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.

I have had my Microsoft/Azure certifications for a while, but I completely forgot to write about them. So, after some requests, let's gain a real understanding of them. To be honest, I have mixed feelings about these certifications. Some of them are quite interesting, while others are less appealing. Certifications that rely solely on multiple-choice questions, step ordering, or something of that nature (where the answer is readily available in the options) don't sit well with me. In contrast to the Node.js and Kubernetes certifications, which involve hands-on tasks, Microsoft's certifications seem to serve more as decoration; practical knowledge isn't necessarily a requirement. The primary issue with this type of exam is that it doesn't effectively validate whether the certificate holder truly possesses knowledge of the subject. This is especially evident when we consider the existence of black market exam dumps, but that's a topic for another article. Exams ...

I got every Kubernetes certification in the last months, and as I said at the Node.js certifications , the Linux Foundation certification it is nice because they are practical, you must test your hands-on knowledge. Kubernetes and Cloud Native Associate (KCNA) This is the first one and the easier, it is the only that is multiple choice and cover the foundation knowledge about cloud, containers, etc. To be real, it really not worth waste time and money to get that. Certified Kubernetes Application Developer (CKAD) If you are already a developer, that works with a Kubernetes and you have access and permissions to create resources that are important to a day-to-day for microservices, this is a pretty simple one. Basically, test your knowledge to containerize applications and create all necessaries of things to put online, like deployments, etc. Certified Kubernetes Administrator (CKA)  Here the thing start to be a little complicated, you must have a good knowledge about linux, and oth...
