In 2006, Amazon Web Services, (AWS) began offering IT services to the public in the form of web services commonly known as cloud computing. One of the key benefits of cloud computing is that it replaces upfront capital infrastructure expenses with an on-demand low-cost pay-as-you-go model. AWS made businesses no longer need to plan for and procure IT infrastructures weeks or months in advance. Instead, they can instantly select any numbers of servers and other technologies needed for them and it is delivered to them in minutes. Today, AWS provides a highly reliable, scalable, and low-cost infrastructure platform in the cloud that powers hundreds of thousands of businesses in more than 190 countries around the world.
AWS services are typically grouped into different categories like compute, networking, storage, applications, databases, and analytics
Important Cloud Services provided by AWS
The Important Cloud Services according to various categories that are provided by AWS are given below :
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It allows organizations to obtain and configure virtual compute capacity in the cloud. You can select from a variety of operating systems and resource configurations like memory, CPU, storage that is required for your application. Amazon EC2 enables you to increase or decrease capacity within minutes. You can use one or hundreds or even thousands of server instances simultaneously. Because this is all controlled with web service APIs, your application can automatically scale itself up and down depending on its needs. Amazon EC2 is integrated with most AWS services, such as Amazon Simple Storage Service (Amazon S3), Amazon Relational Database Service (Amazon RDS), and Amazon Virtual Private Cloud (Amazon VPC) to provide a complete, secure solution for computing applications.
AWS Lambda allows you to run code without managing servers. You pay only for the compute time you consume and there is no charge when your code is not running. With AWS Lambda, you can run code for any type of application with zero administration. Just upload your code, and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services, or you can call it directly from any web or mobile app.
AWS Elastic Beanstalk:
AWS Elastic Beanstalk is a Platform as a Service that facilitates quick deployment of your applications by providing all the applications services that you need for your application. Elastic Beanstalk supports a large range of platforms like Node js, Java, PHP, Python, and Ruby. So, you can develop your application to meet your requirements and simply deploy on Elastic Beanstalk. You can simply upload your code, and AWS Elastic Beanstalk automatically handles the deployment, from capacity provisioning, load balancing, and auto-scaling to application health monitoring. At the same time, you retain full control over the AWS resources powering your application and can access the underlying resources at any time.
Amazon VPC is your network environment in the cloud. It allows you to create a private
network within the AWS cloud that uses many of the same concepts and constructs as an on-premises network. Amazon VPC also gives you complete control of the network configuration. Customers can define normal networking configuration items such as IP address ranges, subnet creation, route table creation, network gateways, and security settings. Amazon VPC is an AWS foundational service and integrates with numerous AWS services. For instance, Amazon EC2 instances are deployed into your Amazon VPC. Similarly, Amazon Relational Database Service (Amazon RDS) database instances deploy into your Amazon VPC, where the database is protected by the structure of the network just like your on-premises network.
Amazon Route 53:
Amazon Route 53 is a highly available and scalable cloud Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost-effective way to route end users to Internet applications by translating human readable names, such as www.geeksforgeeks.com, into the numeric IP addresses that computers use to connect to each other.
Amazon S3 (Simple Storage Service):
Amazon Simple Storage Service (Amazon S3) is object storage with a simple web service interface to store and retrieve any amount of data from anywhere on the web. It is designed to provide an infinite amount of storage and it is delivered with 99.999999999% durability. You can use Amazon S3 as primary storage for cloud-native applications as a target for backup and recovery and disaster recovery. It’s simple to move large volumes of data into or out of Amazon S3 with Amazon’s cloud data migration options. Once data is stored in Amazon S3, it can be automatically tiered into lower cost, longer-term cloud storage classes like Amazon S3 Standard – Infrequent Access and Amazon Glacier for archiving.
Amazon Glacier is a secure, durable, and extremely low-cost storage service for data archiving and longterm backup.Data stored in Amazon Glacier takes several hours to retrieve, which is why it’s ideal for archiving.
Amazon RDS (Relational Database Service):
Amazon Relational Database Service (Amazon RDS) makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business. Amazon RDS provides you six familiar database engines to choose from, including Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server.
Amazon DynamoDB (Non Relational Database):
Amazon DynamoDB is a fast and flexible NoSQL database service for all applications that need consistent, single-digit millisecond latency at any scale. It is a fully managed database and supports both document and key-value data models. Its flexible data model and reliable performance make it a great fit for mobile, web, gaming, Internet of Things (IoT), and many other applications.
