Hybrid Cloud has arrived, business users are you ready?

Cloud computing has developed rapidly over the years, with private clouds in the past few years, and the public cloud has started to fire in the last two years. In this case, the hybrid cloud is also being put on the agenda. So what is a hybrid cloud? As the name implies, hybrid cloud is the combination of public and private clouds in the target architecture. For security and policy control reasons, not all enterprise information can be placed on the public cloud, so that most enterprises that have applied cloud computing will use hybrid cloud mode.

?

The hybrid cloud has three notable features: 1, More perfect. The security of a private cloud is beyond the public cloud, but the computing resources of the public cloud are not available to the private cloud. In the case of this spear and shield, the hybrid cloud perfectly solves this problem by taking advantage of the security of the private cloud, keeping the important internal data in the local data center, and using the computing resources of the public cloud to get the job done faster and more efficiently than a private or public cloud. 2, expandable. Hybrid clouds break through the hardware limitations of a private cloud, leveraging the scalability of public clouds to get higher computing power at any time. By moving non-confidential features to public cloud areas, businesses can reduce the pressure and demand for on-premises private clouds. 3, more savings. Hybrid cloud can effectively reduce costs. It can use both public and private clouds, and businesses can put applications and data on the most appropriate platform for the best combination of benefits. Hybrid cloud implementation in the enterprise, can reduce costs and flexible expansion of resources, but also the perfect security and elasticity.

For businesses, private and public clouds are not two separate individuals, and more often they need to work together in a coordinated effort. For example, running core and critical business in a private cloud, and fully leveraging high-end storage, databases, and quality resource services, while in peak demand and bursts, take full advantage of the public cloud to fulfill massive data processing needs without having to purchase additional hardware. This reasonable balance and dispatching resources is also the key to realize the maximization of enterprises ' interests. Because public clouds are billed for the resources you use, the public cloud becomes a very inexpensive way to address the peak of business demand.

Data is an important asset for the enterprise, and disaster recovery is necessary and important. What about the disaster preparedness of the private cloud within the enterprise? If you spend a lot of effort and resources to build a disaster preparedness platform, and wait for the disaster to take advantage of, it is undoubtedly a huge waste. If you use a hybrid cloud, you can provide a good basis for this particular arrival of resiliency requirements. This means that the enterprise private cloud can take the public cloud as a platform for disaster transfer and use it when needed. Or use the public cloud as a selective platform while choosing a different public cloud as a disaster-transfer platform.

So how do you build a hybrid cloud for your business?

1, reasonable assessment of the needs of enterprises

It sounds simple, but it's far from the truth, what do businesses need besides cloud services? For example, organizations should consider whether cloud computing can help save money and labor costs, as well as enterprise marketing, software and human resources software for business systems, or ordered applications. Another question to consider is how many applications and data stores can be migrated to cloud services, so as to release as much of the workload as it might otherwise have been. This, in turn, means that IT staff will have more time to study how to help the business sector innovate successfully.

2. Classification of enterprise data and business

A key step in the adoption of hybrid cloud solutions for enterprises is the need to scientifically consider what data information, the business to migrate to the cloud, and identify the sensitivity of these resources or their impact on the core business or enterprise IT strategy.

Classify your business units in the cloud according to their specific needs, and further identify what resources need to be kept within the enterprise? What can be put on the public cloud? What do we need to mix the public cloud with the private cloud?

The Enterprise hybrid cloud strategy should depend on which business or data should be in the private or public cloud. Before adopting hybrid cloud solutions, companies need to identify data and business classifications to make better use of the cloud for sustainable enterprise development.

3. Select the right cloud service provider

There are many cloud service providers on the market and focus on different areas. The enterprise needs to determine its own final requirements and then ensure that the chosen vendor is able to handle its own needs. Of course, you can also consider the use of a number of suppliers of services, make a full comparison, and finally find their favorite suitable suppliers.

For the traditional industry, especially the private cloud, the more consideration now is the convenience of IT management through automated operations, so that it becomes flexible and more secure, which is the current stage of the CIO, they consider the issue. At the same time, we also see that cloud computing has different stages of development, each enterprise because of its own information development and acceptance of new technology open degree of different, but also in different cloud computing stage forward. At present, the traditional industry relative to the Internet, is still relatively conservative. In particular, in terms of public cloud, it is prudent to consider security considerations. From a technical point of view, these two problems need to face and solve.

First, the combination of private and public clouds, unified management. Most of the traditional industry's it already has its own data center, can do private cloud transformation. However, with the public cloud resources, how to carry out unified management, how to flexible scheduling, how to be able to have their own control of network security, load offload capacity, which requires the private cloud and public cloud joint access and global control. A lot of new technologies are used here, such as SDN and NFV, the public cloud is complex, there are many independent users, traditional network architectures are difficult to implement, a tenant needs a separate architecture, requires SDN, and requires network security and quarantine control. There is also an important infrastructure overlay to address the limitations of network isolation/separation capabilities. For a limit of 4000 VLANs, a user ID similar to the 12-bit VLAN ID is introduced in overlay technology, which supports user identification above tens and inherits the concept of cloud computing "tenant" in overlay. Supporting cloud and virtualization building requirements with overlay virtualization enables large-scale multi-tenancy capabilities while enabling global controllability in the cloud. There are Servicechain is the service chain, why with the service chain, software defined after we need to navigate or string up the data flow, we need to pass through LB, through the IPs through the IPs, need to pass through the firewall through the firewall, All security technologies can be strung together in the data center via Servicechain. The landing of these technologies allows you to manage the public cloud like managing your own data center, just like managing your own private cloud.

Second, store the backup. Traditional architecture online storage, backup archiving, offsite disaster recovery, now needs to be replaced by public cloud, because the public cloud price is relatively cheap. But you will find that there are quite a few problems to be solved. For example, the network bandwidth is very limited, how to compress the data and the process of eliminating heavy transmission, the amount of data that needs to be transmitted is smaller overall, the faster the transmission, the shorter the time, of course, also save bandwidth costs. There is the security of data, such as the private cloud to the data security requirements are very high, the traditional industry has information security level protection, need to be out of the public cloud data are reviewed and approved, while ensuring data security. Then consider how to end-to-end encryption, even the public cloud can not see my data, public cloud operators can not access my data, as well as security isolation, permissions control and so on, need to be resolved in the backup storage hybrid cloud.

In the era of cloud computing and big data, VMware was the leader in virtualization and cloud computing, announcing one cloud vision to run and manage cloud-native or traditional applications through a software-defined platform across private and public cloud environments. That is, on top of the same cloud infrastructure, hosting different applications, supporting different devices, and delivering any traditional or cloud-based applications across a highly consistent application environment spanning both private and public clouds. A key part of this vision is the release of the VMware Integrated OpenStack product version, which can be used to run cloud workloads. This February, VMware released VMware VSphere 6, the latest version of the virtualization solution for hybrid cloud, which is the foundation of a software-defined data center. VMware's new VMware Integrated OpenStack distribution enhances support for an open framework for building and managing the cloud. For Internet unstructured data applications, the VMware VCloud Air Objectstorage is a highly scalable, reliable, and low-cost storage service for unstructured data that enables users around the world to access any device, anytime, anywhere, and VMware VCloud Air SQL is a new database service that supports seamless, secure extensions from on-premises databases to the cloud. Currently, VMware vCloud Air SQL supports MicrosoftSQL Server and will support more relational databases in the future. In addition, VMware has released a technology preview that enables customers to seamlessly manage the hybrid cloud by building bridges between public and private clouds through VMware NSX network virtualization and VMware Public cloud services, VMware VCloud Air, for free migration of networks, applications, and data.

Hyper-convergence is a popular trend today, and hybrid cloud is also a blend of private and public clouds, which re-distributes and optimizes the existing IT resources of the enterprise. With a hybrid cloud, you can offer more selectivity, flexibility, and freedom to enterprise users. From a VMware perspective, building a unified hybrid cloud is everything: http://edu.51cto.com/course/course_id-1034.html, so business users, are you ready?
