1 Composite Cloud Applications and Portable Topologies Vinothini Raju Bluemeric

2 Agenda 01 Composite Cloud / Modern Application Business 01 Drivers Continuous Delivery(CD) Monolithic App Limitations Microservices Containers Federated Clouds 02 Portability & Composability Importance of portability for CD New Portability Paradigm Current portability scenario Composability 03 Portable Topologies Service Templates Modernising Legacy App Modern Application delivery

3 01 02 Optimizing Operational Modern Application Cost Delivery Portability & Composability 03 Portable Topologies

4 Business Drivers for increased release velocity 01 Inside Out (Business Driven) - Multi-channel delivery - Hot patches Outside In (Market Driven) - Market Dynamics & Competition - Reconfigurable operational functions, processes and services

5 Continuous Delivery for release velocity 01 Isolated Incremental Updates Roll backs Reusable Services Architect 2 8 segments Polyglot team Package Portable Different Dev, Test & Production platforms Deploy Elastic Auto provision/ deprovision

6 CRM Monolithic Application Business Processes Order Processing Accounts management Service Management Database Application Modules Check customer status Check credit status Check Inventory Customer Create Invoice Check customer status Check credit status Check order status Application container Run time Inventory Order Invoice Check customer status Service Check service status Credit VM

7 Continuous Delivery - Monolithic App Limitation Tightly integrated - Updates & rollbacks require 01 complete application deployment Architect 2 8 segments Deeper application knowledge Package Portable Different Dev, Test & Production platforms Deploy Auto-provision - Provisioning VMs not optimal

8 Agile Continuous Delivery 01 Microservices Architect 2 8 segments Package Containers Deploy Cloud

9 Agile SOA - Microservices Micro business responsibility Slice Mega microservices Interoperable Isolated processes Smart app, dumb pipes Mono Integrate Poly/distributed

10 Containers What it can pack & compose? Right from middleware Application Data Runtime Middleware OS Virtualization Server Can be reused, stacked & composed Easy to pack without adjusting the component to fit Suitable for increased delivery volumes Storage Networking

11 Federated Cloud Federated Cloud Cloud is about infinity Hybrid is about flexibility PaaS External Services Federation is about variety IaaS

12 Refactored CRM App IaaS Check customer status PaaS Check Inventory Service Request Management Customer Data Service Inventory Data Service Accounts management Order Processing Check credit Check order status Credit Data Service Create invoice Invoice Data Service Order Data Service Service Broker SaaS Reusable Components Independently testable Integrates with external services Different components hosted on different clo Granular scaling

13 01 02 Optimizing Operational Modern Application Cost Delivery Portability & Composability 03 Portable Topologies

14 Importance of portability for CD PaaS Develop Test IaaS Simulate production like env Flexible Development env (Mac OSX, Windows, Linux) Local Design Deploy IaaS

15 Portability & Composability so far Portability Image Infrastructure Scalability, HA, Security & Monitoring policies Application Composition Image based Modified Provisioned Provisioned & Configured Modified Static Application based NA Provisioned Provisioned & Configured NA Deployment Application (across PaaS) NA Auto- Provisioned by PaaS Provisioned & Configured Modified Partially dynamic

16 Portability - A new paradigm Across Cloud Layers PaaS / Application IaaS / Platform Operating Systems Portability Composability Across Vendors

17 Compositions are maturing dynamic Run time deployment Deployment static Packaging 17

18 01 Dynamic composition is a great vision of a distant future.

22 Modern Application Lifecycle PaaS Develop Test PaaS IaaS Service Template Local Design Deploy IaaS

23 Modernizing legacy applications Containerize Monolithic Service Templates UnContainerize Portable Application Can be composed along with micro services
