Public Cloud Services in 2023: Benefits, Limitations, and Pricing

December 30, 2022

Public cloud services are a great way to get your business up and running quickly. They offer the flexibility and scalability you need to meet the demands of your growing company without having to invest in expensive hardware or software. These are just some of the reasons why the public cloud market is expected to reach $800 billion in revenue by 2025.

But before you sign up for a public cloud service, it’s important to understand what it can do for you and how it will work with your business. This article will explore the benefits, limitations, and pricing of public cloud services.

What Is a Public Cloud?

The public cloud is a computing resource delivery model offered by third-party providers, according to which these resources are shared between multiple companies via the Internet, and each of the companies can use as much computing power as they need, following a pay-as-you-go approach.  The public cloud is one of three main cloud computing models available today, along with private and hybrid clouds. 

Many businesses choose managed public cloud services because they can save money on hardware and software costs, as well as other expenses related to running a data center. Public clouds also provide security and cloud disaster recovery services at no additional cost. Another benefit of the public cloud is that the whole infrastructure is managed by the provider, which is also responsible for ensuring data security and compliance. 

How Does the Public Cloud Work?

The public cloud is a technology that allows companies to store their data on a remote server. Instead of storing it on-premise, the business can store it in the cloud. It works by giving you access to a remote server. The server is hosted by a company like Amazon Web Services, Google Cloud, or Microsoft Azure that offers virtual machines that can be used by anyone who has subscribed for a service.

With a public cloud, the company can access its data from anywhere, and it’s stored in the same way your email is stored in Gmail: you can access a web-based interface that acts as a gateway to your files.

Public Cloud Architecture

If you’re considering migrating to the public cloud, it’s important to understand that there are three types of cloud architecture. Each type has its own advantages and disadvantages, so you have to choose one that meets your needs. These are Infrastructure as a service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Let’s review each of them in more detail. 

Infrastructure as a service (IaaS)

The first type is infrastructure as a service (IaaS). IaaS provides you with virtual machines that you can use to run applications on. It also includes storage, networking, and database services. The benefit of IaaS is that it gives you complete control over the virtual machine. This means that if something goes wrong with one of your servers, you can fix it yourself without having to wait for help from a cloud provider’s staff. The downside of IaaS is that it can be expensive if you need lots of resources or if your company needs high-performance infrastructure.

Platform as a service (PaaS)

PaaS gives developers everything they need to build and run their applications without worrying about managing servers or databases themselves. PaaS also includes development tools like IDEs and version control systems, so developers don’t have to spend time setting these up themselves, either. This model is great for startups who want to get started quickly and avoid setting up their own servers and infrastructure.

Software as a service (SaaS)

The third type is a software as a service (SaaS). SaaS gives users access to enterprise-level software through the cloud instead of installing it on their own machines. Software as a service (SaaS) gives users access to software applications that they can use right away, with no setup or maintenance required on their part. This model works best for businesses that want something simple but powerful that doesn’t require much maintenance. 

Public Cloud vs. Private Cloud vs. Hybrid Cloud

Using a public cloud service isn’t the only option to optimize data storage costs and protect your data. There are also private and hybrid clouds, and depending on the use case, each of them comes with its benefits and possible drawbacks.

Public Cloud

Public cloud computing is a model of IT that offers shared resources, applications, and services to multiple customers over the internet. This includes the use of virtualization, web services, and storage platforms that can be accessed via the internet. Public cloud providers offer various types of virtual machines (VMs) for customers to use in their software development lifecycle (SDLC). 

Private Cloud

Private cloud computing is an extension of on-premises infrastructure, where a company owns the physical servers and other equipment used in its data center. A private cloud allows companies to manage their own IT infrastructure without relying on an external provider for access or management purposes. This gives companies complete control over their data center resources, including power management, security policies, etc.

Hybrid Cloud

A hybrid approach involves using both public and private clouds as part of an enterprise IT strategy. Hybrid clouds allow you to combine the best features from both models – you get the security of a private cloud while still staying flexible as with a public cloud. However, hybrid cloud solutions are more expensive than either type of cloud alone because they require additional staff and resources to manage all the different parts.

Public vs. private vs. hybrid cloud – a comparison chart

Below is the comparison of public, hybrid, and private cloud models according to their cost, performance, scalability, and security features.

CostThe most affordable option if you choose the right service modelThe most expensive optionThe cost of a hybrid cloud is usually reasonable – it costs more than a private but less than a public cloud

Benefits of Public Cloud Computing

57% of businesses globally have already migrated their business processes to the managed public cloud, leveraging the benefits it comes with. Let’s find some of them below.

Ease of maintenance

One of the major benefits of public cloud computing is that it’s easy to maintain. When you use a public cloud service, you don’t have to worry about maintaining the hardware or keeping up with updates—the cloud provider will take care of all of that for you. You can just focus on getting your work done and let them worry about keeping things running smoothly.

Enhanced agility and unlimited scalability

Another benefit is enhanced agility and unlimited scalability. Public Cloud Computing allows you to scale up or down at any time. So, if your business needs a temporary boost in resources (for example, during a major marketing campaign), you can easily get those resources without having to buy new hardware for it since scaling happens behind the scenes.

Quick and easy setup

Public cloud computing allows users to quickly set up new servers without having to purchase hardware or configure physical infrastructure. This makes it ideal for startups that need to rapidly scale up their operations. The only thing you have to do is to choose a public cloud service provider and get in touch with a reliable tech vendor for cloud implementation services. 

Less server management

When you’re running your own servers, you have to do all the work yourself. You have to figure out how to set up servers, how to manage them, and how to keep them running smoothly. With public cloud computing, you don’t have to worry about any of that—you just sign up for an account with a provider like Amazon Web Services or Microsoft Azure and then pay for what you use (and only for what you use). That way, if your business grows or shrinks over time, it’s much easier to adapt.

Cost savings

Public cloud computing also has another benefit: it’s cheaper than private cloud computing. With public cloud computing, there are no upfront costs for equipment or maintenance fees because everything runs on a shared network of computers instead of just one computer that belongs solely to you. What’s more, each of the cloud service providers we have reviewed above offers different and flexible engagement models, which means that you can choose a package that suits your business best right now and then scale step-by-step. 

Drawbacks of Public Cloud Computing

In addition to the benefits, a public cloud has limitations. However, you can overcome most of them by choosing a trustworthy cloud service provider and having clear cloud adoption and migration strategies. 

Runaway costs

There are a few drawbacks to public cloud computing, but the biggest one is runaway costs. When you’re using the public cloud, you have to pay for every single hour that your application runs. This means that if you need to scale your application up or down based on demand, it can get very expensive very quickly. That’s why you have to be especially careful when choosing between a pay-as-you-go model and a fixed subscription fee. 

Security and compliance concern

Another possible issue with the public cloud is security and compliance concerns. Many businesses don’t feel safe storing their data with a third party, so they prefer not to use public clouds at all. But even if you are sure your cloud provider will not leak your data or compromise its security, there are still lots of regulations that apply to specific industries (for example, HIPAA compliance is a must for healthcare). Legal compliance requirements sometimes make it difficult to keep up with regulations while using a public cloud service.

Vendor lock-in

A vendor lock-in is an inability to move your data to another cloud provider. If you’re locked into one vendor, that means you can’t easily switch to another cloud provider since such a data migration project may cost a fortune. Sometimes, your business demands can also go beyond the public cloud capabilities your provider can offer. To avoid vendor lock-in, some companies choose to use multiple public cloud service providers, distributing their business processes and data among them.

What Is the Cost of Running Public Cloud Storage

As with custom software development, the only right answer to the question of the public cloud storage running cost is “it depends”. The cost of using a public cloud depends on the type of services you need. If you’re just looking for a place to store your data, there are many free options available. If your needs are more complex and require more resources, there are also many paid options at different price points.

The pricing model you will follow also matters significantly. Some public clouds are sold on a pay-as-you-go basis, so you only pay for what you use. The provider can also charge you per hour or per month, depending on your usage patterns. There are also tiered pricing plans, where you pay more for higher levels of service or resources. The mix of the options above is also possible. 

So, the best way to find out how much it will cost you is to review the provider’s website or speak with their sales team directly. Leading cloud providers also have pricing calculators on their websites. With their help, you can get a clear idea of how much running a public cloud will cost in your specific case. To get a realistic picture, you must specify the expected workload, the necessary computing power, and the request processing time. So, depending on the provider you choose, you can use the dedicated calculators:
