Traffic between Azure resources in a single region, or in multiple regions, stays in the Azure network—intra-Azure traffic doesn’t flow over the Internet. In Azure, traffic for virtual machine-to-virtual machine, storage, and SQL communication only traverses the Azure network, regardless of the source and destination Azure region. Inter-region virtual network-to-virtual network traffic also flows entirely across the Azure network.
With many other VPS plans, they cut off and limit your resource usage. Our Cloud VPS plans are different in the sense that they offer Burstable RAM limits. You will have a dedicated amount of RAM during low traffic periods (1.5GB for Cloud VPS-1000, 3GB for Cloud VPS-2000 and 6GB for Cloud VPS-3000), but are able to use a higher amount during high traffic surges and spikes.
In terms of backups, databases and files, it all depends on the type of setup you choose. If you choose a server with a control panel it will make it effortless but if you want to do it manually, i suggest you take some time to learn how to do it properly, because, one error and you might loose everything you have worked for. My suggestion for a best server setup is a cloud managed cPanel VPS with SSD and good backup tool.
Unmetered hosting is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use ~3 TB on 10 Mbit/s or up to ~300 TB on a 1000 Mbit/s line per month, although in practice the values will be significantly less. In a virtual private server, this will be shared bandwidth and a fair usage policy should be involved. Unlimited hosting is also commonly marketed but generally limited by acceptable usage policies and terms of service. Offers of unlimited disk space and bandwidth are always false due to cost, carrier capacities and technological boundaries.
