Evaluating the Total Cost of Ownership (TCO) for Cloud Solutions in 2023

‍Developing an accurate understanding of the Total Cost of Ownership (TCO) for cloud solutions is crucial for businesses contemplating a shift to cloud-based infrastructure. The TCO provides a comprehensive view of the expenses associated with both the migration to the cloud and the operation of cloud-based systems. This article will delve into the various components of cloud TCO, methods for calculating it, and strategies for optimizing cloud costs.

Understanding Total Cost of Ownership (TCO) in Cloud Computing

The Total Cost of Ownership (TCO) in the context of cloud computing encapsulates all the costs associated with the establishment and operation of cloud infrastructure. This cost model takes into account the costs of the underlying infrastructure, including computing power, data transit, and storage, as well as the costs associated with maintaining and managing cloud services.

The TCO model is commonly used to assess the cost of static resources over their lifetime. However, in the dynamic and ever-evolving landscape of cloud computing, predicting future costs presents a unique challenge.

It is crucial to understand that the costs associated with an on-premise system and those for a cloud-based solution are not directly comparable. The dominant costs in an on-premise infrastructure are the initial purchases of hardware and software, whereas cloud computing costs are typically based on monthly subscriptions or pay-per-use models.

To develop an accurate TCO for cloud solutions, it's essential to consider both the direct costs and the indirect or intangible costs associated with each approach.

Calculating the TCO for Cloud Solutions

The total cost of ownership for a cloud solution can be influenced by various factors, including the nature of your organization, the functions supported by the cloud solution, performance requirements for cloud workloads, and the costs associated with training and risk management.

When calculating cloud TCO, it is important to understand your current IT infrastructure costs. This involves calculating the direct and indirect costs of running and maintaining your current system, as well as estimating your current workloads.

Some of the cost areas to consider when calculating your current IT infrastructure costs include:

  • Hardware and Infrastructure: This includes the cost of physical servers, supplies, spare parts, and other hardware associated with your on-premise system.
  • Data Center: The cost of powering your data center and meeting your current cooling, power, and space requirements.
  • Software: The cost of current software usage, including the number of licenses and the cost of these licenses.
  • Personnel: The cost of all personnel involved in system, network, and database administration.
  • Disaster Recovery: If you have a disaster recovery system in place, you need to consider the cost of maintaining and managing that site.
  • Maintenance: The cost of servicing, operating, and maintaining the system, including both in-house and outsourced maintenance.
  • Upgrades: The potential cost of upgrading the system if the need arises.
  • Security: The total cost of securing your current system, from physical security to firewalls and security experts.
  • Hidden Costs: The cost of downtime and other unforeseen expenses.

Next, you need to estimate the cost of a cloud solution. This involves calculating the cost of operating your applications in the cloud. It's important to note that a cloud solution is not inherently cheaper than on-premise infrastructure.

The cost of a cloud solution will depend on factors such as migration costs, the monthly cost of your selected cloud services, and consultation and training costs.

Considering the Intangible Benefits of The Cloud

Beyond comparing the monetary costs of on-premise versus cloud solutions, it's also important to consider the opportunity costs and intangible benefits associated with switching to the cloud. These may include:

  • Innovation: The cloud offers hundreds of services that can be accessed on demand, allowing developers to move fast and respond quickly to market changes.
  • Elasticity: The cloud allows for easy deployment of additional instances to handle peak loads without downtime.

Comparing On-Premise TCO to Cloud TCO

When performing a cloud TCO analysis, a few key points should guide your interpretation of the results:

  • Cloud computing is not inherently cheaper than an on-premise model.
  • Cloud adoption often results in a larger ROI and better business outcomes, not necessarily a lower TCO.
  • Comparing the business value and opportunity cost of switching to the cloud versus using an on-premise model is just as important as comparing head-to-head costs.
  • Identifying cost savings and efficiencies is crucial when performing a cloud TCO analysis.

Lowering Your Cloud TCO

To ensure a lower TCO for cloud computing in the long run, it's important to apply best practices for cloud cost optimization. These can include:

  • Using cost management tools to track and control cloud costs.
  • Choosing the most cost-effective infrastructure for your needs.
  • Implementing governance policies to monitor and control the use of cloud resources.
  • Dynamically applying pricing plans to ensure the optimal cost structure for each workload.
  • Managing orphaned resources to reduce waste and improve utilization.
  • Managing over-provisioned resources to ensure they are properly utilized.

Cost optimization is now a key part of migrating to the cloud. Cloud providers are developing native optimization options to help you choose the most cost-effective infrastructure for your needs. There is also a growing market for third-party cost optimization tools, especially for multi-cloud environments.

Cost Control and Cloud Financial Management

Once you have migrated to the cloud, it's important to maintain cost control and optimize spending to avoid waste and unexpected costs. This is where cloud financial management, or FinOps, comes into play. FinOps promotes collaboration between DevOps and financial teams, helping to maintain visibility over costs and make informed decisions about the use of cloud resources.

Case Study: Metinvest's Migration to Azure

A prominent example of successful cloud migration is Metinvest, an international steel manufacturer and mining corporation. In less than a year, Metinvest moved its 680 servers and 240 TB of data from two local data centers to the Azure cloud platform. The project, which involved re-platforming programs for best cloud utilization, resulted in expected savings of USD 3 million over the following ten years.

Metinvest's successful migration to Azure demonstrates how a strategic approach to cloud migration, coupled with the right tools and support, can result in significant cost savings and operational efficiencies.


In conclusion, understanding the Total Cost of Ownership (TCO) for cloud solutions is crucial for businesses considering a shift to cloud-based infrastructure. By taking into account all relevant costs, including those associated with infrastructure, licensing, support, and training, businesses can make informed decisions about their cloud migration strategy and evaluate the potential cost savings and benefits of adopting a cloud solution. By leveraging TCO assessment tools and considering the unique needs of your organization, you can determine the cost implications and potential savings of adopting the cloud.
