What is AWS?
Welcome to the Amazon Web Services guide. In this guide, we will see about AWS and cloud computing. We will discuss various domains in Amazon Web Services detailed. Prerequisites to take the course is having some knowledge on how an application is deployed on servers and small knowledge on managing computing systems.
First, we need to understand what cloud computing is, It’s the basis of understanding AWS.
What is cloud computing?
Cloud computing refers to a service hosted on the internet and you can access the service remotely using the internet. Availability of a service like data storage, servers, or any computing resource over the internet is cloud computing. You don’t manage it personally and it’s more like renting a resource.
Simply to put, Cloud computing is the use of remote computing resource to store, manage and process data rather than a local server or personal computer.
Due to its huge success lot of people trying their hands-on cloud computing. There are a lot of players out there who are providing cloud services as listed,
- Google Cloud platform
- Amazon web service
- Microsoft Azure
- Digital ocean
- IBM Cloud
What is AWS?
It’s a platform where Amazon offers their cloud services like a database, servers, computing machines, file storage, etc. where you can rent them and pay for them according to your usage.
According to various sources, Amazon Web Services (AWS) is a secure cloud services platform, offering computing power, database storage, content delivery, and other functionality to help businesses scale and grow.
How does AWS make working so easy?
In olden days, if you want to deploy an application you have to buy a server, and servers are not cheap pals. You need to invest a lot of money in it and a lot of time to setup up it. You also need to put up an infrastructure to maintain your server. If it went down, then you need to troubleshoot it and your business will be down for that time. Since websites have different peak times for traffic, we need to buy more server to scale up or down. We have to manage everything manually. But with AWS, you don’t need to buy a server, you rent it and deploy and pay only for what you use. No more expensive server. Amazon will manage it for you. If the server goes down, Amazon will spawn up a new instance for your application. With AWS you don’t need to maintain an infrastructure for your servers, all you need is to concentrate on your business goals.

Advantages of AWS
In this section, we will compare three giants in cloud computing. According to a recent report, the following cloud players are ranked as the top three cloud providers.
- Amazon web service
- Microsoft Azure
- Google cloud platform
Why AWS are top of the other two?
The biggest factor for AWS success is because it offers more services compared to Azure and Google cloud. It continues to grow exponentially and support recent technologies. The scope of operation that can be done on AWS is massive. AWS is more mature than the other two. Amazon’s biggest weakness is cost structure, it is very confusing for enterprises. Amazon supports all level enterprises (from small to large).
Google cloud and Microsoft Azure are late to market than AWS, and also, they offer fewer services than AWS. One of the biggest factors for the success of Azure is the Windows operating system is widely used. So, it makes sense to use Azure for Windows-based application servers. Google have really well-managed cost structure. It’s easy to get started with Google cloud than the other two.
Understanding AWS and What you can do with AWS?
AWS is not a single service; it offers a board set of cloud-based products. Let’s see them one by one.
List of services provided by AWS,
- Networking and Content delivery
- Security, Identity, and Compliance
- Developer tools
- Management tools
You can deploy your application in compute. Compute is referring to computing powers. Some popular services in compute are Amazon

- Redshift which is a close relative to PGSQL.
- Elasticache supports in-memory cache services like Memcached and Redis.
- DynamoDB is a highly scalable NoSQL database with very low latency.
Note: Please understand the difference between database and storage. Storage is a service based on the file system where you can store executables. But a database cannot include executable files.
You can get insights into the data you have. You can also create visualizations on the data you analyzed. Some set of services like
- Athena for running SQL queries on S3 bucket.
- Quick Sight for business insights and data visualizations.
