Amazon Web Services (AWS) is a group of remote computing services that simultaneously makes a cloud computing platform, available over the Internet by Amazon.com. The most important and well-known of these services of Amazon are EC2 and Amazon S3.

AWS is a group of hosting products that aims to take the headache out of traditional hosting solutions. Websites such as Reddit a

nd Services like Dropbox all use AWS.

Reasons to choose Amazon AWS Services:

On the Go Pricing

Amazon took a refreshing approach to the price it is hosting when launching AWS. Every service is like you pay for what you use. It creates a lot of sense for server infrastructure, as traffic tends to be very bursty, especially the more valuable the site is.

Traditional hardware, for the most part, goes unused for 90% of its lifecycle. AWS manages this problem by keeping its moderate pricing.

The Free Tier

The Major reason many people do not use AWS is the absence of knowledge. EC2 is not like a standard hosted solution, as it's created to bring servers online and offline very fast as required. Due to this, many IT professionals were cautious about using EC2 or other AWS services because of the cost associated.

The free tier provides plenty of credit to run an EC2 micro instance 24/7. It runs with S3 storage, EC2 compute hours, Elastic Load Balancer time, and much more. It allows developers to try out AWS's API in their software, which not only improves their software but also binds them to AWS, which help Amazon in the long run.

Performance

There's no disagreement with the speed of AWS. The Elastic Block Storage is nearly as quick as S3 but allows distinct features. EC2 Compute Units provides Xeon-class performance on an hourly rate. The dependability is better than most private data centers in the world, and if there is a problem, you're mostly online, but with minimized capacity.

It is tested using a beautiful application, Chaos Monkey, whereby utilizing this application, it randomly powers down a component in your cloud environment. Then you could figure out whether your application is still running or if it stopped working. Because of this, the chaos monkey brought down our database and a web server. The database, which was an RDS service, immediately switched to another database using the Multi-AZ feature as promised by AWS. In the webserver scenario, when one web server was down, then another webserver was launched utilizing the autoscaling feature, so we finally achieved that AWS delivers High Availability Performance as promised by them. 

In a Classic hosting environment, this probably would have meant downtime and 404 errors as the websites would have just gone dark. But in a genuinely cloud-hosted environment like AWS, there's plenty of difference between processing and storage that sites can be online and continue generating revenue even with reduced functionality.

But the performance ability of AWS is in the storage. The assigned nature of EBS and S3 allows millions of input/output operations every second to all instances. Assume of it like having a raid array of SSDs attached to a specific computer. Add in marvelous bandwidth, and you have a storage system that is capable of vast scaling.

Deployment Speed

If you've ever had to use a hosted web service, you know the pain of speed very well. Classical providers take anywhere from 48-96 hours to arrange a server. Then you have to give a few hours for everything tested.

AWS minimizes that formation from time to minutes. If you use their Amazon Machine Images, you can have a machine deployed and available to establish connections in that short amount of time. It is essential when, for example, you are running a promotion that generates tons of traffic at specific intervals, or need the flexibility to control the requirement product launches.

The Cloud formation Templates is a gift from the AWS which can be used to roll out several environments at the one-click and as well can be rolled down at the single click when it is required. 

Security

Access to the AWS resources can be limited using the IAM(Identity and Access Management). By using the roles in IAM, we can decide the rights for user actions, which automatically reduces any misconduct.

AWS also supports VPC, which can be used to host our services on a private network that is not available from the internet but can communicate with the resources in the same system. It restricts authorization to the resources such that any harmful user over the internet.

These services hosted in the private network can be used using the Amazon VPN or some open-source service like OpenVPN.

Flexibility

An essential feature in AWS is its flexibility. All the services work and exchange information together with your application to automatically find the required demand and handle it as needed.

Combined with the versatile API and the Amazon Machine Images you create, you can have a customized solution that provisions a server instance in under 10 minutes and is ready to establish connections when it comes online. Then you can shut down instances when they are no longer required, making server management a thing of the past.
