The future of software is moving towards applications that run inside your web browser.
Web-based applications remove the hassle of ever having to update your business software again. It also means that developers can react quickly to issues that arise and release new versions far quicker than traditional software vendors could ever manage.
It can be annoying and time-consuming when software on your computer has to regularly download updates from the Internet in order to keep you up-to-date with the latest version. Often you must reboot your computer after installation and there is no guarantee that you will not face problems with the latest update, in which case you will have to wait for the next patch.
SaaS (Software-as-a-Service) eliminates this hassle and this is why it is becoming the technology of choice for enterprises of all sizes who need to check their email, store files and work on their business accounts with the minimum amount of hassle.
