1 ATO System Improvements Industry Engagement Forum Presented by Ian Scensor Australian Taxation Office 29 August

2 Improvements implemented to date Improvements Infrastructure Investment Performance and operational improvements Migrated to the new SAN architecture with full data replication Moved two key applications to cloud operations (ato.gov.au and ATO Online) Enhancementsto the operations monitoring centre to bolsterproactive monitoring capability of our systems Centralised log monitoring processes to manage the myriad of system logs to improve operational performance Process, tools and governance Refined playbooks to enhance speed of recovery Codified manual activities Improvements to the IT incident management process and interface with ATO Business Continuity Management Architect for resilience Established many of the single point of failure systems in the second data centre UNCLASSIFIED SuperStream Business Engagement Forum 2

3 Improving SBR2 Re-architecture Performance and operational improvements Phase 1 Initial focus (current architecture) Improving performance and availability From Dec 2016 Implementing performance improvements to enhance throughput and response times of SBR2 transactions Addressing single points of failure in the SBR2 channel Infrastructure investment Phase 2 Now Migration to cloud From August 2017 Staged ramp up of Digital Service Providers (DSPs) on AWS cloud Phase 3 Future Re-architecting for improved resilience 2017 and beyond Establishing service patterns Decoupling SBR2 from the broader ATO technology environment UNCLASSIFIED SuperStream Business Engagement Forum 3

5 Infrastructure Investment Migration to cloud SBR2 Connections (On-premise and AWS cloud) Connection during staged implementation Access to AWS ecommerce Cloud or ecommerce on-prem is activated by a change in the DSP application to send to one of the two URLS. The DSP application can point to either URL provided their product remains whitelisted in both AWS and on-prem solutions. DSP DSP URL URL AWS On-prem What information is expected from Super early adopters? 1. Service to be utilised (e.g. SMAT2) 2. Agreed trustee participation 3. Timeframes for implementation CLASSIFICATION SuperStream Business Engagement Forum 5

8 Re-architecting Decoupling back-end systems to improve resilience Note: This slide represents early thinking. The future architecture patterns are still being explored. Queued Batch Submit batch and bulk transactions which will be validated, queued and a submission receipt is returned. Limited Service Mode Single interactive transactions will be validated and stored until back-end systems are available. A submission receipt is returned. Users are able to complete obligations but need to return for response when systems are available. Access Response Access processed responses on the channel even if back-end systems are unavailable. Access Key Reports Access key reports and informational services available on the channel. Access Offline Data Access key personal and identification information and pre-fill data from a secondary data source. Users are advised of the currency of data as limitation on service.
