AWS Zero to Hero Series - Episode 1

Introduction

  • Speaker: Abhishek
  • Series: 30 days of AWS focusing on DevOps engineering
  • Goal: Gain foundational knowledge of AWS and public cloud to apply in projects or as an AWS DevOps Engineer

Agenda

  1. Understanding what the cloud is
  2. Comparing public cloud and private cloud
  3. Popularity of public cloud platforms (AWS, Azure, GCP)
  4. Why AWS stands out among other cloud platforms
  5. Discussion on the trend of moving back to on-premises from public cloud
  6. Creating an AWS account for hands-on practice

What is Cloud?

  • Traditional Method: Organizations purchased servers from companies like IBM or HP and built data centers.
    • Setup includes servers, networks, temperature control, etc.
    • Costly and often resulted in underutilized resources.
  • Virtualization: Created virtual servers (virtual machines) on physical servers to optimize resource use.

Introduction to Cloud Computing

  • Public Cloud vs Private Cloud:
    • Public Cloud: Managed by third-party providers (AWS, Microsoft Azure, Google Cloud).
    • Private Cloud: Managed internally by an organization.
  • Advantages of Cloud:
    • Reduced maintenance overhead for startups and mid-sized companies.
    • Cost-effective, pay-as-you-go model.
  • Popular Services: Virtual machines (EC2 instances), storage, databases, etc.

Why Public Cloud is Popular

  1. Ease of Onboarding: Reduced complexity and overhead of managing physical data centers.
  2. Cost: More affordable, especially for startups and mid-sized companies.
  3. Maintenance: Providers handle upgrades, security, and scaling.
  4. Service Variety: From virtual machines to managed Kubernetes services.

AWS Specifics

  • First Mover Advantage: AWS pioneered the cloud market, gaining a significant market share.
  • Market Penetration: More job opportunities as many companies use AWS.
  • Service Expansion: Over 200+ services including compute, storage, databases, etc.

Cloud Repatriation

  • Trend: Some organizations are moving back to on-premises (private cloud).
  • Reasons: Security concerns, cost optimization, operational control.
  • Impact: Minimal, only about 1-2% of companies moving back.

Creating an AWS Account

  1. Steps:
    • Go to AWS sign-in page and create a new AWS account.
    • Provide email, root user credentials, and personal details.
    • Verify email and create a password.
    • Set up billing information using a credit/debit card.
    • Complete the setup with tax information (if required).
  2. Usage: The account will be used for the next 30 days of AWS learning.
  3. Cost: Pay attention to AWS Free Tier limits to avoid unexpected charges.
