Amazon Web Services commonly known as AWS offers cloud computing services to public. In order to get a hang of cloud computing services in general and the important ones offered by AWS, we need to first understand cloud computing. Let’s begin.
In simple terms, Cloud computing is the delivery of on-demand computing services. The services that are offered range from applications to storage and processing power over the internet. The payment model is pay-as-you-go basis. The concept of cloud computing is not as complex as it seems. If you are using cloud computing services, rather than owning your own computing infrastructure or a data centre, you or your company can rent access to any computing resources they wish. These resources can be anything from applications to storage to a cloud service provider.
Benefits of Cloud Computing
There are many benefits of cloud computing that several companies and organisations are realising. One advantage of cloud computing is that there is no or less upfront cost. Cloud computing also reduces the complexity of owning and maintaining their own IT infrastructure. While companies use cloud computing services, they simply pay only for what they use and when they use it. The providers of cloud computing services earn profit by utilising significant economies of scale as they deliver the same services to a wide range of customers. Altogether, cloud computing replaces upfront capital infrastructure expenses with the help of an on-demand low-cost pay-as-you-go model.
Now that you have understood the core concept of cloud computing, it’s time to proceed to important AWS cloud services.
With the help of AWS, businesses no longer need to get into the hassles of planning and procuring IT infrastructures weeks or months in advance. Companies can instantly select any numbers of servers or other technologies required and it would be delivered to them in minutes.
Amazon Web Services provide a highly reliable, scalable, and low-cost infrastructure platform in cloud itself that powers thousands of businesses around the world. The services offered by AWS are compute, networking, storage, applications, databases and more. In the next segment, we would discuss some of the most important Cloud Services provided by AWS.
What are the Important AWS Cloud Services?
In this segment, we would discuss the various Cloud Services provided by AWS under important sections. Let’s get started.
Popular Amazon Web Services under the category of compute are Amazon EC2, AWS Lambda, AWS Elastic Beanstalk among others. Let’s discuss each of them in detail.
Amazon EC2 is an abbreviation for Amazon Elastic Compute Cloud. It is a cloud computing web service that basically provides secure and resizable compute capacity in the cloud. With the help of Amazon EC2, organizations can obtain and also configure virtual compute capacity in the cloud. Companies and organisation availing this service have an option to select from a variety of operating systems and resource configurations like memory, CPU, storage according to the requirements of their application as well as the company. The advantage of using Amazon EC2 is easy scalability, the capacity can be increased or decreased within minutes. The application can also automatically scale itself depending on the need and requirement. Companies can also use one or more than one (even thousands) server instances simultaneously.
Amazon EC2 is integrated with almost all AWS services like Amazon S3, Amazon RDS and Amazon VPC and hence it provides a complete, secure solution for all computing applications.
In this section, we are going to talk about another important AWS cloud service in the compute service that goes by the name of AWS Lambda.
AWS Lambda allows you to run code without the need of managing any server. The payment model is also very flexible as the company only needs to pay for the compute time they consume and not when the code is not running. This service helps an application to run with zero administration. All you need to do is to upload the code and AWS Lambda takes care of everything else that will run and scale your code. The code can be set up in order to automatically trigger from other AWS services or it can be called directly from any web or mobile app.
AWS Elastic Beanstalk
The last important service under the category ‘compute’ that we would discuss in this blog is AWS Elastic Beanstalk. This is basically a Platform as a Service (or PaaS) and it facilitates quick deployment of applications as it provides all the services that an application need. This service by Amazon supports a large range of platforms like Nodejs, Java among others.
The only thing you have to do is to upload your code and then AWS Elastic Beanstalk handles the deployment automatically. It handles everything right from capacity provisioning to load balancing to auto-scaling to application health monitoring. However, with AWS Elastic Beanstalk, you can also retain full control over the AWS resources that are powering your application. You can access the underlying resources at any time. Hence, all you need to do is to develop an application and deploy on Elastic Beanstalk.
Networking is an important concept if you have a web resource over the internet. In this segment, we would discuss some AWS cloud services under the category networking in detail.
Amazon VPC is basically a network environment in the cloud which allows you to create a private network within the AWS cloud. This AWS cloud service provides complete control of the network configuration. The normal networking configuration items such as IP address ranges, subnet creation, route table creation, network gateways and other security settings can be defined by the customers. Amazon VPC integrates with numerous AWS services like Amazon Relational Database Service (Amazon RDS).
Amazon Route 53:
Amazon Route 53 is another AWS cloud service under the category of networking. It is a highly scalable cloud Domain Name System (DNS) web service that gives developers and businesses a reliable and cost-effective way to route end users to Internet applications. It translates human readable names into the numeric IP addresses that computers use to connect to each other.
In this world of data, storage is an important concept. If you have a website or a web application, storage and handling of data is very crucial. In this segment, we would discuss some AWS cloud services under the category storage in detail.
Amazon S3 is also known as Amazon Simple Storage Service. It is also an object storage that is used to store and retrieve any amount of data from the web. Also, it has a simple web interface and designed to provide an infinite amount of storage delivered with high durability. Amazon S3 can also be used as a primary storage for cloud-native applications. It can be used as a target for backup and also for recovery of a disaster. With the Amazon’s cloud data migration, it is very simple to move large volumes of data into or out of Amazon S3.
Another AWS cloud service under this category is Amazon Glacier. It is a secure, durable and also a low-cost storage service solution. It is used for data archiving and backup for long term. The Data stored in Amazon Glacier is ideal for archiving as it takes several hours to retrieve.
In this world of clean and structured data, database is an important concept. If you have a website or a web application, database is crucial in order to handle of data is very crucial. In this segment, we would discuss some AWS cloud services under the category database in detail.
Amazon RDS is actually Amazon Relational Database Service. This service makes it easy to set up, operate, and scale a relational database in cloud. Amazon RDS is a cost-efficient solution with a resizable capacity. It automatically manages time-consuming database administration tasks and hence allows developers to focus on the code and other aspects of the applications as well as the business. With Amazon RDS, you can choose from six familiar database engines namely, Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server.
Amazon DynamoDB (Non- Relational Database):
Amazon DynamoDB is basically a non- relational database service. It is a fast and flexible NoSQL database service. It is perfect for all applications that need consistent, single-digit millisecond latency at any scale.
Amazon DynamoDB is a fully managed database and supports both document and key-value data models. Amazon DynamoDB is flexible data model which boasts a reliable performance and hence it is a great fit for mobile, web, gaming as well as many other applications.
