MongoDB to Acquire Realm

So the big news this week is obviously the announcement of the acquisition of Realm by MongoDB. As you might expect, both sides are putting a positive spin on things but with similar MBaaS services disappearing (or at least pivoting) following similar acquisitions in recent years and a selling price for Realm that is reportedly less than it’s funding , it doesn’t sound like everthhings as rosy as it may seem. In this case though I really hope I’m wrong as in my experience, Realm’s technology works really well and is a great alternative to first-party solutions such as CloudKit. realm.io
