How-to: Avoid Cloud Vendor Lock-In to Minimize Cost and Risk

Categories: CDH Cloud How-to

Learn how to use Cloudera to spin up Apache Hadoop clusters across multiple cloud providers to take advantage of competing prices and avoid infrastructure lock-in.

Why is a multi-cloud strategy important?

In the early days of Cloudera, it was a fair assumption that our software would be running on industry-standard servers that were purchased, owned, and operated by the client in their own data center. In the last few years,

Data Engineering with Cloudera Altus

Categories: Altus Cloud Hive Spark

With modern businesses dealing with an ever-increasing volume of data, and an expanding set of data sources, the data engineering process that enables analysis, visualization, and reporting only becomes more important.

When considering running data engineering workloads in the public cloud, there are capabilities which enable different operational models from on-premises deployments. The key factors here are the presence of a distinct storage layer within the cloud environment, and the ability to provision compute resources on-demand (e.g.: with Amazon’s S3 and EC2 respectively).

How To Set Up a Shared Amazon RDS as Your Hive Metastore

Categories: Cloud Hadoop Hive How-to Impala Spark Use Case

Before CDH 5.10, every CDH cluster had to have its own Apache Hive Metastore (HMS) backend database. This model is ideal for clusters where each cluster contains the data locally along with the metadata. In the cloud, however, many CDH clusters run directly on a shared object store (like Amazon S3), making it possible for the data to live across multiple clusters and beyond any cluster’s lifespan. In this scenario clusters need to regenerate and coordinate metadata for the underlying shared data individually.
