Since, the last recent years, cloud services have become the most demandable service, which has been made possible by major companies like Microsoft, Google, Amazon, and Oracle. Furthermore, corporations outsource storage to reputable vendors rather than depending on their private servers, ignoring their obligation to uphold the foundation and assure security.

Did You Know?

“Cloud-native systems will support more than 95% of new digital workloads by 2025, up from less than 30% in 2021,” predicts Gartner. 

Cloud Computing: A Quick Glance

Cloud computing refers to the method of network access. Besides, it enables convenient, on-demand network access to a shared pool of programmable computing resources (e.g., networks, servers, storage, applications, and services). Well, three service models, four deployment modes, and five important elements make up this cloud model.

Understand the Term Cloud Computing Service Models

Well, cloud computing service model consists of three main service models. Where, each of the model offers different levels of control, flexibility, and management. Consequently, you can choose a proper cloud computing service model based on your requirements.

What are the Three Common Cloud Computing Service Models?

There is some misunderstanding about the three major cloud service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS) (SaaS). Let’s break into each cloud service model. So, let’s examine each of them.

1. Infrastructure As A Service (IaaS):

It is the most flexible type of cloud service with the ability to rent hardware and the essential IT and cloud building blocks. Additionally, it offers complete control over the hardware that aids to run your program including servers, VMs, storage, networks & operating systems.

Furthermore, it is an online computer infrastructure that can be instantaneously provided and maintained. IaaS gives you the greatest administrative freedom and control over your IT resources. It resembles the typical IT resources that many IT departments and developers are used to very closely. Networking, storage, virtual machines, or AWS EC2 are some examples of IaaS.

Core Advantages of IaaS:

IaaS is a practical and economical method for setting up, managing, and expanding your IT infrastructure. You may start using it right away. This is because it’s easy to configure and set up. 

Additionally, since it is provided to you as a service from an outside source, you don’t have to worry about developing and maintaining your own infrastructure. Here, we have enlightened some of the following benefits of IaaS. So, let’s examine them.

1. Cost-Saving Measures:

IaaS is less expensive than building a data center from scratch. Therefore, you just pay for the resources you really use, such as bandwidth, CPU power, and storage space. This facilitates scaling up and down as necessary.

2. On-Demand Access:

Without spending money on additional IT staff or purchasing new hardware and software, you can immediately provide additional resources as needed. With 99.9% uptime assurance, the cloud provider manages all necessary maintenance and upgrades to keep your servers online 24 hours a day, seven days a week (or better).

3. Flexibility:

With cloud computing, you can easily add more resources as needed without having to upgrade your hardware or hire extra IT staff.

2. Platform As A Service (PaaS):

A ready-to-use development environment is offered by the PaaS cloud service paradigm. Although PaaS allows developers to concentrate on writing and running high-quality code to construct custom apps. 

It enables you to create applications quickly without having to handle the supporting infrastructure. For instance, you don’t need to install an operating system, a web server, or even system upgrades when using PaaS to launch a web application. However, you can expand and include additional features in your services.

This cloud service model makes it easier to design and deploy applications, and it costs more than IaaS but less than SaaS. Besides, you become more productive as a result of not having to worry about the other undifferentiated tasks associated with running your application, such as resource acquisition, capacity planning, software maintenance, patching, etc.

Did You Know?

“The value of the global PaaS market was USD 60.12 billion in 2021, and between 2022 and 2028, it is projected to rise at a CAGR of 19.3%.”

Oracle Database Cloud Service from Oracle Cloud, Elastic Beanstalk or Lambda from AWS, WebApps, Functions, or Azure SQL DB from Azure, Cloud SQL DB from Google Cloud, or Cloud SQL DB from Azure are a few examples of PaaS to consider.

Main Benefits of PaaS:

PaaS is the most easiest way that aids in building an application. Furthermore, it offers lots of gains. Some of them are the following –

1. Better Development Time:

You can’t build infrastructure before you start coding.

2. Minimizes the Costs:

There is no need to spend time and money on manual deployments and server management.

3. Improved Security:

PaaS providers offer better security rather traditional web apps by locking down your applications. 

4. High Availability:

While hardware failures or windows maintenance, PaaS providers ensure the availability of your application.  

Did You Know?

“By 2026, PaaS will make a revenue of $164.3 billion,” predicts TechTarget.

3. Software As A Service (SaaS):

SaaS gives you access to a fully functional product that the service provider runs and manages. The software is hosted online and made accessible to users via subscription or purchase in this cloud service model.

When you utilize a SaaS provider, you don’t have to worry about how the service is administered or the underlying infrastructure is maintained. Furthermore,  it might be helpful if you tried to picture how you would use that particular piece of software

Microsoft Office 365, Oracle ERP/HCM Cloud, SalesForce, Gmail, and Dropbox are some examples of SaaS.

Core Benefits of SaaS:

SaaS offers a wide range of advantages. Despite the fact that many companies have already shifted to SaaS, some are still hesitant. The following is a list of some of the strongest arguments in favor of moving to SaaS:

1. Minimum Ownership Cost:

One of SaaS’s most significant advantages is that it decreases your total cost of ownership (TCO) by doing away with the need for hardware and maintenance costs. It is no longer necessary to purchase servers or work with IT professionals to maintain or watch over them, which decreases the initial investment and ongoing maintenance costs.

2. Enhanced Security:

SaaS’s greater security is another benefit. There is less chance that hackers will gain access to or steal your data. This is because the majority of services are hosted on secure servers in data centers that are watched 24 hours a day. 

SaaS is therefore a more secure option than on-premise software or local servers for the storage of sensitive data. “Software as a service (SaaS) offerings do indeed offer better security than self-hosted software, according to Gartner’s 2017 Magic Quadrant report.”

Final Thought:

In the last few years, cloud computing become popular around the globe. Now, its demand is increasing day after day. Well, the cloud consists of three main cloud computing service models. When your business requires out-of-the-box software, SaaS (Software as a Service) will be the best option. If your business requires a platform for building an application, PaaS (Platform as a Service) will be the best option. Whereas, if your business requires a virtual machine, IaaS (infrastructure as a Service) will be the best option.
