Migrating a cloud-native application to Google Cloud
Secure connection and extended migration
Since the application in Google Cloud has a secure connection to the on-premises data center and is only intended to be accessible internally, the migration of the application went beyond a pure 1:1 migration between the cloud environments. In addition, minimizing operational effort and costs were key objectives of the migration. Based on these requirements, Accso created a concept that selected the optimal operating environment for the application containers and enabled a secure connection to the network.
Cost efficiency through a serverless approach
A serverless approach enabled significant cost reductions, as costs for the application containers are only incurred when they are actually used. The cost savings are particularly noticeable in test environments that are used infrequently. In addition, operating costs were reduced compared to the use of virtual machines or Kubernetes. The additional complexity of connecting applications running in Google-managed services to the ZDF network was solved by the network concept that was created.
Optimized migration and future flexibility
The existing application containers were migrated to Google Cloud with only minor adjustments. Any remaining dependencies on specific cloud providers were eliminated to make future cloud migrations even easier. Parallel operation of the application in the previous environment and in Google Cloud was enabled. This allowed the switch to Google Cloud to be carried out with minimal risk.
