Data Fabric vs Data Mesh Comparison

Overview

Data fabric and data mesh are two architectural patterns for managing data in complex and distributed environments. While they both aim to democratize access to enterprise data by users and subject matter experts (SMEs), they take a different approach to certain elements like data governance and ownership.

Data fabric and data mesh are the evolution of data lakes and operational data stores as they focus on providing a unified view of the data, offering more agility and scalability as well as better performance. This is typically done through the use of metadata to build a semantic layer for data microservices. The semantic layer represents a logical map of all data assets—think of it as a treasure map of your enterprise knowledge that enables business users to find the information they need in an intuitive way.

For example, if customer data was stored across different locations like your CRM, marketing website, invoicing and procurement applications, and you needed a comprehensive picture of it, a semantic layer within a data fabric would allow you to pull the information you need in a cohesive view, making connections between data that didn’t exist before.

The semantic layer removes obstacles in the physical (infrastructure) layer and brings all content into a data catalog. This unifies different business vocabularies that can be easily kept up to date with business changes to the data, preserving lineage and provenance.

What Is Data Fabric?

A data fabric is a data-centric architectural approach designed to simplify data management, data governance and data retrieval across a diverse array of data silos and systems. Its purpose is to provide unified and seamless access, sharing and governance of data, regardless of where it resides or how it is stored.

A data fabric facilitates data integration, orchestration and processing by creating a consistent and coherent data layer in support of operational, analytical and AI workloads.

Data fabrics also enrich data with metadata to enable the discovery and interpretation of data based on meaning as well as active context based on state, use and audience. This helps users and AI systems navigate, sift through and understand the data they are leveraging for insights essential to their roles.

For example, some staff are overwhelmed by the amount of data they are exposed to, where lots of it is irrelevant. Enveloping data assets and information about them with annotations and delivering them in a single view gives users context about whether the information is accurate, fresh, newly updated or changed by someone. This process also makes it clear what system the data is coming from. Data fabrics serve as a good foundation for coupling data with metadata to deliver that consolidated view.

In data fabrics, the following foundational activities converge in a meaningful, synchronized way to enhance business processes with a connected data ecosystem:

  • Data Integration: Connecting various data sources, including structured and unstructured data, to enable comprehensive data access and analysis.
  • Data Orchestration: Automating the movement and transformation of data across different environments so it is available where and when needed.
  • Metadata Management: Enhancing data discoverability, lineage and quality by maintaining detailed metadata about data assets.
  • Data Governance: Facilitating compliance, data security and proper management of data through robust policies and practices.

When data fabrics are implemented successfully, organizations can achieve greater agility and efficiency in their data operations, improve decision-making and support artificial intelligence initiatives. Data fabrics provide a consistent and reliable data foundation and overcome the challenges posed by traditional application-centric approaches to data management, including deep data silos and complexity. This leads to better data utilization and business outcomes.

Data Fabric Components and Architecture

A data fabric is a prescriptive approach to architecting and connecting your data ecosystem and as such, its implementations can vary. By industry definition, data fabric is comprised of many elements, including a unified data layer, data workflows, search engine, data catalog, knowledge graph and data service APIs. These components can be selected and combined depending on what makes sense for your enterprise and its data types, systems and governance maturity.

Let’s take a look at some of the key components of a data fabric:

  • Unified Data and Metadata Layer
  • Semantic Layer with Data Catalog
  • Abstracted Data Access and Unified Data Retrieval
  • Centralized Security and Governance

What Is Data Mesh?

A data mesh is another modern approach to managing and utilizing data within an organization. It shifts slightly from the traditional centralized data architecture to a more decentralized, domain-oriented structure. This allows for data produced and used within a specific domain or organizational department to be packaged as “products” that are more easily and independently managed by the same people who know it best, preserving valuable expertise and context.

Data meshes delegate data governance to the data owners, promoting better information stewardship, accountability and transparency within the business. This is a key difference between data meshes and data fabrics, where governance is managed more centrally.

The data mesh concept was introduced by Zhamak Dehghani, a thought leader in data architecture. It aims to address several challenges commonly faced in traditional data systems, such as scalability issues, bottlenecks from centralized data teams and difficulties in maintaining data quality, consistency and relevance across diverse business areas.

Data Mesh Components and Architecture

The key principles and concepts of a data mesh are:

  • Domain-Oriented Decentralization: In a data mesh, data is organized around business domains rather than centralized in a single repository. Each domain, such as marketing, finance or sales, is responsible for its own data, treating it as a product. This helps distribute ownership and accountability to those who have the most context about the data.
  • Data as a Product: Each domain team treats their data as a product, with clear ownership, documentation, quality standards and discoverability. This approach leads to data that is reliable, easy to understand and readily available to other teams.
  • Self-Serve Data Infrastructure: To empower domain teams to manage their data products, a data mesh provides a self-serve data infrastructure platform. This platform offers tools and capabilities to ingest, store, process and share data without heavy reliance on a central data team.
  • Federated Governance: While domains are autonomous, there is still a need for overarching governance to support interoperability, security and compliance. Federated computational governance provides a framework that enforces global policies while allowing domains to implement local rules that best fit their needs.

Benefits of Data Mesh

By adopting a data mesh, organizations can achieve greater agility, improve data quality and make data more accessible and usable for analytics and decision-making across the enterprise.

  • Scalability: Data mesh architecture scales more efficiently as it decentralizes data ownership and management. Each domain or team handles its own data, reducing bottlenecks and the burden on central data teams and allowing organizations to scale their data infrastructure more effectively.
  • Improved Data Quality: With data mesh, data ownership is distributed to domain-specific teams who are closest to the data and understand it best. This can lead to better data quality, as those who produce and use the data are responsible for maintaining and improving it.
  • Faster Time to Market: Decentralizing data management allows domain teams to work independently and innovate faster. They can make quicker decisions without waiting for a centralized data team to implement changes, leading to faster development cycles and quicker delivery of data-driven insights and products.
  • Enhanced Agility: Data mesh promotes agility by allowing different teams to adopt and implement the tools and technologies that best fit their needs. This flexibility enables teams to respond more swiftly to changes in the market or business requirements.
  • Reduced Data Silos: By promoting a federated governance model and standardized data sharing practices, data mesh helps break down data silos. Data products are made available across the organization, facilitating easier access and integration of data from different domains.
  • Improved Data Governance: Data mesh includes principles for federated computational governance, enabling consistent security, compliance, and quality standards across domains. This approach helps maintain control and oversight without stifling innovation and agility.
  • Empowered Teams: Teams gain greater autonomy and responsibility over their data, fostering a sense of ownership and accountability. This empowerment can lead to increased motivation and innovation as teams have more control over their data and its applications.
  • Better Alignment with Business Goals: Since data is managed within domains that align closely with business functions, there is better alignment between data initiatives and business objectives so data strategies directly support business outcomes.
  • Enhanced Collaboration: Data mesh encourages collaboration across domains through shared data products and common standards. Teams can easily share and leverage each other’s data, leading to more comprehensive insights and collaborative problem-solving.

By addressing the limitations of traditional centralized data architectures, a data mesh approach enables organizations to handle data more efficiently and effectively, driving better business outcomes and fostering innovation.

Can Data Fabric and Data Mesh Work Together?

Both architectural patterns come with their drawbacks, making it challenging for organizations to stick to definitions when it comes to their implementation. Data fabric’s centralized approach poses challenges to effectively applying governance rules. Data mesh’s decentralized approach, on the other hand, makes distributed querying of enterprise data extremely hard. Additionally, federated governance in a data mesh can lead to lack of standardization or inconsistencies in data quality practices across different domains, which may impact the interoperability of enterprise data and its ability to be leveraged within the organization for intelligence or machine learning purposes.

A composable, mix-and-match approach works best in most scenarios. It’s imperative to remember the business objective of evolving an enterprise architecture is to establish a central point of access. In many cases, a hybrid approach between centralized data repository, integration and security combined with federated governance would work best.

In fact, Gartner predicted that, by 2027, 30% of enterprises will use data ecosystems enhanced with elements of data fabric supporting composable application architecture to achieve a significant competitive advantage.

What Data Architecture Fits Your Use Case?

Depending on your use case and business needs, you could choose to go forward with either architectural pattern. There are a few rules of thumb to keep in mind.

Generally, both data meshes and data fabrics are advanced data architectures that require a high level of data governance and metadata maturity practices to be successful. If you are only looking to run advanced analytics and business intelligence to run the business, a data store may be the perfect fit without the extra work, workforce education and cost that implementing a modern data architecture requires. On the other hand, if you are dealing with a combination of legacy systems, getting new systems added and no authoritative system for analytics, it’s time to consider modernizing your architecture and infrastructure to meet today’s business needs.
