Who stops wasteful cloud spending?
Hi, I'm Jon. Welcome to my blog, where I explain the world of AI and technology in an easy-to-understand way. Today, I'd like to talk about a major challenge facing companies using cloud services: cloud waste. The cloud is a service that allows you to rent resources such as servers and storage over the internet. While convenient, it can easily result in unnecessary costs depending on how you use it. Based on an article from InfoWorld, I'll explain who should prevent this waste and how to prevent it, while also sharing the latest trends for 2025. First, let's understand the current situation and find tips for reducing waste.

The State of the Cloud Market and Spending in 2025
Let's start by looking at the overall picture of the cloud market. According to an announcement by IDC Japan on August 19, 2025, the domestic cloud market is expected to reach 9,708.4 billion yen in 2025, a 29.2% increase from the previous year. This is evidence that cloud usage is expanding rapidly as companies continue to digitalize their operations. The average annual growth rate from 2024 to 2029 is expected to be 14.6%, reaching approximately 19,196.5 billion yen in 2029. These figures show that the cloud has become an indispensable tool for business, but at the same time, it is also true that managing spending is becoming more difficult.
Meanwhile, a post on X (formerly Twitter) predicts that global cloud spending will reach $723.4 billion by 2025. This is primarily directed at major providers such as AWS, Microsoft Azure, and Google Cloud, forcing companies to become increasingly cost-conscious. In fact, an InfoWorld article (related to a post dated around October 3, 2025) points out that wasteful cloud spending is "not a financial issue, but a leadership issue." Many organizations are reportedly surprised by unexpectedly high bills.
Given this background, what are the main causes of wasteful spending? They are unused resources (e.g., idle servers), over-allocated machines, or systems running when they're not needed. If these are left unattended, costs pile up and put pressure on a company's profits. For beginners, it's easy to understand the cloud as a pay-as-you-go system, like electricity. You're supposed to pay only for what you use, but poor management can easily lead to waste.
Examples of wasteful spending
Let's take a look at some specific examples of waste. I've compiled some information from reliable media.
- Idle resources: Virtual machines that are not being used continue to run and incur charges. X's post points out that this accounts for a large portion of cloud waste.
- Over-allocated size: Allocating more specifications (CPU and memory) than necessary. A GO-Global blog post (July 1, 2025) explains that this type of overprovisioning drives up costs.
- Inefficient scaling: Full operation even during off-peak times. NTT East's column (updated March 15, 2023) states that scaling by taking advantage of the benefits of the cloud is the key to cost reduction.
These problems are becoming increasingly apparent in 2025. An article by Datadog Japan (May 14, 2025) introduces a case study in which monthly savings of 1.5 million yen were achieved, demonstrating the effectiveness of using tools to prevent waste.
How to prevent cloud spending waste and who's responsible
So how do we prevent this waste? The InfoWorld article emphasizes that stopping waste is a "leadership role." In other words, the CIO (Chief Information Officer), finance staff, and engineering teams need to work together to manage it. It's not just a technical issue, but cost optimization needs to be embedded in the culture of the entire organization.
As the latest strategies, we will introduce some methods from the 2025 Cloud Cost Optimization Guide (updated October 29, 2024). These can be used on major clouds such as AWS, Azure, and GCP. By the way, when compiling these strategies into documents, the AI tool Gamma is useful. Gamma is a tool that uses AI to instantly create documents and slides, and is easy to use even for beginners.

Practical Reduction Strategies
Here, I've compiled a bullet list of the latest techniques for 2025, collected from posts by X and specialized blogs. All of them are fact-based and can be tried right away.
- Right-sizing resources: Monitor usage and adjust to the minimum required specifications. A post by Mizzle.Fi (June 17, 2025) suggests that automating this process with tools in AWS or Azure is effective.
- Utilizing Spot InstancesUse cheap, ephemeral instances. A Core white paper (October 3, 2025) outlines how this can provide significant savings for Azure users.
- Autoscaling and Shutdown: Turn off resources when not in use. In a post by Dr. Milan Milanović (September 23, 2025), he explains how these simple steps can cut costs without sacrificing performance.
- Introducing cost monitoring tools: Real-time monitoring with tools like Datadog. According to a Mint Group post (October 2, 2025), 78% of companies are losing money due to cloud waste, so optimization will increase ROI (return on investment).
- Multi-Cloud Strategy: Combine multiple providers and choose the cheapest option. An article on Future.ad.jp (as of August 2025) suggests comparing AWS, Azure, and GCP.
When implementing these methods, who is responsible? According to InfoWorld, the ideal situation is for the finance team to take the lead, with engineers handling the practical aspects. Regarding the "2025 Cliff" in 2025 (ATLED survey, October 23, 2024), as large companies move to the cloud, license costs and a lack of human resources will be issues, but these can be resolved by choosing the appropriate pricing method.
Summary and Jon's comments
To prevent wasteful cloud spending, it's important to start by understanding the current situation and then utilize tools and strategies. As the market continues to expand in 2025, the importance of cost optimization is increasing. Why not reconsider your company's cloud usage?
