Hosting

Hosting in IT refers to the process of providing infrastructure and services that allow websites, applications, or services to be accessible over the internet or a private network. A hosting provider offers computing resources such as servers, storage, networking, and security to run and maintain digital content.

Types of Hosting:

1. Shared Hosting – Multiple websites share the same server resources, making it cost-effective but less performant.
2. VPS (Virtual Private Server) Hosting – A single physical server is divided into virtual machines, offering more control and better performance than shared hosting.
3. Dedicated Hosting – A client rents an entire physical server, providing maximum performance, security, and control.
4. Cloud Hosting – Websites and applications run on a distributed network of virtual servers, offering scalability and high availability.
5. Managed Hosting – The hosting provider takes care of server management tasks such as maintenance, security, and updates.
6. Serverless Hosting – Developers deploy code without managing servers; cloud providers handle resource allocation dynamically.

Key Components:

• Servers – Physical or virtual machines that store and process data.
• Storage – Databases or file systems that hold content and application data.
• Networking – Internet connectivity, DNS, and content delivery networks (CDNs) to route traffic efficiently.
• Security – Firewalls, SSL certificates, and monitoring tools to protect hosted content.

Hosting can be self-managed (on-premises or in a data center) or outsourced to third-party providers like AWS, Google Cloud, and Azure.
