What is Cloud Computing With AWS?

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, offering over 200 fully-featured services from data centres globally. AWS (Amazon Web Services) is a platform that offers flexible, reliable, scalable, easy-to-use and, cost-effective cloud computing solutions. It includes a mixture of infrastructure as a service (IaaS), platform as a service (PaaS) and packaged software as a service (SaaS) offerings. AWS offers organization tools such as compute power, database storage and content delivery services. Aws courses are more in demand than ever.

History of AWS

  • 2002- AWS services launched
  • 2006- Launched its cloud products
  • 2012- Holds first customer event
  • 2015- Reveals revenues achieved of $4.6 billion
  • 2016- Surpassed $10 billon revenue target
  • 2016- Release snowball and snowmobile
  • 2019- Offers nearly 100 cloud services
  • 2021- AWS comprises over 200 products and services

This service was launched in 2006 from the internal infrastructure that Amazon.com built to handle its online marketing activities. AWS was one of the first companies to introduce a pay-as-you-go cloud computing model that scales to provide users with computing, storage or content delivery services.

Amazon Web Services offers many different tools and solutions for enterprises and software developers that can be used in data centres in up to 190 countries. Groups such as government agencies, education institutions, nonprofits and private organizations can use AWS services

What is Cloud Computing?

Cloud computing is an Internet-based computer service where large groups of remote servers are connected to a network to allow centralized data storage, as well as Internet access to computer services or applications.

Cloud computing with AWS is the on-demand delivery of IT resources over the Internet with pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data centres and servers, you can access technology services, such as computing power, storage, and databases, on an as-needed basis from a cloud provider like Amazon Web Services (AWS).

Using cloud computing, organizations can use shared computing and storage resources rather than building, operating, and improving infrastructure on their own.

Cloud computing is a model that enables the following features.

  • Users can provision and release resources on-demand.
  • Resources are accessible over a network with proper security.
  • Cloud service providers can enable a pay-as-you-go model, where customers are charged based on the type of resources and per usage.
  • Resources can be scaled up or down automatically, depending on the load.

Types of Cloud Compiting

There are three types of clouds − Public, Private, and Hybrid cloud.

Public Cloud

In the public cloud, the third-party service providers make resources and services available to their customers via the Internet. Customer’s data and related security are with the service providers’ owned infrastructure.

Private Cloud

A private cloud also provides almost similar features as a public cloud, but the data and services are managed by the organization or by the third party only for the customer’s organization. In this type of cloud, major control is over the infrastructure so security-related issues are minimized.

Hybrid Cloud

A hybrid cloud is a combination of both private and public clouds. The decision to run on private or public cloud usually depends on various parameters like the sensitivity of data and applications, industry certifications and required standards, regulations, etc

Cloud Service Models

There are three types of service models in the cloud − IaaS, PaaS, and SaaS.

IaaS Model:

IaaS stands for Infrastructure as a Service. It provides users with the capability to provision processing, storage, and network connectivity on demand. Using this service model, the customers can develop their own applications on these resources.

PaaS Model:

PaaS stands for Platform as a Service. Here, the service provider provides various services like databases, queues, workflow engines, e-mails, etc. to their customers. The customer can then use these components for building their own applications. The services, availability of resources and data backup are handled by the service provider helps the customers to focus more on their application’s functionality.

SaaS Model:

SaaS stands for Software as a service. As the name suggests, here third-party providers provide end-user applications to their customers with specific management skills at the application level, such as the ability to create and manage their users. Also, a certain level of customization happens as customers can use their company logos, colours, etc.

Advantages of Cloud Computing

Here is a list of some of the most important advantages that Cloud Computing has to offer −

Cost-Efficient −Building our own servers and tools is time-consuming as well as expensive as we need to order, pay for, install, and configure expensive hardware, long before we need it. However, using cloud computing, we only pay for the amount we use and when we use the computing resources. In this manner, cloud computing is cost-efficient.

Reliability − A cloud computing platform provides much more managed, reliable and consistent service than an in-house IT infrastructure. It guarantees 24/7 and 365 days of service. If any of the servers fails, then hosted applications and services can easily be transited to any of the available servers.
• Unlimited Storage − Cloud computing provides almost unlimited storage capacity, i.e., we need not worry about running out of storage space or increasing our current storage space availability. We can access as much or as little as we need.
• Backup & Recovery − Storing data in the cloud, backing it up and restoring the same is relatively easier than storing it on a physical device. The cloud service providers also have enough technology to recover our data, so there is the convenience of recovering our data anytime.
• Easy Access to Information − Once you register yourself in the cloud, you can access your account from anywhere in the world provided there is an internet connection at that point. There are various storage and security facilities that vary with the account type chosen.

Why Cloud Infrastructure Matters?

The AWS Global Cloud Infrastructure is the most secure, extensive, and reliable cloud platform, offering over 200 fully-featured services from data centres globally. Whether you need to deploy your application workloads across the globe in a single click, or you want to build and deploy specific applications closer to your end-users with single-digit millisecond latency, AWS provides you with the cloud infrastructure where and when you need it.

With millions of active customers and tens of thousands of partners globally, AWS has the largest and most dynamic ecosystem. Customers across virtually every industry and of every size, including start-ups, enterprises, and public sector organizations, are running every imaginable use case on AWS.

How AWS works

AWS is divided into different services; each can be configured in different ways based on user needs. Users should be able to see configuration options and maps for each AWS server.
