Cloud and Identity Architecture for Open Banking

Cloud-based Open Banking

In the feature video executives from Starling Bank talk through their AWS implementation achieving an entirely Cloud-based digital bank.

Built exclusively on AWS, Starling Bank’s 100% cloud-based, mobile-only banking solution satisfies regulators in terms of its resilience, security, and reliability. It also satisfies consumers by giving them greater control over their data, streamlining the account opening process, accelerating payments, and providing access to innovative new services developed from scratch with open APIs, a developer platform, integration with Apple Pay, Google Pay, and Fitbit Pay and a custom backend ledger and payments integrations.

Ronan Guilfoyle of AWS shares this presentation on implementing Open Banking APIs on the AWS Cloud.

Key highlights include:

Digital Identity Architecture

Digital Identity is such a strategically important foundation for Open Banking that players like Mastercard have taken the direct step of launching an Identity initiative with Microsoft.


Key standards groups include the OIX, who provide the framework for facilitating identity federations across a number of industries such as Government, underpinning the UK Government’s Verify service.

It is also pioneering how it might be used for enabling Open Banking, such as cross-border account opening, featuring the involvement of HSBC and Barclays.

In their white paper ‘Self Certification and Mandatory Assessment Regimes‘ they explore a comparison between the Verify scheme and how it might be applied in banking.


Leading vendors in this space include ForgeRock, selected in 2017 by the Open Banking Implementation Entity to develop a Reference Application.

ForgeRock are one of the Identity vendors referenced in the AWS Cloud implementation of Open Banking as a provider of the core Identity functionality, and in their presentation Implementing Open Banking with ForgeRock they expand upon this functionality in detail.

They were writing about the super heated segment of the tech sector that forms a keystone component part of Open Banking: Identity authentication.

TechCrunch writes the deal will enable a merged synergy between the two complimentary areas of focus for each:

While Plaid helps link your checking and savings account to modern financial apps like Venmo, Acorns and Robinhood, Quovo’s APIs are aimed at the investment side of the financial services market with up and coming customers like Betterment, Wealthfront and SoFi, and established players like Stifel, Vanguard, Empower Retirement and John Hancock.

Payment Source writes about the critical foundation role of Digital Identity plays in facilitating Open Banking services, highlighting how more than 120 countries have digital passports and more than 60 countries have national ID cards, and that ultimately synthesis of them all into a single global Identity framework is a shared goal for many sectors such as government as well as banking. Major initiatives include ID2020:

And the ID2020 initiative aims to use digital ID to boost financial inclusion, noting World Bank figures that show more than 1 billion people do not have a reliable ID. The ID2020 initiative, whose supporters include Accenture, Microsoft and the Hyperledger project, plans to use blockchain and the wide availability of smartphones to build sharable identity.
