A L A R G E A U S T R A L I A N I N V E S T M E N T B A N K

Delivery of a multi-cloud solution, mitigating the risk of having a single public cloud provider.

- Successful migration of critical and transactional banking microservices

- Increased resilience with embedded controls architecture

- Empowered developers with controls that live outside of deployment and a consumption mode that supports tooling choices

- Cloud native services deployed including Anthos Config Connector, Anthos Policy Controller,Deployment Manager and Google Kubernetes Engine

A T O P F I V E C A N A D I A N B A N K

Deployment of first material public-facing workload to Google Cloud.

- Timely delivery of mission-critical workload facing on-premise end-of-life event

- Upgraded architecture deploys across multiple regions to increase availability and durability whilst increasing performance

- Enabled first public ingress pattern for GCP, accelerating future public-facing applications

- Full CI/CD and Blue/Green deployment methodologies. Release and Rollback events are achieved inside a day

6 | Sourced Confidential

Sourced has worked with a broad set of highly regulated enterprises in varying stages of their cloud journey over the past decade.

Our consultants have consolidated this experience into a proven methodology, focusing on building a robust and scalable foundational capability that centralises compliance while allowing application teams to self-service their cloud infrastructure.

MaturityProvide a secure, consistent, and controlled deployment methodology allowing teams to gain significant maturity in public cloud within the enterprise’s approved guardrails

ScaleProvide a method to scale cloud deployments from one team to any number of teams without a linear increase in operational cost

OperationsMinimise operational irregularities and manual work through a consistent and automated approach to cloud

VelocityProvide consistency in outcomes through automation, reducing the number of unique assessments, reviews, and internal debate required to deliver value add

The Benefits

SecurityEnsure the enterprise’s security posture is applied holistically across the cloud environment

Control PaneGain confidence in controls and measure against regulatory obligations using a single, auditable view of compliance

Approaches to Cloud Adoption

7 | Sourced Confidential

Platform ApproachThis approach allows for a consistent control plane across the entire fleet of applications and helps centralise common functions such as networking, billing and security. This key element of cloud adoption is an essential part of Sourced’sCloud at Scale™ methodology

v

Workload ApproachThis approach sees the business unit developing a bespoke approach with minimal involvement from the organisation’s Central IT teams. This results in a deployment and operational philosophy tailored to the workload itself. This approach can also deliver short-term velocity but presents difficulties when the next wave of workloads begin their migration journey.

Cloud-Led Business Change

8 | Sourced Confidential

As part of the Cloud at Scale™ framework, Sourced identifies, designs and executes organisational change elements to better support the new cloud operating model.

A common outcome of this sees the introduction of a Cloud Centre of Excellence (CCoE).

Masthead Application

A masthead application should be chosen which allows the CCoE to maintain laser focus on building the most usable features first.

Can generate lessons learnt around security, compliance and technology

Application and supporting teams are supportive of change

Customer-Centric, meaningful to the success of your business
