Understanding the architecture of AWS, key components, and main use of cases


Amazon Web Services, known as AWS, is the leading platform in the cloud computing market.

It offers over 200 services that make it easy, fast, and cost-effective for organizations to build solutions. With these services, organizations can configure solutions by referencing AWS Architecture.

What is the AWS architecture, and what is its purpose?

AWS architecture is a process that involves the planning, design, and implementation of AWS resources in a cloud infrastructure. 

The AWS аrсhіtесturе represents several components (front-end, back-end, and network infrastructure. It serves as a blueprint to help companies or organizations see the development work in its entirety, ergo, view how the elements interact at a glance.

Why is it important to understand the architecture of AWS? 

Understanding the AWS architecture helps you see the need to have and use it for your cloud computing solutions. 

  • For starters, organizations that employ the services of AWS gain access to the internal state of the platform through the AWS infrastructure. 

  • Understanding the architecture of AWS also means you gain access to complex ideas and understand the technical concepts that may be unfamiliar. 

  • In addition, understanding this architecture enables you to make decisions about designs.

What are the five pillars of AWS architecture?

The pillars of AWS infrastructure are important to every developer that employs the services of AWS. The 5 AWS architecture pillars are as follows:

  1. 1

    Security

    It describes data protection, systems, etc., on the cloud. This security pillar also involves 6 areas – data protection, infrastructure protection, foundation, identity and access management, detection, and incident response. 

  2. 2

    Performance Efficiency

    With cloud computing, there are often cases of technological evolution and changes in demand; performance efficiency helps you focus on using computing resources to maintain efficiency and meet requirements. 

  3. 3

    Reliability

    Reliability refers to the ability of a system to perform its function correctly and consistently under different conditions. This reliability pillar also includes testing a workload via its lifecycle. 

  4. 4

    Cost Optimization

    You can use a workload cycle to improve and refine workloads. As a result, you can build cost-effective workloads while maximizing return on investment. Also, tracking the finances used for a particular business is easier.

  5. 5

    Operation Excellence

    Because there are preparations for operational excellence, you’d need to be up-to-date with organizational structure and priorities. It will help you in operating and responding to risk.

Ignoring the AWS 5 Pillars might result in difficulty in developing a solution that meets your expectations and objectives.

On the other hand, working with these pillars gives you a consistent way to analyze architectures and develop ideas that will grow over time.

What are the key components of the AWS architecture?

  • Amazon CloudFront

    Amazon CloudFront is mainly used to drop content on websites directly. Amazon CloudFront content can be dynamic, fixed, or streaming, utilizing worldwide network locations. 

  • Elastic load balancing

    This component boosts the applications and servers’ performance and efficiency. It works to reduce and enable load balancing by rationalizing traffic automatically.

  • Amazon RDS

    Amazon RDS, or Relational Database Service, helps provide access comparable to MySql (Microsoft SQL Server). Moreover, it is available globally, making its usage possible from all over the world.

  • Amazon ElastiCache

    The cache is essential for memory management and efficiently minimizing service loads. In addition, it increases the architecture.

AWS Architecture with Web, App, DB Tier: How does it work?

AWS architecture works with 3 tiers- web (or presentation), application, and database. Here’s how AWS architecture work with these tiers:

  • When a user loads the app web address, it is confirmed by Route S3, a DNS (Domain Name System) management system.

  • After that, the request іѕ forwarded to the load balancer, which distributes the traffic to multiple EC2 instances running the web application. 

  • An auto-scaling group manages these instances to ensure high availability and scalability. 

  • This traffic will finally reach the web and application tiers before connecting to the database tier.

  • For the backup solution, one S3 Bucket links to the Web and database tiers to store static data such as photos and GIFs.

  • The CloudFront Content Delivery Network will receive the request to view the content.

  • Moreover, this full architecture is compatible with additional services, including Cloud Watch, Amazon Dynamo DB, SES, AWS SNS, and others.

What are the benefits of AWS Architecture?

  • Assessing Potential impact

    The rapid changes often experienced in cloud environments can bring positive or negative impacts. You can employ procedures and processes to address and assess the potential impacts of said changes.

  • Consistency

    Every team member stays on the same page; this helps your organization maintain consistency. It also means that everyone stays on course even when roles change and new people are hired.

  • Reduced risks

    AWS architecture allows you to conduct periodic reviews that help locate potential risks before they become full-blown problems. When problems arise, you can easily fix them by assessing critical workloads.

  • Cloud-native

    The cloud-native approach goes beyond making existing applications available from a hosted cloud service, as it also helps you maintain focus on the cloud environment from the beginning.

Conclusion

With the AWS architecture, you can deploy applications without manually managing, provisioning, or scaling servers. Thus, businesses can easily scale their resources, improve data processing requirements, reduce operating costs, and solve latency issues.

FAQ

What is a 2-tier architecture in AWS?

This is just a business-like relationship between the user and the server. The user is the first tier, and the server is the second tier. This is the easiest and most commonly used structure.

Where are AWS architecture diagrams?

AWS diagrams are simply pictures or illustrations showing or depicting an AWS architecture’s workflow.

What is the architecture of AWS S3?

This is like the ultimate space where data is stored. It can stay for over a year and be retrieved anytime needed.

What framework is AWS?

AWS is more of a platform because a platform deals with both software and hardware systems, unlike a framework that deals with just software. It also deals with java open source in terms of library and simplified development.
