The key difference lies in the relationship structure. The Observer pattern involves a one-to-many relationship, while Publisher-Subscriber involves a many-to-many relationship between publishers and subscribers.

When migrating to the cloud, it's essential to implement cloud-native monitoring and logging solutions. These tools are optimized for cloud environments, providing better visibility, scalability, and integration capabilities. Continuing to use on-premise tools may not adapt well to the dynamic cloud environment. Relying solely on the cloud provider's default monitoring services may lack customization. Disabling monitoring during migration poses a risk of missing crucial insights into performance and issues.

The command "git bisect" is used for incremental debugging in Git. It helps locate the commit that introduced a bug by performing a binary search through the commit history. Developers mark good and bad commits, and Git efficiently narrows down the problematic commit.

The split() method is used to split a string into an array of substrings based on a specified delimiter. It does not create objects, characters, or elements, but rather substrings.

Deadlock is a phenomenon in which two or more transactions are waiting indefinitely for resources held by each other, leading to a state where none of the transactions can proceed. It is a critical issue in concurrent systems and requires careful handling to avoid system gridlock.

Infrastructure as Code helps in achieving rapid infrastructure deployment. By defining and managing infrastructure through code, deployment becomes faster, more consistent, and scalable.

Azure App Service is recommended for deploying a web application with high availability. It offers automatic load balancing, geographic distribution, and scaling capabilities to ensure high availability and performance.

Software requirements are documented in the Requirements Definition phase of the SDLC. This phase involves specifying what the software should do and defining the features and functionalities it needs to have.
