Cloud computing is complex and new to many organisations. Microsoft is very aware of this and the concerns that organisations have. For this reason, they have specifically designed their cloud services to maximise reliability and minimise any negative effects if things go wrong.
Built-in resilience and recovery is based on several assumptions – the main one being that at some point either the underlying infrastructure or the processes will fail. No matter how prepared you are, there is always a risk that hardware will fail, humans will make mistakes or software will have bugs. Since the move to cloud computing developers have a very different approach to deal with such occurrences.
We know that once you have moved to the cloud you expect continuous innovation from Microsoft without compromising quality, and this is one of the reasons why Microsoft have built their services and software with resiliency and recoverability in mind.
