A Detailed Guide on AWS Development
Amazon Web Services is a cloud platform offered by Amazon Inc. which comprises various types of cloud computing products and services. It was launched in 2006 and has now become a major component of most of the eCommerce giants. Its revenue surpassed USD 62 billion in 2021. User-friendliness, high performance, security, and cost-effectiveness are some of the most rejoiced aspects for which AWS remains the top choice for web development services in the US. The way cloud computing has emerged as a possible solution for overall business requirements, businesses have started realizing its true potential and are looking forward to exploring its potential to the fullest.
A Brief Overview Of Cloud Computing
It’s an internet-based computing service where large groups of remote servers are networked together to facilitate centralized data storage and online access to other computer resources. It eliminates the need to plan for servers and IT infrastructure which was both a time-consuming and costly process. Cloud computing allows businesses to use shared computing and storage resources rather than creating infrastructure on their own. Here are some exceptional features that you get by opting for AWS cloud services:
- Using AWS services, businesses can provide and release resources on demand.
- Depending on the server load, resources can be scaled up or down automatically.
- Resources available on a network are highly secured to keep your data intact.
- AWS can enable a pay-as-you-go model where customers are charged based on per usage and types of resources they access.
Types of Clouds
Before you decide to leverage the fullest potential of AWS services for your business, you need to understand the types of clouds. This will help you in choosing the right cloud platform as per your business requirements.
- Public Cloud: When you opt for the public cloud, the third-party service providers offer resources and services to end-users through the internet. Your data and its security lie within the infrastructure owned by your service provider. This type of cloud platform is suitable for medium and small-scale businesses.
- Private Cloud: You will get almost the same features as the public cloud but you get complete control over the data and services. You have complete control over your cloud-based infrastructure and thus, security issues are minimized to a great extent.
- Hybrid Cloud: This type of cloud model is a perfect blend of both public and private clouds. You are free to run on public or private cloud depending on various parameters including the sensitivity of the data and applications, industry certifications, regulations, etc. This type of cloud model is best suitable for large-scale enterprises where massive data and its security remains a major issue.
Choosing The Right Cloud Service Model
There are three basic models among which you can choose with varying levels of shared responsibility between the service provider and you.
Infrastructure as a Service (IaaS)
Choosing IaaS refers to self-service that allows users to access and monitor hardware including processors, storage space, visualization services, etc. If you don’t have sufficient funds to create your infrastructure, choosing an IaaS cloud service model can prove to be the best option.
Software as a Service (SaaS)
The revenue for the global SaaS market was USD 152 billion in 2021. That is more than two-thirds of global public cloud services market revenue. The third-party providers offer end-user applications to you with some administrative capabilities like the ability to create and manage your users. You also get some customized features where you can use your corporate logos, colors, etc. It’s like a ready-made software product offered to you via the internet on a subscription basis.
Platform as a Service (PaaS)
In this cloud model, the service provider offers you services like databases, queues, workflow engines, emails, and many more. You can use these components to build your applications. The good thing is that services, resources, and data backup are all handled by the service provider so that you can focus more on the application’s functionality.
Understanding The Basic Architecture Of AWS
AWS EC2 stands for Amazon Web Services Elastic Compute Cloud which allows users to use virtual machines having different configurations to meet their business requirements. You get several configuration options, individual server mapping, pricing options, and a lot more.
Scalable Cloud storage
Amazon simple storage service is an object storage service offering exceptional scalability, data availability, security, and performance. Irrespective of the size of your business, you can use Amazon S3 to store and protect data for a range of use cases like data lakes, websites, mobile applications, backup, and enterprise applications.
This is an extremely low-cost storage service offered by Amazon where you can easily store your cold data. Cold data is often referred to as files that are not frequently accessed but still, you want to store them in case you need them later.
Amazon Elastic Block Storage
It’s a block-level storage solution that is used with EC2 cloud service to store persistent data. The data is stored on AWS EBS servers even after EC2 instances are shut down. You can attach, detach or scale data volumes using any EC2 instance.
Amazon Elastic File System
Amazon EFS offers a comprehensive and serverless elastic file system to use with AWS cloud services. This is built to scale on-demand requirements without disrupting applications, and it grows and shrinks automatically as you add or remove files.
Cloud Compute Resources
Amazon EC2 & How To Deploy An Environment On It
Amazon Elastic Cloud Compute is a core compute component that makes it easier for developers to offer secure and resizable compute capacity in the cloud. The process of scaling up and down servers is much simplified with this and can be easily integrated with several other services.
It follows the pay-as-you-go model where customers are charged for the time they have used the server. The best part is, that you can create a virtual server within 5 minutes and upload your application with VPC groups.
This service offers you virtual private services where you can choose among a variety of templates. It facilitates required infrastructure, a cost-effective way to maintain and manage the application, its scalability, and easy-to-setup options.
This compute service allows you to run code without managing the server. Lambda runs your code on the available infrastructure and you can run these codes virtually for any type of application or back-end service. It manages the entire compute fleet offering a balance of memory, CPU network, and various other resources to run your code.
Relational & Non-Relational Databases
A relational database is a pool of data sets having pre-defined relationships between them. Whereas, a non-relational database is a NoSQL database with several layers.
It allows you to install RDBMS of your choice, including MySQL, Oracle, SQL Server, and DB2 on an EC2 instance and can be easily managed as and when required. In short, it provides affordable relational databases in the cloud which are easy to use and manage.
Amazon Redshift is a fully-managed data warehouse service in the cloud. You can get started with a small chunk of data and then scale it up to a petabyte or more. This allows you to get fresh insights into your business based on this data.
AWS IAM-Working Components & Features
AWS IAM stands for AWS-Identity & Access Management which gives you complete control over AWS resources. You can create and control services regarding user authentication or can even limit access to certain people.
Features of IAM
- Shared access to AWS account
- Granular Permissions
- Multi Factor Authentication
- Identity Federation
- Free to use
- Password Policy
AWS Cloud Formation
This is a complete solution that allows you to create and manage multiple AWS resources in a text file without performing any manual action. You can easily provision and update them all in a predictable way to make it more comprehensive. All resources can be deployed easily using templates and you can reuse these templates to replicate your infrastructure in multiple environments.
AWS is the world’s most widely adopted cloud platform that businesses use to lower costs, become more agile, and innovate for the better.
