Amazon web services(AWS) is a congregation of remote computing services or web services that together make up a cloud computing platform offered web form Amazon.com. Prominent of those are Amazon EC2 and Amazon EC3.
AWS is a suite of hosting products that aims to take the problem out of the traditional hosting solutions. AWS isn’t just for the Dropboxes and Reddits of the world though users can host a couple of servers on AWS and quite efficiently too.
When to Use :-
“a la carte” :- We mostly use this term in referring our DTH and selecting required channels and paying for them. So this is the same. Our conventional hardware gets unused mostly 90% of its life cycle. To avoid this AWS took a refreshing approach to pricing its hosting when launching AWS, so its helps by keeping it cheap during the slow times.
There’s no denying the speed of AWS. The elastic block storage is nearly a s fast as S3, but provides different features. The reliability is better than most private data centres in the world, and if there is a problem, you’re still online but with reduced capacity.
In a traditional hosting environments, this would have probably meant downtime and errors would occur. But in a truly cloud-hosted environment like AWS, there’s enough separation between processing and storage that sites can remain online and continue generating revenue even with reduced functionality
AWS shrinks the deployment time to minutes. If you utilise their Amazon machine images, you can have a machine deployed and ready to accept connections in that short amount of time.
This is important when you are running a promotion that generates tons of traffic at intervals or just need flexibility to handle the demand when a new product launches.
The cloud formation templates is a gift from the AWS which can be used to roll out multiple environments t the click of button and as well can ve rolled down at the click of a button when required
The most important feature in AWS is its flexibility. All the services work and communicate together with your application to automatically judge demand and handle it accordingly.
Combined with the fantastic API and the Amazon Machine Images you create, you can have a completely customized solution that provisions a server instance in less than 10 minutes and is ready to accept connections once it comes online.
Then you can quickly shut down instances when they are no longer needed, making server management a thing of the past.
Access to the AWS resources can be restricted using the IAM using the roles in IAM we can define the privileges for user actions which greatly reduces any malpractices.
AWS also provides VPC, which can be used to host our services on a private network which is not accessible from the internet, but can communicate with the resources in the same network. This restricts the access to the resources such that any ill-intentioned user from the internet.
These resources hosted in the private network can be accessed using the Amazon VPN or some open source like OpenVPN.
