Welcome to the Cloud Computing Series. In this Series we do not learn about how to use a specific Cloud, but we will learn about the technology underlying Cloud. This series I refer to from the book Cloud Computing For Dummies .
Cloud is a term that you have heard a lot in recent years, it has completely changed the way businesses operate and deploy software. So what is Cloud? Before understanding what Cloud is, we need to understand the concept of Cloud Computing.
Cloud Computing
Cloud Computing is a method of providing computing resources to users in the easiest way, including applications, software, hardware, storage drives, network connections, …
With Cloud Computing, everything from infrastructure to applications can be provided to users as a service over the Internet.
Cloud
Cloud is a collection of many computing resources from hardware, networks, storage drives, and software applications located at distributed servers around the world, and these servers all use Cloud Computing technology. so that users only need an Internet connection, they can easily access any resource.
And Cloud will be deployed with different models.
Types of Cloud Models
Cloud has two main types of models: Public Cloud and Private Cloud.
And from these two models, we will have two more sub-models: Hybrid Cloud and Multi-cloud.
Hybrid Cloud is a hybrid environment between Public Cloud and Private Cloud plus Data Centers.
Multi-cloud is an environment that combines many Public Clouds.
Public Cloud
Public Cloud is a Cloud model whose resources can be used by anyone. Public Cloud is the most popular model today because in addition to providing computer resources, Public Cloud also provides a lot of accompanying services and applications, helping businesses’ software deployments become more and more popular. faster.
An example of Public Cloud is AWS, with AWS, the deployment of our application is very fast, the specific case is when we need the Redis application, we do not need to install anything, AWS provides us with the service. Elasticache and just a few simple steps we have Redis to use.
Most Public Cloud developers provide users with Web Console tools and APIs so that users can easily access Cloud resources.
Private Cloud
Private Cloud is a Cloud model whose resources are allocated exclusively to businesses or their employees and partners. Private Cloud is an environment that requires high security, so it is often placed in a firewall and not everyone can access it. Private Cloud is usually developed and managed directly by the business that uses it.
We can simply understand that Private Cloud is an enterprise’s own Data Center that uses Cloud Computing technology.
An example of Private Cloud is FPT Cloud, FPT develops Cloud for personal use by businesses and employees.
It is not easy for businesses to develop their own Cloud environment, but now that problem has been partially solved.
Use Public Cloud on Data Center
Today, Public Cloud developers package their Cloud services into applications that can be installed on an enterprise’s Data Center (On-premises) environment.
With this, businesses can use Public Cloud services easily and still ensure security, because data and applications are run on their Data Center.
Conclusion
So we have learned about the concept of Cloud Computing and Cloud. Cloud will be the future of the technology industry and we should learn to not be outdated, I suggest you learn AWS because this is the most popular Cloud at the moment. The next article we will learn about the concept of Resource Pools and Cloud Models.
