Before writing this course review, I would like to clarify that I have no affiliation whatsoever with the CloudNet@ team. I had been working as a network security engineer, and while studying AWS and Kubernetes on my own because I needed to know them for work, I came to learn about the CloudNet@ team through Inflearn. The certifications I have obtained so far include CCNA, CCNP, CISSP, and AWS Solutions Architect Associate. Before taking this course, I was able to use AWS to design VPCs, implement a 3-tier (WEB-WAS-DB) architecture, and integrate Route 53 and Cloud Front. However, after taking this course, I was able to go further and additionally configure not only WAF (Web Application Firewall) policies, but also KMS, Secrect Manager, CloudWatch, CloudTrail, Config, GuardDuty, and more, which was very helpful. I also found it quite useful to learn about Teleport, a server access control solution, through this course. To praise the CloudNet@ team, they provide the technology stacks they know through Inflearn at a reasonable price with unlimited access. The course quality is excellent, the presentations are clean and well organized with PPTs, the presenters’ voices are calm, and the subtitles are carefully prepared with spelling and spacing in mind. Personally, I am a fan of this team. ^^ My hope is that the members of this team will continue to take good care of their health so that I can keep enjoying new CloudNet@ team courses and books in the future. CloudNet@ team, thank you for providing such excellent courses and books. I look forward to continuing to see you through Inflearn. ^^
