The latency between two servers located in two regions is normally higher than the latency between two servers located in the same data center or the same rack. High latency between application servers has a direct impact on the overall performance of the application. By placing applications servers in the same physical location, we can reduce the latency. When it comes to Azure VMs, we can…
Virtual Machine Snapshots are the quickest way to recover a virtual machine from a disaster. Snapshot is a copy of the virtual machines’ disk file at a given point of time. There are situations where we may need to get certain data out from snapshot without restoring a complete virtual machine. The best way to do that is to create a virtual machine from the snapshot and then retrieve the…
I have a web server running in my on-premises network. I like to allow access to it from the internet via TCP port 443. To do that, I need to create two types of rules in my edge firewall. I need a NAT (Network Address Translation) rule to map a public IP address to the private IP address of the webserver. I also need an ACL rule to allow only relevant traffic (TCP 443). This ensures the traffic…
When we connect two networks via VPN connection, we only allow certain traffic to pass through (In most scenarios). This is the normal security best practice. We normally use a firewall to do this. When it comes to Azure, we may also need to connect virtual networks . In such situation, By using Azure Firewall, we can control the traffic between virtual networks. More info about Azure firewall…
