Using Tyk to increase Transactions per second by more than 100%


SK techx is a leading South Korean company specialising in mobile platform technology and applications.

Though SK techx deals with a number of APIs as part of its day-to-day business, the weather API is central to the company’s B2B and B2C applications, including Weather Pong, and a number of external applications paying to use the service.


Though the original SK techx API Gateway was developed and used in-house, the team were finding they lacked the time to continually improve and refine the solution. When it became time to create a new one entirely, the team began to consider a third-party solution.

SK techx set to work comparing several API Gateway and Management solutions – both proprietary and open source, and building a proof of concept with each.


Tyk stood out of the thorough evaluation for three big reasons: its stability, strong performance in benchmark tests, and ability to be seamlessly integrated with a token-based authentication system, appkey, out of the box.

The icing on the cake was Tyk’s open source code base; a key consideration for the SK techx team was using an open source provider so that they could modify the source directly, which they required for customisation.

Day-to-day, the team’s use of Tyk focuses on the API Gateway and authentication, rate settling, quota limits and analytics features.

SK techx also benefitted from clear and improved operation and installation guides, Tyk documentation, and responsive help and support from the Tyk team.


After switching to Tyk for their API Management needs, SK techx saw huge performance improvements, and found Tyk better at handling their API traffic compared to the previous, internal solution.

The API now handles almost 35 million Transactions per Day (TPD), and at peak times can handle 20,000 Transactions per Second (TPS); double the team’s previous target.

Tyk’s ability to be endlessly customised, and integrated with other systems, also allows SK techx the ability to easily add their own additional services to the Gateway. This saves them much-needed time and resources, as well as increasing Gateway and Platform flexibility.

Plans for the future of SK techx’s APIs include further customisations and integrations, and implementation of the Tyk Developer Portal to share the weather API with developers globally.
