Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information provided to computers and other devices as a utility over a network (typically the internet). Cloud computing seems to have become an umbrella term under which these and other existing solutions marketed. Cloud computing provides computation, software applications, data access, data management and storage resources without requiring cloud users to know the location and other details of the computing infrastructure.
Types of Cloud Computing Services:
SaaS (Software as a Service) delivers a single application through the browser to a plethora of customers utilizing a multitenant architecture. It does not force any upfront investment in buying servers or even in software licensing, which means that costs are drastically low compared to conventional hosting. Salesforce.com is one of the best enterprise applications running on SaaS.
Compared to SaaS, utility computing is not new, but this sort of computing backed by many sites like Amazon.com, Sun, and IBM who host servers on demand. Most companies who adopted it some years back used it for non-critical purposes but slowly and steadily, utility computing is bound to replace datacenters.
Web service providers offer APIs that help out developers to make the best use of its functionality online rather than creating full-blown applications. There are many companies which provide a full range of APIs like Google offers with its Google maps.
PaaS is a variation of SaaS where you can use the platform as a service. You build your applications runs on the provider's platform. One does not get complete freedom here, but one gets predictability and pre-integration.
MSP Managed service providers are the oldest forms of cloud computing. It is an application which manages IT and its applications rather than being useful directly to the end users. The best example of an MSP is a virus scanning service or even a monitoring service and anti-spam services. Even some desktop management services come under the canopy of managed services.
DaaS allows IT to outsource virtual desktops to a cloud service provider. This approach combines simple desktop management, less hardware and increased flexibility and mobility. With cloud- hosted platform IT does not have to worry about the ongoing background technology. Resource provisioning, load balancing, and network issues, for instance, all things handles by a provider.
The cloud-hosted virtual desktop is user interface platform that connects to applications and data which stored on cloud provider's server. Its delivery model Desktop-as-a- service combines benefits for the enterprise. When it comes to cloud-hosted desktop infrastructure, administrators have many choices.
How are cloud-hosted desktops different?
Making the Leap
Cloud- Hosted Linux-based desktops is better than Windows in many ways. Windows requires licensing which is notoriously complex and pricey, frequent hardware upgrades whereas cloud hosted Linux is slim, trim, flexible and scalable, and it performs any computation, regardless of processor or machine architecture. Daas Providers brings own license routes so customers can license software themselves.
Linux can easily reconfigure only to include services needed for your business's purposes, thus further reducing memory requirements, improving performance and keeping things even simpler. Desktop -as-a- service has been gaining its feet in the cloud world. DaaS provides a centrally managed desktop platform without heavy investments in hardware and other upfront costs.
Behind-the-scene patching, updating and ongoing maintenance have included in monthly subscription fee with its multi- tenancy, shared -service architecture. Microsoft combines the Daas licensing process is much easier for large companies because they afford dedicated a server to host their VMs.
On the other hand; Linux is free, and no license agreement required. License management or surprise vendor audits are capable of checking misused software.
The word for Linux
Cloud Hosted Linux Desktop is challenging the perception that it is suited only for the tech- savvy and infinitely patient user. In this, a part perception fueled by Linux distributions like SUSE, Ubuntu, and Red Hat. This platform runs on Linux kernel but adds own desktop themes. Which distributions adopt and which ones to avoid is the common issues in the Linux. There's no clear standard emerging.
With cloud-hosted Linux desktop sorted out these issues by selecting the distributions and maintaining its environment. Users can connect and use their desktops as efficiently as they can in hosted Windows deployments. The subscription firm does not need the technical team to implement Linux desktops, physical or virtual.
Facing a new interface
The Linux version has done some enhancements in usability and now available in a Windows look like and feel but for some user; Linux is still a different OS. In Linux platform employees still require training and support resources. So it becomes an easier transition from Windows 7 to Windows 8. In this shift bite off more than you can chew.
Employees and users leap to a new system for professional use and improvement in their technical knowledge. If people look at day by day improvement on a mobile device in the workplace. In the fact of that organizations have not been adopted Linux desktops because they might not want to invest training and support resources into a system. Also, that is why organization switches back to Windows for toll their roads.
On the other hand, organizations such as the London Stock Exchange, U.S. Department of Defense and Google all use Linux desktops, so possibly they catch on after all.
One more issue that organization might still have to face with hardware support. Many DaaS providers make it possible for customers to extend their networks into the DaaS environment to provide access to corporate resources. However, in this hardware compatibility area Linux has made great strides to become compatible with such device as printers or advanced keyboards.
