Study Notes

Multiple Topics

Cloud Computing Basics

Cloud computing refers to the delivery of computing resources over the internet, enabling users to access shared pools of computers, servers, databases, and applications without having to manage their own hardware or infrastructure. Cloud computing offers several benefits such as cost savings, flexibility, scalability, and ease of deployment.

AWS Fundamentals

Amazon Web Services (AWS) is one of the leading cloud service providers that offers various services such as compute, storage, database, and analytics. AWS provides infrastructure services like Amazon Elastic Compute Cloud (EC2), which enables users to rent virtual computers on which they can run their own applications. They also offer machine learning services like Amazon SageMaker, which allows users to build, train, and deploy machine learning models quickly. AWS uses the concept of infrastructure as code (IaC) using tools like AWS Cloud Development Kit (CDK) that allow developers to model their applications in programming languages instead of domain-specific ones, leading to easier application deployment and maintenance. They also provide services through APIs such as AWS Management Console and AWS Command Line Interface (CLI) for managing resources programmatically.

Network Programming Language Basics

Network programming involves writing software that communicates over a network, either between different machines or within a single system. Programming languages play a crucial role in network programming due to their expressiveness and ability to handle complex tasks efficiently. Some popular programming languages for network programming include Python with libraries like sockets, requests, and Beautiful Soup; Ruby with its net/http library; and Java with its java.net package. These language choices depend on factors such as performance requirements, ease of use, and compatibility with existing codebase.

Linux Basics

Linux is an open-source operating system based on Unix principles. It's widely used in servers, supercomputers, and embedded devices. The main reason behind its popularity is its stability, flexibility, and security features. Linux distributions are freely available, and their source code can be modified by developers worldwide, making them suitable for both personal and professional use. Some common Linux distributions include Ubuntu, Fedora, CentOS, Debian, and Arch Linux.

SQL Basics

Structured Query Language (SQL) is a standard language for managing relational databases. It was developed by IBM in the early 1970s. Today, SQL is supported by most relational database management systems (RDBMS). SQL consists of two parts: declarative statements called SELECT, INSERT, UPDATE, and DELETE statements, and procedural statements called CREATE PROCEDURE and CALL statements. SQL is primarily used for manipulating and retrieving data from relational databases, including performing queries, updating data, defining views, and creating stored procedures.
