Alibaba Cloud

Core Capabilities

Provides expert guidance across Alibaba Cloud ecosystem:

1. Compute Services - ECS instances, Auto Scaling, Container Service (ACK), Function Compute
2. Storage & Database - OSS object storage, ApsaraDB (RDS, Redis, MongoDB), NAS, Block Storage
3. Networking - VPC, SLB (Server Load Balancer), VPN Gateway, CEN, NAT Gateway
4. Security & Identity - RAM (Resource Access Management), Security Center, WAF, Anti-DDoS
5. Application Services - API Gateway, Message Service (MNS/MQ), DirectMail, SMS
6. DevOps & Monitoring - CloudMonitor, Log Service, ARMS, Container Registry
7. CDN & Edge - Alibaba Cloud CDN, DCDN, Global Accelerator
8. Data & Analytics - DataWorks, MaxCompute, AnalyticDB, E-MapReduce

Best Practices

Architecture

• Deploy across multiple zones for high availability
• Use SLB for load balancing with health checks
• Implement Auto Scaling for dynamic capacity
• Configure CloudMonitor with actionable alerts

Security

• Enable RAM with least privilege access control
• Use Security Groups and Network ACLs for filtering
• Enable encryption at rest and in transit
• Implement WAF and Anti-DDoS for protection
• Enable ActionTrail for audit logging

Cost Optimization

• Use Reserved Instances for predictable workloads (up to 70% savings)
• Leverage Preemptible Instances for batch jobs
• Configure Auto Scaling to match demand
• Use OSS lifecycle policies for cold data
• Monitor with Cost Management dashboards

Performance

• Choose appropriate instance families and sizes
• Implement Redis/Memcache for caching
• Use CDN for static content delivery
• Configure read replicas for databases
• Enable ESSD disks for high IOPS workloads

Infrastructure as Code

Terraform for Alibaba Cloud

terraform {
  required_providers {
    alicloud = {
      source  = "aliyun/alicloud"
      version = "~> 1.200"
    }
  }
}

provider "alicloud" {
  region = "cn-hangzhou"
}

# VPC with multi-zone deployment
resource "alicloud_vpc" "main" {
  vpc_name   = "production-vpc"
  cidr_block = "10.0.0.0/16"
}

resource "alicloud_vswitch" "app" {
  vpc_id     = alicloud_vpc.main.id
  cidr_block = "10.0.1.0/24"
  zone_id    = "cn-hangzhou-h"
}

resource "alicloud_security_group" "app" {
  vpc_id = alicloud_vpc.main.id
  name   = "application-sg"
}

resource "alicloud_instance" "app" {
  instance_name              = "app-server"
  instance_type              = "ecs.g6.large"
  image_id                   = "ubuntu_20_04_x64"
  vswitch_id                 = alicloud_vswitch.app.id
  security_groups            = [alicloud_security_group.app.id]
  internet_max_bandwidth_out = 10
}

China-Specific Considerations

ICP Filing

• Required for websites hosted in mainland China
• Obtain before pointing domain to Alibaba Cloud
• Allow 20-30 business days for approval
• Different requirements for personal vs corporate

Data Residency & Compliance

• Data localization laws require China region storage
• Use: cn-hangzhou, cn-shanghai, cn-beijing, cn-shenzhen
• Understand Cybersecurity Law and Data Security Law
• Cross-border transfer requires security assessment

Network & Performance

• Great Wall Firewall impacts international connectivity
• Use China CDN for domestic users
• Use Global Accelerator for cross-border access
• Test from within China for accurate results

Migration to Alibaba Cloud

Assessment

1. Inventory infrastructure, applications, and dependencies
2. Analyze regulatory requirements (ICP, data residency)
3. Map services to Alibaba Cloud equivalents
4. Estimate costs with pricing calculator
5. Plan connectivity (VPN Gateway, Express Connect)

Strategies

• Rehost - Lift and shift with minimal changes
• Replatform - Optimize with managed services (RDS, OSS, Redis)
• Refactor - Rebuild with cloud-native services (Function Compute, ACK)
• Hybrid - Partial migration with on-premises connectivity

Execution

1. Set up account and configure RAM
2. Establish network connectivity
3. Create VPC, VSwitches, security groups
4. Migrate data to OSS/RDS
5. Deploy applications to ECS/ACK
6. Configure SLB and DNS
7. Set up CloudMonitor and Log Service
8. Test and execute cutover
