Mistakes that cause small businesses to 'go over budget' when using AWS.

In the wave of digital transformation, many SMEs in Vietnam are choosing AWS to increase flexibility, but many businesses are quickly finding themselves in a situation where costs are getting out of control.

The cost problem is not as simple as expected.

AWS offers a significant advantage with its 'pay-as-you-go' model, eliminating the need for businesses to invest in initial infrastructure. However, this flexibility can also become a double-edged sword if businesses lack a suitable management strategy.

The AWS cost problem isn't as simple as expected.

According to technology experts, cloud costs stem not only from actual resource usage but are also influenced by system configuration, operation, and monitoring. For SMEs – which often have limited access to highly skilled IT personnel – the risk of unexpected costs is even greater.

Common mistakes

1. Allocating resources beyond demand.

One common mistake is choosing a server (instance) configuration that is higher than necessary. Many businesses tend to 'over-prepare' to avoid service disruptions, but this results in significantly higher costs than actually needed.

2. Do not disable or optimize unused resources.

Resources like EC2, RDS, or storage continue to incur costs if not shut down or optimized when not in use. This is a common reason for unexpected AWS bill increases, especially in development/test environments.

3. Choosing the wrong pricing model.

AWS offers various pricing models such as On-Demand, Reserved Instances, and Savings Plans. However, many SMEs only use On-Demand due to its simplicity, overlooking more cost-effective long-term options.

Choosing the wrong pricing model is one of the mistakes when using AWS.

4. Lack of tools for monitoring and alerting on expenses.

Failing to set up cost tracking tools like AWS Cost Explorer or Billing Alerts prevents businesses from detecting anomalies in a timely manner. By the time they realize it, costs have often far exceeded initial estimates.

5. Lack of a system architecture strategy

A system that isn't optimally designed from the outset can lead to inefficient resource utilization. For example, failing to take advantage of auto-scaling or using the wrong type of storage can significantly increase operating costs.

When does AWS really become 'expensive'?

In reality, AWS isn't always expensive. The issue lies in how it's used. If deployed and managed correctly, the platform can help SMEs save significant costs compared to traditional infrastructure. Conversely, without proper control, costs can increase exponentially.

This is also why more and more businesses are paying attention to the problem of optimizing AWS costs for SMEs as an important part of their technology operations strategy.

What direction should SMEs take?

To avoid exceeding their budget when using AWS, experts recommend that businesses should:

• Accurately assess usage needs before implementation.
• Choose the appropriate pricing model for each workload.
• Establish a cost monitoring and alerting system.
• Regularly review and optimize resources.
• Develop a flexible and cost-effective system architecture.

However, for many SMEs, carrying out all these steps themselves is not simple due to limitations in resources and experience.

In this context, specialized cloud consulting firms are becoming the preferred choice for many businesses. Instead of figuring things out on their own, SMEs can leverage the experience of their partners to build a more effective implementation roadmap and optimize costs.

In Vietnam, Renovacloud is one of the leading providers of AWS consulting and optimization services for businesses. According to a representative from the company, most SMEs seek their services when costs have spiraled out of control and can save 20-40% after system review and optimization.

In addition to cost auditing, companies like Renovacloud also assist with architectural design, selecting appropriate pricing models, and setting up real-time cost monitoring systems.

AWS offers numerous opportunities for SMEs to enhance their technological capabilities, but it also presents significant challenges in cost management. Understanding common mistakes and developing appropriate strategies will help businesses maximize the benefits of the cloud while avoiding unnecessary financial risks.
