The choice of where to keep electronic achieves and backup copies of corporate data is of current interest for each company. Whether they are to leave within a local data-processing network or to bide data into the external data centre (EDC)?
Today it has become possible to use resources of even foreign EDC operators, which offer services on storage in a few data-centres connected between each other through high-speed data lines.
Have you already decided on using cloud storage? Or, perhaps, are still thinking, weighing all the pros and cons? This article is aimed at helping to describe all the pros and cons of Cloud service. Let us begin with the pros.
1. Cheap equipment
There is no more need to buy expensive computers with a huge capacity and much memory, CD and DVD drives are no longer needed just as well. From now, all your data is to be stored on «cloud» and this is where the majority of calculations are to be made. Users do not need bulky computers or laptops anymore, because now a mini laptop is everything they need for work.
2. The increased production output of personal computers
As long as the majority of programs are to be launched remotely, through the Internet, there will always enough available resources on a computer. In the estimation of professionals, it reduces the workload onto a computer about twice.
3. Expenses decrease and IT infrastructure efficiency upgrading
Ordinary companies’ servers are loaded no more than 15% of their capacity at average. However, in particular cases, there is a need for additional computational resources. Therefore, the companies` servers either stand idle for a certain time or are not on the job. When passing to cloud computing, this unreasonable waste of resources will be solved. Now you are going to use the required number of computing resources, while expenses for equipment and maintenance will be 50% reduced. This is one of the stronger points which many cloud hosting providers use to attract customers to use their services as custom data plans become more and more relevant as your company grows bigger. If a big company will be peeved about its data to be processed elsewhere, such a company might have a cloud of its own.
4. Minimization mishaps with service
There are less and less physical servers with each year (with Cloud Computing technology), which is why they become easier and faster to maintain. When it comes to software, it is already installed, set up and constantly upgrading on the «cloud».

5. Cost minimization for purchasing software
Now instead of constantly buying new programs for all the employees, it is enough to buy a program for the «cloud» once. More often than not, a program for using on the Internet cost is lower than its price for personal computers analogies. Those users only are going to use the program, who need it. Moreover, expenses on its support in good operating condition will be brought to nought at all.
6. Automatic program upgrading
At any moment, when a user launches a remote program s/he needs, s/he is going to be sure about safety. The programs will always be upgraded to the latest version – with no need for checking or following the updates.
7. Computation power increase
If a personal computer capacity is always limited to its own, now it is unnecessary to have a high-power computer for difficult tasks computing. Users can launch the most difficult tasks because they process on the «cloud». In point of fact, users can work with a supercomputer without any special purchase easily and cheap.
8. A plenitude of stored data
While storing data on a server, users may forget about hard disks limitations. The «cloud» is very flexible and automatically conform to the needs of a user. Usually available the volumes of the cloud services are calculated by millions of gigabits of data free space.
9. Compatibility with any operation system
An operating system does not play any role for the «cloud». Mac, Windows or UNIX users may freely exchange documents between each other. Access to programs goes through web-browsers, which equally installed into any operating system.
10. Compatibility of document formats
If users use one cloud program for record keeping, they will never have incompatible documents and files. It is simply impossible. The most vivid example is Google Docs, which allows many people to keep documentation at the same time. Everything that is required is any computer with a web-browser.
11. Simplification of teamwork for a group of people
There is no need to constantly send each other new versions of documents while working with the cloud; they are always available in the latest version. Moreover, any change, a person makes, is seen by the entire team working upon the document at once.
12. Anytime access to documents
No one in the company will be able to forget the necessary files or folders. Be at home, at work or on vacation, if there is an internet, documents are there just as well.
Users have an opportunity to connect not from a computer only but also from any other device having a browser – a phone, a smartphone, a tablet or a laptop.
14. Data loss prevention (or physical data storage steal)
If you sent the data to the «cloud», it will save them automatically and send copies to the reserve servers, which can be located in different countries and continents.
# Cloud Storage Cons
1. A constant access to the Internet is required.
Cloud-based servers require an Internet connection. If there is no connection, one can work with the documents, which were uploaded to the local computer. If the access is gone, programs, documents, and files are gone too.
2. The fast and fine Internet is required.
If you use the old generation Internet, you might need to change it. A good-working, fast and fine Internet is required for work with clouds. However, within the context of the everyday world, this is a low hanging fruit for every person for a hardy fair price.
3. Cloudy programs may work slowly.
Some operations connected with high-cube of information transmission may be done slower than as if they were done by means of a program installed on a personal computer. In addition, slow Internet or server overflow through which a data transfer is going can make speed slower.
4. Far from every program is available for remote access
For example, Microsoft Excel is much more functional than its analogue in Google Docs.
5. Your data security can be at risk
Not only «can». If your cloud encodes data well and makes constant reserve copies, there should be no difficulties.
6. If you lost data on the cloud, you lost them forever
It is a fact. No exceptions. Luckily, it is quite difficult to lose data on the cloud and far from everyone is able to do so even if s/he wants to.
Despite the fact that there are more pros than cons, each chooses what is the most effective for his/her task. A desire of the data owners to secure their information data has grown into a reserve copying, which has become compulsory as long as the imperfection of technologies kept on their toes. Later on, technologies have become perfect and users began to forget their old fears and safety measures. Certainly, today a data carrier reliability has grown significantly, but at the same time, data size increased gigantically, meaning that a price of a damage or a loss of such a carrier too. This article does not suggest making reserve copies of critical data.
Importance of reserve copying
1. There should always be a backup
whatever technologies develop, good-old reserve copy will never lose its value, save frustration at hard times, work let alone depressants. It, if anything crops up, allows us to stay calm, act thoughtfully, allowing a reasonable risk.
If all the components are duplicate on your server and data is kept on an expensive massive with redundancy, flap a false feeling of safety away from you. Nobody is perfect. Logic bugs and human factor do happen.
2. Backup should be automatic
Automated backup only done as scheduled gives an opportunity to renew a relatively on the front burner data, for example, yesterday`s, but not March`s. backup has to be done also before any potentially dangerous operations, be it a modernization of equipment, microcode renewal, patch installation, data migration.
3. Backup renewal is a last-ditch method
Fall back on renewal when there are no other chances. Which is why it is always slow and it is always a hurry and stressful.
re-new always to a reference position on a disc so you did not have to re-record original data, but somewhere nearby, so there was a chance to check, what you renewed as a result.
4. Backup has to be saved separately from data and 2 weeks as a minimum
It is a suggested time, so even a «dilatory accountant» managed to get its act together that something is lost or damaged. You can save for more time if space allows.
5. Backup requires regular checking
The main disadvantages of a feed are sequential access and relatively low storage reliability. There is no way to find out whether a backup is to be restored from a feed without errors while you check it on practice. In-memory stores, unlike feed, are protected from demagnetizing and, in general, are more predictable. Nevertheless, a regular checking of any backup allows sleeping easily.
6. It is useful to duplicate backup to a remote site
Technogenic catastrophes, power cut in an entire city and other troubles could take business anywhere. Which is why a remote site is a good practice where, one way or another, reserve copies get into trouble.
7. Backup is a stress for the working system
A main system production downfall might happen during copying. This is why making reserve copies are always planned for the period of minimal activity. However, the number of systems grows, which operate requests twenty-four-hour.
8. Data can be also copied on SAN, but not on LAN only.
A big flow of copied data overloads the net. There is a technique, which is called LAN-free backup. If data storage system (DSS) with data and libraries are connected in SAN (storage network), it is quite reasonable to transfer data between DSS and a library directly through SAN, at that excluding a local area network loading. Oftentimes, it happens faster, because far from everywhere a local area network is built on 10G, and ordinary 1GB ethernet is second to carrying capacity even not the cutting edge SAN.
