One of the pain points that customers have is being tied to a vendor and as a result not able to experience some of the better tecnologies or features in the competitors products. This article provides a way out of Vendor lock-in and allows the customer to have a level playing feild and chose the vendor based on metrics rather than end up being tied to a vendor.

Systems and methods for Policy based Dynamic Migration of Virtual machines across Clouds

More often than not, we see customers getting stuck to one vendor once the vendor is finalized for the Cloud services. This is a classical example of "Moment of Inertia" i.e Objects continue to be in the same state unless a force is exerted upon them.

This situation though may be nice to have as it requires less change, would result in wasteful expenditure for the organization. A more proactive lookout into the Cloud market across various vendors would give the users a better bargain for their price on the various cloud features and ROI. The article aims to provide methods to help users know the comparative costs of various cloud vendors dynamically, while the cloud services are being used by the customers and thereby help them make a decision to migrate to cheaper service with similar SLAs. This method when implemented would enable users and SMBs to increase ROI dynamically as and when the services are being used by the customers. As of now this kind of service is not implemented by any of the Cloud Brokerages. In a Cloud Brokerage environment consists of 3 basic components. 1. Cloud Vendor 2. Cloud Broker 3. Cloud Customer.

The Cloud Broker provides services to the Customer from the Cloud Vendors. To provide access to various services to the customers, the Broker gets the details of various services and SLAs and prices form the Vendors. There are features on the Cloud Broker, which allows the customer to compare various features and prices for the SLA of the services from the Cloud vendors.

Once a vendor is selected based on various parameters like the SLA for the services and their prices, the Cloud Broker procures the services from the vendor on behalf of the customer and provides it to the Cloud customer.

When users have access to multiple Cloud Services from various vendors, it becomes a challenge to keep a tab on the costs and performance SLAs of the Vendors and the customer continues to use the service with which the customer is subscribed to.


- The costs of the services and performance SLAs are very dynamic in nature and keeps changing as per the demand from the market and infrastructure performance and various policies and regulations by governments and service providers.

- Users need access to the services at a competitive price. - Fees for switching vendors, due to price diff...
