Software Architecture

        > with Neil Ford & Mark Richards

Architecture is the highest level concept of the expert developers.

"In most successful software projects, the experts developers working on that project have a shared understanding of the system design. This shared understanding is called 'architecture'. This understanding includes how the system is divided into components and how the components interact through interfaces. These components are usually composed of smaller components, but the architecture only include the components and interfaces that are understood by all the developers."

Logging in the Cloud

Logging provides visibility into your cloud resources and applications. For applications that run in the cloud, you will need access to logging and auditing services to help you proactively monitor your resources and applications.

Logging allows you to answer important questions like:

• How is this server performing?
• What is the current load on the server?
