Amazon Web Services (AWS) – By Sagar Jaybhay
History & Basics
Amazon Web Services (AWS) is Amazon’s cloud internet hosting platform that gives versatile, reliable, scalable, easy-to-use, and efficient solutions. This tutorial covers varied vital topics illustrating however AWS works and the way it’s helpful to run your website on Amazon Web Services.
In 2006, Amazon Web Services (AWS) began to supply IT services to the market within the kind of internet services, that is these days called cloud computing. With this cloud, we want not arrange for servers and different IT infrastructure that takes up a lot of your time before. Instead, these services will instantly spin up a whole lot of thousands of servers in minutes and deliver results quicker. we tend to pay just for what we tend to use with no up-front expenses and no long commitments, that makes AWS price economical.
Today, AWS provides an extremely reliable, scalable, affordable infrastructure platform within the cloud that powers multitude of companies in one hundred ninety countries around the world.
Cloud computing is AN internet-based computing service during which massive teams of remote servers are networked to permit centralized information storage, and on-line access to pc services or resources.
Using cloud computing, organizations will use shared computing and storage resources instead of building, operating, and up infrastructure on their own.Cloud computing could be a model that permits the subsequent features.
Users will provision and unharness resources on-demand. Resources will be scaled up or down mechanically, counting on the load. Resources are accessible over a network with correct security. Cloud service suppliers will alter a pay-as-you-go model, wherever customers are charged supported the kind of resources and per usage.

A private cloud conjointly provides nearly similar options as public cloud, however the information and services area unit managed by the organization or by the third party just for the customer’s organization. during this kind of cloud, major management is over the infrastructure therefore security connected problems area unit reduced.
A hybrid cloud is that the combination of each non-public and public cloud. the choice to run on non-public or public cloud sometimes depends on numerous parameters like sensitivity of information and applications, business certifications and needed standards, laws, etc.
Advantages of Cloud Computing
Here could be a list of a number of the foremost vital benefits that Cloud Computing must provide −
Cost-Efficient − Building our own servers and tools is long likewise as costly as we want to order, pay for, install, and put together overpriced hardware, long before we want it. However, exploitation cloud computing, we tend to solely buy the number we have a tendency to use and after we use the computing resources. during this manner, cloud computing is value economical.
Reliability − A cloud computing platform provides far more managed, reliable and consistent service than an in-house IT infrastructure. It guarantees 24×7 and three hundred and sixty five days of service. If any of the server fails, then hosted applications and services will simply be transited to any of the accessible servers.
Unlimited Storage − Cloud computing provides virtually unlimited storage capability, i.e., we want not worry concerning running out of cupboard space or increasing our current space for storing accessibility. we are able to access the maximum amount or as very little as we want.
Backup & Recovery − Storing information within the cloud, backing it up and restoring identical is comparatively easier than storing it on a physical device.

Disadvantages of Cloud Computing
Although Cloud Computing provides an exquisite set of benefits, it’s some drawbacks yet that always raise questions.
Security problems : Security is that the major issue in cloud computing. however, storing knowledge and necessary files on external service providers forever bears a risk. AWS cloud infrastructure is intended to be the foremost versatile and secured cloud network. It provides scalable and extremely reliable platform that allows customers to deploy applications and knowledge quickly and firmly.
Technical problems : As cloud service providers provide services to range of purchasers on a daily basis, to boot, if the web association is offline then we are going to not be able to access any of the applications, server, or knowledge from the cloud. Not easy to modify service providers. Cloud service suppliers guarantees vendors that the cloud are versatile to use and integrate, but change cloud services isn’t simple.
