Migrating To A Cloud Data Warehouse



For most companies today the attraction of cloud computing is too tempting to ignore and one of the areas that is high priority is analytics. Many companies are looking take advantage of new technologies available on the cloud for real-time analytics, machine learning and analysis of huge volumes of multi-structured data, to add to what they already know. However, given that their core analytical systems are data warehouses and data marts sitting in their data centres. it’s not surprising that migrating these systems to the cloud is high on the agenda.

This 1-day course details what is involved in migrating data warehouse and data marts to cloud based Analytical Relational DBMSs such as Amazon Redshift, Google Big Query, Microsoft Azure SQL Data Warehouse, IBM DB2 Warehouse on Cloud, Oracle Autonomous Data Warehouse, Snowflake and Teradata Vantage on Cloud.
