Life is unpredictable, there's always a "must" and should "scenario", this frequently happens in businesses, as such having a server will provide some use.
The first question to ask yourself is "What are the goals behind this business and what is the end game?" This will affect whether or not the traditional on-premise server meets the requirement.
In a company multiple devices are in use as such, it would often be disorganized. All devices containing sensitive data from small to large ones how are you able to be certain they are all secure? Controlling the logins? Enforcing strict password policies?
Keeping everything organized by having a server could be considered as any business with multiple employees is recommended to have a server of some sort whether it is cloud or on-premise.
Servers are ultimately the heart of the IT infrastructure that stores and access data. There are multiple factors that contribute to successful growth. But servers are the main contributor to its success. This is due to the benefits it brings such as:
Servers are the foundation of every business. Unlike an interlinked network connection where if one PC fails the entire system goes down till the problems are identified and resolved. A server is able to maintain its redundant hardware to prevent these issues. This could be said that the failure of a single device won’t guarantee the failure of the entire system. Thus the business operation is able to continue even in such circumstances.
Backups are really important as they hold the building blocks behind your business. If everything is configured and backed up the scenario of data loss is most likely prevented. The server will most likely follow the company throughout the companies lifespan as such choosing a suitable server is the right way to go to ensure backed up data is never lost.
File access restriction controls are commonly found in a server. This restricts who and what they are allowed or able to access the collective data in the server. But this is not all as it also provides the privating of documents, sharing documents, providing read-only documentations and etc.
Servers are commonly known to have faster components which contribute to the distribution of data more quickly even to multiple places.
Antivirus system is a necessity for businesses these days as it is a defense mechanism to face viruses and spyware. Through the server system, the corresponding system administrator is able to deploy anti-virus software from a single PC to multiple PC connected to the network to execute network-wide scans to identify and remove any sort of viruses.
