Agility • Services evolve independently and at difference speeds • Easier to adopt new technology and evolve architecture • Enables continuous delivery Resilience • Use services boundaries for fault tolerance and isolation • Design for failure Runtime scalability • Stateless services designed for horizontal scalability • Services can be scaled independently Dev organization scalability • Easier to develop services in parallel • Smaller working set for each developer
- 12. APIs APIs allows for easy, quick and dynamic access to the business content of your application. API is a glue between Microservices. Attributes of an API Consumer driven Defined by Configuration Self Service Fast, Easy Fine-grained, Does one thing Focus on ease of consumption Easy access to Tasks / Data Business Asset Owner Service Intent: How can I effectively expose data / functions of my Business Asset Application Designer API Intent: How can I quickly and easily access specific data APIConsumerAPIProvider Applications A Consuming Application uses one or more APIs API’s An API productizes specific tasks of a service Multiple APIs can be “leveraged” from the same service Services A Service exposes a function of an Business Asset Multiple Services can be “derived” from a Business Asset Business Assets Can provide multiple functions Attributes of a Service Provider driven Defined by Coding On-boarding Managed Change, Stability Medium-Grained, Does several things Focus on connectivity, reuse Expose Functions for broad use

- 14. Standards: OpenStack & CloudFoundry Cloud related standards allow for interoperability, portability, automation and easier maintenace and development of the cloud applications. Applications Data Runtime Middleware O/S Virtualization Servers Storage Networking Software to manage compute, network, and storage for cloud The foundation of IBM’s IaaS interoperability Over 20k participants, 400 companies: Larger than Linux Built on a highly scalable distributed architecture The basis for IBM Bluemix De facto open PaaS platform Foundation established Dec. 2014; DEA Pools Router User Authentication & Authorization Cloud Controller Health Manager Service Gateway Apps Build Packs Service Connector Messaging Cloud Foundry BOSH Nova Compute node KeyStone Idenity service Swift Object Store Neuron Networking Glance Image Store Cinder Volume service Horizon Dashboard https://www.openstack.org/ https://www.cloudfoundry.org
- 16. Platforms: Bluemix & other PaaS PaaS aims at make cloud developer life easier. It handles many requirements automatically allowing developer to focus on coding business logic. An implementation of IBM's Open Cloud Architecture based on Cloud Foundry Delivers enterprise-level services that can easily integrate with your cloud applications without you needing to know how to install or configure them. Enables organizations and developers to quickly and easily create, deploy, and manage applications on the cloud. What is Bluemix? Bluemix features Bluemix services Containers Buildpacks Boilerplates Virtual Machines Monitoring Management Console API Management Auto scaling DevOps support Lots of services from IBM & 3rd parties Watson Mobile DevOps Web Applications IoT Integration Big Data Data Management Security Business Analytics Check the service catalog online: https://console.ng.bluemix.net/?direct=classic/#/store/cloudOEPaneId=store More information: https://console.ng.bluemix.net/
- 17. Containers Containers are relatively new concept allowing for convenient packaging your developments and „shipping” them to any destination. Run Any App Anywhere What is a Container? App A App A’ App B Bins / Libs Bins / Libs Bins / Libs Guest OS Guest OS Guest OS Hypervisor (Type 2) Host OS Server AppA Bins / Libs Bins / Libs Host OS Server AppA’ AppB’’ AppB AppB’ Docker Containers are isolated but share OS and, where appropriate, bins/libraries. It results in significantly faster deployment, much less overhead, easier migration & faster restart Docker VMs Image repository Image authoring Multi-container deployment Image signing Image Distribution Declarative model for deploy Container relationships Deploy/Manage containers Engine monitoring Image lifecycle management Business policy for deployment https://www.docker.com/
- 18. NoSQL & Languages New tools and programming languages increasing productivity, responsiveness and easiness of development. NoSQL Languages NoSQL (also translated as Not Only SQL) are the databases which allows you to store other structures than records/columns. GeoSpacial data 010101011 101010101 010101010 101010101 010101010 110101011 Documents Graphs Key-Value .swift

- 20. Methods Cloud development is about speed, agility and user experience. Waterfall is not enough anymore… Requirements Design Delivery OperationsGAP! GAP! GAP! How to „discover” & capture the real users requirements? Is the list of a 1000+ functional requirements useful? „ 400 features? No human would be able to use software with that level of complexity” - Dilbert How to assure that the developer’s understanding of requirements is aligned with the end user? How to include user feedback into development process? How to make sure that bugs are fixed almost instantly? How to make your solution „alive” and responsive to the new requirements? Design Thinking It is a formal method for practical, creative resolution of problems and creation of solutions, with the intent of an improved future result. It focuses on user and the way how the solution will be used rather then on requirements. Agile It is a group of software development methods in which requirements and solutions evolve through collaboration between self-organizing, cross- functional teams. It allows for bringing the user into the development process. DevOps It is a software development method that stresses communication, collaboration, integration, automation, & measurement of cooperation between development & operations team. It brings together people who build with people who run the solution. https://design.ibm.com/thinking.html https://en.wikipedia.org/wiki/Agile_software_development http://www.ibm.com/ibm/devops/us/en/
- 21. Hybrid Cloud Hybrid cloud demands portable architecture. Cloud apps should be able to run everywhere. Cloud is not a specific solution, platform nor product. Cloud is a new way in which IT solutions are delivered & consumed by Business. Private Cloud & IT Pros: • Full control • Advanced management • Strong security IBM PoV: Hybrid Cloud The best features from both worlds Maximization of investment Matching infrastructure with application Balance between security and elasticity Equalized investment (Capex vs. Opex) Shorter innovation cycles Pros: • Low entry costs • Pay-per-use, • Elasticity Off-premises / Public Cloud Dynamic Hybrid Hybrid Cloud+ Cloudbursting Cloudmigration Cloudintegration While developing for the cloud do consider:
- 22. Self service and Automation Cloud heavily relays on automation. Now developers can use many tools for automated provisioning, management and deployment of their code. One of the most well-known cloud infrastructure automation tools, Chef delivers configuration management and continuous delivery. By turning infrastructure into code, Chef helps cloud engineers and IT professionals automate infrastructure build, deployment, and management. Puppet is the configuration management system that enables cloud engineers and IT professionals to define the state of their IT infrastructure and then automatically enforces the correct state. Puppet automates time-consuming manual tasks. Some other tools are described here: https://blog.profitbricks.com/48-best-cloud-tools-for-infrastructure-automation/ Jenkins is an application that monitors executions of repeated jobs, such as building a software project or jobs run by cron. It helps with building/testing software projects continuously and monitoring executions of externally-run jobs. UrbanCode is a tool for automating application deployments through your environments. It is designed to facilitate rapid feedback and continuous delivery in agile development while providing the audit trails, versioning and approvals needed in production. IBM Cloud Orchestrator provides cloud management for your IT services, allowing you to accelerate the delivery of software and infrastructure. Based on open standards, it reduces the number of steps to manage public, private and hybrid clouds by using an easy-to-use interface. Bluemix Delivery Pipeline service automates builds and deployments, test execution, configure build scripts, and automate execution of unit tests. And many many more…
- 23. Is your application cloud centric/native/ready? If you are not sure… use Chaos Monkey – if your overall solution survives this encounter, you are good to go! https://github.com/Netflix/SimianArmy/wiki/Chaos-Monkey „Chaos Monkey is a service which identifies groups of systems and randomly terminates one of the systems in a group.”

Backing services :: Treat backing services as attached resources V. Build, release, run :: Strictly separate build and run stages VI. Processes :: Execute the app as one or more stateless processes VII. Port binding :: Export services via port binding VIII. Concurrency :: Scale out via the process model IX. Disposability :: Maximize robustness with fast startup and graceful shutdown X. Dev/prod parity :: Keep development, staging, and production as similar as possible XI. Logs :: Treat logs as event streams XII. Admin processes :: Run admin/management tasks as one-off processes
