Today, we will explore how to tie those advanced techniques together. Those techniques might do different — sometimes opposite — things. Still, sometimes we need to use all of them, to cover all possibilities. So...

As applications grow in complexity and user base, the demands on their underlying databases increase significantly. Efficient database scaling becomes crucial to maintain performance, ensure reliability, and manage large volumes of data. Scaling a database effectively involves a combination of strategies that optimize both hardware and software resources...
