Three hybrid cloud computing mode public cloud and private cloud power

When the term "private cloud" means a custom-tailored cloud computing technology, most people think that their own data centers are already capable of providing private cloud services. Now that these companies want to apply at least some of the public cloud services, it makes sense to build a hybrid cloud computing next.





However, the hybrid cloud is not simply the application of common technology to establish an equal partnership between the public cloud and the private cloud. These companies want the working application experience to be as straightforward as using an application, which means that either the experience or the application must be integrated into a mixed cloud, rather than how to create a "private" section.




The success of the
hybrid cloud begins with choosing the right integration method.





uses a front-end application to build a hybrid cloud





Create a hybrid cloud-driven strategy that connects traditional data centers with public cloud services involves the use of a front-end application. For example, most companies have established web-based front-end applications to facilitate user access to order entry and account management functions. Many companies also use front-end application technologies such as Citrix systems to combine multiple application components to provide a single custom display for end users. You can use any of these front-end application methods to build a hybrid cloud.





in a hybrid mode based on the front-end application, the application is in the cloud, the data center is working, and integration takes place on the front end. There are no new or complex programs for data integration or resource sharing between a public cloud and a private cloud.





This application front-end integration approach can be applied to all three common cloud models, namely, infrastructure, service (IaaS), platform as a service (PaaS), and Software as a service (SaaS). If the new application is a resource in the cloud, or if you move an existing application from cloud computing back to the data center, you can easily change the front-end application and migrate the data from the new location.





integrated workflow model using mixed cloud computing





The hybrid cloud computing model based on front-end applications has some limitations; it does not allow for resource sharing between the data center and the public cloud. Although a user sees a mixed application group, each application runs independently. If an administrator wants to use a public cloud to back up critical applications or provide additional resources during peak usage, then he should use the integration workflow model.





to create an integrated workflow model, you can use enhanced virtual software with cloud computing resource management components, such as VMware's Vcloud, or expand with most SOA platforms, such as Microsoft, Oracle and IBM products-related resource allocation tools to help identify whether resources are located in the cloud or in the datacenter.





all of these mixed cloud-computing distributed workflow patterns assume that some components monitor available resources and allocate resources for the required tasks. This process enables applications and components to migrate between cloud computing-data centers and within them, so it requires a directory feature to facilitate the service of dynamic application links for end users.





In addition, it is important to ensure that the data that your application requires is available in the data center and cloud computing. For the enterprise, this is the most difficult problem of distributed workflow in mixed cloud computing. Relatively static data can be stored in data centers and cloud computing, but access to Dynamic Data requires data center applications and cloud computing applications to connect to a common repository.





tightly coupled workflows magnify the latency of any communication connection between the Enterprise data center and the public cloud; If you want to improve system performance and reduce latency, this connection will become extraordinarily expensive. Any additional cost will erase the positive implications of the hybrid cloud model for some companies, but Windows Azure is evolving into an integrated workflow model, and it is very likely that most PAAs clouds will follow.





non-traditional Hybrid Cloud computing: Integrated VPN access





A third way to build a hybrid cloud is by using the access mode of an integrated VPN, in which the public cloud computing and data center resources are connected to the company's VPN, allowing end users to access those resources independently. For some, this is not really a hybrid cloud computing model, because the cloud and data centers remain completely independent. However, many companies do not provide integrated viewing of their internal applications, while the hybrid cloud computing model of integrated VPNs replicates their current practice.





Generally, VPN integration is the cheapest and simplest of the three hybrid cloud computing models. When businesses examine the actual business costs and benefits of public cloud computing, they often find that it is the most suitable application for not accessing the company's core data.





Managed Customer Relationship Management (CRM) applications, payroll, personnel, communications, and collaboration applications in cloud computing do not require administrators to integrate any data or applications. It allows companies to focus on it hardware and software investments in core, business-critical applications.





Choose a hybrid cloud model to help you succeed





in order to choose the most suitable hybrid cloud computing model, you need to determine from a financial point of view which application can use the cloud computing resource model. If these applications do not use a large amount of mission-critical data, then these three hybrid cloud computing methods are capable of doing so. However, both front-end mode and integrated VPN mode will be the most efficient, quickest and cheapest choice.




The
Workflow integration model is a better choice for organizations that have access to core data cloud computing applications. In this case, this choice can achieve higher cost efficiency and security.





all three hybrid cloud computing models can be applied to any datacenter application, whether they use proprietary cloud computing technology or not. Enterprises can safely use any of the patterns and develop them as a corporate private cloud strategy and as a concrete implementation of the expansion of the public cloud.  This is the application of the cloud computing a winning model.
