Cloud computing standards and application migration

Summary: Open cloud computing standards are considered to be the ultimate solution to the problem of application migration and cloud computing interoperability. We treat cloud computing standards as a collection of criteria derived from standards such as OVF (developing virtualized formats) that provide you with a common language for describing the metadata and configuration parameters of a virtual machine. In the previous layer is a useful environment (the connection between virtual machines) described. This will provide you with information about the environment of the virtual machine, the function and scale of the virtual machine operation environment.

Because of the continuing innovation in cloud computing, we will not see the introduction of cloud computing standards this year or next. Vendors like VMware will be happy to see this and say: "I can provide you with the entire black box solution, buy our products, you can build a cloud and provide it to your customers." "Cloud-computing providers don't like the idea because they want to differentiate their services. If the cloud finally becomes a commodity, they do not want to go the way of standardization. If 11545.html "> We have standards, it is almost certain that cloud computing providers are difficult to provide a unique product based on standards."

Cloudswitch's CTO, John Considine, points out that for cloud computing providers, standards are an urgent requirement for customers and http://www.aliyun.com/zixun/aggregation/14341.html " > provides guidelines for implementing cloud computing. In the case of VMware's Vcloud API (which was submitted to DMTF to approve a development standard as a cloud-computing API), the configuration and access of cloud computing environments involved resource definitions and virtual machine directories. These "Tasks" have a direct impact on the implementation of their cloud computing projects by vendors.

What are some tips on cloud computing application architecture design? One suggestion is not to design your application and its supporting stack components based on your operating system and infrastructure. The more you do this, the worse it will be in terms of interoperability and application portability. If you use a mature fourth-generation language or an interpretive system to write an application, you have a better chance of interoperability.

The problem you may encounter is the inability to get the performance and functionality you need. In addition, you may want to avoid using some of the performance and functionality benefits that are available from the management utility or the specified operating system. You may also need to implement the class operations and diversity functions of your application to ensure its portability across the cloud.

What kind of existing applications are best suited to run in the cloud? The more common and high-level applications are, the more likely they are to migrate across the cloud. One of the weakest areas of cloud computing is the need for full control of the operating system. If you are running an older Linux or Windows operating system, you may be in trouble; most public clouds do not support these older versions of the operating system.

Migrating applications across the cloud is not easy. However, when the open standards of cloud computing and tools such as Cloudswitch and Racemi are present, they can alleviate the problem to some extent and further the substantive implementation of the Hybrid cloud.
