Agenda for Today

Today, we will cover several key topics:

1. Understanding what cloud computing is.

2. Comparing public cloud and private cloud.

3. Exploring the popularity of public cloud platforms like AWS, Azure, and GCP.

4. Discussing why AWS stands out among other cloud platforms.

5. Addressing the trend of cloud repatriation.

6. Creating an AWS account for practical learning.

What is Cloud Computing?

To grasp the concept of cloud computing, we need to look back at how organizations managed their IT infrastructure in the past. Traditionally, companies would purchase physical servers from providers like IBM or HP and set up their own data centers. A data center is a facility that houses servers and the necessary infrastructure to support them, including networking, cooling, and power management.

However, this approach has significant drawbacks. For instance, if a company buys a server with 100 GB of RAM and 100 CPUs but only runs an application that uses 1 GB of RAM and 1 CPU, the remaining resources are wasted. To address this inefficiency, the concept of virtualization was introduced. Virtualization allows multiple virtual servers to run on a single physical server, optimizing resource usage.

Public Cloud vs. Private Cloud

Private Cloud

In a private cloud, the infrastructure is maintained and managed within an organization. Only that organization has access to the resources, ensuring greater control and security. Companies with sensitive data, such as banks, often prefer private clouds to maintain strict security protocols.

Public Cloud

Conversely, public cloud services are offered by providers like AWS, Microsoft Azure, and Google Cloud Platform (GCP). These providers manage the infrastructure and resources, allowing anyone with an account to access and utilize them. This model is beneficial for startups and mid-sized companies that may not have the resources to maintain their own data centers.

Why is Public Cloud Popular?

Public cloud platforms have gained immense popularity for two main reasons:

1. Cost Efficiency: Organizations can avoid the high costs associated with purchasing and maintaining physical servers.

2. Reduced Maintenance Overhead: By leveraging public cloud services, companies can focus on their core business activities rather than managing IT infrastructure.

AWS, for example, started with a limited number of services but has since expanded to offer over 200 services, making it a comprehensive solution for various business needs.

Why AWS is a Leading Cloud Provider

AWS is particularly popular for several reasons:

1. First-Mover Advantage: AWS was one of the first cloud service providers, establishing a strong market presence and gaining a large customer base.

2. Wide Adoption: Many companies began their cloud journey with AWS, leading to a network effect where new companies prefer AWS due to its established reputation.

3. Job Opportunities: As AWS holds a significant market share, there are more job openings for AWS-skilled professionals compared to other cloud platforms.

Addressing Cloud Repatriation

Recently, there has been discussion about cloud repatriation, where some organizations are moving back from public cloud services to on-premises solutions. However, this trend is minimal, with only about 1-2% of users making this transition. The majority of organizations continue to adopt public cloud services due to their scalability and cost-effectiveness.

Creating an AWS Account

To start our journey with AWS, we need to create an AWS account. Here’s a step-by-step guide:

1. Open your preferred web browser and search for "AWS sign in."

2. Click on "Create a new AWS account."

3. Enter your email address and choose a password.

4. Provide your account name and verify your email address.

5. Fill in your personal details, including your phone number and address.

6. Enter your credit or debit card information for account verification (AWS will not charge you directly).

7. Complete the account setup process.

Once your account is created, we will use it throughout this series to explore various AWS services.
