What is Cloud Total Cost of Ownership?

Cloud computing has revolutionized business operations, making it essential for organizations to accurately estimate the cloud Total Cost of Ownership (TCO) of their infrastructure before migration. As companies shift away from the constraints of on-premises computing, they delegate hardware and software management to cloud service providers (CSPs), redirecting resources toward strategic initiatives and innovation. While lower costs are often touted as a primary benefit of the cloud, there are no guarantees.

Despite differences in cost structures between on-premises and cloud computing, both can incur significant expenses. TCO models provide a comprehensive framework for assessing all cost implications of owning and managing assets. While cloud providers typically outline pricing plans at a surface level, a comprehensive evaluation of all resources necessary for deployment and operation is essential for an accurate TCO estimation.

In this article, we explore the definition of TCO, its model, factors influencing it, and the advantages of TCO implementation. Additionally, we delve into the steps for calculating TCO and highlight best practices for cost reduction.

What is cloud TCO?

Cloud TCO is the cumulative expenses associated with adopting, operating, and provisioning cloud services. The complexity of your operations dictates your specific cloud TCO. Initially, estimation focuses on migrating from on-premise to the cloud, then expands to factors like rack rate, compute, data storage, networking, and data transfer costs.

Cloud TCO provides insight into the expenses of hosting, running, integrating, and managing workloads in the cloud.

What is a TCO model?

A cloud TCO model typically comprises two primary cost categories: upfront and ongoing expenses. Upfront costs include the implementation phase of a cloud computing environment, covering planning, assessment, initial fees from Cloud Service Providers (CSPs), data migration, application adaptation, consultant fees, training, and security measures.

Ongoing operational costs include monthly or annual subscription fees charged by CSPs, often based on usage volume and type of services utilized. For instance, data storage rates differ from data transfer or processing fees. Additional charges may apply for upgraded services like advanced analytics or machine learning capabilities. Ongoing training expenses for skill enhancement and maintenance fees, primarily handled by CSPs, contribute to ongoing operational costs.

Factors that affect cloud TCO

Understanding the diverse factors affecting TCO is essential for informed decision-making in cloud adoption. Numerous factors contribute to the overall cost structure, from business characteristics to technical considerations. Here are some key factors:

  • Type of business: Highly regulated industries (finance, healthcare) or those with bursty workloads (media, e-commerce) may require specialized cloud features that impact costs.
  • Training expenses: Upskilling your IT team on cloud technologies adds to the upfront investment but ensures efficient cloud management in the long run.
  • Application complexity: Migrating complex, on-premises applications to the cloud might necessitate code modifications, potentially increasing migration costs.
  • Regulatory compliance: Compliance with industry regulations, particularly around data privacy, may require additional security controls and audits, which can impact your cloud TCO.
  • Infrastructure attributes: The underlying infrastructure of your chosen cloud provider (data center location, security protocols) can influence cloud service costs.
  • Risk management: Implementing robust security measures to protect your cloud environment adds to the initial investment but safeguards your data and minimizes potential security breaches.
  • Operational processes: The business processes migrated to the cloud, such as email and CRM systems, along with supplementary services like cloud automation and disaster recovery provided by your CSP, will impact resource allocation and, consequently, subscription fees for cloud services

Benefits of implementing cloud TCO

While traditional cost accounting typically involves categorizing costs as direct or indirect, fixed or variable, and allocating them to products or departments, it does not consider the entire lifecycle of an asset or the broader implications of its use. The TCO approach differs from traditional cost accounting by emphasizing improved communication between customers and suppliers and offering a holistic view of the IT artifact’s lifecycle. Additionally, TCO facilitates the analysis of individual cost components through a predefined framework, enabling organizations to make informed decisions regarding cost optimization and resource allocation in IT investments. Some of the benefits of transitioning from on-premise TCO to cloud TCO include:

  • Financial transparency: TCO analysis provides a clear understanding of all costs involved in adopting and maintaining cloud solutions, enabling informed budgeting to save your cloud budget.
  • Strategic decision-making: Armed with insights into the long-term financial implications of various cloud options, businesses can make well-informed decisions aligned with their goals and objectives.
  • Cost optimization: Identifying and evaluating cost drivers enables organizations to streamline resource allocation, optimize expenditure, select the right cloud cost management tool, and maximize ROI in their cloud investments.
  • Risk mitigation: By factoring in potential risks and associated costs, TCO analysis facilitates the implementation of effective cloud governance, proactive risk management strategies, minimizing the likelihood and impact of unforeseen incidents.
  • Performance enhancement: TCO assessment enables organizations to identify inefficiencies, eliminate unnecessary expenses, and optimize downtime, ultimately enhancing the performance and agility of their cloud infrastructure.
  • Competitive advantage: Leveraging TCO insights allows businesses to stay ahead of the curve by strategically leveraging cloud resources to drive innovation, improve operational efficiency, and gain a competitive edge in the market.
  • Scalability and flexibility: Understanding the true cost implications of scaling cloud resources empowers organizations to adapt to evolving business needs seamlessly while maintaining cost-efficiency and operational resilience.
  • Enhanced resilience and continuity: TCO assessment enables organizations to invest in disaster recovery and business continuity solutions, minimizing the potential financial losses and operational disruptions resulting from cyberattacks, natural disasters, or system failures.

How to calculate cloud TCO

To calculate the TCO for cloud services, examine various cost elements, including both overt and covert expenditures. Here’s how to determine the total cost of ownership for cloud services:

1. Understand key cost factors

To facilitate an informed comparison of cloud TCO, calculate the total cost of your existing infrastructure. Infrastructure costs typically encompass tangible expenses that are easily quantifiable, though specifics may vary based on your cloud infrastructure.
