Platform-as-a-Service (PaaS) is a technology designed to make devops easier and allow developers to focus on application development. The PaaS takes care of provisioning, scaling, HA, and other cloud management aspects. Apache Stratos is a PaaS codebase developed in Apache and designed to create a highly productive developer environment while also supporting powerful deployment options. Integration with the Docker platform, CoreOS Linux distribution, and Kubernetes container management system bring more scalability and flexibility to a Apache Stratos PaaS. This session will include installing and deploying sample applications using Docker,CoreOS and Kubernetes, and a walkthrough on how it can be extended to support new application containers. It will also include a demonstration of app deployment, provisioning, auto-scaling, and more.

- 3. ** Agenda ๏ Introduction to Apache Stratos ๏ Apache Stratos Architecture ๏ Apache Stratos 4.1 – Containerization and Composition Release ๏ Introduction to CoreOS, Kubernetes ๏ Apache Stratos with Docker ๏ Why Composite Application Support? ๏ Discuss few Apache Stratos features - Multi-factored auto scaling - Scalable and dynamic load balancing - Smart policies - Cloud bursting ๏ Demo - Docker, Kubernetes with autoscaling
- 4. ** Apache Stratos ๏ Apache Stratos is a highly-extensible Platform-as-a- Service (PaaS) framework that helps run Apache Tomcat, PHP, and MySQL applications and can be extended to support many more environments on all major cloud infrastructures ๏ Stratos initially developed by WSO2 and last year donated to Apache Software Foundation ๏ After successfully complete the incubating process Stratos now graduated as Top Level Project
- 5. ** Apache Stratos Layered Architecture
- 7. ** Apache Stratos L1 Architecture for VM based Cartridges
- 8. ** ๏ Application Composition ๏ Containerization ๏ Docker based cartridge support ๏ integration with CoreOS ๏ integration with Kubernetes ๏ integration with flannel ๏ integration with discovery service and build in docker registry support Apache Stratos 4.1 – Containerization and Composition Release
- 12. ** What is Kubernetes? ๏ Kubernetes is a platform for hosting Docker containers in a clustered environment with multiple Docker hosts ๏ Provides container grouping, load balancing, auto- healing, manual scaling features ...etc ๏ Project was started by Google ๏ Contributors == Google, CodeOS, Redhat, Mesosphere, Microsoft, HP, IBM, VMWare, Pivotal, SaltStack, etc
- 14. ** Apache Stratos L1 Architecture for Docker based Cartridges
- 15. ** Stratos Architecture with Docker Support
- 16. ** Why Composite Application Support? ๏ Real world application are complex and required multiple heterogeneous service runtimes (Cartridges) to host the application ๏ These Cartridges may have dependencies to each other - startup order - dependency ratio - dependent scaling - termination behaviors - data sharing ๏ Capable of creating Cartridge group and it provide more flexibility to handle group behaviours such as group scaling, load balancing..etc ๏ Capable of creating blueprint of an application runtime by using simple structured json payload
- 19. ** What is it? ๏ Scaling algorithm can use multiple factors. such as - Load average of the instance - Memory consumption of the instance - In-flight request count in LB Multi-factored Auto Scaling
- 20. ** ๏ Capable of predicting future load - Real time analysis of current load status using CEP integration - Predict immediate future load based on CEP resulting streams - Predicting equation s=ut + ½ at2 - s=predicted load, u=first derivative of current average load, t=time interval , a=second derivative of current load Why should one care? ๏ Maximise resource utilization ๏ Easy to do capacity planning ๏ Dynamic load based resource provisioning ๏ Optimizing across multiple clouds Multi-factored Auto Scaling...
- 21. ** What is unique about Stratos ๏ Cartridge based LB model ๏ Can bring any third-party LB - HAProxy, nginx, AWS ELB - As easy as plugging into LB extension API Scalable and Dynamic Load Balancing
- 22. ** What are the smart policies? ๏ Auto scaling ๏ Deployment Auto scaling policy ๏ Define thresholds values pertaining scale up/down decision ๏ Auto Scaler refer this policy ๏ Defined by DevOps Deployment policy ๏ Defined how and where to spawn cartridge instances ๏ Defined min and max instances in a selected service cluster ๏ Defined by DevOps based on deployment patterns Smart Policies
- 23. ** What is it? ๏ Expanding/provisioning application into another cloud to handle peak load. Why Should one care? ๏ Resource peak time can be off-loaded to third party clouds/resources What is unique about it? ๏ Can off-load to any cloud - Private, Public and Hybrid ๏ Whole application can replicated into bursting cloud with all configuration ๏ Can migrate application into another cloud without downtime Cloud Bursting
