- 12. How patterns form your Cloud Native solution 12 Patterns
- 13. 13 3/25/17 What are Patterns ? In software engineering, a software design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. Design patterns are formalized best practices that the programmer can use to solve common problems when designing an application or system. https://en.wikipedia.org/wiki/Software_design_pattern
- 14. 14 Some of the common patterns used in a Cloud Native solution
- 15. There are lots more , depending on your adoption of Cloud Native • The following is a summary of the common app patterns for Bluemix this is not a complete list but a starting point to level set on some basic architecture patterns that you build cloud native solutions with. • #1 Mobile to Service • Entry level pattern where the Mobile device either Native or Hybrid mobile directly communicates with a High Value Service. • #2 Mobile or Web to Backend for Frontend • Entry level pattern when a developer or project needs common logic or multi channel capabilities and abstracts with REST • #3 Server less Events • The developer is now extending the features of their application and needs to use server less features for async processing of integration of services. • #4 API Connectivity with Micro Services • The developer organization is moving to a Micro Service design and needs to manage the API releases and delivery of the services. • #5 Cognitive • The organization is starting to integrate Cognitive features and APIs • #6 Internet of Things • The organization is starting to consume data in flight and analyze it with data in store • #7 Async processing of Cloud Services • The organization is and development teams are starting to apply enterprise patterns for cloud service management, data offload and storage etc. • #8 Four Tier Forester Architectures • The organization is using mixed Public, Hybrid and Local and delivering complex Systems of Engagement and Systems of Record New Developers Web Developers Mutli Channel New Patterns early adopters Extending new business models Traditional IBM Customers Enterprise Cloud Behavior Startups Multi Team
- 16. A mobile app is a software application developed specifically for use on small, wireless computing devices, such as smartphones and tablets, rather than desktop or laptop computers. • Apple and Google have the largest market for Mobile Operating Systems • Often built using Native programming toolset with iOS and Android What is a Mobile App ?
- 17. In computing, a web application or web app is a client–server software application in which the client (or user interface) runs in a web browser • Evolving to true multi channel • Progressive Web Apps blur user interaction between the Desktop and Web • Users start journeys from multiple entry points What is a Web App ?
- 18. Those were the patterns you might recognize, we use them everyday Now we need to explain the patterns that make cloud native solutions become amazing and give software engineers the most flexibility to deliver
- 19. A BFF is tightly coupled to a specific user experience, and will typically be maintained by the same team as the user interface, thereby making it easier to define and adapt the API to the user interface requirements. • More flexibility for continuous delivery, no centrally controlled API • Enables digital channels to evolve quickly and to business needs • Contains transformational logic, integration logic, app facing API, possibly RPC in nature What is a Backend for Frontend
- 20. Micro services is a specialization of an implementation approach for service- oriented architectures (SOA) used to build flexible, independently deployable software systems. Services in a micro service architecture (MSA) are processes that communicate with each other over a network in order to fulfill a goal Individually managed and deployed and scale and are loosely coupled in nature Used for heavy lifting business logic What is a Micro service
- 21. IBM is releasing coverage for a number of key Cloud Native patterns for Interconnect 2017 Simple Web App + Cloud services (Java, Node, or Swift) 1 Simple Mobile + Cloud services (iOS, Android, Xamarin, Cordova) 2 Web and Mobile Frontends + BFF + Backend services Mobile clients: iOS, Android, Xamarin, Cordova BFF: (Java, Node, or Swift) x (Whisk action, CF App, Containerized server) 3 Managed API Service (API Connect) (Java, Node, Swift) 4 Microservice (container-based) Java, Node, Swift via predefined docker images Choice of orchestration framework 5 6 OpenWhisk-based Microservice Actions implemented in Java, Node, Swift Triggered by (whatever) service
- 22. Lets show these patterns in an end to end example Cloud native solutions evolve over time, often start out with just a few digital channels and a few foundational micro services, as engineers become comfortable with the software delivery model they extend and grow.

- 41. Backup : Pattern Characteristics What and how do these patterns work and what are the best cloud services for them to integrate with ? 41
- 42. #1 Mobile to Service Common App Pattern Design Swagger REST App SDKs Dependency Manager Mobile App SDK Code Gen Swagger Generated SDK System SDK Service SDK SDKs Backend for Front End Bluemix System SDks Enriched Service SDKs that cannot be code generated SDK Generation Public GIT Swift Package Manager Node Package Manager Maven Central (Java) IOS, tvOS, Mac (Swift) Android (Java) Cordova Hybrid HTML5 (JavaScript) Enable Code Gen SDKs Included API Connect and Mobile Foundation REST EndPoints Development System & Service SDKs System SDK Service SDK Core Object Store Authentication Weather Analytics Push Bluemix System level Services that are applied to App IPA/APK REST End Points APPIDAuthentication Analytics Bluemix Services Authentication Notifications App Analytics
- 43. Mobile to Service • This application pattern is often used to integrate backend services directly into mobile solutions, they are not worried about common code or web app. • This application pattern is only focused on delivering an app to the app store. • The developer wants to add a small number of services into their mobile app, but are not worried about code abstraction. • They do want services to be optimized for the mobile developer experience • They will want to use a dependency manager to pull in common code and service packages • They will want to use some common MBaaS patterns. • Authenticate with a trusted identity service OAuth, Google, Facebook, etc • They want to trigger a Push notification • They need to persist data seamlessly either connected or not connected • They need to store binary information like images or documents • They want to integrate some simple High value services, like Weather, Watson Dialog, Speech to Text, Text to Speech with Dialog • They want to collect analytics of the application usage
- 44. #2 Mobile and Web to Backend for Frontend Common App Pattern Design Swagger REST App SDKs Dependency Manager BFF SDK Code Gen Swagger Generated SDK System SDK Service SDK SDKs Micro Services Bluemix System SDks Enriched Service SDKs that cannot be code generated SDK Generation Public GIT Swift Package Manager Node Package Manager Maven Central (Java) Node.js + Express Swift + Kitura Java + Liberty Enable Code Gen SDKs Development System & Service SDKs Bluemix System level Services that are applied to App Runtime REST End Points Authentication AnalyticsWeb Browser Mobile System SDK Service SDK Core Object Store Authentication Weather Analytics Push APPIDAuthentication
- 45. #3 Mobile or Web to Backend for Frontend • This application pattern is a sign that a solution is maturing or a different set of requirements are needing to be met. Pattern #1 easily breaks as you scale the number of Service integration and when you need to do heavy integration logic which should not be done in the client OS runtime. • If a developer needs to deliver a Web experience or needs to abstract common business logic into an application server or they need to support multi channel app patterns. • The industry recognized way of doing this is with a REST endpoint that can be invoked from either a Mobile App or from a Web Application using Ajax. This approach is agnostic of Server runtime technology of Swift, Node or Java • Using SDK Generation we can easily generate an SDKs from these REST endpoints. • The requirement for service integration now means Bluemix services need to be integrated easily and seamlessly into a Server runtime not just within the Mobile Client. • As a developer I would expect to use the same SDK that I used in #1 Mobile pattern, it is managing the integration to the high value service for me. • As a developer I would expect to consume this SDK from the same Dependency manager for either a Mobile Client implementation as a Server Implementation.
- 46. #3 Server less Event Handling Common App Pattern Design Swagger REST Service SDKs Dependency Manager Open Whisk SDK Code Gen Swagger Generated SDK System SDK Service SDK SDKs Micro Services Bluemix System SDks for MBaaS Enriched Service SDKs that cannot be code generated SDK Generation Public GIT Swift Package Manager Node Package Manager Swift JavaScript Enable Code Gen SDKs Development System & Service SDKs Bluemix System level Services that are applied to App Runtime REST End Points APPIDAuthentication Analytics BFF System SDK Service SDK Core ObjectStore Authentication Weather Analytics Push APPIDAuthentication
- 47. Server less Event • A new emerging programming model is gaining interest in the market and its called Serverless programming or Event programming • This is a logical evolution for the cloud, you want to write a small snippet of code and integrate with a Bluemix service and not worry about the scaling and load of this code, its managed automatically by the Cloud Platform. • IBM had started to deliver on this need with OpenWhisk • Its still early days for IBM customers as they need to understand how it fits into existing programming model • Mobile App developers will want to use this as its enables simple and quick back ends to be created • We believe that it is complimentary to Pattern #1 and #2 and will be used to manage a wide range of Asynchronous processing. • The management tools around scale of development are not in place at the moment to allow large scale development teams to work with OpenWhisk, but this will mature quickly • What is clear is from Open Whisk is another Server Pattern focused on Swift and JavaScript. They need to access the same Bluemix Services as they would from a Mobile Pattern or Server Pattern. • Bluemix Mobile Services will extend the same System and Service SDKs from Mobile to be compatible with Server integration.
- 48. #4 APIC and Micro Services • As applications begin to scale in functionality or complexity and as more teams are formed to delivery the solution. Micro Service patterns are now becoming a common approach to delivering this within the Bluemix solution. • The solution architecture may start to use different runtime technologies to solve the business problem. Bluemix will offer three key language runtimes that are strategic. • Swift as a modern day systems language to enable a very fast execution and span client and server runtimes • JavaScript in the form of a Node.js implementation, is often use for fast implementations User Experiences and REST Services • Java is still heavily used in the industry and has a deep and rich component and package support. It is also has different characteristics to JavaScript as a Systems Language. So will not be going anywhere soon, even thou its 20+ years old. • Other Systems languages are starting to be considered as more experience of scaling micro service architectures are understood, including Go and C# • API Connect is IBM Bluemix offering to manage all these micro service teams into packages of API than can be managed and released, so they can be consumed in either Pattern #1 or Pattern #2 Bluemix App Patterns.
