Managing data analytics in a hybrid cloud
Managing Data Analytics in a Hybrid Cloud discusses challenges with traditional analytics approaches and proposes using shared data lakes with dynamic compute clusters. Common challenges include explosive analytics team growth leading to resource contention, and duplicating large datasets for each cluster. The proposed approach uses shared object storage to hold unified datasets accessed by multiple ephemeral analytics clusters provisioned on-demand. This allows teams independent resources while avoiding duplicate storage costs and improving agility. The document outlines example architectures and benefits of this shared data lake approach when implemented on a private or public cloud.

EXCESSIVE CAPEX AND OPEX due to multi-cluster solutions without shared data. Do you do big data analytics on-premises? Do you have multi-PB data sets? Do you have multiple Spark/Hadoop clusters? Do these Spark/Hadoop clusters need to share data sets? Do you also have non Spark/Hadoop tools that need access to these data sets? PROBLEMS HOW YOU KNOW IT’S YOU
- 24. INSERT DESIGNATOR, IFNEEDED RED HAT CONFIDENTIAL ONE CUSTOMER’S UNSOLICITED TESTIMONY “We managed to deliver tremendous value to our organization”: ● Releasing lock on data: moving the HDFS to an open access object store and opening the data process to more processes and analysis. ● Releasing lock on compute: now we’re able to spin up and decommission compute power according to customer needs and utilize cloud benefits (including GPU incorporation in zero time and effort), without worrying about the data. ● Releasing lock on innovation: we can now allow anyone to try and build something new without the fear of messing things up (data or cluster wise). We’ve built an environment that can tolerant mistakes at all levels (process and data), and by doing so, our developers can be much more daring.“
