IBM mainframe new architecture for private cloud

After several years of brewing and development, cloud computing is moving from theory to practice, "cloud computing is not a cloud" this issue has been very few people to discuss, the cloud is also from perceptual knowledge to the rational understanding, no longer follow the trend to hype a concept, arguing the definition of cloud computing, and focus more on how to get the cloud to the ground.

As we've seen, cloud computing has gradually come down from the altar and started to think seriously about how to serve the business. Cloud computing is gradually drawing a wonderful picture of people: cloud computing can allow users to pay according to the use, which can save a lot of upfront investment; system upgrades or new business online more calmly, no longer wait for the lengthy approval process; stripped of the specific hardware platform, not only the system resources to use more fully, more energy efficient System management and maintenance of the difficulty is greatly reduced, more able to fully release the energy of the system, making the system more flexible. The temptation of these dreams, so that enterprises involuntarily toward the cloud.

Depending on the nature of the service, cloud computing can be differentiated into public, private, and mixed clouds. What kind of cloud is more likely to reach the ground? Many industry experts have suggested that the public cloud in security, bandwidth, standards, etc. are difficult to achieve in the short term, so the private cloud is considered to be the first landing of the cloud.

and the vendor side also attaches great importance to the development of proprietary cloud products and technologies. As in the May 2010 EMC World Conference, the theme of the Conference was to move towards a private cloud; Microsoft also recently launched a proprietary cloud-specific server operating system; Cisco, EMC, and VMware have jointly launched second-generation Vblock products; Oracle's cloud strategy focuses on the importance of private cloud , VMware, Novell, CA, DataDirect and other manufacturers have also expressed the importance of private cloud. IBM as a total solution provider, with the "Blue cloud" strategy as the core, launched a series of servers, storage, network, including the whole solution.

The private cloud, which provides operational services to an enterprise within the enterprise's firewall, is more secure in terms of security, compliance, and quality of service than the public cloud, making it easier to integrate existing applications and reduce operating costs.

Private Cloud Erection Considerations

So, how does an enterprise build a secure private cloud? A private cloud is not a castle in the sky and requires a "cornerstone" that can carry it. And we think that the enterprise data center is to support the private cloud operation of the "cornerstone". Of course, enterprise data centers have a series of tests to meet the conditions of private cloud: The reliability of data center, the compatibility/interoperability of its internal devices and applications, manageability, and so on.

to support the environment in which the private cloud is running, can the enterprise's data center meet these requirements today? We know that most of the architectures offered by the major manufacturers are still each other is a confrontation rather than open fusion, so that the enterprise's hardware and software choice of space is very limited, once the choice also means that must be bound, and who if you want to be in the room or data center deployed heterogeneous systems, then compatible, interoperability, management, A series of challenges in terms of security will swarm.

So, what factors do users need to focus on in private cloud driving? What errors do users have to avoid?

One, standardization. For a private cloud, it does not mean a long, closed environment. The future of the enterprise will inevitably move towards a mixture of private and public clouds. Therefore, the standardization of work is the first thing enterprises need to consider. For example, in server consolidation, UNIX servers are relatively more compliant with private cloud security and reliability requirements. But it brings closure to the user. Especially in the future, when the enterprise gradually moves towards the mixed cloud stage, the process, the application, the business interface inevitably needs to make the change.

Two, automation. Private cloud computing environments are not as common as the public cloud, where anyone can deploy their own virtual machines and applications, which, if private clouds do, will inevitably cause confusion to the business. Therefore, an automated process is particularly rare. For example, a user of an enterprise needs to apply for the resources they want, how the private cloud implements these processes quickly and automatically, and so on. The prerequisite for automation is the standardization process that requires efficiency and consistency. Automation is also one of the keys to determining the success of private clouds, and without good automated processes, private clouds will be inefficient.

Three, highly virtualized, highly resource-sharing. Private cloud Another key factor is the high level of virtualization and the high level of resource sharing. Virtualization is not just a reflection of server virtualization, network virtualization, storage virtualization, desktop virtualization. Only highly virtualized can bring a high level of resource sharing.

Four, large flexible space, strong scalability. Cloud computing is actually helping users achieve the need to use IT resources flexibly and efficiently. For the cloud computing platform, it must have a very large elastic space and good scalability.

In addition, security, manageability is also an indispensable factor, in a highly resource-sharing environment, how to ensure security and manageability, the importance of this issue is self-evident.

users are not flat on the private cloud, and standardization, automation, virtualization, resiliency, security, manageability, etc. are key elements in the future of private cloud construction. Without a standardized, open, virtualized, resilient architecture environment, even if it can now meet the needs of the business, but as the public cloud revolution continues to advance, enterprises to the mixed cloud, the time will face a dilemma.
