AWS Management

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?

Networking

What is Networking?

Computer Networking is the subject which explains how computers connect with each other for sharing resource and information and what technologies and devices they use for the coonectivity.

Three components of networking

• Medium ( How are you connected? )
• Addressing ( How do you locate and identify the other party? )

MERN Stack

The MERN stack consists of the following technologies:

• MONGODB: A document-based open source database.

• Express: A web application framework for Node.js

• React: A JavaScript front-end library for building user interfaces.

• Node.js: JavaScript run-time environment that executes JavaScript code outside of a browser ( such as a server)

  and Mongoose: Simple, schema-based solution to model application data.

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."

Time Series

• A set of values measured sequentially in time
• Values are typically (but not always) measured at equal interval x₁, x₂, x₃, etc..
• Values can be:
  • Continuous
  • discrete or symbolic (words)
• Associated with empirical observation of time varying phenomena:
  • Stock market price (day, hour, minute, tick etc...)
• Temperature (day, minute, second, etc..)

Think DSP

1. Discrete Fourier Transofrm
2. Convolution Theorem
3. Linear Time-Invariant Theory

Signal: It represents a continuous mathematical function

Wave: Contains an array of discrete samples
