EucaDay NYC 2012: Tim Cramer "Eucalyptus 3 and Beyond!" Presentation Transcript

  • 1. Eucalyptus 3 and beyond! Tim Cramer VP, Engineering April 25, 2012© 2012 Eucalyptus Systems, Inc.
  • 2. Eucalyptus Multi-tiered Service Architecture Service User Requests Delivery User Transactions Inventory Inventory Inventory and and and Scheduling Scheduling SchedulingActualization Actualization Actualization Actualization Actualization © 2012 Eucalyptus Systems, Inc. 2
  • 3. Eucalyptus Components • Cloud Controller (CLC) – User request processing (except for Walrus), Credentials management, VM (instance) state management • Walrus (S3) – S3 user request processing, Append-only, Put/Get object storage • Cluster Controller (CC) – VM inventory, Network provisioning/security group implementation • Storage Controller (SC) – Block level, network attached storage (SAN and Linux) • Node Controller (NC) – Hypervisor interface and control, VM launch/decommissioning • VMWare Broker – Gateway between CC and ESX and/or vSphere for VMWare © 2012 Eucalyptus Systems, Inc.3
  • 4. Component Architecture Service User Requests Delivery CLC Walrus CC SC CC SC CC SC NC/VMWareB NC/VMWareB NC/VMWareB NC/VMWareBNC/VMWareB © 2012 Eucalyptus Systems, Inc. 4
  • 5. Eucalyptus Generations • Eucalyptus 1.X (June 08 through Sep. 10) – University code • Eucalyptus 2.X (June 10 through Feb. 11) – Commercial focus, early production • Eucalyptus 3.X (present - ) – Production operational improvements – Full commercial feature set (almost) • Few, if any features deprecated – BitTorrent? © 2012 Eucalyptus Systems, Inc.5
  • 6. 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 (EBS) 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, ephemeral disk • Accounting/Usage reporting © 2012 Eucalyptus Systems, Inc.6
  • 7. 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)• Re-designed administrative webUI• Improved command-line admin tools• Re-designed packaging, upgrade and dependency management• Re-designed installation mechanism (package repositories) © 2012 Eucalyptus Systems, Inc. 7
  • 8. 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) © 2012 Eucalyptus Systems, Inc.8
  • 9. 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 © 2012 Eucalyptus Systems, Inc.9
  • 10. HA Web Service Architecture • All Eucalyptus components are implemented as Web Services – CLC, Walrus, SC, VMWare Broker– Java – CC and NC - C • CC and NC are each implemented in separate Axis2c service container • CLC, Walrus, SC, and VMWare Broker share a web service stack and JVM when co-located © 2012 Eucalyptus Systems, Inc.10

  • 14. Group Membership and Heartbeat • HA is from the perspective of the “master” CLC • Jgroups determines which machines are “up” • Heartbeat determines which services are available within the “up” group • Back-up CLC monitors the “up” group to determine if it contains a master – If not, it becomes the master • Master and Back-up DBs kept synced – Resync when failed CLC is restored © 2012 Eucalyptus Systems, Inc.14
  • 15. 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) • 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 © 2012 Eucalyptus Systems, Inc.15
  • 16. For Example eucalyptus dev support sales { "Version":"2012-02-12", "Statement":[{ "Sid":"2", quota "Effect":“Limit", EC2 image permission "Action":"ec2:RunInstances", "Resource":"*", "Condition":{ S3 bucket ACL "NumericLessThanEquals":{ "ec2:quota-vminstancenumber": quota "256" } } }] } © 2012 Eucalyptus Systems, Inc.16

  • 18. Quality • Continuous integration and testing during development • Automated Quality Test Harness – PXE booting clouds • GUI Testing • Networking modes + features tests + distros + hypervisors + deployment topologies – Approximately 400 combinations • HA Testing – Graceful failover, Machine reboot, Network loss • Scalability testing • Publically accessible Beta Clouds • Security Audits • Coverity / Memory profiling © 2012 Eucalyptus Systems, Inc.18
  • 19. Eucalyptus 3.1 • Open Source of 3.0 • New platform support – VMWare 5, Ubuntu 12.04 (Precise), CentOS 6 • Continued platform support – RHEL 5/6, CentOS 5, Ubuntu 10.04 (Lucid), VMWare 4.1 • New method of working – In the open • FastStart • EuStore • Documentation improvements – PDF, HTML, Open sourced, ease of input – Best Practice guides, Getting Started Guide © 2012 Eucalyptus Systems, Inc.19
  • 20. Eucalyptus 3.1 – Repo Structure © 2012 Eucalyptus Systems, Inc.20
  • 21. What does the future hold…. • Eucalyptus 3.2 (Q4) – Feature release – Possibilities • ELB, Cloudwatch, Autoscaling, Instance Tags, EMC SAN, Management Console, Ease of use improvements • Eucalyptus 4 in 2013 and Eucalyptus 5 in 2014 – Application features -> services and API – Operational features -> ease of use, maintenance, performance • Please help! – tell us what Eucalyptus needs and when it needs it © 2012 Eucalyptus Systems, Inc.21
