What is an example of a public cloud? Definition, 5 types, and advantages

In this article, we will discuss an example of a public cloud and what the advantages and disadvantages of public clouds in cloud computing are. But first of all, let’s discuss the definition of public clouds and their uses.

What is a public cloud?

example of a public cloud

The public cloud is defined as the availability of computing services by third-party providers. Public clouds make IT resources such as compute, storage, development platforms, and applications available as services over the Internet. Services on the public cloud are available to anyone who wants to use or purchase them. Public clouds are operated by cloud service providers that deliver services over the Internet. Public clouds offer the scalability and flexibility to efficiently meet the collaboration needs of today’s global workforce and deliver significant business value to enterprises. With public clouds, cloud service providers are responsible for managing the systems, allowing businesses to reduce the cost of purchasing, managing, and maintaining on-premises infrastructure. It also offers scalable RAM and flexible bandwidth, allowing businesses to easily grow with their storage needs. In short, public clouds are cost-effective, scalable, accessible from anywhere, and offer automated data backup.

What is public cloud storage?

Public cloud computing is the availability of computing services by third-party providers. Public clouds make IT resources such as compute, storage, development platforms, and applications available as services over the Internet. Public cloud services are available to anyone who wants to use or purchase them.

The public cloud refers to computing services provided over the Internet by third-party providers. Unlike private cloud services, public cloud services are available to anyone who wants to use or purchase them. These services can be free or sold on demand. When sold on demand, users have to pay for the CPU cycles, storage, or bandwidth consumed on a per-use basis.

Public clouds are operated by cloud service providers that deliver services over the Internet. Public clouds provide the scalability and flexibility to efficiently meet the collaboration needs of today’s global workforce and deliver significant business value to enterprises.

Public clouds help businesses save on the cost of purchasing, managing, and maintaining on-premises infrastructure because the cloud service provider is responsible for managing the system. It also offers scalable RAM and flexible bandwidth, allowing businesses to easily expand their storage needs. In short, public clouds are cost-effective, scalable, universally accessible, and offer automated data backups.

Public clouds make IT resources such as compute, storage, development platforms, and applications available as services over the Internet. These services are available on-demand through our self-service portal. With a pay-as-you-go model, public clouds are flexible, scalable, and can be accessed by multiple customers simultaneously. This is called multi-tenancy. Public clouds are usually managed in data centers belonging to service providers. This shared model of public clouds significantly reduces costs for customers.

How Public Cloud Works

Every public cloud has certain features. These features include:

  • Multi-tenant architecture: This means that multiple users (or tenants) leverage shared infrastructure (such as compute resources) to run their workloads. Each tenant’s data is isolated and remains separate from other tenants’ data.
  • Scalability: Provides on-demand IT resources on a self-service provisioning basis over the public internet or dedicated networks.
  • Flexibility: Public cloud resources are flexible and available on a pay-as-you-go basis.
  • High availability: Public cloud hosting providers typically offer a 99.99% SLA uptime guarantee. Data security: customer data is stored with high security on the public cloud. Security features and tools included by cloud providers include DDoS protection, anti-malware protection, and cloud firewalls.

Why the public cloud?

Gone are the days when, if you needed IT resources, you had to configure everything yourself.

Now you can rent the computing power you need, including advanced AI services, developer tools, and GPUs to support virtually any workload.

All are available in the public cloud and are maintained and updated by cloud service providers. You can pay a monthly fee to leverage as many or as few resources as you need.

Public cloud models operate on OPEX, allowing startups to achieve global scale without CAPEX.

Not surprisingly, Gartner predicted that the public cloud services market will grow 17.5% to $213.4 billion in 2019, up from $182.4 billion in 2018.

Gartner forecasts that global public cloud end-user spending will grow by 23% to $332.3 billion in 2021, up from $270 billion in 2020.

Gartner’s latest forecast predicts that global public cloud end-user spending will reach nearly $500 billion in 2022, up from $411 billion in 2021. And by 2023, public cloud end-user spending is expected to reach nearly $600 billion.

Advantages of Public Cloud

Organizations are moving to the cloud for flexibility and other business benefits.

Here are some of the benefits of the public cloud.

  • Cost savings: Moving your organization’s IT operations and workloads to the public cloud can save you a lot of money. Cheaper than a private cloud. Because cloud service providers allow you to make the most of your computing servers, storage, and other hardware,. The multi-tenant architecture ensures that the public cloud infrastructure is used as efficiently as possible.
  • Latest technology: cloud solution providers offer their customers the latest technology, including AI/ML technology, serverless computing, and containerized application development.
  • Less server management: ​​Your cloud provider manages your servers and network hardware. This eliminates the need for additional IT personnel and ultimately saves money.
  • Scalability: Cloud resources are highly scalable and can handle sudden demand or traffic spikes. This makes the public cloud very useful for small and medium-sized businesses (SMBs) and startups. Start-ups can run a small setup without making large infrastructure investments, which are capital expenditure items with no guaranteed returns or guarantees.
  • Flexibility: Customers can access all public cloud services from a single dashboard. For small and medium-sized businesses, including established software development companies, startups, and other enterprises, the flexibility that the public cloud offers is a huge advantage. No one wants a huge infrastructure, and no one wants to be in a situation where their business growth is hampered due to a lack of server resources. You can subscribe to or unsubscribe from different cloud services based on your changing requirements. The monthly cloud service fee varies accordingly. This results in a very manageable OPEX item rather than a huge capital expenditure item.
  • Security: Standard public cloud security measures, such as protection against DDoS attacks and anti-malware protection, are an improvement for small and medium-sized businesses from a security perspective.
