Transformation Is Multifaceted And Multi-cloud3

What Is A Microservice?Variant of SOA architectural style that structures an application asa collection of loosely coupled servicesServices should be fine-grained and use lightweight protocolsDesigned to sufficiently decompose the application in order tofacilitate agile application development and deployment4

SUSE Containerand ApplicationPlatformsCommunityInvolvement19

SUSE Is Committed To Cloud FoundryAs a long-time supporter of Cloud Foundry, SUSE contributes to the project and its Foundation in manyways: Platinum member of Cloud Foundry Foundation SUSE Cloud Application Platform is a certified distribution Originator and Project Lead for CF Containerization Originator and Project Lead for Stratos Early adopter and influencer of Project Eirini20

CF ContainerizationPackages Cloud Foundry Application Runtime (CFAR) as containers instead of virtual machines,allowing CFAR to be deployed to Kubernetes Originated at SUSE; SUSE is project lead Eliminates requirement for BOSH Allows your organization to standardize onKubernetes as your hosting platform Much smaller CFAR footprint than VM baseddistribution. (Min 32GB vs 128GB.) Easy to start small and scale up withoutbreaking the bank21

StratosWeb-based UI for managing Cloud Foundry (and now, Kubernetes). It allows users and administratorsto both manage applications running in the Cloud Foundry cluster and perform cluster managementtasks. Originated at SUSE; SUSE is project lead Single pane of glass dashboard and metrics Aggregate multiple CF instances: SUSE-CAP,PCF, open source, or any other View of underlying Kubernetes infrastructure Customizable branding and styling Extensible for adding additional integrations22

Stratos provides Multi-cloud ManagementCentralized management of clusters and workloadsAmazon EKSGoogle EKSMicrosoft AKSOn-prem K8sSelf-managed K8s onpublic cloud IaaS23

Project EiriniEnables pluggable scheduling for CFAR (allows operators to choose whether CFAR should use Diegoor Kubernetes to orchestrate application container instances) SUSE announced forthcoming support forEirini at CF Summit EU in October 2018 SUSE-CAP 1.4 is the first Cloud Foundrysoftware distribution to support Eirini Run Cloud Foundry applications natively inKubernetes Same Cloud Foundry developer experience Familiar Kubernetes operator experience24

Cloud Foundry Application RuntimeA code-centric platform that simplifies the life of developers. It takes your code, written in any languageor framework, and runs it on any cloud. One step command to containerize, deploy,and manage an application Automatically identifies and pulls in languagelibraries and frameworks via buildpacks Open source service brokers automaticallycreate and bind services to applications Automates application lifecycle managementby assigning appropriate resources, managingrouting, load balancing, scaling, and more25

Introduction to CF - SUSE Cloud Application PlatformIMPORTANT! This Hands-On session assumes that you have a running deployment of SUSECloud Application Platform and SUSE Stratos in order to follow the lab below.Deploying your first app manuallyClone the Dora App git clone https://github.com/rbejarano80/dora.git cd doraPush the dora Application cf push dora -b ruby buildpack -s sle15 -k 128m -m 36m --random-routeThis deployment will Fail - find out why by looking into the logs: cf logs dora --recentNotice the ERR shows not enough disk - redeploy with a larger disk size: cf push dora -b ruby buildpack -s sle15 -k 512m -m 36m --random-routeThe Application now will be deployed properly - Take note of the routes section at the bottom ofthe output access the application with a browser or with curl, ie: curl dora-surprised-possum.scf.geeko.landHandling currently running applicationsList the runnign applcations in our designated space: cf appsGet more details on your specific app dora cf app doraConnect to your appliation via SSH cf ssh dora (close with exit )Check the logs generated by the app dora cf logs dora --recentDelete the previously deployed App
