Cost-wise, VPS is slightly higher than shared hosting. However, in return, a client gets more resources, better flexibility, and reliability etc. When a business is still in a developing state, they do not require a dedicated server yet, since traffic is still low and they can manage with lower resources. Dedicated servers are more expensive and may not fit into the budget of an organization.
