What are the Types of Cloud Computing and Cloud Services

 In Business, Education

The cloud computing market has been rapidly expanding, especially in the last couple of years. Despite the dramatic increase in cloud adoption some users still get lost in the dizzying array of cloud-related terms. In this article we are turning back to the basics and explain about the types of cloud computing, cloud services, and the benefits of cloud computing without getting too technical. So, let’s begin with the fundamentals on the types of cloud computing.

Fundamentals of the Cloud.

In contrast to its natural prototype, the digital version of clouds is based on physical and virtual infrastructure. All of the provider’s data and services are stored on a very solid, dependable network of infrastructure known as the cloud. Customers can access these server-based cloud networks via the Internet, along with their resources, which include data storage, streaming content online, and infrastructure services like Google Cloud, AWS, or Azure.

Types of Cloud Services

There are three main cloud services that are provided to customers online and hosted by independent providers: IaaS, PaaS and Saas.

IaaS

IaaS stands for the Infrastructure as a Service. IaaS stands for the Infrastructure as a Service. The entire infrastructure is managed by the cloud service provider (e.g., data storage, the actual servers, network, virtualization). The customer gains access with a dashboard or API. So, the user handles the OS, applications, and middleware, and the provider deals with the hardware (e.g., hardware, networking, hard drives, data storage, and servers), and takes care of hardware issues, outages, and repairs.

PaaS

This acronym is short for Platform as a Service. While the user deals with the apps that run on top of the platform and any necessary data, the external cloud provider offers and manages hardware and an application software platform. Programmers and DevOps experts prefer this arrangement because it spares them from creating and maintaining the required infrastructure.

SaaS

SaaS means Software as a Service. SaaS means Software as a Service. Even if we are unaware of it, the majority of us use SaaS almost every day. Web applications

and mobile apps that are offered and managed by the cloud service provider are known as SaaS and are accessed through a web browser. Software updates, bug fixes, and maintenance are the user’s responsibility. SaaS examples include Dropbox, ZenDesk, HubSpot, Slack, Salesforce, cloud-based Microsoft Office 365, and Adobe Creative Cloud. SaaS offers a significant advantage because it eliminates the need for each user to directly load the software onto their computer.

Types of Cloud Computing

There are four primary types of Cloud Computing:

Public Clouds, which is a virtual environment partitioned and redistributed to many customers, often referred to as “tenants.” These clouds are usually created from IT infrastructures that the customers don’t own. Amazon Web Services (AWS), Google Cloud, Microsoft Azure, Alibaba, and IBM are popular examples of public cloud computing. Even though public clouds are typically operated off-site, some cloud service providers have started to provide customers with cloud services that are housed in the on-site datacenters of their clients.

Private Clouds, which are cloud environments exclusively dedicated to a single group, entity, or user set behind the customer’s firewall. A cloud is automatically categorized as a private cloud if it is located in a private IT infrastructure that is separate from the general public. Offerings for private clouds come from HPE, VMWare, IBM/Red Hat, and OVHcloud. These days, private clouds aren’t just for on-site IT infrastructures. On rented, vendor-owned, off-site data centers, clients can create private clouds.

Hybrid Clouds, which are a single IT environment consisting of multiple settings linked together via application programming interfaces (APIs), virtual private networks (VPNs), local area networks (LANs), and/or wide area networks (WANs). However, there isn’t a single accepted “hybrid” definition. Hybrid cloud can link two or more private clouds, two or more public clouds, at least one private cloud and public cloud.

Multi-Clouds

Multi-clouds are made up of more than one cloud service taken from more than one cloud vendor, public or private. All hybrid clouds are multi-clouds, but not all multi-clouds are hybrid. However, when multiple clouds are linked together or integrated using tools from a third party, multi-clouds turn into hybrid clouds. It involves patching together various SaaS, Iaas, PaaS, and other services from multiple providers or internal IT to fit current business objectives.

To sum up, let’s overview some of the most frequently asked questions about the Cloud:

1. Is the cloud secure?

There is always a chance of a cyberattack because the cloud has access to the Internet. However, providers take care of their business reputation and have proper security measures in place.

2. What is the value of Cloud market?

In 2020, the cloud market was valued at around $371 billion, experts believe it will reach an astounding $832 billion.

3. What’s the largest cloud service provider?

TOP-3 players on the Cloud market are Amazon Web Services (AWS), followed by Microsoft Azure and Google Cloud.

4. What’s the largest SaaS company in the United States?

Salesforce, with a market capitalization of more than $200 billion, is still the market leader, but Zoom, the video conferencing service, has gained a lot of attention due to its skyrocketing market value of over $90 billion as a result of COVID pandemic.

5. Which cloud service suits me the best?

There is no correct response; it all depends on your company’s needs. Choose a public cloud if your workloads are high volume and your needs are constantly changing. However, choose a private cloud option if your workloads are more stable. This is just one typical illustration. In order to develop a cloud strategy, each company must assess its requirements and available options.
