Eucalyptus 3

“Scalability and reliability have been significantly improved in Eucalyptus 3”

Gregor von Laszewski Indiana University

A common set of APIs

National Institute of Standards and Technology in April 2012

There are many cloud products in the market place, but NIST has determined Eucalyptus Enterprise Edition is the only IaaS cloud management software currently on the market that is built open source and supports private and public cloud infrastructure.

3 approaches to IaaS

CLOUD APPROACH

DATACENTER APPROACH

CLIENT/SERVER Scale-up Closed source Monolithic binaries

WEB Scale-out Open source Stacks & distros

Infrastructure Access, eCommerce Style

•  Self-service and “zero touch.” –  Scalable automatic rental of resource intensive goods

•  Transactional and asynchronous –  Interaction with the site is transactional –  Delivery is asynchronous

•  Site integrity and site availability are critical –  Individual transactions can fail but the site cannot

•  Customer requests must be isolated –  Service venue must manage competing needs

•  Scale out for request volume, scale up for request weight


Open Source Cloud Platform

•  Idea: Develop an open-source, freely available cloud platform for commodity hardware and software environments

–  Stimulate interest and build community knowledge – Quickly identify useful innovations –  Act to dampen the “hype”

•  First-principles cloud implementation –  Not a refactorization of previously developed technology

•  Build from mature open source technologies –  J2EE, MySQL, Web Services are high quality and scalable as

open source

Service Delivery User Requests


Eucalyptus Generations

•  Eucalyptus 1.X (June 08 through Sep. 10) –  University code

•  Eucalyptus 2.X (June 10 through Feb. 12) –  Commercial focus, early production

•  Eucalyptus 3.X (present - ) –  Production operational improvements –  Full commercial feature set (almost)

•  Few, if any features deprecated –  BitTorrent?


New Eucalyptus 3.0 Features •  High-availability (HA) of the Eucalyptus Service

–  Hot fail-over and repair for all components except NC

•  AWS Identity and Access Management (IAM) API plus extensions for private clouds

– Quotas and metering

•  Eucalyptus Block Storage improvements –  AWS Volume-backed instance API (persistent instances)

“bootable” –  NetApp and JBOD support added to existing Dell Equallogic

•  Full support for Windows images –  Seven different versions, AWS compatible authentication,

sysprep, ephemeral disk

•  Accounting/Usage reporting –  Charge-back interface linked to quotas


Eucalyptus 3.0 Platform Improvements •  Revamped image caching in the NC

–  Faster instance starts using copy-on-write

•  Refactored VMWare broker –  Faster and more robust image preparation, support for vSphere 4.X,

improved scale, more extensive deployment topologies

•  Extended Linux distro support –  RHEL 5 and RHEL 6, packages for Canonical LTS (Ubuntu 10.04)

•  Substantial improvement in automated QA –  Full QA sequence is 5 days (features + distros + hypervisors +

deployment topologies + networking modes)

•  Re-designed administrative webUI •  Improved command-line admin tools •  Re-designed packaging, upgrade and dependency management •  Re-designed installation mechanism (package repositories)


Eucalyptus in The Wild

•  Eucalyptus 2.0 Deployments – Games, mobile infrastructure, media, telecom

•  Tons of feedback –  Not all of it angry

•  Top 3 –  Platform HA -> VM connectivity and request service – Quotas, accounting, reporting – Windows (fast image creation and start)


High Availability

•  Eliminate single point of failure –  Host failure –  Network connectivity failure (including network partitions)

•  Tolerate as many multiple failure cases as possible •  Avoid data loss at all costs

–  Fail stop is better than data loss

•  Availability of the services that Eucalyptus offers –  Eucalyptus requests –  VM connectivity and storage –  Not VM HA -> application level

Interesting Brain Wrinkles

•  Cloud and Walrus have externally visible URLs –  DNS remapping service is built into the CLC

•  What happens if the master loses connectivity with the user?

–  Back-up may have an alternative path to user •  Arbitrator service

•  Multi-failure can cause split brain – Master fails over, new master fails before original back,

original then brought up => fail stop


IAM, Quotas, and Reporting

•  IAM is AWS “Identity and Access Management” –  Accounts and users, and groups of users –  JSON based policies defines calls that users and groups can

execute –  Also possible to attach policies to resources S3 (buckets for

now) –  Linked to LDAP and AD

•  Eucalyptus extends the IAM predicates with inequalities –  Implements quotas as tests against IAM policies

•  Resource usage information exportable in a variety of formats and through GUI


For Example

eucalyptus support sales dev

EC2 image permission

S3 bucket ACL

quota

quota

{ "Version":"2012-‐02-‐12", "Statement":[{ "Sid":"2", "Effect":“Limit", "Action":"ec2:RunInstances", "Resource":"*", "Condition":{ "NumericLessThanEquals":{ "ec2:quota-‐vminstancenumber": "256" } } }] }


Windows

•  Windows images are big – One customer wants 200 GB images –  Ephemeral within the C: drive

•  Need a way to use CoW to improve Windows launch time


The Blob Store

•  Blobs are (sparse) files on the file system –  remember to use ‘ls –s’ to see disk space allocated –  files are mounted on loopback when in use –  future implementation could use LVM volumes instead of files

•  Mapping and copy-on-write snapshots are implemented using Linux kernel’s device-mapper (same as LVM snapshots)

–  once snapshotted or mapped, file access method cannot be used

–  i.e., backing file on disk no longer has the bits you want


What’s Next? •  Eucalyptus 3.1 (Q2)

–  Refactoring for packaged plug-ins –  VMWare 5 support –  AWS fidelity enhancements

•  Eucalyptus 3.2 (Q4) –  Feature release – More AWS fidelity enhancements –  ELB, Cloudwatch, Autoscaling

•  Eucalyptus 4 in 2013 –  Network refactorization – Multi-datacenter support

•  Eucalyptus 5 in 2014 – Multi-datacenter support


Just the beginning


Thanks!
