AWS Interview Questions for Freshers

1. What Is AWS?

The full form for AWS is Amazon Web Services. Offered by Amazon, it’s the most popular platform for cloud computing.

From database storage and developer tools to security, analytics, and IoT, it provides over 200 fully-featured remote services. The computing power and storage of the AWS servers are available as managed service on lease.

Among the different types of cloud computing serves, AWS relates to Infrastructure-as-a-Service (IaaS).

2. What Is Meant by Cloud Computing?

According to AWS, cloud computing refers to the delivery of on-demand IT resources through the internet on pay per use basis.

When you require technology services like databases, computing power, storage, etc., you reach out to a cloud provider such as AWS, which will provide you with cloud computing services on an as-needed basis.

This precludes the need to buy, own, and maintain your own servers and physical data centers.

3. Are You Aware of the Different Kinds of Services in Cloud Computing?

The only thing that’s constant in the tech sector is “change”, so it’s a wonder that cloud computing services keep evolving as well.

We now have a variety of cloud computing services designed to address different IT requirements. There three main types include:

Infrastructure-as-a-Service (IaaS)

Under this model, the provider offers hardware resources and will manage them for users, who get access to networking, data storage capacity, processing power, and other computing resources.

In other words, IaaS lets you utilize virtual machines or computing power with server management or labor-intensive hardware investments.

Your cloud provider will have servers and diverse networks distributed across data centers in multiple locations, from where you pull hardware resources.

Software-as-a-Service (SaaS)

This is the type of cloud computing service in which the cloud provider hosts software or applications on their servers and provides them to organizations or users on the lease, usually on a subscription basis.

Under this model, users access their desired application using a web browser. They’re provided with user credentials, including a username and password to log in to their account and begin using the application.

Among the most common software and applications leased as SaaS include CRMs, ERPs, email, calendaring, document management, and so on.

Platform-as-a-Service (PaaS)

PaaS providers not only provides an IT infrastructure to business or users but also allow them to develop their own applications.

Developers get a framework that they can use to build custom applications over the internet without having to worry about data serving, data storage, and management.

If you’re a web developer, you may lease the infrastructure you need for the complete application lifecycle, from the development and testing phase to deployment and maintenance.

When you sign up for a PaaS solution, you may expect host solutions, support, OS, server software, software tools for development and design, storage, environment for server-side scripting, network access, and DBMS.

4. How Is AWS Different from OpenStack?

While both OpenStack and AWS are cloud computing solutions, the former is an open-source infrastructure software project, while the latter operates under Amazon’s proprietary license.

When it comes to computing, users can upload their own images but, OpenStack comes with an IaaS infrastructure that scales horizontally on hardware without specified requirements.

AWS, on the other hand, has EC2 or virtual scalable networks with EMR and Xen Hadoop-based big data analytics.

On top of that, multiple other differences exist that relate to networking, identity, security, and storage associated with the two solutions.

5. What is AWS Global Cloud Infrastructure?

AWS provides cloud infrastructure to users around the world under the IaaS model, through which it offers storage, compute, virtualization, and networking services on a pay-as-you-go model.

Some important terms used in global cloud infrastructure include:

Edge Locations: These are AWS data centers created to deliver services at the lowest possible latency rates. Amazon’s numerous edge locations are located all over the world.

As opposed to Availability Zones and Regions, which are typically situated in major cities, edge locations are closer to users so as to ensure snappy and fast responses.

Region: It’s the section or subcontinent where Amazon’s Availability Zones are located that offer resources to customers in that area.

Availability Zones (AZs): AZs are locations or cities in Regions that host Amazon’s fully operational data centers offering cloud services to customers in those zones.

6. What Does AWS Offer Under Content Delivery and AWS Network Services?

 AWS’s offerings in content delivery and networking include:

Route 53: AWS Route 53 is a highly scalable Domain Name System (DNS) service intended to manage DNS for machines and services deployed on AWS public cloud.

It connects requests from users to infrastructure that runs on the AWS, including Amazon S3 buckets, ELB load balancers, and Amazon EC2 instances.

Virtual Private Cloud (VPC): This is an isolated, secure private cloud hosted in a public cloud. Customers can host websites, store data, run code, etc. in a regular private cloud, but which is remotely hosted in a public cloud.

This way, VPC combines the data isolation offered by private cloud computing with the convenience and scalability associated with public cloud computing.

Although a public cloud is packed with customers requiring computing resources, some of those resources will be reserved for you by the VPC.

7. What Are the Major Features of AWS?

The most prominent features of AWS include:

  • Compliance and Security
  • Data Transfer and Data Management
  • Visualization
  • Compute & Networking
  • Operations and Management
  • Storage
  • Automation and Orchestration

8. Why Is Buffer Critical to Amazon Web Services (AWS)?

The Elastic Load Balancer is designed to distribute the incoming traffic across different AWS instances optimally. A buffer is used to synchronize different components.  

With the buffer creating an equilibrium that links the different apparatus, the components that are otherwise prone to work in an unstable manner are crafted to work at an identical rate to deliver more efficient services.

9. What Are the Benefits of Using AWS?

Some of the benefits of leverage AWS include:

Availability of Managed IT Services

Managing an organization’s IT infrastructure is demanding and hectic.

Thankfully, AWS offers managed IT services, precluding the need for this critical obligation because you’re using Amazon’s infrastructure and not your own.

Running your business becomes remarkably easier as a result because AWS completely takes over the management part of the operation.

Robust Security and Encryption

Using AWS services also means that your systems, infrastructure, data, and everything else remain extremely safe. With over 38 AWS data centers worldwide, your private information and data are guaranteed to stay secure and safe.
