Hybrid Cloud And Vpc Interconnection Deployment Examples Provided By Singapore Cloud Server Cn2 Service Provider

1.

overview: why choose singapore cn2 hybrid cloud and vpc interworking

reasons for supporting mainland china’s high-quality link cn2: reducing cross-border delays, improving stability, and suitable for connecting chinese users.
the value points of hybrid cloud: localized computing + cloud elasticity, which facilitates data sovereignty and disaster recovery.
the purpose of vpc interoperability is to realize private network interconnection and direct connection to databases and applications to avoid public network exposure.
applicable scenarios: e-commerce, high-concurrency api, real-time audio and video, cross-border saas.
dependent components: cloud host, dedicated line or vpn, routing strategy, load balancing and security equipment.

network architecture and deployment steps

step 1: evaluate the bandwidth and peak concurrency to determine the cn2 link bandwidth (200mbps in the example).
step 2: create a vpc on the singapore cloud side, divide the subnet into public/private, and deploy a nat gateway.
step 3: set up vpc peering or dedicated line interconnection (ipsec/sd-wan or mpls) and configure routing tables.
step 4: configure bgp and cn2 preferred paths, and test multiple link failover.
step 5: configure security groups, acls and log auditing to ensure that the database and management port are only reachable on the private network.

server and instance configuration examples (including tabular data)

example environment: e-commerce backend, peak concurrency of 10k, daily traffic of 1.2tb, rto target of 15 minutes.
example of instance specifications: the application layer uses 2x4 core 16gb, and the database uses 1x8 core 64gb high io instance.
storage and backup: the main library uses ssd 500gb, and off-site backup takes daily snapshots; object storage is used for static resources.
connection and speed limit: cn2 link 200mbps, redundant link 100mbps, set qos priority.
the following table shows typical instance configurations and network bandwidth:

role	example	cpu/memory	storage	outbound bandwidth
application server	2 units	4 cores/16gb	100gb ssd	100mbps
database master	1 unit	8 cores/64gb	500gb ssd	200mbps
backup/cache	1 unit	4 cores/32gb	1tb hdd	50mbps

cdn, ddos defense and domain name/ssl practice

cdn access: transfer static resources to near-origin cdn nodes to reduce bandwidth pressure on the origin site and improve global access speeds.
ddos protection: enable cleaning and protection strategies on the cloud side. threshold example: traffic burst suppression above 1gbps requires cleaning.
domain name strategy: use smart dns to point chinese users to the cn2 preferred line, and overseas users to the nearest acceleration node.
certificate and encryption: enable full-site https, use let's encrypt or paid certificate, tls1.2/1.3 is preferred.
monitoring alarms: configure bandwidth, connection number, error rate threshold alarms, and integrate prometheus/grafana or cloud monitoring.

real case: cross-border saas company implementation examples and effect data

background: a domestic saas uses singapore as its asia-pacific node, with users covering china and southeast asia.
deployment: deploy cn2 link 200mbps in singapore, vpc interconnection to domestic computer room, through ipsec redundancy.
configuration: application 2x4 core 16gb, database 1x8 core 64gb, cdn distributed globally, waf+ddos cleaning enabled at the same time.
effect data: after testing, the average rtt of the cn2 link for china's first-tier cities dropped from 60ms to 38ms, and the 99th delay dropped from 420ms to 220ms.
operational results: the average monthly availability reaches 99.99%, the peak traffic supports 12k concurrency, and there is no database master-slave switching event caused by network jitter.
