Supporting and Using EC2/CIMI on top of Cloud Environments via Deltacloud
Deltacloud is an open source project that abstracts differences between cloud providers and supports EC2 and CIMI APIs. It can be used on top of oVirt to provide EC2 and CIMI functionality. The Deltacloud server is installed and configured to use the oVirt driver. Then basic EC2 and CIMI operations like launching VMs, listing images, starting/stopping VMs can be performed by sending HTTP requests to the Deltacloud server endpoints. This allows existing tools that use EC2 or CIMI to manage VMs running on oVirt. Future work includes better support for additional oVirt and cloud API features.
Supporting and Using EC2/CIMI on top of Cloud Environments via Deltacloud
- 1. Supporting and UsingEC2/CIMI on top of Cloud Environments via Deltacloud Oved Ourfali Senior Software Engineer – Red Hat FOSDEM & Puppet Camp February 2013 1
- 2. Agenda Overview andMotivation Cloud APIs Using Deltacloud on top of oVirt via EC2 and CIMI Integration Installation EC2/CIMI examples Future Work Summary 2
- 3. Deltacloud Opensource Apache project Abstracts the differences between cloud providers Supports Deltacloud, EC2 and CIMI APIs Supports many cloud providers EC2 oVirt Eucalyptus OpenNebula OpenStack ..... 3
- 4. Deltacloud CIMIAPI EC2 API Deltacloud API Deltacloud Server EC2 driver oVirt driver Eucalyptus driver Amazon EC2 oVirt Eucalyptus 4
- 5. Motivation Heterogeneouscloud and virtualization environment Existing software working with common cloud APIs like EC2 Aeolus / CloudForms – cloud management software Synaps – CloudWatch implementation over EC2 API Heat (Openstack project) CloudFormation and CloudWatch support POC to support Deltacloud Automated scripts .... 5
- 6. Bottom Line If you work with EC2 / CIMI / Deltacloud API you can use it on top of many different cloud providers! 6
- 7. Cloud APIs DMTF CIMI API Cloud Infrastructure Management Interface http://dmtf.org/standards/cloud Version 1.0.0 was published in August, 29th, 2012, 1.0.1 in October Still new API, but aims to be the cloud standard API EC2 API – Amazon Elastic Cloud API Deltacloud API 7
- 8. CIMI API RESTbased API Main entities: Machines - configuration, image, template Volumes - images, configuration, image, template Networks – Configuration, Forwarding Group, Template Network Ports – Port configuration, Port Template 8
- 9. EC2 API API to Amazon Elastic Cloud, that allows to perform various actions HTTP GET/POST Endpoint—Entry point to act on Action—Action to perform on the endpoint Parameters—Request parameters 9
- 10. EC2 API Main entities: AMI – template that contains a software configuration Instance Type – instance hardware configuration Instance – compute resource EBS Volume – storage resource Networking entities (IP Addresses, NetworkInterface, Network ACL, Network ACL entries....) Region – different geographical locations where data centers reside Availability Zone – isolated from failures in other zones 10
- 11. Deltacloud API RESTbased API Main entities: Instances Images Hardware Profiles Realms Storage Volumes and Snapshots Networking Entities IP Addresses Load Balancers Firewalls 11
- 12. Using Deltacloud ontop of oVirt via EC2 and CIMI 12
- 13. oVirt Engine The oVirt engine is a large scale, centralized virtualization management platform Provides IaaS capabilities Every capability is exposed via rich API, UI, CLI and SDK 13
- 14. Deltacloud-oVirt integration oVirt Driver rbovirt REST API oVirt Engine 14
- 15. Install and Runthe Deltacloud Server Installing Deltacloud via GEM Run the following commands as super user: $ yum install rubygems gcc-c++ libxml libxslt libxslt-devel $ gem install rake deltacloud-core Running Deltacloud First set the API_PROVIDER in the following format API-URL; DataCenter-ID ; USER/ADMIN (default to ADMIN) Examples API_PROVIDER=”http://engine-server:port/api;dc-id;ADMIN API_PROVIDER=”http://engine-server:port/api;;USER Then, run the deltacloud daemon $ export API_PROVIDER=”http://ovirt-server:port/api;;USER” $ deltacloudd -i rhevm -f cimi,ec2,deltacloud 15
- 16. Install and Runthe Deltacloud Server Installing Deltacloud via RPM Run the following command as super user: $ yum install deltacloud-core-all Configure Deltacloud Set the DRIVER, API_PROVIDER and API_FRONTEND in /etc/sysconfig/deltacloud-core API_PROVIDER=”http://ovirt-server:port/api;;USER” API_FRONTEND=”cimi,ec2,deltalcoud” DRIVER=”rhevm” Running the Deltacloud service systemctl start deltacloud-core.service 16
- 17. Install and Runthe Deltacloud Server Admin API requests are DC-specific, whereas User ones are system- wide The API_PROVIDER can be changed by setting the “X-Deltacloud- Provider” HTTP Header on every request 17
- 18. Basic Operations -EC2 The following EC2 operations are supported when using Deltacloud on top of oVirt engine: Get Clusters (Availability Zones) Get Templates (AMI – Amazon Machine Images + Instance Type) Get VMs (Instances) Create new VM (Run Instances) Start VM (Start Instances) Stop VM (Stop Instances) Delete VM (Terminate Instances) 18

- 35. Future Work (oVirt/ Deltacloud) General Supporting VM configuration/instance type (not yet part of oVirt) Better mapping and support for networks Better mapping and support for storage volumes (Integrate into Deltacloud) Supporting VM Payload (Deltacloud) EC2 Supporting more EC2 options/actions (oVirt / Deltacloud) CIMI Supporting more CIMI options/actions/entities (oVirt / Deltacloud) Support updating resources (Deltacloud will need to support that and integrate with oVirt) 35
- 36.
