Since every company has started to adopt the cloud services in one way or the other, and AWS is a major player in the cloud services industry, it makes sense to learn about AWS Cloud services.
There are various cloud services out there. The top three cloud providers are below:
- Amazon Web Services (AWS)
- Microsoft Azure
- Google Cloud Platform (GCP)
Let us begin the AWS tutorial by learning about the basics of AWS.
What is AWS?
Amazon Web Services(AWS) is a Amazon.com subsidiary which offers cloud-computing services at very affordable rates, therefore making its customer base strong from small scale companies like Pinterest (which has just 5 employees) to big enterprises like D-Link.
What is Cloud Computing?
It is the use of remote servers on the internet to store, manage and process data rather than a local server or personal computer.
There are basically 3 categories in cloud computing:
- SaaS (Software as a Service)
- It allows companies to use software without having to purchase them, which reduces the expenditure of the company drastically, since they are already installed on the cloud server they can be quickly deployed and therefore saves time.
- PaaS (Platform as a Service)
- It allows developers to build applications, collaborate on projects without having to purchase or maintain infrastructure.
- IaaS (Infrastructure as a Service)
- It allows companies to rent servers, storage space, etc. from a cloud provider.

AWS Pricing
- AWS follows a pay per use model, meaning you only pay for what you use. For example, if you are using 10GB of space on S3 on AWS, you would be paying only for that 10GB, traditionally you have to buy an ‘x’ amount of storage say 20GB in advance, and even if you are using 10GB in the purchased space, you will be billed for the whole 20GB.
- You can get started with AWS for free, AWS runs a free usage tier in which you can use the AWS services in a very basic manner for free.
Pay-As-You-Go:
In contrast to typical IT cost models that involve up-front capital investments for hardware and software, pay as you go is a cost model for cloud services that includes both subscription-based and consumption-based models. Pay-As-You-Go (PAYG) is another name for Pay & Go, Pay Per Usage, Pay Per Use or Pay-As-You-Use.
- Cloud computing services are divided into three types, each of which might employ a different pay-as-you-go approach.
Infrastructure as a Service (IaaS) is a term that refers to Customer’ pay by the hour, week, or month for the services they consume. Some cloud providers charge based on how much virtual machine (VM) space is used. This strategy eliminates the need for consumers to deploy their own gear and software. IBM, Hewlett-Packard, Microsoft, and Amazon Web Services are among the IaaS providers. - PaaS (platform as a service): It can be priced by the application/user or by the GB of RAM utilized each hour. When you terminate a VM, Microsoft’s PaaS now uses a per-minute pricing mechanism that keeps the VM’s state and settings while stopping the meter. PaaS vendors include Google, Oracle Public Cloud, and Windows Azure.
- Software as a Service (SaaS) is a term that describes how software Features, storage capacity, or a per-user basis can all be used to determine to price. Salesforce.com, NetSuite, and Microsoft Dynamics are just a few of the vendors on the list.
Next, in this AWS tutorial, let’s learn how AWS can be used.
How can AWS be used?
- A large enterprise can utilize AWS to deliver training material to its distributed workforce worldwide.
- Construction consulting companies can use AWS for rendering construction prototypes.
- A manufacturing company can expand and scale up by taking advantage of the high scalability of clouds.
- Media companies use AWS to distribute their video or audio content worldwide.
- Companies can analyze their data using AWS ML algorithms to extract valuable insights. Formula 1 currently uses AWS to gather real-time information about races for analysis and run deep performance tests.
Advantages of AWS
- Economical
AWS lets clients pay only for the services they use, making it considerably more cost-effective. Furthermore, if we want to build a real server, we will have to pay for the installation and configuration of pricey hardware. As a result, it is preferable to use cloud services from cloud service providers, particularly AWS, which are both cost-effective and reliable.
- Reliability
AWS is extremely dependable since it operates 24/7 all year. If one of the servers fails, the hosted apps and services will continue to function since they can simply be shifted to another server.
- Limitless Storage Capacity
There is no limit to the amount of data that may be store. Users are often concerned about storage capacity, but AWS provides nearly limitless storage, so users do not have to pay any additional fees for storage. They can store as much as they wish.
- Recovery and backup
When compared to storing data on a physical device, AWS makes it easier to store, backup, and recover data. Almost all cloud service providers now provide the ability to restore all data in the event of a data loss, making it acceptable and helpful for any company.
- Easier Information Access
Access to Information Is Made Easier. After enrolling on the AWS cloud service offering platform, users may access their information from anywhere in the globe as long as they have a strong Internet connection. These features, however, differ depending on the type of account or plan selected. We will now continue learning about creating an AWS account.
