Accessing the AWS Cloud Computing Platform.

AWS provides many cloud services that you can combine to meet business or organizational needs. To access AWS Cloud services, you can use the following tools.
1. AWS Management Console,
2. AWS Command Line Interface(CLI),
3. AWS Software Development Kits(SDKs).

1. AWS Management Console is a web application for managing AWS Cloud services. The consol provides an user interface for performing many tasks. Each service has its own consol, which can be accessed from AWS Management Console. The consol also provides information about the account and billing.

2. AWS Command Line Interface(CLI) is a verified tool used to manage AWS Cloud Services. With just one tool to download and configure, you can control multiple services from the command line and automate them through scripts.

3. AWS Software Development Kits(SDKs) provide an application programming interface (API) that interacts with the web services that fundamentally make up the AWS platform. The SDKs provide support for many different programming languages and platforms to allow you to work with your preferred language. While you can certainly make HTTP calls directly to the web service endpoints, using the SDKs can take the complexity out of coding by providing programmatic access for many of the services. 

Why AWS No. 1 in Cloud Computing?

At its core, AWS provides on-demand delivery of IT resources via the Internet on a secure cloud services platform, offering compute power, storage, databases, content delivery, and other functionality to help business scale and grow. Using AWS resources instead of you own is like purchasing electricity from a power company instead of running your own generator, and it provides the key advantages of cloud computing: Capacity exactly matches your need, you pay only for what you use, economies of scale result in lower cost, and the service is provided by vendor experienced in running large-scale networks.

AWS global infrastructure and AWS approach to security and compliance are key foundational concepts to understand as you prepare for the exam.

Advantages of Cloud Computing.

1. Variable vs. Capital Expenses-

Instead of having to invest heavily in data centers and servers before knowing how you are going to use them, you can pay only when you consume computing resources and pay only for how much you consume.

2. Economies of Scale-

Another advantage of cloud computing is that organizations benefit from massive economies of scale. By using cloud computing, you can achieve a lower variable cost than you would get on your own. Because usage from hundreds of thousands of customers is aggregated in the cloud, provides such as AWS can achieve higher economy of scale, which translates into lower prices. 

3. Stop Guessing Capacity

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, organizations can stop guessing about capacity requirements for the infrastructure necessary to meet their business needs. They can access as much or as little as they need and scale up or down as required with only a few minutes’ notice.

4. Increase Speed and Agility-

In a cloud computing environment, new IT resources are one click away, which allows organizations to reduce the time it takes to make those resources available to developers from weeks to just minutes. This results in a dramatic increase in speed and agility for the organization, because the cost and time it takes to experiment and develop is significantly lower.

5. Focus on Business Differentiation 

Cloud Computing allows organization to focus on their business priorities, instead of on the heavy lifting of racking, stacking, and powering servers. By embracing this paradigm shift, organizations can stop spending money on running and maintaining data centers. This allows organizations to focus on projects that differentiate their business, such as analyzing petabytes of data, delivering video content, building great mobile applications, or even exploring Mars.

6. Go Global in Minutes

Another advantage of cloud computing is go global in a minutes. Organizations can easily deploy their application to multiple locations around the world with just a few clicks. This allows organizations to provide redundancy across the globe and to deliver lower latency and better experiences to their customers at minimal cost. Going global used to be something only the largest enterprises cloud afford to do, but cloud computing democratizes this ability, making it possible for any organization. 

What is Cloud Computing?

Cloud computing is the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing. With cloud computing, you don't need to make large up-front investments in hardware and spend a lot of time managing that hardware. Instead, you can provision exactly the right type and size of computing resources you need to power your nearest bright idea or operate your IT department. With cloud computing, you can access as many resources as you need, almost instantly, and only pay for what you use.

In a simple ways, cloud computing provides an easy way to access servers, storage, databases, and a broad set of application services over the Internet. Cloud computing providers such as AWS own and maintain the network-connected hardware required for these application services, while you provision and use what you need for your workloads.

What is AWS?

In 2016, Amazon Web Services, Inc.(AWS) began offering IT infrastructure services to business in the form of web services, now commonly known as cloud computing. One of the key benefits of cloud computing is the opportunity to replace up-front capital infrastructure expenses with low variable costs that scale with your business. With the cloud, business no longer need to plan for and procure servers and other IT infrastructure weeks or months in advance. Instead, they can instantly spin up hundreds or thousands of servers in minutes and deliver results faster.

AWS provides a highly reliable, scalable, and low-cost infrastructure platform in the cloud that powers hundreds of thousands of business in more than 190 countries.
