The Types of Cloud Models in Cloud Computing

Cloud computing businesses have been around since the beginning of the 21st century and yet, many people are still unfamiliar with what it means and how it can benefit them or their businesses. If you’re looking to take advantage of this exciting new technology, there are several types of cloud models available to suit any number of needs and budgets. This article will explain each type and tell you where to go next if you’re ready to move your business into the cloud!

Infrastructure as a Service (IaaS)

IaaS is a great starting point for companies that want to set up their own cloud infrastructure. Providers like Amazon Web Services, Rackspace and Microsoft Azure offer IaaS with different levels of automation. You can choose to build your entire platform on IaaS or layer it on top of a PaaS solution (see below). Because it’s so flexible, some consider IaaS to be real cloud computing because there are no software licenses to buy and you can run whatever you want on your own servers (within reason). It’s also very cost-effective since customers only pay for what they use. The main downside is that IT infrastructure management becomes even more important as an organization scales up its workloads, requiring additional time and expertise. In addition, if something goes wrong with your server, you have to figure out how to fix it yourself or call someone who can. But if you’re just getting started and don’t need complex services such as autoscaling or load balancing, IaaS might be a good fit.

Platform as a Service (PaaS)

With PaaS, you can store and manage your own data in a database on someone else’s hardware. Hosting providers like Amazon Web Services and Microsoft Azure offer PaaS platforms with different kinds of databases (such as MySQL, MariaDB, SQL Server, etc.). With PaaS, you don’t need to worry about setting up and maintaining hardware the provider takes care of that for you. You also don’t need to worry about software; everything is managed by your hosting provider. However, if your code uses something like NodeJS or Ruby on Rails which is fairly common among startups you might have a little trouble getting it working with an existing system.

Software as a Service (SaaS)

The most common model that people associate with cloud computing is Software as a Service (SaaS). This approach involves users paying for software as they use it over time. The great thing about SaaS is that you can use a free trial to find out if it works for you before making a decision, and since your data lives on servers at an outside company, you don’t have to worry about keeping sensitive information safe. It also makes upgrades easy since new versions are automatically applied and supported. Businesses can buy or rent licenses as needed without having to invest in physical infrastructure or even licenses they’re not using and each user only pays for what they need, which reduces both cost and complexity.

Storage as a Service (STaaS)

This is one of two essential cloud computing services, and it’s provided by companies like Amazon Web Services, Microsoft Azure, IBM Bluemix and Google. It simply means you pay a company to store your data for you on their servers. When you need access to that data, it’s there instantly via the internet. This can be a cost-effective way to keep important records or documents or even your company website securely stored while freeing up space on your own devices or servers. This is an ideal solution for businesses that have employees working remotely because they don’t have to rely on emailing files back and forth; instead, any changes made are reflected across all versions of a file instantly through cloud storage.
