Cloud Computing 101
OVERVIEWCloud computing revolutionizes the way we manage and utilize IT resources. This technology enables the delivery of various services over the internet, allowing users to access on-demand computing essentials like storage, servers, databases, networking, software, and more. By eliminating the need for physical hardware or software maintenance, cloud computing offers unparalleled scalability, flexibility, and cost-efficiency. |

What is cloud computing?
Cloud computing is the delivery of computing services over the Internet, such as storage, servers, databases, networking, software, analytics, and intelligence. It allows users to access and use these services on demand without having to buy or maintain physical hardware or software. Cloud computing offers many benefits, including scalability, flexibility, cost-efficiency, reliability, security, and innovation.
In general, there are several different ways that cloud computing is provided. All these options are subscription-based based depending on the needs to the service.
Option 1: IaaS – Infrastructure as a Service
Summary: IaaS environments are typically set up and managed by IT professionals. The professionals update, patch, and maintain the servers and software. They are simply renting the hardware.
Infrastructure as a service (IaaS) is a type of cloud computing that provides users with virtualized computing resources, such as servers, storage, network, and operating systems. Users can rent these resources from a cloud provider to run their applications and workloads. Users have more control and flexibility over the configuration and management of the infrastructure but also more responsibility. IaaS suits users who need high-performance computing, scalability, and customization. Examples of IaaS providers include AWS EC2, Azure Virtual Machines, and Google Compute Engine.
Option 2: PaaS – Platform as a Service
Summary: PaaS environments are typically set up by developers, and the PaaS provider provides server updates/maintenance. The provider rents the hardware and the core piece of software.
Platform as a service (PaaS) is a type of cloud computing that provides users with a platform to develop, deploy, and run applications without worrying about the underlying infrastructure. Users can access the platform services, such as programming languages, frameworks, tools, and libraries, from a cloud provider and use them to create and run their applications. Users have more control and flexibility over the application development and deployment but less responsibility for the infrastructure maintenance. PaaS suits users who need rapid and agile application development, scalability, and compatibility. Examples of PaaS providers include AWS Elastic Beanstalk, Azure App Service, and Google App Engine.
Option 3: SaaS – Software as a Service
Summary: SaaS environments are typically set up by end-users or managers. The SaaS provider maintains all hardware and software.
Software as a service (SaaS) is a type of cloud computing that provides users access to software applications hosted and managed by a cloud provider. Users can use the applications over the Internet, without installing or maintaining them on their own devices. Users pay for the subscription or usage of the applications and benefit from the cloud's convenience, scalability, and security. SaaS suits users who need ready-to-use and standardized applications, such as email, office productivity, customer relationship management, or enterprise resource planning. Examples of SaaS providers include Gmail, Microsoft Office 365, Salesforce, and Quickbooks Online.
What are the four types of cloud computing?
There are four main types of cloud computing based on the deployment model and the level of control and customization. They are:
- Public cloud: A public cloud is a cloud service that is owned and operated by a third-party provider, such as Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP). Users can access public cloud services over the Internet and pay only for the resources they use. Public clouds offer the most scalability, availability, affordability, and security and the least privacy.
- Private cloud: A private cloud is a cloud service dedicated to a single organization or customer and is usually hosted on-premises or in a private data center. Users can access private cloud services over a private network and have more control and customization over the resources and security. Private clouds offer the most protection, privacy, cost, and complexity.
- Hybrid cloud: A hybrid cloud is a cloud service that combines public and private clouds and allows data and applications to move between them. Users can leverage the best of both worlds and optimize their workloads' performance, cost, and security. Hybrid clouds offer the most flexibility, agility, management and integration challenges.
- Multi-cloud: A multi-cloud is a cloud service that uses multiple public cloud providers and distributes the workloads across them. Users can avoid vendor lock-in and choose the best cloud service for each task based on features, performance, cost, and availability. Multi-clouds offer the most diversity and redundancy but also the most complexity and compatibility issues.
How do you choose the right type of cloud computing?
There is no one-size-fits-all solution for cloud computing, and the choice depends on each user's specific needs and goals. Some of the factors to consider are:
- The type and size of the data and applications
- The level of security and compliance required
- The budget and operational costs involved
- The scalability and availability needed
- The level of expertise and support available
To make an informed decision, users should compare the pros and cons of each type of cloud computing and consult with cloud experts and providers. Cloud computing is a dynamic and evolving field, and users should always be ready to adapt and innovate as their needs and the market change.
