Currently, we are using WordPress in the organisation to deliver content externally to clients via a portal. However, we have installed way too many plugins for our liking, and they are starting to conflict with one another. Also, there were issues around scalability in the way we initially designed it. A few people in the organisation are leaning toward a Microsoft SharePoint solution using Livetiles, but we've been told it is mainly geared towards internal/intranet solutions as opposed to external solutions (which we provide). I was wondering if anyone has some high-level thoughts to share in regards to moving to a Microsoft Sharepoint environment vs. a more flexible solution like Umbraco.
I am not sure if I can recommend one or the other without knowing your exact needs and what plugins you are using. Is this just a company publicity website, or more of a web application with login functionality and a store?
But, Sharepoint doesn't seem like the best solution in my point of view for a public-facing website.
You might want to read this article from Microsoft about SharePoint external public facing sites. SharePoint is geared to internal sites. WordPress sounds like a better option for you. I don’t know anything about Umbraco.
Hope this helps, Yvette
