Overview of scaling types supported in Bluemix
Building scalable applications has become the de facto standard for modern web applications. Applications need to be built to scale. Scaling of applications is required when there is a need to meet increased activity within the application. Applications that scale are highly available and responsive to requests. There are two types of scaling, as follows:
Vertical scaling
Horizontal scaling
Vertical scaling
When applications are deployed, they use compute resources to run. These compute resources are:
CPU (processing)
RAM (memory)
Scaling applications by increasing the resources available to them in the same machine or physical node is called vertical scaling; this is also known as scaling up. This method of scaling is useful for applications that are designed and developed in such a way that they cannot share state or data. Less modular applications, or applications with more tightly coupled modules, usually have a need to scale within the same node...
