What a distributed system enables you to do is scale horizontally. Going back to our previous example of the single database server, the only way to handle more traffic would be to upgrade the hardware the database is running on. This is called scaling vertically.
According to remuneration-tracker Payscale, the median base database administrator salary across the U.S. was $67,733 in 2015, or a base hourly rate of $22. However, this is simply a rough average, ranging from a starting salary in the low 40ks for an entry-level DBA position, to the high $200ks for an expert, senior database administrator in charge of multi-terabyte distributed databases for large corporations. These senior-level positions are far less likely to be concerned with the technical day-to-day aspects of database management. Instead, they are strategic-level senior management positions within the ICT department, and often head large, multi-site teams of DBAs. Nevertheless, most senior database managers begin their careers as techie DBAs, tinkering with and learning the various aspects of databases and database management.
Such data lakes lead to disconnected data producers, impatient data consumers, and worse of all, a backlogged data team struggling to keep pace with the demands of the business. Instead, domain-oriented data architectures, like data meshes, give teams the best of both worlds: a centralized database (or a distributed data lake) with domains (or business areas) responsible for handling their own pipelines. As Zhamak argues, data architectures can be most easily scaled by being broken down into smaller, domain-oriented components. 2b1af7f3a8
