I'm setting up a simple hub-spoke configuration of VNets in Azure. Hub contains a VPN gateway then creating spokes for storage, compute etc. My main concern is latency so I'd rather not setup custom routing through the hub VNet.
Since the storage spoke will need to see the compute spoke, do I need to setup peering connections between the spokes or does Azure route through the hub VNet automatically?
We've got currently 2 Express Route Circuits ( 2 VCs on each ) with Public peering. Now, we have to provision the Express Route Circuits with same Service Keys due to some internal change and requirement from Network Dept. Will we able to get the ER circuits re-provisioned and keep the public peering or we need to use the MS peering without fearing that peering won't work ?
My organisation is in a position where we are paying quite excessive charges for single homed IP transit form our primary data centre provider. We're at the position now where we're ready to start thinking about switching to direct relationships with transit providers.
The question here goes touches on the subject slightly, but it's not very comprehensive. For example the accepted answer states Cogent and Hurricane Electric are considered cheap providers, whereas Level(3), AT&T, Telia are considered to be better. What it doesn't do is explain exactly why one provider may be better than another.
I am quite familiar with BGP, multihoming and the concept of peering and transit, however what I don't have is an understanding of why some of these providers would be better than others.
To be clear, I'm not asking for a suggestion for a provider, or any names mentioned for that matter. I'm more than happy to go off and do my own "shopping" research. I just have the problem that I need to compare apples to apples, and I don't know what to look for!
If it makes a difference, our organisation is in the UK.
Our organization is planning to peer with the local internet exchange, we are planning to obtain an AS number to allow us to do this. However I was unsure if we also need our own IP address space to get connectivity. Would anyone be able to clarify this?
