I’ve been a big fan of Terraform for quite some time but one of the things I have been complaining about has been some things which have not been possible when you use Terraform modules. Why do we use modules? It gives us a way to reuse our code so that each resource creation is…
Use OCI Notification Service to get informed on your Autonomous Database scaling events
This post will be mainly about Oracle Cloud Infrastructure Notification Service, the Autonomous Database scaling is just used to demonstrate what you can do with the notification service. So what is Notification Service? It’s a service where you can create different topics where you publish messages to set of subscribers. Depending on your configuration you…
Security in Oracle Cloud Infrastructure and why you should care less about it
I recently attended Accenture’s Oracle leadership council and was asked to speak about Oracle Cloud Infrastructure security. I’ve said that I’m definitely not an expert on security and that’s why the subject was actually a cool one to speak about! If you’ve used any of the major cloud providers (Azure, AWS, GCP) you know the…
Oracle Cloud Infrastructure and Dynamic Groups – what are they?
You might have seen dynamic groups mentioned when browsing through OCI console or when you’ve read the documentation. One of the most important things when creating services is handling access to specific services so that your access keys are not compromised. This is one neat way of managing that in the cloud. Instead of storing…
Taking a ride with OCI autoscaling and instance pools
Some time ago Oracle Cloud Infrastructure introduced features around autoscaling and instance pools. This in short means you have an instance pool which uses image from the instance configuration you have defined. Instance pool has minimum number of instances you want to keep running and with autoscaling you can add scaling out or in depending…
Series – Get your database running with Terraform part 10: Summary
My idea on writing this guide was to provide overview what components you need when you create a database in Oracle Cloud Infrastructure. Even thought there are several components once you do it few times you get an understanding what you need and it comes a breeze to create these. Most issues I have seen…
Series – Get your database running with Terraform part 9: Database
At this point I have created everything else apart from the database. For the database we have few options starting if we would like to have Baremetal, Virtual Machine or Exadata. In this demo I’m going to create VM single-node database but I could create it as RAC database as well with two nodes. Similar…
Series – Get your database running with Terraform part 8: Compute
Before creating database I will create jump host on public subnet so we will be able to access our database once it’s created. If I would have connection setup to our corporate network I could access the private subnet directly if my network configuration would allow it. This way I can limit the surface on…
Series – Get your database running with Terraform part 7: Subnets
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…
