Cloud data strategies are crucial in preventing "data black holes" in the cloud, where massive amounts of data accumulate and become difficult to move or utilize. Data gravity is a concept that describes how data behaves like a celestial object with mass, attracting applications and services into the same environment. As data grows, it becomes harder to move, leading to vendor lock-in and reduced flexibility. To overcome this, organizations need to use a database that runs the same in any environment, such as MongoDB, which combines flexibility with consistency across different environments, including on-premises and cloud deployments.
