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 Oracle has released new functionality regarding subnets, regional subnets. Earlier each subnet was tied in…
Series – Get your database running with Terraform part 6: Security Lists
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 another one for public subnet. Security lists can have have multiple rules in them and…
Series – Get your database running with Terraform part 5: Route Tables
Now when we have created IGW and NAT GW on previous post it’s time to create route tables which will send traffic outside from your VCN to the destination you require. It can be for example to your on-premise network (via DRG) or to object storage (via Service GW). Or it can be towards public…
Series – Get your database running with Terraform part 4: IGW and NAT GW
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 Internet depending on what traffic you allow through your security lists. If you use an…
Series – Get your database running with Terraform part 3: VCN
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 your network resources together. You can read part 2 from here. VCN is relatively simple…
Setting up network for e-Business Suite in Oracle Cloud Infrastructure
Setting up network for e-Business Suite in Oracle Cloud Infrastructure This post will be on how we did setup our network when the requirement was to deploy one Exadata and several application servers for our test environments. I’ll go through each components and then what was the setup on Terraform to get everything up and…
Oracle Cloud Infrastructure and provisioning Exadata part 1
One of the biggest reasons we started to use Oracle Cloud Infrastructure was that we could get Exadata provisioned for our use. We already had on-premise setup but to get similar setup in the cloud was important. I’m going to write a two part series on provisioning Exadata. On this first part I’ll discuss on…
ODC Appreciation Day: Terraform
First time I’m taking part of Oracle Development Community Appreciation Day which Tim Hall has created to post about technology you use daily. My topic will be Terraform which is still fairly new technology for me after having used it only for around a year now. But what a game changer it has been! I…
OCI block volumes and Terraform
So we already know how to spin up instances with and without Terraform but what about when you need to attach a block volume to your fresh instance which you’ve created? You have an option to login to console and just add either paravirtualized or iscsi volume to your compute instance. If you add paravirtualized…
Should I use tags in Oracle Cloud Infrastructure?
In Oracle Cloud Infrastructure you have two options to tag your resources, defined tags which are setup by your administrator or free form tags which can be applied by any user who has access to a resource. So why should you tag resources? In my opinion when you start your OCI project this is definitely…
