SCOPE Backups & Restores across public clouds (AWS & GCE) and private clouds (Openstack + VMWare)

VMWARE & OPENSTACK CO-OPETITION Co-operation 1. Openstack using VMWare 2. Complement features - VMWare (live migration, DRS etc) & OpenStack (Object Storage for backups) Competition 1. Customers see Openstack as an alternative to VMWare 2. Migrate VMWare environment to a neutral environment

CURRENT VMWARE + OPENSTACK INTEGRATION Grizzly 1. ESX Driver (no vMotion, DRS, HA) , Driver runs in 1 nova instance per ESXi host 2. VC Driver (vMotion, DRS, HA), Driver runs in 1 nova instance per ESXi cluster, abstracts cluster Havana 1. “Multi-cluster” management, 1 nova instance for multiple ESXi clusters 2. Block storage volumes (Cinder) can be stored as VMDKs as VMFS datastores (Snapshots go to vCenter datastore). 3. VOVA (VMWare Openstack Virtual Appliance) – packaged OpenStack vApp Icehouse roadmap 1. Cinder replication across different OpenStack installations 2. VMware Datastore Storage Backend (use image location reference instead of migrating the images) 3. VM diagnostics

VMWARE BACKUP & DISASTER RECOVERY - TODAY 1. Consolidate backup VMDK disks are snapshotted and mounted to backup proxy server and copies made to backup storage. 2. VMs as physical systems Backup agent runs inside the VM and backs up data to backup servers or attach iSCSI tape as media & copy 3. VMs as a file on ESXi Backup agent runs on the ESXi console & backups the VMDKs as a file to backup server.

RELIABILITY & HA ? Twitter blames two-hour failure on dual data-center crashes. Rawashdeh, VP, Infrastructure Operations Engineering at Twitter. called an "infrastructural double whammy.“ Earlier: • managed hosting services from NTT America • Amazon’s cloud computing services to store and deploy images, including profile pictures The flooded lobby at the Verizon site at 140 West Street during the height of the storm surge Monday night. (Photo:Verizon) Now: Twitter has setup datacenters to cater to its IT needs

WHAT DOES THIS IMPLY ? 1. Distributed environment (not all eggs in one basket) 2. Reliable Backup technology 3. Diverse clouds & infrastructure for backups

NEED FOR OBJECT STORE BACKUP Object Store [1] - Distributed data (3 sites) compared to RAID backups (3 copies + Tape backup) 1. Capacity: 60% more efficient 2. Cost : 80 – 90 % cost saved 3. Reliability : 100 Million times more reliable Swift:  Scalable  Durable  In house deployments [no-vendor lockin, cost effective, less latency] [1] Ref:

PROPOSED SOLUTION VMWare VCDriver + Object Store for backup 1. Backup vmdks (root, data & snapshots) on to Object Store (Swift/Amazon S3) 2. Restore vmdks to VMWare shared datastore

VMWARE VCDRIVER + OBJECT STORE FOR BACKUP Swift Store Glance Store Glance Images Swift Service Glance Service Cinder Volumes Nova VMs Nova Service Cinder Service Attach/Detach Vols Google storage upload_image/ fetch_image S3 Backup/restore images + volumes VCDriver VCenter ESXi Cluster ESXi Cluster Shared VMFS Datastore

VMWARE VCDRIVER + OBJECT STORE FOR BACKUP (CONTD.,) (root disk, data disk, snapshot disk) Restore Backup VCDriver Swift Service S3 Google Storage Distributed (multi-site), reliable & HA storage vCloudSync (Backup As A Service) Glance Store Shared VMFS Datastore

VCLOUDSYNC vCloudSync  Backup VMDK to AWS S3 & Google storage (Offline backups)  Restore VMDK back to VMWare  Google agent to migrate VMs between VMWare & GCE (Centos & Ubuntu) Roadmap  Snapshot backup  Integration with VCDriver/OpenStack  AWS agent to migrate VMs between VMWare & AWS (Ubuntu)

WHY VCLOUDSYNC ? + Agentless backups + Optmized for cloud backups and no local backups + Optmized Chunk size + Multi-part backups + Simultaneous backups + Deduplication + Compression (Ratio - 10:8.9) + ~ 20% better upload performance compared to manual uploads + Agnostic to virtualization or cloud technologies - Backup As A Service Engine + Reliability – meta data based backups
