AWS (Amazon Web Services) is a cloud computing platform that provides a wide range of infrastructure services such as servers, storage, databases, networking, and more. It is primarily used by developers, IT teams, and businesses to build, deploy, and scale applications and services across the globe.

Salesforce, on the other hand, is a cloud-based Customer Relationship Management (CRM) platform. It is designed to help businesses manage customer interactions, sales pipelines, marketing efforts, and customer support operations through a suite of integrated business applications.

The core difference lies in their purpose and target users. AWS focuses on offering the foundational infrastructure for various IT needs, making it ideal for technical professionals and developers. Salesforce is geared toward business users who need tools to manage customer relationships and drive sales and marketing processes.

In summary, AWS powers IT infrastructure, while Salesforce powers customer relationship management.

Yes, AWS can be a good choice for a fresher, especially if you're interested in cloud computing, DevOps, or backend development. It offers a wide range of beginner-friendly resources, including free-tier services, certifications (like AWS Certified Cloud Practitioner), and hands-on labs.

Starting with AWS helps you build practical skills in cloud infrastructure, which is in high demand across industries. However, it’s important to have a basic understanding of networking, Linux, or programming to make the most of it.

Yes, the AWS DevOps Engineer – Professional certificate is worth it if you're aiming for a career in cloud DevOps or infrastructure automation.

It validates advanced skills in CI/CD, monitoring, security, and managing scalable systems on AWS—skills highly valued in cloud and DevOps roles. It can boost your resume, increase job opportunities, and often leads to higher salaries.

However, it's an advanced-level certification, so it’s best pursued after gaining hands-on AWS experience and completing at least one associate-level cert (like AWS Solutions Architect or Developer).

AWS EBS (Elastic Block Store) is a block storage service provided by Amazon Web Services (AWS) that is designed to be used with Amazon EC2 (Elastic Compute Cloud) instances. It provides persistent, high-performance, and low-latency storage volumes that can be attached to EC2 instances, similar to how you’d attach a hard drive to a computer.
