ATO System Improvements

Improvements implemented to date

Improvements

Infrastructure

Investment

• Migrated to the new SAN architecture with full data replication

• Moved two key applications to cloud operations (ato.gov.au and ATO Online)

Performance and

operational

improvements

• Enhancements to the operations monitoring centre to bolster proactive

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

Improving SBR2


Phase 1 – Initial focus (current architecture)

Improving performance and availability

From Dec 2016

Phase 2 – Now

Migration to cloud

From August 2017

Infrastructure

Performance and

operational improvements

Re-architecture

• Implementing performance improvements to enhance

throughput and response times of SBR2 transactions

• Addressing single points of failure in the SBR2 channel

• Staged ramp up of Digital

Service Providers (DSPs) on AWS

cloud

• Establishing service patterns

• Decoupling SBR2 from the broader ATO

technology environment

Phase 3 – Future

Re-architecting for improved resilience

2017 and beyond

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.

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.

Note: This slide represents early thinking. The future architecture patterns are still being explored.
