To achieve its objectives, we decided to adopt a multi-cloud approach. We choose to run an active-active architecture across multiple cloud providers, such as AWS and Microsoft Azure, to improve system resiliency and avoid potential service disruptions caused by a single cloud provider's failure.

Incorporating DevOps practices, we integrate CI/CD pipelines into their software development lifecycle. We leverage various tools like Jenkins or GitLab CI/CD to automate the build, testing, and deployment processes. By automating these steps, our partner can achieve faster feedback to users and ensure that software changes are deployed consistently and reliably.

To enhance security and manage secrets, we implemented a vaultsystem from HashiCorp. This ensures that sensitive information such as API keys, passwords, and other credentials are securely stored and accessed by authorized users and services only.

To manage infrastructure as code, we adopted Terraform, an open-source tool that allows us to define their cloud infrastructure in declarative configuration files. This ensures consistent and reproducible deployments across different cloud platforms.

Moreover, we utilized Ansible for configuration management, enabling them to automate the setup and maintenance of their servers, services, and applications. This reduces manual errors and ensures consistency in their deployment environment.
