Introduction
This module, presented by Peter Vandaele, introduces the foundational concepts of cloud computing and the benefits of using AWS. He covered the essential characteristics of cloud computing, the differences between traditional on-premises infrastructure and cloud-based solutions, and the economic advantages of using cloud services.
Most Important Learning Highlights from Module 1✨
🔶Definition of Cloud Computing
Cloud computing delivers IT resources over the internet on a pay-as-you-go basis. This allows businesses to access services like computing power and storage without investing in physical hardware. It enables quick deployment and scaling of applications, optimizing IT costs.
🔶Advantages of Cloud Computing
Cloud computing offers cost savings, agility, and access to various services. Businesses avoid upfront hardware costs and only pay for what they use. This model supports rapid deployment and scaling, enhancing responsiveness and innovation.
🔶Types of Cloud Computing
Cloud computing includes Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides basic computing resources, PaaS offers a platform for building applications, and SaaS delivers software over the internet. AWS offers solutions across all three types.
🔶AWS Global Infrastructure
AWS operates data centers worldwide, divided into regions and availability zones. This setup ensures high availability, low latency, and reliable performance. AWS's global reach helps businesses deploy applications close to users and maintain data resilience.
🔶Economic Benefits
Cloud computing eliminates the need for expensive hardware and reduces ongoing IT costs. Businesses pay only for the resources they use, aligning expenses with actual needs. AWS also provides tools to help manage and optimize spending.
🔶Security in the Cloud
AWS offers a secure environment with features like encryption and identity management. AWS meets stringent security standards, protecting customer data. The infrastructure includes robust physical and network security measures.
🔶AWS Shared Responsibility Model
AWS and customers share security responsibilities. AWS secures the cloud infrastructure, while customers manage security within the cloud, such as data and application configurations. This model ensures flexibility and control for customers.
🔶Elasticity and Scalability
AWS allows businesses to scale resources up or down quickly based on demand. This ensures efficient resource use and cost savings. Services like EC2 Auto Scaling help maintain performance and availability without overprovisioning. We have already explored this topic in detailed in Day 19: High Availability🔁& Scalability♾ in AWS☁
🔶AWS Service Categories
AWS offers a variety of services in compute, storage, database, networking, and more. These services enable businesses to build, deploy, and manage applications effectively. AWS continuously expands its offerings to meet diverse needs.
🔶AWS Pricing Models
AWS provides flexible pricing options like pay-as-you-go, reserved instances, and spot instances. This flexibility helps businesses optimize costs based on their usage patterns. AWS also offers tools to manage and control spending. We have already explored this topic in detailed in Day 8: EC2 Budget Setup💰📝
