Driving Innovation with Legacy Systems in FSI

Richard Pain | May 17, 2017
Complex legacy IT systems can inhibit digital transformation. To learn how to tackle this challenge, we speak with innovation expert Thunaiselvam Ramasamy, Chief Architect at Juniper Networks.


"When it comes to modernising these applications, it can lead to downtime which would be unacceptable for customers and stakeholders. Also finding developers who can work with archaic programming languages can be difficult too. To get around this, FSI organisations need to look at how they can develop a platform and test the integration process of these legacy applications, to get them working with the increasing number of cloud native applications which are being used in the industry."

This idea of having a platform to develop and test modernised legacy applications is especially important due to the security implications. Connecting legacy systems with the cloud and mobile devices widens the IT perimeter and increases their vulnerability to disruption or data loss, two critical concerns due to industry regulations, which contributes additional complexity to the modernisation of any legacy systems.

"One large bank in the US came to us with a problem," explains Ramasamy, "saying that any change in their applications typically took about six and a half month to develop and launch. So we initiated the integration of an open API with a range of their legacy applications using Juniper OpenLab, as well as some other open source tools. This took approximately three months to test and integrate everything, but at the end of the process, the bank now had the capability to roll out application changes or even launch entirely new applications in 14 days flat. That's a major competitive advantage in terms of reduced cost, reduced risk and of course, greatly reduced time to market.

"Having this underlying platform, facilitated by Juniper OpenLab, provides customers with complete openness, flexibility and agility, allowing them to integrate their applications with the backend. That's the biggest benefit we hear back from customers once we have completed a digital or automation journey with them."


Discover Juniper OpenLab

OpenLab is a centre of innovation provided by Juniper, for business leaders who want to build network-integrated software applications and solutions quickly and securely. This is done by offering hands-on and cloud-based access to Juniper and third-party solutions including SDN sandboxes and NFV interoperability testing.

Each of the seven OpenLabs around the world, including one in Singapore, is comprised of three primary assets: a globally-accessible lab, a facility to support various engagements with 3rd parties and an education centre.

On the education side, each OpenLab hosts technology training sessions to explore the possibilities enabled by Juniper's programmable virtual and physical platforms. These include Throwdowns, special SDN/network automation workshops and competitions, to help participants bolster their skills and prepare them to take advantage of emerging technologies.

If your organisation is struggling to drive innovation due to its legacy applications, you can learn more about how OpenLab can help you here.
