Cloud computing is on-demand access to all your cloud computing resources. Cloud computing solutions enable you to access remote servers housed within large data centers, allowing you to gain higher flexibility and scalability over traditional on-premise infrastructures. Experts believe that global cloud computing will reach a whopping US$832 billion by the end of 2025.

In this article, we will discuss the major types of cloud computing and their basic components for operation. We will also discuss some of the benefits and challenges of deploying cloud solutions within modern business environments. 

But first, let’s focus on the different types of cloud computing present in this modern digital world.

Types of Cloud Computing

Organizations can choose to upgrade their traditional frameworks with different types of cloud computing, depending on security, costs, and scalability. 

Here are the major types of cloud computing in this modern digital world:

1. Public Cloud

• A public cloud makes computing resources available to users over the public internet. 
• These include SaaS applications, individual virtual machines, and development platforms. 
• The resources are either free or have a pay-per-usage pricing model. 
• A public cloud requires a high-bandwidth network connectivity to ensure high performance. 

2. Private Cloud

• It is a cloud environment where all the cloud infrastructures and resources have access to only one customer. 
• A private cloud offers various benefits, such as scalability, flexibility, and ease of service delivery. Moreover, users have enhanced security and resource customization compared to on-premise infrastructures. 
• A private cloud hosts a customer’s data centers. However, it can also be present in independent infrastructures or offsite data centers. 

3. Hybrid Cloud

• It is a combination of public, on-premise, and private clouds, providing flexibility in organizations' workflows. 
• There is high data security for hybrid clouds because data is properly separated, reducing the overall chances of data theft. 
• Hybrid clouds are cost-effective for organizations, providing portability and automated deployment of workloads across multiple environments. 
• Hybrid clouds have a feature called cloud bursting, where companies can scale their resources depending on traffic volume to maintain the efficiency of private cloud workloads. 

4. MultiCloud

• Muticloud makes use of two or more cloud services, which include SaaS, PaaS, and IaaS. 
• Instead of merging public and private clouds, a multi-cloud uses several public clouds. 
• Organizations with multi-cloud deployment have a high availability of services. 
• A multi-cloud has reduced latency to improve user experience. 

Remember, multi and hybrid-cloud aren’t just trends; they are key factors for business flexibility and resilience.

Having a comprehensive overview of the different types of cloud computing is critical before understanding the basics of cloud computing. 

Let’s look at the primary components that form a cloud computing environment. 

Primary Components for Cloud Computing

Cloud computing majorly relies on storage and networking to function effectively. 

Here are some of the core components that define a cloud computing environment:

1. Data Centers

Cloud Service Providers (CSPs) operate with remote data centers that bear physical cloud storage to create infrastructure and provide the foundation for cloud computing. 

2. Virtualization

Cloud computing depends on virtualizing IT infrastructure using specific software to pool resources irrespective of physical hardware boundaries. For example, a single hardware piece can be divided into several virtual servers. Virtualization also allows cloud providers to maximize the usability of their data center resources. 

3. Networking Capacity

Cloud computing demands high-speed networking connections, and a wide-area network (WAN) connection is typical for a cloud infrastructure. Other advanced cloud computing networking technologies, like load balancers, software-defined networking (SDN), and content delivery networks, are also common in this modern digital landscape. These advanced networking technologies ensure efficient data flow between front-end users and back-end resources. 

Cloud computing components define the workings of cloud architecture. However, an insecure cloud environment can hinder your business operations. 

Next, we listed key security considerations that are fundamental to cloud computing architectures. 

Cloud Security Considerations

Maintaining security standards for your cloud environment is a priority to keep the overall efficiency of your cloud application. Moreover, the cloud application market might reach $168.6 billion by 2025, making it necessary for businesses to undertake robust security strategies for an efficient cloud infrastructure.

We isolated some of the core security considerations for a cloud computing infrastructure those are as follows:

• Shared responsibility for security: CSPs and customers need to share security responsibility. In most cases, CSPs are responsible for protecting the overall cloud infrastructure, and customers are responsible for protecting their resources within a cloud environment. 
• Collaborative management: Clear communication to understand the processes between IT, operations, and security teams ensures seamless cloud integrations for a secure and sustainable cloud infrastructure. 
• Data encryption: Data that is constantly in use must be encrypted, and customers must have complete control over the security keys and modules. 
• Compliance and security monitoring: It is critical to fully understand all the regulatory compliances and standards applicable within specific industries. It establishes active monitoring of all connected cloud services to maintain overall visibility across all cloud environments, such as on-premise, private, and hybrid. 

Maintaining security standards for your cloud infrastructure is vital for extracting the most of your cloud applications. But what cloud solutions are available today that you can use in your organization?

Cloud Computing Solutions

Cloud computing solutions are prevalent within businesses nowadays to upscale their operations and improve their overall productivity to secure long-term success. 

Some prominent cloud computing solutions for a successful cloud infrastructure are as follows:

1. IaaS (Infrastructure-as-a-Service)

• IaaS provides on-demand access to necessary resources such as networking, cloud storage, and physical and virtual services over the Internet. 
• It offers users enhanced scalability, reducing the overall dependence on unnecessary on-premise infrastructures during spikes in cloud usage.

2. PaaS (Platform-as-a-Service)

• Provides on-demand platform software, hardware, and development tools to operate and manage applications with streamlined costs.
• It also provides flexibility in maintaining platform-on-premises. 
• Nowadays, containers are the primary components for building PaaS, which is a virtual computing model. Containers offer virtualization to operating systems, enabling developers to package applications within a single operating system service without the need for extensive modifications. 

3. SaaS (Software-as-a-Service)

• It is an interactive application hosted within clouds. Experts believe it will dominate the market with a projected market volume of US$390.46 billion in 2025.
• Users access SaaS applications through application programming interfaces (APIs), which integrate within mobile or desktop operating systems. 
• SaaS applications offer streamlined costs and scalability to users. Some other benefits of SaaS applications include automatic upgrades and security from data losses. 

4. Function as a Service (FaaS)

• FaaS allows developers to write and deploy small, independent functions to perform specific operations that are often event-driven, such as HTTP requests, database events, or time-based events. 
• It is a key component for serverless architectures, which offload back-end infrastructure management tasks to the cloud provider. 
• FaaS is a subset of serverless architectures and is not to be confused with serverless computing.

With these cutting-edge solutions in mind, you can upscale your business to the next level. Let’s see how such solutions benefit you in this modern digital landscape.
