COLUD COMPUTING :

Cloud computing means that instead of all the computer hardware and software you're using sitting on your desktop, or wherever inside your company's networks. For you as a service by another company and opened over the internet, usually in the entire whole way. Exactly where the hardware and software are located and how it all works doesn’t matter to you, the user. it's just somewhere up in the unclear “cloud” that the internet represents.

              Cloud computing is a catchword that means different things to different people.  For some, s just another way of describing IT(information technology)“contract out”, others use it to mean any computing services provided over the internet or a related network, and some define it as any bought-in computer services you use that sits outside your firewall. However, we define cloud computing, there’s no doubt it makes the most sense when we stop talking about abstract definitions and look at some simple, real example-so let’s do just that.

SIX  Advantages  of  Cloud Computing:

• Trade capital expense for variable expense – Instead of having to participate heavily in data centers and servers before you know how you’re going to use them, you can pay only when you consume computing resources, and pay only for how much you consume.
• Benefit from massive economies of scale – By using cloud computing, you can achieve a lower variable cost than you can get on your own. Because of usage from hundreds of thousands of customers are aggregated in the cloud, providers such as AWS can achieve higher economies of scale, which translates into lower pay-as-you-go prices.
• Stop guessing capacity – Eliminate guessing on your infrastructure capacity needs. When you make a capacity decision prior to deploying an application, you often end up either sitting on expensive idle resources or dealing with limited capacity. With cloud computing, these problems go away. You can access as much or as little capability as you need, and scale up and down as required with only a few minutes’ notices.
• Increase speed and agility – In a cloud computing environment, new IT resources are only a click away, which means that you reduce the time to make those resources available to your developers from weeks to just minutes. This results in a dramatic increase in agility for the organization since the cost and time it takes to experiment and develop is significantly lower.
• Stop spending money running and maintaining data centers – Focus on projects that separate your business, not the infrastructure. Cloud computing lets you focus on your own customers, rather than on the heavy lifting of racking, stacking, and powering servers.
• Go global in minutes – Easily deploy your application in multiple regions around the world with just a few clicks. This means you can provide lower latency and a better experience for your customers at a minimal cost.

INTRODUCTION TO AWS :

AWS full form Amazon Web Service. Before a factory would classically build an electricity plant and usage it for their drives. Then power specialists would manage electricity plants to provide reliable power supply at a very low cost to these factories as a whole. The electricity could be created through bigger productivity and the price in this model is also low. AWS cloud follows a similar model where instead of building large scale structures, companies can opt for cloud services where they can get all structures they could ever need.

AWS is a growing cloud computing platform that has a significant share of cloud computing with respect to its competitors. AWS is geographically spread into regions to guarantee system robustness and outages. In Japan, Eastern USA, two locations in Western USA, Brazil, Ireland, Singapore, and Australia regions there are central hubs in place. There are over 50 services like application services, networking, storage, mobile, management, compute and many others that are available for the client easily.

AWS free tier and AWS Budgets :

In this tutorial you will learn how to control your costs while discovering AWS service presents using the AWS Free Tier then using AWS Budgets to set up a cost budget to monitor any costs related to your usage.

Whether you're looking for compute power, database storage, content delivery, or other functionality, AWS has the services to help you build sophisticated applications with increased flexibility, scalability, and reliability. But how do you get started experimenting and building with AWS services while keeping your costs low or free?

The AWS Free Tier is a deduction program that lets you gain free, hands-on practice with AWS products and services. All-new AWS accounts include the Free Tier so you don't have to sign up for it, allowing you to try out the services you need to build your workloads from day 1. With over 80 services in the Free Tier, you can do lots of exploring at a reasonable cost, or even for free.

Monitoring your service usage and allied costs while you are discovering and scaling your usage of AWS is often cited as a top concern. To make sure you don't exceed the Free Tier usage thresholds and your overall budget, we indorse using AWS Budgets. AWS Budgets is a cost control tool that allows you to create custom cost budgets that alert you when you exceed your budgeted threshold.

In the next few minutes, you will learn about the AWS Free Tier offer, discover how AWS Budgets monitors your Free Tier usage by default, and create a total monthly cost budget that alerts you when you exceed (or are forecasted to exceed) using AWS Budgets.

It is a best practice to create a total monthly cost budget for each AWS account you use. AWS Budgetshas a Free Tier limit of 62 budget days per month, so creating a single budget falls within the AWS Free Tier limit. As the name implies, AWS FreeTier-eligible service usage is free.

Set Up an AWS Account and Create a user:

Before you use Amazon Polly for the first time, complete the following tasks:

->Sign up for AWS

->Create an IAM User

Sign Up for AWS :

When you sign up for Amazon Web Services (AWS), your AWS account is automatically signed up for all services in AWS, including Amazon Polly. You are charged only for the services that you use.

With Amazon Polly, you pay only for the resources you use. If you are a new AWS customer, you can get started with Amazon Polly for free.

To Create AWS  Account :

1. Open https://portal.aws.amazon.com/billing/signup

2. Follow the online instructions.

Part of the sign-up procedure involves receiving a phone call and entering a verification code on the phone keypad.

Note your AWS account ID because you'll need it for the next step.

Create an IAM User :

Services in AWS, such as Amazon Polly, require that you provide permits when you contact them so that the service can regulate whether you have approvals to access the incomes maintained by that service. The console requires your password. You can create access keys for your AWS account to access the AWS CLI or API. However, we don't endorse that you access AWS using the permits for your AWS account. Instead, we praise that you use AWS Identity and Access Management (IAM). Create an IAM user, add the user to an IAM group with administrative permissions, and then grant directorial permissions to the IAM user that you created. You can then access AWS using a special URL and that IAM user's credentials.

If you signed up for AWS, but you haven't created an IAM user for yourself, you can create one using the IAM console.
