Turn off unused resources, given that the pricing of the various Azure services is based on the actual use of the resources. For those resources that do not require uninterrupted operation and that allow, without any loss of configurations or data, a deactivation or suspension, it is possible to implement an automation system. This system, regulated by a predefined schedule, facilitates the optimization of use and, consequentially, more economical management of the resources themselves.
Adequately size resources, consolidating workloads and proactively intervening on underutilized resources, allows us to avoid waste and guarantee a more efficient and targeted use of available capacities.
For resources used continuously in the Azure environment, evaluate the option of Reservations can prove to be an advantageous strategy. Azure Reservations offer the opportunity to benefit from a significant cost reduction, which can reach up to 72% compared to pay-as-you-go rates. This benefit can be obtained by committing to pay for the use of Azure resources for a period of one or three years. This payment can be made in advance or on a monthly basis, at no additional cost. The purchase of Reservations can be made directly from the Azure portal and is available to customers with the following subscription types: Enterprise Agreement, Pay-As-You-Go and Cloud Solution Provider (CSP).
To further mitigate costs associated with Azure, it is appropriate to consider the implementation of’Azure Hybrid Benefit. This advantage allows you to achieve significant savings, as Microsoft only allows you to bear the costs relating to the Azure infrastructure, while the licenses for Windows Server or SQL Server are covered by a Software Assurance contract or an existing subscription.

The Azure Hybrid Benefit can also be extended to Azure SQL Database, to SQL Servers installed on Azure virtual machines and SQL Managed Instances. These benefits facilitate the transition to cloud solutions, bidding up to 180 days of dual use right, and help leverage pre-existing investments in terms of SQL Server licenses. To learn more about how to use the Azure Hybrid Benefit for SQL Server, please consult the FAQs present in this document. It is important to note that this benefit is also applicable to RedHat and SUSE Linux subscriptions, further expanding the opportunities for savings and cost optimization.

The Azure Hybrid Benefit can be combined with Azure Reserved VM Instances, creating an opportunity for significant savings that can reach 80% of the total, especially when you opt for an Azure Reserved Instance purchase for the duration of 3 years. This synergy not only makes the investment cheaper, but also maximizes operational efficiency.

Considering the integration of new technologies and the application of architectural optimizations is crucial. This process involves the selection of the most appropriate Azure service for the specific needs of the application in question, ensuring not only optimal technological alignment, but also more efficient cost management.
Allocate and de-allocate resources dynamically is critical to meeting fluctuating performance needs. This approach is known as “autoscaling”, a process that facilitates the flexible allocation of resources to meet specific performance needs at any time. As the workload intensifies, an application may require additional resources to maintain desired performance levels and meet SLAs (Service Level Agreement). On the contrary, when demand reduces and additional resources are no longer essential, these can be de-allocated to minimize costs. Autoscaling capitalizes on the elasticity of cloud environments, allowing not only more effective cost management, but also reducing the administrative burden, as resources can be managed more smoothly and with less manual intervention.
For test and development environments, it is advisable to consider the use of Dev/Test subscriptions, which offer the opportunity to access significant discounts on Azure fees. These subscriptions can be activated under an Enterprise Agreement, thus facilitating more advantageous cost management and more agile and economical experimentation during the development and testing phases.

Conclusions

The adoption of a methodological approach in managing cloud costs, together with the use of appropriate strategies, represents a fundamental pillar for successfully navigating the complex challenge of cloud economic management. Drawing from the principles and techniques outlined in this article, users can not only optimize expenses, but also make the most of their investment in the cloud, ensuring a balance between costs and benefits.
