Is data fabric the same as data mesh? Let’s explore
The data mesh is a design concept that’s more about people and processes, whereas the data fabric is an architecture to tackle data and metadata complexity. Let’s explore the approaches further.
Data mesh is a new approach coined by Zhamak Dehghani that advocates for decentralized data architecture.
The data mesh suggests that each business domain is responsible for hosting, preparing, and serving its data to its own domain and larger audience. This allows flexible and autonomous data teams to build and manage their own data products, promoting data ownership and accountability.
Gartner calls it a solution architecture for the specific goal of building business-focused data products.
Data fabric is a centralized approach to data architecture. Gartner calls it a design concept that serves as an integrated layer (fabric) of data and connecting processes.
The data fabric advocates for setting up a unified data layer to provide a single source of truth for data. This ensures data quality, consistency, and security while allowing different teams to access and manage data easily.
It’s crucial to note that the data fabric is different from a data warehouse or a data lake. Here’s how James Serra puts it:
“A data fabric expands on the architecture of a data warehouse. The data fabric includes building blocks such as data pipeline, data access, data lake, data store, data policy, ingestion framework, and data visualization.”
What are the key benefits of implementing these approaches?
Both data mesh and data fabric offer distinct benefits for organizations looking to improve their data management and analytics capabilities.
Here are the key benefits of implementing each approach:

You can also optimize resource utilization, reducing redundant data storage and processing tasks.
However, the centralized nature may lead to potential bottlenecks, slower responsiveness to domain-specific needs, dependency on a centralized team, and scalability challenges.
Centralized data management may also restrict innovation and experimentation. That is because teams may not have the autonomy to explore new technologies and approach best suited to their domain requirements.
Data mesh vs. data fabric: Five factors to consider
To decide between data mesh and data fabric, you should consider the following five factors:
- Organizational structure and culture
- Complexity and scale
- Technical maturity
- Data governance and security
- Speed of implementation and resource availability
Let’s see how each of these factors applies to the data mesh and the data fabric.
1. Organizational structure and culture
- Data mesh: Teams own and manage their data products. This is suitable for organizations that have cross-functional collaboration and autonomy.
- Data fabric: You set up a unified data layer across the organization. This is suitable for centralized IT and data management structures.
2. Complexity and scale
- Data mesh: It’s ideal for complex, large-scale data ecosystems where multiple domain teams must work independently and share data products.
- Data fabric: It’s ideal for organizations that want a unified data platform and can benefit from a single source of truth, regardless of the scale and complexity.
3. Technical maturity
- Data mesh: It requires a high degree of technical maturity, as it depends on domain teams having the necessary skills to manage their data products independently.
- Data fabric: It’s focused on building a seamless and unified data platform, which may be easier to manage for organizations with a less mature data engineering team.
4. Data governance and security
- Data mesh: It promotes data governance and security through ownership and accountability of domain teams. However, this can be challenging to enforce across multiple teams.
- Data fabric: It centralizes data governance and security, making it easier to enforce policies across the organization.
5. Speed of implementation and resource availability
- Data mesh: It could take longer to implement as it requires establishing data product ownership and infrastructure for each domain team.
- Data fabric: can be implemented more quickly if there is a strong centralized data engineering team in place.
Data mesh vs. data fabric: How does each approach fare when it comes to data governance and security?
While both approaches can address data security and governance, they do so in different ways.
Data mesh relies on domain teams taking ownership of their data products and adhering to organization-wide standards. Meanwhile, the data fabric centralizes security and governance practices, streamlining the implementation and enforcement of these standards.
Let’s explore the differences between data mesh vs. data fabric further.
Data mesh and data governance practices
The data mesh promotes a decentralized approach to data management, with domain teams being responsible for the security of their data products. This can lead to tailored security measures that are specific to the needs of each domain.
However, it also requires a high degree of collaboration and coordination across teams to maintain consistent security practices.
Data governance is enforced through the ownership and accountability of domain teams. Each team is responsible for the quality, lineage, and metadata of their data products, ensuring that the data is well-documented and adheres to the organization’s data standards.
So, a potential challenge with data governance in the mesh approach is maintaining consistent governance practices across different domain teams. This requires strong collaboration and communication, as well as the establishment of organization-wide data governance standards for all domains.
Data fabric and data governance practices
Data fabric centralizes data management, which can make it easier to enforce consistent security practices across the entire organization. A unified data layer allows for the implementation of standard security measures, such as encryption, access controls, and auditing, reducing the potential for inconsistencies in security practices.
Data fabric also centralizes data governance, making it simpler to implement and enforce organization-wide data governance policies. A unified data platform can facilitate consistent data quality, lineage, and metadata management, ensuring that all data adheres to established standards.
While this approach can make it easier to maintain data governance consistency, it requires a strong, centralized data engineering team to manage and enforce governance policies effectively.
Data mesh vs. data fabric: How does each approach fare when it comes to data quality?
Both data mesh and data fabric can address data quality challenges, but they do so with different strategies.
Data mesh emphasizes domain autonomy and tailored data quality measures, promoting accountability and encouraging teams to prioritize data quality within their specific domains.
Meanwhile, data fabric focuses on centralized data quality monitoring. Doing so allows for better control and management of data quality as it is managed in a centralized location.
Let’s explore the differences between data mesh vs. data fabric further.
Data mesh and data quality
Data mesh allows domain teams to implement data quality measures that are most relevant to their specific data types and use cases. This results in tailored data quality processes that address unique domain requirements.
Moreover, treating data as a product incentivizes domain teams to maintain high-quality data that meets the needs of their consumers.
However, a decentralized approach like the data mesh can lead to inconsistencies in data quality practices across different teams, which may impact the overall data quality within the organization.
Data fabric and data quality
Data fabric centralizes data management with a unified data platform, enabling the enforcement of organization-wide data quality policies and reducing the potential for inconsistencies in data quality practices.
However, a centralized approach can create bottlenecks or single points of failure, impacting data availability and performance, especially as the organization grows.
Choosing the best approach requires you to carefully weigh the pros and cons, along with your organization’s structure, culture, data quality requirements, anticipated team growth, and future data needs.
