New Convenience Cloud Products

A few days ago, a very small number of cloud computing vendors can provide a flexible, scalable, has been available for enterprise practical application of the complete cloud computing products or services. Citrix's new product for cloud computing allows enterprise users to create a new infrastructure for cloud computing, and can be transferred to others for use.

Using the products in the Citrix Systems Company Cloud Suite, IT administrators can manage virtual machine management programs, desktop delivery, federated identities, and user profiles. A private cloud built using Citrix's products has the advantage that all components can be deployed as virtual instances. This means that you can use all the components in a ready-made virtual environment that uses hardware located in a data center or managed facility.

Step one. Management Program Configuration

Whether you use a private server or a managed server, you need to create a virtual environment to build your cloud. After purchasing the hardware, you can install Citrix Company's XenServer management program. The following are some of the key features of XenServer:

• High Availability: The use of a server pool ensures that the system is in a redundant state and that virtual machine (VM) migration can occur automatically between hosts if a failure occurs.

• Storage support: XenServer supports multiple different storage devices and can be managed directly at the graphical user interface level.

• Virtual Machine Management: When traffic peaks and additional virtual machines are needed, administrators can quickly deploy new VMS. They can also configure the server to manage virtual machine mirroring.

Depending on the deployment, the management program can also have several other features. When the management program is installed and running correctly, you need to connect the storage to the newly created mirror.

Step two. Equipment Certification

Citrix's NetScaler equipment is a virtual or physical device. Depending on the requirements of your data throughput traffic or the requirements of your hardware components, make the device an entry point as a virtual or physical device.

Because accessing the cloud computing environment must be secure, you also need to have a strong gateway. The NetScaler device allows you to create a load-balancing server that can handle user connections.

The cloud environment also requires high availability of sites, and NetScaler devices achieve this high availability through their global server load Balancing Technology (GSLB). The ability to connect multiple sites to create a stronger and more stable cloud infrastructure.

Step three. Application Delivery

Once you have completed the configuration of the management program and the entry point, you need an engine to package the application and cloud delivery application packages. Citrix's XenApp 6.5 is a strong thin client that delivers applications to end users. You can install XenApp on a physical or virtual Windows Server 2008 R2 64-bit instance for fast delivery. You can then install and isolate applications, manage user access through active Directory (AD), and allow users to implement seamless applications through cloud computing.

User access is managed through a XenApp network interface. Authentication occurs in an instance of the network interface that is installed in NetScaler or directly in the XenApp window. When you log on to the cloud portal, users enter their own ad credentials, and they are authorized to access a specific subset of the application, depending on the security group they belong to. As long as users can connect to the Internet, they can access the portal from any location, through any device.

Step four. Desktop Delivery

One of the biggest benefits of cloud computing for users is that they can use their own enterprise desktop applications from any location, through almost any device. For example, no matter where the user is, he can use Windows 7 Enterprise desktop applications via an ipad device. By centralizing all host mirroring and using the permissions given to users by cloud computing, they can access enterprise mirrors through personal devices.

With XenDesktop, administrators can create, manage, and deploy host mirrors for end users. Using technologies such as HDX, a video format that improves the speed and quality of flash movies and images on managed desktops, end users can experience truly seamless applications. The desktop applications delivered by XenDesktop are like a dedicated pool environment where users can use either the first available desktop or an ongoing desktop.

When a user uses his desktop through cloud computing, he can also access the personal application that is actually on the XenApp server, and the user is connected to the server when they log on to the desktop instance. For the user, all of this seems seamless, as if the application is always available on the desktop. In reality, the process is independent and managed in the datacenter.

Step five: Federated identity through open cloud computing access

Many organizations run software as a service (SaaS) application in the Citrix Cloud computing environment. Problems occur when users need to remember and enter multiple credentials to access different SaaS applications.

Citrix's Open Cloud Access provides federated identity for cloud computing. By extending the ad scope in the cloud, Open Cloud Access can place the SaaS icon directly on the user's portal, such as Salesforce or GoToMeeting. Then, using a set of existing ad credentials, users can log on to the SaaS application without having to re-enter the user name and password.

Step six: Delivery and management of cloud computing

The recent takeover of Cloudstack by Citrix has made its ability to deliver cloud computing a new step. In addition to cloudstack using your own hardware to provide a public cloud service, Cloudstack is a completely open source cloud computing operating system similar to Amazon's Resilient Cloud computing (EC2). Cloudstack carefully organizes virtualized resources to build a homogeneous environment in which you can remove the creation of different virtual machines through self-service cloudstack portal sites.

Cloudstack enables a secure multi-tenant cloud computing environment; With a single click, you can deploy a virtual server through a preset template. You can turn off, pause, and restart a virtual instance through a network interface, a command line, or a call to extend the Cloudstack application programming Interface (API).

Integrated XenServer products enable more management of the Citrix Cloud computing environment. The console provides administrators with an integrated display of storage, IP pools, CPUs, memory, and other resources. In addition, it can list events occurring in the cloud in a time series to make it easier for administrators to track these events.

With Cloudstack, administrators can make better decisions about how to deliver enterprise cloud computing services. Cloud computing architectures can be dedicated to the entire VLAN to support specific accounts of MPLS between network nodes. Organizations can also create a multiple role support environment so that administrators only have access to the tools they need.

As cloud computing continues to evolve, its cloud-related offerings will continue to evolve. Cloud-computing vendors will also continue to develop powerful new tools for more seamless cloud computing delivery and, more importantly, to provide a stronger and more aggressive use experience for end users.
