CLOUD computing concept



CLOUD COMPUTING comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.




Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging.


InfoWorld talked to dozens of vendors, analysts, and IT customers to tease out the various components of cloud computing. Based on those discussions, here's a rough breakdown of what cloud computing is all about:


 1. SaaS
This type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting. Salesforce.com is by far the best-known example among enterprise applications, but SaaS is also common for HR apps and has even worked its way up the food chain to ERP, with players such as Workday. And who could have predicted the sudden rise of SaaS "desktop" applications, such as Google Apps and Zoho Office?

2. Utility computing
The idea is not new, but this form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs, but one day, they may replace parts of the datacenter. Other providers offer solutions that help IT create virtual datacenters from commodity servers, such as 3Tera's AppLogic and Cohesive Flexible Technologies' Elastic Server on Demand. Liquid Computing's LiquidQ offers similar capabilities, enabling IT to stitch together memory, I/O, storage, and computational capacity as a virtualized resource pool available over the network.

3. Web services in the cloud

Closely related to SaaS, Web service providers offer APIs that enable developers to exploit functionality over the Internet, rather than delivering full-blown applications. They range from providers offering discrete business services -- such as Strike Iron and Xignite -- to the full range of APIs offered by Google Maps, ADP payroll processing, the U.S. Postal Service, Bloomberg, and even conventional credit card processing services

4. Platform as a service
Another SaaS variation, this form of cloud computing delivers development environments as a service. You build your own applications that run on the provider's infrastructure and are delivered to your users via the Internet from the provider's servers. Like Legos, these services are constrained by the vendor's design and capabilities, so you don't get complete freedom, but you do get predictability and pre-integration. Prime examples include Salesforce.com's Force.com, Coghead and the new Google App Engine. For extremely lightweight development, cloud-based mashup platforms abound, such as Yahoo Pipes or Dapper.net.

5. MSP (managed service providers)
One of the oldest forms of cloud computing, a managed service is basically an application exposed to IT rather than to end-users, such as a virus scanning service for e-mail or an application monitoring service (which Mercury, among others, provides). Managed security services delivered by SecureWorks, IBM, and Verizon fall into this category, as do such cloud-based anti-spam services as Postini, recently acquired by Google. Other offerings include desktop management services, such as those offered by CenterBeam or Everdream.

Here are some benefits that you could get by investing on the right kind of cloud computing solutions.


  • ACCESSIBILITY  
The thing about cloud computing solutions is that it is literally run over a series of networks, meant to link various devices with each other. These devices – be they laptops or phones or desktops – are connected via internet.
This entails a hassle-free kind of network support as multiple deals could be dealt with simultaneously from the comfort of any place you desire. The caveat of a necessary internet connection withstanding, this promotes the accessibility that cloud computing solutions could offer to your company.


  •  EFFICIENCY
Not only is cloud computing solutions cost-effective (given the fact that this is a specialized, systematic service that can be manned and managed by minimal expert staff on payroll) but also efficient in terms of time management and availability.

Cloud computing solutions, once established, can mean that you can get much more work done faster and with less people required. When too many people are working on the one thing, it can get quite sloppy and misguided. When fairly distributed and categorized, compartmentalizing the labour through these solutions will merit immediate efficiency with fast results.
There will be minimal need for new software, what with the connection of programs through the cloud; these solutions could be tailor-fit to the needs and betterment of your company.


  • FLEXIBILITY
Should any of your current plans fail – or there should there be a new direction that your company needs to take – cloud computing will make the transition that much easier, with the flexibility that this service can provide. The resources that are provided will be maximized and can be fully tailored with whichever direction you should wish to take.
Your company’s inner infrastructure will not falter nor fail for the cloud computing solutions services offer a firm foundation to which you can twist and turn to your leisure. Perhaps you meet a method that beckons a different strategy in order to reach a particular goal – cloud computing will make integration of devices and network services that much easier with its synchronization and maximization of resources. No hassle, no fuss – and it all comes at lightning quick accessibility.
Investing in these innovative cloud technology services are aimed and dedicated to benefit you in the long run. It’s simple, really – or CMS IT can make IT simple.
