What Is Amazon Web Services(AWS): Its Uses and Services

AWS or the Amazon Web Services is Amazon’s cloud computing platform that offers a mix of packaged software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). In 2006, Amazon launched AWS from its internal infrastructure that was used for handling online retail operations. It was one of the first companies to provide users with computing, throughput, and storage as needed on the basis of pay-as-you-go cloud computing model.

There are several availability zones (AZs) present in regions across the world with data centers. An AZ is a location with multiple physical data centers. A collection of AZs connected by network links with low latency is termed as a region. As an AWS customer, you will be setting up virtual machines and replicating data in different AZs. This helps in building a reliable infrastructure resistant to failure of servers or the data center.

What are AWS uses:
AWS Uses

Currently, AWS is powering much of the infrastructure of the internet. The platform contains everything that you might need for your small, mid-sized or large corporation. Here are a few business advantages of using AWS:

1. Simple Storage Service

Amazon AWS provides S3 or Simple Storage Service that can be used for sharing large files or small files to large audiences online. Depending on the web server type that you are using, you can quickly run out of resources as sharing huge volumes of data online is very expensive. AWS provides cloud storage for your use that offers scalability for file sharing.

2. Simple Email Service

When you want to send emails to thousands of customers, you can’t just use an email service like Outlook or Gmail. Even if somehow you manage to send out the emails, email providers like Yahoo and Gmail will treat them as spam messages. Simple Email Service of Amazon is able to handle such transactional emails at an affordable cost.

3. CloudFront

Web data is transferred from a central server to an edge server’s distributed network which is closer to the location of the end-user. This task is performed by the Content Delivery Network or CDN. This distributes the website traffic loads better, improving the load times and providing a better experience for the end-user. Large CDNs are expensive. Amazon’s CDN service, CloudFront manages to bring everything under a single room and with no limit to its scalability.

4. Website hosting

AWS offers the advantage of not worrying about exceeding the allocated usage of resources. Hosting a website on AWS might not be a one-click installation but its scalability makes it perfect for hosting different websites.

5. File sharing system

Normally, in a large company, one central drive is used by all the computers for storing and sharing files with other members of the team. AWS offers a file-sharing system that is best suited for an organization with employees around the world. Once you set everything up, it works on scale forever. You will never run out of drive space and you will have access to the files from anywhere in the world.

Here are some other advantages of incorporating AWS in your business:

  • It allows the organizations usage of familiar operating systems, architectures, databases, and programming models.
  • There are no long-term commitments or up-front payment. You only pay for what you use which makes it a very cost-effective service.
  • You don’t have to spend a single penny to run and maintain data centers
  • With AWS services, you can enjoy faster deployments.
  • Adding or removing capacity is very easy.
  • You can quickly get access to the cloud with limitless activity.
  • Compared to private servers, the cost of ownership is low.
  • AWS services have hybrid capabilities.
  • It offers centralized management and billing.
  • Deployment of applications in several regions across the world is possible with just a few clicks.

What are AWS Components

1. Data Management and Data Transfer

To run HPC applications in the AWS cloud, you need to move the required data into the cloud. There are several data transport solutions designed to securely transfer huge amounts of data. This overcomes issues like a long time for transfer, high network costs, and security concerns. Also, you can automate the movement of data between the AWS cloud and on-premises storage. There are options for establishing a private connection to the AWS from your premises. This increases bandwidth to provide more throughput, reduces the cost of the network, and provides a consistent network experience.

2. Compute & Networking

There are several compute instances types that can be customized according to your needs. It also handles monitoring your application and adjusting its capacity for maintaining a steady and predictable performance at an affordable cost. Also, setting up application scaling across multiple services for multiple resources takes a few minutes. Enhanced networking options from AWS allow achieving lower inter-instance latency and higher bandwidth. 

3. Storage

When looking for an HPC solution, you need to consider the storage options and cost. There are several flexible blocks, object, and file storage options in AWS services that allow permanent and transient data storage. It allows allocating storage volumes according to the size you need. You can store and access and data type over the cloud without doing a data migration project. Also, with AWS services, you can transfer your workload to the cloud from on-premises.

4. Automation and Orchestration

For using the infrastructure efficiently, you need to automate scheduling submitted jobs and the job submission process. AWS services allow you to run thousands of batch computing jobs through the dynamic provision of the computer resources on the basis of the requirements.

5. Operations and Management

As a system administrator, you are responsible for avoiding cost overruns and monitoring the infrastructure. There are several management and monitoring services that allow you to optimize utilization of resources, monitor the application, get a complete view of operational health, and respond to the performance changes.

6. Visualization

With the AWS services, you can easily visualize the engineering simulations’ results without moving huge amounts of data. Now, you can access the interactive applications remotely over a standard network and deliver application sessions to any workstation.

7. Security and Compliance

For running applications on the cloud, you need to have an understanding of regulatory compliance and security management. There are several quick-launch templates and security related services offered by AWS that helps in protecting data and customer privacy by putting strong safeguards in the AWS infrastructure.
