How To Do Domain Name Resolution And Cdn Configuration Suggestions For Singapore Cloud Server Websites

when building a website on a singapore cloud server , reasonable domain name resolution and cdn configuration can significantly improve access speed and stability. this is especially important for websites targeting users in southeast asia, australia, or southern china.

the first step is to choose a suitable server or vps: it is recommended to estimate the cpu, memory and bandwidth based on the number of visits and concurrency. if there is a risk of attack, choose a host with high anti-ddos capabilities or purchase a high-defense package on demand. newbies can choose 1-core 2g to start. for production environments, 2-core 4g and above are recommended, and snapshots and backup plans should be reserved.

in terms of domain name registration and resolution, after purchasing the domain name, set the a record (pointing to ipv4) and/or aaaa record (pointing to ipv6) in the domain name management console, add resolution to both the root domain name and the www subdomain, and if necessary, configure the cname to point to the domain name provided by the cdn to achieve static resource acceleration.

if you use self-built dns or want higher resolution stability, it is recommended to use an authoritative dns service or the secondary resolution provided by cdn vendors, enable reasonable dns ttl settings (for example, 60-300 seconds during the debugging period, and the production environment can be appropriately increased), and enable dnssec to prevent hijacking.

key points for cdn configuration: choose a cdn that supports custom certificates, enable https back-to-origin and front-end https, and enable http/2 or http/3 to improve concurrency performance. connect the accelerated domain name to the cdn through cname, set the back-to-origin type to http or https, and bind the origin ip or origin domain name.

the caching strategy should be refined: set long cache (max-age of more than 7 days) for static resources such as images, js, and css, use edge caching for homepage or dynamic pages and combine cache keys with cache rules. if necessary, configure cache exceptions and instant refresh functions so that content updates can take effect immediately.

in terms of security configuration, enable waf (web application firewall) rules, sql injection and xss protection, as well as rate limiting and ip black and white lists. for ddos anti-ddos advanced, it is recommended to choose a service with a cleaning threshold or a cleaning solution based on traffic billing, and configure an emergency switching strategy.

certificate management cannot be ignored: you can use let's encrypt free certificates or purchase commercial certificates to ensure that the certificates are deployed and automatically renewed on both the cdn and the origin site. enable hsts and force https redirection to ensure transmission security.

email and subsystem configuration: if the website needs to send emails, be sure to configure spf, dkim and dmarc records; if you use a custom email server, set up correct mx and ptr reverse resolution to avoid being judged as spam.

monitoring and logging: deploy access monitoring, bandwidth and traffic alarms, waf and ddos event logs, combine cdn and origin site logs to analyze access hotspots and attack sources, and regularly review and optimize rules and cache hit rates.

operation, maintenance and backup recommendations: use automated deployment scripts, ci/cd pipelines and scheduled backups, and establish emergency plans (such as switching to backup nodes, enabling read-only pages or directing traffic to backup sites) to deal with sudden failures or attacks.

purchasing suggestion: if you want to solve your parsing, cdn and high-defense needs in one stop, you can choose a cloud service provider or hosting service provider with integration capabilities to purchase a package. compare the peak bandwidth, cleaning capabilities, sla and technical support response speed. you can apply for a trial before purchasing to verify the effect.

summary of the implementation process: 1) purchase a server/host and configure a security group; 2) register and add a/aaaa/cname and other records in the domain name management office; 3) connect to cdn and configure return-to-origin, certificate and cache rules; 4) enable waf and high-defense strategies; 5) monitor, back up and optimize regularly.
