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
