Cloud Computing Standards


Cloud computing has grown considerably in a few years. This rapid growth, however, has led to the emergence of many incompatible achievements despite the efforts of standardization groups. Lack of standardization, particularly with regard to security or data protection, makes it difficult to compare offers.

However, the interoperability between offers and the portability of services becomes a very important aspect so that users can both maximize their return on investment by choosing the most suitable offers while avoiding being locked up in a single supplier.

Virtualization plays a vital role in the means of cloud computing. Hypervisors manage servers and associated resources to run multiple virtual machines that use different operating systems. Cloud computing platforms that use different types of hypervisors are therefore not interoperable. If you want to move a virtual machine from one platform to another, you have to recreate the same virtual machine to the standards of the new platform which can be complicated and time-consuming.

Here are some examples of standardization efforts that can emerge knowing that in a discipline that evolves very quickly, this standardization will take a long time to develop and deploy.

Open Virtual Machine Format (OVF)

Open Virtual Machine Format (OVF) at the end of 2007, Open Virtual Machine Format or OVF was proposed as a standard disk storage for virtual machine images for several virtualization platforms. Some industry players are collaborating on this initiative led by Distributed Management Task Force, Inc. (DMTF), such as Novell, Dell, HP, IBM, Microsoft, VMware, and XenSource (Citrix).

This new specification should help ensure portability, integrity, and automate the installation and configuration phases of virtual machines.

Open Grid Forum

The Open Grid Forum (OGF) is a community of users, developers, and vendors that develop the Open Cloud Computing Interface (OCCI). OCCI defines protocols and interfaces for various cloud systems management tasks including deployment, automatic sizing, and network management.

In fact, these interfaces, inspired by those that exist on systems like GoGrid or Amazon EC2 described later, will allow interacting in a unique way between the different platforms of the IaaS model.

Storage Networking Industry Association

The SNIA cloud data management interface standardizes data storage in important areas such as user interaction with data, quality of service and encryption, and how to transfer data from a data warehouse. Cloud to another.

These standards should be proposed soon to standardization bodies such as ANSI or ISO.
