Cloud Computing And Its Role In IT Infrastructure

What Is Cloud Computing?

Under the traditional IT infrastructure model, an organization maintains a data center which provides IT resources to end users. Under a cloud computing model, the organization connects to a data center operated by a third party. These data centers serve many clients, with each drawing the resources they need from the computing complex.

A common metaphor is the electrical grid. Traditional servers are like getting your electrical power from onsite generators, with all the operational and maintenance headaches that go with it. Cloud computing is like getting power off the grid. You don't operate the generating resources or even know where they are. You just get the power you need when you need it

Cloud computing is a type of data center colocation. Some colocation plans give clients access to specific servers in a designated location. Cloud computing is colocation, but with access to servers shared among many clients.

Advantages Of Cloud Computing

Cloud computing data centers are more reliable because clients are no longer dependent on a limited number of servers. If one server goes down, others automatically pick up the load with no interruption of service. Redundant connections and power supplies keep the network running smoothly, and multiple server locations ensure that even a fire or other disaster can't cripple the information network.

Cloud computing creates a scalable IT infrastructure environment. Clients have scalable access to the computing resources they need, no more and no less, so their IT capabilities grow as the company does. Centralized application access simplifies maintenance, since IT personnel no longer have to update each user's computer. Professional management of data center colocation services allows clients to save money by operating with a smaller IT department.

Technology Concerns

Security and privacy are two of the top issues cited by companies reluctant to adopt this kind of technology, especially those in companies falling under stringent federal regulations such as HIPAA or Sarbanes-Oxley. Does that mean the cloud is insecure? No.

In many ways, these types of colocation makes data more secure. Most colocation providers offer a level of physical and data security which wouldn't be cost effective for their clients to provide themselves. However, security and privacy are less about the technology than they are about the provider. Ensure you retain full ownership of your data so you don't discover the cloud computing provider has been selling off your client lists, and only use colocation services located in the U.S. We take for granted the laws which protect information privacy in this country and may forget that IT operations based in other countries are not covered under those same laws. Choose a respectable and experienced provider, and you won't have to worry about security.

Cloud computing may seem new, but it is simply a different term to describe data center colocation and virtualization technologies which have been around for years. The technology is a viable IT infrastructure solution and is reliable, safe and secure when deployed properly.

What Is Cloud Computing Technology - Should Small and Medium Businesses Switch Over?

The Importance of Cloud Computing in Small and Medium Sized Businesses

Most small business owners have problems on the information technology aspect of their companies especially the cost of running their own websites and servers. Small business owners need an affordable, flexible and effective solution to enhance the capacity of their businesses. Therefore, it is the best solution to help SME's in overcoming the different business issues.

Business owners with limited budgets and knowledge about this kind of technology can acquire support for all their business issues. These virtual computing resources are provided through online servers and data centers that give stable service to users with access to the network.

SME's can manage their IT budget without paying a lot of money through cloud computing services. The most popular cloud computing providers are Google, Yahoo and Amazon. Given the usefulness of this sort of technology infrastructure, it is not difficult to know the importance of this for small businesses.

Cloud Computing Offer Competitive Advantages

Most businesses typically utilize this innovative development for services which are related to data storage. Small businesses are continuously gaining quite a lot by utilizing into cloud resources to improve many aspects of daily productivity. There is no need for business owners to establish an expensive IT department just to keep their business going. These services give the handful of cloud computing benefits to your businesses.

Highly Automated IT Management

Most businesses are facing the problems which are related to a variety of system updates and backups. Businesses may have problems in updating their data and keeping their backups. With cloud computing, you do not need to worry about system updates and backups because the system itself will automatically do this for you. This technology will fix your problems on its own to give the business more time to do its main job than just resolving business issues.

Helps Business Become Flexible

The employees can have easy access on the data and other things related to the business anytime and anywhere. They can do important things needed in the business and at the same time, they do the cloud computing. This is considered as the best technological benefit being given by cloud computing to businesses.

Reduction in Expenses

Through the effective utilization of cloud computing, the expenses in business operation will be reduced. It will allow you to plan the needed expenses with appropriate budget. Keep in mind that it is important to only pay for the things you used. You will no longer worry about other expenses because through this technology, what you will just use is the only thing you will pay for. Some business owners are being forced to pay for whole services but after the operation it turns out that they did not use all of the services you paid for. This simply means that they are paying too much for services that they did not actually use. Through cloud computing you will only pay for the services that you used.

Time Saver

The system used in cloud computing is not complicated. It would give you more time to focus on other aspects of your business. You should keep in mind that time is really important. It is best to choose a system that will save your time so that you can give time to other tasks.

Leverage Cloud Services and Save On Unnecessary Overheads

It is impossible to run a business today without computers and that is common knowledge. But computers cost. Cloud services are a cost-effective alternative. Even though the cost of computers is getting lower everyday, any decrease in cost is being negated by the demand for faster computers and businesses end up paying the same anyway. So they offer a kind of 'rent computing power' service. This way, businesses can leverage the benefit of high-computing power and speed only when they actually need it and accordingly pay for it only as and when they use. This will save them from purchasing expensive machines and servers.

What do these services exactly do is move the computing power to a remote location, leveraging the connectivity offered by the internet. The term 'cloud' in fact refers to the internet. Cloud services is a system where the computing work is shared by several computers or the computing power of the computer is augmented briefly by a server. If a company's process is such that it requires high computing speed, but not always, only at specific short periods in the process, then they should consider cloud services.

For small businesses and start-up companies, the best cloud services are those that have plans optimized to meet the requirements of these small time companies who do not have the deep pockets of bi multinationals. In fact, cloud computing isn't even used by major companies who can afford the luxury of buying their own high-tech hardware. They also have to be secure, since they will have access to the intellectual property (IP) of a company and companies do not want their trade secrets let out.

Hence, in a shared environment, security is of utmost importance and the [http://www.cloudservices-florida.com/]cloud services provider should act accordingly and retain the faith of the client companies.

Is the Cloud Right for Me?

With many people, startups, and media raving about the Cloud, as an Information Engineer I find it is important to weigh both the advantages and disadvantages of any technical solution. There are a number of disadvantages as well as excellent advantages to Cloud based solutions. Some of the disadvantages being privacy, security, and performance (network). Some of the advantages being initial startup cost, manageability and speed.

What is the Cloud?

Everyone's definition of the Cloud is different, and I do not to intend to define it, but rather note a few commonalities I have seen in the wild about what the cloud is, and what it means to the average individual, business, and engineer respectively. For the purposes of this article, we will consider the cloud to be any hosted application, API, or server which is managed by a third party, and often times run on a virtualized infrastructure.

What make the Cloud great

The Cloud is an excellent resource for many companies and organizations looking to implement a low-overhead IT infrastructure in a short amount of time, with a small amount of initial investment. One thing that many companies don't realize; however, is that the cloud is by no means a silver bullet to all of their IT problems, and can in fact be more expensive in the long-term.

Cloud computing allows many companies to test new products and services in a short period of time, without having to lease data center space, set up a network infrastructure, get an IP netblock from their Regional Internet Registry (which is even harder now that the IPv4 pool has run out), set up a virtualization infrastructure, and configure their servers; which is what is required to get the equivalent of simply entering your credit card information and spinning up a cloud-based server instance or application.

However, for many companies having a dedicated set of hardware and IT staff or consultants to manage it will often times be less expensive in the long term, and their data will in fact be safer and perform better, depending on their business needs.

Auto-scaling? Is it real or a myth?

Real Cloud Costs

If you rely solely on the Cloud, all of your intellectual property is in another organization's control (companies go bankrupt, mistakes do happen even for the big guys, etc ). We have seen problems with this such as when Flickr lost a user's account. Everyone makes mistakes, even cloud providers, although unlikely. The simple fact is that when your information is on a third party system, you have much less control over your data.

The costs of the Cloud have a breaking point, an average high-end Web or app server is about $4,000 including the hardware and software required to run it, not taking into account leasing a space at a data center, purchasing the networking equipment and paying for bandwidth, which contrary to popular belief, can be done relatively cheaply. The cost of a reserved high-CPU instance is $1,820 per year. If you replace your hardware every three years, then Amazon's EC2, for example ends up costing $5,460, and there is no equity in the equipment which can be sold when it's decommissioned. For most businesses purposes, the hardware likely won't need to be replaced after 3 years, but every business's hardware refresh policy is different. The bottom line is, although EC2 has a much lower start-up cost in the first year, over the long term it is actually more expensive, without taking the cost of hiring IT staff or consultants on to manage the system, which can drive up the management cost.

Cloud Performance Concerns

Many servers and services hosted in the cloud are shared resources. Although many cloud providers do know what they are doing in terms of balancing resources, there is the possibility that other tenants on a shared host could consume resources affecting your machines performance. Also, for most cloud instances, the network bandwidth speeds are painfully slow, so if you have to transfer a large amount of data, it can take a long time. Whereas if you have your own network and AS number, you can get extremely high rates of transfer between multiple sites where your systems reside.

Another concern is security. Although many cloud providers offer SSL for managing instances, it can be difficult to manage something like a directory infrastructure using the cloud. Typically, authentication systems such as LDAP, even though it can be ran over SSL, is not something that you want exposed to the public Internet. SSL is still susceptible to man-in-the-middle attacks [1].

Benefits of the Cloud

The cloud is an excellent resource and advancement in computing. It allows companies and individuals alike to spin up servers and application platforms in a heartbeat, without all of the overhead and complexity of managing the service themselves. Although the cloud is not a be-all-end-all solution to IT problems. Like any technical solution, it has to make sense for the business or organizational goals at hand, and depending on the projected lifetime of a project, product, or service, the cloud may or may not be the right solution. For small projects, test launches, and small business, it may make sense; because the entry to market is much lower.

Even Github.com, a large source code hosting service built on cloud computing technology utilizes dedicated servers in combination with cloud-based servers. Many organization may find that a hybrid solution such as Github's works well for them, but one must weigh the benefits and needs of the business against performance, cost, security, and lifespan of a project before making a decision. Generally, long-term projects and core infrastructure is best hosted on dedicated servers, and short-term projects, for startups, or projects that are testing a new product or service are well suited for the cloud, but extra measures must be taken into account for the security of the service or platform.

With many businesses today your office is wherever you are. In the natural progression of technology - the cell phone, laptop, Wi-Fi and cloud computing - telecommuting is quickly becoming the norm for many businesses.

Coffice. Yep, that's what they're calling it. When you go to a coffee shop and use it as your primary internet connection for business purposes, it's a coffice. What a wonderful atmosphere! And, let's face it, who can beat that fresh baked bread smell? It can be a less stressful place for meetings, too. Sometimes that neutral environment it just what's needed to facilitate improved communication.

What's your favorite coffice location? Something Panera Bread Company has to offer over other coffee shops is their wide selection of foods and drinks. Just smelling that fresh baked bread stimulates your creative juices and makes an open, friendly environment for meetings that could otherwise be tense or boring due to the atmosphere alone. And then, when your energy begins to lag in the afternoon, great coffee or other drinks await, virtually at your fingertips!

Why Panera Bread Company? Free Wi-Fi, of course! Sure, there are other coffee shops that offer free Wi-Fi access, but is it free and do they have the wonderful bagels, sandwiches, soups and desserts Panera Bread Company is known for? Probably not.

Area sales reps constantly travel within their region making sales and staying in contact with their customers. Often there are files they truly wish they had but hate to drive back to the office to retrieve. Through various programs, including Log Me In, with Wi-Fi access the rep could refresh with a cup of coffee while accessing their desktop remotely. Need a file printed? No problem! Send it to an area print center (Kinkos, UPS, Office Depot...) and pick it up on the way to the meeting.

Professional speakers who fly from city to city speaking at various conventions and conferences could also benefit by cloud computing from their coffice. Wi-Fi is where it's at! Checking into your flights online is just one example. You can even download handouts and flyers stored on a remote cloud drive (Mozy, DriveHQ), order prints and have them ready and waiting at the hotel upon your arrival; all the while sipping your favorite coffee in your favorite spot at in any city - the coffee shop with Wi-Fi.

The Six Benefits of Cloud Computing

In my opinion, the benefits of cloud computing clearly include the cost savings that come with economy of scale, but also include a number of other benefits. Here are the Six Benefits of Cloud Computing as I see them:

Lower Costs - Cloud computing pools all of the computing resources that can be distributed to applications as needed - optimizing the use of the sum of the computing resources and delivering better efficiency and utilization of the entire shared infrastructure.
Cap-Ex Free Computing - Whether you go with a public cloud or outsourced private cloud computing option, cloud computing delivers a better cash flow by eliminating the capital expense associated with building the server infrastructure.
Deploy Projects Faster - Because servers can be brought up & destroyed in a matter of minutes, the time to deploy a new application drops dramatically with cloud computing. Rather than installing and networking a new hardware server, the new server can be dialed up and imaged in through a self-serve control console. Or better yet, with a rel=nofollow [http://www.onlinetech.com/managed_servers/private_cloud/]private cloud, your service provider can dial up a new server with a single call or support ticket.
Scale as Needed - As your applications grow, you can add storage, RAM and CPU capacity as needed. This means you can buy "just enough" and scale as the application demands grow.
Lower Maintenance Costs driven by 2 factors: Less hardware and outsourced, shared IT staff. By using less physical resources, there is less hardware to power and maintain. With an outsourced cloud, you don't need to keep server, storage, network, and virtualization experts on staff full time. You get economy of scale of those expert resources through your cloud provider.
Resiliency and Redundancy - One of the benefits of a private cloud deployment is that you can get automatic failover between hardware platforms and disaster recovery services to bring up your server set in a separate data center should your primary data center experience an outage.

Cloud computing provides some strong benefits. Selecting a public or private cloud implementation will depend on your application, performance, security and compliance requirements, but with the proper deployment, it can provide significant savings, better IT services, and a higher level of reliability.

The Future of Retail Industry is in Cloud Computing

Although everyone is familiar with information sharing through internet and worldwide web, performing all the operations of computing through the internet is not so familiar. Cloud computing exactly does the same. It shares information, software - applications and operating system - and infrastructure - hardware like servers and storage units - using internet. A revolutionary cloud computing model can avail high power computing to the customers who need to have only typical input/output infrastructure.

Software industry giants have already started providing their services on cloud. CRM of salesforce.com, office applications from Microsoft and Google and IBM enterprise solutions have already become popular. Sadly, retailing - one of the largest sectors of the economy - has not yet begun its experiences with cloud computing.

In the context of retail industry, cloud computing is particularly efficient in collection and analyses of huge volumes of sales data and in real time inventory management.

In retailing, points of sales generate large amounts of data each day. The sales data can be obtained through loyalty cards and discount coupons also. Most low and medium level retailers do not have the necessary resources to capture or utilize such enormous amounts of data. Cloud provider in retail can collect such data from sophisticated server networks connected to the supply chain to independent cash registers at family owned small stores and store it for the retailer. Such stored data may be accessed from anywhere, provided internet is accessible. A cloud computing provider can track performance of products in comparison to previous time periods. The cloud provider can identify the trend and seasonality component of each product, brand or category and identify and monitor the performance. Then it can provide analytical results to the retailers. The provider of the service can serve many retailers at the same time, without making each retailer do it individually for themselves.

The sales data collected from the point of sales is currently under-utilized. It is more due the incompatibility between volume of data and the processing power of the system. Such time consuming analyses fail to provide any useful insight in to customer behavior or trends in sales. The cloud provider can utilize high power computing resources and statistical models to analyse data in much shorter time. This is more so with to real-time analysis. Real-time analyses require huge capital expenditure and it incurs significant operating cost, often unaffordable to retailers.

A good cloud provider can easily help the retailer in understanding patterns and trends within large databases. It can be further utilized for creating analytical models, and to provide an edge to decision making. Thus retailers can increase their ability to forecast their customer's behavior and plan accordingly. Retailers can then develop customer programs, marketing, merchandising and pricing strategies to attract more business. The cloud provider themselves design and provide such retailer specific plans.

Another important area of cloud application will be inventory management. Real time data and cloud architecture will largely reduce the problems like stock outs and overages. As well known, online retailers do not have inventory managed by themselves. Instead, it is done by the manufactures. Cloud computing can provide an efficient utilization of logistics, which will keep losses to the minimum in inventory management. What the online commerce does can be extended to whole of retail sector. Besides, as the cloud provider will be serving numerous retailers, they can very well manage difficult situations like stock unavailability. Cloud providers can provide valuable advises to retailers regarding product availability and back-up stock from forecasts. They can get realistic forecasts by analyzing huge amounts of data from numerous retailers. Thus retailers can develop a supply chain where the right product arrives at the right time.

Tier one retailers can save lot of expenditure in IT management, if they switch to cloud computing solutions. The complexity of keeping and managing individual systems can be avoided. Today large retailers struggle to keep tens of thousands of computers across hundreds of locations. The management of such a complex system causes enormous expenses for them. Such operations often cause poor decision making in their field of competency - retailing. Large expenses of management and administration of IT and networks can be reduced by simply switching over to a trusted cloud provider.

What is the difference between cloud computing and traditional model? Cloud computing has a number of advantages over the traditional software business in which retailers get licensed software installed in their systems. Here the retailers need not spend huge money on software licensing. They need not buy high end servers with high computing powers. There is no requirement of sophisticated storage units. The administration and networking of computers can be avoided. The pain of providing fire-wall and antivirus protection is avoided. Thus a there can be a significant reduction in investment as well as in operating costs.

One significant benefit for the cloud provider will be that of scale. Affordable solutions can be provided, considering the huge number of retailers in the industry. Most of the tasks to be performed by the provider will be of repetitive nature. Administration and management of databases can be easy due to centralization. The robustness of the whole system can also be ensured. Security and other reliability threats can be minimized due to the salient features of cloud architecture

The future of the cloud in retail starts with small retailers. Small retailers can effectively implement cloud solutions faster. Such solutions offer them significant cost reductions also. Any new venture in retail will also look for quick and easy implementation. An established cloud provider with a successful cloud model can provide quick and cheap solutions. The giants in retail industry may hesitate to adopt the cloud solution, considering the current maturity of the technology. With improvements in cloud applications as well as in internet technology, they will find it cost-effective to switch over. It is significant to note that innovations in most of the fields are taking place in the cloud computing model, not on traditional software business.

Retail cannot shy away from the emerging and powerful trend in the world of computing. With lots of cost-saving and time-saving measures, it will be inevitable that retail will adopt cloud computing once there evolve competent solutions.
