Becoming a certified cloud solutions architect is simpler than you might think. Despite the differences among cloud providers, their core architectures share many similarities, and the services required for certification follow a consistent pattern. In this guide, I’ll walk you through the process and highlight the benefits of mastering these key services in a vendor-agnostic manner as you work toward becoming a certified cloud solutions software architect. On this journey, we will cover the key categories that every cloud service addresses: Compute, Networking, Storage, Monitoring, and Security. The cloud: Public clouds are essentially collections of servers distributed across various regions around the world, allowing customers to leverage hardware infrastructure without owning it. In contrast, private clouds—often referred to as on-premises solutions—are maintained and managed by the company itself. The hybrid model combines the benefits of both approaches. The most significant bein...

The HashiCorp Certified: Terraform Associate (003) is completed; let's discuss it. The platform is the PSA, the same as for the Linux Foundation, and the exam is only one hour long, consisting of multiple-choice questions and a few where you need to write the answers. The exam itself is pretty straightforward. The verification process before the exam takes up more time than the exam itself. The questions are basic, covering Terraform behavior and conventions. There are some questions about infrastructure as code, but nothing too special. Like many exams, there are a few questions that seem a bit dubious, and the answers may not always make perfect sense, but choosing the option that feels "more correct" tends to work. The platform for scheduling is a bit confusing; you need to log in with your GitHub account and coordinate with the company where you work. In conclusion, it is a simple exam, and let's see if it brings about any changes in our lives.

Recently, I obtained the PSM I (Professional Scrum Master I) and the PSD I (Professional Scrum Developer I) certifications from scrum.org (Is there any website other than this one that is credible when discussing Scrum?). The exam experience has been the best so far because it is not proctored; you simply open your browser and answer the questions. While this simplicity is appealing, it also makes it quite easy to cheat, especially with limitless online resources available (like AI). As I mentioned in my previous thoughts on certifications, this lack of security diminishes their real value for me. The PSD I certification is arguably the easiest one I've ever achieved in my life. It's surprisingly straightforward, and you have ample time to tackle the questions. On the other hand, the PSM I and some of the others seem to align more closely with scrum.org's original intent, posing a bit more challenge due to the time constraints relative to question complexity. The rationale ...

After a lot of posts about certification, some people began to ask me, what is worth, what the path to take and things like that, so let's talk about that. I will try to bring a vision as a certified developer and as an interviewer for companies, and remembering, this is MY OPINION. One day a friend of mine said, "certifications are like zombies; you can survive against one or two, but when a lot of start to appear, it becomes an apocalypse." Well, the idea behind this phrase is that to really become a significant difference in your curriculum, you have to have a lot, and I really agree about it. We know that from time to time some certifications become free, and a lot of people get them, so it's normal to see the real value decrease. So the one who has a lot of different certifications shows that they have a real goal. But, let's analyze some points. As a developer, it's really nice to have the idea of something that "validates" your knowledge about...
