Cloud Computing – Cloud computing is a method of delivering various services over the internet. These resources include data storage applications, servers, networks, databases, and software.
With cloud computing You can store data in cloud storage without having to worry about storing data on your computer at risk of file damage.
Cloud computing is the most popular alternative with many advantages such as increased productivity, cost-effectiveness, efficiency, performance, speed, and better security.
We can see that many companies have started to implement cloud computing for data storage.
Understanding Cloud Computing
From the name alone cloud computing where all information can be accessed by remote methods online or virtual space.
Cloud service providers provide services for those of you who want to store data and applications from remote servers.
Which only requires an internet connection which means the user does not need to be in a certain place where to get access to the files.
Cloud computing which is public or private. As you know that public cloud provides its services publicly from the internet. While the private cloud only provides services to certain people. And also for the hybrid option, which combines both a public cloud and a private cloud.
Examples of Utilizing Cloud Computing
This service has many benefits for its users which you can see below:
- Provides email functionality like Zimbra Mail.
- Storage, Backup and retrieval of data.
- Create and test applications.
- Data analysis.
- Streaming audio and video.
Cloud computing is a relatively new service, but has been used by various companies from SMEs to large companies. Companies or government ministries, even individual users.
The cloud has services such as language processing, artificial intelligence, as well as standard on-the-job programs. So that users do not need to be physically present to be in front of hardware such as computers or laptops.
How Cloud Computing Works
Each type of cloud computing has the same two factors in general, namely the data center that is outside and must have internet to access it. Resources on servers in the data center that can be gathered into a large unit to be ready to accommodate virtual services.
These pooled resources can be organized to be more flexible, so that users can access more storage space when needed. However, when the resource is not being used, it will be released back to the cloud if it is no longer needed.
Resource requirements on servers are typically on-demand which offers virtually unlimited scalability and flexibility. This is because you will always be changing or dynamic.
Advantages of Using Cloud Computing
Cloud computing if not just being able to access data remotely. But thanks to this service, users can check email from anywhere, even you can save data from anywhere like Google Drive.
But companies typically using the cloud can cut costs quite significantly. Before the cloud, companies had to buy, build and manage their own IT technology information.
On the other hand, if there is a cloud, the company only needs a central server and IT division to ensure the internet is fast and stable, so that workers can work better online.
With the cloud, workers or employees can save storage space on computers or laptops. When a software or program needs updating, you can just download it conventionally as well as using a hard drive.
As an example of the Microsoft Office 365 application that you can now use directly without the need to install it on your computer or laptop. You just create a browser and use it online with a subscription method.
Cloud Computing Services
Cloud computing is a service or system consisting of three services, namely: software-as-a-service (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS).
SaaS (Software as a Service)
By involving the application license on the user. So this license is usually granted through a pay-as-you-go or on-demand method. Types like this one can be found in Microsoft Office’s 365
PaaS (Platform as a Service)
is said to be the most complex. PaaS is almost the same as SaaS, but the biggest difference is that, instead of sending software via online, PaaS is indeed a platform for producing software delivered over the internet. Examples come from PaaS such as Salesforce.com and Heroku.
IaaS (Infrastructure as a Service)
involves a method for delivering a file from the operating system to the server and storage, via IP-based connectivity as part of an on-demand service. Clients don’t have to buy software or servers. Well-known examples of this type are Public Cloud from Indonesian Cloud and Microsoft Azure.
Those are some explanations from Netdatastarting from the benefits to the usability that you can get if you use Cloud Computing services.
