Its mobile payment solution, PayLah, is cloud-hosted. Its mobile-only Digibank app, first launched in India, is also in the cloud.\n\u201cWe were previously constrained by our ability to scale, but the cloud has presented us with an opportunity to experiment like we couldn\u2019t do in the past,\u201d explains David Gledhill, CIO at DBS Bank Group.\nDigibank, which features three fintech products \u2013 the chatbot called Kasisto; a personalised spending recommendation product, Moneythor; and an in-app security locker, V-Key\u00a0\u2013 has also been launched in Indonesia.\nBut even from within, some of DBS\u2019s internal operations are also run on the cloud. The bank uses Amazon Web Services\u2019 (AWS) compute-as-a-service offering, Microsoft\u2019s Office 365 productivity suite, and Akamai\u2019s cloud-based web application accelerator and DDoS protection.\n\u201cIt\u2019s inevitable when people use the cloud as part of their workflows,\u201d Gledhill explains. \u201cAWS and other cloud providers are just going to get better at implementing and managing security overtime due to the scale at which they operate. They can get things done much more consistently than we can ever hope to do within our own company.\u201d\nIt\u2019s true that the core banking platforms can\u2019t be all be moved to the cloud because of architecture issues, but Gledhill says the priority is \u201cto work on making those applications cloud ready.\u201d \nThe bank has identified applications that can be prioritised for cloud migration, and Gledhill says they fall on two categories: mobile applications and applications that deal with data and analytics. \n\u201cWe\u2019re seeing a greater demand for big data\/analytics versus any urgency to get mobile apps onto the cloud,\u201d he says, adding that the challenge for DBS Bank is how to apply traditional layers of controls for cloud-run applications.\nThere is also the issue of whether to stick with a single provider or go the multiple provider route.\n\u201cOne layer of going onto the cloud involves utilizing just cloud servers and storage from a provider like AWS, but doing that alone doesn\u2019t get you far until you\u2019ve embraced other associated applications such as Lambda, Redshift, and Aurora. Right now, the bigger question would probably concern which software products look the most attractive to us, and how deeply we\u2019ll wish to invest in a single provider,\u201d he said.\nEven with various issues and challenges, the DBS bank executive says that the cloud is the way to go for them.\n\u201cWe\u2019ll never catch up if we stick to building our own data centres, we\u2019ll always be some two years behind,\u201d states Gledhill.\nPart of the reason is for fast implementation of innovations. \u201cWe need to run like a 22,000 person startup. You can\u2019t move very far as a bank today if you can\u2019t achieve that,\u201d he concluded.
