IOPS: Database

Relational databases are crucial for many applications, storing and retrieving information in a structured and efficient manner. However, it is crucial to understand that inserting unnecessary logs and data into these databases can result in serious consequences for performance, storage, and data retrieval. In this technical article, we will examine the problems associated with the practice of writing non-transactional data to productive and high-performance databases.

 

1. Storage Impact

Storing unnecessary data in relational databases can quickly consume precious storage resources. Inserting extensive logs and non-transactional data increases the total size of the database, leading to a greater need for disk space. Excessive storage can cause space management issues and slow down read and write operations, compromising the overall performance of the database.

2. IOPS Consumption (Input/Output Operations per Second)

Writing unnecessary logs and data also affects IOPS consumption. In high-performance transactional databases, the available IOPS quantity is a critical resource. These input/output operations are limited and easily depleted when there is a high volume of non-essential writes. Excessive IOPS can lead to delays in database operations, impairing application responsiveness and the end-user experience.

3. Recovery Time (Data Restore)

In case of severe system failure or a more significant outage, the database’s recovery time (data restore) can be significantly affected. Unnecessary data makes the restoration process slower and more complex, prolonging the time required to recover the entire database. This can result in extended downtime, negatively impacting service availability and the user experience.

Recommendations and Best Practices

To avoid the aforementioned problems, it is important to follow some best practices when working with relational databases, especially in productive and high-performance environments:

1. Adequate Database Design:

 Carefully plan the database design, clearly defining which information needs to be stored and which is genuinely necessary for transactional operations.

2. Appropriate Logs:

Record only essential and relevant information in the database log. Avoid extensive logs that contain non-crucial data for failure recovery or auditing of important operations.

3. Separate Storage:

Consider storing logs and non-transactional data in separate systems or files, outside the main relational database. This helps avoid overloading the production database and simplifies the data recovery process.

4. Monitoring and Optimization:

Regularly monitor database performance and implement adjustments when necessary. Optimizations, such as proper indexing and regular cleanup of unnecessary data, help maintain system efficiency and performance.

Writing unnecessary logs and data in relational databases can have a significant negative impact on performance, storage, and data retrieval in the event of severe failures. It is crucial to follow best practices and take a careful approach when designing and managing databases in productive and high-performance environments. By doing so, we ensure system efficiency, continuous service availability, and a positive experience for users.

 

Financial Impact: Cost Savings in the Cloud

 

In addition to the technical aspects discussed above, it is essential to note that avoiding high IOPS consumption and excessive disk usage can also have a significant impact on hosting costs in the cloud, such as in AWS (Amazon Web Services) or Azure (Microsoft Azure). Both cloud platforms offer pricing models based on resource consumption, making resource optimization a priority to ensure financial efficiency.

1. IOPS Costs

Most cloud providers, such as AWS and Azure, charge for the IOPS consumed by storage services. If a database is performing many I/O operations due to a high volume of unnecessary writes, the associated cost can increase significantly. Uncontrolled IOPS usage can lead to higher bills, as cloud providers offer provisioning options that may incur additional fees.

2. Disk Storage Costs

Cloud storage services are also billed based on the amount of storage space used. If the database is storing unnecessary data, the total storage size will increase, resulting in a higher cost. Additionally, some cloud providers offer storage options with different performance levels, where high-performance storage incurs higher costs. Avoiding unnecessary storage can help reduce expenses associated with this component.

3. Resource Optimization

Resource optimization in the cloud is crucial to keep costs under control. By adopting practices that avoid high IOPS consumption and excessive disk usage, organizations can improve financial efficiency in their cloud environments. This includes implementing data management strategies to ensure that only essential information is stored in the database and maintained efficiently.

4. Proper Scaling

Properly scaling cloud resources is another crucial aspect of cost optimization. Based on performance requirements and expected workloads, it is possible to select the correct service options that best fit the application’s needs and ensure that resources are not over-provisioned, which would also lead to excessive costs.

Avoiding high IOPS consumption and excessive disk usage in relational databases not only improves performance and data recovery in the event of failures but can also have a positive financial impact when hosting in the cloud, whether in AWS, Azure, or other providers. Adopting practices that optimize resource consumption helps keep costs under control and ensures overall financial efficiency, allowing organizations to get the most out of their cloud environments, achieving optimal performance and value for their investments.
