Data Warehousing in the Age of Artificial Intelligence

Chapter 9. Strategies for Ubiquitous Deployment

In today’s market, enterprises need the flexibility to migrate, expand, and burst their storage and compute capacity both on-premises and in the cloud. As companies move to the cloud, the ability to span on-premises and cloud deployments remains a critical enterprise enabler. In this chapter, we take a look at hybrid cloud strategies.

Introduction to the Hybrid Cloud Model

Hybrid cloud generally refers to a combination of deployments across traditional on-premises infrastructure and public cloud infrastructure. Given the relatively new deployment options available, this can lead to a host of questions about more specific definitions. We will use the following broad terms to delineate.

Single Application Stack

In this model, different parts of the entire architecture will span across on-premises and cloud into a single application stack, as depicted in Figure 9-1. For example, the database might reside in a corporate datacenter, but the business intelligence (BI) layer might reside on the cloud. The BI application in the cloud will issue queries to the on-premises database, which will return results back to the cloud.
