Cross-region DataGuard in OCI coded with Terraform

In one of the latest lessons of my tutorial I have shown how to setup DataGuard locally within the same region. I guess this is some sort of database protection, but in case of the whole region failure it will not help at all. So it is worth to consider the cross-region solution for database security. In this additional lesson I am trying to showcase how to deploy remote DataGuard Association with the usage of Terraform code.

The database archivelogs will be send directly via DRGs and OCI backbone. I hope you will find this dish tasty and it will be somehow useful for your work with the cloud solutions. Let me know if you have any kind of feedback. 🙂

Bon Appetit,

Feedback loop.

linkedin_groupThe last two months, during the COVID thing, were transformational for this blog. Someone can say the window of the opportunity has been opened by free training and certifications for OCI. Many of us have decided to ride this horse and discover OCI, in-depth. Some of us have reached the highest professional level, some of us are still on the associate one. No matter if you plan to be OCI Architect, OCI Developer, or maybe OCI Ops, there is a lot of work in front of us. It will be a permanent learning cycle.  This is characteristic of the modern cloud world. New features, new services, new knowledge to be discovered and explored. Frankly speaking sometimes I feel overwhelmed, by this massive amount of “new stuff”. I believe you have this feeling too. And here comes the community. That is why I have built a community group on LinkedIn to exchange knowledge. Someone can say it is just another channel to promote this blog, but believe me – my goal has been simple, build the place to exchange knowledge. As much as possible … people who are satisfied with answers… people able to find some form of support from the others. A feedback loop is crucial. Without a feedback loop,  the community doesn’t exist. So I really encourage everyone to ask questions and the others to share the experience in response.

BTW. Many of you are asking how to help, support our blog, YT channel, and LinkedIn group. You can join us to be the next cook in the kitchen (don’t be afraid, this kitchen is extremely big and there is a lot of space to work). Another option is to donate us (check up on the right). If you want to be just a reader of the blog or watcher on YT, I think it is  absolutely OK 🙂 But remember about the feedback loop. If you haven’t subscribed to the channel, please do it now. You can also give us feedback on Linkedin with your likes 🙂

Best,

How to build microservice which is based on OCI Function and ATP with Terraform

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.

I have used the code related to this blog post and I have refactored it a bit. The idea behind was to eliminate VM-based web server with Flask microservice. This old school technology could be replaced by OCI Function and API Gateway (btw. check Kranthi blog post). I guess this refactoring has been pretty successful. Below in this 15 minutes video, you will see my hard work on this topic. Hope it will be tasty 🙂

Bon Appetit,
