#iaas #paas #saas #techexplained

IaaS vs PaaS vs SaaS are terms that are everywhere in the cloud computing world these days. You’re not the only one who has ever been confused about what they mean or how they are different. These three models are the most important parts of cloud services. Each one has a different value for corporations, developers, and end users..

This guide will break all the down in simple and clear way, whether you’re a business owner trying to find the best cloud solution, a developer seeking for the ideal platform, or just someone who wants to learn more.

Cloud computing has changed the way people and organizations use technology. We can rent what we need over the internet instead of buying and taking care of pricey hardware and software. This is where IaaS, PaaS, and SaaS come into play.

Think of it like dining: you can cook everything yourself, order a meal kit, or dine in a restaurant, each approach has different levels of control and convenience. IaaS, PaaS, and SaaS are all alternative ways to use computing resources.

But what do these words mean, and how are they different from each other? Let’s make it easy to understand.

What Is Cloud Computing?

Cloud computing lets you use computing services including storage, servers, networking, and applications over the internet instead of on your own hardware.

It is online delivery of computing services like storage, servers, databases, software, networking, analytics, and many more. Companies can rent these services from a provider instead of buying and taking care of their own gear. They just pay for what they utilize.

You don’t have to buy a physical server. You may rent space and electricity from a cloud provider like Amazon Web Services (AWS), Microsoft Azure, or Google Cloud.

Key benefits of cloud computing:

Savings on costs (no need to spend a lot of money on infrastructure up front)
Scalability (easy to change resources based on need)
Access (you can get to it from anyplace with an internet connection)
Dependability (having built-in backups and redundancy)
Now, let’s look at how IaaS, PaaS, and SaaS fit into this.

Overview of IaaS, PaaS, and SaaS

These three types of cloud services provide you different amounts of control and let the supplier do different things for you.

IaaS: You rent IT infrastructure but set up much of it yourself.
PaaS: lets you rent a platform to design and run apps without having to worry about the infrastructure.
SaaS: You pay to use software that is already set up.
