You might think that using http://www.aliyun.com/zixun/aggregation/13422.html "> Cloud computing technology is a bad thing in the absence of a standard for managing cloud computing services." If you think so, you are wrong.
For any new technology, you can usually speak two things without causing any trouble: the standards are not mature enough and the management is inadequate. But the truth is that most businesses should not take the lack of cloud computing standards as an obstacle. The lack of standards for managing cloud computing services is a good thing because these standards may come later, and the best thing is that they don't happen at all.
Each cloud vendor has its own management tool designed to provide users with a way to handle a subset of the application platforms. In fact, this part of the application platform (including application software, operating system, middleware and hardware) is the real service of the cloud provider. For companies planning to adopt a single cloud vendor, the management system provided by the suppliers is what they need, and it doesn't matter whether the system meets the standards. Companies should be cautious about using multiple cloud services, but far from abandoning the use of the cloud.
SaaS Management vs. PAAs Management
SaaS, the enterprise does not need to provide any technology to the cloud, and the cloud vendor has full control and management of the application. The benefit is that SaaS management involves only managing the application, and the infrastructure is not visible to users, which means that SaaS management focuses only on controlling the use of the application and, of course, on the way data is stored and backed up.
The above capabilities provided by cloud vendors are related to specific applications in the cloud, so cloud management standards may not have much impact on SaaS. If you are a SaaS user, with no standard support, you can manage your application by self-regulation to minimize the burden of management.
For PAAs, the cloud has servers, storage, operating systems, and application middleware tools such as database management systems. Enterprises need to provide application software and some additional middleware components. It also helps with application management, which means that the way business management PAAs is applied is the same as managing data center applications, except that the installation is not onsite but remote.
A data center that uses PAAs mode can be called a cloud. In common PAAs models such as Microsoft Azure, the management portal manages the entire PAAs environment.
Organizations that use two different PAAs clouds may find the management process difficult to reconcile for the following two reasons:
1. Like application management, platform management depends primarily on the components of the platform and how the components are organized. Because PAAs products are different in their own right, each PAAs vendor's management system is likely to be different.
2. For businesses that use two or more different PAAs vendors, it is recommended to use two or more distinct server platforms in the datacenter: Windows and Linux, for example. People with these experiences know that it is difficult to coordinate management and support processes across multiple platforms, and that coordination becomes more difficult when you have to use the cloud management interface rather than the internal management options you can use. But like SaaS, PAAs can hardly expect cloud management standards because cloud platform components are likely to vary so much that it is impossible to manage them in a coordinated way.
How does the IaaS management standard stand out?
Cloud management standards are mostly related to IaaS because, in addition to the hardware itself, the IAAS model almost allows IT managers to make any choice. Migrating your favorite management tools into the cloud and using them in the cloud is a great opportunity. You don't need to change your application and platform management practices, but you need to manage how cloud vendors Allocate server resources, storage, caching, and other tools.
Because the enterprise is likely to have multiple IaaS vendors compared to PAAs and SaaS, the IaaS standards are critical, and although IaaS is complete and compliant and may benefit from cloud management standards, it is not possible to meet all of the requirements for IAAS standards.
The first issue is the diversity of cloud management standards, which has been the subject of numerous cloud standards groups. At the popular Cloud Standards Group summary site, 13 groups are listed, with at least half of them interested in a particular type of cloud management standard. They are committed to cloud standards, but there are no uniform standards available at the moment.
The second problem is that leading cloud providers rarely support these standards. In the case of Amazon, it is impossible to follow the work that these groups are embarking on.
How to align as much as possible with future cloud management standards? That is to use as many administrative toolset as possible within the cloud architecture. It is also important to expect most vendors to follow Amazon's cloud management approach as much as possible, and if there is a unified cloud management standard in the future, it is likely to remain compatible with Amazon's cloud management approach.
Finally, even when there are different management options within the cloud service, you should rely on advanced management tools such as HP's OpenView or IBM's Tivoli reconciliation-related management practices. While this may not be easy, cloud management may not be a problem compared to what you think.
