This focused on reviewing the current implementation and usage of the Cloud against the 6 pillars. We assessed against the following:
‍
1. Operational excellence: how systems are monitored and managed to provide insights that give an understanding of improvements and a way to prioritise.
‍
2. Security: security strategies adopted, security architectures that are in place, controls and reporting around access controls, data protection and continual monitoring.
‍
3. Reliability: how recoverable services are and how they are designed, scalability to meet demand, ability to provide a highly available and uninterrupted service.
‍
4. Performance efficiency: how infrastructure is utilised, design principles surrounding technology choices as well as the ability to scale and optimise through insights.
‍
5. Cost optimisation: ability to reduce expenses, have insights, budgets and report, right-size infrastructure, optimise appropriately and drive down overall cloud costs.
‍
6. Sustainability: an understanding of system design in regards to optimising energy efficiency, reducing waste and leveraging sustainable practices. 

‍In order to deliver the new version of the application repeatedly across tenants, Appvia provided a GitOps continuous deployment solution that leveraged Gitlab, Helm and Flux. This provided a repeatable but agnostic way to deliver their containerised applications across Kubernetes cluster environments. Additional security layers were added to ensure the software supply chain was not tampered with and that the application was meeting the security requirements of the business. Appvia built CI pipeline fragments (which are reusable steps within a CI pipeline), that covered building and pushing containers and helm charts to repositories, running tests in ephemeral environments, scanning docker images and ensuring the integrity of built images. Flux then pulled the updated components into the clusters for a fully declarative approach.

‍Appvia provided a tightly integrated AWS billing solution, that leveraged live data and tagging information, (enforced by policy and implemented via the landing zone). To enable deep cost insights into the Cloud costs. Dashboards were provided to help organise the information into organisational views such as by application, by line of business, by service and more. This allowed for the relevant role-based access controls to be put in place, so relevant teams can keep track of their spend and use the data to drive down cost savings.
