Enterprises may wish to change their Cloud Hosting provider for many reasons that may include unexpected costs, frequent outages and insufficient support. However, during the change, the portability of data from one provider to another can range anywhere from difficult to unworkable. Read on to learn more about the curious case of data portability in the Cloud.
A research by IDC has revealed that more than 52% of organizations wanted to move their Cloud data from their current service provider to another provider or to their in-house infrastructure. While in the traditional setup, there is the luxury of moving resources without extensive planning, the scenario is pretty different when it comes to the Cloud environment. Moving data from one Cloud service provider to another can be disruptive to the existing operations when there is business-critical data involved.
What are the major portability issues in Cloud-to-Cloud migration?
1. The slow transfer rate of TCP/IP networks that is used in the Cloud takes almost 6 days to move one terabyte of data. This number stems from the universal Cloud transfer rate of 20 megabits per second.
2. Network issues that revolve around the use of DNS (Domain Name Services) and internal configurations.
3. Transfer of data must be marked by the best practices in data governance and data security in order to establish maximum control over it at any point in time. Ownership of data must be established appropriately.
4. When moving data from internal infrastructure to the Cloud environment, the challenges are worse as moving VM images is much easier from a virtualized environment to another. Reconfiguring of network settings in this case is much more complex.
Assess the strength of the Cloud service provider in enabling Cloud portability
The following portability recommendations can facilitate easier data portability.
1. Block-level deduplication, virtual cloning and compression can reduce Cloud to Cloud data transfer time span by almost 50%.
2. Third-party ID and access management functionalities can be used to authorize Cloud services. When dealing with multiple Cloud vendors, the security measures of one Cloud Hosting provider must be compliant while leveraging the services of another.
3. In-house applications that are based on SOA design principles can use standard APIs for better interoperability with the remote Cloud.
By using the right techniques and tools, it is no longer necessary to allow data to reside in siloed Cloud environments.
