Hello, friend!

Three common cloud service delivery modes are IaaS, PaaS, and SaaS. Let's introduce them separately.

There are three main cloud service delivery models:

  1.    Software as a Service (SaaS)

  2.    Infrastructure as a Service (IaaS)

  3.    Platform as a Service (PaaS)


1. Software as a Service(SaaS)

SaaS is the most well-known of the three cloud service delivery models. That’s because most people use SaaS applications every day, whether they know it or not. When people talk about “the cloud,” they’re often talking about SaaS applications like Google Drive, Dropbox, or even Netflix.  

The SaaS delivery model lets users access fully functional software that’s managed and run in the cloud. Users typically access SaaS applications through a web browser. The advantage of this is that you don’t have to worry about downloading and installing programs, because the vendor takes care of that. Although, you may have to download a plugin depending on the service you’re using. 

Some key benefits of SaaS include: 

  • It’s lightweight: Running SaaS applications doesn’t typically require as many computing resources as on-premises software. 

  • No need for software updates: Vendors manage and update SaaS applications. That means everyone has access to the most up-to-date version at all times. 

  • No more software licensing: Premium SaaS applications follow the subscription model, which means you don’t have to worry about buying and renewing software licenses. 

SaaS is popular among businesses, especially companies that employ remote workers. It allows them to use powerful business tools without needing to upgrade hardware or manually update software. 

2. Infrastructure as a Service (IaaS)

Traditionally, a company’s IT infrastructure was stored on-premises. This meant that companies had to constantly invest in expensive hardware like servers and storage and ensure everything stays up to date.  

As technology grew, companies turned to cloud service providers to help with managing their IT infrastructure. Thus, IaaS was born––and companies began transitioning from on-premises to cloud infrastructure.  

IaaS enables businesses to access virtualized computing resources from cloud servers.  

Benefits of using IaaS include: 

  • Greater flexibility: IaaS lets you access infrastructure services on demand. You can scale infrastructure to support business growth and reduce it when needed. 

  • Cost savings: You don’t have to buy physical hardware every time you want to upgrade. Your computing infrastructure is provided on a subscription basis, meaning your vendor is the one responsible for infrastructure management. 

  • Reliability: Your assets are stored in a remote data center, where it’s managed by cloud service providers. This service model all but eliminates the threat of a single point of failure. 

IaaS eliminates the need for in-house hardware, meaning organizations get state-of-the-art IT infrastructure at a fraction of the cost. This makes IaaS a popular service model for small and medium-sized companies. It helps level the playing field by enabling them to compete with larger organizations with bigger budgets, because they don’t have to invest in hardware and they can scale their infrastructure on demand. 

3. Platform as a Service (PaaS)

This type of cloud service delivery model is also known as a solution stack. It enables organizations to create, run, and manage cloud-based software without the need for onsite infrastructure. Platforms are provided and maintained by a third-party vendor. This means businesses don’t have to worry about activities like backups and provisioning servers––it’s all done for them. 

Benefits of PaaS include: 

  • Improved efficiency: Since a third party handles your IT infrastructure needs, businesses can spend more time focusing on developing, testing, and deploying applications. 

  • Simplicity: PaaS gives businesses a platform with development tools, so they can develop, test, and host applications in the same environment. 

  • Better collaboration: PaaS requires teams to develop over the internet, eliminating the need to transfer files and manually sync data. Everyone works with the same up-to-date information at all times.
