What is SaaS? Everything you need to know

Under the software as a service (SaaS) model, programs are hosted by a cloud provider and made accessible to end users over the internet

With the advancement of technology, several products have been launched across sectors, and with that, tech industry has witnessed an impressive growth. Among various new things Software as a Service (SaaS) has gained popularity over the years.

According to a McKinsey & Company report, the global SaaS market was worth about $3 trillion a few years back, and the estimates indicate that it could surge to $10 trillion by 2030.

Understanding SaaS

Under the software as a service (SaaS) model, programs are hosted by a cloud provider and made accessible to end users over the internet. In this case, the application’s hosting may be outsourced to a third-party cloud provider by an independent software vendor (ISV). Alternatively, the software seller could be the cloud provider in the case of major corporations like Microsoft. Along with platform as a service (PaaS) and infrastructure as a service (IaaS), SaaS is one of the three primary categories of cloud computing. SaaS apps are used by a variety of corporate and personal customers as well as IT experts. Products range from sophisticated IT solutions to personal entertainment like Netflix. SaaS solutions are often offered to both B2B and B2C consumers, in contrast to IaaS and PaaS.

Advantages of SaaS

SaaS removes the need for organizations to install and run applications on their own computers or in their own data centers. Businesses can no longer install and operate apps on their own PCs or in their own data centers thanks to SaaS. This lowers the cost of purchasing, procuring, and maintaining hardware. Also, the cost of installing, licensing, and providing support for software. Additional advantages of the SaaS model consist of:

Flexible payments: Customers subscribe to a SaaS solution rather than buying gear to support it or software to install. Many firms can practice enhanced and more consistent planning by converting expenditures to a recurrent operational expense. Additionally, users can stop paying such recurring fees at anytime by terminating SaaS offerings.

Scalable usage: High vertical scalability is a feature of cloud services like SaaS that allows users to access more or less features or services as needed.

Automatic updates: Customers can rely on a SaaS provider to handle patch management and updates automatically rather than buying new software. This reduces the workload for internal IT workers even further.

Accessibility and resilience: Users can access SaaS vendors apps from any place or device with internet connection as they get distributed over the internet.

Personalization: SaaS apps can be connected with other business apps and are frequently customizable, especially when they are created by the same software provider.

Disadvantages of SaaS

SaaS has some challenges and risks. It requires organizations to rely on outside providers for software provision, maintenance, correct billing tracking and reporting. Also, the facilitation of a safe environment for the company’s data. There are some more potential risks and issues associated with SaaS below:

Issues beyond customer control: Issues can arise when service providers face failures, force unwanted alterations to their service portfolio, or suffer a security breach. These events can significantly impact the SaaS offering’s use by clients. Customers should be aware of their SaaS provider’s SLA and ensure that it adheres to in order to proactively reduce these risks.

Clients are no longer in charge of versioning: In the event that the provider delivers an updated version of an application, all of its clients will receive it, whether or not they need the latest version. The company might need to allocate more time and funds for training as a result.

Having trouble switching vendors: It might be challenging switching vendors, just as with any other cloud service provider. Customers have to shift massive volumes of data in order to switch vendors. The usage of proprietary technologies and data formats by some vendors can also make it more difficult for customers to transfer their data between cloud providers. When a consumer is unable to switch service providers due to these circumstances, it is known as vendor lock-in.

Security: One major issue that SaaS applications frequently face is cloud security.

How does SaaS works

Software as a service (SaaS) is created by a vendor and licensed by a client. The software product that the vendor creates helps a business address an issue. Usually, it is constructed in a way that benefits clients by enabling scalability and requiring less maintenance. Clients then pay for the program over time (sometimes as a subscription), knowing that their feedback will eventually lead to improvements. In return for not having to worry about maintaining the software, the client does not own it.

SaaS vendors and examples

There are many different software vendors and products in the SaaS industry. The companies in the industry range from little vendors of a single product to massive cloud providers like Google and AWS.

SaaS offerings are similarly varied, encompassing anything from IT business analytics tools to video streaming services. Basic corporate functions including email, sales management, customer relationship management (CRM), financial management, human resource management (HRM), billing, and collaboration are all available as software as a service (SaaS). Vertical SaaS products are enterprise SaaS solutions designed for certain industry, like insurance or medicine.

SaaS solutions may be sold mainly to B2C, B2B, or both sectors. Popular SaaS product examples are as follows:

Salesforce
Google Workspace apps
Microsoft 365
HubSpot
Trello
Netflix
Zoom
Zendesk
DocuSign
Slack
Adobe Creative Cloud
Shopify
Mailchimp

SaaS vs IaaS vs PaaS: What is the difference?

Software-as-a-Service (SaaS): When it comes to SaaS solutions, customers are not in charge of overseeing IT infrastructure or handling any part of software management. Use Spotify or Netflix.

Platform-as-a-Service (PaaS): These tools give internal developers a platform to build personalized apps. The enterprise host or a third-party vendor can handle all server and storage administration while developers retain control over the apps they create. Two well-known PaaS offerings are Heroku and AWS Elastic Beanstalk.

Infrastructure-as-a-Service (IaaS): These products, which stand for Infrastructure-as-a-Service (IaaS), are utilized by companies looking to outsource their computer or data center operations. Hardware for networking, storage, and servers is hosted by IaaS providers. IaaS users are still in charge of their operating systems and data use. This is where cloud services can be accessed by companies thanks to technologies like Microsoft Azure and AWS. Even though the consumer could have a Netflix membership, Netflix might have a separate agreement with an IaaS provider.
