The Technical Architect Recommends Things To Pay Attention To When Choosing Hengchuang Technology For Japanese Cloud Servers.

1.

preliminary preparation and goal confirmation

steps and sub-sections: 1) clarify business goals: latency threshold, bandwidth requirements, compliance requirements (such as appi) and disaster recovery rto/rpo; 2) list existing assets: application architecture, database, certificate, ip whitelist; 3) develop an evaluation table: performance, cost, support response time, interface (api/cli), billing model; 4) prepare test account and sample traffic (production portrayal).

2.

account registration and permission configuration

steps and sub-sections: 1) register a corporate account on the official website of hengchuang technology and complete real-name authentication; 2) create a sub-account and role (iam), granting only minimum permissions; 3) configure an ssh key/key pair for subsequent instance logins; 4) enable bill alarms and cost centers on the console to track expenses.

3.

region and computer room selection (tokyo/osaka/others)

steps and sub-sections: 1) select the nearest available zone based on user distribution; 2) ask hengchuang to provide the physical computer room topology, backbone interconnection and peering operator list; 3) if more availability is required, select at least two different computer rooms/available zones; 4) evaluate whether the bandwidth entrance and public network ip pool meet the needs.

4.

network quality and delay testing practice

steps and subsections: 1) execute ping <target ip> and traceroute/tracert <target ip> (linux: traceroute, windows: tracert) from your source site; 2) use mtr <target ip> to observe packet loss and hop delay; 3) use iperf3 -c <target ip> -p <port> to measure throughput (the peer needs to enable the iperf3 service); 4) compare the results of different availability zones and different time periods (peak/off-peak) and record them.

5.

bandwidth, peak and billing verification

steps and subsections: 1) apply for a short-term pay-as-you-go trial or test password and simulate peak traffic to see billing performance; 2) query the bandwidth limit and additional billing rules through the console or api; 3) conduct bandwidth burst scenario testing (concurrent connections, short-term throughput peaks); 4) confirm overage protection and alarm threshold settings with sales or technical support.

6.

security and compliance template configuration

steps and subsections: 1) configure security group/firewall rules: deny all incoming traffic by default and open ports on demand; 2) enable host hardening: turn off useless services, limit ssh login source ip and use key authentication; 3) log concentration: configure syslog or elk, prometheus collection; 4) require hengchuang to provide compliance certificates (such as iso/iec or local compliance files).

7.

storage, backup and snapshot strategies

steps and subsections: 1) design i/o tiering: separate system disk/data disk, select block storage or local disk according to iops; 2) write automatic snapshot strategy: such as daily full volume, hourly increment and retention period; 3) test recovery process: restore from snapshot to new instance and verify data consistency; 4) configure cross-region off-site backup to meet rpo requirements.

8.

high availability and disaster recovery drills

steps and sub-sections: 1) design multi-availability zone load balancing (using hengchuang's lb or self-built haproxy/nginx); 2) build a health check and automatic elimination of failed instances strategy; 3) write disaster recovery scripts: dns switching, database master-slave promotion scripts and conduct regular drills; 4) record drill results and correct sops.

9.

deployment process (from console to automation)

steps and subsections: 1) manual deployment on the console: select the image, configuration specifications, network and security group; 2) automated deployment: use the api or terraform module provided by hengchuang, write the tf file and execute terraform plan/apply; 3) add environment variables and key management to ci/cd (do not hardcode); 4) execute health verification scripts (curl /health, db connect, etc.) after deployment.

10.

application migration and data synchronization practice

steps and small segments: 1) small-scale grayscale migration: migrate non-core traffic or development environment first; 2) database migration: use logical replication/physical replication or tools (mysqldump + binlog, pg_basebackup); 3) verify consistency: checksum or compare sample data; 4) switch production traffic and monitor error rate and latency.

11.

monitoring, alarming and sre manual preparation

steps and sub-sections: 1) set key indicators (cpu, memory, disk, latency, error rate, qps); 2) configure alarm strategy: multi-level alarm and notification channels (sms/dingtalk/e-mail); 3) write emergency sop (fault location commands, log paths, rollback steps); 4) conduct regular drills and update the manual.

12.

key points for cost optimization and contract negotiation

steps and subsections: 1) compare the costs of pay-per-volume, annual/monthly subscription and reserved instances; 2) require transparent traffic billing and peak-valley pricing examples; 3) negotiate support terms: free technical support duration, response sla and upgrade channels; 4) record refund, data retrieval and service termination terms in the contract.

13.

acceptance and long-term operation and maintenance matrix

steps and sub-sections: 1) prepare an acceptance list: performance, availability, security, backup and recovery, documentation; 2) verify through stress testing and fault injection; 3) hold regular docking meetings with hengchuang technology to evaluate network interconnection and routing changes; 4) establish long-term kpis (sla achievement rate, average recovery time, number of failures).

14.

frequently asked questions - q: how to quickly verify whether hengchuang's delay in japan meets the requirements?

answer: operation steps: 1) obtain the public ip or test domain name of hengchuang's japanese computer room; 2) execute ping and mtr on your representative node; 3) use iperf3 for throughput testing (if the other party provides iperf service); 4) repeat the test at different time periods and count the 95th percentile delay and packet loss rate. if the target is exceeded, work with hengchuang technical support to locate routing or link problems.

15.

frequently asked questions—q: if i need a cross-border dedicated line or low-latency interconnection, how should i connect with hengchuang?

answer: operation steps: 1) ask hengchuang for the available direct connection/dedicated line product description and third-party carrier list; 2) provide your local data center or cloud docking point information and confirm the bgp asn and ip segment; 3) work with hengchuang and the carrier to develop a test plan (including loop test and throughput test); 4) conduct end-to-end performance and failover drills after the dedicated line is opened.

16.

frequently asked questions - q: how to obtain support efficiently when encountering problems during actual deployment?

answer: operation steps: 1) attach the recurrence steps, log, mtr/traceroute results and timestamp to the work order; 2) specify the emergency level and follow up within the sla time; 3) require a remote session (ssh/remote desktop) so that engineers can directly troubleshoot; 4) record the processing process and final solution, and update the team sop to reduce future recurrence rates.
