Key differences between on-premise and cloud-based access control

The terms “on-premise” and “cloud-based” are often used when talking about data management and data security. These concepts are very much fundamental and are perhaps one of the first considerations when it comes to planning out an access control system. In this guide, we will talk about the basics of how these two systems differ from each other. At the end of this text, we will also tell you which one is better overall.

If you already know what these terms mean, then we have some recommendations for you. One of our top suggestions when it comes to access control solutions is Swiftlane. Visit their website now and check out their one-stop-shop for cloud-based access control systems.

Data Storage

The main difference between on-premise and cloud-based systems is the way data and information is kept. Essentially, in an on-premise setup, data is stored in a physical storage unit. Typically, this storage unit is made up of a series of harddrives and other storage devices. This entire setup is often referred to as a local server. Local servers are owned and maintained by the original users. In contrast, cloud-based systems involve the use of the internet as a means to store data and information. In a cloud-based access control system, users do away with having to use physical storage devices. Instead, data is uploaded to the “cloud”. This setup is what’s commonly called a cloud server. In a cloud server, users are merely renting storage space from cloud storage providers. Essentially, the responsibility of maintaining cloud servers is carried by the providers and the users are just given access to their section of the storage space, which they can freely manipulate to organize and retrieve files.

Are Cloud-Based Systems Safe?

One might mistakenly think that cloud-based systems are inherently more risky because users do not own and maintain the data. However, when you think of the bigger picture, it is actually a much more efficient and effective setup in relation to data security. First, since the responsibility of maintaining the server is held by the providers, there exists a degree of liability. This means that providers are constantly driven to keep their servers at optimum performance so as to prevent data theft, data corruption, and data loss. Because owners do not handle this responsibility, they clear themselves of the pressure as well as costs of having to do this task while simultaneously keeping track of their business operation. Secondly, cloud service providers do specialized work. What this means is that they have access to all the specialized tools, techniques, and strategies to effectively maintain and take care of data. Not all businesses have access to these things and so it might be very difficult to keep data safe and secure at the local scale. Finally, improvement incentive is greater for cloud service providers. Some national governments have already started to work with well-established cloud service companies in an attempt to boost the integration and centralization of data storage. This is also done to properly oversee the operations of such cloud service companies. Ultimately, this only increases the quality of service work and it reverts to the benefits of individual users.

Are Cloud-Based Systems Expensive?

As regards costs and expenses, both cloud-based and on-site solutions have their own unique cost drivers, which can make them independently more expensive than the other. For example, on-site storage will entail more frequent and more complex maintenance, which can quickly add up over time. In contrast, cloud servers require users to pay subscription fees for continuous usage. Yes, cloud-based systems could be expensive. But we have to keep in mind long-run costs as well. Having said that, cloud-based systems are more cost-efficient because subscription fees are generally more affordable than equipment maintenance.

With all of that said, it is rather clear that cloud-based systems are preferable. In a cloud-based solution, you get better security, better scalability, high degree of liability, cheaper operational costs, and convenience, which makes it a better value for owners and investors.
