Not a lot of people are clear on this, but SaaS and cloud-based solutions are two different things. It is a little confusing, because they are both essentially “cloud-based,” considering that they exist in the cloud. However, they are not the same, and perceiving them as the same will blur your understanding of how they work separately.
Where a SaaS WMS would be on a shared infrastructure, a cloud-based WMS would exist on a privately hosted server. This is the key difference! Keep in mind that because of this, a SaaS is a lot more affordable option whereas a cloud-based solution requires a slightly larger investment. Not only that, but SaaS is easier to implement and does not take much time, whereas cloud-based software would take more time to implement.
