SaaS model stands for Software as a Service. It is a distribution mechanism for end users planning to introduce new software into their computing system. SaaS technology in cloud computing is one category of cloud computing systems.

The other two categories are infrastructure as a service (IaaS) and platform as a service (PaaS). IaaS, PaaS, Saas are thus three pillars of the cloud computing system.

What is Software as a Service (SaaS)?

The concept of SaaS has been around for the last few years. SaaS refers to Software as a Service, which is an alternative way of accessing software as opposed to the on-premise software. It is a subscription-based model, where the software is hosted in a virtual server known as the Cloud.

SaaS Solutions can be accessed on any device with a web browser and internet connection. It is different from on-premise software which is installed in the system. Companies don’t have to invest in hardware to host the software, the SaaS vendor takes care of all the IT responsibilities needed to maintain the software.

What is SaaS in Cloud Computing?

Cloud computing systems have SaaS software (Software as a service) as their key integral part. SaaS permits users to take a subscription for software or an application thus saving them from the hassle of purchasing it. You can also rent such software through SaaS applications.

Installation costs and maintenance charges get automatically reduced through SaaS technology. SaaS companies install, operate, and maintain specific types of software or applications on behalf of the company.

SaaS as a software distribution model makes applications available on the internet across all major categories, be it infrastructure as a service (IaaS), platform as a service (PaaS) or software as a service (SaaS).

Iaas PaaS Saas in cloud computing are three services providers that provide benefits and capabilities to their targeted users based on their core components. The core features that distinguish IaaS Paas SaaS cloud from each other have been enlisted below:

  • IaaS

IaaS or Infrastructure as a Service is a self-service model meant to access, monitor and manage data center infrastructures that are remotely situated.

This model offers services on an outsourced basis for strengthening computer infrastructure, such as, storage, networking, and virtualization. IaaS provides cloud-based alternative solutions to on-premise infrastructure.

Examples of IaaS: CISCO Metapod, Amazon Web services (AWS), Microsoft Azure, Joyent and Google Compute Engine (GCE).

  • SaaS

SaaS in cloud computing is a software distribution model that allows its end users to use cloud-based applications over the internet. SaaS products are launched by SaaS companies at their data center and customers access it through their browsers.

SaaS model is widely used for managing customer relationships, service desk, accounting, documents, and content management.  

Examples of SaaS platforms: SaaS Hoogle apps, Cisco WebEx, Dropbox, Concur, Salesforce and GoToMeeting.

  • PaaS

PaaS or Platform as a Service is used by developers who specialize in software or application development. PaaS platforms are based on virtualization technology. They are also scalable in nature.

PaaS vendors host hardware and software on their own infrastructure and can be used by end-users anywhere and anytime for the application development.  PaaS supports multiple users and is a preferred choice for businesses focused on developing unique applications.

Examples of PaaS: AWS Elastic Beanstalk, Apache Stratos, OpenShift, Heroku, Force.com and Google App Engine.

Challenges of SaaS Technologies

If not handled properly, SaaS can pose certain challenges to an organization in the long run. It is imperative to understand and analyze your business requirements before opting for a SaaS solution.

  • Unreliable Internet Connection: If your internet is strong, then there is nothing better than a SaaS cloud application. But if it fluctuates, it can be the biggest con. Although with high-speed internet and 5G connections available all around, this has become less of an issue.

  • Less Control: A SaaS application is completely managed by a third-party vendor. Even with the customizations offered to the user, the complete control still lies in the hands of the vendor only. In this case, the user may not get 100% of the desired features.

  • Security Risks: In SaaS, everything is managed and controlled by the vendor, which means even your confidential and sensitive data lies with them. Although the SaaS provider offers security, but you need to take a few actions from your end to secure your data.

  • Selecting The Right Subscription Plan: While trying a new application, we often select a monthly plan, which we may look cost-effective initially, but it is expensive in the long run. If you know the application will be used for more than a year, then it is cost-effective to choose an annual plan, otherwise there are options for a 6-month or 3-month plan.

  • Integration Issues: Wrong integration can cause a lot of trouble for your business. For example, if there are issues with billing, wrong invoices can be generated. It is imperative to have the sync of data between SaaS and other applications. Integrations are highly expensive and might require specialized IT professionals. So, you need to make sure that your SaaS application provides open APIs for seamless integration.

  • SaaS Saturation: With thousands of options available in the market, it is impossible for any IT team to select the right SaaS application. You can always go with recommendations and referrals but what can really help you are online reviews; they are unbiased and will always give you a clear picture.

  • Hybrid Infrastructure: When your on-premises or existing software work with cloud-based software like SaaS, it becomes a hybrid infrastructure. SaaS providers and your in-house IT team need to collaborate for integration, or you can hire a cloud consulting firm to do the work for you. Make sure that you take all the benefits of hybrid technology.

The Future of SaaS: Latest SaaS Trends

Well, everything in the future will ultimately come onto the cloud, and SaaS is just the beginning of it. The latest trends tell us that SaaS is here to stay for a long time!

  • Artificial Intelligence (AI): The AI industry has seen some significant developments in 2021 and is now predicted to become a market of $733.7 Billion by 2027. When AI capabilities are combined with SaaS, it can do wonders for businesses. Together, both have a great shining future ahead. AI can help SaaS become more personalized, speedy, secure and data intelligent.

  • Vertical SaaS: Vertical SaaS is completely customizable and focuses on targeting clients in a specific niche or industry like healthcare, logistics, or retail analytics. It helps organizations find a solution that is specific and specially designed to cater to their needs. It provides more business value, ensures industry-specific data governance and is cost-effective.

  • MarTech Trend: Marketing BI and data analytics are even letting non-graphic designers fulfill their needs for better branding and campaign management. Canva is one of the most popular examples of MarTech that offers free trials and easy billing which makes it accessible to small businesses as well.

  • Low-Code Platforms: No one wants to spend hours coding when developers have the option to build applications and websites with low-code platforms. This creates opportunities for many non-coders to join the SaaS industry. They can use visual programming, which is almost like drag, drop and create. This will not only bring more people to the SaaS industry but will also bring new application options to the market.

  • Migrating to PaaS: After customer acquisition, developers will now focus on customer retention, which will lead to the migration to PaaS. This will help startups in scaling up. For example, an app can scale up geographically by using the tools on AWS to gain an edge over their competitors.

    With all these services and customizable options, migration to SaaS ensures that business owners just focus on the creative and commercial part of their business, and the cloud computing technicalities are handled by experts.
