There has been a significant rise in data production in recent years, measured by the “Three V’s” of data: Volume, Variety and Velocity. As data continues to expand, organisations face mounting pressure to maximise its potential and gain better insights by leveraging it more efficiently and effectively.
Historically, organisations worldwide have relied on traditional data analysis methods. However, as businesses continue to require expedited analysis, it is becoming evident that traditional approaches have limitations. Therefore, a more efficient and streamlined data analysis approach is necessary. In this case, data mesh comes into play as a potential solution. Data mesh offers organisations an alternative to traditional data lakes and warehouses; a simpler, faster, and more effective means of meeting the real-time demands of data analysis.
Data Mesh Fundamentals Course
Organisations have historically used records to reveal trends and improvement opportunities. However, in this digital era, the conventional method of constructing and delivering reports later in the day is now obsolete. Data mesh is a contemporary analytics strategy that considers the necessity of immediate insights. Given the current business climate, real-time analytics are critical for all teams and individuals to improve performance.
With the present data terrain, companies are increasingly using data lakes as the preferred method of data storage. A data lake is a comprehensive repository that can store all types of data. However, centralised systems are not always the most efficient option. A data mesh represents a newer approach that enables organisations to segment their data into several distinct domains, each managed by its administrators. This approach offers a more detailed approach to data storage and management, leading to improved security and efficiency.
Data mesh is founded on four primary pillars:
- Domain Control
- Data as a Commodity
- Self-Serve Data
- Federated Computational Governance for Organisations
The key objective of this approach is to ensure that data is managed by those equipped to derive the greatest benefit from it. The question that now arises is who should hold the authority to access specific information.
Zhamak Dehghani‘s 2020 book, “Data Mesh Principles and Logical Architecture,” presents a novel method for breaking down a data set. The Data Mesh strategy utilises the boundaries between distinct functional units as the primary basis of segmentation, which is especially relevant in modern businesses that are organised into a variety of specialisations. Examples of these units include departments such as Order, Shipping, Inventory, Billing, and Customer Service.
Specialised “data teams” within each division would be responsible for ensuring that the generated data adheres to the company’s standards. These teams would be made up of experts in their respective fields. By utilising standardised nomenclature, these “data teams” can access high-quality, structured data from various sources.
Data as a Commodity
The data shared within your domain should be viewed as high-quality commodities, with other “data teams” in your organisation representing your internal clients.
Zhamak Dehghani suggests in an article that implementing a “data as a product” philosophy can help address data quality and silo issues. Gartner refers to the data that companies collect, process, and store as part of their regular operations, but which is not often used for other purposes, as “black data.”
The advent of “data teams” has given rise to a new position, the domain data product owner, responsible for ensuring that other domain teams receive their data in an optimal format. This person will be in charge of standardising and properly packaging data, as decentralisation and resulting local autonomy can lead to data silos and significant data quality concerns. It is therefore critical to proactively prevent data chauvinism.
Autonomous Data Hubs
To guarantee the success of any project, it is crucial to have access to accurate and timely information. When beginning a new project, it is recommended to include historical data in the database and continually update the information to reflect any changes or events that occur. This will ensure that the project is founded on the most current and pertinent data available.
Usually, you will receive a Comma Separated Values (CSV) file, which has its own set of challenges. It may be challenging to generate a matching schema if the novel event streams and snapshot files have distinct schemas or dissimilar field names. Additionally, this process is seldom automated.
This concept aims to tackle the challenge of delivering historical and real-time data on demand across all databases within an organisation. To ensure the implementation’s success, a sophisticated, centralized, and autonomous infrastructure must be put in place.
Federated Computational Governance for Organizations
Setting up global naming conventions is crucial for enabling successful communication and collaboration among numerous autonomous data teams that specialize in various research fields. Adherence to such standards will facilitate seamless exchange of information between these groups, thus boosting overall work productivity.
In her work, Zhamak provides a clear explanation of federated computational governance, which involves utilising different data products to extract valuable insights, datasets, and machine intelligence. This system requires a governance architecture that enables decentralisation, domain self-sovereignty, interoperability through global standards, dynamic topology, and automated execution of decisions. These features allow the platform to operate at scale by performing graph, set, or other operations, resulting in higher-order datasets, insights, or machine intelligence, thereby creating a data mesh. This decentralised and automated governance system is also known as federated computational governance.
A unified set of international standards must be established by a consortium consisting of data product owners and data platform product owners, providing regulations that apply to all data products and their associated user interfaces, allowing them to exercise their autonomy and decision-making authority in their respective fields.
Data Mesh is an innovative methodology for managing data that aims to supersede the conventional centralised approach for processing and sharing data between departments within an organisation, lowering overhead costs while maximizing efficiency. Data Mesh offers an alternative solution designed to streamline the process, enabling effective and efficient data transfer and exchange.

Despite the encouraging possibilities, extensive efforts from many individuals are still required for the successful implementation of data mesh. As data mesh is still in its early stages, it is likely to take some time before it can replace the present data architecture frameworks.
