What is Cloud Computing?

The idea of cloud computing was first introduced in the 1950s. The concept of cloud computing is renting and delivering different computing services, including servers, data storage, databases, networking, and software, through the internet. Before cloud computing became usable, hardware tools did that job, and separate Information management technology services were maintained. Cloud computing became popular among people and businesses for cost savings, increased productivity, greater performance, speed, efficiency, and security.

What’s the difference between PaaS vs. SaaS vs. IaaS?

Each cloud model offers specific features and functionalities that differ from the others. It is essential to understand the differences before getting started to work with them in order to select the appropriate cloud service for your need. 

IaaS provides maximum flexibility by delivering virtual resources such as cloud computing infrastructure, servers, networks, operating systems, and storage. In the IaaS model, you are responsible for managing Applications, Data, runtime, middleware, and operating system, while the service providers are responsible for managing Virtualization, servers, storage, and networking. 

PaaS allows you to focus on app development instead of dealing with infrastructure management. In the Paas model, you are responsible for managing only applications and data, while the service provider responsible for managing runtime, middleware, operating system, Virtualization, servers, storage, and networking.  Modern PaaS services are built on top of an IaaS service.

Saas is a ready-made software solution that meets a certain business requirement. In SaaS models, everything is managed by the service provider. Modern SaaS services are built on top of IaaS or PaaS services.

Now let’s review the differences between PaaS vs SaaS vs IaaS and some examples.

IaaS vs PaaS vs IaaS: What you need to know about PaaS 

Platform as a Service (PaaS), also known as Cloud platform services, provides a platform for creating software. Developers can build customized applications using PaaS. While all servers, storage, and networking are managed by the third-party provider, developers have the freedom to concentrate on the software. 

The PaaS will be ideal if you want to create a unique and creative application without worrying about complicated tasks such as dealing with servers, managing software updates, storage, networking issues, and security patches. 

PaaS vs SaaS vs IaaS examples of PaaS features:
1. Built-in capabilities
2. Online services interfaces
3. Simple to integrate with other apps
4. Browser-based development platform

PaaS Features

Below are some of the key features of PaaS to understand the debate between PaaS vs IaaS vs SaaS.

  • PaaS provides a browser-based development platform. The developer can use point-and-click technologies or an Application Programming Interface to construct databases and change application code.
  • Within the same platform, PaaS is simple to integrate with other apps.
  • PaaS offers built-in capabilities for creating a workflow, approval procedures, and business rules.
  • Web service interfaces, scalability, and security are all included with PaaS.
  • Additionally, PaaS offers online services interfaces that let us integrate applications running on different platforms.

PaaS Advantages

Regardless of the size of the company PaaS offers several advantages.

  • Cost: All businesses that use PaaS benefit from reduced investment costs because it doesn’t call for software or hardware. The cost of installing and maintaining the program is nothing. The program can be used immediately without the need to make infrastructure investments.
  • Scalability: PaaS is a dependable scalability option because of its scaling technique. With regard to resources and tools, the ecosystem used in a PaaS is extremely scalable. The organizational structure is adaptable enough to enable corporate growth without significant expenditure. For small firms wishing to grow their resources and services, this is very advantageous.
  • Efficiency: The workplace that the PaaS offers already exists. They provide an already-created company strategy. This implies that every project need not be started from scratch. As a result, users cannot independently design new programs. Users can construct applications by using a common procedure.
  • Ability to upgrade: PaaS solutions must regularly update in order to stay competitive. Users risk continually missing out on new features and enhancements if updates are not provided on a regular basis. The applications are constantly running in the most recent versions, thanks to these updates. The PaaS supplier now automatically delivers the updates.
  • Support: It is essential for a company to create apps that work on a variety of platforms and devices. Developers of PaaS constantly ensure that their applications are compatible with a variety of platform types. They do this by using particular equipment suited for the job. PaaS ensures compatibility as a result.

PaaS Disadvantages

While using PaaS service, imperfections can be experienced in certain matters. Some of them are listed below. 

  • Security: The company’s cloud database houses all of the distributed applications. Since the provider can see the personal and sensitive information, this raises concerns about confidentiality. Thus, it is the duty of the companies to secure their apps by picking a reliable provider. If not, the security of the current information can be at risk.
  • Control: A PaaS solution gives users few controls. It depends on the capability of the provider. For instance, once the supplier changes its pricing structure, the applications may follow suit and become more expensive. It is crucial to make a sensible choice when selecting your PaaS supplier.
  • Integration: Every single PaaS provider has a unique integration method, similar to compatibility. It is not possible to merge two separate PaaS products. Contradictions are visible if tried. Additionally, switching PaaS providers is rarely a simple operation once integration problems arise.

PaaS vs SaaS vs IaaS examples of  features
1. Control from a single location
2. Hosted from a remote server
3. Accessible over the internet
4. Updates to hardware or software

SaaS Features

Below are some of the key features of SaaS to understand the differences between PaaS vs SaaS vs IaaS.

  • You can control from a single location
  • It is hosted from a remote server
  • It is accessible over the internet
  • Updates to hardware or software are not the users’ responsibility

SaaS Advantages

You will get several advantages by choosing SaaS. For instance:

Shorter time to gain: SaaS is different from the conventional concept because the software is already set up and configured. The application will be available for usage in a few hours after you’ve just provisioned the server for a cloud instance. By doing so, installation and configuration tasks take less time and there may be fewer obstacles to software deployment.

  • Cost: Since SaaS typically exists in a shared or multi-tenant setting with lower software and hardware license costs than the traditional approach, it can result in advantageous cost savings. 

Since the environment is owned by the SaaS provider and shared by all users of the application, maintenance expenses are also decreased.

  • Scalability: SaaS solutions typically exist in scalable cloud settings with integrations with some other SaaS products. You don’t need to purchase an additional server or piece of software in contrast to the conventional model. The SaaS provider will manage server capacity planning after you simply need to activate a new SaaS offering. 
    Recent releases: With SaaS, the vendor updates the product and makes it accessible to its clients. Compared to the conventional paradigm, which typically requires you to purchase and install an update package, the costs and work involved with upgrades and new versions are reduced.
  • Easy to use: SaaS products are simple to utilize because standard procedures and sample codes are already included. Users can conduct proof-of-concept tests in advance to evaluate the functionality of the product or a major update.

SaaS Disadvantages

Even though SaaS services are really useful, there are drawbacks. Some of them are listed below. 

Lack of control: Businesses have more control over in-house software applications than hosted solutions, where control is held by a third party. In most cases, users are required to utilize the most recent version of the software package and cannot delay upgrades or feature updates.

  • Data concerns: Cloud and hosted services raise serious security and data problems, including access control and the confidentiality of sensitive data.
  • A limited selection of applications: Despite SaaS’s growing popularity, many applications still do not provide a hosted platform.
  • Connection requirement: Because the SaaS model relies on web distribution, you may lose access to your program or data if your internet provider decreases.
  • Performance: Because SaaS software isn’t housed on a local workstation, it may operate at a slightly reduced speed than on-premise client or server applications.

  • Resources can be bought as required.

IaaS Advantages

By using IaaS, the most flexible cloud computing model, you can be beneficial in many ways.

  • Cost: When you migrate to an IaaS platform, your company will have a lot less to worry about in terms of infrastructure costs. You won’t need to invest in any hardware or other network equipment, keep it running, or worry about uptime.
  • On-demand scaling: If your company operates in a sector where demand varies seasonally, IaaS makes it simple to raise and decrease data storage requirements, the number of virtual machines being used, as well as the software applications used—all without requiring a sizable investment. 
  • Operational adaptability: Infrastructure solutions make it simpler to provide your staff with widespread access to the gear, processing capacity, and software applications they use on a daily basis.
  • Focus on expansion: You won’t have to worry about regularly hiring and training new IT workers as your company expands. Instead, you may concentrate on expanding your company while leaving the work of maintaining and updating infrastructure to help business operations to an IaaS provider.

IaaS Disadvantages

Even though IaaS is the most flexible cloud service, you will experience some limitations with it. Some of them are listed below. 

  • Security: If you lose management of your infrastructure, your private company information may be at risk. Businesses give up control of cloud computing to the hosting company in an IaaS setting. A hacked system threatens your operations even if there is a breach found in the system that doesn’t directly affect your data.
  • Lack of flexibility: You must rely on your cloud provider to maintain and upgrade cloud-based software in addition to the hardware. The provider’s failure to improve the programs you depend on for day-to-day operations could have a big impact on how effective your workforce is on a regular basis.
  • Technical issues: Some businesses may have IaaS downtime that is out of their control. Even though the majority of cloud services distribute the workload and bandwidth over a larger IaaS environment, any problem that develops on the provider’s end could limit your company’s access to the apps and data it depends on to complete its tasks.
