Amazon Web Services


Commonly known as cloud computing nowadays, web services in the form of IT infrastructure services began to be offered by Amazon in 2004 for public use.

AWS cloud computing provides a low-cost, scalable, and highly reliable infrastructure platform in the cloud. This has been adopted by thousands of businesses globally. At present, its regions include locations like Asia Pacific, European Union, North America, South America, Canada, China, etc. The locations are widespread to make sure the system is robust and secured against the impact of outages or other glitches.

According to the AWS website, the bouquet of featured services includes the following:

  • Amazon EC2 – Elastic virtual servers in the cloud
  • Amazon Simple Storage Service (S3) – Scalable storage in the cloud
  • Amazon Aurora – High-performance managed relational database
  • Amazon DynamoDB – Managed NoSQL database
  • Amazon RDS – Managed relational database service for MySQL, PostgreSQL,
  • Oracle, SQL Server, and MariaDB
  • AWS Lambda – Run code without thinking about servers
  • Amazon VPC – Isolated cloud resources
  • Amazon Lightsail – Launch and manage virtual private servers
  • Amazon SageMaker – Build, train, and deploy machine learning models at scale.

Why Do Businesses Need Amazon Cloud?

Now that you know what AWS is, here is why your business could do well with it.


Amazon web services make for a durable and secure technology platform. To ensure the safety and integrity of your data, Amazon’s data centers and services have several layers of physical and operational security. AWS also conducts regular audits to ensure its infrastructural security.

It has implemented best practices in security and also provides documentation on how to deploy the security features. It ensures the availability, integrity, and confidentiality of your data and provides ‘end to end’ privacy and security.


There are no long-term commitments or upfront expenses as far as AWS pricing is concerned. It provides low and ‘pay as you go’ pricing. Amazon passes the benefits of cost savings on to customers in the form of lower prices as it manages and builds global infrastructure at scale.

You consume only as much storage or computing power as required. No upfront investment or minimum expenditure is required. Generally, it is not easy to predict the requirements for the resources. So, you might allocate fewer resources than required and impact customer satisfaction or you might allocate excessive resources and not be able to maximize return on investment (ROI).

The flexibility of the cloud can help to achieve the correct balance. You can terminate your relationship with AWS whenever you want to, scale down or scale up as required, and have a fully self-service experience online.

You can get new resources nearly at once. Also, you can reduce costs and drive revenues by taking on new opportunities as the cloud enables you to respond rapidly to changes small or large. You are not even limited to a set amount of computing resources, bandwidth, or storage.

Flexibility and Openness

Amazon web services is a platform agnostic to operating systems and languages. You select the programming model or development platform that can be the most beneficial for your business. You can select the services (one or more) you want to use and also select how to use them. The flexibility lets you concentrate on innovation rather than infrastructure.

You can use the programming languages, architectures, operating systems and databases you are familiar with. In this manner, there won’t be any need for your IT personnel to pick up new skills and the overall time to market and productivity will improve.

It is cost-effective and easy to migrate legacy apps to the cloud. You don’t have to rewrite apps and can utilize advanced capabilities of computing to move legacy apps to AWS cloud.

You can migrate discrete components of legacy apps to move SOA-based solutions to the cloud. Generally, these components are self-contained apps with not many internal dependencies.

AWS makes it easy to be productive, once you get started, whether you want to host a production solution or prototype an app. A number of customers improve their time to market on account of the flexibility that AWS offers.


Elasticity and Scalability

AWS lets you iterate, experiment, and innovate quickly through its huge global cloud infrastructure. You can quickly scale up or scale down on the basis of demand. You can also use new apps, rather than wait for months for hardware.

So, you can swiftly subtract or add resources in accordance with customer demand and manage costs more effectively. You can also avoid resource provisioning upfront for projects with short lifetimes and variable consumption rates.

You have to pay only for as much as you use, regardless of whether you deploy thousands of virtual servers or only one and whether you need them 24/7 or for only a few hours daily.

In the context of AWS, the ability to scale computing resources downwards or upwards without difficulty and with very little friction is known as elasticity. You can use AWS to allot resources through API calls, in place of buying hardware, setting it up, and maintaining it to allot resources to apps.

Auto-scaling and elastic load balancing can scale up Amazon cloud-based resources automatically in case of the unforeseen increase in demand and also scale them down if demand gets reduced. The AWS cloud also proves useful for jobs recurring at regular intervals, jobs that are ‘mission critical’ and jobs in the short term.

And now that we’ve seen how Amazon cloud is extending advantages to businesses, we also find it important to discuss a service within AWS – Amazon Elastic Cloud 2.

What is AWS EC2 and Why Businesses are Opting for it?

“Amazon Elastic Compute Cloud (Amazon EC2) provides scalable computing capacity in the Amazon Web Services (AWS) cloud. Using Amazon EC2 eliminates your need to invest in hardware up front, so you can develop and deploy applications faster.”

It lets you use Amazon’s environment for computing and control your computing resources completely. As your computing needs change, you can rapidly scale capacity as you can get and boot new server instances in a few minutes through Amazon EC2.

It also protects against common scenarios for failure and provides developers with tools to develop applications that are failure resilient.

So, is that all why businesses are going for it? Well, there is more to it. And to find that out, let’s learn the important features of Amazon EC2.
