Day 9 of EDL focuses on the integration of cloud computing and DevOps.

When it comes to networking, private and public servers are like two sides of the same coin. But trying to navigate the Transit Gateway is like finding your way through a maze of internet access and security concepts. As you create and modify access policies and permissions, it’s like cracking a code to access the heart of the servers. It’s a wild ride that requires careful navigation and a touch of creativity. Stay sharp, folks! ๐Ÿš€๐Ÿ”’

### Key Takeaways ๐Ÿ“š
– Cloud computing and DevOps were discussed on Day 9.
– Important concepts such as Transit Gateway, VPC, identity management, and AWS services were covered.
– The role of policies in granting permissions and managing user access was explained in detail.

#### ๐Ÿ–ฅ๏ธ Networking and Access Controls
While discussing cloud computing and DevOps on Day 9, networking and access controls were the main focus. We looked at Transit Gateway, VPCs, and services network, as well as the concept of identity management, which is a critical part of corporate AWS services. We also delved into user credentials and their usage, including the creation of users, groups, and policies.

#### ๐ŸŒ Understanding Security and Permissions
The emphasis was on security credentials and permissions, covering access configurations to manage user activities. Through the use of security credentials, we learned how to configure, grant, and restrict access to selected resources, and the limitations of different types of access permissions for actions.

| Networking infrastructure and access controls were key |
| Security credentials and effective access configurations |

#### Forming and Managing Policies and Users
Understand that it is pivotal to control access to resources securely. Different policies can be created to selectively grant and limit access to services such as S3. The focus was also on understanding the intricate concepts of IAM and creating roles with the right permissions attached.

#### Understanding Credentials and Permissions
Troubleshooting access policies and user permissions through modifications and deletions formed the core of the discussion. There was also an in-depth explanation on how to control and monitor user access effectively.

| Overall access trial with IAM and permission allocation |
| Access policy control and monitoring user activity |

With these key takeaways in mind, our understanding of cloud computing, networking, security, and user permissions has significantly deepened. This knowledge is foundational for effectively managing systems and user access in cloud and DevOps environments.
