Scaling in or scaling up (also called vertical scaling) is a way of achieving scalability through the addition of more resources, such as memory or faster processors, to the same machine. This is not always applicable to all applications, as costing is also a factor when considering vertical scaling.

You can also upgrade your resources or hardware instead of adding new resources to your machine. For example, if you have 8 GB of RAM, you can upgrade it to 16 GB, and the same thing would be applicable for processors and other resources. Unfortunately, with upgrades in hardware, there is a limit to how much you can scale the machine. This may lead to simply shifting the bottleneck, rather than solving the real problem ...
