  2. 2. Cover w/ Image Agenda ■ Why move my .Net applications to the Cloud ? ■ A map of Cloud-native patterns ■ How to apply these patterns to your .Net Cloud Native apps ■ Demo
  3. 3. On premise Data Centre .Net Applications Why move my .Net applications to the Cloud ? Databases Transformation path (expected) ● Windows 2008/2012 -> Windows 2019 / Linux ● ASP.Net 3x -> ASP.Net 4.5 -> .Net Core ● SQL Server DB ->> SQL / NoSQL Cloud data sources ● Windows / .Net technos >> polyglot platforms ● … erase other technical and process debts Reason #1: deal with the legacy workloads - Reduction in Operational Costs - Framework EOLs - Improving SLA
  4. 4. Why move my .Net applications to the Cloud? How do you deal with? ● Hardcoded IPs? ● Hardcoded credentials? ● Discovery of other services? ● Existing pipelines? Should you: ● Ask other teams to write .Net code ? ● Rewrite the other applications ? Reason #2: make your applications discuss with other applications: - Inherited from business acquisitions - new developments - To integrate with 3rd party components Java applications .Net Applications
  5. 5. Cloud-native patterns overview (... when you need to redesign things)

A map of Cloud Native patterns Design Security Behavior Team ● 12 factors ● API first ● Contract ● Stateless ● Circuit breaker ● Domain-Driven Design ● Client LB ● External Config ● Service Discovery ● Asynchronous ● Data service abstractions ● Vault ● Continuous Update/Patch ● Threat Detection ● Credential/Certif icate Rotation ● Single Sign-On ● Instantaneous scale-up/down ● Continuous upgrade/patch ● Event-driven ● Disposable ● Observable (SLO/SLI) ● Resiliency ● Product centric ● Observability (SLO/SLI) ● Small iterations ● CI/CD ● Chaos Engineering ● Site Reliability Engineering
