Proof of performance: Stability and data synchronisation over the cloud with Colt Dedicated Cloud Access

TIS Inc.

TIS IT Holdings Group furnishes various IT-as-a-service solutions, including cloud and data centre, as well as system integration and OEM. At the same time, the company maintains global support capabilities based in the China and ASEAN regions. It is partnered with and contributes to the growth of over 3,000 organisations in finance, manufacturing, trade, service, government, etc.

TIS’s business challenge

Along with the burgeoning global expansion of public cloud, TIS’s own customer base was increasingly seeking ways to connect on-premise IT to wider infrastructure. At the same time, TIS needed to conduct disaster recovery tests between their data centre and high-speed private network in conjunction with SoftLayer. Colt was selected to provide SoftLayer DirectLink connectivity for the tests, which would also serve as a trial run for future TIS-Colt collaboration.

Why Colt

Connecting end-customer environments to the cloud required high quality and stability, both of which Colt Dedicated Cloud Access services are known for. Furthermore, with Colt Dedicated Cloud Access, there was no need to sign a contract for racks at Equinix, allowing TIS to keep startup costs down.

TIS was able to verify the quality of connectivity using Colt Dedicated Cloud Access. The verification test was conducted by connecting the TIS data centre to Bluemix Infrastructure via Colt Dedicated Cloud Access and by implementing distributed storage at Bluemix Infrastructure data centres in San Jose, Tokyo, and TIS’s Tokyo DC. The result provided stable throughput with average RTT of less than 1 ms between Bluemix Infrastracture Tokyo and TIS Tokyo data centres.

Furthermore, Colt was able provide further support by bridging communications between TIS and Bluemix Infrastructure’s English-speaking engineers and ticketing system.

Future plans

Getting the most out of the cloud requires robust connectivity to that cloud in terms of quality and redundancy. Colt Dedicated Cloud Access proved itself in both regards as verified by the TIS tests. TIS is now considering ways to further utilise Colt services for DR and other purposes.

By using Colt Dedicated Cloud Access, we saw actual throughput for cloudbased data syncing achieve extremely good stability, boding well for disaster-preparedness. We believe that Colt’s high-quality etherXEN circuits will play a crucial role in connecting our data centres to the cloud and propelling our hybrid cloud operationsYasutsugu Ishibashi, Senior Expert, Strategic Technology Center, TIS Inc.
