All about Cloud Storage and How it works.
                     ALL ABOUT CLOUD 
STORAGE AND HOW IT 
WORKS
INTRODUCTION
• Cloud storage involves at least one data server that a user connects 
to via the internet. 
• It involve vast numbers of data servers to ensure their availability.

WHAT IS THE CLOUD?
• It is a collection of networked computer hardware that works 
together to provide many aspects of computing in the form of online 
services. 
• We can control it remotely via web interfaces.

CLOUD DATA STORAGE 
RESOURCES
• By end users using a web interface that are paying for capacity on a 
per-transaction basis
• By the service provider which allocates resources dynamically as 
needed. 
• Payment is on a pay-per-use basis.

PUBLIC VS. PRIVATE CLOUD
• Public cloud storage resources are owned and controlled by third-
party service providers while private cloud infrastructure is owned 
and controlled in-house.
• public cloud storage includes upgrades; private clouds do not.

PUBLIC VS. PRIVATE CLOUD
• public cloud storage infrastructure is shared by a population of users; 
private cloud storage is dedicated to the company that owns it.
• Public cloud storage replicates data; private clouds in a single location 
could be destroyed by a natural disaster.

CLOUD STORAGE VS CLOUD 
COMPUTING
• Cloud storage involves stashing data in a remote physical location, 
which can be accessed from any device via the internet. 
• Cloud computing involves clients connecting to remote computing 
infrastructure via a network, but infrastructure includes shared 
processing power, software and other resources

• Virtualized infrastructure with accessible interfaces
• Elasticity and scalability
• Multi-tenancy and metered resources
• Capabilities to object storage
