What is AWS?
Amazon Web Services (AWS) is the market leader in IaaS (Infrastructure-as-a-Service) and PaaS (Platform-as-a-Service) for cloud ecosystems, which can be combined to create a scalable cloud application without worrying about delays related to infrastructure provisioning (compute, storage, and network) and management.

Amazon Route 53 – AWS DNS service
Amazon Aurora – High-performance managed relational database
Amazon Cloud Watch – Monitor AWS environment
Amazon DynamoDB – Managed NoSQL database
Amazon RDS – Managed relational database service for MySQL, PostgreSQL, Oracle, SQL Server, and MariaDB
Amazon Lightsail – Launch and manage virtual private servers

Let’s dive into a little bit more detail on some of these.
Amazon VPC – Amazon Virtual Private Cloud (VPC) provisions an isolated section of the AWS Cloud to launch AWS resources within a self-defined virtual network. This gives enterprises complete control over their virtual networking environment. Companies can use Amazon VPC with combined with their own internal network and harness the true power of cloud.
Amazon EC2: Server configuration and hosting – Amazon Elastic Compute Cloud (EC2) delivers secure, reliable compute capacity and simplifies elastic web-scale computing for developers, allowing them to build failure-resistant applications. Amazon EC2 changes the economics of computing by allowing the pay as go model for capacity that you actually use. This allows the companies to quickly scale capacity, both up and down, as the computing requirements change. What’s more customers have complete control and the ability to interact with all instances.
Amazon S3: Data storage and movement – S3 offers scalability, data availability, security and performance. It gives customers of all sizes and industries the ability to store and protect any amount of data for a range of use cases such as websites, mobile applications, backup and restore, archive, enterprise applications, IoT devices and big data analytics. According to AWS, Amazon S3 is designed for 99.999999999% (11 nines) of durability, and stores data for millions of applications for companies all around the world.
AWS Lambda: Serverless Compute – AWS Lambda gives companies serverless compute capabilities that allow them to run code for virtually any type of application or backend service without provisioning and running servers. This service is fully managed by AWS, so no administration is needed – upload code and let Lambda handle everything needed to run and scale your code with high availability. Companies only pay for the compute time consumed.
Amazon Route 53: The AWS DNS service – Route 53 is the network of DNS Servers hosted in various AWS regions all around the world. It handles DNS routing with the high-speed and low cost. Translate machine hosts and named application to IP addresses and back within your VPC and connect resources like web servers, S3 buckets, and elastic load balancers. Using API, developers can easily automate the configuration changes to Route 53.
Amazon Cloud Watch: Environment Monitoring – Be it DevOps engineers, site reliability engineers (SREs), developers or IT managers, everyone can get actionable data and insights about applications through Amazon Cloud Watch. This service allows user to react to system-wide performance changes, optimize resource utilization and get a unified view of the operational health of AWS resources, applications and services that run on AWS and on-premise servers. Data is presented in forms, metrics, logs and events. User can even take actions based on the health of resources, example scale-up or scale-down.
