1/8: Hey folks! Today, let's talk about Content Delivery Networks (CDNs) and their significance in the online world.
๐ CDN stands for Content Delivery Network, and it plays a vital role in ensuring fast and reliable content delivery to users around the globe. Let's dive in!
2/8: In simple terms, a CDN is a nw of servers strategically distributed across various locations worldwide. These servers store copies of websites, images, videos, and other web content. When a user requests this content, the CDN delivers it from the server closest to the user.
An IP (Internet Protocol) address is a unique numerical identifier assigned to devices on a network. It's like a phone number for your device on the internet. #NetworkingBasics
2/10: ๐ข IP addresses are divided into two main versions: IPv4 and IPv6.
IPv4 uses a 32-bit address format (e.g., 192.168.0.1),
while IPv6 uses a 128-bit address format
(e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). #IPv4#IPv6
Establish clear goals and objectives for your automation efforts. Define what success looks like and how it aligns with your organization's overall strategy.
2/10 โ๏ธ Adopt a toolchain:
Identify the right set of tools for your automation needs. Consider CI/CD platforms, configuration management systems, container orchestration tools, and monitoring frameworks. Choose tools that integrate well and meet your specific requirements.

Securing IAM Roles - Best Practices and Strategies
1/10: ๐งต Welcome to the world of AWS Roles! ๐
In this thread, I'll provide a detailed explanation of AWS Roles and share some examples to help you understand their significance in securing your AWS resources. Let's dive in! ๐ก
2/10: What are AWS Roles? ๐ค
AWS Identity and Access Management (IAM) Roles are a secure way to grant permissions to entities within or outside your AWS account. They enable you to define what actions can be taken on specific AWS resources by trusted entities.
Understanding the most important and critical part of AWS Identity and Access Management -
"The IAM Policies"
A Thread ๐
Hey Twitterverse!
Today, let's dive into the fascinating world of AWS Identity and Access Management (IAM) policies. IAM policies define permissions for AWS resources. Let's explore different types of IAM policies and see some examples. #IAM#AWS
1. First up, we have the "AWS managed policies." These are policies created and managed by AWS. They cover common use cases and are maintained by AWS to ensure compliance and security.
For example, "AmazonS3ReadOnlyAccess" allows read-only access to Amazon S3 resources.
