To begin with, one has to admit that there is slight difference between web and cloud applications but when the difference is in two technologies then even the slightest difference matters a lot. Essentially, every cloud application is a web application but the converse is not true. However, both web and cloud apps require internet to function. Despite the similarities, there are significant differences between the two app platforms.
The basic difference which must be addressed at the very outset is on the basis of tenancy. The cloud applications have a multi-tenancy while the web applications have an isolated-tenancy. This means that the single instance of cloud apps can cater to multiple users at a time. The users can customise some parts of the cloud application but it won’t affect the code whereas a web application has isolated-tenancy that caters to only one user and his customisation requirements.
The core difference between cloud and web app lies on dependence i.e. the web applications are dependent on web browsers while the cloud applications are not. In order to run a web application you’ll require a web server whereas cloud apps can run on either user’s computing device or web server. The cloud apps can be installed on either a public or a private cloud while the web apps are either installed on Internet or Intranet. There are a lot of cloud iot solution provider available in the market who solve a lot of issues.
Most of the computer cycles happen at the single data centre in a cloud application but in the web application they happen at multiple data centres though you can access it from anywhere. Cloud Applications have their user data and business processes stored in multiple replicated data centres contrasting with the web applications, where the data is stored in a single data centre.
Customisation & Functionality
Undoubtedly, the cloud apps offer more customisation options and wider range of functionality. The web application have on the contrary limited functionality and customisation. The cloud applications are standardised for all users and each user can customise them according to their whims and fancies. The web applications on the other hand are specifically customised with respect to a user.
Availability & Scalability
A web application has limited availability & scalability while a cloud app is inherently scalable and has very high uptime. This means that a cloud app has the possibility to be used in a range of capabilities while in case of a web app it is limited. High uptime of cloud platforms signify that they are working and available unlike the web applications in comparison.
Hence, there is slight yet enough difference in the platforms that makes a significant difference. When choosing for an application platform the key factors that make a difference are mentioned above so that you choose the one that best fits your requirement. Cloud apps definitely are winning the battle over web apps, though if you are planning to use only for yourself with specific set of features that you have in mind then they’re perfect for you.
