Improved Performance Of Computer

Published Date: 02 Nov 2017

If used properly and to the extent necessary, working with data in the cloud can extensively vast benefit all types of businesses. Mentioned below are the pros of this cloud computing technology [39], [43], [51]:

Cost Efficient

The cloud is available at cheaper rates and can lower the company’s expenses than the traditional one. Besides, there are many one-time-payment, pay-as-you-go and some other scalable options available, which make it very reasonable for the company to go on.

Cloud can lower computer costs as it doesn’t need high-powered and high-priced to run its applications. Since applications run in the cloud, the PC can be less expensive on hardware (e.g. smaller hard disk, less memory, more efficient processor, etc.) as well as reduced its software costs instead of purchasing expensive software applications because most cloud computing applications today offers for free.

Improved Performance of Computer

According to cloud computing system, computer in it can run faster and get better performance as just fewer programs and processes loaded into memory.

Almost Unlimited Storage

Cloud computing offers a limitless storage capacity so much of information can be stored in the cloud. Comparing to the hard drive of the current computer, there are hundreds of bytes available in the cloud. Hence, no need to worry about the running out of storage capacity or increasing the storage capacity available like physical storage devices anymore.

Backup and Recovery

Most cloud service providers are usually competent enough to handle recovery of the information which makes the entire of backup and recovery process much simpler and easier than the traditional one. Since all the data is stored in the cloud, backing up and restoring is quite easier than storing the same on another physical device.

Increased Data Reliability

Cloud computing is a data-safe computing platform unlike desktop. If personal computer crashes, all your data is still out there and accessible in the cloud.

Automatic Software Integration

No needs to choose between obsolete software and high upgrade costs as the application is web-based, updates happen automatically and it will be available next time you log into the cloud so you get the latest version without any payment or download an upgrade.

Easy Access to Information/Universal document access

Register in the cloud enables you to access the information from anywhere anytime as long as you have an internet connection. Besides, this is no need to worry of any document because you do not take your documents with you; instead they stay in the cloud so documents are available instantly. This is quite convenient feature enhancing you to move beyond time zone as well as cross over the issues from location based on geographical areas.

Easier group collaboration

Cloud computing enables multiple users ease of collaboration on documents and projects. Consequently, sharing documents on projects lead to better collaboration directly.

Device independence

Cloud computing frees you from a single computer or network as applications and documents follow you through the cloud. Hence, your applications and documents are still available even you move to a portable device.

Rapid Deployment

Cloud computing system gives the advantage of rapid deployment. Once uses the cloud method of functioning, the entire system can be fully functional in a short errand. Certainly, how long does it take depends on the actual type of technology which need for the business.

Contrary (Cons)

In spite of its many and vastly benefits, as mentioned above in pros, cloud computing itself also has its drawbacks. All businesses need to be aware of these cons prior to going in for this cloud computing technology. Mentioned below are the cons of cloud computing [39], [43], [42], [51]:

Technical Issues

The information on the cloud actually can be accessed anytime from anywhere at all, though there are times when system can have some serious issues. In fact, this technology is always prone to outages and other technical issues. The best cloud service providers also face this trouble even they are keeping up high standards of maintenance. Therefore, a very good internet connection is needed to log onto the server at all time. In case of network and connectivity problems occurred, there will be stuck and unable to do anything.

Requires a constant Internet connection

Cloud computing is impossible if no internet connection. Since it use the internet to connect to applications and documents, if there is no internet connection it cannot access anything, even it’s your own files. As a result, a dead internet connection means no work at all and in some areas where as the connectives of internet are few or inherently unreliable, this could be a deal-breaker.

Does not work well with low-speed connections

In addition, cloud computing unable to work at best and frequently impossible by a low-speed internet connection, such as that found with dial-up services. Besides, web-based applications on cloud exactly require a lot of bandwidth to download as do the large documents.

Features might be limited/Inflexibility

In fact, web-based applications naturally are not as full-featured as the desktop-based applications and this situation is confine to modify. For instance, what Google Presentation’s web-based offering is quite confine differences in comparison with Microsoft PowerPoint which offering a lot more to do further.

Could be slow down

Indeed, web-based applications can sometimes be slow even with a fast connection comparing to accessing similar software on desktop PC.

Additionally, anything on program from interface to any document has to be sent back and forth from one computer to the computers in the cloud as well. If the cloud servers are backed up at that time, or if the internet is slow so it won’t be able to get instantly access as expect from desktop applications.

Lack of support

All too many cloud-based applications make it difficult to get customer service promptly or at all. Certainly, sending email and hoping for a response within 48 hours is exactly not an acceptable way for most companies to run a business.

Security in the cloud

The important major issue of the cloud is that security issues. Prior to adopt this technology, should know that all the company’s sensitive information will be surrendered to a third-party cloud service provider. Cloud computing potentially puts the company to greater risk. Thus, make absolutely sure to choose the most reliable and trustworthy cloud service provider ensuring that the information will be kept totally secure.

In addition, with cloud computing, stored data might not be secure as unauthorized users might gain access to the confidential data because all data is stored in the cloud.

Moreover, stored data can be lost eventually data stored in the cloud is safe and replicated across multiple machines but this is in theory. For instance, no physical or even local backup if the data goes missing on the off chance so everything’s gone and nothing left. Basically, relying on the cloud is in risk if the cloud lets it down.

Prone to Attack

Storing any kinds of information in the cloud could make the company at risk of vulnerable to external attacks, hacks and threats. Nothing on the internet is totally and completely secure, thus it’s simply that there is always possibly lurking of stealth of sensitive information and data.

Business Benefits

Cloud services help businesses and consumers free from investing in hardware or install software on their devices. As the solutions are all web-based, it reduces cost of maintenance and hardware upgrades. Even the old computers are able to access cloud services anyway [52].

Furthermore, cloud computing provides an incredible flexibility which enables you to work anywhere from any computing device as long as they have access to the web. This also makes ease of collaboration as information stored centrally in the cloud can be shared via online applications.

Essentially, cloud computing offers the main key benefits as follow [48]:

First, it provides cheap and easily available infrastructure which provided by the third party cloud service providers whose specializes in managing computing resources. This has been called utility computing as its computing and storage on tap.

Second, these resources are managed to be always on and ready to scale by service providers. Indeed, the increasing demand can be met as the provider manages its resource pool professionally. In contrast, unlike self-hosted systems that needs budget approval, equipment ordering, and operations overhead to scaling up which costly and time consume.

Third, business demands can be response rapidly by easy availability enabling it. The cloud provider makes it easy to respond for startups as they offer new services or meet sudden demand. For enterprises, business units can turn IT resources and bypass corporate IT to the cloud which can be easily accessible and collaboration in working field.

For startups >>> Cheap infrastructure and low investment

For Entertainment >>> Highly scalable and temporary systems

(E.g. movie promotional campaign)

For Small businesses >>> Similar motives to startups

For Enterprises >>> Quick and cheap experimentation

Future Trend

Cloud computing is now evolving like never before, with companies of all shapes and sizes adapting to this new technology. Industry experts believe that this trend will only continue to grow and develop even further in the coming few years. While cloud computing is undoubtedly beneficial for mid-size to large companies, it’s not without its downsides, especially for smaller businesses [52].

Many of activities loosely grouped together under the cloud computing have already been happening and centralized computing activity is not a new to this world.

Grid Computing was the last research-led centralized approach, however there are concerns that the mainstream adoption of cloud computing could cause many problems for users.

Many new open source systems appearing that it can install and run on local cluster which actually should be able to run vary applications on these systems somehow [39], [53], [54], [55].

In addition, more scripting languages would be integrating soon as well as the increasing numbers of data center volumes, hence we then might see open source cloud computing (Red Hat) and Salesforce for Google apps too. After all, cloud computing can help reduce global warming as well by Going green concept [57], [53], [54], [55].

SMEs and Cloud Computing

Outsourcing IT functions such as payroll, website hosting, email, or enterprise resource planning (ERP) has long been normal for businesses of all sizes. But outsourcing critical IT functions including database servers, file servers, document storage, or application development, gives many organizations pause [39], [44].

Many experienced IT admins point to recent well-publicized outages, data losses, and hacking incidents that have cost companies big in lost productivity, lawsuits or penalties and even leading to bankruptcy. Yet, there are substantial benefits to gain through lower costs of infrastructure, utilities, and administration as well as better availability of services, especially from outside the corporate firewall. Here are the savings you can realize with cloud services [40], [41], [43].

Cloud computing is a great opportunity for small businesses to off-load the hassle complication and costs of IT management as long as they can live with the cons. Indeed, security issues related to having their business data out on the internet seem to be the number one concern of small business owners [41], [44], [45].

Cloud computing is a playing field leveler which gives small businesses access to technologies that previously were out of their reach from high costs etc. and lets small businesses complete with both other small businesses or even larger ones. And to make the deal even easier, smoother and sweeter, this cloud computing can also save small business money too [39], [52], [45].

Consequently, one approach might be to begin cloud computing slowly and reasonably by choose one or two of business applications to replace then see, visualize, and recognize how it goes. Expectantly, hope that over time will make company more comfortable and familiar with it and also able to gain and harvest even more pros of cloud computing [39], [52], [45].

Opportunities for SMEs

Save on Infrastructure

Rather than buying new servers, operating systems, and applications to provide IT services in-house, you simply pay a monthly fee to a cloud provider. Considering that the cost of one server with OS and applications can be a couple of thousand to tens of thousands of dollars, this can be a huge benefit, especially if you want to test a new service before a full implementation [44].

Save on Setup and Management

If your IT staff is unfamiliar with a new OS or application, it can be a long, arduous process to implement a new function. Cloud providers have experienced administrators who do nothing but support specific applications. This is one of the reasons for the popularity of cloud-based ERP services which are notoriously difficult to set up, both in getting hardware and software modules to work together and in configuring the software properly. Likewise, for third-party cloud providers with enough experienced staff, routine chores like monitoring, setting up new accounts, or applying patches are no problem [44].

Save on Utilities

Because cloud providers use large, modern data centers with green features and share infrastructure among multiple companies, their costs to run the small part of the center you’re using is much smaller than your costs would be for a server that's likely under-utilized in your own data center [44].

Get Better Performance, More Features

Since cloud providers are providing services to many different companies, they buy large, high-performance systems that offer performance levels much higher than a small company can afford to run internally. They typically have the most capable versions of software and site licenses, so they'll also have access to features at much lower costs than you’d be able to get in-house. Their experienced administrators are more likely to know how to optimize performance than your company is, especially if your IT department consists of one person who also doubles as the art department [44].

Increased Company Agility

Cloud providers can add servers or services quickly and easily, and make them available not only to your internal corporate users but to external contractors, partners and customers as well. That means you can achieve degrees of flexibility that would be difficult or impossible internally, allowing you to respond more quickly to your customers’ needs or changes in your core business.

Enjoy More Fault Tolerance

Cloud providers can afford to have multiple data centers, multiple Internet connections at each data center, as well as replication of data between data centers. Plus, they can offer levels of data protection far beyond simple nightly backups, such as continuous data protection, generators to handle power outages, and high-end servers that can keep running even one component fails.

The savings that cloud services bring can be dramatic, not to mention other benefits, such as additional features and better agility. Just keep in mind that these benefits may be offset by the chance of losing data if the cloud provider has problems. You can balance the risks by adding fault-tolerant options, either through the cloud provider or by having them back up your data to another provider. In the end, you’ll have to decide how much potential the applications you’d like to move to the cloud have to disrupt your business if they’re not available [44].

Conclusion

It’s like everything else, exactly cloud computing too has its pros and cons. While this technology can be proven as the great asset to company, by the way it could also definitely cause harm to any kinds of its users somehow onward if not understood it well and used properly [45].

Cloud computing is a better way to run your business. Instead of running your apps yourself, they run on a shared data center. When you use any app that runs in the cloud, you just log in, customize it, and start using it. That’s the power of cloud computing.

Finally, cloud apps don’t eat up your valuable IT resources, so your CFO will love it. This lets you focus on deploying more apps, new projects, and innovation [58].

Cloud computing is here to stay. The specific roadmap for the technology might be still unclear, but the fundamental economic and business forces that shape the computing industry point to a logical conclusion: many computing applications are general-purpose in nature, and therefore offer tremendous economies of scale if their supply can be consolidated. While the researchers and practitioners in the computer science community are making rapid strides in realizing this conclusion in technological terms, we believe that an equally important discussion needs to start from a business perspective. In this article we have tried to identify the different issues that will affect the various stakeholders in this radically different computing paradigm. In the process, we have attempted to come up with a set of recommendations for businesses and academics alike, with a passionate call to the latter community to start researching proactively in the issues that will affect the various stakeholders. Unlike some of the previous waves in computing, cloud computing also demands a thoughtful and coordinated response from governmental agencies [49], [50].

The fluid and uncertain environment that surrounds cloud computing, be it in terms of the technology, its adoption, the industry structure or the regulatory regime that will eventually need to be in place, makes such an exercise that much more difficult. We however hope that our attempt to look at the phenomenon through a business perspective reduces some of the uncertainty surrounding the phenomenon, and more importantly jumpstarts the discussions on the various issues that we have identified [49], [50].
