Getting Started with AWS

Cloud computing is driving the IT industry to restructure the application workflow. It offers low-cost services for IT resources over the internet and a pay-as-you-go pricing model. Under cloud computing, IT resources can be utilized on demand. So, you don't need to pay for unused resources or any upfront fees to provision any hardware in advance.

Amazon Web Services (AWS) is a leading cloud services provider. AWS offers different services in various graphical regions, which can be chosen by customers based on their requirements. With AWS, we can create high availability and fault tolerant applications with minimal configurations. AWS reduces the stress of managing on-premises physical servers and allows us to focus on application layers.

The following topics will be covered in this chapter:

Introduction to AWS

Sign-up process

Regions

Installation of the AWS CLI

Introduction to AWS

AWS is a cloud computing platform offered by Amazon. It offers a large set of services that can be utilized in various forms. AWS caters for different services, including infrastructure, networking, storage, databases, security, and many more. These different services can be used in the application life cycle. Also, AWS offers a pay-as-you-go pricing model, which means that the user will only pay for services being used, so the user doesn't have to pay any upfront fees to acquire hardware resources.

AWS offers a web service interface for all services. We can also integrate AWS services via web services with various software to make our application management easier. AWS offers multiple regions to create AWS services.

The user has the choice to select the regions based on the application usage so that latency is low. Each region has multiple Availability Zones (AZ), which means you have an option to select Availability Zones where the application will reside, to avoid failure when one availability zone is down but another may be up.

Services offered by AWS

AWS offers a wide range of services under different categories. The following are some of the services that are offered by AWS.

Compute

Compute offers a computing platform where we can create virtual servers, and deploy and run our applications:

Elastic Compute Cloud

 (

EC2

)

: AWS EC2 is a web service interface that allows users to create and configure

compute machines

in the cloud. It offers scalable compute machines with minimal configuration and reduces overall time to boot new servers. 

EC2 Container Service

S3

): AWS S3 is an object-based storage service over the web. We can store any amount of data and it can be retrieved from anywhere over HTTP. We can also host a static HTML website on S3.

Elastic File System

(

EFS

): AWS EFS is a scalable file storage system that can be used with EC2 instances. EFS can be automatically scaled up and down based on files being added or removed. EFS can also be mounted on an external server residing outside the Amazon ecosystem.

Glacier

: AWS Glacier is a low-cost storage service that can be used for data archiving and infrequently used data. Glacier offers a reliable, secure, and cost-effective storage service.

Storage Gateway

: AWS Storage Gateway is an interface that helps to connect an on-premise storage infrastructure with an AWS storage infrastructure. Storage Gateway offers multiple storage solution types, including file gateway, volume-based, and tape-based types.

Database

AWS offers a variety of database services that can be used for storing application data in RDMSes, NoSQL databases, and caching servers:

Relational Database Service

(

RDS

): AWS RDS is a cloud relational database offered by Amazon that makes it easy to configure and provide scalability. AWS RDS offers a wide range of databases to choose from, including Amazon Aurora, MySQL, PostgreSQL, MariaDB, Microsoft SQL Server, and Oracle. Amazon also provides a database migration service that can be used by consumers to migrate on-premise or external databases to the Amazon Cloud.

DynamoDB

: AWS DynamoDB is a fully managed NoSQL service that provides high performance and scalability. It handles databases in a distributed manner so that consumers do not have to deal with the administration of the database. Consumers will be directly dealing with tables with unlimited storage and they can store and retrieve data.

ElastiCache

: AWS ElastiCache provides a data caching service that can be an in-memory data store that improves application performance. ElastiCache offers two open source in-memory data stores, Redis and Memcached. The user can configure clusters of caching servers that can automatically handle failover.

Redshift

: AWS Redshift is a fully managed data warehouse service provided by Amazon. Redshift allow us to connect via SQL-based clients and business intelligence tools and is focused on analytics. It also offers fast query execution over a large set of datasets.

Networking and content delivery

AWS offers solutions for running companies' infrastructures under a secured cloud. It can deliver content using the Content Delivery Network (CDN) for low latency, and can expose DNS and REST APIs for applications running on the cloud:

Virtual Private Cloud

(

VPC

): AWS VPC allows us to create private and public networks where we can create different Amazon services. Those services will run under our virtual network in the same way as those running on on-premise data centers. We have authority to configure the IP address range, subnets, network gateways, and security layers.

CloudFront

: AWS CloudFront is a global CDN that helps to cache data over edge locations and provide data to the requester faster. The CDN helps to minimize cost and deliver content with low latency.

Direct Connect

: AWS Direct Connect is a dedicated network service where a consumer can connect an on-premise data center directly to the Amazon network. This helps to reduce the time lag for data transmission and we can configure the connections to increase capacity.

Route 53

: AWS Route 53 is a

Domain Name System

(

DNS

) where we can route our request to AWS infrastructures, such as EC2, RDS, or other services. It also has the capability to route to non-AWS infrastructures. It provides scalability and high availability for the Domain Name System service, so users can rely on it. Route 53 is IPv6 compliant.

API Gateway

: AWS API Gateway is a service that exposes the front entry point (URL) for an application. API Gateway helps to build, monitor, and secure APIs, and can scale at any level. We can redirect the API calls to either AWS Lambda, web applications running on EC2, or any other servers.

Migration

AWS offers migration services that reduce the complexity and time for companies to migrate to the cloud:

AWS Migration Hub

:

AWS Migration Hub allows us to monitor the progress of an application's migration within AWS resources and other partnering software tools. This makes it easier for us to get a high level of understanding about the migration's progress.

Application Discovery Service

: AWS Application Discovery Service is an intelligent service that collects and summarizes the usage of applications and their dependent services running on on-premise servers. This service can be where a user wants to migrate a system and wants to collect information about the on-premise server and find out about the dependent applications. It stores the collected data in the Application Discovery Service database, which will be in an encrypted format. Users can then export the data in CSV or XML format.

Database Migration Service
