Cloud Services
PLEASE USE THE CONTACT PAGE: If you need any consulting help.
Cloud services refer to the delivery of computing resources, including servers, storage, databases, networking, software, and analytics, over the internet. Instead of owning and maintaining physical infrastructure, users can access these resources on-demand from cloud service providers, paying only for what they use.
There are several categories of cloud services:
Infrastructure as a Service (IaaS): IaaS provides virtualized computing resources over the internet. Users can rent virtual machines, storage, and networking infrastructure from cloud providers, allowing them to deploy and manage their applications without having to invest in physical hardware.
Platform as a Service (PaaS): PaaS offers a platform that enables developers to build, deploy, and manage applications without dealing with the underlying infrastructure. PaaS providers typically offer development tools, middleware, database management systems, and other resources to support application development and deployment.
Software as a Service (SaaS): SaaS delivers software applications over the internet on a subscription basis. Users can access these applications through a web browser or API without needing to install or maintain any software locally. Common examples of SaaS include email services, customer relationship management (CRM) software, and productivity suites.
Function as a Service (FaaS): FaaS, also known as serverless computing, allows developers to execute code in response to events without managing server infrastructure. Cloud providers dynamically allocate resources to run code snippets (functions) in response to triggers such as HTTP requests, database events, or file uploads.
Database as a Service (DBaaS): DBaaS provides managed database services over the internet. Users can provision, scale, and manage databases without dealing with the underlying infrastructure. DBaaS offerings include relational databases, NoSQL databases, and data warehousing solutions.
