ACE-Professional study guide
ACE-Professional · Work through your exam, one topic at a time.
ACE Professional is a professional-level certification for people who design, build, and operate workloads on a cloud platform. It is aimed at engineers and architects with hands-on experience who want independent validation of their judgment across the full lifecycle: choosing an architecture, deploying compute and application services, managing data, wiring up connectivity, enforcing identity and compliance, and running the estate economically. The ACE-Professional study guide has 6 sections and about 1,640 words.
01Cloud Concepts and Architecture
Alibaba Cloud's global infrastructure is organized as regions (geographic areas) containing zones (isolated datacenters with independent power and network). A region is chosen for latency, data-residency/compliance, and service availability; zones within a region are chosen for high availability.
296 words, about 1 min02Compute and Application Services
ECS instances come in families tuned for compute, memory, or general purpose, plus GPU/heterogeneous options. Know instance attributes: vCPU/memory ratio, network bandwidth, and whether the family is burstable.
278 words, about 1 min03Storage and Data Management
Alibaba Cloud storage splits into object (OSS), block (cloud disks/ESSD attached to ECS), and file (NAS). OSS uses buckets and objects with storage classes (standard, infrequent access, archive) and lifecycle rules to transition or expire data.
291 words, about 1 min04Networking and Connectivity
A VPC is your isolated virtual network with a CIDR block, divided into vSwitches (subnets) bound to zones. Route tables direct traffic; security groups are stateful instance-level firewalls, while network ACLs are subnet-level and stateless.
261 words, about 1 min05Security, Identity, and Compliance
RAM (Resource Access Management) is the identity service: users, groups, and roles with policies granting least privilege. Roles are preferred for services and cross-account access over long-term access keys.
257 words, about 1 min06Operations, Monitoring, and Cost Management
Operational excellence relies on CloudMonitor for metrics, alarms, and dashboards, plus log collection for troubleshooting. Define alarms on key signals (CPU, memory where available, disk, latency) and route notifications.
