Always-on● Designed to handle any failure,

no matter how catastrophic.

● Take advantage of every opportunity.

● Focus on what matters most to you.

Instant insight● Built into your application to

create actionable, modern experiences.

Quick Overview of PSD2

• PSD2 EU Regulations are designed to allow all Payment Initiation Service Providers (PISPs) and Account Information Service Providers (AISPs) to connect to Account Servicing Payment Service Providers (AS PSP) in a secure and effective manner.

• PSD2 does not specify the APIs• UK Open Banking Working Group provides an API standard for

banks and third parties to integrate.• API Access Requirements for AISP

– Authentication / Authorization, Customer, Account, Transaction information

• API Requirements for PISP– Authentication / Authorization, Customer, Account information,

Transaction Authorization

TPPsThird PartyProviders

Payments and Transactions References

• Transaction history tagging, search and budgeting, cash flow prediction

• Product recommendation based on purchasing history.• Data safe against loss of node, rack, or data center.• Shed load from legacy systems to reduce cost and provide better

user experience.

“We had reached the limits of our scalability. We wanted to remove all single points of failure. We had to be active-active. That's why we chose Cassandra.”

Linear Scale

Fault Tolerant

– Nodes Down != Database Down– Datacenter Down != Database Down– Upgrade != Database Down

Benefits of DataStax Enterprise for PSD2 / OB APIs

• Provides an always-on and scalable database for APIs layer– Fully active geo-distribution– Linear scalability

• Reduce the performance impact and MIPS costs on the legacy systems

– Only reach the mainframe for transactions after having checked the balance in Datastax Enterprise

• Low response time and scalability make possible to have a stateless API layer

– Allows easiness of deployment and scalability of the API layer

Demo

• Sample transaction history from the open bank group

• Provide an implementation for the ‘transactions’ API call

• Provide additional services like auditing and event logging

• Buying time for a digital transformation of legacy systems
