MongoDB is one of the most widely adopted NoSQL databases in the world — and for good reason. Its flexible document model, high-throughput read/write performance, and native horizontal scalability make it the go-to backend for modern APIs, SaaS platforms, CRMs, e-commerce engines, and data-intensive applications. Unlike managed cloud database services, running MongoDB on your own […]
