Setup of Ubuntu 10.10 Server version Cloud Environment

In fact, starting with the Ubuntu10.04 version, canonical started to offer cloud services through Ubuntuone, offering 2GB of free online storage and, if you want more space, paying an extra fee to buy. Cloud computing in recent years from a somewhat vague concept, gradually rise to the use of the stage. This makes every it vendor see infinite Business opportunities, canonical naturally also refused to ignore this sumptuous feast.


　　


after the Ubuntu10.04 to taste the benefits of cloud computing, the Ubuntu10.10 has increased the cloud services, but also increased the cloud US cloud computing manufacturers Amazon's cooperation. Ubuntu is now the most popular server operating system on the AmazonEC2, and Ubuntu already has a strong cloud support capability designed to deploy more directly to public and private clouds, according to canonical.


　　


so, from the Ubuntu10.04 server version of the operating system to today's latest version of the Ubuntu10.10,ubuntu are in what way to highlight their features. Below, we analyze cost, system integration, management, virtualization, and security.


　　


1. Reduce costs: Reduce the cost of each phase: The Ubuntu server achieves an effective architecture with fewer resources, it simplifies maintenance and updates, saves hours and poor license and subscription costs, and lowers ownership costs. And, by visiting the world of one of the best open-source applications, your IT budget goes further.


　　


2. System integration: Ubuntu Server Edition can mix ubuntu, Windows, or OS client environments. All customers share user authentication, Exchange documents and access services, and open source LDAP (Lightweightdirectoryaccessprotocol, Lightweight Directory Access Protocol), similarly, open source Pam ( Pluggableauthenticationmodule, plug-in verification module) user authentication is considered standard.


　　


3. Management: Such operations as startup, shutdown, and package management are simplified to single commands. After a few seconds, the deployment is reset and the service is acquired. After a few minutes, establish industry-standard mail, network, DNS resolution, files, virtualization, Java applications, cloud infrastructure, or database servers in minutes. With a picture you can manage a server farm like a single server.


　　


4 Virtualization: It's easy to virtualize your server with Ubuntu Server version and KVM. Use secure and concise Ubuntujeos as a client operating system. With support for KVM, Xen, VMware, and LXC, you can use your favorite tools.


　　


to configure AmazonEC2 with UEC (Ubuntuenterprisecloud,ubuntu Enterprise Cloud) or with Ubuntu Server version mirroring, you can build a flexible and efficient computing environment in your own infrastructure. Canonical provides a full range of services to assist the organization in the design, construction and maintenance of UEC.


　　


5. Security: In an Ubuntu server, a secure way means that special users and programs can gain access to the operating system's license. The less complex firewall technology makes access security still simpler, while at the same time adding a layer of security to a home and private directory encryption service.


　　


so, compared to the previous version, specifically to see what the Ubuntu10.10 Server version of the operating system did the major improvements?


　　


, which extends the canonical Cloudinit Configuration tool, allows you to set the default locale, hostname, generate and set the SSH private key, and set up the mount point for Ubuntu when it starts in the cloud.


　　


Second, you can make Amazonmachine mirroring (which is actually an Ubuntu server running on a EC2 service) and run offline on a KVM virtualization system, which means you can develop and test servers for core content without paying Amazon any fees.


　　


The third, containing Eucalyptus2.0, is the latest version of the core cloud technology used in Ubuntuenterprisecloud (UEC), and UEC is a private cloud solution for canonical.


　　


Note: Eucalyptus is an open-source software infrastructure to implement cloud computing. Eucalyptus is an open source implementation of AmazonEC2 that is compatible with the EC2 business Services interface.


　　


four, supported by UEC Virtio,virtio is an I/O virtualization framework that provides hypervisor abstraction and a common set of I/O virtualization drivers.


　　


, five, integrates Glusterfs and Ceph, where Glusterfs is a general-purpose distributed file system for mass storage, and Ceph is a distributed file system with no single point of failure.


　　


Super Ease of use, is the key to Ubuntu as a Linux desktop operating system, and the Ubuntu Server version of the operating system, in the focus on its own transformation into a cloud computing operating system, but also adhere to from the simple, universal and so put a lot of energy. 123 Next Page
