Why does "invisible waste" occur in cloud expenses? A review guide to avoid continuing to pay for services you're not using

Do you have any of these problems?

"Our cloud and server bills are gradually increasing every month, but no one can explain the breakdown."

"It seems the server created by the previous person in charge is still there, but I can't decide whether it's okay to delete it."

"We don't even have a list of how many servers we're running in-house."

When running a web service or e-commerce site, this situation can sometimes persist for several years. Those who don't have access to the server's internal workings tend to continue paying based solely on the total amount on the invoice, thinking, "I don't understand the technical details."

This article will explain where cloud expenses are wasted and introduce ways to review them even if you don't have technical knowledge

Waste is concentrated on unused contracts and contracts that are too large

Wasted cloud costs can be broadly concentrated in the following two areas:

The first typecontracts that remain active even though the service is not being used. This refers to things like completed test servers or systems created for campaigns that have ended. The second typecontracts that are too large for actual usage. This refers to cases where a high-performance plan was upgraded during a period of high traffic, and the user continues to pay for it even after the traffic has subsided.

Furthermore, these two issues can be identified simply by hiring a specialist to conduct an inventory, without requiring any special skills, making them relatively easy to implement and effective methods

Why is reviewing cloud costs important?

The amount of waste far exceeded expectations

According to the 2026 "State of the Cloud Report" published by research firm Flexera , it is estimated that approximately 29% of corporate cloud spending is wasted (payments that do not actually create value). This percentage has increased for the first time in five years. If you are paying 300,000 yen per month for cloud services, a simple calculation suggests that around 1 million yen per year may be wasted on services that are not being used.

It won't heal on its own if left untreated

Most cloud services operate on a "charge for as long as you're renting" basis. Unlike electricity, where charges decrease if you don't use it, payments continue even if no one is using it unless you cancel or stop the service. A key characteristic of cloud costs is that unnecessary expenses can continue for years simply because "no one notices."

It is also a safety issue

Old servers that are not managed by anyone are left unattended without security updates. These forgotten servers become prime entry points for attackers. Taking stock of expenses also leads to taking stock of security vulnerabilities

Typical patterns that lead to waste

When you hear the word "waste," you might think it's due to poor management by the person in charge, but that's often not the case. Due to the nature of cloud computing, there are structural patterns that tend to occur naturally in any company. Here, we'll introduce four typical examples, along with the reasons why they occur and the signs to look out for

Forgetting to delete a terminated server

This is a case where a temporary server is created for testing a new project or for a campaign website, and then it remains running even after the project is finished. The appeal of the cloud is its ease of use, allowing you to add servers in minutes, but because of that ease, the "record of creation" and the "responsibility for deletion" can easily become ambiguous

This is especially likely to happen when a project is outsourced to an external production company, or when the person in charge is transferred or leaves the company. The psychology of "no one is afraid to delete something whose purpose and who created it are unknown" comes into play, and servers that no one uses remain active for years. If there are items in an invoice whose purpose cannot be explained, it is a sign that this pattern should be suspected

The contract remains fixed because it is too large

Upgrading servers in preparation for TV broadcasts and major sales is a sound decision in itself. The problem is that the upgrades remain in place even after access levels have subsided. Maintaining a contract that's only for peak hours all year long is like ordering lunch boxes every day, only for the busiest day of the year

This issue is often neglected because there's a bias in judgment: "increasing" isn't scary, but "decreasing" is. If a problem occurs immediately after a reduction, the person in charge will be held responsible, so ignoring it becomes the safest option. If there are no records of reviewing the specifications in the past year, there may be a discrepancy between actual usage and the contract

Continuing to use an older generation plan

Cloud services undergo rapid generational changes, and newer generation plans tend to be "cheaper for the same performance." If you haven't reviewed your plan for years since you first implemented it, you might be paying a higher price for an older generation plan when you could be using a more powerful one for the same price

It's a similar situation to smartphone data plans. People who continue using plans from years ago end up paying more than those who sign up now. The same thing happens in the world of servers. However, switching plans requires tasks such as operational checks, so it tends to be put off because people don't want to touch something that's already running. If you haven't changed your plan in more than three years since deployment, it's definitely worth reviewing

Data and backups keep increasing

One easily overlooked issue is the expansion of stored data. Backups and work records automatically grow daily, and without rules for deleting old data, the cost of storage space also increases. It's like a warehouse that keeps adding items without ever discarding anything, constantly renting more shelves

Because the amount per transaction is small, it doesn't stand out on the invoice, but when it accumulates over several years, it becomes a significant amount that cannot be ignored. If your bill is slowly increasing every month even though you haven't changed anything, this pattern is often the reason behind it

Changes before and after the review

Self-assessment checklist

If you cannot immediately answer "yes" to three or more of the following items, it is highly worthwhile to review your approach

• There is a list of servers and cloud services that the company uses in-house
• Is there someone who can explain the purpose of each item on the list?
• I check the monthly invoices, not just the total amount, but also the breakdown of each item
• Have you reviewed your server performance or contract plan within the past year?
• There are rules for deleting testing and campaign-specific mechanisms once they've been used
• The system is designed so that the configuration information can be transferred even if the person in charge leaves the company or is transferred

List of questions to ask the person in charge/external vendors

• Do you have a list of the servers and services currently running? Can you explain the purpose of each?
• What are the top three largest items in your billing breakdown for the past three months?
• Have you reviewed your specifications or contract plan in the past year?
• Are there any items that are not being used or whose purpose is unknown? Can you confirm the impact of stopping them?
• Is there a system in place (frequency, responsible person) for conducting regular reviews?

Things you should know before requesting a review

First and foremost, determining whether it's safe to delete the data is crucial. A server that appears unused may actually be running for monthly aggregation processing. Deleting data based on amateur judgment can lead to business disruption, so always entrust the task to a specialist who can perform impact assessment and backups

Secondly, don't judge solely on the amount of savings. A one-time reduction often leads to a return to the same situation a few years later. We recommend discussing a system for continuous review, including deciding on the frequency of regular reviews and the format of reports from the outset

Thirdly, there's the consideration of costs. While inventory review and analysis do incur certain costs,that surveys show waste accounts for around 30% of expenditures on average, the savings often outweigh the fees. It's reassuring to confirm before signing a contract "what scope of review will be provided" and "how the expected savings will be reported."
