With the release of SharePoint 2010, people started clamoring for app stores. Considering the requests, when SharePoint 2013 was released, it included app stores as well. Broadly, the store is of two varieties- public which is the primary store marketed by Microsoft and corporate which is a locked down, local store. For the apps, there are three broad categories:
SharePoint hosted- This app does not have any server-side components. Everything that is needed for the functioning like libraries, lists, etc are deployed within SharePoint environment.
Provider hosted- These apps have server side components and they are contained usually within ASP.NET applications to which separate environments must be provided for hosting them. SharePoint 2013 App Model serves as a great weapon for SharePoint developers due to the multitude of advantages that is offered to mainly the users. Administrators and third parties also reap benefits with their usage.
Cloud App Model- A Cloud App Model has been introduced, enabling the creation of apps. By virtue of the model, the apps are easy to use, install, upgrade, manage as well as remove. This can be used by hosted, cloud-based as well as on-premises environments, thus offering you a variety of options for hosting the app. Your very own web stack can be chosen as well.
Isolated apps- This feature is perfect for those people who worry about security. Here, isolation is used by the app model so that the app can be separated from main domain. Apps are deployed in their domain to their website, which protects further from unauthorized access to sensitive data. By virtue of this, on-premises environments that want to utilize Public SharePoint Store can be adopted; in fact, it helps drive the adoption process. They cannot offer total security but they do protect from certain breaches.
Familiar but flexible web experience- SharePoint websites and apps have same user experience but they are a lot more flexible, fitting seamlessly into SharePoint websites in various ways like as webpage’s part, as full-page immersive experience and custom actions of UI by extension of menus and ribbons.
App integration for Office- SharePoint Applicationss can be integrated with Office apps that are based on Office 2013’s web-based extensibility model. SharePoint Apps may be Office 2013 document template’s part.
Application lifecycle- The app lifecycle here is very user-friendly, with users being able to add as well as update apps by their selves. Additionally, when an update to app is released by a developer, users get notification about the existing update and accordingly they can decide whether and when the upgrading may be done. If the user does not want to use the app, then they can simply uninstall the app’s instance along with all related data getting deleted by that.
SharePoint apps are loved by users as they are offered easy ways for addition of new functionality to the entire system used by them. For the system administrators, control is the biggest advantage that they get. Operating topically managed locked-down store allows them to offer additional functionality to their users with full belief in the pre-approved apps. Central store indicates best use of advertising as well as marketing efforts for the third parties. In each case, it is a win-win situation. Great scope is offered for future development as well as growth which will no doubt attract developers, opening up several possibilities. Custom SharePoint development teams can help you build projects within allocated budgets and time schedules.
