The article introduces the basic concept and cloud computing training for beginners to help you learn cloud computing more comprehensive.
What is cloud computing?
Cloud computing can be defined as providing computing power (CPU, RAM, network speed, Storage OS software) services through the network (usually on the Internet), rather than actually having computing resources at the customer's location.
Why should I name the cloud?
The term "cloud" comes from network design, and network engineers use it to refer to various network devices and their interconnected locations. The shape of this network design is like a cloud.
Why choose cloud computing?
With the increase of computers and mobile users, data storage has become a priority in all areas. Today, large enterprises and small businesses are relying on their own data to flourish, and they spend a lot of money to maintain this data. It requires a strong IT support and storage center. Not all enterprises can afford the high cost of internal IT infrastructure and backup support services. For them, cloud computing is a cheaper solution. Perhaps its efficiency in storing data, computing and reducing maintenance costs has also successfully attracted larger enterprises.
Cloud computing reduces the hardware and software requirements of users. The only thing the user must be able to run is the cloud computing system interface software, which can be as simple as a web browser, and the cloud network will take care of the rest. We have all experienced cloud computing at some point. Some popular cloud services that we have used or are still using are mail services such as gmail, hotmail, or yahoo.
When accessing email services, our data is stored on cloud servers, not on our computers. The technology and infrastructure behind the cloud are invisible. Cloud services are based on user-friendliness and functionality, so whether it is based on HTTP, XML, Ruby, PHP, or other specific technologies is less important. Individual users can connect to cloud systems from their own devices (such as desktops, laptops, or mobile devices).
Cloud computing effectively uses small businesses with limited resources. It enables small businesses to access previously unavailable technologies. Cloud computing can help small businesses turn maintenance costs into profits. Let's see how?
In the internal IT server, you must pay special attention to ensure that there are no defects in the system, so that the system runs smoothly. If there is any technical failure, you will be fully responsible; it will require a lot of attention, time and money to repair. In cloud computing, service providers will take full responsibility for complexity and technical failures.
Benefits of cloud computing
The potential for cost savings is the main reason why many organizations adopt cloud services.
Cloud computing allows you to use services freely according to your needs, and only pay for the services you use. Thanks to cloud computing, IT operations can be run as an outsourcing department without a lot of internal resources.
The following are the benefits of cloud computing:
Reduce users' IT infrastructure and computer costs
Performance improvement
Less maintenance issues
Instant software updates
Improved compatibility between operating systems
Backup and restore
Performance and scalability
Increased storage capacity
Improve data security
Types of clouds
You can subscribe to four different cloud models based on business needs:
Private cloud: Here, computing resources are deployed for a specific organization. This method is more used for intra-enterprise interaction. A place where computing resources can be owned and operated by the same organization.
Community Cloud: Here, computing resources are provided for communities and organizations.
Public cloud: This type of cloud is commonly used for B2C (business-to-consumer) type of interaction. Here, computing resources are owned, managed, and operated by governments, academic institutions, or commercial organizations.
Hybrid cloud: This type of cloud can be used for two types of interactions-B2B (business-to-business) or B2C (business-to-consumer). This deployment method is called a hybrid cloud because computing resources are bound together by different clouds.
Cloud computing service
The three main cloud computing products are
Software as a service (SaaS)
Platform as a service (PaaS)
Infrastructure as a service (IaaS)
Different companies use some or all of them according to their requirements.
SaaS (Software as a Service)
SaaS or software as a service is a software distribution model in which applications are hosted by vendors or service providers and provided to customers through the network (Internet). As a basic technology to support service-oriented architecture (SOA) or Web services, SaaS is becoming an increasingly popular delivery model. Through the Internet, the service can be used by users anywhere in the world.

Traditionally, you need to purchase a software application and then install it on your computer. On the other hand, SaaS users usually purchase monthly via the Internet instead of purchasing software to subscribe.
Anyone who needs access to specific software can subscribe as a user, whether it's one or two people, or every thousand employees in the company. SaaS is compatible with all Internet-enabled devices.
You can use SaaS to perform many important tasks, such as accounting, sales, invoicing, and planning.
PaaS (Platform as a Service)
Platform as a service, called PaaS, provides a platform and environment that allows developers to build applications and services. The service is hosted in the cloud, and users can access it through the Internet.
For a simple understanding, let's compare it with the drawing pictures, your school teacher will provide you with drawing colors, different brushes and paper, and you only need to use these tools to draw beautiful pictures.

The PaaS service is constantly updated and new functions are added. Software developers, web developers and enterprises can benefit from PaaS. It provides a platform to support application development. It includes software support and management services, storage, networking, deployment, testing, collaboration, hosting and maintenance of applications.
IaaS (Infrastructure as a Service)
IaaS (Infrastructure as a Service) is one of the basic service models of cloud computing along with PaaS (Platform as a Service). It provides access to computing resources in the "cloud" of the virtual environment on the Internet. It provides computing infrastructure, such as virtual server space, network connections, bandwidth, load balancers, and IP addresses. The hardware resource pool is extracted from multiple servers and networks that are usually distributed in multiple data centers. This provides redundancy and reliability for IaaS.
Cloud computing for beginners
IaaS (Infrastructure as a Service) is a complete software package for computing. For small businesses that are seeking to reduce the cost of IT infrastructure, IaaS is one of the solutions. Every year, a lot of money is spent on maintaining and purchasing new components, such as hard drives, network connections, external storage devices, etc., and business owners can save other costs by using IaaS.
