How Kyligence Cloud uses Amazon EMR Serverless to simplify OLAP
This post was co-written with Daniel Gu and Yolanda Wang, from Kyligence.
Today, more than ever, organizations realize that modern business runs on data—almost all our interactions with business are based on data, and organizations must use analytics to understand, plan, and improve their operations. That is where Online Analytical Processing (OLAP) comes in. OLAP is designed to manage and analyze big data, enabling organizations to use their data to extract business insights in multiple dimensions.
Kyligence Cloud OLAP solution offers an Intelligent OLAP Platform to simplify multi-dimensional analytics for cloud data lakes. In the past, Kyligence used to deploy and maintain its own Spark clusters based on Amazon Elastic Compute Cloud (Amazon EC2) to handle the multi-dimensional model pre-computing process that required users to build their monitoring and alerting systems to improve the observability and reliability of the Spark cluster. In this post, we present how Kyligence built and end-to-end Kyligence Cloud OLAP solution with Amazon EMR Serverless to simplify deployment and operations, reduce costs, and accelerate time-to-value over the data lake.
What is Amazon EMR Serverless?
Amazon EMR Serverless is a big data cloud platform for running large-scale distributed data processing jobs, and machine learning (ML) applications using open-source analytics frameworks like Apache Spark and Apache Hive. Amazon EMR Serverless makes it easy and cost-effective for data engineers and analysts to run applications without having to tune, operate, optimize, secure, or manage clusters.
What is OLAP?
OLAP is an approach to quickly answer analytics queries at high speeds on large volumes of data, providing capabilities for precomputation, sophisticated data modeling, and multi-dimensional analytics by rolling up large, sometimes separate datasets into a multi-dimensional database known as an OLAP Cube that enables “slicing and dicing” of data from different viewpoints for a streamlined query experience. Apache Kylin, Apache Druid, and ClickHouse are some of the popular OLAP tools.
Although OLAP tools have been successfully used in various industries, they still face many challenges：
- Dependence on IT organizations – Traditional OLAP tools require complex infrastructure to run large-scale data computing. It requires a large team of IT professionals to operate and maintain this infrastructure, resulting in high costs.
- Need for large compute resources – Traditional OLAP tools need huge amount of computing resources for processing, and transforming data through a series of specific steps toward a concrete goal. Lack of computational capabilities leads to longer response times, limits the amount of data that can be processed, and impedes the flexibility of the OLAP tool greatly . As a result, data analysts are often confined to narrow datasets, incapable of analyzing all the data freely.
- Inefficient usage of resources in the cloud – When a large-scale data modeling calculation is performed in the cloud, the cost estimation tools estimate and deploy the corresponding computing resources. However, the utilization rate of resources is often not very high, resulting in inefficient usage of resources.
With OLAP integrated with Amazon EMR Serverless, OLAP tools can use Amazon EMR Serverless as a serverless computing resource pool to complete data processing jobs, which simplifies and enhances user experience.

Benefits of using Kyligence Cloud with Amazon EMR Serverless
In the past, Kyligence used to deploy and maintain its own Spark clusters based on Amazon Elastic Compute Cloud (Amazon EC2) to handle the multi-dimensional model pre-computing process that required Kyligence users to build their monitoring and alerting systems to improve the observability and reliability of the Spark clusters.
Now, running Kyligence on Amazon EMR Serverless offers a more cost-effective, and high-performance way to run cloud analytics on AWS:
- Simplified deployment on the cloud – With managed services, you don’t need to consider the lifecycle of the underlying infrastructure and resources. This greatly reduces application complexity and simplifies the deployment of Kyligence Cloud.
- Improve performance on the cloud – With the help of Amazon EMR Serverless, it provides a refined scaling strategy, which can help Kyligence Cloud spin up and recycle resources faster. In Kyligence performance benchmark testing, we observed 15–20% faster performance compared to open-source Spark cluster for index building.
- Reduce the difficulty of operation and maintenance – With the help of Amazon EMR Serverless capabilities, operation and maintenance personnel can easily maintain the capacity and running status of computing resources without having to understand the underlying analysis framework.
- Cost-optimization on the cloud – Amazon EMR Serverless provides a refined scaling strategy that can automatically determine the resources that the application needs, acquires these resources to process your jobs, and releases the resources when the jobs complete. You only pay for the resources used by the application, which helps reduce the Total Cost of Operations (TCO) on the cloud.
