Access to and from a VNet is controlled via Network Security Groups (NSGs), which act similar to a firewall, permitting or denying traffic based on rules which use the standard five tuples approach. The five tuples are: NSG rules can be applied to inbound or outbound traffic on the VNet and are processed according to […]
Networking is the fundamental building block of pretty much all IT solutions, but is often hard to appreciate due its transparent nature. If done right, networks offer easy integration and seamless flow of data, but it typically requires a lot of thought and design work up front.

Azure has a number of different storage services. The service is made up of different ‘layers’ shown below: The most important takeaways from the diagram above are the stream layer and the namespace. The stream layer handles the writing of data to the physical disks within the Azure datacentre, subject to the different type of […]
