Brief Introduction of Cloud Services

Before the introduction of cloud services, deploying an application required a complete infrastructure to run a server. This included a machine with all the necessary accessories like sufficient RAM and hard disk space. Additionally, a dedicated space or garage was needed to house these machines for running server applications. It's clear that deploying an app to production demanded significant resources and financial investment, which still didn't guarantee that your server wouldn't slow down or crash at some point.

To tackle this major issue, cloud services were introduced. With cloud services, your application is deployed on a virtual machine located in a remote data center, accessible to you via the internet. This solution addresses multiple issues, including the infrastructure load on servers and many others.

Cloud services offer several benefits:

1. Scalability: Easily adjust resources based on demand

2. Cost-efficiency: Pay only for the resources you use

3. Reliability: Improved uptime and disaster recovery options

4. Flexibility: Access your application from anywhere with an internet connection

The major companies providing these services are Amazon with their AWS (Amazon Web Services) platform, Microsoft with Azure, and Google with their Google Cloud Platform. These cloud providers offer a wide range of services beyond just virtual machines, including storage, databases, AI and machine learning tools, and more.
