2 Is a data mesh right for you?

This chapter covers

Introducing the data mesh to your organization
Considering decision drivers before choosing a data architecture
Comparing the data mesh to other popular data architectures
Transforming your organization’s architecture into a data mesh

In the first chapter, we explained the meaning of data mesh. We also explained why your company should consider implementing it. In this chapter, we answer two other essential questions:

Should I implement a data mesh in my business (i.e., what are data mesh drivers)?
How much effort does it take to implement a data mesh (i.e., would the benefits outweigh the effort of its implementation)?

The presence of the first question may surprise you in the context ...
