We often receive questions like:

“I want to start a career in Linux cloud computing — which certifications are actually useful?”

“Which certificates can help me systematically organize my knowledge?”

As a network engineer who has been working in cloud computing for years, let me break down the most recognized certifications in the industry, and share some exam-prep insights that aspiring candidates can use.

Vendor-Led Certifications: Learn by Platform, Apply at Work

These certifications are closely tied to specific cloud platforms.         

What you learn can be directly applied in real jobs, which makes them very practical.

• Red Hat RHCSA / RHCE

• RHCSA is the entry-level exam, covering Linux basics such as commands and system administration — essentially laying the foundation for cloud computing.

• RHCE goes deeper into service configuration and operations, like performance tuning and troubleshooting.

• Red Hat’s unique point: 100% hands-on exam.No multiple-choice memorization — you must solve real tasks.         

This is especially important in cloud computing, where solving problems in practice matters more than theory.

We provide RHCSA/RHCE Dumps so you can drill every key task before the exam.

• Public Cloud Certifications

• AWS: Certified SysOps Administrator — heavily focused on Linux usage in AWS, e.g., managing EC2 instances, configuring security groups, etc.

• Alibaba Cloud: ACP Cloud Computing Operations — focused on ECS, load balancing, and Linux-related operations.

• These are primarily written exams, but hands-on practice is essential.        

Reading docs alone can leave gaps in understanding.

Containers & Kubernetes Certifications: A Must in the Cloud-Native Era

In today’s cloud environments, containerized applications are everywhere — and related certifications are increasingly important.

• CNCF CKA (Certified Kubernetes Administrator)

• CKAD (Certified Kubernetes Application Developer)

Although the names don’t mention Linux, Kubernetes runs on Linux.        

Tasks like node maintenance or checking container logs all rely on Linux commands.

• CKA focuses on cluster deployment and troubleshooting.

• Many cloud-native teams at major companies now require these certifications for new hires.

Exam Prep & Selection Tips

• Don’t chase too many certifications.        

Choose based on your career direction:

• If you’ll focus on one public cloud provider, start with that vendor’s mid-level certification.

• If you want to work with open-source or hybrid cloud, go for Linux + open-source cloud certifications.

• Beginners should start with RHCSA or RHCE to build a solid Linux foundation before moving into cloud-native or advanced tracks.

Our Linux & Cloud Certification Dumps cover real exam-style questions, practice drills, helping you study more efficiently and improve pass rates.

Final Thoughts

Certifications are just milestones — real ability comes from project experience.         But the exam-prep process helps you systematically review and structure your knowledge, avoiding fragmented learning and missed key points.        

That is the true value of certifications.
