Paying ahead what you’ve discovered to the subsequent knowledge chief is the true spirit of the Atlan neighborhood! In order that they’re right here to share their hard-earned perspective on an evolving market, what makes up their fashionable knowledge stack, modern use instances for metadata, and extra.
On this installment of the collection, we meet Surj Rangi, Enterprise Cloud Information Architect, Piyush Dhir, Senior Technical Lead, and Danni Garcia, Product Supervisor, at REA Group, the operator of main residential and business property web sites, mortgage brokering providers, and extra. Surj, Piyush, and Danni share REA’s evolving knowledge stack, their data-driven ambitions, and the factors and course of behind their selection of Atlan.
This interview has been edited for brevity and readability.
Might you inform us a bit about yourselves, your backgrounds, and what drew you to Information & Analytics?
Surj Rangi:
I’m Surj Rangi, Architect in Information Providers, and I’ve been at REA for 2 years now. I graduated in IT from the UK, then labored in plenty of consultancy corporations in Information and Analytics and developed a robust background in cloud platforms and knowledge structure. I migrated to Australia about seven years in the past, with twenty years of expertise in knowledge throughout numerous industries together with Media, Telecommunications, Finance, E-commerce and Banking.
I joined REA and was very eager on the position that I used to be provided and the staff I used to be coming into. What actually enticed me was working with an organization that had a startup mentality, and have been excited to push and ship outcomes. Beforehand, I’ve labored with giant banks the place there’s a whole lot of forms and issues take time, and I used to be excited to see how issues work at a spot like REA.
Piyush Dhir:
I’m a Senior Technical Lead at REA. My journey goes again to college once I was ending my Bachelors in Software program Engineering and wanted to decide about what I needed to do subsequent.
I began as an Android developer again when it appeared like everyone’s subsequent factor was “What’s going to be my subsequent Android mission?” Once I was doing that, I got here throughout SQL Server, studying how it’s a must to do operational modeling once you’re creating one thing like a front-end utility. That’s how I made my first step into knowledge. Since then, I’ve been working throughout plenty of totally different varieties of information groups.
My first knowledge staff was a Information Administration staff for a public firm in Australia. They have been ranging from zero, constructing an entire greenfield ecosystem for his or her knowledge utilizing the SAP merchandise. I spent about 5 years in that world, then moved into a whole lot of small firms and massive firms. I did a little bit of consulting, I labored for a financial institution within the center, after which lastly ended up at REA.
Once I first joined an information staff again in 2012, what actually stood out to me on the time was that knowledge was mentioned to be “the brand new oil”, and that Information & Analytics have been going to be the subsequent massive factor. Again then, some folks began doing Machine Studying and taking part in round with R Studio, nevertheless it was by no means the “bread and butter” of any firm, simply a type of “north star” type of initiatives.
All of a sudden, now 10 years down the road, it’s develop into not solely the “bread and butter” of the corporate, nevertheless it’s a chance for monetization for lots of them, too. It’s good to see that transition occurring, and it’s been fascinating to look at.
Danni Garcia:
I’m a Product Supervisor in Information Providers with a selected background in Information research. I haven’t at all times been in Product. I’ve labored within the know-how business for nearly a decade now throughout many alternative areas and roles in each giant and small organizations, however I began out as a Information Analyst.
Would you thoughts describing REA, and the way your knowledge staff helps the group?
Surj:
I believe it’s good to know that REA began in a storage in Australia within the early-to-mid ’90s, and since then the corporate has grown and scaled enormously throughout the globe. REA has a presence not solely in Australia, however Asia too and has robust ties with NewsCorp. We began by itemizing residential properties, and it’s grown from there to business properties and land, as effectively. We’ve additionally performed a whole lot of mergers and acquisitions. For instance in Australia, we’ve purchased a agency referred to as Mortgage Selection that permits REA to be positioned not solely to promote listings, publications, and supply insights into property into the business in Australia, but in addition present mortgage dealer providers.
So if you wish to promote your property, REA offers the entire bundle. You may promote your property, and for those who want financing, we may also help you financial your subsequent funding.
We’ve gone by means of an extended journey, and have had a Information Providers staff for an extended time frame. Every little thing was decentralized, then it was centralized. Now it’s a little bit of a hybrid, the place we have now a centralized knowledge staff constructing out the centralized knowledge platform with key capabilities for use throughout the group, with decentralized knowledge possession. We try to align with a Information Mesh strategy by way of how we construct out our platform capabilities and adoption of “knowledge as a product” throughout the group.
We’re multi-cloud, each AWS and GCP, which brings its personal challenges, and we do the whole lot from ingestion of information, event-driven structure to machine studying. We’re constructing knowledge belongings to share with exterior firms within the type of an information market.
Danni:
Information Providers exists to help all the inside strains of companies throughout our group. We’re not an operational staff, however a foundational one, that builds knowledge merchandise and capabilities to assist help groups to allow them to efficiently leverage knowledge for his or her merchandise. Our mission is to make it straightforward to grasp, shield and leverage REA knowledge.
Piyush:
I’ll add that over the past couple of years, REA has predominantly seen themselves as a listings enterprise. It’s nonetheless a listings enterprise, offering the very best listings data doable out to prospects and shoppers. However what’s occurred is that this wealthy knowledge evolution helps our enterprise develop into data-driven. A number of the knowledge metrics you see on the REA web site and cellular utility are principally derived from the work that the group has put in to develop our Information & Analytics and ML observe to drive higher resolution making.
We’ve got a whole lot of helpful knowledge. There are a whole lot of initiatives happening now to develop the utilization of information, and over the subsequent two years, we are going to develop our panorama and derive even higher outcomes for our prospects and shoppers. to grasp, leverage, then showcase knowledge to our prospects and their prospects.
What does your knowledge stack appear to be?
Danni:
We’ve got a real-time ingestion platform referred to as Hydro utilizing MSK, which is a custom-built streaming platform. Then we have now our batch platform, which ingests batch knowledge utilizing Breeze, constructed on Airflow. Our knowledge lake resolution is BigQuery.
Piyush:
We have a look at ourselves as a poly-cloud firm, utilizing each AWS and Google Cloud Platform, in the meanwhile.
From an AWS perspective, we have now most of our infrastructure workloads operating there. We’ve got EC2 situations and RDS operating there. We’ve got our personal VPC. We’ve got a number of load balancers.
From a Information and Analytics perspective, nearly all of our workloads are in GCP. We’re at the moment utilizing BigQuery as an information lake idea, and that’s the place most of our workloads run. We use SageMaker for ML, and there’s some groups which are experimenting with BigQuery ML on the GCP facet, as effectively. We even have a self-managed Airflow occasion, in order that’s our knowledge platform.
We’re at the moment within the technique of establishing our personal event-driven structure framework utilizing Kafka, which is on AWS MSK.
Aside from that, our Tableau entrance finish is used for reporting, so we have now each the Tableau desktop and the server model, in the meanwhile.
Why seek for an Energetic Metadata Administration resolution? What was lacking?
Surj:
We’ve got an present open-source knowledge catalog that we have now been utilizing for a number of years now. Adoption has not been nice. As we’ve scaled and grown, we realized that we wanted one thing that’s extra related for the fashionable knowledge stack, which is the path that we’re going in direction of.
There’s additionally a stronger push in our business towards higher safety of information. We retailer a whole lot of personally identifiable knowledge throughout the enterprise, and a few of our key methods we have now in Information Providers are that we need to first perceive the info, shield it, then leverage it. We wish to have the ability to catalog our knowledge, and perceive how dispersed it’s throughout our warehouses, numerous platforms, in batches, and streams.
We’ve got a whole lot of knowledge, e.g. we’ve bought over two petabytes of information in GCP BigQuery alone. We wish to have the ability to perceive what knowledge is, the place it’s put collectively, and apply extra rigor to it. We’ve got good frameworks internally by way of governance, processes, and insurance policies, however we need to have the fitting tech stack to assist us use this knowledge.
Danni:
There have been some technical limitations, as our earlier knowledge catalog may solely help BigQuery, however we actually needed to help the path of the enterprise by way of scale and the way it will align extra broadly with our Information Imaginative and prescient and Technique.
Our technique needs to implement Information Mesh and ‘Information as a Product’ mindset throughout the group. Each staff owns knowledge, they leverage it they usually have a accountability to handle it with governance frameworks.
So, as a way to embed Information Governance practices and this cultural shift, we wanted a device to help the frameworks, metadata technique, and tagging technique. We additionally wanted an answer to centralize all our Information Belongings so we may have visibility of the place knowledge is and the way it’s being categorised which helps our Privateness initiatives.
We’re nonetheless on a change journey at REA, which could be very thrilling. A brand new knowledge catalog was an actual alternative to push ourselves additional into that transformation with a brand new Information Governance framework.
How did your analysis course of work? Did something stand out?
Surj:
We did some market analysis, chatting with Gartner and reviewing accessible tooling throughout the business. We may have clearly stored utilizing our present Information Catalog, however we needed to judge a large spectrum of instruments together with Atlan, Alation, and Open Metadata, to cowl Open Supply vs. Vendor managed.
We felt Atlan match the factors of a contemporary knowledge stack, offering us the capabilities we want, comparable to self-service tooling, an open API, and integrations to quite a lot of know-how stacks which have been all essential to us.
We had an overwhelmingly good expertise partaking with Atlan, particularly with the Skilled Providers staff. The arrogance that they gave us within the tooling after we went by means of our use instances drove a sense of robust alignment between REA and Atlan.
Piyush:
We did a three-phase analysis course of. Initially we went out to the market, did a few of our personal analysis, making an attempt to grasp which firms may match our use instances.
As soon as we did that, we went again and checked out totally different features comparable to pricing and used that as a filtering mechanism. We additionally appeared on the future roadmap of these firms to determine the place every firm could be going, which was our second filtering course of. After we have been performed choosing our choices, we had to determine which one would go well with us greatest.
That’s after we did a lightweight proof of worth the place we created high-level analysis standards the place everyone concerned may rating totally different capabilities from 1-10. The staff included a supply supervisor, a product supervisor, an architect, and builders, simply to get a holistic view of the expertise everyone could be getting out of the device. After that scoring, we made a light-weight suggestion and offered it to our executives.
A few of what we have been within the analysis standards have been issues like understanding what knowledge sources we may combine to, what safety appeared like, and ideas like extensibility so we might be versatile sufficient to increase the catalog programmatically or through API. As a result of we have now our knowledge platform operating on Airflow, we additionally needed to grasp how effectively every choice labored with that.
Then we additionally checked out roadmaps and requested ourselves what would possibly occur sooner or later, and if one thing like Atlan’s funding in AI is one thing we must be trying into, and different future enhancements Atlan or different distributors may present. We have been making an attempt to get an understanding of the subsequent two or three years, as a result of if we’re investing, we’re investing with a long-term perspective.
Surj:
In case you have a look at the time period “Information Catalog”, it’s been round for a really very long time. I’ve been working over twenty years, and I’ve used knowledge catalogs for a very long time, however the evolution has been vital.
When Piyush, Danni and I have been distributors, that’s one thing we have been desirous about. Would you like a conventional knowledge catalog, which we’ve most likely seen in banks which have a robust, ruled, centralized physique, or would you like one thing that’s evolving with the occasions, and evolving the place the business is heading?
I believe that’s why it was good to listen to from Atlan, and we appreciated the place they have been positioned in that evolution. We like that Atlan integrates with plenty of tech stacks. For instance, we use Nice Expectations for knowledge high quality in the meanwhile, however we’re contemplating Soda or Monte Carlo, and we discovered Atlan already has an integration with Soda and Monte Carlo. We’re discovering extra examples of that, the place Atlan is changing into extra related.
Conversely, after we have been addressing personally identifiable data, we needed to have the ability to scan our knowledge units. Atlan was fairly clear, saying “We’re not a scanning device, that’s not us.” It was good to have that differentiation. After we checked out Open Metadata, they mentioned that they had scanning functionality, nevertheless it wasn’t as complete as we have been anticipating, and we all know now that this use case is in a special realm.
It’s good to have that readability, and know which path Atlan goes to go.
How do you plan on rolling Atlan out to your customers?
Danni:
So usually in platforming and tooling, we’re very caught up specializing in the know-how and never specializing in the person expertise. That’s the place Atlan can actually assist.
We need to create one thing that’s tangible, and that individuals need to use, so we will drive mass adoption of the platform. With our earlier catalog, we didn’t have a lot adoption, so we’re making {that a} success metric, and one of many nice options in Atlan is that we will customise it to fulfill the wants of differing personas. An idea that hasn’t been historically pushed within the Information Governance area!
We went out to the enterprise and undertook an enormous train, interviewing our stakeholders and potential customers. Now, we actually perceive the use instances, scale and what our customers need from the Information Catalog. Our personas – analysts, producers, house owners and customers will all be supported within the roll out of Atlan, ensuring that their expertise is custom-made inside the device they usually can all perceive and use knowledge successfully for his or her roles.
