Managed and Co-managed Service Strategy
Orange Business Services can flexibly support Customers in different ways for their use of the cloud.
The Fully Managed option is a model by which OBS takes care of all the deployment, the supervision, the operations of the workloads of the Customer. The Customer has the responsibility to provide a fully tested workload. This model is best suitable for the stable applications and workloads with a low amount of modifications and transformation. It provides operational efficiency.
The Co-managed model, whereby the Customer and OBS share the responsibilities the deployment, the supervision, the operations of the applications and workloads. In this model, the Customer is taking care of the development and testing of the application. The Customer can propose deployment templates thanks to change process. OBS is responsible for the monitoring and maintenance 24 x 7 inclusive of non-business hours and non-business days and / or 8 x 5 for less critical workloads. Both collaborate using a Git referential, a Continuous Integration and Deployment Chain and a shared tooling for monitoring, logging, alerting, dashboards and communication. The Service Reliability Engineers will take part into Customer’s development team to contribute to the readiness of the operability, and its continuous improvement. This model is an efficient compromise for getting the development agility, transformation of the application and frequent push to production, while keeping an efficient service assurance through delegation to OBS and preserving the critical development resources towards most value-added development tasks. The Co-managed model can be complemented with Cloud Center of Excellence or Cloud Expertise.
The Selfcare model, whereby the development team of the Customer is fully responsible for the development, the deployment, the supervision, the operations of the workloads. In that model, OBS can propose professional services to the Customer, typically under the form of a Cloud Center of Excellence or Cloud Expertise to help the Customer setting the DevOps pipelines, tooling, landing zone and build to run activity. In this model, OBS can also propose the Service Reliability Engineering. This model is best suitable for applications and workloads subject to intensive development and modifications with frequent deployments to production. Drawback is that the developers need to be mobilized in 24×7 and need to take care for some operational aspects during the whole project life.
Each customer case is specific, yet the Co-managed model is taking momentum especially with the use of Cloud Native functions / PaaS functions of the clouds.
The service description in this document applies to both full managed and co-managed services. During the presale or consulting phase, the Customer and OBS will agree to the model of managed services required and adapt the RACI accordingly. This may vary from one Customer to another, from one service or application to another.
