Why Hybrid Cloud Public Cloud Private Cloud

Easy scalabilityCost effectiveness

Increased reliability

Improved securityGreater control over the

Cloud Bursting

Less critical data Test & Dev workloads

Archival / backup data Sensitive / critical dataProduction workloads

Key problems in Hybrid cloud

● Security● Account management and billing● Network● Disaster Recovery● Migration

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

Now: Twitter has setup datacenters to cater to its IT needs

What does this imply?

● Distributed environment (not all eggs in one basket) ● Reliable Backup technology ● Diverse clouds & infrastructure for backups

Disaster Recovery● How

● Available Options● Store backup in local server● Store backup in cloud

● Local Server● Pros

● Security ● Cons

● High cost● Cannot replicate in different geographical locations● Small Org’s cannot afford● Scalability

Disaster Recovery on Cloud● Cloud can act as a secondary DR site● Pay as you go● Unlimited secondary storage● Distributed backup - High availability

VMware Backup & Disaster Recovery- Today● Consolidate backup :

● VMDK disks are snapshotted and mounted to backup proxy server and copies made to backup storage.

● VMs as physical systems :● Backup agent runs inside the VM and backs up data to

backup servers or attach iSCSI tape as media & copy ● VMs as a file on ESXi :

● Backup agent runs on the ESXi console & backups the VMDKs as a file to backup server.

Need for Object Store Backup :● Object Store [1] - Distributed data (3 sites) compared to RAID

backups (3 copies + Tape backup) ● Capacity: 60% more efficient ● Cost : 80 – 90 % cost saved ● Reliability : 100 Million times more reliable

Swift: ● Scalable ● Durable ● In house deployments [no-vendor lockin, cost effective, less

latency]

CloudOps - backup● Cloud based backup● Agentless backup● Optimised chunk size● multi-part backup● Simultaneous backup● De-duplication● Compression ratio 10:8.9● ~20% better upload performance compared to manual

uploads● BaaS - Cloud agnostic

Disaster Recovery● DEMO

Portability & Composability so far…

Migration● Why

● Move Workloads from private to public and vice versa● Moving to different cloud providers● Dockerize

Migration● Demo
