Why companies are adopting AWS for their applications?

Cloud migration is now a trend in IT and AWS is becoming the first choice of Companies. Organizations started trusting AWS for cloud services from all kind including IT, healthcare, finance as well as medical.

Let us understand why AWS is becoming the first choice of various companies.

Why companies are adopting AWS for their applications?


AWS follows the “a la carte” approach, which means you pay what you use. This makes a lot of sense otherwise if we go with third-party hosting, we also need to pay for those things which we do not even use. AWS is providing almost 1430+ services in the cloud market on very cost effective mode.

The Free Tier

AWS does not provide hosting like traditional hosting companies. EC2 service(the backbone of AWS) provides the free credit to run your small web application with micro instance 24/7. Because of this, IT professionals are leery of using EC2 (or the rest of the AWS suite). EC2 is designed to bring web applications online & offline very quickly as per our need.


There’s no denying about the speed of AWS. The Performance of Elastic Block Storage (which use with Amazon EC2 instances in the AWS Cloud) is nearly as fast as S3 but provides different features. EC2 Compute Units give the Xeon-class performance on an hourly rate. The reliability of EC2 is better than most private data centers in the world, and if there is a problem with your instance, you can be up in a few minutes.

EC2 comes with some features like Load balancing, Autoscaling etc. Load balance service helps to manage load on your application. Let say you are running your web application on 2 instances and attach those instances to your Load balancer after that Load balancer will take care of your load. It will throw traffic on one instance to other instance based on load.

Like Load balancer but not in terms of functionality, Autoscaling takes care of your web application with the number of instances what we provide at the time of creation. Service will add or remove server instances as per the load automatically. We do not need to do anything. If the database server is down, you can immediately switch to another database using the Multi-AZ feature as promised by AWS.

But the main performance of AWS is in the storage. The distributed nature of EBS and S3 generates millions of input/output operations. Just think of it like you are having a raid array of SSDs attached to a particular computer, add incredible bandwidth, and you have a storage system ready which is capable of large scaling with 99.999999999% reliability.


If you’ve ever provisioned or deployed to a hosted web service, you know this pain very well. Traditional providers take nearly 48-96 hours to provision or deploy a server. Through AWS, you have to spend a few hours tweaking it and getting everything ready.

AWS helps to shrink the deployment time to minutes by utilizing their Amazon Machine Images. If you use AMIs, you can have a machine deployed and ready to accept connections in a short amount of time. This will be important when you need to run a promotion application that generates tons of traffic at specific intervals.

There are some services listed which help to deploy the resources or applications apart from launching the instances/virtual machines;

  1. CloudFormation
  2. Elastic Beanstalk
  3. AWS CodeDeploy
  4. AWS CodeCommit

The Cloudformation service is a gift from the AWS which can be used to roll out resources in multiple environments by simply clicking on the button as well as resources can be rolled down by simply clicking on the button when the requirement recedes.


We can restrict the usage of AWS resources by using the IAM(Identity and Access Management) service of AWS. By defining the policies and roles, we can define the privileges for user actions which reduce malpractices.

AWS provides VPC, which can be used to host our services like database server on a private network/subnet which will not be publicly accessible from the internet, but we can access/communicate with the other resources in the same network.


Combined with the fantastic APIs and the Amazon Machine Images, you can have a completely customized solution that provisions a server instance in few minutes and is ready to accept connections. Once it comes online, you can quickly shut down instances when they are no longer needed.

But the way, Companies are moving to AWS, it is generating jobs which requires AWS hot skills and hiring those candidates who have AWS skills and hands-on experience on AWS services.
