Types of Cloud Computing
There are three main deployment models for those looking to start a career in cloud computing: public cloud, private cloud, and hybrid cloud.
Public Cloud
A public cloud is operated by third-party providers like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform (GCP). The cloud resources like servers and storage are owned and managed by the cloud provider at their data center. Customers access these public cloud services over the internet.
Public cloud services offer simplicity and cost-effective pay-as-you-go pricing since the infrastructure costs are spread across many customers. However, there are reduced levels of control and configurability compared to private cloud options. Public clouds can also present security and regulatory compliance concerns for some organizations dealing with highly sensitive data.
Private Cloud
A private cloud is a proprietary computing architecture operated solely for one organization. It can be physically located on-premises in the company’s data center or externally hosted by a third-party. The infrastructure dedicated to a single organization offers greater customization, security, and control – but requires more hands-on management and upfront investment.
Hybrid Cloud
Hybrid clouds integrate both public and private cloud infrastructure. For example, a company may host sensitive customer data and core applications on a private cloud while leveraging supplementary public cloud services. This “best of both worlds” approach gives organizations flexibility to design cloud architectures aligned with their functional and security needs.
Cloud Computing Service Models
There are three primary categories of cloud computing services:
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
These build on top of one another to provide different levels of abstraction and managed services.
Infrastructure as a Service (IaaS)
IaaS delivers fundamental compute, storage, and networking resources to customers on-demand. Rather than purchasing servers, data centers, hardware and network equipment, customers can access these resources as flexible, scalable services.
With IaaS, organizations still manage the operating systems, middleware, runtimes, data and applications. But the cloud provider owns and maintains the underlying cloud infrastructure. Leading IaaS providers include Amazon Elastic Compute Cloud (EC2), Microsoft Azure Virtual Machines, and Google Compute Engine.
Platform as a Service (PaaS)
PaaS goes one level beyond IaaS, providing a complete development and deployment platform in the cloud. Customers leverage pre-configured OS, programming languages, services, tools and APIs to build cloud-based applications without needing to manage the underlying infrastructure.
By relying on the cloud provider’s technology stack, programmers can focus on coding application logic and delivering business value. Leading PaaS providers include Salesforce’s Heroku, Amazon Elastic Beanstalk, and Microsoft Azure App Service.
Software as a Service (SaaS)
SaaS represents the most turnkey cloud computing model. Rather than developing or installing an application on-premises, customers simply access software applications hosted in the cloud via a thin client like a web browser.
Since the cloud provider manages everything from data to application code to infrastructure, the user only needs to think about how they will utilize the software. Common SaaS examples include Microsoft Office 365, G Suite productivity tools, Salesforce CRM and more.
Top Cloud Computing Use Cases and Applications
The on-demand availability and scalability of computing via the cloud unlocks innovation across many industry verticals and lines of business:
Data Storage
Rather than rely on local storage systems, companies can leverage highly durable and available cloud storage services like Amazon Simple Storage Service (S3), Google Cloud Storage and Microsoft Azure Blob Storage for data archiving, backup and disaster recovery needs.
Test and Development Environments
Software engineers can utilize cloud-based development environments to quickly stand up the infrastructure needed to rapidly build, iterate and test applications without provisioning physical systems. These cloud development platforms provide configurable middleware, tools, and services while automating infrastructure management.
Big Data Analytics
The immense compute power of the cloud supports big data initiatives that involve processing extremely large data sets for metrics and insights, like customer behavior analytics or supply chain optimization. Massively scalable cloud data warehouse solutions include Snowflake, Google BigQuery and Amazon Redshift.
Gaming
Leading gaming companies leverage cloud platforms to deliver online multiplayer games, game streaming services and interactive experiences to millions of concurrent users around the world through solutions like Amazon Game Tech, Microsoft Azure PlayFab, Google Stadia and more.
Media Streaming
Top streaming providers use the elastic capacity of cloud computing to encode, store and distribute video content to global audiences. Media processing and delivery cloud services underpin platforms like Netflix, YouTube, Spotify and more.
