AWS 07-Days Challenge, Day-01
Introduction -
The future of cloud computing is being revealed here, in the world of Amazon Web Services (AWS).
Businesses must negotiate a terrain where innovation, scalability, and agility are paramount in today's digital landscape. AWS becomes the shining light in this tech-driven revolution, revolutionizing how businesses use the enormous potential of the cloud.
A Brief Overview of Amazon's History
Back in the early 2000s, when Amazon was already transforming e-commerce, AWS was first conceptualized. With the introduction of Amazon Simple Storage Service (S3), AWS's first cloud service, users could now store and retrieve data in the cloud in a completely new way.
AWS quickly increased the range of services it offered as the cloud computing industry changed. When Amazon Elastic Compute Cloud (EC2) first launched in 2008, users could rent virtual machines to run their own applications. This was a huge advancement in the field of cloud computing, igniting creativity and changing how companies viewed computer resources.
With the introduction of numerous services, including databases (Relational Database Service, DynamoDB), networking (Virtual Private Cloud), and cutting-edge technologies (machine learning, IoT, and AI), Amazon continued its explosive ascent.
What is AWS?
Amazon Web Services is a suite of cloud services that offers virtually limitless possibilities. It was developed by the tech giant Amazon and is not just a platform. With a vast array of services to meet various business requirements, AWS provides everything from computing power to storage solutions, databases, machine learning, IoT, and more.
Different Pricing Models offered by AWS
Pay-as-you-go
With AWS, you only pay for what you use, helping your organization remain agile, responsive, and always able to meet scale demands.
Pay-as-you-go pricing allows you to easily adapt to changing business needs without overcommitting budgets, improving your responsiveness to changes. With a pay-as-you-go model, you can adapt your business depending on need and not on forecasts, reducing the risk of overprovisioning or missing capacity.
By paying for services on an as-needed basis, you can redirect your efforts toward innovation and invention, reducing procurement complexity and enabling your business to be fully elastic.
Save when you commit
Savings Plans are a flexible pricing model that provides significant savings on your AWS usage. This pricing model offers lower prices on AWS compute and AWS machine learning. Savings Plans offer savings over on-demand in exchange for a commitment to use a specific amount (measured in dollars per hour) of an AWS service or a category of services for a one- or three-year period.
You can sign up for savings plans for a 1- or 3-year term and easily manage your plans by taking advantage of recommendations, performance reporting, and budget alerts in the AWS Cost Explorer.
Pay less by using more
With AWS, you can get volume-based discounts and realize important savings as your usage increases. For services such as S3 and data transfer OUT from EC2, pricing is tiered, meaning the more you use, the less you pay per GB. In addition, data transfer is always free of charge. As a result, as your AWS usage needs increase, you benefit from the economies of scale that allow you to increase adoption and keep costs under control.
As your organization evolves, AWS also gives you options to acquire services that help you address your business needs.
For example, AWS’ storage services portfolio offers options to help you lower pricing based on how frequently you access data and the performance you need to retrieve it. To optimize your savings, choose the right combinations of storage solutions that help you reduce costs while preserving performance, security, and durability.
Types of clouds:
Public/on- Cloud
In a public cloud, everything is stored and accessed through the internet. This deployment system allows anyone with proper permissions to access some of the applications and resources. The most exciting part about the public cloud is that you own none of the components present in it, be it the hardware, software, or application. All the components here are managed by the provider. Amazon Web Services and Microsoft Azure are two prominent examples of the public cloud
Private/premises Cloud
A private cloud is used exclusively by organizations, which they can run locally or choose to outsource to other cloud service providers. This infrastructure runs strictly on a private network, which means that people present on the network can only access it. VMware cloud and some of the AWS products are some examples of private cloud
Hybrid cloud
is probably the most fascinating form of cloud computing that contains the functionality of both public and private clouds. Organizations using the hybrid cloud can choose to keep some of their data locally and some on the cloud. NASA is the best-known example of an organization that uses a hybrid cloud.
Multi cloud
Multi-cloud is a cloud approach made up of more than one cloud service from more than one cloud vendor—public or private.
For example, your enterprise invests in expanding its cloud infrastructure. You've moved from bare-metal servers to virtualization-based workloads, and now you're evaluating public cloud options—not for everything, but to support a specific customer-facing application with highly variable use rates. After some research, you find the public cloud provider that has the right blend of service-level agreements (SLAs), security protocols, and uptime to host your custom application. You’re happy with your choice. But eventually, customers start asking for features that are only available through a different vendor’s proprietary app. Integrating these features into your custom app requires that you not only purchase the vendor’s app but also host the app in that vendor’s proprietary public cloud—a solution that allows both apps to scale with demand.
Different layers of cloud service delivery
On Premises
On-premises implies that you, as an organization, must handle all aspects of running the data center and obtaining the data needed for your application. An example of this would be the banking industry.
Iaas (Infrastructure as a Service)
This category consists of IT infrastructure that you can rent from a cloud provider on a pay-as-you-go basis, including servers, networks, and others. The best part about this service is that you have access to the services you provisioned, and some grant you root-level access as well. EC2, or the AWS Elastic Compute Cloud, is an excellent example of IaaS
PaaS (Platform as a Service)
In this model, you are supplied with a pre-built platform from the cloud providers, where you can deploy your codes and applications. You only need to manage the codes and the applications, not the infrastructure. AWS Elastic Beanstalk is an example of a PaaS cloud
SaaS (Software as a Service)
Here, the cloud providers offer you the end product, which could be an application or software that you can buy directly through a subscription. As a part of this service, the client maintains control of the software environment but does not maintain any equipment. There are some products from AWS and Microsoft Azure that provide SaaS.
Why Choose AWS?
Worldwide Infrastructure: A global network of extensive data centers guarantees low latency and high availability.
