What is Cloud Computing?

Cloud computing is the on-demand delivery of computing resources, such as servers, storage, databases, networks, software, analytics, and intelligence, over the internet. Cloud computing eliminates the need for users to own, maintain, or operate physical devices and software, and instead allows them to access and use these resources as services from a cloud provider. Users only pay for the resources they use, and can scale up or down as needed.

Cloud computing is based on the concept of sharing a pool of resources among multiple users, which are located on remote servers that are owned and managed by cloud providers. These servers are connected through a network, usually the internet, and can communicate with each other and with the users’ devices. Cloud computing also relies on various technologies, such as virtualization, containerization, orchestration, automation, and encryption, to enable efficient and secure delivery of cloud services.

Types of Cloud Computing Services

Cloud computing services can be categorized into three main types: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). Each type of service provides a different level of abstraction, control, and responsibility for the users and the cloud providers.

Infrastructure as a Service (IaaS)

IaaS is the most basic type of cloud service, which provides users with access to raw computing resources, such as servers, storage, and networks. Users can rent these resources from a cloud provider, and use them to run and manage their own applications and operating systems. Users have full control and responsibility over the configuration, security, and maintenance of these resources, while the cloud provider takes care of the underlying hardware and infrastructure.

IaaS is suitable for users who need a high degree of flexibility and customization, and who have the technical skills and resources to manage their own infrastructure. IaaS is also ideal for users who have variable or unpredictable workloads, and who need to scale up or down quickly and easily. Some of the common use cases of IaaS are hosting websites, running big data analytics, testing and development, and disaster recovery.

Some of the examples of IaaS providers are Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and IBM Cloud.

Platform as a Service (PaaS)

PaaS is a type of cloud service that provides users with a ready-to-use platform for developing, deploying, and managing applications. Users can access a variety of tools and services, such as programming languages, frameworks, libraries, databases, and middleware, from a cloud provider, and use them to create and run their own applications. Users do not have to worry about the underlying infrastructure, security, or maintenance of these tools and services, as the cloud provider handles them.

PaaS is suitable for users who want to focus on the development and innovation of their applications, and who do not want to deal with the complexity and hassle of managing their own infrastructure. PaaS is also ideal for users who want to leverage the latest technologies and frameworks, and who want to collaborate with other developers and users. Some of the common use cases of PaaS are web and mobile app development, business intelligence, data integration, and internet of things (IoT).

Some of the examples of PaaS providers are AWS Elastic Beanstalk, Azure App Service, Google App Engine, and Heroku.

Software as a Service (SaaS)

SaaS is the most advanced type of cloud service, which provides users with access to fully functional and ready-to-use software applications over the internet. Users can use these applications for various purposes, such as email, productivity, collaboration, customer relationship management, and enterprise resource planning, without having to install, update, or maintain them. Users only pay for the subscription or usage of these applications, and can access them from any device and location. Users have limited control and responsibility over the configuration, security, and performance of these applications, as the cloud provider manages them.

SaaS is suitable for users who want to use software applications that are easy to use, reliable, and secure, and who do not want to invest in or manage their own software and hardware. SaaS is also ideal for users who have standard and predictable workloads, and who need to access their applications from anywhere and anytime. Some of the common use cases of SaaS are email, office suite, video conferencing, project management, and accounting.

Some of the examples of SaaS providers are Google Workspace, Microsoft 365, Zoom, Slack, and Salesforce.

Types of Cloud Computing Deployment Models

Cloud computing deployment models refer to the different ways of hosting and accessing cloud services, depending on the location, ownership, and management of the cloud infrastructure. There are three main types of cloud deployment models: public cloud, private cloud, and hybrid cloud. Each type of deployment model has its own advantages and disadvantages, and users can choose the one that best suits their needs and preferences.

Public Cloud

Public cloud is the most common and widely used type of cloud deployment model, which involves using cloud services that are hosted and managed by a third-party cloud provider, and that are available to the general public over the internet. Users can access these services on a pay-as-you-go basis, and share the same pool of resources with other users. Users do not have to worry about the cost, maintenance, or security of the cloud infrastructure, as the cloud provider takes care of them.

Public cloud is suitable for users who need a low-cost, scalable, and flexible solution, and who do not have strict regulatory or security requirements. Public cloud is also ideal for users who have non-sensitive or non-critical workloads, and who need to access their services from anywhere and anytime. Some of the common use cases of public cloud are web hosting, email, file storage, and online gaming.

Some of the examples of public cloud providers are AWS, Azure, Google Cloud, and Alibaba Cloud.

Private Cloud

Private cloud is a type of cloud deployment model that involves using cloud services that are hosted and managed by a single organization, and that are available only to its authorized users over a private network. Users can access these services on a dedicated or self-service basis, and have exclusive access to the resources. Users have more control and responsibility over the cost, maintenance, and security of the cloud infrastructure, as the organization manages them.

Private cloud is suitable for users who need a high-performance, secure, and compliant solution, and who have strict regulatory or security requirements. Private cloud is also ideal for users who have sensitive or critical workloads, and who need to customize their services to their specific needs. Some of the common use cases of private cloud are banking, healthcare, government, and education.

Some of the examples of private cloud providers are VMware, Dell EMC, IBM, and Oracle.

Hybrid Cloud

Hybrid cloud is a type of cloud deployment model that involves using a combination of public and private cloud services, and that are connected by a common network or platform. Users can access these services on a hybrid or multi-cloud basis, and have the best of both worlds. Users can leverage the cost-efficiency, scalability, and flexibility of public cloud, and the performance, security, and compliance of private cloud. Users can also move their workloads and data between the different cloud environments, depending on their needs and preferences.

Hybrid cloud is suitable for users who need a balanced, resilient, and versatile solution, and who have diverse and dynamic workloads. Hybrid cloud is also ideal for users who want to avoid vendor lock-in, optimize costs, and enhance application performance. Some of the common use cases of hybrid cloud are disaster recovery, data backup, data analytics, and cloud bursting.

Some of the examples of hybrid cloud providers are AWS Outposts, Azure Stack, Google Anthos, and IBM Cloud Pak.

Benefits of Cloud Computing
