3. 2023 SERIES OF EVENT New York May 16&17 Australia October 11&12 Singapore April 12&13 Helsinki & North June 5&6 Paris SEPTEMBER London November 15&16 June 28-30 SILICON VALLEY March 14&15 Dubai & Middle East February 22&23
5. Red Hat 100% Innovation 100% Open Source Application Connectivity
6. 5 Business needs driving demand for connectivity Businesses derive value when the cloud native applications can be accessed and consumed Application portability to support agility Flexibility to move apps across hybrid and multi cloud based on performance, resilience or data (stickiness/fluidity) requirements Combining Application and Network concerns Application Connectivity to/from services, across and off cluster combining network and application/business layer concerns Connecting API and event endpoints Application Connectivity for Microservices Architecture (MSA) and Event Driven Architecture (EDA) services Elements of Modern Application Connectivity Application Connectivity
7. Organizing for Application Connectivity Zaphod , Trillian, Marvin crew of Heart of Gold
8. CONFIDENTIAL Network/ DevOps Developer 7 Stakeholders have different Concerns Responsibilities of Application Connectivity Application Layer Business Layer Networking Layer ▸ Business value creation ▸ API Product ▸ Monetization ▸ Developer Portal ▸ API Analytics ▸ Authentication ▸ Authorization ▸ Rate Limiting ▸ Multi cloud application access ▸ DNS Global Load Balancing ▸ Multi cluster ingress ▸ Traffic Management Product Owner Application Connectivity
9. Governability Accessibility Security Discoverability App Connectivity Assessment Criteria
10. • Internal vs External access (aka North-South, East-West) • Internal traffic – inter vs intra domain • Synchronous request-response • Asynchronous event-driven • Performance requirements – throughput, payload • Resilience to failures G A S D Accessibility
11. • Encryption – at rest / in transit • AuthN – balance security, usability, scalability • AuthZ – zero trust, RBAC • Secrets management G A S D Security
12. • Developer engagement and experience • Human discovery – developer portal, service catalog • Machine discovery – service registry / routing • Schema registries (OAS, asyncAPI) G A S D Discoverability
13. • Policy -based governance • Manage the lifecycle • Deployment automation • Observability for performance • Analytics for usage insight G A S D Governability
14. Application Connectivity Solution Options
15. 14 Application Connectivity – Network concerns Network Concerns: Ingress and Egress
16. 15 Traffic to Applications in a Cluster Application Connectivity – Network concerns
17. 16 Traffic from Applications in a Cluster Application Connectivity – Network concerns
18. 17 Traffic to Applications in Multi-Cluster Application Connectivity – Network concerns
19. 18 Traffic to Applications in Multi-Cloud Application Connectivity – Network concerns
20. 19 Application Connectivity – Network concerns Network Concerns: Service to Service
21. Service Traffic in a Cluster 20 Application Connectivity – Network concerns
22. Service Traffic Across Clusters 21 Application Connectivity – Network concerns
23. Tunneling Across Clusters 22 Application Connectivity – Network concerns
24. 23 Application Connectivity - Architecture Application and Data Architecture Concerns
25. CONFIDENTIAL Designator Request-reply vs Event-driven 24 Source: Synchronous & ephemeral Low composability Simplified model Low tolerance to failure Best practices evolved as REST Asynchronous and persistent Decoupled Highly composable Complex model High tolerance to failure Best practices are still evolving Application Connectivity - Architecture
26. Application Connectivity – Integration Enablers 25 Solve integration problem by applying best practices out of the box. Even with microservice architectures. Integration Patterns Translate messages in multiple formats, and industry standard formats from finance, telco, health- care, and more Data Formats Simplify access to any endpoint such as databases, message queues, APIs. Connectors Application Connectivity - Architecture
27. 26 API Gateway Application Connectivity - Architecture
28. Service Mesh 27 Application Connectivity - Architecture
29. Data & Control Planes Opportunity for integration and consolidation 28 Application Connectivity - Architecture
30. “What is the answer to the Ultimate Question of Life, the Universe, and Everything?” Application Connectivity Matrix
31. Application Connectivity Matrix Accessibility Security Discoverability Governability Business layer Application layer Network layer
32. Application Connectivity Matrix Accessibility Security Discoverability Governability Business layer Application layer Network layer Define criteria for app connectivity requirements
33. Application Connectivity Matrix Accessibility Security Discoverability Governability Business layer Application layer Network layer Define criteria for app connectivity requirements Define connectivity options
34. Application Connectivity Matrix Accessibility Security Discoverability Governability Business layer Application layer Network layer Define criteria for app connectivity requirements Define connectivity options Evaluate best fit option
35. “The answer is 42, but what is the question?” Where to go from here…
36. • Embrace schema standards everywhere • Evolve developer portals for REST APIs to a unified Integration Hub Transfer Learnings • Ask how to interpret this in the context of your organization • Use the matrix as a tool to facilitate communication across teams Expand details in the matrix
37. Looking forward to the next chapter in the Hitchhacker’s Guide
