NHN Cloud Associate case studies

NHN Cloud Associate · Put your knowledge to work in context.

The NHN Cloud Associate credential is aimed at cloud engineers, platform operators, and solution architects who work with NHN Cloud's integrated cloud service portfolio. NHN Cloud describes itself as a cloud platform offering compute, container, network, storage, database, monitoring, hybrid and private cloud, game, security, content delivery, notification, AI, machine learning, application, search, data and analytics, dev tools, management, bill, collaboration, contact center, and governance and audit service categories. Candidates should be comfortable with core infrastructure concepts and with the service names and purposes that appear in the NHN Cloud catalog, because the exam domains - Compute, Container, Network, Storage, and Database - map directly onto that catalog. For example, the Compute category lists Instance, GPU Instance, Cloud Functions, Instance Template, Image, Image Builder, Auto Scale, and Virtual Desktop; the Container category lists NHN Kubernetes Service (NKS), NHN Container Registry (NCR), and NHN Container Service (NCS); the Network category spans VPC, Network Interface, Flow Log, Floating IP, Network ACL, Security Groups, Load Balancer, Load Balancer (DSR), NAT Instance, Transit Hub, Internet Gateway, Peering Gateway, Colocation Gateway, NAT Gateway, VPN Gateway, Service Gateway, Traffic Mirroring, Private DNS, DNS Plus, and Direct Connect; the Storage category covers Block Storage, NAS, NAS (offline), NAS for BigData, Object Storage, Backup, Data Transporter, and Storage Gateway; and the Database category includes RDS for MySQL, RDS for PostgreSQL, RDS for MariaDB, RDS for MS-SQL, EasyCache, the various DBMS Instances, and Database Migration Service.
