Continued Preference for In-House Data Centers: Security, Control, and Customization among Key Factors

In the era of cloud computing, one may assume that in-house data centers would become obsolete. However, despite the rise of public cloud services, many companies still choose to invest in their own hardware and software. This article explores the reasons behind this preference for in-house data centers and highlights the advantages they offer in certain industries.

The Growth of Cloud Computing

Before delving into the reasons for the persistence of in-house data centers, it’s crucial to acknowledge the growth and popularity of cloud computing. Over the past decade, businesses worldwide have significantly increased their spending on external or public cloud services. In fact, global expenditure on these services reached nearly $230 billion in the previous year, a substantial increase from less than $100 billion in 2019[^1^].

Leading cloud service providers like Amazon Web Services (AWS), Google Cloud Platform, and Microsoft Azure have experienced remarkable revenue growth, with annual increases exceeding 30%[^1^]. These providers have also been at the forefront of developing cutting-edge artificial intelligence (AI) tools, benefiting from their vast resources.

The Persistent Appeal of In-House Data Centers

Despite the rapid growth of cloud computing, companies continue to invest in their own data centers. In 2022, these investments surpassed $100 billion for the first time[^1^]. This trend is particularly prominent in the industrial sector, where in-house computing offers unique advantages. Let’s take a closer look at why companies are still drawn to in-house data centers.

Retaining Control and Confidentiality

One significant advantage of in-house data centers is the ability to maintain control and confidentiality over sensitive information. Many companies prefer to keep the data they use to train AI models close to their chest, rather than relying on third-party cloud providers. By managing their own data centers, businesses can have full control over access and security measures, reducing the risk of data breaches and unauthorized access.

Real-Time Analysis and Reduced Latency

In certain industries, real-time data analysis is crucial for maintaining operational efficiency and detecting problems promptly. For example, manufacturing companies are increasingly relying on “digital twins” of their factories to identify issues, minimize downtime, and improve overall efficiency. These digital replicas require immediate data analysis and minimal latency, which can be challenging to achieve with public cloud services. By having in-house data centers, companies can ensure that data analysis occurs in real-time without delays caused by data transfer to remote cloud servers.

Data Sovereignty and Localization

Data sovereignty, which refers to the concept of data being subject to the laws and regulations of the country it resides in, has become a significant concern for many businesses. Governments are increasingly implementing data localization laws to prevent data from crossing borders. For example, China and India have enacted data sovereignty laws, primarily affecting financial companies. By operating their own data centers, companies can comply with these regulations and avoid potential legal complications associated with cross-border data transfer.

Enhanced Performance and Reliability

In certain scenarios, particularly those involving critical processes or services, in-house data centers offer superior performance and reliability compared to public cloud services. Public cloud providers often have data centers located far from the source of their customers’ data. Transferring data over long distances can introduce delays and increase the risk of service outages. For data-intensive tasks that require real-time processing, such as AI model training, having an in-house data center allows companies to achieve optimal performance and minimize potential disruptions.

Options for In-House Data Centers

Companies that opt for in-house data centers have several options to choose from, depending on their specific requirements and resources. Let’s explore some of these options:

Building and Operating In-House Data Centers

One approach is for companies to build, equip, and operate their own data centers entirely. This option allows for maximum control and customization but requires significant upfront investments and ongoing maintenance. Some companies, such as Vertiv and Schneider Electric, offer small modular data centers that can be installed on or near industrial sites, connected to data sources via 5G networks[^1^]. This option provides flexibility and scalability, especially for companies with evolving data needs.

Renting Data Center Space

An alternative option is to lease space in a data center owned and managed by a third party. Tenants typically bring their own computing and networking equipment while the data center provider takes care of physical security, power supply, and cooling. This option is particularly attractive for companies that prefer not to bear the responsibility of data center construction and maintenance. Leasing data center space offers scalability, as businesses can adjust their space requirements based on their evolving needs.

Hybrid Approaches

Many companies adopt hybrid approaches, combining elements of both in-house data centers and public cloud services. This approach allows businesses to leverage the benefits of in-house data centers for critical and time-sensitive processes while using public cloud services for less time-critical workloads. By utilizing both options strategically, companies can achieve a balance between control, performance, scalability, and cost-effectiveness.

Industry Examples

Several industrial companies have embraced in-house data centers to support their unique requirements. Let’s explore some notable examples:


Volkswagen, a leading German carmaker, has recognized the advantages of in-house data centers for its manufacturing processes. By having their data centers close to their factories, Volkswagen can ensure minimal latency and real-time data analysis. This proximity also allows the company to comply with local data sovereignty regulations and maintain control over its data.


Caterpillar, an American manufacturer of heavy equipment, relies on in-house data centers to support its operations. By having their data centers on-site, Caterpillar can analyze data from their equipment in real-time, enabling predictive maintenance and improving the overall efficiency of their products. This approach ensures minimal latency and enhances the reliability of their data-driven processes.


Fanuc, a Japanese manufacturer of industrial robots, also embraces in-house data centers to support its operations. By analyzing real-time data from their robots and factories, Fanuc can optimize their manufacturing processes, detect issues promptly, and minimize downtime. The proximity of their data centers to their production facilities enables efficient data analysis and enhances the reliability of their operations.

Future Trends and Challenges

While in-house data centers continue to be preferred by certain industries, there are several factors that may shape their future. Here are some important trends and challenges to consider:

Rising Costs and Construction Delays

The costs of power, land, materials, and labor are on the rise, affecting the construction and maintenance expenses of in-house data centers. Construction delays have also become a common challenge, potentially impacting the timeline and budget of data center projects. Furthermore, upgrading data centers to support AI capabilities can be costly, as specialized AI servers are considerably more expensive than general-purpose servers.

Cloud Providers Expanding Their Reach

Public cloud providers are aware of the advantages offered by in-house data centers and are taking steps to address some of the limitations of their services. For example, they are building data centers in new locations to reduce latency and improve proximity to customers’ data sources. Some providers, like AWS, are even offering prefabricated data centers similar to those offered by companies specializing in in-house data centers.

The Role of AI

As AI continues to advance, its integration with data center operations will become increasingly important. AI can optimize data center efficiency, predict equipment failures, and automate routine tasks. By harnessing AI capabilities, companies can enhance the performance, reliability, and cost-effectiveness of their in-house data centers.


Despite the tremendous growth of cloud computing, in-house data centers still hold significant appeal for many companies, particularly in industries with unique requirements.
