A lot of people around the world believe the serverless approach is the ultimate future of cloud computing. I am also such a believer, but it will be a gradual move, sort of evolution within the next couple of years. Some time ago I have published a blog about private endpoints for ATP.
Last week I was very busy so it was hard to find a few free cycles to write about it. Yes, I have passed recently Oracle Cloud Infrastructure Developer 2020 Certified Associate exam. Frankly speaking, it was obvious for me I need to do it. I am a hardcore developer here at FoggyKitchen, mostly with Terraform, but I am also writing a lot of stuff in Ansible for Oracle, for example, Ansible-Database-Migration-Tool (ADMT). You are probably curious if this certification is important and if it is worth spending time on it. Well… I guess it is. The modern world is changing like crazy. Especially now during the COVID-19 outbreak, which transforms business in an extremely fast way. I have heard that recently some big CEO has told that staying away from the cloud today would be like planing to extinct soon. Maybe this is too radical for me, but it gives a sense of mindset shift and technological revolution we are approaching today. I am not sure how it looks like at your place, but in my location, in Poland, after full lockdown, all educational activities have been moved from analog to digital. The teachers must deliver e-schooling via Zoom or on the other platforms. On the other hand, the shops are adapting very quickly to provide a nice and easy e-commerce experience with the delivery of all goodies at your footsteps in your house. For example, I was shocked it wasn’t possible to buy new shoes in the mall for my kids (full lockdown means malls are closed). The spring has approached and their feet were just bigger. There were no excuses. I have done it via e-shop…
About the flexibility of ATP instances in OCI I have written so far two times. For the first time, it was just a short ride to show how it easy to create this autonomous database in OCI. For the second time, I have shown a new feature of ATP – Private Endpoint. It means ATP instance will be completely separated from the public Internet and visible exclusively in the private subnet. Today I will show you yet another feature of ATP. Now you can quickly clone ATP instance. You can do it in two different ways. The basic is just a clone from the existing instance. A more sophisticated clone is based on ATP automatic backups. In the video below you can watch both use-cases coded with Terraform. I hope it will be a tasty thing as previous recordings 🙂
It is not the first blog post about ATP, but I think this one is even more interesting. For your information, a few days back at OCI Release Notes webpage I have found information about new features for OCI Autonomous DB offering. I am talking about Private Endpoints for ATP or ADW databases. This feature has been awaited for a very long time. Previously your ATP or ADW databases were available only via public IPs. Now you can nest them inside a particular VCN and subnet. It means your database will be available under private IP enclosed in your subnet’s CIDR. Of course, you need to prepare some Network Security Groups (NSG) on ATP/ADW level and VM level. Since that moment VM can connect to ATP/ADW with SQLNet connection via private IP. For testing purposes I have created small GitHub repo and below you can find a video about how to use that repo. I believe you will find this dish very delicious. 🙂

More then a year ago in this post, I have initiated OCI ATP provisioning topic. After a year I have rewritten the whole repo. Not only because HCL 0.12 is a formal standard now, and all Terraform code was outdated. I have done it also because I feel it is good in general to re-test everything and verify how it works nowadays. On the other hand, after my last course for Terraform, I have found myself confident enough to record videos for blog posts like this one. That is why you can also find a short movie below. 🙂
