization of resources, leading to cutting costs.

  • Look into Reserved Instances and Saving Plans

    Educate yourself about the pricing models cloud service providers offer, such as AWS Reserved Instances or Azure Reserved VM Instances, to commit to longer-term usage and benefit from discounted pricing.

  • Enforce Auto Scaling

    Implement automated scaling mechanisms to adjust the number of cloud resources based on demand, ensuring optimal resource utilization and cost efficiency during peak and off-peak periods.

  • Optimise Cloud Storage

    Put techniques like data tiering, compression, and deduplication into practice to reduce storage costs while maintaining data accessibility and performance.

  • Achieve Cost Visibility

    Establish governance policies, monitoring tools, and cost allocation mechanisms to gain visibility into cloud spending, track costs by projects or departments, and enforce cost control measures.

  • Plan Capacities

    Study historical usage patterns and plan for future growth projections to effectively plan and purchase reserved capacity in advance, avoiding last-minute purchases at higher prices.

  • Adopt FinOps Practices

    Establish collaboration between finance, operations, and development teams to align cloud spending with business objectives, track costs, and make data-driven decisions.

Cloud cost optimization is an ongoing process that requires continuous monitoring, analysis, and adjustment of cloud resources and usage patterns. By implementing effective cost optimization strategies, companies can achieve significant savings, improve cost predictability, and optimize their cloud expenditure without compromising performance or functionality.

Cloud Pricing Models

For starters, let’s look at the most common cloud pricing models.

  • Pay-as-you-go (PAYG)

    In this model, users get billed based on the actual usage of cloud resources, such as compute instances, storage, data transfers, and other services, on an hourly, monthly, or per-usage basis. It offers flexibility and cost control by aligning costs with actual usage. And most of all, it's also our personal favorite. We like to ensure our clients pay for what they use now and not a penny more.

  • Reserved Instances (RI)

    This model is about specific terms and predicted usage. It allows companies to reserve cloud resources for a particular period (e.g., 1 or 3 years) at a significant discount compared to the pay-as-you-go rates. It's suitable for companies that have predictable workloads and want something long-term.

  • Dedicated Instances

    With this, you get a dedicated physical server for exclusive use. These are ideal for compliance, security, and performance-sensitive workloads, but they usually come at a higher cost than shared instances.

  • On-Demand Instances

    This is similar to the pay-as-you-go model, where you use and pay for resources without any upfront commitment. This pricing model typically charges you at regular rates with no long-term obligations or discounts.

  • Spot Instances

    Some cloud providers offer their customers to bid on unused or spare cloud resources. This may seem attractive when the price is low, but once the market price exceeds your bid, these instances can be terminated on a terse notice. So it's a pretty risky choice.

  • Free Tier

    This is perfect if you want to explore and experiment with cloud platforms without incurring any overcharges. In this model, cloud providers offer limited resources and services for a short time to test them out. Free Tier is usually aimed at new customers or small-scale cloud usage.

  • Adopt FinOps Practices

    Establish collaboration between finance, operations, and development teams to align cloud spending with business objectives, track costs, and make data-driven decisions.

    If you still need to decide what pricing model and service provider to choose, schedule a call, and we will help you.

Common Cloud Cost Drivers

Okay, now that cloud pricing models got covered, let's move on to the most common cost drivers that lead to overspending if not appropriately managed.

At Team Serverless, we recognize two types of reasons: one has to do with how an organization is structured, and the other has to do more with cloud resources & providers. Let's take a look:

To understand how to approach cloud cost optimization, you have to understand the common cloud cost drivers.
  • Improper Pricing Model Selection

    Pretty obvious, but I have to put it out here because it gets overlooked quite often: choosing the wrong pricing model for cloud services results in overspending. For example, opting for on-demand instances instead of reserved instances for stable workloads will dry your budgets over time.

  • Lack of Usage Monitoring and Governance

    Poor visibility into cloud resource usage can make it challenging to identify overspending areas. Crazy, right? But also difficult to keep in mind. Monitoring cloud services and implementing proper governance practices, such as tagging resources, is necessary to track and optimize costs. Enforce these practices from the start to spend wisely.

  • Inadequate Cost Allocation

    Hanging money on a growing project takes a lot of work. You want the best, the fastest, the most scalable of them all. Without proper cost allocation practices, it becomes difficult to attribute costs to specific teams, projects, or departments. This lack of granularity can lead to overspending without clear accountability.

  • Lack of Cost Optimization Strategies

    Failing to implement cost optimization strategies, such as rightsizing resources, using spot instances or spot blocks, implementing caching mechanisms, or leveraging cost-effective alternatives, leads to overspending. And I know doing all this homework and addicting additional steps to your checklists can be a pain. But trust me — the result is worth it.

  • Unused Resources

    This is first and foremost. If you want to know where your precious money goes, check for instances, storage, and other running cloud services that have yet to actively serve any purpose. Just like Liam Nison said — find them and end them.

  • Overprovisioning

    It’s simple: don’t bite more than you can chew. It's essential to accurately assess the required capacity and choose appropriately sized instances and storage to avoid paying for resources you don’t use.

  • Lack of Resource Optimization

    Using your resources inefficiently leads to increased costs. So to avoid that, you must establish some ground rules and include performance audits and optimization in your quarterly plans.

  • Data Transfer and Network Costs

    Excessive data transfer between different services, regions, or external networks can contribute to overspending. Check for inefficient data transfer patterns, unoptimized network configurations, or unnecessary bandwidth allocation to save up.

  • Unoptimized Storage

    Are you using your storage efficiently? Check for whether you're storing redundant or infrequently accessed data in expensive storage tiers, as it can really cut down that check at the end of the month. To optimize your storage costs further, employ data lifecycle management strategies and ensure you're utilizing the appropriate storage classes.

  • Complex Pricing Structures

    Let's be honest, with an abundance of cloud providers & offers like various pricing models, discounts, and pricing tiers, it's not easy to find what matches your needs. But Team Serverless is always here to consult if you need some advice. Just give us a call.

Cost Performance Indicators to Keep an Eye On
