It is been a while since i last wrote something in my blog, was just little busy helping customer through their journey towards cloud computing.
What everybody finds interesting including myself is the way cloud computing allow customers to automate their IT services provisioning. with VMware, you also control the QoS of these provisioned services based on the requirement.
Being in cloud computing doesn’t only means infrastructure. it is about infrastructure, applications and end users and how these cloud services are provisioned and implemented in these era’s of the cloud.
With VMware providing cloud computing for all of these cloud services weather it was in the private or the public cloud through the service providers. people needs to understand how these cloud services are actually being provisioned backend.
vCenter is been always the heart of the VMware virtualization management. other products are always integrated with vCenter server weather it was VMware products or third parties where they provide the customers the ability to provision their service through this management platform weather it was Storage, VoIP …. etc. The thanks all goes to vCenter API’s that has made this possible and allowed these vendors to do so very easily.
Customers have founds these features interesting and made vCenter the sole of their whole infrastructure management. but what customers are always confused about is why do they need to make vCenter highly available specially when it is deployed in the virtualized environment and can benefit from VMware HA.
Not to make this post long, customers need to know why vCenter availability is a major need in their transition to the cloud environment. keeping in mind that existing services will not be disrupted with vCenter being down immediately where the customers can run their environment without vCenter for a period for 2 weeks, but without the main features like vMotion and DRS.
without vCenter being available, VMware view and VMware vCloud Director will have the following effects.
1- VMware View: Existing desktops will not be effected but no new desktops can be provisioned because the provisioning process is done by the integration with vCenter API.
2- VMware vCloud Director: Existing infrastructure services(vApps) will not be effected but new vApps can’t be provisioned since it is depending on the deplyment through vCenter API’s.
so for customers to be able to make their cloud services always available. vCenter Availability should be a major concern for them so that the services can’t be disrupted.
With vCenter Heartbeat, weather your vCenter was in physical or virtual environment. it will will always be protected. and to save infrastructure if your vCenter environment was in physical environment you can place heartbeat in the virtual environment, you have no problem in the way you want to deploy it.
More about vCenter Heartbeat is available in the following link
Happy Available vCenter.
