How can I get started with CloudWatch Synthetics?

Amazon CloudWatch gathers and monitors metrics, logs, and events from different AWS resources and applications. It offers a single view of your AWS resources and application performance, enabling you to identify issues in a hassle-free manner.

There is no single ""most in-demand"" DevOps tool, as the DevOps toolchain is made up of many specialized tools that are all in high demand. The most sought-after tools are foundational technologies and platforms that enable modern, cloud-native development practices, such as containerization, orchestration, infrastructure as code, and CI/CD pipelines.
Most in-demand DevOps tool categories

• Cloud computing platforms (AWS, Azure, GCP)

As businesses continue to migrate to the cloud, expertise in a major cloud platform is a foundational skill for any DevOps professional.

• Containerization and orchestration

Containerization standardizes how applications are packaged and run, while orchestration automates their deployment and management at scale.
Infrastructure as Code (IaC)
IaC is the practice of managing and provisioning infrastructure using code instead of manual processes, ensuring consistency and repeatability.

• CI/CD automation

Automating the Continuous Integration and Continuous Delivery pipeline is central to DevOps, enabling rapid and reliable software releases.

• Monitoring and observability

As systems become more complex, the ability to monitor application performance, collect logs, and trace errors is essential for maintaining reliability.

Git, Docker, and Ansible are generally considered the easiest DevOps tools to learn for beginners.
