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.
New and existing companies can build their digital infrastructure partially or entirely in the cloud with AWS, making the on-premise data center a thing of the past. The AWS cloud ensures infrastructure reliability, compliance with security standards, and the ability to instantly grow or shrink your infrastructure to meet your needs and maximize your budget, all without upfront investment in equipment.
Amazon includes a powerful, scalable load balancing solution in AWS Elastic Load Balancer (ELB). ELB ensures that client requests are sent to the appropriate servers and avoiding any server hotspots (over-utilizing one server and under utilizing others)
AWS supports two types of load balancing: classic Load balancing and Application Load Balancing.
Classic Load Balancing, which analyzes basic network and application data and ensure fault tolerance if one of the EC2 instances running web application happens to fail.
Application Load Balancing, which looks at content request and routes traffic to the appropriate container or microservice based on the Application content information.
As with most AWS services, you only pay for the services that you use. In case of ELB service, you pay for by an hour and by the amount of data processed.
Amazon Cloudfront is a global content delivery system that leverages Amazon’s vast global infrastructure to deliver contents with optimized speed and cost. CloudFront ensures that content is closer to the users and improves the user experience by delivering the content faster by serving the content from the AWS region closer to the end user.
Cloudfront works seamlessly with AWS services. With no minimum usage commitment, experimenting with configurations and instances to find ways to improve performance is extremely easy.
AWS Elastic Block Storage provides persistent Block-level storage volumes for your EC2 instances with low latency. It also allows your system to access high speed SSD storage and layer your security with Access Control Lists and encryption.
Handle DNS routing with the high-speed, low cost Route 53 service from AWS. 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. Route 53 is the network of DNS Servers hosted in various AWS regions all around the world. Using API, developers can easily automate the configuration changes to Route 53.
