Man and woman using the four principles of data mesh.

A relatively new term in the world of data management, data mesh refers to the process of creating a single, unified view of all enterprise data. This process can happen in several ways, giving business users easy access to the data they require for decision-making. Several principles guide data mesh design and implementation. This article will discuss the principles of data mesh and how they can help your business get the most out of its data.

What Is Data Mesh and What Are Its Benefits?

Data mesh architecture enables organizations to build a decentralized data infrastructure. It provides a way to distribute data across multiple nodes or "data meshes" to increase flexibility, scalability, and security. Additionally, data mesh can help reduce the risk of data silos or data lakes by providing a more unified view of an organization's data.

There are many benefits to using a data mesh, including:

  • Increased flexibility and scalability: Data mesh provides a way to distribute data across multiple nodes, increasing flexibility and scalability. A solution that can quickly scale is essential for growing organizations with large amounts of data.
  • Improved security: Data mesh helps improve security by providing a way to segment data and control access. This feature can be especially important for sensitive data.
  • Reduced costs: Data mesh helps reduce costs by eliminating the need for additional expensive hardware or software solutions.
  • Increased availability and data access: Data mesh can increase availability through its distributed data solution and direct path to data. This is important for organizations needing high data availability, such as real-time applications or time-sensitive data.
  • Transparency and governance: Data mesh offers transparency and governance by giving organizations visibility into how data is used. This visibility helps organizations comply with regulations or company policies.

The Four Principles of Data Mesh

Data mesh is built on four fundamental principles.

1. Domain-Oriented Decentralized Data Ownership & Architecture

A domain-oriented data mesh comprises many small, independent data services that own and manage a slice of the total data. These services are deployed across a decentralized architecture, often following a microservices pattern.

The key benefits of business domain-driven design are:

  • It allows for true decentralized data ownership, where each domain team can control its domain data without depending on other groups.
  • It leads to more maintainable codebases and fewer dependencies between services.
  • It enables an organization to scale its data infrastructure horizontally by adding more instances of each service.

The key benefits of a decentralized data architecture are:

  • It allows for greater flexibility in how teams deploy and manage their services.
  • It makes it easier to integrate new services into the data mesh.
  • It reduces the risk of a single point of failure.

2. Data as a Product

Data is treated as a product in a data mesh, meaning that data is produced, consumed, and managed as a first-class entity in the organization. To deliver an efficient workflow to end users, data product owners must design, build, and operate data pipeline products that are easy to use and tailored to the actual needs of data consumers.

The products must be:

  • Easy to use: Data products must be designed for ease of use. This includes everything from the user interface to the documentation.
  • Tailored to users: Data products must be tailored to the specific needs of the users. One size does not fit all when it comes to data products.
  • Operationalized: Data products must be operationalized so that end users can easily consume them. Having operational data means that data products are well-managed and always available when needed.

The benefits of data product thinking are:

  • It leads to better data quality since teams are responsible for the quality of the data they produce.
  • It encourages teams to think about how others will use their data, leading to more usable data products.
  • It creates a feedback loop between users and producers of data, leading to continuous improvement.

3. Self-Serve Data Infrastructure as a Platform

A data mesh enables teams to self-serve their data infrastructure needs, while groups can provision and manage their data services without depending on centralized IT operations. Some concerns that IT traditionally addresses, such as data security and compliance, can be delegated to the teams that own the datasets.

The benefits of self-serve data infrastructure are:

  • It decreases the time to value for new data projects: Teams can quickly provision and deploy new data-driven services without waiting for IT approval.
  • It reduces the dependencies between teams: Communication between teams can be a significant bottleneck in data projects. Self-serve data platform infrastructure reduces the need for coordination between teams.
  • It leads to more agile data infrastructure: There are often times when data must be iterated on quickly to meet the needs of the business. Self-serve data infrastructure enables teams to quickly and easily change their data services.

4. Federated Computational Governance

Governance in a data mesh is federated, meaning it is distributed among the various teams that own data. This distribution leads to better decision-making about how data should be used and managed since the groups closest to the data are making decisions about it. In the past, centralized IT operations teams often made decisions about data, leading to slow decision-making and immutable data infrastructure.

The benefits of federated computational data governance are:

  • It encourages experimentation: Teams can experiment with new ways of using and managing data without fear of breaking existing processes.
  • It reduces the risk of changes: Changes to the data infrastructure are isolated to the teams that own the data, reducing the risk of affecting other groups.
  • It allows for more automation: Teams can automate their data management processes without affecting other teams.

The Challenges of Data Mesh and How to Overcome Them

Data mesh is not without its challenges. Here are some of the challenges you may encounter during data mesh implementation and how to overcome them:

  • Lack of standardization:One of the challenges of data mesh is that there is no one-size-fits-all solution. Finding the right tools and technologies for your organization can be challenging. To overcome this challenge, it's essential to start small and scale up as you learn more about data mesh.
  • Dependencies on other teams: Data mesh can depend on other teams at the beginning, such as IT or Ops, to succeed. You want to assign data team leads for each mesh pillar and work with them to ensure successful implementation.
  • Lack of training and resources: Since data mesh can be complex, you must set up the proper training and resources. You might also consider working with a data mesh consultant or provider that can help you get started, or you could create an internal training program for employees.

How to Evaluate the Success of Data Mesh

A few key indicators and metrics can help you evaluate the success of data mesh:

  • Data quality:One of the benefits of data mesh is improved data quality. To measure this indicator, you can track the number of errors in data and the time it takes to fix them.
  • Time to value: Data mesh should reduce the time it takes to get new data products and features to the market. Here, you can track the time from when a project starts to when it launches.
  • Dependencies: Data mesh should reduce dependencies between teams. When measuring this indicator, track the number of communication channels between teams and the time spent waiting for other teams' input.
  • User satisfaction: Data mesh is designed to improve the experience of the people who use data products. For this one, you can track user satisfaction scores and the number of support tickets related to data products.

How DreamFactory Can Help

DreamFactory is a low-code management platform that can be used to build and deploy APIs.
