Description: Cloud services appear everywhere, from the reports of technology companies to the box of a new phone. You should learn more about its impact on the future of the world.
According to IBM, cloud computing, or cloud services, is the provision of computing resources to the user according to the purpose of the village using the Internet connection. That resource could be anything related to computing, such as software, hardware, and network infrastructure, to servers and large server networks.
Before the cloud service comes, you have to do everything yourself. As an individual user, if you want to save data, you have to buy a hard drive by yourself. Do you want to back up your data regularly and immediately? In addition to the hard drive you have to find the software itself, connect it to the network if you want. If you want to make a website, you have to buy the server yourself and install it. If you want to manage your home store sales, you have to buy your own accounting software or sales software and install it on your home computer. The money you spend is followed by you later, called “maintenance” money. You install the server, you have to maintain it yourself, equipped with the cooling system and backup…
These problems seem simple, but in essence, it costs you a lot of effort and money. For businesses, the cost of “maintenance” is also great because they not only use small software such as Word, Excel, and PowerPoint but giant and complex management systems, with continuous data input and output. Therefore, a malfunction can also cost millions of dollars in sales, or production delays. They have to maintain a team of employees to install, configure, test, run, secure and update their systems.Then Cloud service comes out; it helps you manage your hardware and software. You need to save the data; there are OneDrive, Dropbox, and Google Drive for you. You do not need to care about your files are stored on the HDD, if it is broken or not, there is need to back up to the secondary HDD or not, where it is located. Everything has been taken care of by the cloud service provider, and in this case, it is Dropbox, Google or Microsoft. If the HDD fails, they will replace themselves, they will do the backup routine periodically, you do not have to worry.
Another example: phone contacts. In the past, you had to back up your contacts periodically to your computer, keep the contacts files, and then if you change your phone, it would take time to reset your contacts. Now there’s Google, there’s Apple, there’s Microsoft or BlackBerry to take care of your contacts. Each time you add a new number; the contacts will be synchronized to “cloud service” and contained there. In case you switch to another phone, the contacts can be downloaded quickly. No more regular backups, no need to manually copy files.

The effect of cloud services
The biggest benefit of cloud computing is the cost savings
Mainly you will reduce the cost of initial infrastructure investment, the cost of purchasing hardware, software and maintenance, costs for installation, server placement and day-to-day operation, costs of hiring care and much more.
Convenience of cloud service
You can quickly use something without complicated installation. You can quickly access them anytime, anywhere, and almost without being dependent on software or hardware. If you are using a traditional storage drive but forget it at home, how can you get the data? While using Dropbox, just go to its website and download the necessary file. Or like Gmail, you can quickly borrow your friends’ laptops to check mail without having to set up a messenger in Outlook, even no need Outlook.
Safety and continuity of cloud service
When your HDD is damaged, you will lose data. Meanwhile, your data that is on Dropbox, OneDrive will be more secure. If your hard drive is damaged then your back up data will be maintained continuously and you can continue to use it as usual.
The security of cloud service
If you lose a laptop containing sensitive data, the damage will be huge. If you save that stuff uploaded to the cloud service, you lose just one piece of hardware; the data is safe in your online account.
Cloud services have 3 major types
Infrastructure as a Service (IaaS):
According to Amazon, it is the most basic level of cloud service. IaaS will sell you the network, the computer (the virtual machine or the machine depending on the needs), as well as the data storage. More specifically, you can rent a “cloud server” with the CPU, RAM, hard drive (SSD or HDD) as needed. So you have a server, what server to put in the data center, what network of telecommunications services you use… then you don’t need to mind any of those again.
Platform as a Service (PaaS):
PaaS helps you bypass the complexity or hassle of managing your own infrastructure. If you hire a PaaS service, just focus on deploying your software on it and start running. Thanks to PaaS, you do not have to worry about updating Windows to your server every time you patch, do not have to manage your RAM, CPU, do not have to plan for resources…
Software as a Service (SaaS):
This is the highest level of the cloud service classification scheme. It is a complete product that is operated and managed by a supplier. In most cases, people use SaaS to talk about software, applications that can be used immediately by the end users.
3 cloud service types
In all three types of cloud services, the most “instant noodles” type is SaaS. So that kind of approach is very easy to reach end users because they do not have to know much about computer technology to use it. SaaS also attract customers, by offering lots of free services. Dropbox, Gmail still has free stuff. Of course, SaaS users will have no control over the underlying infrastructure.
In addition to the advantages, cloud services are still defective. However, the benefits that it brings have crushed the restrictions so everyone still accept to get more benefits. So cloud service is growing, and that trend does not seem to stop short in the future.
