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 Companies, and I’ve been at REA for 2 years now. I graduated in IT from the UK, then labored in numerous consultancy companies in Information and Analytics and developed a powerful 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 numerous 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 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 number of 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 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 will be my subsequent Android mission?” After I was doing that, I got here throughout SQL Server, studying how you must do operational modeling whenever you’re creating one thing like a front-end software. That’s how I made my first step into information. Since then, I’ve been working throughout numerous totally different sorts of knowledge groups.
My first information 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 information utilizing the SAP merchandise. I spent about 5 years in that world, then moved into a number 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.
After I first joined an information staff 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 have been going to be the following large factor. Again then, some individuals 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 grow to be not solely the “bread and butter” of the corporate, nevertheless it’s a possibility for monetization for lots of them, too. It’s good to see that transition occurring, and it’s been fascinating to observe.
Danni Garcia:
I’m a Product Supervisor in Information Companies with a particular background in Information research. I haven’t at all times been in Product. I’ve labored within the know-how trade 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 information staff helps the group?
Surj:
I feel 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 industrial properties and land, as nicely. We’ve additionally performed a number 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 trade in Australia, but additionally present mortgage dealer companies.
So if you wish to promote your property, REA offers the entire bundle. You possibly can promote your property, and in case you want financing, we might help you fiscal your subsequent funding.
We’ve gone by way of an extended journey, and have had a Information Companies staff for an extended time period. The whole lot was decentralized, then it was centralized. Now it’s a little bit of a hybrid, the place we have now a centralized information staff 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 when it comes to 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 little thing from ingestion of knowledge, event-driven structure to machine studying. We’re constructing information belongings to share with exterior firms within the type of an information market.
Danni:
Information Companies exists to help all the inner strains of companies throughout our group. We’re not an operational staff, however a foundational one, that builds information merchandise and capabilities to assist help groups to allow them to efficiently leverage information for his or her merchandise. Our mission is to make it simple to grasp, defend and leverage REA information.
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 clients and shoppers. However what’s occurred is that this wealthy information evolution helps our enterprise grow to be data-driven. A number of the information metrics you see on the REA web site and cellular software 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 a number of worthwhile information. There are a number of initiatives happening now to develop the utilization of knowledge, and over the following two years, we are going to develop our panorama and derive even higher outcomes for our clients and shoppers. to grasp, leverage, then showcase information to our clients and their clients.
What does your information stack appear to be?
Danni:
We now have 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 information utilizing Breeze, constructed on Airflow. Our information lake resolution is BigQuery.
Piyush:
We take 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 have now most of our infrastructure workloads working there. We now have EC2 cases and RDS working there. We now have our personal VPC. We now have a number of load balancers.
From a Information and Analytics perspective, nearly all 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 are experimenting with BigQuery ML on the GCP aspect, as nicely. We even have a self-managed Airflow occasion, in order that’s our information platform.
We’re at present within the strategy of establishing 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 have now each the Tableau desktop and the server model, in the intervening time.
Why seek for an Energetic Metadata Administration resolution? What was lacking?
Surj:
We now have an present open-source information 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 would have liked one thing that’s extra related for the fashionable information stack, which is the course that we’re going in direction of.
There’s additionally a stronger push in our trade towards higher safety of knowledge. We retailer a number of personally identifiable information throughout the enterprise, and a few of our key methods we have now in Information Companies are that we need to first perceive the information, defend it, then leverage it. We would like to have the ability to catalog our information, and perceive how dispersed it’s throughout our warehouses, numerous platforms, in batches, and streams.
We now have a number of information, e.g. we’ve received over two petabytes of knowledge in GCP BigQuery alone. We would like 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 when it comes to governance, processes, and insurance policies, however we need to have the correct tech stack to assist us use this information.
Danni:
There have been some technical limitations, as our earlier information catalog may solely help BigQuery, however we actually needed to help the course of the enterprise when it comes to 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 staff owns information, they leverage it they usually have a accountability to handle it with governance frameworks.
So, to be able to embed Information Governance practices and this cultural shift, we would have liked a software 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 information is and the way it’s being labeled which helps our Privateness initiatives.
We’re nonetheless on a change journey at REA, which could 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, talking to Gartner and reviewing out there tooling throughout the trade. We may have clearly saved 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 standards of a contemporary information stack, offering us the capabilities we want, akin 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 participating with Atlan, particularly with the Skilled Companies staff. The arrogance that they gave us within the tooling once we went by way 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 facets akin 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 may be going, which was our second filtering course of. Once we have been performed choosing our choices, we had to determine which one would swimsuit us finest.
That’s once 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 can be getting out of the software. 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 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 through API. As a result of we have now our information platform working on Airflow, we additionally needed to grasp how nicely every possibility labored with that.
Then we additionally checked out roadmaps and requested ourselves what may occur sooner or later, and if one thing like Atlan’s funding in AI is one thing we should be wanting into, and different future enhancements Atlan or different distributors may present. We have 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:
For those who take 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 important.
When Piyush, Danni and I have been distributors, that’s one thing we have been interested by. Would you like a standard information catalog, which we’ve in all probability seen in banks which have a powerful, ruled, centralized physique, or would you like one thing that’s evolving with the occasions, and evolving the place the trade is heading?
I feel that’s why it was good to listen to from Atlan, and we favored the place they have been positioned in that evolution. We like that Atlan integrates with numerous 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 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, once we have been addressing personally identifiable data, we needed to have the ability to scan our information units. Atlan was fairly clear, saying “We’re not a scanning software, that’s not us.” It was good to have that differentiation. Once we checked out Open Metadata, they stated they’d 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 course 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 consumer expertise. That’s the place Atlan can actually assist.
We need to create one thing that’s tangible, and that folks 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 house!
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 custom-made inside the software they usually can all perceive and use information successfully for his or her roles.
