Cloud computing refers to a convenient way of accessing computer resources whenever needed through the internet. It spares organizations from the hassle of acquiring, setting up, and overseeing these resources on their own. Instead, they can simply use what they require and pay only for what they use.

How Does Cloud Computing Work?

Cloud computing service models are designed to allow organizations to share computing resources, software, and information over the internet. This means that companies or individuals can pay to access a pool of virtual resources, such as computing power, storage, and networking services. These resources are stored on remote servers owned and managed by service providers.

To put it simply, cloud computing works by connecting users to a cloud platform via a network, often the internet. From there, users can request and access rented computing services. A central server facilitates communication between the users’ devices and the servers, enabling the exchange of data.

Security and privacy features are integral to ensure the protection and confidentiality of this information. Clouds can be built using proprietary or open source software. Proprietary is sometimes more user friendly but open source often gives users more control and flexibility.

When it comes to adopting cloud computing architecture, there isn’t a one-size-fits-all solution. What may work for one company might not be suitable for another. This flexibility and adaptability are key characteristics of cloud computing. The ability for enterprises to quickly respond to changing market conditions or operational requirements, move workloads across cloud types, and even switch providers to keep infrastructure costs down allow organizations to flourish in an ever-changing economy. 

Cloud Computing Service Models

There are three primary types of cloud computing service models that cater to different levels of control, flexibility, and management requirements for organizations:

Infrastructure as a Service (IaaS)

Infrastructure as a Service (IaaS) provides on-demand access to IT infrastructure resources such as computing power, storage, networking, and virtualization. This model gives organizations a high level of control over their IT resources.

Platform as a Service (PaaS)

Platform as a Service (PaaS) offers a complete set of hardware and software resources required for cloud application development. With PaaS, companies can focus solely on developing applications without the need to manage and maintain the underlying infrastructure. This allows for streamlined application development and deployment processes.

Software as a Service (SaaS)

Software as a Service (SaaS) delivers a full application stack as a service, encompassing not only the underlying infrastructure but also the maintenance and updates to the application software itself. SaaS solutions are typically end-user applications, where both the service and the infrastructure are managed and maintained by the cloud service provider. This model provides convenience and eliminates the need for organizations to handle application management tasks.

It’s common practice that SaaS and PaaS use an IaaS provider. So organizations choosing to use SaaS or PaaS should inquire to know who provides the infrastructure.

Types Of Clouds

There are multiple deployment models in cloud computing: public cloud, private cloud, alternative and hybrid cloud. Each model has its own characteristics and considerations, depending on the specific needs and preferences of the organization. 

Public Clouds

Public clouds are operated by cloud service providers who are not affiliated with any specific organization. These providers offer computing, storage, and networking resources over the internet. This allows organizations to access and utilize shared resources based on their individual requirements and goals.

Resources are shared and users have no idea what other users share the servers their workloads are on. Public clouds are a great starter point for small workloads at the instance level, but once your workload grows significantly to $20,000 -$50,000 a month, you should be conscious that hosted private clouds can cost up to 80% less.

On-Premise Private Clouds

These clouds are built, managed, used and owned by the same organization. They provide organizations with a higher level of control, security, and data management. Internal users can benefit from a shared pool of computing, storage, and networking resources while ensuring that sensitive data remains within their own infrastructure. However, they are costly to set up (hardware cost and engineering time set aside to building and configuring the cloud) and maintain. There is also a longer wait time to scale because you need to purchase hardware and wait for it to be set up.

Alternative Clouds

Alternative cloud solutions such as hosted private clouds combine the best of both public and private clouds. They provide full root level control over your infrastructure and cost-effective pricing. Organizations can meet their specific IT infrastructure needs and ensure that their data is secure at all times. Alternative clouds can reduce your public infrastructure costs by 80%+ which allows you to enjoy the perks of both public and private clouds. Learn More

Hybrid Clouds

Hybrid clouds combine elements of both public and private cloud models. This cloud model allows organizations to build their cloud combining resources from multiple cloud providers and even on-prem. This allows organizations the flexibility to shop around and not over spend for resources when they need it. It allows companies to leverage public cloud services while maintaining the security and compliance capabilities typically associated with private cloud architectures.

By adopting a hybrid cloud approach, organizations can take advantage of the scalability and flexibility offered by public clouds while keeping critical data and applications in a controlled and secure environment.
