How to compare the total cost of ownership for a cloud solution

Enterprise resource planning (ERP) systems are software applications that integrate various business functions, such as accounting, inventory management, human resources, and customer relationship management. ERP systems can help businesses improve efficiency, reduce costs and enhance customer satisfaction.

However, implementing an ERP system is not a simple task. It requires careful planning, analysis, and evaluation of different options and factors. One of the most important factors to consider is the total cost of ownership (TCO) for a cloud solution.

TCO is a method used to tally the various costs to host, run, integrate, secure, and manage workloads in the cloud over their lifetime. These include fees associated with the resources consumed, such as computing, data transfer, and storage. It also includes integrations with related cloud services, ranging from security and management tools to machine learning and AI. Even calculating personnel costs for cloud engineers can be part of a cloud TCO equation.

To compare TCO for a cloud solution with an on-premises solution for an ERP system, you need to understand the complete functionality required by your application, especially its security requirements and other areas that can add significant costs.

You also need to catalog your current costs with costs that are expected from the cloud. Some of the common cost considerations are:

Physical environment: This includes hardware costs (such as server type, processing power, disk space, and server utilization), network costs (such as latency and network speed), support costs (such as patches and application-level support), and virtualization costs (such as automation and containerization).

Application level: This includes software costs (such as licenses for common software or different licensing options depending on the virtualized environments), integration costs (such as connecting with other applications or data sources), and customization costs (such as modifying or developing features or functionalities specific to your business needs).

Data level: This includes data storage costs (such as capacity, performance, and redundancy), data transfer costs (such as moving data between cloud services or regions), and data security costs (such as encryption, backup, and recovery).

User level: This includes user access costs (such as authentication, authorization, and identity management), user experience costs (such as user interface design and usability testing), and user training costs (such as educating users on how to use the new system).

To calculate TCO for a cloud solution for an ERP system, you need to estimate these cost components over a period of time, usually three to five years. You can use online calculators, spreadsheets, or tools provided by cloud service providers to help you with this process.

However, you should also consider some intangible benefits and challenges that might affect your TCO calculation, such as:

Risk management: Cloud solutions can reduce some risks associated with on-premises solutions, such as hardware failure, power outage, or natural disaster. However, they can also introduce new risks, such as vendor lock-in, data breach, or compliance issues. You need to assess how these risks might impact your business operations and reputation and how you can mitigate them.

Flexibility: Cloud solutions can offer more flexibility than on-premises solutions in terms of scalability, availability, and innovation. You can easily adjust your resource consumption according to your demand fluctuations or access new features and services without investing in additional infrastructure. However, you also need to ensure that your cloud solution is compatible with your existing systems and processes and that you have enough control over your data and performance.

Opportunity cost: Cloud solutions can free up some capital expenditure and operational expenditure that you would otherwise spend on maintaining an on-premises solution. This can enable you to invest in other areas of your business that might generate more value or competitive advantage. However, you also need to account for the potential loss of revenue or market share if you delay or fail to implement an effective ERP system.

Comparing TCO for a cloud solution with an on-premises solution for an ERP system is not a straightforward task. It requires careful analysis of various factors that might affect your business goals and outcomes. By using reliable data sources and tools, you can make informed decisions that will help you optimize your ERP system investment.
