vCloud Availability – Real World Architecture Details on VMware’s Latest Replication Tool

Hard Truths about Replication…

• “Replication recovery in most cases are crash consistent”

• If you recover an application built on top of multiple servers, you are recovering and praying

• In the past replication mostly supported DR. Availability is a post 2004 phenomenon

• Availability has needs above and beyond basic replication

• Replication copies are used to source backups, stand by copies for test, reporting assets

• Virtualization and cloud based technologies enabled reduction in needs of identical hardware and allowed smaller compute footprint and on demand compute consumption during fail over

• 95% of recovery and fail over is to demonstrate you can when that one actual recovery occurs.

• Application resiliency: is what most people look for recovery solutions for

– In the cloud age, this is table stakes, big boys play with contractual resiliency

• Contractual resiliency: portability of an application across service providers with ability to demonstrate service resiliency is now required by law.

Evolution of Replication Based Technologies

• Change Capture and Copy on Write (file system and volume level) technologies have enabled

– Snapshots, Replication, Backup

• At the core of it, a driver grabs the file block or volume block being changed, either write it in place, copy out old data, or grab the new copy, replicate it else where, apply to a change log

– Create point in time volume images based on snapshots

– Allow all changes to be logged so that various continuous snapshots can be made available

– Over a period of time consumes large amount of data

– Drove consolidation to known recovery intervals so that the replicas became based on copy on write

– Crash consistent point in times also mean lesser data on the replica

– Integrate with application to create consistent images at various book marks

– Consolidate the data @ definite intervals and also create full images based on performance needs (RTO)

• Seeding replicas simplify initial kick off

Applications of Replication Based Technologies

• DR

• Snapshot of replicas (point in time recovery)

– Good for creating backups

– Reporting engine data feed

– Test server data feed

• Copy on write images on the replica

– Ability to mount snapshot of the replica while replication is continuing

– Verify recovery data consistency

– Great for testing use cases and demonstrating compliance

• Holy grail – High availability – on demand or upon automatic monitoring, create a writable snapshot of the replica, mount/boot, route traffic to newly mounted infrastructure, test, and promote the replica or destroy

Truth about DR & HA

• Replication based recovery/HA actions at large

– <1% are actually about recovering from a natural disaster

– <5% are to recover from a user or application error

– >95% are about testing & demonstrating conformance to compliance controls

• By default systems are crash consistent at DR image and or HA image.

• It’s the application!

– At times, applications span multiple VMs

– Consistent bookmarks/checkpoints/rewind marks are key in recovery

– Should be created across the constituent nodes as prescribed by the application.

The Many Sides of Replication – Key Points You Need to Know

Then

• ‘Must have’s for a replication solution in the old days

– Identical hardware and data center configuration

– Special networking gear

– What’s my encryption?, Special hardware

– Fidelity

– Live systems on both ends

– Application resiliency

– File system based

– Recovery

– Speed

– Rewind

– As you may remember

• Doubletake, XOsoft, Neverfail, Inmage, Sunguard….

Now

• Must haves for the 2017

– Simplified deployment

– No special hardware or VPN

– ‘Test while production is protected’

– Born in the virtual world – No CPU/RAM/Just Disk

– Contractual resiliency

– Replica VMs are mostly disk images spun up on demand

• No active consumption of CPU and RAM

– Orchestrated for consistency

• Across Virtual machines

• Application aware

– Secure & Integrated with identity providers

– Recovery testing to demonstrate control compliance

– DR testing as a service

Ceridian’s Data Protection and Availability Journey

• Explored multiple different DR solution over years

– Colo based DR program - Backup to tape – recovery from tapes

– Disk based backup – data availability at both primary and DR data centers

– Array based replication

– OS agent based replication

– Application based replication with SQL Always-On availability sets

• Now

– Hypervisor level replication between site to site

• Future:

– vCloud Availability and/or replication to the cloud

Why vCloud Availability?

• Born in the virtual Era – Just powered off VMs on the other side

• Integrated into vCenter/vSphere

• Application aware by integration with VRO– works across multiple VMs

• Built in testing

• Cost effectiveness

• Data Center and regionally deployed applications work identically

– NO VPNs – natively encrypted data replication

• Recovery system definition is pre-built

Considerations Before You Choose vCloud Availability

• Does vCloud Availability make sense for you?

• Checklist for client readiness

• application constructs (vAPP) portability – are you ready ?

• Do you understand your needs of Recovery point / recovery time objectives?

• Sizing guide

• Your data seeding strategy

• Needs for your recovery testing

• Latency ? Not the same as the pipe ?

• Day 2 Questions

• Provisioning failed-over instances mapped to your security domain

• Test on cadence(demo compliance)

• Seamless connectivity post failover

• Maintenance

– ESXi

– Storage

– VCD

• Scalability and performance guidelines
