What Are the Different Levels Of Cloud Computing?

Cloud computing generally encompasses three primary service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). These levels differ in terms of the level of abstraction they provide to users, with each level offering a different degree of control and management responsibility. Businesses often engage both cloud consulting companies and cloud service providers to plan, implement, and manage their cloud infrastructure effectively.

Here’s a brief overview:

1.Infrastructure as a Service (IaaS):

In IaaS, cloud providers offer virtualized computing resources over the internet. These resources typically include virtual machines, storage, and networking capabilities.
Users have control over the operating systems, applications, and development frameworks running on the infrastructure, but they are responsible for managing these resources, including installing and maintaining software.
Example providers: Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP).

1. Platform as a Service (PaaS):

PaaS provides a platform allowing customers to develop, run, and manage applications without dealing with the underlying infrastructure.
It typically includes middleware, development tools, database management systems, and other services needed to support the complete lifecycle of building and delivering web applications and services.
Users focus on developing and deploying their applications, while the PaaS provider manages the underlying infrastructure and runtime environments.
Example providers: Heroku, Microsoft Azure App Service, Google App Engine.

1. Software as a Service (SaaS):

SaaS delivers software applications over the internet on a subscription basis, eliminating the need for users to install, maintain, and upgrade software locally.
Applications are accessed via a web browser or API, and users only need an internet connection and a compatible device to use them.
SaaS providers handle all aspects of software maintenance, including updates, security patches, and data backups.
Example providers: Salesforce, Microsoft Office 365, Google Workspace.
Cloud consulting companies offer services to help businesses navigate their cloud journey. They provide expertise in cloud architecture, migration strategies, security, compliance, cost optimization, and ongoing management. Some prominent cloud consulting companies include Accenture, Deloitte, Capgemini, and Cloud reach.

Cloud service providers, on the other hand, are the companies that offer the actual cloud computing resources and services, such as IaaS, PaaS, and SaaS. Examples include AWS, Azure, Google Cloud, IBM Cloud, and Oracle Cloud.

Businesses often engage both cloud consulting companies and cloud service providers to plan, implement, and manage their cloud infrastructure effectively.
