SharePoint 2013 & Microsoft AppFabric 1.1 support
Reference
Microsoft AppFabric 1.1 for Windows Server Ends Support 4/2/2016“. SharePoint 2013 uses Microsoft AppFabric 1.1, and this means support for SharePoint will also be effected.
Background
AppFabric provides hosting, management and caching capabilities for Web applications and middle-tier services. This application helps us to build, scale and manage applications, in particular those built using ASP.NET, Windows Communication Foundation (WCF) and Windows Workflow Foundation (WF).
Microsoft has recommended all applications using AppFabric 1.1 for Windows Server to migrate off this technology by April 2, 2016.
Azure Redis Cache is was build on the popular open source Redis Cache. It provies you access to a secure, dedicated Redis cache, managed and fully supported by Microsoft, so you can focus on your application rather than the infrastructure. We recommend all Microsoft AppFabric customers using Cache to move to Microsoft Azure Redis Cache.
SharePoint 2013 leverages Workflow Manager and an internal workflow hosting for legacy workflows.
SharePoint functionality (including the Distributed Cache feature) will be supported under the Microsoft Support lifecycle for SharePoint 2013.
Another important point to consider that the next version of SharePoint which is suppose to be SharePoint 2016 will integrate with Azure Redis.
