Software Engineer Mid-Market (51-1000 emp.) 11/3/2025 "Seamless Integration and Unified Features for Advanced Users" 5/5 What do you like best about ILUM? What I appreciate most about ILUM is its Ease of Integration. The platform is built to be open and modular, allowing it to connect seamlessly with the tools we already rely on, such as Airflow, dbt, Jupyter, and various BI tools through JDBC. We didn't have to overhaul our existing workflows; ILUM integrated effortlessly, which meant less hassle during implementation and a much quicker realization of value—something I consider a major advantage. Another standout aspect is the impressive range of features combined with how easy it is to use. Since ILUM is a unified platform, I can run SQL queries, review data lineage, and launch Spark jobs or notebooks all from a single interface, eliminating the need to constantly switch between different tools. Having that centralized control is incredibly convenient. The process of implementing ILUM is both straightforward and nuanced, but for the most part, it's simple if you have the right infrastructure in place. Because ILUM is Kubernetes-native and deployed via Helm charts, if you already have a Kubernetes cluster set up, you can get the core components—Spark and the UI—up and running in less than five minutes using a basic Helm command. Personally, I use ILUM as my main platform nearly every day in my work. Review collected by and hosted on G2.com. What do you dislike about ILUM? If I had to nitpick, the initial UI for the truly deep engineering stuff can be a little much for new users, but once you get past the initial setup (which is covered well by Customer Support and training), the daily use is very intuitive. The Interactive Sessions feature is also amazing for cutting down on Spark job startup time, making my day-to-day work way more efficient. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? ILUM solves a few major headaches that were common in the big data world. The main problem is fragmentation—trying to stitch together separate, expensive data lakes and data warehouses, which leads to messy data silos, inconsistent results, and a lot of unnecessary work. Older proprietary systems like Cloudera or Databricks are costly and lock you in. ILUM gets rid of those problems. It's an open-source based Data Lakehouse platform that unifies everything. For me as a user, this translates to tangible benefits. First, it is much faster. The interactive Spark sessions eliminate those 20-40 second job start times, and processing can be up to twice as fast overall. This means I'm not waiting on the infrastructure; I'm actually doing my job. Second, it's cheaper and more efficient. The platform is zero-license, Kubernetes-native, and runs anywhere (cloud, on-prem, hybrid), which drastically cuts infrastructure costs—we talk about 60% savings for clients. That budget can go to actual development, not just licensing fees. Third, it provides clarity and governance with features like automated Data Lineage and a central Data Catalog, so I can trust the data's quality and know exactly where it's been. In short, it lets me focus on the challenging and valuable work of data science and analytics instead of wrestling with complex, slow, and expensive tools. Review collected by and hosted on G2.com.

Head of Technology Banking Enterprise (\> 1000 emp.) 10/26/2025 "From Hadoop to K8s with lower TCO" 5/5 What do you like best about ILUM? We can own the entire environment on-prem today and move it to our private cloud tomorrow without changing the way teams work, the Kubernetes-first model makes that portability real. For the organization, that means modernization on our terms: virtual clusters with quotas per team, job-level cost guidance, built-in lineage/ERD, and an OSS toolchain (Airflow, dbt, MLflow, Superset) that integrates cleanly. For the team, day-to-day delivery is faster: the SQL editor/notebooks and Jupyter are in one place, deployments are straightforward, and we use it every day across dev/UAT/prod without juggling licenses. Implementation was practical rather than painful, Hive Metastore slotted in, and integration with existing pipelines was mostly configuration, not rewrites. Review collected by and hosted on G2.com. What do you dislike about ILUM? Owning the stack means taking Kubernetes seriously: capacity planning, RBAC, and policy hardening need attention up front, especially if you’re moving from a managed Hadoop/YARN world. Lineage can be noisy until you define domains/tags, and centralizing logs from the integrated OSS tools into your SIEM takes a bit of plumbing. None of this is blocking, but you should plan a short enablement sprint so the platform lands well for both the team and the business. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? Ilum solves three concrete problems for us: getting off aging Hadoop, taking control of costs, and speeding up delivery. We moved our estate from Cloudera/YARN to a Kubernetes lakehouse we can run fully on-prem today and shift to our private cloud or a mixed K8s setup without rewriting pipelines. Job-level Spark cost insights and configuration recommendations stopped over-provisioning, while virtual clusters with quotas let us allocate budget by team and keep runaway spend in check. The integrated OSS stack (Airflow, dbt, MLflow, Superset) replaced multiple paid tools, and automatic lineage/ERD/column lineage gives audit-ready traceability for regulatory change. For the team, the built-in SQL editor, notebooks, and Jupyter made engineering tasks faster and releases simpler across dev/UAT/prod. Net result: lower TCO, predictable operations we own, and a modern platform that actually accelerates delivery. Review collected by and hosted on G2.com.

Head of Data Management Information Technology and Services Enterprise (\> 1000 emp.) 10/21/2025 "ILUM Simplifies Spark Management—Great for Delta, Easy Onboarding with Helpful Docs" 4.5/5 What do you like best about ILUM? Being able to manage and monitor my Spark cluster in an on-premise environment through a single, user-friendly web interface, as well as through a REST API, has greatly simplified the process of launching Spark jobs for my client applications, integration was not a problem thanks to well documented REST API. ILUMs has saved me considerable time and made managing Kubernetes-based Spark deployments much easier. I also appreciate its support for the Delta format, which is the one I rely on most often. Overall, ILUM has significantly streamlined the implementation of a full-stack data lakehouse solution for both myself and my company. Review collected by and hosted on G2.com. What do you dislike about ILUM? The only aspect that might be challenging, though not exactly a drawback, is that you need some basic knowledge of K8S when starting with ILUM. Fortunately, the documentation provided by ILUM is very helpful and makes the learning process much easier. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? Managing and scaling our data processing environment was a significant challenge. Before using ILUM, setting up and especially monitoring Spark workloads was both time-consuming and prone to errors. Additionally, ILUM helped us save a considerable amount of costs compared to Cloudera, which we had used previously. Review collected by and hosted on G2.com.

What makes ilum the best option for me is its ability to run on-premise within our company's isolated, air-gapped data center. For testing and UAT, we are able to use our private cloud, which adds flexibility. Ilum stands out because it operates seamlessly both in the cloud and on-premise. I also find it very user-friendly; our initial test deployment took just one day. We now use ilum daily. The customer support team is excellent, often responding even faster than our standard SLA requires. The range of features matches industry standards, but what impresses me most is how quickly new feature requests are implemented—sometimes they appear in the very next release. Integration with external modules is also outstanding, overall implementation is also great. Review collected by and hosted on G2.com. What do you dislike about ILUM? I haven't encountered any major issues. However, it would be helpful to have a few additional modules focused on ETL. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? We were searching for a solution to secure our data within our private data center. It was important for us to maintain ownership of our data, which led us to choose an open platform that functions effectively both on-premises and in the cloud. Previously, we struggled with the lack of data lineage, but ilum has brought that concept into our organization. Review collected by and hosted on G2.com.

What I like most about ILUM is how smoothly it integrates with my existing systems and how much it simplifies working with Spark on Kubernetes. I use ILUM to connect my internal app with ILUM services, allowing me to run Spark sessions as microservices and handle heavy data computations quickly and efficiently. This setup lets me manage Spark workloads without having to worry about complex infrastructure — ILUM takes care of it behind the scenes. I store and organize my data in Delta tables using ILUM’s built-in integration, which I find extremely useful for daily analytics. I frequently query my data through the ILUM-SQL JDBC interface and visualize results using Superset, which is tightly integrated into the platform. This combination gives me a smooth workflow from data processing to visualization, all within one environment. Deployment was straightforward — I run ILUM in my own on-prem Kubernetes cluster, and it only required basic K8s knowledge to get everything up and running. Once deployed, it has been stable and reliable. The UI is one of my favorite parts: it’s clean, intuitive, and provides an all-in-one overview of everything from Spark jobs to data tables and SQL queries. Lastly, the support team has been excellent — every time I had a question or issue, they responded quickly with helpful, practical answers. Overall, ILUM provides a powerful, easy-to-use environment for managing Spark workloads, organizing data, and analyzing it visually, all in one integrated platform. Review collected by and hosted on G2.com. What do you dislike about ILUM? There isn’t much to dislike, but a few areas could still be improved. Since ILUM provides such a wide range of features in one platform, some advanced configuration options can feel a bit hidden or require digging through documentation to fully understand. While the UI is very user-friendly for daily work, some of the deeper administrative settings — like custom Spark configurations or advanced access control — could be easier to manage directly from the interface. Because I run ILUM on-prem in my own Kubernetes environment, initial tuning of resources and storage integration required some experimentation to find the right balance. It would be great to have more examples or automation for these parts of the setup. Also, although ILUM’s Superset integration works very well, large queries or visualizations sometimes take time to load when working with very big Delta tables — not a dealbreaker, but something to keep optimizing. Overall, these are minor issues compared to the value ILUM provides. The platform is improving quickly, and support has been responsive whenever I’ve needed help fine-tuning configurations. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? ILUM helps me solve the challenge of running and managing large-scale Spark workloads efficiently in a Kubernetes-based environment. Before using ILUM, setting up Spark sessions and maintaining the infrastructure around them was time-consuming and required a lot of manual configuration. With ILUM, I can easily launch and manage Spark sessions as microservices, which makes scaling computations and handling data processing tasks much faster and more reliable. It also simplifies data organization — ILUM’s integration with Delta tables lets me store, update, and query large datasets efficiently while keeping full data consistency. The ILUM-SQL JDBC interface and built-in Superset integration make it easy to run analytics queries and visualize results without leaving the platform. Running ILUM on my on-prem Kubernetes cluster gives me full control over resources while keeping management simple. The all-in-one design means I can handle Spark jobs, data management, and visualization from a single place. Overall, ILUM has streamlined my data processing workflows, reduced setup overhead, and allowed me to focus on insights rather than infrastructure. Review collected by and hosted on G2.com.

It turns delivery into a repeatable practice instead of glue work. I open a PR, pick a template, and get a compliant workspace with CI, secrets, RBAC, cost tags, approvals, and lineage set the same way every time. In numbers, we run about 180 scheduled pipelines and 30 long-running services, roughly 600 to 800 runs per day, with a 99.2% success rate last quarter. MTTR fell from 85 to 38 minutes and change failure rate sits under 5%. Ease of implementation was real, not marketing. We were live in two sprints, and ease of integration matched that story: SSO and Git mapped cleanly, storage and the warehouse stayed where they were, Kafka and observability slotted in, no code rewrites, policies stayed intact. Ease of use is strong too: the UI is clear, paved templates keep teams on the rails, errors include actionable hints, and one console for jobs, lineage, and cost means less tool hopping. Our first pipeline hit prod in week one. Support is the safety net I trust. During a release freeze we hit a nasty networking edge case, an engineer joined live, traced the egress policy, and we shipped that afternoon. A later P1 around permissions closed in under 48 hours with a runbook we still use. Day to day it feels like a platform for professionals that helps us meet SLOs, not a toolbox we have to assemble. Review collected by and hosted on G2.com. What do you dislike about ILUM? It is not a one-click black box - some Kubernetes basics help at the start, especially networking, storage classes, and RBAC. The console is more functional than flashy; a native dependency timeline with simple bulk actions like pause or owner change would save us scripting. Advanced networking and GPU scheduling needed a bit of hand holding. On the plus side, support actually shows up: they replied same day to the timeline request and put us on early access, and a P1 around egress rules was resolved in under 48 hours with a clear runbook we still use. Once the guardrails are set, it is stable and predictable, so these are minor UX and learning-curve items rather than daily blockers. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? We used to fight ticket queues, drift between teams’ pipelines, and noisy on-call from brittle cron scripts. Secrets and configs lived in too many places, so audits were a scavenger hunt and a new workspace took days. Now I open a PR, pick a template, and get the same compliant setup every time: CI, secrets, RBAC, approvals, lineage, and cost tags. Jobs, logs, metrics, and spend live in one console, so we diagnose issues without tool hopping. The impact is measurable: lead time went from weeks to days, run success sits around 99%, MTTR fell from 85 to 38 minutes, change failure rate is under 5%, and platform spend is down roughly 25–30% from rightsizing and autoscaling. Audit requests that used to take days are answered in hours because evidence is automatic. A concrete win: we rebuilt a flaky nightly enrichment on the standard Spark template, cut runtime from 70 to 32 minutes, removed egress copies, and eliminated the night-shift pages. It feels calmer and faster, and we hit our SLOs more reliably. Review collected by and hosted on G2.com.

What I like most about Ilum is that it runs where you need it to run. On-prem, in the cloud, hybrid, it doesn’t really matter. You're not boxed into someone else’s ecosystem or forced to rebuild everything from scratch. That flexibility matters when you already have a working stack. We didn’t have to rip out tools we trust or jump through hoops to make Ilum fit. It plugged into what we had, Kubernetes, Spark, Jupyter, Airflow and just worked. Getting started was surprisingly straightforward. We had a functional environment running quickly, without months of onboarding or vendor hand-holding. What this really means is we kept control. Over cost, over data, over architecture. Long-term ownership vs. convenience, that trade-off is worth thinking about. Ilum makes the choice easier. Review collected by and hosted on G2.com. What do you dislike about ILUM? You’ll get more out of Ilum if you have an experienced team. It’s not 100% hand-holding you through setup like a managed cloud platform would. That’s fine for us, but it’s worth calling out. You trade polish for total control. Still, when we hit a wall, the team behind Ilum responded quickly and usually fixed the issue fast. So while there are gaps, they don’t stay gaps for long. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? We're building AI product that need to work across very different environments, healthcare, finance, telco, you name it. Each customer comes with their own infrastructure, data sources, and compliance needs. We needed a platform flexible enough to handle all that without slowing us down. Ilum solves that problem. It gives us one consistent data layer we can deploy anywhere, on-prem, in the cloud, hybrid setups, whatever the client needs. That means we don’t have to redesign our pipeline every time. Spark, Jupyter, MLflow, Airflow. it’s all there, and it plays well together out of the box. We can move faster, adapt to new environments, and still keep control of the full AI lifecycle, from data ingestion to model deployment. And because we’re not locked into any vendor, we can offer our customers more transparent, cost-efficient solutions. That flexibility is what makes Ilum such a valuable piece of our stack.

Head of Data Strategy Banking Enterprise (\> 1000 emp.) 10/20/2025 "Flexible, Cost-Effective Solution with Stellar Support" 4.5/5 What do you like best about ILUM? I appreciate that ILUM is a free platform, which makes it the most cost-effective choice for us as a data lakehouse platform. The fact that it integrates seamlessly with our existing systems for data processing, visualization, ETL, and more is invaluable. By handing over the management of tooling to ILUM, we can focus more on data processing rather than on infrastructure, significantly optimizing our workflows. I find the ability to choose where and how to run workloads highly beneficial because it saves us approximately 30% on compute costs. The safety of our data being always in our own hands is reassuring. ILUM manages to support advanced configurations with platforms such as Apache Airflow and integrates well with Apache Spark, which considerably boosts our team's efficiency by enabling autoconfiguration and microservices creation. I admire ILUM's adaptability and its team’s responsiveness; we request features, and the development team quickly implements them. This has led to a platform that grows reliably with our needs, much to our developers' satisfaction, providing them access to cutting-edge tools. Lastly, I value the helpfulness of ILUM’s support team, who assisted us in tailoring the platform to meet our specific needs, ensuring we fully leverage its capabilities. Review collected by and hosted on G2.com. What do you dislike about ILUM? I found the initial setup of ILUM to be quite demanding due to the heavy reliance on Kubernetes, Apache Spark, Apache Hive, and the need to consult internal documentation. This complexity requires specific knowledge to understand what affects what and how to configure it properly. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? ILUM cuts our compute costs by 30%, allows us to run workloads flexibly, ensures data security, enables developer satisfaction with cutting-edge tools, and increases team efficiency through auto-configuration of Apache Spark Jobs.

Head of Data Mid-Market (51-1000 emp.) 8/8/2025 "Reliable Data Infrastructure for Real-World Engineering" 5/5 What do you like best about ILUM? What we like most about Ilum is that it works the way we need it to. No extra layers of complexity. No surprises. We deal with a mix of data from hardware tests, system logs, simulation outputs, and engineering tools. Before Ilum, pulling that all together was slow and error-prone. Ilum gave us a clean foundation from the start. We did not need a huge rollout or long planning sessions. We got it up and running fast, using our existing systems. That was a major win for our team. It connected smoothly with the tools we were already using. Data Catalog, SQL, BI Tools, Spark, Jupyter, MLflow, and Airflow all worked out of the box. We did not have to rebuild or rewire anything. It saved us time and helped us avoid months of migration effort. The interface is simple and makes sense. Engineers can jump in, run queries, explore datasets, and manage jobs without needing to learn a new language. It became part of our workflow right away and continues to be something we rely on every day. Support has been reliable and responsive. When we reach out, we get helpful answers quickly from people who understand real use cases, not just the surface of the product. There is also a lot of depth. Ilum handles versioned datasets, job scheduling, lineage tracking, and query access all in one environment. That kind of power without extra weight is rare. What we value most is that Ilum does not try to take over our workflow. It fits into it and makes it better. For us, that is what made it the right choice. Review collected by and hosted on G2.com. What do you dislike about ILUM? Some parts of the interface still feel a bit raw, and the docs could go deeper in a few places. But none of it gets in the way. Ilum does what we need it to do, and these are small things compared to how solid and reliable the core platform is. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? Ilum solved the mess of scattered, inconsistent data across our teams. We used to waste time chasing files, double-checking versions, and trying to make sense of logs, simulations, and test data spread across tools. That made it hard to trust the data or move fast. Now we have one place to organize, clean, and track everything. Our data is structured, versioned, and ready to use. That gives our engineers more time to focus on actual work instead of fighting the platform. It also made it possible to build repeatable pipelines and train models with confidence. Bottom line, we’re moving faster, with fewer mistakes, and better collaboration across teams. Review collected by and hosted on G2.com.

Head of Data Intelligence Telecommunications Enterprise (\> 1000 emp.) 7/31/2025 "Ilum connects the dots between data and real AI" 5/5 What do you like best about ILUM? Ilum helped our company clean up the data mess that used to block serious AI work. Instead of scattered files, multiple storage layers, and unclear schemas, we finally had one consistent layer where all the data lived, structured, unstructured, didn’t matter. It was versioned, searchable, trackable, and easy to work with. No more guessing which file was the right one. That foundation made it possible to build high-quality, trustworthy datasets. From there, everything clicked. We could train models without wrangling chaos first. Jupyter and MLflow worked out of the box. Pipelines actually ran cleanly. Ilum didn’t just help with AI, it made AI feasible in our environment. We’re using it daily now. Spark jobs, scheduled pipelines, notebooks, data exploration, metadata tracking, monitoring, all of it in one place. It replaced a patchwork of tools and made the whole platform easier to manage. Setup was fast. We didn’t need outside consultants. It worked with our existing stack and auth, and the UI is simple enough that non-engineers on the team can still explore data and run queries without friction. Integration was surprisingly smooth. Ilum fit into our stack without forcing any major rewrites. We deployed it on Kubernetes, wired it to our existing GitLab auth, connected it to both cloud object storage and on-prem HDFS, and it just worked. Support has also been solid. Helpful responses, quick turnaround, and not just generic copy-paste replies—actual solutions that fixed problems. What I like most is that Ilum gives you a lot of power without feeling heavy. The features are deep, but they make sense. You don’t have to rebuild your world to fit it in. It plays well with what you already have and gives you structure without locking you in. Review collected by and hosted on G2.com. What do you dislike about ILUM? Some parts of Ilum still feel a bit unpolished. The interface works but looks plain in some spots. Things like setup or more advanced tasks could use better instructions or smarter starting settings. Review collected by and hosted on G2.com. What problems is ILUM solving and how is that benefiting you? The biggest problem Ilum solved for our company was fragmented, unreliable data. We had data scattered across tools, teams, and formats, some in files, some in databases, some in notebooks no one touched for months. There was no single source of truth, and without that, any attempt to build AI was dead on arrival. Ilum changed that. It gave us a unified place to clean, structure, and access all our data. We were able to build master records, track changes, and make everything auditable. Once we had that foundation, our machine learning pipelines finally had something trustworthy to run on. Less time wrangling data, more time building real models. We can now train, retrain, and deploy AI workflows across teams with confidence because we’re not guessing anymore. We're working with real data that we understand and control. Review collected by and hosted on G2.com.
