With hybrid cloud architectures, enterprises get the best of on-premises and cloud environments. IT admins can apply the hybrid model to data warehouses to reap these benefits, but implementation can pose a challenge. A traditional data warehouse locks enterprises into an on-premises system, according to Andy Walter, CEO of AJW-Advisory, an IT advisory service. These limitations make it difficult, if not impossible, to scale IT infrastructure efficiently. With a hybrid data warehouse, admins can bring some data warehousing capabilities into the cloud while maintaining on-premises capabilities.
