Everyone acts like being locked into a provider is the worst thing that could happen. When it comes to monitoring, if I'm using other AWS products, I don't mind being locked into AWS monitoring as well. Because I'm either going to just use it and be done with it, or I'm going to spend months and lots more money finding a non-AWS solution that integrates as well with AWS. If we ever switch away from AWS, I'll invest the time then to use a new product, but until then, we accept the trade-off for saving lots of time and money.
