Steps And Precautions For Migrating Local Services To Taiwan Cloud Server Amazon

migrating local services to amazon aws taiwan cloud server can improve access speed, availability and elasticity. this article is intended for technical and operation and maintenance personnel. it explains the key steps of preparation, migration, testing and launch according to the actual migration process, and provides purchase suggestions and risk control.

preparatory work before migration includes asset inventory: confirm the applications, databases, static resources and domain names to be migrated. back up all data, export database snapshots, and record current server configuration (cpu, memory, disk, network bandwidth). at the same time, check the domain name whois information and dns access point, and appropriately reduce the ttl so that the switch can take effect quickly.

when choosing cloud services, it is recommended to give priority to instances (ec2) in the amazon aws taiwan region, and select the appropriate instance type and ebs storage based on the business load. if you need lightweight vps or hosting, you can also consider aws lightsail or a third-party vps provider. it is recommended to purchase elastic ip, vpc and subnet design to ensure network isolation and security.

network and acceleration strategies cannot be ignored: configure elastic load balancing (elb) to distribute traffic, bind elastic ips, and deploy cdn to accelerate static resources. you can choose aws cloudfront or domestic and foreign third-party cdn services to optimize access speeds in taiwan and surrounding areas. pay attention to caching policies, https certificates, and bandwidth billing when purchasing a cdn.

in terms of security protection, security groups, network acls, waf and ddos protection must be deployed. aws provides shield and waf services, but for high-risk businesses it is recommended to purchase high-defense ddos services (high-defense ip or hardware protection) to resist large traffic attacks. properly configure inbound/outbound rules and enable log auditing.

data migration steps usually include: 1) full backup and incremental synchronization; 2) transfer data using rsync, scp, aws s3 + cli or database replication (such as mysql master-slave, dms); 3) verify data integrity on the target server; 4) gradually switch traffic and monitor errors. keep the source read-only or use double-write during migration to avoid data loss.

it is recommended to use grayscale release for switching and verification: first verify the functions and performance on small traffic or test subdomains, and use monitoring tools (cloudwatch, prometheus, etc.) to observe cpu, memory, bandwidth, and response latency. make sure the ttl has been lowered when switching dns and prepare a rollback scenario to quickly restore to the original environment.

operations and maintenance after the migration is completed include automated backup, regular security scans, log centralization and alarm configuration. it is recommended to purchase commercial-grade backup and monitoring services, and combine them with configuration management tools (ansible, terraform) to implement infrastructure as code to reduce the risk of human error and optimize costs.

in terms of cost and compliance, evaluate bandwidth billing, storage classes, and instance idle time, and use a combination of on-demand and reserved instances to optimize costs. long-term planning is also required for domain name management and certificate renewal. if necessary, purchase managed domain name and certificate services to simplify maintenance.

if you need migration consultation, purchase of taiwan aws instances, cdn or high-defense ddos solutions, we recommend contacting dexun telecommunications. dexun telecom provides professional cloud server and vps procurement, domain name registration, cdn access and high-defense ddos deployment services, and can assist with full migration and operation and maintenance optimization to help you quickly and safely migrate local services to the taiwan cloud.
