Knowledge has grow to be a useful asset for companies, providing vital insights to drive strategic decision-making and operational optimization. Nonetheless, many firms as we speak nonetheless wrestle to successfully harness and use their information resulting from challenges akin to information silos, lack of discoverability, poor information high quality, and a scarcity of knowledge literacy and analytical capabilities to shortly entry and use information throughout the group. To handle these rising information administration challenges, AWS clients are utilizing Amazon DataZone, a knowledge administration service that makes it quick and easy to catalog, uncover, share, and govern information saved throughout AWS, on-premises, and third-party sources.
HEMA is a family Dutch retail model title since 1926, offering every day comfort merchandise utilizing distinctive design.

As we speak, that is powering each a part of the group, from the customer-favorite on-line cake customization function to democratizing information to drive enterprise perception.
This submit describes how HEMA used Amazon DataZone to construct their information mesh and allow streamlined information entry throughout a number of enterprise areas. It explains HEMA’s distinctive journey of deploying Amazon DataZone, the important thing challenges they overcame, and the transformative advantages they’ve realized since deployment in Could 2024. From establishing an enterprise-wide information stock and enhancing information discoverability, to enabling decentralized information sharing and governance, Amazon DataZone has been a sport changer for HEMA.
Knowledge panorama at HEMA
After shifting its whole information platform from on premises to the AWS Cloud, the wave of change introduced a singular alternative for the HEMA Knowledge & Cloud perform to take a position and commit in constructing a knowledge mesh.
HEMA has a bespoke enterprise structure, constructed across the idea of providers. These providers are particular person software program functionalities that fulfill a selected goal inside the firm. Every service is hosted in a devoted AWS account and is constructed and maintained by a product proprietor and a growth crew, as illustrated within the following determine.
HEMA runs over 400 providers, and 20 of them run extract, rework, and cargo (ETL) pipelines with devoted information sources, which produce and devour information property shared throughout the info mesh.
Knowledge administration in a knowledge mesh
Weeks after launch, HEMA’s information platform wasn’t the place the corporate wished it to be. Constructing an agile group that runs on dependable and streamlined processes was the first objective. Initially, the info inventories of various providers had been siloed inside remoted environments, making information discovery and sharing throughout providers handbook and time-consuming for all groups concerned.
Implementing sturdy information governance is difficult. In a knowledge mesh structure, this complexity is amplified by the group’s decentralized nature. On this context, HEMA concluded that information governance was not a nice-to-have, however had grow to be a foundational piece required to construct a wholesome information group.
Why HEMA chosen Amazon DataZone
By exploring the preview, HEMA noticed how Amazon DataZone lined all of the vital pillars of knowledge administration in a single resolution. It was clear how Amazon DataZone would deliver profit to each the technical groups in addition to the enterprise end-users. The technical group may reap the benefits of a strong programmatic resolution to handle the supply, accessibility, and high quality of the info property that make the enterprise information catalog. The enterprise end-users got a device to find information property produced inside the mesh and seamlessly self-serve on their information sharing wants.
Options akin to AI-generated metadata had been key to offering end-users with dependable and use case-driven explanations of what a sure information product may present and resolve, whereas the subscription function allowed them to start out utilizing a sure information asset inside their very own atmosphere in a matter of seconds, versus the prevailing prolonged and human-driven course of.
These causes, in addition to the self-service capabilities, resulted in HEMA’s resolution to undertake and roll out Amazon DataZone on the enterprise stage.
Answer overview
The HEMA information panorama is multifaceted, with numerous groups throughout the group utilizing a spread of applied sciences and methods, together with Databricks. To successfully govern this complicated information atmosphere, HEMA has adopted a knowledge mesh structure on AWS. This structure maintains a central intelligence platform (CIP) that allows the actions of each information producers and information shoppers by offering the mandatory platform and infrastructure. The general construction may be represented within the following determine.
Every service makes use of two AWS accounts, one for pre-production and one for manufacturing. This separation means adjustments may be examined totally earlier than being deployed to reside operations.
Amazon DataZone is the central piece on this structure. It helps HEMA centralize all information property throughout disparate information stacks right into a single catalog. It performs a pivotal function in bridging the hole and integrating completely different methods, akin to Databricks and native AWS providers. The mixing of Databricks Delta tables into Amazon DataZone is completed utilizing the AWS Glue Knowledge Catalog. Delta tables’ technical metadata is saved within the Knowledge Catalog, which is a local supply for creating property within the Amazon DataZone enterprise catalog. Entry management is enforced utilizing AWS Lake Formation, which manages fine-grained entry management and information sharing on information lake information. The next determine illustrates the info mesh structure.
The Amazon DataZone implementation follows the identical strategy as particular person providers: HEMA maintains two distinct area information catalogs: preprod-hema-data-catalog and prod-hema-data-catalog. These catalogs function the spine for information sharing throughout pre-production and manufacturing accounts, permitting versatile entry to information property primarily based on the atmosphere’s wants.
The prod-hema-data-catalog is the production-grade catalog that helps information sharing throughout manufacturing providers and, in some instances, pre-production providers. This catalog solely facilitates the manufacturing of knowledge property from manufacturing providers (disallows publishing of property belonging to pre-production providers) and permits pre-production providers to entry production-grade information. The next diagram illustrates the structure of each accounts.
To ascertain isolation between providers within the information mesh, a challenge is devoted to a singular service account. The atmosphere profiles and environments are configured to be explicitly used solely by the service. This Amazon DataZone configuration is managed centrally by the core crew utilizing AWS CloudFormation. After initiatives are created and configured by the central crew, challenge groups have entry to self-service capabilities to create their very own environments in line with their wants.
The next diagram illustrates the complete workflow for onboarding HEMA service groups in Amazon DataZone.
The workflow consists of the next steps:
- A service crew (both a knowledge producer or a knowledge client) initiates a request to the core information platform crew to allow information sharing for his or her service accounts. This request is usually made when a service crew has a use case the place they should both publish information to the catalog (for different groups to devour) or entry information that one other crew has printed.
- After the request is obtained, the core information platform crew assesses the necessities and initiates the creation of initiatives and environments in Amazon DataZone. That is finished utilizing AWS CloudFormation and a steady integration and supply (CI/CD) pipeline. The core information platform crew makes certain that the suitable AWS account (pre-production or manufacturing) is linked to the atmosphere inside the challenge within the respective catalogs.
- After the initiatives and environments are arrange, service groups can use Amazon DataZone options to provide and devour information property:
- Producers (for instance, Service A) can publish their information property to the Knowledge Catalog and approve or reject subscription requests.
- Customers (for instance, Service B) can search and entry these printed information property utilizing the Amazon DataZone catalog and request information entry by way of subscription requests.
In a decentralized information mesh atmosphere, there’s a threat of service groups creating sources in service accounts they aren’t approved to handle, which can result in governance points and information mismanagement. To handle this problem, HEMA adopted two ideas:
- Amazon DataZone challenge construction – Every challenge comprises sources which are solely managed by the service crew (challenge members) accountable for it. Every service crew’s challenge offers a transparent boundary for the sources they handle.
- Atmosphere isolation – The core groups implement governance insurance policies within the Amazon DataZone configuration, permitting groups to solely deploy sources inside their very own environments.
Adoption plan: Technique
In HEMA’s information mesh, the catalog have to be inbuilt collaboration with all of the providers that produce information, so the important thing for the central information governance crew was ideating an adoption plan that may add worth to those groups, slightly than disrupting the supply of their initiatives. With that in thoughts, HEMA’s adoption technique was designed on three core ideas:
- Launch it – Don’t wait till you may ship to manufacturing a full-scale service that covers each single function out there. As a substitute, outline an MVP that solves essentially the most vital want for the enterprise and make it out there for the enterprise as quickly as you may.
- Show worth – HEMA’s information crew ran a number of inside seminars, and devoted shows with every of the concerned groups to showcase how Amazon DataZone would simplify their information sharing wants. Don’t inform them they have to make investments time to study and begin utilizing a brand new service, however slightly allow them to get drawn in by the brand new benefits of the brand new performance and stimulate self-adoption.
- Be there – This connects with what HEMA as an organization stands for. Be near the groups once they want assist throughout the adoption stage, like HEMA is near their clients each time they want a brand new product for his or her lives. Create area for Q&A and develop a collaborative expertise for everybody of their adoption curve.
Adoption plan: Motion factors
Whereas deploying the adoption plan for a decentralized information market utilizing Amazon DataZone, HEMA adopted a “begin small, fine-tune, and iterate” strategy. In observe, this meant that the Knowledge & Cloud crew began working with one enterprise unit, increasing then to a number of enterprise items, whereas specializing in one single function: information asset subscription. To extend curiosity and adoption, this course of was launched for the core information property that had been extra used within the firm.
After this a part of the method was nicely understood and embraced by everybody, the subsequent step was to start out supporting the info pipeline adaptation work wanted for every enterprise unit.
Lastly, when all groups had been onboarded and accustomed to the subscription function, HEMA moved to introduce the enterprise items to the second vital function: information publishing. In abstract, HEMA launched new options and allowed the domains to choose up the implementation at their most popular tempo earlier than shifting onto the subsequent one.
When adoption was at a degree the place all core information property had been being consumed by way of the Amazon DataZone catalog, the Lake Formation useful resource hyperlinks used beforehand to share information throughout accounts had been decommissioned, and on the similar time the Knowledge & Cloud crew interrupted their responsibility to share information between enterprise items, stimulating the peer-to-peer information sharing observe, the place groups can instantly speak to one another with out having to contain a 3rd celebration.
Outcomes
The recognition of Amazon DataZone throughout the enterprise ramped up shortly, and all of the concerned enterprise items began utilizing the service every day to self-serve their wants. The existence of a central information catalog enabled groups to seamlessly search, uncover, share, and subscribe to information property produced inside the enterprise. Only some months after launching the service, HEMA noticed gorgeous statistics:
- Over 200 information property printed to the catalog
- Over 180 lively subscriptions
- Over 100 lively customers month-to-month
- Over 20 enterprise items (providers) onboarded
- Knowledge sharing common turnaround time lower from 4 working days to few seconds, with out the assist of some other crew
Moreover, they noticed huge advantages that may’t be represented by statistics. Above all, the power to autonomously uncover information produced by different groups is enabling a sequence of recent use instances for the enterprise, which weren’t even seen to them earlier as a result of lack of information and visibility on what others had been producing. For instance, the info science crew shortly developed a brand new predictive mannequin for gross sales by reusing information already out there in Amazon DataZone, as a substitute of rebuilding it from scratch. That is leading to an energized information group, which may collaborate and contribute to shaping the way forward for HEMA’s information operations.
Conclusion
At HEMA, Amazon DataZone made information governance a actuality, and so the corporate desires to implement new options in shut collaboration with AWS, whereas persevering with to work on the rollout of things which are already in HEMA’s roadmap. The crew is constantly creating the service, launching a sequence of recent options that can proceed to enhance the info operations:
- Knowledge high quality scores – This function helps information producers monitor and optimize their information property, whereas shoppers can see upfront the nuances of a sure asset that they may be utilizing or want to use inside their ETL pipelines
- Knowledge lineage – This function permits shoppers and the central governance crew to hint information sources, transformation phases, and observe cross-organizational utilization of knowledge property
- Superb-grained entry management – This function permits producers to be in full management of what they share with different items, ensuring that solely the related items of a knowledge asset are shared with the consuming groups
The long-term imaginative and prescient of HEMA is obvious: Amazon DataZone is about to grow to be the central resolution for information sharing and information cataloging throughout the enterprise. Though as of as we speak, Amazon DataZone is targeted on supporting the groups working ETL pipelines, the objective is to increase the service to all of the enterprise groups that work with information, with the final word objective of streamlining their every day operations. Knowledge is among the most respected sources an organization has, and HEMA is set to democratize its function by constructing an environment friendly information group, who depends on essentially the most superior information governance resolution in the marketplace.
