Alibaba ACP Cloud Computing study guide
Alibaba ACP Cloud Computing · Work through your exam, one topic at a time.
The Alibaba Cloud Certified Professional (ACP) Cloud Computing credential is a professional-level certification for engineers who design, deploy, and operate workloads on Alibaba Cloud. It suits cloud administrators, solutions architects, and DevOps or operations staff who already have hands-on exposure to core services and want formal recognition of practical competence. The Alibaba ACP Cloud Computing study guide has 9 sections and about 3,011 words.
01Cloud Computing Fundamentals and Alibaba Cloud Architecture
Alibaba Cloud organizes resources by region (geographic location) and zone (isolated datacenter within a region). A region is chosen for latency, compliance, and service availability; zones are chosen for fault isolation.
346 words, about 2 min02Elastic Compute Service (ECS)
An ECS instance is defined by instance type (vCPU/memory family: general, compute-optimized, memory-optimized, GPU), image (public, custom, shared, marketplace), system disk and data disks , network (VPC vSwitch, private IP, optional public IP/EIP), and security group . Instance families map to workload shape; picking the wrong family is a performance and cost error.
327 words, about 2 min03Networking: VPC, SLB, DNS, EIP
A VPC is an isolated private network with a CIDR block. Inside it, vSwitches carve subnets bound to a single zone.
353 words, about 2 min04Storage: OSS, NAS, Block Storage, Hybrid Backup
Block storage (cloud disks) - attached to one ECS instance, low latency, for OS and databases. Types: ESSD (high performance, PL levels), SSD , ultra disk , basic disk .
342 words, about 2 min05Databases: ApsaraDB for RDS, PolarDB, Redis, MongoDB
ApsaraDB for RDS is managed MySQL, SQL Server, PostgreSQL, or MariaDB: automated backup, patching, and HA via primary/standby. PolarDB is a cloud-native relational engine with compute-storage separation, read replicas sharing storage, and fast scaling - better for high concurrency and elastic read scaling.
335 words, about 2 min06Security and Identity: RAM, Security Center, WAF, Anti-DDoS
RAM (Resource Access Management) controls who can do what. Users, groups, and roles are granted policies (system or custom) that allow or deny actions on resources.
337 words, about 2 min07Auto Scaling and Elasticity
Auto Scaling manages a fleet of ECS instances via a scaling group (min/max/desired capacity), a scaling configuration or launch template (image, instance type, security group, SLB attachment), and scaling rules driven by triggers (scheduled or metric-based via CloudMonitor alarms). Instances are added or removed to hold desired capacity.
331 words, about 2 min08Monitoring, Operations, and Troubleshooting
CloudMonitor collects metrics (CPU, memory with agent, disk, network), sets alarms , and drives notifications and Auto Scaling. ActionTrail records API-level audit events.
345 words, about 2 min09Billing, Cost Management, and Resource Planning
Alibaba Cloud bills per resource on models: subscription (prepaid), pay-as-you-go (postpaid, metered), and spot . Costs are visible through bills , cost analysis , and budgets .
