Overview

SDP’s challenge

OpenShiftExternal Link v3 was coming to end-of-life and Victoria’s DPCExternal Link had to decide whether to upgrade to version 4 (a major migration to a new OpenShiftExternal Link cluster) or to go with another Kubernetes service provider.

More about the challenge

SDP’s transformation

Salsa facilitated and supported amazee.ioExternal Link ’s migration of the Single Digital Presence platformExternal Link (and the 83 sites on the platform) from OpenShiftExternal Link to Microsoft Azure’s AKSExternal Link service. The sites were all migrated successfully with no outages.

The outcomes

  • SDP platformExternal Link (including 83 production sites) migrated onto the new AzureExternal Link platform
  • Protection from security and maintenance issues due to end-of-life lack of support
  • New infrastructure allows for greater separation between production and non-production workloads

SDP’s challenge — end-of-life OpenShift

OpenShiftExternal Link v3 was coming to end-of-life and Victoria’s DPCExternal Link had to decide whether to upgrade to version 4 (a major migration to a new OpenShiftExternal Link cluster) or to go with another Kubernetes service provider. The other options they were looking at were AWS EKS or Azure AKS. In the end, DPC chose Microsoft Azure AKSExternal Link .

SDP’s transformation — migrating 80+ sites

Salsa worked with our platform partners amazee.ioExternal Link and the DPC/SDP team to migrate the 80+ websites, plus all the databases and filestores, on the SDP platformExternal Link .

amazee.ioExternal Link created migration scripts to automate the migration process. These scripts interacted with various APIs to ensure that the destination cluster provisioned necessary resources to run the production workload, and handled migrating file systems and databases. The migration team communicated with website stakeholders to provide windows for validation testing and then proceeded to update DNS when required.

In total, over 1TB of data (file systems and databases) needed to be moved. The biggest file size for a single website was 29GB. The sites were smoothly migrated with no outages.

Part of the project also involved change management, including updating collateral/documentation and training the Salsa and SDP teams on the new Azure platformExternal Link .

The outcomes — new supported platform

The outcomes delivered include:

  • SDP platformExternal Link (including 83 production sites) migrated onto the new Azure platformExternal Link

  • Protection from security and maintenance issues due to end-of-life lack of support

  • New infrastructure allows for greater separation between production and non-production workloads

  • More flexibility for DPCExternal Link to manage different cluster configurations

  • Long-term cost savings for SDPExternal Link — AKS can scale compute so part of the infrastructure can be ‘put to sleep’ when not in use (this will be further optimised in 2022)
