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.…
Oracle introduced Cloud Guard some time ago to OCI, in this post I’ll take a brief look what Cloud Guard is and how you can get notified on unwanted changes in your tenancy. As an example, I have a public…
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.…
Earlier this week I took the 1Z0-997 Oracle Cloud Infrastructure 2019 Certified Architect Professional. In this post I’ll try to share on how I studied on the test and what areas I feel helped me on passing the certification. I…
Now we have everything else setup on the network side apart from subnets. Subnets are continuous IP address blocks which don’t overlap with any other subnet IP address block in your VCN. Things to remember: As time of writing this…
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…
Now after we have compartment where to place resources we are ready to create Virtual Cloud Network (VCN). Since previous post was about compartments and how they logically group your resources one way to think is that a VCN groups…
