Data Mesh vs Data Fabric: 5 Differences to Know Which One is Best for Your Business

Data management is becoming increasingly complex, and organizations are under pressure to keep up. Traditional approaches to accessing and managing data are complex and rigid, which leads to challenges as data needs and environments evolve. Several new strategies, including data fabric and data mesh, have emerged to help modern data teams handle large and complex data sets across disparate environments.

While both data fabric and data mesh offer an efficient way to manage the massive amounts of data that organizations gather, they do so in fundamentally different ways and have their own strengths and weaknesses. In this article, we define both term, the advantages and disadvantages of each method, and a compare the two to help you determine what works best for your organization.

What are data mesh and data fabric?

The terms sound similar, but they are two clear-cut approaches to handling data that can significantly impact an organization’s ability to process, analyze, and extract value from its data. The primary difference between the two is who controls the data. Both approaches address the growing complexity and scale of data management but from different philosophical and practical standpoints. Data mesh offers a more democratized and distributed model of data ownership, while data fabric enables a unified and automated framework for data integration and management.

Let’s explore the fundamentals:

What is data mesh?

A data mesh architecture is a methodology that treats data as a product. Instead of being centrally managed by an organization’s IT department, individual groups (domains) within the organization manage their own data. The data is decentralized, meaning that the team most familiar with it has control over it. Each domain is responsible for the collection, storage, transformation, and utilization of the data they control.

A data mesh can offer several benefits:

• Domain ownership: Each domain owns and controls the relevant data. This user-centric approach promotes accountability and ensures that the data is well-managed and optimized for easy sharing across the organization.
• Customized data products: The domain provides the data product that other departments in the organization need for specific uses.
• Scalability: A data mesh permits each domain to scale its own architecture, enabling targeted expansion or reduction as needed.
• Data quality: Domains can apply tailored data quality checks based on their specific requirements.

However, there are some things to consider before implementing a data mesh. For example, a data mesh can require a large investment in time and resources. Ensuring that standards and practices are unified across the organization could be more complicated. Applying consistent data security and governance can also pose challenges, and data mesh requires a high level of coordination and communication across domains to prevent unintentional silos. Lastly, an organization is required to prioritize data literacy to ensure that every individual understands and efficiently manages the datasets for which they are responsible.

What is a data fabric?

A data fabric could be considered an opposing approach to a data mesh. Its more centralized data architecture focuses on creating a cohesive and integrated layer of data across an organization. It’s designed to enable unified access to all an organization’s data, regardless of where it resides.

Advantages of a data fabric include:

• Simplified access: Since data is centralized in a data fabric, it’s easier to integrate and consolidate data from disparate sources.
• Centralized governance: A data fabric makes it easier to apply governance and security measures and standardize processes.
• Data virtualization: By enabling a virtual access layer, a data fabric offers access to live data, enabling real-time analytics and insights.

Potential downsides of a data fabric include the initial complexity and cost of setting up the infrastructure and the need for specialized skills to manage and maintain it. Data that goes through a data fabric may be more susceptible to mishandling or breaches, complicating security measures. Consider the capacity of your existing IT resources, which may need to be expanded. Finally, legacy systems may not readily adapt to a data fabric approach.

What’s the difference between data mesh and data fabric?

Understanding the core differences between these two approaches is critical for organizations faced with the choice. Each offers a distinct blueprint for managing, integrating, and utilizing data to drive decision-making and innovation. Here, we’ll go into some of the core differences between a data mesh and a data fabric based on a few important aspects.

1. Data governance and security: Data mesh promotes decentralized governance, where data security and compliance are managed by individual domains that understand their data best. This allows for more tailored governance strategies, but it requires strong coordination to ensure consistency and compliance across the organization. On the other hand, data fabric keeps data centralized, which enhances data governance and security by enabling uniform policies and protections across all data assets. This simplifies compliance management, but customization is limited.
2. Data ownership and management: In a data mesh architecture, data ownership and management belong to specialized domain-specific teams within the organization. The teams act as stewards of their data, encouraging accountability and innovation. However, clear communication and collaboration is necessary to avoid silos and ensure coherence across domains. Conversely, a data fabric concentrates the data’s ownership and management to a central entity. While this enhances efficiency and uniform governance, it may limit domain experts' direct involvement and responsiveness.
3. Suitability: Data mesh is well-suited for organizations that prioritize domain-specific autonomy and have a culture of technical excellence among their teams. It's ideal for companies with complex, distributed data sources and environments where collaboration and ownership by experts are encouraged. Data fabric, on the other hand, best fits organizations that need a unified, enterprise-wide approach to data management, especially for data integration and analysis across diverse systems and platforms. It's excellent for businesses that require centralized control and a cohesive view of their data landscape.
4. Data integration and automation: In a data mesh architecture, each team independently manages and integrates its data, often using specialized automation tools to customize its data products. This provides flexibility and domain-specific optimizations but requires significant coordination to ensure interoperability. Data fabric, by contrast, centralizes the data integration and automation efforts, providing a cohesive framework that spans across all data sources and destinations. It makes sharing data faster and easier across the enterprise, with the trade-off being potentially less customization at the domain level.
5. Data product and design: In the data mesh approach, data is treated as a product, with each domain team responsible for designing, maintaining, and evolving their data products to meet the needs of their consumers. This focus on user-centric design ensures that data products are directly relevant and valuable to their users. A data fabric, on the other hand, centralizes the design and provisioning of data services, aiming for consistency and efficiency across the organization. While this can streamline access and use of data products, it might not always cater to the specific needs of different user groups with the same precision as the domain-specific approach of a data mesh.

Data fabric vs. data mesh: When to choose each

Choosing between a data mesh and a data fabric hinges on your organization’s specific data needs and structural preferences. Data mesh works best for organizations that value autonomy across different teams and have strong collaboration within and between them. Organizations that choose this approach should be equipped to handle the complexities of diverse and decentralized data in their quest to prioritize rapid, domain-specific insights. On the other hand, data fabric is better suited for organizations that need more unified data governance and seamless integration across a variety of data sources, systems, and platforms. A holistic view of the data landscape, as well as consistency and efficiency, are the priorities rather than gaining specialized, up-to-the-minute insights.

For many organizations, there is no one-size-fits-all solution when it comes to their data management strategy. A hybrid approach combines the domain-specific agility of data mesh with the cohesive governance of data fabric, creating a tailored architecture that supports both decentralized innovation and centralized efficiency. This mix-and-match style provides a flexible, balanced data management strategy that meets different requirements across the organization.

Either way, embracing new data strategies requires a thorough evaluation of your existing data landscape and organizational structure. Sufficient cloud storage and computing resources are needed, as well as potentially adopting new data integration and virtualization tools. Additionally, some organizations may need to shift their culture to enable cross-functional teams, allow for increased data literacy, and provide broader access for a more data-centric approach.
