This document discusses different cloud platforms for hosting Grails applications. It provides an overview of infrastructure as a service (IaaS) models like Amazon EC2 and shared/dedicated virtual private servers, as well as platform as a service (PaaS) options including Amazon Beanstalk, Google App Engine, Heroku, Cloud Foundry, and Jelastic. A comparison chart evaluates these platforms based on factors such as pricing, control, reliability, and scalability. The document emphasizes that competition and changes in the cloud space are rapid and recommends keeping applications loosely coupled and testing platforms using free trials.

- 5. 5 “Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of essential characteristics, deployment models, and various service models. “ (according: National Institute of Standards and Technology (NIST)) Definition
- 6. 6 Essential Characteristics • On-demand self-service • Location independent resource pooling • Network access • Rapid elasticity - Scale Up/Down - on demand • Measured Service
- 7. 7 Cloud Delivery Models • Infrastructure as a Service (IaaS). • Platform as a Service (PaaS) • Software as a Service (SaaS)
- 8. 8 Cloud Deployment Model • Private cloud. • Community cloud. • Public cloud. • Hybrid cloud

- 13. 13 PaaS + IaaS = DevOps DevOps "DevOps" is an emerging set of principles, methods and practices for communication, collaboration and integration between software development (application/software engineering) and IT operations (systems administration/infrastructure) professionals Automating as much as possible !!!
- 14. Amazon EC2 14 • Since 2006 – proven • Very Flexible • Lot of add-on services S3, SNS, SES, RDS….. • Lots of architecture possibilities • APIs for each service • Console and tools • Region and zones • Scale with Elastic Load Balancer.
- 15. Amazon Beanstalk 15 • New service but evolving fast • Not so friendly… • Only one application on instance • Scalable using Elastic load balancer • SQL on RDS that is expensive • Tomcat 6 or 7 • Configuration options • Not efficient logs
- 16. Amazon 16 Also give Free training
- 17. 17 Google App Engine • Grails Plugin. • Limit support for JEE • No Hibernate support – use JPA annotation for GORM • Uninstall Hibernate • Annotate all GORM classes • read only file system • Auto session management • Services: Mail, task queue, Image processing • Sticky vendor
- 18. Heroku • Build for Ruby • SalesForce.com company • Free account • Grails support with buildpack tool to push and build grails application from GIT. • Grails Heroku plugin • no support for session affinity or clustered sessions 18
- 19. Heroku – quick start • Create account • Install command line client • Create application • Install plugins • Set local GIT • Create Heroku application • GIT push 19
- 20. Cloud Foundry • VM ware company the Grails sponsors. • Still Beta. • Public, Private , Micro(local). • Local run on VMware Player • Install command line tool or STS plugin (Ruby + vmc • Vendor agnostic • Many platforms and frameworks support. • Sticky session 20
- 21. Jelastic • Java Paas layer for hosting • Production since April 2012 • 5 vendors in different location and different pricing • User friendly java Paas • Application servers, SQL & noSQL selection • War or Maven deploy. 21
- 22. CloudBees • End to end PaaS • Development & runtime services • Provider agnostic service 22
- 23. CloudBees -DEV • Continuous Integration as part of the cloud infrastructure 23
- 24. CloudBees -RUN • Vendor agnostic • Tomcat + mysql 24

- 27. Take outs • Competition and changes are fast • Better keep “loosely coupled” • PaaS solutions are young… • Price comparison is difficult / unknown • Support and documentation • Tools and API • Security and access • Use the free trail to test 27
Editor's Notes
- the cloud infrastructure is operated solely for an organization. it may be managed by the organization or a third party, and may exist on or off the premises. the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations the cloud infrastructure is made available to the general public or a large industry group, and is owned by an organization selling cloud services. the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting).
