Cloud Migration Project 8 Cloud Evolution original PaaS provider didn‘t meet expectations Google as new strategic cloud provider taking the next step, instead of „lift & shift“

Cloud Migration Project 9 Project Scope & Setup evolve applications to GCP timeframe: March to September core team / platform team / development teams

Cloud Migration Project 10 Architecture Role & Challenges Tech How can we map our strategy to the GCP? How can we support our development teams? What should the GCP base setup look like? EA What exactly are “all applications”? How critical are they? Which interfaces will be affected? How can we track progress / verify that we are on target? How can we assign costs to applications?

EA support for a headstart Which applications are in which environments? How are the applications interconnected? Which identifier should be assigned to cloud assets? Who is responsible for the cloud migration? Cloud Migration 12

Becoming a partner in the cloud migration project Which application are in which environment? 13 Identification of relevant application ➢ Environments of applications ➢ Business criticality of applications ➢ Experience of teams migrating applications Maintaining LeanIX application factsheet as essential process step to acquire cloud resources

Integrating interfaces on the fly How are the application interconnected? 14 Applications Interfaces and Relations GraphQL DEV Kafka INT Kafka PROD Kafka Topics

Integrating interfaces on the fly How are the application interconnected? 15

Keeping the pace with EA Which applications are already in the Google Cloud? Which services do the applications use? Are all applications using compliant service regions? Have we achieved our goal to use more managed cloud services? Cloud Migration 16

Using the Integration API to import cloud services into LeanIX 17 17 Cloud Services Service Regions Service Environments Integration API Billing Data Billing Data Cloud Service Exporter Next Version

Keeping track of the migration progress 18 Monitoring of migrated applications ➢ Evolvement of best practices ➢ Data transfer to non compliant data regions ➢ Getting the right support for managed services Reducing the workload of maintaing factsheets as EA acceptance boost

Turning from a sprint to a marathon How do my costs evolve in the new cloud? Are the number of incidents lower than before? What are next candidates for migration? Are we able to implement more business requirements than before? Cloud Migration 19

Using the built-in integration to enrich application factsheets 20 Multi Clouds Application ID Cloud Assets with tagged Application ID Application Data (Cost Center, Apptio Business Service) Application Cost & List of Cost Centers and Apptio Business Service

Stay on top of things 21 Evaluation of cloud based applications ➢ Potential of cost reduction ➢ Compatibility with future business needs ➢ Reduction of technical complexity Using the best of all IT management tools as a major driver for business IT alignment

22 We have the data, but we need more possibilities to show them! ➢ Analysis of relations ➢ Visualisation of data
