Government Linked Investment Company

AWS Case Study

A Singapore government related investment company managing over US$100billion in assets in over 40 countries worldwide.


The company started to adopt public cloud on AWS back from early 2016 and they had been migrating their existing / legacy systems to AWS and also setting up new projects and applications over in AWS. However, they had experienced network connectivity performance and stability issues, and have also had concerns over security using the Public Internet to communicate between their physical data centres and systems on AWS. They were looking for a high performance, highly resilient, secure and scalable natively-private communication solution to connect to their AWS infrastructure from their physical locations.


Based on company’s technical requirement and expectations, back in 2016, 1cloudstar had proposed and implemented an end-to-end managed AWS Direct Connect solution to connect to company’s two data centres using redundant private point-to-point circuits from different local ISPs, and using managed CE (custom edge) routers to dynamically route the AWS cloud-bound traffic with flow-based traffic load-balancing and automatic failover feature via well planned and implemented BGP (Board Gateway Protocol) routing framework. In addition, 1cloudstar also enabled IPSEC encryption over the private WAN links to further enhance the network security. Lastly, 1cloudstar connected company to both AWS Private Peering (for AWS VM/VPC communication) and AWS Public Peering (for AWS Public Services communication) from company’s physical locations.

From its initial setup, the infrastructure had been kept on enhanced and expanded with more and more AWS VPCs and services connected, and much higher private link bandwidth (initially 1 x 30mbps link, currently 2 x 1Gbps, and now we are planning and proposing to further upgrade it to 2 x 2Gbps link) to meet the continuous cloud infrastructure expansion. This effective and scalable connectivity solution supported and empowered the rapid implementation and expansion of company’s cloud initiatives over the past few years, and enabled them to move a lot of key, mission-critical production applications and systems completely into AWS.
