With the expansion of technological innovations, the cloud service industry is also expanding. The most popular cloud computing category is SaaS application development. Well, SaaS is a developing industry with excellent career opportunities. Hence, the number of SaaS Development companies is expanding.
Now, the scope of the SaaS industry is attracting developers to work on SaaS projects. So, SaaS Application development companies are hiring developers. Today with this article, we will help developers by providing them with top SaaS-related interview questions and answers.
Let's start with the interview Q&As related to SaaS and the cloud computing industry.
1) What is SaaS?
SaaS is a web-based platform for software-as-a-service providers. The users can access the SaaS applications from web browsers. SaaS doesn’t need installation or manual setup. SaaS applications are accessible across the internet.
2) Give some examples of SaaS applications.
Famous examples of SaaS applications are Salesforce, Zoom, Slack, Canva, Shopify, Netflix, Hubspot, and many others. The brands themselves are proof of the SaaS popularity.
3) Why is SaaS so popular?
Nowadays, businesses can afford, access, and simplify software applications because of SaaS application development services. SaaS has many advantages. Hence, companies are adapting SaaS application development for a new business model. As you are aware, SaaS is managed and hosted by cloud computing services, which means SaaS privileges come with several benefits.
4) Describe three types of cloud computing models.
Public, private, and hybrid cloud computing models are the three different categories.
Public cloud: A third-party service provider owns and runs public clouds, which make their resources accessible to everyone.
Private clouds are not accessible to the general public and are owned and run by a single company.
Hybrid cloud: Organizations can employ both internal and external resources via hybrid clouds, which combine public and private clouds.
5) Differentiate between IaaS, PaaS, and SaaS.
Of all the three categories of cloud computing, IaaS stands for Infrastructure-as-a-Service, which provides users with virtual storage and virtual machines. PaaS stands for Platform-as-a-Service, where the users have access to a runtime environment (for the creation and use of tools and applications). SaaS stands for Software-as-a-Service, allowing end users to access all of their services, such as storage, application hosting, and others.
6) How do you interpret multi-tenancy in the context of SaaS?
SaaS is a multi-tenant application. SaaS applications offer a single instance that serves various tenants. With isolated data and configurations, each tenant, in other words, gets their private area within the program.
7) What benefits do SaaS models have over alternative cloud-based approaches?
In the competition of cloud computing approaches, SaaS is leading in the market. SaaS benefits from a pay-per-use pricing model. SaaS applications are scalable, flexible, and smoothly run on the web browser. Also, SaaS applications have prominent security and compliance.
8) What are APIs?
APIs are called Application Programming Interfaces, an API is a set of functions that allow the software to interact with others. This can involve just showing data on a screen, transmitting data to a web server, or retrieving data from a database. Software programs may communicate with one another and share data in large part because of APIs.
9) Could you provide me with any examples of practical uses that interact with third-party services via APIs?
Many web applications showcase third-party interaction services via APIs. For example “Semrush” is a web application that provides digital marketing services and uses third-party APIs to schedule various posts for social media platforms like Facebook, Twitter, LinkedIn, etc.
10) What are the primary concerns when developing an API?
The concerns that may haunt us while developing an API are security, performance, and scalability.
11) Describe RESTful architecture.
Software that makes use of the web is designed using a RESTful architecture. It is founded on the notion that resources have unique IDs known as uniform resource identifiers (URIs). Several common techniques, including GET, POST, PUT, and DELETE, can be used to manipulate these resources.
12) Give five examples of SaaS cloud service providers.
Here, are the five big cloud services provided Microsoft Azure, Oracle Cloud, SAP, Salesforce, and Dropbox.
Here, closing with the conclusion that the above questions and answers are related to SaaS application development which may help developers for the interviews. Many SaaS development companies are hiring developers to join them and work on challenging projects.
