How to Use Saas Paas Iaas In Cloud Computing?

Advances in cloud computing have enabled the rise of SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service) models that are transforming business, government and society.

In this article, we’ll go over what cloud computing is, why businesses are switching to it, and how you can get started using this technology.

We’ve all heard of Salesforce, Google Apps, and Office 365. As more businesses move to the cloud, the question arises: what are the differences between these services? And how can you choose one for your business? We’ll take a look at four of the most popular platforms on the market.

What is SaaS PaaS IaaS

Software as a Service {SaaS} is a delivery model that allows applications to be hosted in the cloud and delivered to customers over the internet. Subscriptions are available. SaaS is not like traditional software licensing. Customers don’t have to buy anything upfront or maintain the app’s infrastructure.

SaaS software is developed, maintained, and charged by the cloud service provider. SaaS subscribers can still access the application(s) they subscribe to as long as they have a compatible client device, a web browser, a dedicated application, and an internet connection.

SaaS is one of the leading service models for cloud computing. It includes Infrastructure as a Service, Platform as a Service, and Desktop as a Service. IaaS refers to different infrastructures like servers and databases, and PaaS is for development tools and environments. SaaS is purely cloud-based software.

SaaS is closely related to DaaS. DaaS delivers virtual applications and desktops to end-users over the internet but is a bit more complex than SaaS. DaaS abstracts all applications while SaaS does not. This allows for a complete desktop experience through the cloud.

How SaaS model works

SaaS has both a financial and technical component.


SaaS, a cloud-based software hosted in a central location by the service provider, is centrally hosted in a data center. Most often, it is delivered in a multi-tenant architecture.

This means that a single configuration serves multiple customers and isolates their data from one another. Providers are responsible for maintaining the application’s security and updating it, and ensuring that customers receive it on time.

The end customer is not responsible for managing any operating systems, middleware, or runtimes associated with the application.

The internet allows you to access a SaaS solution. There may be both a web application and/or a downloadable (desktop/mobile) app, depending on which software is being used. Access is as easy as signing into an account with SaaS from any client.

However, organizations may use additional security measures like single sign-on and a specialized launcher to monitor SaaS activity.


SaaS software is subscription-based. Subscribers pay an ongoing fee for access to the software.

Instead of paying upfront for a license and then continuing to support it with on-premises infrastructure, SaaS is subscription-based software. SaaS, in other words, is an operating expense (OpEx) instead of capital investment (CapEx).

SaaS is attractive to companies that value flexibility and low-risk investments in their software. SaaS is often free of upfront costs and requires no management or procurement of any infrastructure.

SaaS solutions can easily be scaled up as organizations grow. Plus, they are constantly receiving new features and updates from the provider. SaaS can be used by both SMBs and enterprises.

SaaS security

SaaS can only be accessed via a web browser. IT also has limited visibility into user activity. There are no protections built in against SaaS that may contain malware. Secure access is essential with many SaaS applications integrated into daily workflows.

The following are some of the most popular options for SaaS security:

  • SSO: Access to SaaS applications can be centrally managed. This makes it easier to provision and decommission user accounts, as required.
  • Specialized embedded browsers: Applications may include controls for copy/paste, printing, and more, to prevent data exfiltration when using SaaS.
  • Web filters: A web filter is used to block malware and check for violations of policies. If necessary, it can launch an isolated browser that opens unknown URLs from outside the company network.
  • Analytics platforms: These solutions can analyze data about SaaS use, rank it, and take the necessary corrective actions, such as logging off a risky user.
  • Secure network accessibility: To protect SaaS-related network connections, firewalls, web gateways, and cloud access security brokers are all possible.
  • Security integrations and multifactor authentication (MFA: Connecting with services such as Okta or Active Directory helps to secure SaaS. Also, implementing MFA is a good idea.

Apart from security measures, SaaS migration preparations should also include careful planning. This should consist of knowing which workloads and data will need to be transferred, how the new cost model will work, and who should be involved during the transition.

Cloud computing and SaaS

Cloud-based services have been the talk of the tech world for a while now, and they’re finally becoming a reality. Cloud computing is quickly becoming popular for small businesses because it’s easy to implement and manage.

The definition of cloud computing varies by context. Cloud computing can be described as the concept of providing ubiquitous, easy and convenient network access to a resource pool of computing resources that can be configured (e.g. servers, networks, databases applications and services) that are quickly created and released with a minimum of effort from the management or interaction with service providers.

What is a cloud migration strategy?

A cloud migration strategy is an approach to moving data, applications, and infrastructure from one site to another. It also allows for the replacement or modification of existing cloud technologies. The SaaS offers one of the more straightforward cloud migration paths.

A SaaS solution can replace an on-prem application in a way that is more efficient. An example: A CRM platform on-premises might be replaced by a SaaS version hosted and maintained in the cloud.

The SaaS model has its benefits and drawbacks. Before you sign up, it is important to thoroughly evaluate the application, the SaaS solution, and the track record of service providers.

An organization may use additional cloud solutions in the IaaS or PaaS areas to rehost or refactor its business apps, in addition to the SaaS-driven cloud migrating.

Benefits and Risks of Cloud Software

SaaS allows customers to access software quickly and easily with minimal overhead.

SaaS includes hosted collaboration platforms for chat, video conferencing, expense management software, and customer relationship management solutions in the cloud. These all offer similar functionality or are easier to manage than traditional licensed counterparts.

SaaS has been the predominant method of using software in business and is now the largest cloud computing segment.

Most organizations have made SaaS adoption central to their cloud migration strategies to streamline access to critical applications and reduce licensing costs.

SaaS has some security issues due to the ease of app access. SaaS users can use a standard web browser to access an app.

This allows them to do whatever they like, without IT’s permission. It is crucial to balance SaaS convenience with security.

Advantages of SaaS and cloud applications

Customers can enjoy many benefits from putting applications in the cloud via SaaS, including consistent access to the most recent functionality and substantial cost savings.

#1 – Value creation takes less time

Cloud-based software is easy to get started. Once an organization has set up a SaaS subscription and implemented security controls, they can immediately start to use the business application and reap the benefits. Client apps can be used in many cases without any customization.

#2 – Scalability increases

SaaS solutions can easily be scaled up to multiple users without the need to create and maintain additional infrastructure. All that is required is an update to your subscription. Most SaaS solutions allow for multiple concurrent users to be supported by the service provider.

#3 – Lower costs

SaaS scales according to actual usage. Customers only pay for what they use. There is no risk of buying too many licenses or making significant CAPEX investments that will become a burden in the long term.

#4 – Remote work is more manageable and flexibility

SaaS apps are accessible via the internet and can be accessed easily from any device, mobile or desktop. These applications are ideal for remote work and provide consistent access from any device at any time.

#5 – Continual improvement

SaaS service providers continue to improve their offerings by adding new features and fixing problems.

It is usually as easy as restarting the SaaS application and confirming that a prompt has been given. Upgrade packages and specialized implementation services are not required.

How to invest in SaaS cloud

Before investing in SaaS, you should make two essential preparations:

  1. Select a reliable provider that offers a service-level agreement that is tailored to the needs of your organization.
  2. Reduce security risks associated with accessing business applications outside the company premises, in remote workspaces.

The cloud service provider does most of the security work, but the customer company still has to consider how to protect end-user access. Users are empowered by cloud-based software. They have complete control over where and how they access company data. This setup can increase security risks and lead to data breaches.
