What is cloud computing? How does cloud computing work?
When it comes to offering hosted services via the internet, cloud computing is an umbrella word. Infrastructure as a service, platform as a service, and software as a service are the three primary forms of cloud computing services (SaaS).
What is cloud computing?
IT resources may be delivered via the Internet for a fixed price, and the user only pays for what they consume. Instead of purchasing, maintaining, and operating your own data centers and servers, you may instead use a cloud service like Amazon Web Services to obtain computing power, storage, and databases on an as-needed basis (AWS).
How does cloud computing work?
We may break down a cloud system’s front and rear end into the front and back parts. The system’s rear end is referred to as “the cloud.”
Computers and networks belonging to the customer make up the front end. The cloud system’s application is also crucial. All cloud computing platforms are not required to have the same user interface.
Various computers, servers, and data storage systems make up the cloud on the back end of the cloud technology system. From data processing to video games, the cloud computing system can encompass any kind of computer software. In addition, a dedicated server is often assigned to each application.
Types of cloud computing
You may use private, public, hybrid, and multi-cloud computing. Aside from that, there are three primary forms of cloud computing: There are three main types of cloud computing services: infrastructure, platform, and software (SaaS).
1. Public Cloud
The term “public cloud” refers to a cloud environment not owned by the end-user. For example, Alibaba Cloud, Amazon Web Services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure are major public cloud providers.
Today’s public cloud providers are starting to provide cloud services in their customers’ on-premise data centers, departing from the traditional model of off-premises cloud computing. As a result, local and ownership differences are now meaningless.
When a system’s resources are divided up and made available to various users, it becomes a public cloud. Public cloud providers no longer need fee structures since some (such as the Massachusetts Open Cloud) enable users to access their clouds for free. Public cloud providers’ bare-metal IT infrastructure may be abstracted and resold as IaaS or built into a cloud platform and resold as PaaS.
2. Private Clouds
The term “private cloud” refers to a kind of cloud computing system in which only a single end-user or group has access to the resources provided by the cloud. For a cloud to be considered private, the underlying IT infrastructure must be devoted to a single client and accessible only to them.
Cloud computing resources for private clouds don’t have to come from on-premises IT infrastructure anymore. With the advent of off-premises cloud infrastructure built on leased, vendor-owned data centers, traditional data center location, and ownership regulations are being rendered moot. Several private cloud subtypes have also emerged, including:
a. Managed Clouds
Private cloud services are provided by a third-party provider that is installed, configured, and maintained on behalf of the customer. Enterprises with understaffed or inexperienced IT departments may benefit from managed private clouds, which provide a superior personal cloud service and infrastructure.
b. Dedicated clouds
An accounting department, for example, may have its private cloud inside the company’s private cloud department.
3. Hybrid Clouds
Local area networks (LANs), wide area networks (WANs), virtual private networks (VPNs), and APIs integrate disparate IT systems to form a single, apparently seamless hybrid cloud.
Depending on who you ask, the properties of hybrid clouds might vary widely. For instance, a hybrid cloud may need the following:
● Minimum of 1 private cloud along with 1 public cloud
● 2 or more private clouds
● 2 or more public clouds
Connected to at least one public or private cloud, whether it is physical or virtual, A hybrid cloud is one in which applications may travel between different but interconnected environments inside an IT system. You must use consolidated IT resources for at least some of these settings. A single management and orchestration platform is needed to handle these settings.
4. Multiclouds
Multicloud is a cloud strategy that utilizes more than one public or private cloud service from several cloud vendors. However, not all hybrid clouds are multi-clouds and vice versa. Instead, integration or orchestration links various clouds together, turning them into hybrids.
By design or by accident, a multi-cloud environment may exist (either so that sensitive data may be better protected or so that you can use redundant storage space for greater disaster recovery) (usually the result of shadow IT). Multiple clouds are becoming increasingly frequent in organizations looking to enhance security and performance by using a diverse set of infrastructures.
