• Distributed Storage: Data is spread across multiple servers and data centers. 
• Sharding: Data is divided into smaller "shards" for efficient storage and retrieval. 
• Replication: Copies of data are stored in different locations for redundancy. 
• NoSQL Databases: Used for scalability and handling unstructured data. 
• Object Storage: Large files like images, videos, other files are stored.
• Caching: Frequently accessed data is kept in memory for faster retrieval. 
• Indexing: Data is organized and indexed for quick searches. 
• Load Balancing: Distributes traffic evenly across servers. 
• Security & Encryption: Data is encrypted for protection.

Difference between Shared and Dedicated Hosting

Shared Hosting

Types of Hosting

Shared Hosting

• Shared hosting is best for entry-level website hosting. Here our website will be stored on the same server as multiple other websites. 
• With shared hosting plan, all domains share the same server resources, such as RAM, CPU. 
• Here as all the resources are shared, the cost of shared hosting are low.
• Here we get limited storage, RAM and CPU etc.

Dedicated Hosting

• This type of hosting is best for large websites with high traffic.
• Here we have an entire physical server just for our website. 
• Here we have full control over the physical environment like we the hardware, the software, and so on.
• We have have full root and admin access.
• It is very expensive hosting
• Here we must require technical knowledge for setting up the server.

VPS Hosting

• This type of hosting plan is middle ground between a shared server and a dedicated server. 
• It is ideal for website owners that need more control, but don’t necessarily need a dedicated server.
• VPS hosting is unique because each website is hosted within its own space on the server, though it still shares a physical server with other users. 
• This hosting provides website owners with more customization and storage space, but still not able to handle high traffic levels.

Cloud Hosting

• It means many computers working together, running applications using combined computing resources. 
• Cloud hosting utilizes a network of interconnected virtual servers hosted in data centers around the world. 
• This is scalable, meaning your site can grow over time, using as many resources as it requires and while the website owner only pays for what they need.
• It is a very expensive hosting.
