1 Cloud Computing A new kind of developers? Presentation by Nick Barcet July 2011

2 Cloud computing stack Salesforce.com, GoogleDocs, Office, etc... GoogleApps, Java, Azure, etc... Amazon, GoGrid, OpenStack, Eucalyptus, etc... Storage Network Xen KVM VMWare HyperV etc.. HP IBM Dell Lenovo etc.. 2 Presentation by Nick Barcet

3 Our Cloud offering Canonical's Ensemble Ubuntu Cloud Storage Network KVM, Xen LXC Orchestra (Bare metal provisioning) x86 ARM 3 Presentation by Nick Barcet

4 Speed of Innovation Cloud reduces development friction and costs Cloud adoption is being driven by developers Opportunity Access to latest technologies needed for competitive advantage rather than cost saving Reduces time to market and therefore increases Speed of innovation 4 Presentation by Nick Barcet

5 Second Wave of OSS Adoption First wave in 2000 focused on Linux and LAMP Winners were RedHat, MySQL Cloud represents Second Wave OSS innovating rather than imitating OSS is dominant in the cloud Opportunity Scalability of cloud requires free bits 5 Presentation by Nick Barcet

6 A fundamental change for developers 6

7 Developing Applications for the Cloud Infrastructure as a Service (IaaS) is not Virtualisation Not just porting existing Applications Application have control on the infrastructure Instances specialize themselves Develop on a cloud 7 Presentation by Nick Barcet

8 IaaS is not virtualization Virtualisation: Is not controllable by the application Each Instance require a specific disk image the term virtual machine regroups the notion of disk image and execution instance. Assumes old separation of work model between developer and operators 8 Presentation by Nick Barcet

9 Not just a porting exercise Current applications do not need to be ported anything that will run on a server can run in the cloud Application need to take advantage of the cloud Dynamic scaling Introspection Storage 9 Presentation by Nick Barcet

10 Old Habits Application Hardware Network Storage Dev Realm Operator Realm Assume that the infra is resilient Assume that the hardware scales vertically Assume that SQL is the only DB method, and that it will grow with the app SPOF and scalability are a data center issue 10 Presentation by Nick Barcet

11 New Habits Application Hardware Network Storage Developer Realm Applications can scale horizontally Application can spawns additional instances based on needs Any instance can fail, but you can always launch another one Data can scale horizontally too if you use NoSQL DBs for critical elements Applications can run across data centers (availability zones) Application control their storage 11 Presentation by Nick Barcet

12 APIs your application can use Amazon's API to control AWS leads the way to control : The infrastructure (EC2) Elemental/Object storage (S3) Block storage (EBS) Instances have access to meta-data and user-data Can query about environment Can learn about self Developers are now operators of the data center: DevOps 12 Presentation by Nick Barcet

13 IaaS instances particularities Instances are very similar to Object instances in programming A single Image can have multiple instances Can initialize themselves based on user-data passed to it Specialization of the instance is not linked to the image Storage is not linked to the image 13 Presentation by Nick Barcet

14 Instance, Image and Storage Example 1. Instance is created from a generic OS image with user data: Type: web front end Load balancer: lb.somewhere.com EBS: use disk web 2. Instance boots, receives and parse user data 3. Installs apache and configures itself 4. Attaches to ebs disk web 5. Informs load balancer that it is ready to receive requests 14 Presentation by Nick Barcet

15 Developing for the Cloud Requires to develop ON a cloud infrastructure Requires an instance OS that is compatible with the cloud Requires new way to orchestrate your applications in the cloud 15 Presentation by Nick Barcet

16 Using Ubuntu in the cloud 16

17 Ubuntu is free, maintained AND supported No additional fee to run your instance in public cloud Images are maintained, updates are public Mirrors are maintained within the environment Support is available as an option 17 Presentation by Nick Barcet

18 Ubuntu innovates Small, efficient base image Provides Amazon's API for most languages Same image can be ran on multiple clou Amazon Ubuntu Cloud Rackspace* Flexiant* KVM virtualisation environment Has cloud-init built in * Coming soon 18 Presentation by Nick Barcet

19 Cloud-Init Generic way to initialize your instance Works identically on multiple clouds Supports: Mounting EBS volumes Configuration management tools (ie Puppet) Modular and external scripting Package installation and configuration 19 Presentation by Nick Barcet

20 Ubuntu Images The #1 Public Cloud OS Amazon Web Services Images available since 2007 Believed to be the most widely deployed OS https://help.ubuntu.com/community/ec2startersguide Rackspace Cloud Images available since 2008 Confirmed as most widely deployed OS 20 Presentation by Nick Barcet

21 Using Ubuntu as the cloud 21

22 UbuntuEnterprise Clou d 22 Presentation by Nick Barcet

23 Ubuntu Cloud Ubuntu Oneiric Ocelot (11.10) Your Workloads UC Images Any OS OpenStack KVM, Xen or LXC Build your infrastructure as a service public or private cloud Based on OpenStack Supporting KVM, Xen & LXC hypervisors All components can be made highly available EC2, EBS and S3 compatible Ubuntu Server 23 Presentation by Nick Barcet

24 Ubuntu Cloud on your Laptop Single laptop deployment LXC based virtualisation tens of VM on a single laptop Your own Ubuntu Cloud on the Go 24 Presentation by Nick Barcet

25 Ubuntu Cloud in your Data Center Full data-center deployments Automated deployments with Orchestra (based on cobbler) and Ensemble Up to thousands of nodes Professional services can help make the infrastructure fully highly available 25 Presentation by Nick Barcet

26 Using Ensemble to orchestrate 26

27 Cloud deployments Deploying in the cloud the server is not the proper unit anymore How the service scales horizontally is the complexity Current configuration tool are clumsy as they still focus on servers Ensemble focuses on the services Creates servers when and where needed Hides the complexity of horizontal scalability in clean reusable formulas 27 Presentation by Nick Barcet

28 Ensemble Ensemble environment Cloud app Cloud app Cloud app Ensemble treats individual services as atoms that are described as formulas and can be instantiated one or many times. and dependency solver 28 Presentation by Nick Barcet

29 Ensemble Ensemble environment Load Balancer HAProxy Depends Provides Each formula (or atom) define dependencies and/or provides. Cloud app Cloud app Cloud app and dependency solver Provides Depends SQL Database MySQL 29 Presentation by Nick Barcet

30 Ensemble Ensemble environment Load Balancer HAProxy Varnish Depends Provides Multiple formulas can provide the same service and can be easily switched. Cloud app Cloud app Cloud app and dependency solver Provides Depends SQL Database MySQL 30 Presentation by Nick Barcet

31 Ensemble Ensemble environment and dependency solver Varnish Varnish Ensemble Relation Cloud app Cloud app Cloud app Ensemble Relation Ensemble maintains the relations between the services so that you don't need to care about the elasticity of your environment. Relations are to formulas what bounds are to atoms. 31 Presentation by Nick Barcet MySQL MySQL MySQL Services are loosely coupled but highly cohesive.

32 Ensemble Varnish Ensemble delivers service focused management through their life-cycle Ensemble environment Ensemble Relation Cloud app Cloud app Cloud app Offers the same simple rules to components of you infra as we do already for packages on your servers: dependencies, provides Adds the notion of dynamic relations between components and dependency solver* Ensemble Relation MySQL To provide you with simple automated elasticity that is easy to expand Working on your bare metal servers (through Orchestra*) as easily as on your favourite clouds (AWS, OpenStack*,...) 32 Presentation by Nick Barcet *coming soon

33 Next steps All development is public Communication is open Join Us IRC: #ubuntu-ensemble and #ubuntu-server on irc.freenode.net Launchpad: https://launchpad.net/orchestra Web: 33 Presentation by Nick Barcet
