Cloud Computing Systems for Dummies: Differences, Advantages and Uses between IaaS, PaaS and SaaS

cloud computing systemsCloud Computing is a general term for the delivery of hosted services over the Internet1. This is to say, a virtual mean to use computing systems whether as a storage center, virtual machine and/or utility.

 

Although Cloud Computing systems are part of the ordinary day-to-day, the term itself is still confusing for some people. This article brings a bit of light for those who still mix things up regarding its use and scope.

 

What are the origins of Cloud Computing systems?

 

We can trace the origins of cloud computing as back as 1960. In those days,  system engineers recognized and weighed the possible advantages of counting on cloud computing as utility or service. However, the Internet was still giving baby steps on those days; and it hasn’t evolved enough to withstand the demands of computing systems. In fact, Internet reached such optimal point in the late 90s; the moment when connectivity and bandwidth issues were robust enough to finally integrate computing as service:

 


In the late 1990s, Salesforce offered one of the first commercially successful implementations of enterprise SaaS. This was followed closely by the arrival of AWS in 2002, offering a range of services, including storage and computation — and now embracing databases, machine learning and other services. Today, Microsoft Azure, Google Cloud Platform and other providers have joined AWS in providing cloud-based services to individuals, small businesses and global enterprises.2

 

Almost 20 years have elapsed from that moment, and we still are discovering the potential uses of cloud computing systems. But let’s focus on its principal uses and types.

 

Cloud Computing systems: IaaS, PaaS, SaaS

 

Infrastructure as Service (IaaS)

 

Cloud infrastructure services, better known as Iaas, focus their systems as self-service applications created to access, monitor and manage remote infrastructures. Between the IaaS service, data and storage centers, firewalls, and others. If you still feel lost in definition; then the names Amazon Web Services (AWS), Microsoft Azure and Google Compute Engine (GCE) would give you the ultimate light on what IaaS is.

 

Among its use and advantages, we count huge additional storage capacity at low costs; connectivity between all your PCs; file synchronization and backup in the same spot that, additionally, you can access to from any device.

 

Platform as Service (PaaS)

 

Cloud computing as a platform is so flexible and versatile that you can use it to directly develop applications and complex systems to boost your virtual environments. In fact, PaaS systems provide virtual frameworks where your specialists can develop and customize proprietary systems and applications.

 

Besides offering the perfect spot to develop, your team can test, store and deploy complete apps and systems at low costs.  In consequence, your entire company benefit with better command of enterprise operations; virtualization; OS; storage centers and more.

 

Regarding the use of PaaS, this service model is perfect when we need to build systems and applications on ready-made bases to bring over users with technology. Also, the advantages of using PaaS tools is that your developers will only worry about optimizing and managing proprietary systems; applications, and data; without focusing on limited and complex functions usually resulting from using third-party programs.  

 

Again, if you still don’t associate PaaS with use, names like Google App Engine and Heroku will help you to build the necessary link among them.

 

Software as Service (SaaS)

 

Cloud application services, or better known as Software as a Service (SaaS); focus their virtues in the use of the web to hand over applications for pretty much everything, and everybody. This is the reason why it represents the largest market-based in the Cloud.

 

Third-party vendors use SaaS systems to directly deliver customer applications, and most clients prefer SaaS applications because they don’t need to download/install programs on their devices to use them. However, some SaaS applications demand special plugins to properly work.

 

So, enterprises that adopt SaaS easily streamline support and maintenance and program better their agendas to optimize workflows. And if all this explanation doesn’t help you to dispel your doubts, then names as Google Apps; Dropbox; Salesforce; Gmail, Mega and similar would give you the ultimate light on what SaaS is.

 

 

Cloud Computing Systems: Uses, applications and relevant differences

 

 

  • Target Groups

 

    • IaaS is devoted to computer engineers; PaaS to web developers; and SaaS to consumers.

 

  • Penetration

 

    • With IaaS we control applications, data, runtime, and middleware; with PaaS, we control applications and data; and with SaaS, we are only capable of consuming the contents of the applications.

 

  • Data Management

 

    • IaaS builds the data; PaaS deploys it and SaaS sells it.
