Cloud computing is a method of delivering various services over the internet. The resources in question are, for example, applications such as data storage, servers, databases, networks, and software.
Instead of storing multiple files on your hard drive or local storage of your computer or mobile phone, cloud-based storage allows you to store files as long as you have access to the internet.
Cloud computing is a popular option because it has many advantages, such as reducing costs, and increasing productivity, speed, efficiency, performance, and security. So, it’s no wonder many companies or people use the Cloud to store data.
This time, Indonesian Cloud will share with clouders what Cloud computing is.
Futher about cloud computing
It is called cloud computing because the information is accessed remotely in the “cloud” or virtual space. Companies that provide cloud services allow their users to store files and applications from remote servers. They can also access it as long as there is an internet connection.
Cloud computing can be public or private. Public Cloud provides its services publicly on the internet. Meanwhile, on the other hand, private clouds only offer their services to certain people. There is also a hybrid option, which combines both public and private clouds.
Examples of using cloud computing
Apart from its various services, cloud computing provides its users with a series of functions, such as:
- Email is an example of the Zimbra Mail service
- Storage, backup, data retrieval
- Build and test applications
- Analyze data
- Streaming audio and video
Cloud computing is a relatively new service, but it has been used by various companies ranging from small to large corporations, companies or government ministries, and even individual users.
Not only that, but cloud computing also has services such as language processing, artificial intelligence, and standard programs at work. Anyway, services that do not require you to be physically in front of hardware such as computers and laptops.
Cloud Computing Services
Cloud computing is different from conventional servers, which force companies to spend large sums of money to buy servers, and routers and employ human resources to maintain storage and infrastructure. Some examples of types of cloud computing services are:
Public cloud: Use of a type of cloud computing intended purely for the public.
Private cloud: This service provides infrastructure management and operation only for specific clients who are usually large-scale and have the funds to have their cloud;
Community cloud: Used jointly by several organizations that have the same interests and need the same level of security;
Hybrid cloud: Even though it is an independent entity, it uses technology that enables data portability and inter-cloud application connectivity.
Cloud Computing Types
Cloud computing is not a technology like a microchip or a mobile phone. Instead, it is a system primarily composed of three services: software-as-a-service (SaaS), infrastructure-as-a-service (IaaS), and platform-as-a-service (PaaS).
1. Software-as-a-Service (SaaS)
As the name suggests, SaaS is a cloud computing service that provides ready-to-use applications. SaaS users do not need to install applications on their devices. In addition, users only bother with updates if the service provider’s developers do it.
One example of SaaS is Office 365, which offers Microsoft Office applications that can be accessed via a browser.
Imagine using Microsoft Word, but your account automatically saves the document. These documents can be accessed on any device as long as you log into your account.
2. Infrastructure-as-a-Service (IaaS)
Unlike SaaS, which is a ready-to-use application, IaaS is a series of computing resources or servers.
IaaS servers are available in different specifications, so users can choose the one that suits their needs. Generally, users are also allowed to select the operating system and type of virtualization for their server. Practical, huh?
With IaaS, users can create their servers. It is expensive and troublesome, especially when users need to add server resources.
Because of the flexibility and resources that IaaS offers, these services are generally aimed at enterprises. Examples of these service providers are Amazon Web Services and Microsoft Azure.
3.Platform-as-a-Service (PaaS)
This type of cloud computing provides a platform for developers to create and test applications online. Platform operating systems and resources are managed by the provider, so developers don’t have to worry about devices for their work.
With PaaS services, building and testing applications are more straightforward because developers must have several computing devices with different operating systems.
Some examples of PaaS services often used are Google App Engine and Oracle Cloud Platform.
Benefits of Using Cloud Computing
Cloud computing is about more than just being able to access files remotely. Thanks to cloud computing, users can check email on any computer or even store and access files from anywhere, such as Dropbox or Google Drive.
Thus, companies using the cloud can cut costs significantly. Before the cloud, companies had to buy, own, and build their management information technology (IT).
Conversely, with the cloud, companies only need a central server and IT division to ensure that their internet is fast and stable so that their employees can interact with the cloud online.
1. Save cost, space, and time
The costs you incur to create and manage the infrastructure are pretty expensive. Not to mention, you have to provide adequate space for the devices you use.
If you use cloud computing, you can save costs, space and time.
In terms of costs, for example, instead of having to buy all the infrastructure components, you have to pay a much cheaper monthly fee. Not to mention, you have to have someone specifically in charge of managing these components so they can work optimally.
Plus, you can set up a place to build your infrastructure if you use cloud computing. It is because the service provider manages the infrastructure.
Building and managing computing infrastructure also requires a lot of time; moreover, if you need a better experience.
2. Easy Scaleability
As your business grows, the data you use will increase, for example, customer accounts and transaction data. That way, your computing capacity must also be increased.
If using your infrastructure, you have to add or replace components. It was not only inconvenient but also expensive.
It’s different if you use cloud computing services. Scalability is more effortless because you can upgrade the service according to your needs. For example, you can increase your storage capacity or upgrade to a faster service.
3. Easy To Collaborate
Because you live online, cloud computing services allow you to work from anywhere. These benefits are even more pronounced if you work in a team. Each team member does not need to be in one place to collaborate.
4. Easy To Backup Data
Most cloud computing services are equipped with an automatic backup feature. With this, you don’t have to remind yourself or your team members to do the task. Backed-up data is always available for you to use.
