This interview has been edited for brevity and readability.
May 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 a variety of consultancy companies in Information and Analytics and developed a robust background in cloud platforms and information structure. I migrated to Australia about seven years in the past, with twenty years of expertise in information throughout varied industries together with Media, Telecommunications, Finance, E-commerce and Banking.
I joined REA and was very eager on the function that I used to be provided and the workforce I used to be coming into. What actually enticed me was working with an organization that had a startup mentality, and had been excited to push and ship outcomes. Beforehand, I’ve labored with massive banks the place there’s numerous paperwork 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 after I was ending my Bachelors in Software program Engineering and wanted to decide about what I wished to do subsequent.
I began as an Android developer again when it appeared like all people’s subsequent factor was “What’s going to be my subsequent Android mission?” After I was doing that, I got here throughout SQL Server, studying how you need to do operational modeling if you’re creating one thing like a front-end utility. That’s how I made my first step into information. Since then, I’ve been working throughout a variety of totally different varieties of knowledge groups.
My first information workforce was a Information Administration workforce for a public firm in Australia. They had been ranging from zero, constructing an entire greenfield ecosystem for his or her information utilizing the SAP merchandise. I spent about 5 years in that world, then moved into numerous 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.
After I first joined an information workforce again in 2012, what actually stood out to me on the time was that information was stated to be “the brand new oil”, and that Information & Analytics had been going to be the following huge factor. Again then, some individuals began doing Machine Studying and enjoying round with R Studio, however it was by no means the “bread and butter” of any firm, simply a kind of “north star” form of initiatives.
Abruptly, now 10 years down the road, it’s develop into not solely the “bread and butter” of the corporate, however it’s a possibility for monetization for lots of them, too. It’s good to see that transition taking place, 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 expertise business for nearly a decade now throughout many alternative areas and roles in each massive and small organizations, however I began out as a Information Analyst.
Would you thoughts describing REA, and the way your information workforce 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 sturdy 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 carried out numerous mergers and acquisitions. For instance in Australia, we’ve purchased a agency known as Mortgage Selection that enables 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 supplies the entire bundle. You possibly can promote your property, and when you want financing, we will help you financial your subsequent funding.
We’ve gone by means of an extended journey, and have had a Information Providers workforce for an extended time period. All the pieces was decentralized, then it was centralized. Now it’s a little bit of a hybrid, the place we now have a centralized information workforce constructing out the centralized information platform with key capabilities for use throughout the group, with decentralized information possession. We are attempting to align with a Information Mesh method by way of how we construct out our platform capabilities and adoption of “information as a product” throughout the group.
We’re multi-cloud, each AWS and GCP, which brings its personal challenges, and we do every thing from ingestion of knowledge, event-driven structure to machine studying. We’re constructing information property to share with exterior firms within the type of an information market.
Danni:
Information Providers exists to assist the entire inner strains of companies throughout our group. We’re not an operational workforce, however a foundational one, that builds information merchandise and capabilities to assist assist groups to allow them to efficiently leverage information for his or her merchandise. Our mission is to make it straightforward to grasp, defend and leverage REA information.
Piyush:
I’ll add that during the last couple of years, REA has predominantly seen themselves as a listings enterprise. It’s nonetheless a listings enterprise, offering the very best listings info potential out to prospects and customers. However what’s occurred is that this wealthy information evolution helps our enterprise develop into data-driven. A few of the information metrics you see on the REA web site and cell utility are principally derived from the work that the group has put in to develop our Information & Analytics and ML follow to drive higher resolution making.
We now have numerous helpful information. There are numerous initiatives happening now to increase the utilization of knowledge, and over the following two years, we are going to develop our panorama and derive even higher outcomes for our prospects and customers. to grasp, leverage, then showcase information to our prospects and their prospects.
What does your information stack seem like?
Danni:
We now have a real-time ingestion platform known as Hydro utilizing MSK, which is a custom-built streaming platform. Then we now have our batch platform, which ingests batch information utilizing Breeze, constructed on Airflow. Our information lake answer is BigQuery.
Piyush:
We have a look at ourselves as a poly-cloud firm, utilizing each AWS and Google Cloud Platform, in the intervening time.
From an AWS perspective, we now have most of our infrastructure workloads operating there. We now have EC2 situations and RDS operating there. We now have our personal VPC. We now have a number of load balancers.
From a Information and Analytics perspective, the vast majority of our workloads are in GCP. We’re at present 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 can be experimenting with BigQuery ML on the GCP facet, as effectively. We even have a self-managed Airflow occasion, in order that’s our information platform.
We’re at present within the technique of organising our personal event-driven structure framework utilizing Kafka, which is on AWS MSK.
Other than that, our Tableau entrance finish is used for reporting, so we now have each the Tableau desktop and the server model, in the intervening time.
Why seek for an Lively Metadata Administration answer? What was lacking?
Surj:
We now have an current open-source information catalog that we now have 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 information stack, which is the route that we’re going in the direction of.
There’s additionally a stronger push in our business towards higher safety of knowledge. We retailer numerous personally identifiable information throughout the enterprise, and a few of our key methods we now have in Information Providers are that we wish to first perceive the info, defend it, then leverage it. We wish to have the ability to catalog our information, and perceive how dispersed it’s throughout our warehouses, varied platforms, in batches, and streams.
We now have numerous information, e.g. we’ve bought over two petabytes of knowledge in GCP BigQuery alone. We wish to have the ability to perceive what information is, the place it’s put collectively, and apply extra rigor to it. We now have good frameworks internally by way of governance, processes, and insurance policies, however we wish to have the appropriate tech stack to assist us use this information.
Danni:
There have been some technical limitations, as our earlier information catalog may solely assist BigQuery, however we actually wished to assist the route 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 desires to implement Information Mesh and ‘Information as a Product’ mindset throughout the group. Each workforce owns information, they leverage it and so they have a accountability to handle it with governance frameworks.
So, with the intention to embed Information Governance practices and this cultural shift, we wanted a instrument to assist 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 information is and the way it’s being categorized which helps our Privateness initiatives.
We’re nonetheless on a metamorphosis journey at REA, which may be very thrilling. A brand new information 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 wished 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 standards of a contemporary information stack, offering us the capabilities we’d like, similar to self-service tooling, an open API, and integrations to quite a lot of expertise stacks which had been all essential to us.
We had an overwhelmingly good expertise participating with Atlan, particularly with the Skilled Providers workforce. The boldness that they gave us within the tooling after we went by means of our use circumstances drove a sense of sturdy 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 circumstances.
As soon as we did that, we went again and checked out totally different points similar to pricing and used that as a filtering mechanism. We additionally regarded on the future roadmap of these firms to determine the place every firm could be going, which was our second filtering course of. Once we had been carried out choosing our choices, we had to determine which one would swimsuit us greatest.
That’s after we did a light-weight proof of worth the place we created high-level analysis standards the place all people concerned may rating totally different capabilities from 1-10. The workforce included a supply supervisor, a product supervisor, an architect, and builders, simply to get a holistic view of the expertise all people could be getting out of the instrument. After that scoring, we made a light-weight suggestion and introduced it to our executives.
A few of what we had been within the analysis standards had been issues like understanding what information sources we may combine to, what safety regarded like, and ideas like extensibility so we may very well be versatile sufficient to increase the catalog programmatically or by way of API. As a result of we now have our information platform operating on Airflow, we additionally wished to grasp how effectively every possibility 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 had been making an attempt to get an understanding of the following two or three years, as a result of if we’re investing, we’re investing with a long-term perspective.
Surj:
If you happen to 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 information catalogs for a very long time, however the evolution has been vital.
When Piyush, Danni and I had been distributors, that’s one thing we had been occupied with. Would you like a standard information catalog, which we’ve in all probability 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 preferred the place they had been positioned in that evolution. We like that Atlan integrates with a variety of tech stacks. For instance, we use Nice Expectations for information high quality in the intervening time, however we’re contemplating Soda or Monte Carlo, and we realized Atlan already has an integration with Soda and Monte Carlo. We’re discovering extra examples of that, the place Atlan is turning into extra related.
Conversely, after we had been addressing personally identifiable info, we wished to have the ability to scan our information units. Atlan was fairly clear, saying “We’re not a scanning instrument, that’s not us.” It was good to have that differentiation. Once we checked out Open Metadata, they stated they’d scanning functionality, however it wasn’t as complete as we had been anticipating, and we all know now that this use case is in a unique realm.
It’s good to have that readability, and know which route Atlan goes to go.
How do you propose on rolling Atlan out to your customers?
Danni:
So typically in platforming and tooling, we’re very caught up specializing in the expertise and never specializing in the consumer expertise. That’s the place Atlan can actually assist.
We wish to create one thing that’s tangible, and that folks wish to use, so we are able to 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 are able to customise it to satisfy 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 a giant train, interviewing our stakeholders and potential customers. Now, we actually perceive the use circumstances, 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 personalized inside the instrument and so they can all perceive and use information successfully for his or her roles.
