Into the cloud, you better fly by sight

One aspect is crucial, when preserving IT value through cloud-friendly migration of legacy applications: Transparency. You need full visibility on the source application landscape, on the migration process, and on the target cloud environment. Without transparency, your effort, time targets and also quality go overboard –- you’ll experience an agonizing blind flight with a high risk of accidents. In the keynote, I will show the most important measures and tools with which you can create the visibility that has proven decisive in our many hundreds of migration projects.

1. Cloud Native Migration INTO THE CLOUD, YOU BETTER FLY BY SIGHT Dr. Josef Adersberger
2. 1. Overrun of costs, efforts, timelines 2. Unexpected severe portability issues 3. Wrong technology decisions 4. Lack of security, privacy & compliance 5. ... Things can go terribly wrong on a cloud native journey
3. 3 A successful cloud migration ❏ In time: All 600+ web applications migrated to public cloud and in production within 4 years ❏ In budget: no overrun & strong business case generated ❏ Full advantage: All applications security-hardened and modernized to containerized 12-factor-apps, higher availability, more agile teams
4. 4 #1 LESSON LEARNED: No blind flight into the cloud

9. 9 Business Intelligence (Tableau) ❏ What technologies are used? ❏ What libraries are integrated in which version? ❏ What protocols are used? ❏ How much code? ❏ How much over-complex code? ❏ How many code anomalies per LOC? ❏ ...
10. 10 Graph Search & Analysis (neo4j) ❏ Which deployment units contain a specific class? ❏ What deployment units have a transitive dependency to a specific class or library? ❏ What are all code-level dependencies between our applications? ❏ ...
