Xinja Bank: AWS Journey

  1. 1. 1
  2. 2. XINJABANKLTD2019 2 Xinja Bank: AWS Journey Greg Steel - CIO AWS Taiwan October 2019
  3. 3. XINJABANKLTD2019 3 Xinja is an independent, 100% digital ‘neobank’. Designed for mobile. Made for people.
  4. 4. XINJABANKLTD2019 4 1. No dickheads… However good they may be. No dress code, but sometimes you need to look smart :-). No power trips because of a hierarchy. Intellect, customer experience and implementation is all that matters. 2. Everything is in the cloud. 3. We use real-time data to evaluate our business and we reward staff on a quarterly basis with an entirely discretionary profit share. No one gets a share of the profit if our investors aren’t making money and our customers aren’t happy. 4. We are here to make money, that’s why we exist, and we don’t screw people over to do it. We don’t lie to our clients in person or in marketing. We don’t engage in immoral lending; if our grandmother would think it was wrong, then it is. We aim to make lots of money ethically and we are proud of it. 5. No one is entitled to work at Xinja. It is a huge honour to represent people’s hopes of a new bank and we earn that honour every day. Xinja’s 10 Golden Rules
  5. 5. XINJABANKLTD2019 5 6. We look after our people bloody well. We stand by them if they are in genuine need. 7. We are truthful and direct with each other. Everyone says what they think in a robust, challenging, edgy environment. That means we won’t be the right place for everyone to work, and that’s ok. 8. We only hire people better than us. We never, ever settle because we need a body. We do psychometric testing to get the best people, every time. 9. About half our team, executive and board will be female, if they aren’t we aren’t recruiting the best people. We actively seek all types of diversity combined with brilliance. 10. If you discriminate against someone because of who they love/sleep with, you’re a dickhead… Please see rule 1. Xinja’s 10 Golden Rules
  6. 6. XINJABANKLTD2019 6 Xinja approach
  7. 7. XINJABANKLTD2019 7 Principle: Xinja is building a new bank to help customers do better Fact: Cloud is the answer for modernisation, security, agility & cost Xinja unleashes the power of our technology suppliers like AWS
  8. 8. XINJABANKLTD2019 8 Xinja Overview ● Composed from many world-class, modern, cloud- based services ● Xinja Services layer is an event-based microservices architecture that provides integration between all services, and is where we innovate ● Xinja Data layer is where we aggregate all data and deploy a range of data pipelines 8
  9. 9. XINJABANKLTD2019 9 Why Cloud? ● Cost! Try building a new Bank in a Datacentre! The people-costs alone would be devastating. Time factors would be unworkable. ● Skillsets. Traditional build requires Infrastructure Architects, Network Architects, Security Architects, engineers, contracts, many suppliers, etc. At Xinja this was all done by one architect, 2 devops staff, and help from key suppliers ● Agility. We did not know what the end-state would look like, we built our infrastructure, networks and security through trial and error (and loads of testing). You simply cannot do this with traditional infrastructure ● Automation. On the Cloud everything can be automated. Automation collateral is managed like source code, it captures design, configuration and knowledge. We automate everything!
  10. 10. XINJABANKLTD2019 10 Why AWS? At Xinja we prioritised Speed-to-market, Security and Quality. We chose to embrace AWS, taking full advantage of sophisticated services that provide: ● Great outcomes especially when services are used the way they are designed to be used - AWS Best Practices are Gold ● Strong Information Security Xinja has been able to satisfy the Australian Regulator’s latest Cyber Security standard CPS-234 We have also deployed a fully PCI-compliant solution using low-cost serverless infrastructure ● Agility, Scalability and Robustness Allowed us to meet unknown challenges
