Outline

Context: the Contrail project

Contrail Virtual Execution Platform

Service Level Agreements and derived execution environments

VEP and OpenNebula

Contrail VEP/1 contrail-project.eu

Context: Contrail ProjectOpen Computing Infrastructures for Elastic Services

Contrail project objectives

Development of an integrated approach to virtualization o�ering

services for federating IaaS clouds and PaaS services on top of

federated clouds

Challenges

Integration of resources from multiple IaaS providers

Trust, service level agreements (SLA)

Elasticity (pay-as-you-go)

Scalability

Portability, interoperability

Security


VEP in the Contrail Software Stack

Contrail federation

SLA management

and enforcement

VEP: Virtual Execution Platform

IaaS


VEP sits between the

infrastructure and higher-level

layers: federation and SLA

management

VEP provides a high level

interface for application

management on heterogeneous

providers

VEP integrates SLA support


VEP and Contrail Federation Layer

Contrail federation

SLA management

and enforcement


IaaS

Each VEP is in charge of

managing applications on an

IaaS o�er on behalf of the

federation

Provides a high level uniformview of the infrastructure to thefederation

deploymentelasticity managementsnapshot

Participates to provider selection

by the federation

Monitors the application on the

infrastructure


VEP and Service Level Agreements

Contrail federation

SLA management

and enforcement


IaaS

VEP provides support for SLA

negotiation: terms which can be

enforced, guarantees about

resource availability, ...

VEP allocates resources in-line

with agreed SLA terms

(localization, a�nity,

performance, ...)

VEP in charge of the monitoring

con�guration

Negotiated SLAs translated in

VEP using Constrained

Execution Environments


VEP as an Independent Service

VEP can be exploited as an independent service

RESTful APIcan be exploited using a web browser

VEP manages applications as a whole

not just VMs

VEP application packaging: OVF format

OVF: Open Virtualization Format, a DMTF standardDistributed applications made of virtual machines (or containers),storage and networksOVF integrates

con�guration and deployment rules

means to contextualize virtual machines

VEP can exploit OVF application marketplaces


VEP as an Independent Component (2)

Typical lifecycle of a VEP application

Virtual system disk image handling, external �lesApplication con�gurationExecution environment speci�cationResource need evaluationResource allocation (constraint-aware)ContextualizationDeploymentElasticity managementCheckpointing (potentially in OVF format)

Advance reservation of resources

Performance management and resource allocation constraints

VEP Constrained Execution Environments


CEE: Constrained Execution Environment

A CEE de�nes a virtual infrastructure integrating:

resource templates for computation, storage and networkingconstraints on resource allocation

localization

a�nity

protection, security

performance

OVF applications are deployed inside CEEs

OVF virtual resources mapped on CEE resource templates andallocated in accordance with associated constraints

CEE de�nition

Ready-to-use CEEs can be exported by IaaS providers

ie. A golden VM cluster with high performance interconnect

Users can de�nes their own CEEs

Contrail project: CEEs are derived from negotiated SLAs

VEP and OpenNebula

The current implementation of VEP in Contrail project targets

OpenNebula

From OVF description

disk sections ⇒ VM images

virtual systems ⇒ VM templates

product sections ⇒ contextualization

Resource allocation

VEP needs a constraint-aware resource allocatornot integrated to OpenNebuladeveloped as an external service

Monitoring

monitoring data for SLA enforcement and federation managementexternal monitoring service to export OpenNebula monitoring data


Improvement Expected: VM Image Management

File references inside OVF disk sectionson the web

ie. OpenNebula marketplace

on image repositoryon IaaS image store

OVF supports disk delta

Application snapshots (in the future)

Need for close interaction with OpenNebula implementation to reduce

image management cost


Contrail VEP and standards

OVF (Open Virtualization Format) from DMTF: applicationdescription

no extension to OVF

CIMI (Cloud Infrastructure Management Interface) from DMTF

VEP API based on CIMIFuture: VEP server interoperable with standard CIMI clients

In the future

OCCI (Open Cloud Computing Interface) from OGF

to support other IaaS o�ersEGI

CDMI (Cloud Data Management Interface) from SNIA

for image management


Contrail VEP Software

First version May 2012

Current release (2.1): September 2013

integrating CEE supportRESTful API (DMTF CIMI style)

Full support of CIMI planned for the �nal release (2014)
