What is AWS cloud architecture?
In today’s digital age, storing and securing data has become a primary concern for every government agency, organization, or company. Hosting applications and managing data at a minimum cost is crucial to reduce the workload and ensure a smooth working platform.
To address these challenges, Amazon Web Services (AWS) offers cloud services designed to handle high web traffic and large amounts of data generated daily on applications or websites. AWS Cloud Architecture provides customers with the best practices, guidance, and recommendations to develop and maintain cloud solutions.
In this blog, we will explore the benefits and drawbacks of AWS architecture. First, let us understand why AWS is a popular choice for cloud computing services.
Benefits of using AWS
One of the biggest advantages of using AWS is that it is beginner-friendly, making it easy for users to create and deploy websites or applications. Additionally, it is a cost-effective solution as customers only have to pay for what they use. AWS does not require any long-term commitment or contract for payments, making it a flexible choice.
Moreover, AWS provides high performance, availability, scalability, and security. AWS architecture plays a vital role in enhancing the overall performance of the platform. It ensures that customers can use AWS to the fullest without any doubt.
AWS comes with many handy options, such as configuration servers, individual server mapping, and pricing. In the AWS architecture diagram, a custom virtual private cloud is created to secure the web application, and resources are spread across availability zones to provide redundancy during maintenance. Web servers are deployed on AWS EC2 instances, and external traffic to the servers is balanced by Elastic Load Balancer. Companies can add or remove instances and scale up or down based on dynamic scaling policies.
The AWS architecture makes it possible to offer the best services to clients based on web services technologies, adding or removing virtual servers, the selection of services, etc. AWS services and resources are available worldwide 24/7 and 365 days of the year where solutions are easily deployed according to clients’ requirements.
Different AWS Cloud Deployment models
The deployment models in cloud computing offered by AWS are an essential aspect to understand before opting for their services. AWS provides four deployment types, which are public cloud, private cloud, community cloud, and hybrid cloud.
The public cloud is ideal for organizations that have fluctuating demands and need to deploy something openly for public users on the network. On the other hand, a private cloud provides better security control and is generally used by independent companies. This model backs up all the data internally and externally with firewalls for hosting. If an organization seeks higher security, availability, and management, a private cloud is the best option to choose.
The community cloud model is where different organizations that belong to the same area or community manually share the cloud setups. For example, banks use the community cloud setup. The hybrid cloud model is a combination of both public and private clouds. In this model, resources can be easily provided via internal or external providers. Companies use a private cloud for data security but interact with users through the public cloud.
Different components of AWS cloud architecture
AWS architecture is comprised of several key components that provide various functionalities to its users. These components work together to enhance the efficiency and performance of web applications hosted on AWS. A simple AWS architecture diagram contains basic AWS services such as Route 53, Elastic Load Balancer, EC2, security groups, CloudFront, and Amazon S3 bucket. AWS architecture enables companies to store and retrieve data of various types using API calls.
Load balancing is one of the essential components of AWS architecture. It distributes traffic to EC2 instances across different availability zones, providing dynamic additions as well. AWS Elastic Load Balancer efficiently delivers load balancing, and its capacity can be adjusted based on various traffic conditions. Sticky sessions are also supported to achieve advanced routing services.
Amazon CloudFront is another component that mainly delivers website content, including streaming, static, and dynamic content, stored in global network locations. This component automatically requests the content from the closest location, enhancing performance.
Security is a key concern when it comes to cloud computing, and AWS architecture provides a secure environment for users to deploy their work. It offers a security grouping feature similar to inbound network firewalls, ports, source IP ranges, and protocols that need to be specified to reach EC2 instances. This feature provides a secure environment for users to store their data.
ElastiCache is a tool that is very handy in AWS when memory cache needs to be managed in the cloud. In-memory management, and clearing the cache plays a big role in reducing the load on the server. Frequently used information is easily cached to increase scalability, reliability, and performance.
Amazon RDS, which stands for Relational Database, offers services similar to MySQL and Microsoft SQL Server and is very user-friendly and easily accessible. It is an important component of AWS architecture that allows users to store, manage and retrieve their data.
Conclusion
In conclusion, AWS architecture is vital for any government agency, organization, or company that needs to host applications and secure and store data. AWS is a beginner-friendly platform that provides high performance, availability, scalability, and security. Its feature of memory management makes it very fast and resilient for clients to host websites and get affirmative results. Moreover, AWS provides end-to-end security and privacy to its clients by ensuring the three pillars of security—confidentiality, integrity, and availability—of the client data.
