How Acceldata Helped T-Cellular’s Knowledge Modernization Technique


When T-Cellular began migrating a few of its information property from an on-prem Hadoop system to cloud-based information platforms, it discovered the transfer liberating. However because it settled right into a hybrid-cloud world, T-Cellular realized prices had been getting out of hand. That’s when it introduced in information observability vendor Acceldata to get a greater deal with on its information.

Like many massive enterprise, T-Cellular relied on a conventional information warehouse to floor vital data to tell enterprise selections. However as the large information growth commenced a few decade in the past, it discovered relational databases might not scale to satisfy its information storage and processing wants.

Round 2015, T-Cellular adopted the Apache Hadoop platform. The telecommunications big discovered that its on-prem Hortonworks Knowledge Platform (HDP) cluster opened up new horizons by way of the scale of the community occasion information it might acquire, retailer, and course of, in line with Vikas Ranjan, senior supervisor of knowledge and analytics engineering at T-Cellular.

“Hadoop was undoubtedly a game-changer by way of how folks had been in a position to unlock the opportunity of large quantity information units, excessive complexity information units, and distributed information processing,” Ranjan says. “Going from 2TB of knowledge per day to greater than 1PB of knowledge per day processing grew to become a actuality for us.”

The early days of T-Cellular’s Hadoop expertise went very effectively, Ranjan says. The corporate adopted highly effective frameworks like Apache Spark and Apache Hive to course of community occasion information. The occasion information arrived in proprietary flat-file like codecs, and T-Cellular transmitted them into trade normal Parquet.

However the large information challenges that drove T-Cellular into the arms of Hadoop within the first place refused to go away. With the expansion of Internet site visitors and introduction of recent applied sciences like 5G and digital actuality, the info simply stored getting larger, with better variability. Managing the Hadoop cluster amid this development grew to become a problem in its personal proper, Ranjan says.

“As we began doing much more analytics and modernization of issues on Hadoop, we bumped into scalability points,” he says. “About 2019 we noticed a tipping level on what Hadoop can do with a few of the limitations and a few of the gaps and the place the info was going by way of scale.”

T-Cellular wanted to course of a lot of very small information, on the order of 1 to 2 trillion community occasions per day. Nonetheless, HDFS isn’t superb at dealing with massive variety of small information, because it results in namenode and reminiscence utilization points that drag down efficiency.

One other situation was machine studying and AI. Whereas Hadoop information lakes had been good for processing and analyzing information, they’re not one of the best platforms for working machine studying and AI, Ranjan says.

“Hadoop was working for us, nevertheless it was not giving us the superior evaluation capabilities, the machine studying capabilities,” he says. “Hadoop is healthier for information lake and information processing, however not pretty much as good for lots of use instances.”

So in 2019, T-Cellular began exploring the way it might increase its information method. Knowledge creation continued to develop exponentially because of 5G and the metaverse, however Hadoop’s information scalability points had been inflicting it to overlook SLAs by way of making information accessible.

“Probably the most vital foreign money is time,” Ranjan says. “We don’t have persistence to do issues 4 hours from now, or 12 hours from now or 24 hours from now.  You wish to remedy the issues as they’re occurring.”

T-Cellular ended up taking a two-pronged method to its information platform modernization. One department stayed on prem, whereas one other department led to the cloud.

For T-Cellular’s most important community occasion information, which resided on its 40PB HDP cluster, the corporate constructed a customized, Java-based in-memory information processing system that runs atop Kubernetes. That system runs on prem subsequent to its Hadoop cluster, which T-Cellular continues to run for information persistence and a few Spark and Hive workloads.

T-Cellular additionally began its cloud journey, across the 12 months 2021. In keeping with Ranjan, the corporate needed the flexibleness to run on all the key cloud platforms, together with AWS, Microsoft Azure, GCP, Databricks, and Snowflake. Like its transfer from a conventional information warehouse to Hadoop, the transfer from Hadoop to the cloud was eye-opening.

“As we go into the cloud world, instantly we noticed the advantages of cloud by way of elasticity, by way of agility,” Ranjan says. “There have been issues we couldn’t do in our on-prem Hadoop system for months. Inside days, we had been in a position to innovate. We had been in a position to ideate, provide you with new use case, on board new customers, given them the artwork of prospects by way of AI and ML which weren’t obtainable within the conventional Hadoop after we had been working in our journey up to now.”

However, alas, the cloud turned out to not be the land of milk and honey. Whereas T-Cellular elevated its agility within the cloud and gained entry to a bunch of recent ML and AI instruments, it got here at a value.

“The cloud works actually, rather well. However we don’t have an infinite funds,” Ranjan says. “We have now very restricted budgets now. We wish to be very value environment friendly, and the way in which the entire cloud is [billed] brings some very complicated challenges by way of learn how to handle the associated fee.”

As beforehand talked about, T-Cellular’s information journey has not led away from Hadoop, which stays a vital information persistence layer for the corporate’s most vital community information within the US. The corporate wanted to get a greater deal with on prices, each with its on-prem information lake and new cloud repositories.  That’s the place Acceldata is available in.

“Acceldata helps us with the general observability,” Ranjan says. “Acceldata helped us with optimization of value on cloud [and] on-prem Hadoop. I believe there was plenty of losing of the info we had been storing. We have now a number of petabytes of knowledge that was not accessed. After which the entire tuning of Hadoop was very, very sophisticated and sophisticated as a result of it is a  high-scale platform. 

What attracted T-Cellular to Acceldata within the first place was its assist for Hadoop, which is a platform that different information observability distributors don’t assist. In keeping with Ranjan, the corporate preferred Acceldata as a result of it might present a single pane of glass for all of its information estates, each on prem Hadoop and cloud information platforms.

“Our [proof of concept] was round Hadoop, after which from there we form of began seeing that worth and increasing,” Ranjan says.

Whereas hasn’t but gone into manufacturing with Acceldata for its Databricks implementation, the early POC exhibits promise, he says.

“What I actually like about that is we had been getting a single pane of view to get the price of all of your workspaces, damaged down by the consumer, damaged down by the workloads, for all of the totally different Databricks implementations now we have and the cluster,” he says. “It offers you all the pieces in a single place, so that you don’t must chase. You don’t must go to totally different locations. You don’t must construct your customized dashboards. It’s multi function place.”

Finally, Acceldata enabled T-Cellular to optimize its Hadoop platform, bettering manageability and enabling it to hit its SLAs once more. Contemplating that the tempo of knowledge creation and innovation exhibits no indicators of letting up, having a software like Acceldata seemingly can pay dividends for T-Cellular sooner or later.
