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. Fo 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. its 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, it'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 usage from hundreds of thousands of customers is 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 AmazonWeb Service. Before a factory would classically build an electricity plant and usage 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 youwill 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 newAWS 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 day1. 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 Tierusage 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 Budgets has 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 Free Tier-eligible service usage is free.
