Intro to AWS VPC

AWS VPC or Amazon Virtual Private Cloud is a service that enables customers to launch their AWS resources in a virtual network that is logically isolated from other networks in the AWS cloud, and in some cases, even from the internet. When creating a VPC, customers can define their own IP address range, subnets, and route tables, and have full control over their virtual network topology. They can also configure security groups and network ACLs to control access to their resources, and use a variety of network connectivity options, such as virtual private network (VPN) or AWS Direct Connect, to securely connect their VPC to their on-premises data centers or other networks.

DynamoDB and DAX


DAX (DynamoDB Accelerator) is a fully managed, in-memory caching service for DynamoDB that can significantly improve read performance by reducing the number of requests to DynamoDB. DAX is designed to work with DynamoDB, and it provides a fast, scalable, and highly available caching layer that sits between your application and DynamoDB.

DAX can significantly improve read performance by reducing the number of requests to DynamoDB and caching frequently accessed data in memory. By using DAX, you can improve the performance and cost-effectiveness of your application while minimizing infrastructure management.

Intro to AWS Region

AWS Region is a physical location where AWS maintains multiple data centers that are interconnected by a low-latency network. Each region is a separate geographic area, identified by a unique name and code, such as us-east-1 or eu-west-2. AWS Regions are strategically located in different parts of the world to provide customers with a wide selection of geographic locations for hosting their resources, applications, and services. Each AWS Region consists of two or more Availability Zones (AZs), which are physically separate data centers located within a single region. Each AZ is designed to be highly available and fault-tolerant, with independent power, cooling, and networking infrastructure. Continue reading "Intro to AWS Region"

Intro to AWS DynamoDB

AWS DynamoDB is a fully managed NoSQL database service provided by Amazon Web Services (AWS). It is a high-performance, scalable, and highly available database that can handle millions of requests per second and can automatically partition and re-partition data across a cluster of machines.

DynamoDB allows you to store and retrieve any amount of data and serve any level of request traffic, and provides a flexible and efficient data model that supports both document and key-value store paradigms. It also offers advanced features such as automated backups, global replication, and fine-grained access control.

Intro to AWS Serverless

AWS Serverless is a cloud computing model in which the cloud provider (AWS) manages the infrastructure and automatically provisions, scales, and manages the computing resources required to run an application. In a Serverless architecture, the customer only pays for the actual usage of the application, rather than paying for fixed computing capacity. AWS Serverless computing is based on the concept of functions as a service (FaaS). A function is a self-contained piece of code that performs a specific task, such as processing data or responding to an event. The AWS Lambda service is a FaaS service that allows developers to write and deploy functions in a variety of programming languages, including Java, Python, Node.js, C#, and more.

Intro to Cloud Computing and AWS Cloud

What is Cloud Computing

Cloud computing is a model for delivering computing resources over the internet. Instead of relying on local hardware and software to perform tasks, cloud computing allows users to access computing resources such as servers, storage, databases, applications, and other services over the internet on an as-needed basis.

With cloud computing, users can access computing resources on demand, pay only for the resources they use, and scale resources up or down quickly and easily. Cloud computing also offers a high level of flexibility and mobility, allowing users to access their applications and data from anywhere with an internet connection, on any device.

Intro to AWS S3

What is Amazon S3?

Amazon Simple Storage Service (S3) is a cloud-based object storage service provided by Amazon Web Services (AWS). S3 provides scalable storage for any type of data, including images, videos, audio files, text documents, and more.

S3 offers a highly available and durable platform for storing and retrieving data. It also offers features like versioning, server-side encryption, lifecycle policies, and cross-region replication. With S3, you can store and retrieve data from anywhere in the world, using a simple web interface, command line tools, or APIs.
