Cloud Computing – Is It Safe?

There are essentially two kinds of computing environments:

On-premises computing is the traditional form of computing in which you or your company own and manage your own systems. All the applications you use, as well as your data files, are in your own computers on your own premises either on individual PCs or on an in-house local area network.

In cloud computing, by contrast, your applications and files are held remotely on the Internet (in cyberspace) in a network of servers which is operated by a third party. You access applications and work on your files from your PC simply by logging on to the network.

Cloud services are provided by cloud-hosting providers, companies such as Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure, and so on.

There is nothing fundamentally new about the concept of cloud services. If you are using Gmail, Hotmail or yahoo for your emails, you are using cloud services and probably have been for years.

What is relatively new is the types of services that are being offered in a cloud-environment. These now go far beyond email to cover all the IT services that an on-premises computing environment would deliver, such as accounting, marketing, human resources and so on.

Advantages of cloud computing

Cloud computing has several advantages over on-premises computing:

1) You can run an application or access your files from anywhere in the world using any computer.

2) Cloud computing is cheaper.

3) You need less technical knowledge.

4) Cloud computing delivers a better performance.

5) Cloud computing is eminently scalable. Increasing the number of applications you use or the amount of data you store does not require a heavy investment; you only need to advise the cloud-hosting adviser.

Given these advantages it no surprise that over the last few years there has been a widespread rapid adoption of cloud computing. Analysts estimate that the growth rate of all spending on cloud IT will soon be at least four times faster than the growth rate of all spending on on-premises computing.

Indeed, analysts are expecting the annual growth rate of spending on cloud computing to average 23.5% compound from now until 2017. In addition, by that year spending on cloud services will probably account for one-sixth of all spending on IT products, such as applications, system infrastructure software, and basic storage.

Given the rapid growth in cloud computing, the big question, of course, is whether cloud computing is safe. Is it more or less safe than on-premises computing?

The short answer is that cloud computing is not less safe than on-premises computing. However, the threats are somewhat different in nature, though they are converging.

Are We Too Dependent on Computers?

A computer has been one of mankind’s greatest invention among other inventions ever since the foundation of science began. Its development was a result of years and years of long experiments spanning a hundred or so years conducted not just by one man, but many. Development of computers as it is today is a continuous process and it will ever be. Computers, however simple they may seem now to the computer literate, has a complex set of system underneath. It takes multiple disciplines in both computer studies and electronics to fully understand them. After all, computer in itself is subdivided into branches as is science itself.

While other technological inventions may have had already been developed prior to the foundation of science, “technology” is not yet a proper term for such. The word technology, after all, is always correlated with science and both science and technology are mutually inclusive to one another, strictly speaking in terminologies. Computers of today, however advanced they may seem, have had its origins in humble beginnings.

How did computer began?

Abacus, the earliest form of calculator, has been recorded to be in use since the early civilizations estimated to be around 1000 and 500 B.C., only to be adopted elsewhere in the world. The idea on how the algorithm of a computer does its arithmetic was based on this, in logic. Soon after, for as early as 1820’s, in the personification of Charles Babbage, dubbed to be one of the fathers of modern computer, developed ideas on how computers should do its math, initially known as the difference engine, it developed later after to become what is known as the analytical engine. While Charles Babbage, due to funding issues, didn’t get to see his ideas into fruition during his lifetime, it is his youngest son, Henry Babbage, who did so in 1910 based on his. However, this primitive form of computer is not as advanced as how we see on computers of today.

The idea of the need to do the computation on our behalf as man, hence the word ‘computer,’ came out of the need to handle complex problems and perform complex computations that is both difficult and takes longer time for man to handle. Especially true during the times of the industrialization era and great world war where the need for such arose. How a computer behaves is what’s in a library of a computer.

The development of computer grew by a lot since laying the foundation by Charles Babbage as was inspired by existing “technologies” of its time. From names of people of the past significant in the foundation of computers such as Ada Lovelace, Konrad Zuse, Alan Turing, John Atanasoff & Clifford Berry, Howard Aiken & Grace Hopper, so on and so forth, up to the present computer giant names such as William Gates, Steve Wozniak, and Steve Jobs, among others, computers of today are bigger in functions than they are their sizes and have found a spot in every people’s lives in both commercial and personal usage.

How do people use computers in their daily lives?

Modern day computers laid out the foundation on how we perform duties of today. It is a lot more efficient and makes the work done in shorter times. From a simple household leisure such is playing games or running multimedia programs, to doing office works, to a more difficult developing programs, up to a more complex computations such is done in NASA, computers made all this possible — all in a single box. What once takes a long time to finish in groups as in seen in companies without computers, can now be finished in shorter times with those.

How to Keep Your Computer Cool

When your computer is on, nearly all of its components become hot. Constant exposure to high temperature can cause serious damage to your computer.

Here is a list of ways in keeping your PC cool.

Check if your fans are running.

This is the first step when you find your computer overheating. Open the case, and then check if all fans are still working. If at least one is not working anymore, consider doing repairs or getting a replacement.

Regularly clean your computer.

It is essential to regularly clean your computer, especially the cooling fans. The fans attached inside the computer case is used for active cooling of the computer. Over time, dust and dirt can accumulate in these fans. The accumulate dirt can slow down or, in worse, stop fans from working. If fans fail in expelling the hot air fast enough, some internal parts will eventually overheat.

To clean your cooling fan:

1. Shut down your PC.

2. Open the computer case.

3. If there is excessive dirt inside the computer case, take out the computer fan.

4. You can use compressed air, small electronic vacuum or duster, or damp cloth in cleaning the fan.

5. If you use moisten cloth, make sure that the cooling fan is dry or there is no remaining moisture before connecting it again.

Clean other computer parts as well such as the monitor, mouse, and keyboard.

Before cleaning any hardware component, make sure that your machine is turned off. Otherwise, your computer is susceptible to electrostatic discharge that can damage its parts and you are also prone to grounding yourself.

Before applying any cleaning procedures to hardware, make sure to check its manufacturer’s manual if they have provided you with the recommended instructions in cleaning or maintaining it.

Online Computer Repair and Remote Virus Removal

I have been doing remote computer repair for people across the United States and around the world for nearly a decade, giving PC help to people with malware removal, virus removal, pop ups, or a slow computer. Online computer repair or online virus removal is definitely a time saver and a money saver. Remote virus removal can certainly save a person hundreds of dollars over the cost of taking the PC to a local computer repair shop.

Although using a remote online computer technician is definitely the way to go for PC help, nevertheless there are some pitfalls. I constantly hear horror stories from customers that had previously used an online computer repair service for their computer problems with less than desirable results. Consequently I have put together this list of computer scams to watch out for when contracting with someone to provide remote computer help.

1. USA Based – Really? Most people don’t want to talk to someone in India with an accent so heavy that you can’t understand them. That’s why many websites will say, “USA Based.” But are they really? I have found that many websites advertise they are in the U.S. but the person on the phone, who claims they are in the U.S. still sounds like someone from India. It is not wise to deal with someone who has just lied to you. Hint: Read the text of a website carefully. You will probably find one or two grammatical errors on sites that they are not really U.S. based, and of course, you will know instantly when they answer the phone. Just say, “Sorry, wrong number.”

2. Super Low Price: There are companies out there claiming they can remove viruses, plus fix any and all problems, and do a PC tune-up, all for the low price of $39.99. As someone who has been doing computer service full time for 24 years, I can tell you that it takes several hours for a PC tech to do all that and do it right. How can they do this for such a cut-rate price? There are three ways: 1. Hire a bunch of young geeks that are still learning and let them practice on your computer. 2. Be based in India or the Philippines or some foreign country where labor is cheap. 3. Do the very minimum to just get by without concern for conscientious quality work. Some places do all three. The old adage – “You get what you pay for.” Applicable to online computer repair. If you want good quality remote computer repair you need to pay for it. Try to save a buck and you can end up with a destroyed computer and/or many hours of frustration as you call back over and over to try to get the online computer help you were promised. Good Advice: If you want a good PC tech, don’t pick the cheapest bidder.

3. Certified – Really? Does the website tell you who is going to be fixing your PC? Are the name, credentials and experience of the computer technician posted on the website? I have called some of these supposedly Microsoft certified websites and when I asked exactly which credential was held with Microsoft and the computer service company could not give me an answer.

4. Free Antivirus Software: The online computer service company offers a free antivirus software after the repair. Be aware that they are only giving you something you can get for free yourself. Again, you get what you pay for. Free antivirus software might be better than nothing, but not by much. I remove malware every day from computers that are protected by free antivirus products and they are very infected. Only the antivirus products that you purchase are adequate. When a remote computer repair company gives free inferior products to customers it gives them a false sense of security that will lead to their PC eventually getting hit by a virus. A PC technician that is really looking out for your best interests will offer to sell you a quality product that works.

5. Free Scan Scam: Here’s how it works. You call a remote computer repair service because your printer doesn’t work. The online computer service says they will connect to your machine and tell you what is wrong for free, no obligation. Then you can decide what to do next. Free diagnosis! Sounds good, right? Lots of people fall for this. So the PC technician connects to your machine and runs a program (that they have created) that pretends to do a scan of your computer. In just 3 minutes this software reports hundreds of registry errors, dozens of problems in the event log, dozens of viruses, trojans and spyware. They tell you that you have got to get this fixed right away before all your files disappear and your computer won’t work at all. After the scare tactics, they give you an outrageous price of $300.00. After paying that and they supposedly fix all these errors, chances are your printer still will not work. But the real fact is – there is not a piece of software in the world that can tell you what’s wrong with a computer in a few minutes. I have over two decades of experience and I can tell you that it takes a couple hours of careful work to properly evaluate a computer. I have helped many customers who told me they had just experienced this scam. Fortunately they called me and in many cases their computer was not in nearly as bad a shape as they had been led to believe.
