VMworld Call for Paper – Public Voting is Open

Yesterday VMware has open up the public voting catalog for VMworld 2013 papers and I am really excited to see some of the super rich technical paper.

Well, I have submitted my bit there as well and looking forward to see how are you going to like this paper.

  • Did you know that BC/DR is one of the crucial aspect of success story of Public Cloud?
  • Do you want to know how to Design a effective BC/DR solution for your Public/Hybrid Cloud?
  • Do you know how effective a BaaS (Backup as a Service) can be in your public cloud?

If any of your answer is “NO” then you should vote for this session to see how we at VMware R&D is working for this. Listen to us who has designed, architected, implemented and tested the BaaS solution.

Title: Architecting Backup as a Service for vCloud Hybrid Service

Session Number: 4985

Abstract: The goal of this design paper is to provide all the necessary information to assist the service providers with architecting a Backup as a Service solution in a VMware based Hybrid Cloud.

In a Hybrid Cloud solution, backup deals with more scalability rather than the vApps in a vCloud. vCloud workload backup solution has to manage vApps in the cloud plus the deleted vApps, orphaned vApps in vCloud etc. So to allow customers to move to the Cloud scale, we need to provide automated application of selectable backup policies which in turn should be standardized as well.
Service Provider should assign customers vApps depend on the SLA level too, for an example, attached the vApps to Gold, Silver and Bronze backup workflow pipeline. Also considering this backup solution for cloud workload, it should support Public, Hybrid and Private Clouds because customers buy cloud for flexibility and agility. Also backup must be fully cloud aware and flexible.

A Service Provider should consider resource metering too while architecting the backup solution, such as, storage, IOPs, network, bandwidth etc. This allows a provider of the service to enforce backup resource allocation choices too. A customer should be able to choose from PAYG, Reservation or allocation model.

So in a nutshell what this vCloud backup does for you is, though it costs you something now, however if there is a catastrophic failure happens then it pays you back more than the premium you paid to the service provider.

I have submitted another panel discussion session which includes a demo as well of our tool (Bezoar) which does self discovery and self healing of our VMware vCloud Hybrid Service. You will see it in action if it gets selected.

Title: Bezoar: Self-healing vCloud Hybrid Services

Session Number: 5116

Abstract: In the era of public, private and hybrid clouds, it is a challenge to minimize the downtime. Our datacenters are no longer a collection of just physical resources connected together but a complex and intricate combination of virtual and physical infrastructure working in perfect harmony with multiple levels of abstraction. As beautiful as this may sound, this whole ecosystem hangs by a very thin thread where a small error threatens to bring down the complete cloud. Finding and fixing problems fast is the key.

Bezoar can automatically understand your cloud architecture, monitor its components, identify root cause, perform impact analysis and heal your cloud. It does not stop there; it is a self-learning system with intelligence to prevent the same problem from recurring in future.

To achieve this, our auto discovery algorithm will probe and learn relationships between various physical and virtual components of the cloud and map the dependencies between them. This is how Bezoar learns about your cloud. We store these complex relationships in our CMDB, to be used later for impact analysis and help cloud admins to visualize their complete infrastructure.

Our system will continuously monitor your cloud and its services to report health per tenant. As soon as one of the components or its service goes down, Bezoar alerts you and swings into action to rectify the problem. If it doesn’t know how to fix the problem it will ask for a solution that will be recorded into its RCA DB for self healing in future.
