HCIA-Cloud Service study guide
HCIA-Cloud Service · Work through your exam, one topic at a time.
The HCIA-Cloud Service credential (also written out as Huawei Certified ICT Associate – Cloud Service) is an associate-level certification track in the Huawei certification family, which appears on Huawei's training and certification pages alongside Free ICT Courses, ICT Academy and Huawei Certification. This independent study page is written for candidates who want a structured map of the exam's published domain structure before they begin preparing. It is aimed at early-career cloud engineers, system administrators moving into public cloud, pre-sales and support staff, and students who want a vendor-specific credential as a first step toward more advanced cloud certifications. The exam is organised into five domains of equal weight: Huawei Cloud fundamentals and cloud service overview; compute services (ECS, AS, IMS); storage services (OBS, EVS, SFS); networking services (VPC, EIP, ELB); and security, management and operations services. The HCIA-Cloud Service study guide has 5 sections and about 1,412 words.
