As you might have seen, few weeks ago Oracle announced improved Dynamic Routing Gateway functionality which I was super excited about. Why? Previously when you’ve designed Transit Networking on OCI you’ve always had to use Hub & Spoke model for…
We looked on setting up Oracle DNS on part 1, and how you could manage different DNS options with Private Views or DNS listeners & forwarders. In this post I’m gonna look on what options we might have with Custom…
First of all, big thanks for my colleagues Rob and Travis for giving me some good ideas on this post! I usually recommend Transit Networking for most of the implementations as it provides security and scalability for your OCI infrastructure.…
This is the second part of my OCI Private DNS posts. You can read the first part from here. In this post I will extend my configuration to have two VCN’s which will be connected via Local Peering Gateways together.…
I’ve wanted to write something about this topic for quite a while and finally OCI has released it’s first step of Private DNS capabilities! Why do I think this is a big thing? For example let’s say you need to…
So a while back OCI got NSGs (Network Security Groups) but most what I still see with implementations is that people tend to use Security Lists. Remember Security Lists are applied on subnet level while NSGs are applied to VNICs.…
Before we can create the subnets we still need to create security lists. They will control what ingress and egress traffic will be allowed within subnets. I will create two security lists for this project, one for private subnet and…
Previous part three on creating VCN can be found from here. Now let’s start with basics. What are IGW and NAT GW. Internet Gateway (IGW) in OCI is the connection point which routes your VCN traffic from and to public…
