Software as a service
Saas (software as a service) is a cooperation model with business customers, which is based on delivering software localised on a cloud, so it can be available anywhere, on any device with access to the internet.
If users want to exploit the functions of a shared business application, they just have to open it in a web browser. More and more people assume this solution as the most viable, mainly thanks to low periodic fees, which are not apparent to company’s budget, as well as the lack of long-lasting period of implementation. Saas solution permits immediate access to application’s functions, thanks to the available trial version during the test period. Another key Saas advantage is the possibility of using advanced applications, without the need to install or maintain hardware or software.
Saas vs On Premises
Saas model is opposite to traditional On Premises model, which demands buying accurate tools located on media and their subsequent installation on particular devices exploited by the users. Such purchase involves one-time payment, which may vary from few to several thousand pounds. Not every enterprise can afford such a sum, so more and more companies prefer Saas, where the initial fee is relatively lower and further cost of subscription is proportional to the level of resource consumption. It means that the payment is adequate to the number of users exploiting the shared application.
Another asset of Saas is the fact that the amount of application users is typically infinite. The length of subscription period depends on the conditions of contract signed between the client and the performer. Saas solution may appear more profitable also because of the fact that the whole software is localised on the side of the performer. This means that the software house is responsible for software’s infrastructure, update, security, creation and restoration of backup copies of files and database in case of a breakdown. Therefore there’s no need to worry about lack of access to the data or their complete loss. The users may also count on technical support within the software service, which is really helpful and time-saving. Because of this your company doesn't need to hire any additional IT specialists.
Despite the fact that Saas is definitely the most common and popular solution at this moment, it has its opponents. They acknowledge that this model is unstable, since the work of software is dependent on settlement of periodical subscription. Whereas the traditional business model guarantees unlimited access to purchased application. Moreover they highlight that cloud-based files are more vulnerable to undesirable activities of third parties. Despite that the producers of cloud-based solutions ensure strong securities, which forbid data breach, some entrepreneurs prefer to manage and protect sensitive data by themselves.
Another argument for On Premises is bigger control on the side of the software owner, not its creator. It refers also to the level of possible interference with software. In other words On Premises solution provides more opportunities in customising and personalising the software according to individual needs of the client.
Which solution is better?
As always before you make a final decision you have to think about particular needs of your business. If your company is still expanding, it’s worth choosing innovative methods, which for a small charge will give you fast access to the application, which is user-friendly and doesn’t require advanced technical knowledge.
Saas solution will also increase the mobility of your employees, who will be able to access the application on each device connected to the internet. On the other hand, if you don’t want to rely on external dimensions, like functional internet connection, but you demand thorough customisation and exclusive control over the software, you should lean towards the traditional On Premises method.
