Overview
SDP’s challenge
v3 was coming to end-of-life and Victoria’s had to decide whether to upgrade to version 4 (a major migration to a new cluster) or to go with another Kubernetes service provider.
SDP’s transformation
Salsa facilitated and supported ’s migration of the Single Digital Presence (and the 83 sites on the platform) from to Microsoft Azure’s service. The sites were all migrated successfully with no outages.
The outcomes
- SDP (including 83 production sites) migrated onto the new 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
Detailed case study
Below is more detailed information on the challenge, transformation and benefits.
SDP’s challenge — end-of-life OpenShift
v3 was coming to end-of-life and Victoria’s had to decide whether to upgrade to version 4 (a major migration to a new 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 .
SDP’s transformation — migrating 80+ sites
Salsa worked with our platform partners and the DPC/SDP team to migrate the 80+ websites, plus all the databases and filestores, on the SDP .
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 .
The outcomes — new supported platform
The outcomes delivered include:
SDP (including 83 production sites) migrated onto the new Azure
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 to manage different cluster configurations
Long-term cost savings for — 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)
