With the capability to quickly increase the size of resources and use numerous services cloud computing is making it much easier for companies large and small to create and deploy Web Application Architecture.


In this blog we’ll look at the ways that cloud computing can alter the nature of web app architecture, and the many ways cloud computing can be utilized to create and deploy Web Application Architecture.


We will explore different types of cloud-based services, deployment models, and architectural models like microservices and serverless computing.


In addition, we will discuss the compliance and security issues associated with cloud computing to run web-based applications. We will also provide guidelines for protecting Web Application Architecture on the cloud.

Cloud Service Models

Cloud service models describe the various levels of service cloud providers provide their customers. The three most popular cloud models of service are:


1. Infrastructure-as-a-Service (IaaS) –

This is the most basic level of cloud service, where the provider offers customers access to virtualized computing resources such as servers, storage, and networking.


Customers can make use of these resources to create as well as run their own software. Examples of IaaS providers are Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).

2. Platform-as-a-Service (PaaS) –

This level of cloud service provides customers with a platform for developing, testing, and deploying applications.


PaaS providers offer a wide range of services, including databases, web servers applications frameworks, and databases that users can utilize to create their own applications.


A few examples of PaaS providers are AWS Elastic Beanstalk, Azure App Service along with GCP App Engine.

3. Software-as-a-Service (SaaS) –

This is the highest level of cloud service, where the provider offers customers access to a complete application that can be used over the internet.


SaaS providers host and manage the application, and users can access it using the web browser. Examples of SaaS providers are Salesforce, Office 365, and Dropbox.


Each model of cloud services has its own advantages and disadvantages, so it is crucial to select the most appropriate one based on the particular requirements of the Web Application Architecture.


IaaS is ideal for those who need complete control of their infrastructure and wish to develop and deploy their own software while PaaS can be ideal for those who prefer to concentrate on the development and deployment of their applications.


SaaS is the best choice for users who wish to utilize the software without worrying about the infrastructure.

Cloud Deployment Models

Cloud deployment models cover the different ways cloud service providers deliver their services to their customers. The three most popular types of cloud deployment are:


1. Public Cloud:

The Public Cloud is the most popular deployment method, in which cloud providers make their services accessible to the general public on the internet.


Cloud services offered by public cloud providers are usually priced per use and the customers don’t have to buy an additional system. Examples of cloud providers that are public comprise AWS, Azure, and GCP.

2. Private Cloud:

With this deployment type, the cloud service provider creates a cloud environment that is only available to a specific company.


The company can decide to host the cloud on its own premises or through the help of a third-party service. Private clouds give more options for customization and control however they can cost more than public clouds.

3. Hybrid Cloud:

This type of deployment blends both private and public cloud options, allowing businesses to benefit from the advantages of both.


For instance, an organization might choose to use a public cloud for data that is not sensitive while a private cloud is used to store sensitive information.


This model of deployment offers more flexibility and capacity, but also requires more coordination and management.


Each deployment model comes with each its advantages and disadvantages, so it is essential to pick the best one that meets the requirements of the web application.


Clouds that are public can be beneficial for those who don’t wish to invest in more infrastructure and are willing to pay for only what they need, whereas private clouds offer greater control and options for customization as well as hybrid clouds offer greater flexibility and flexibility as well as scalability.

Microservices Architecture

Microservices architecture is one method to build Web Application Architecture, where the application is split into small independent services.


Each service is accountable for a particular business function that is able to be designed, implemented, and scaled up independently.


This method allows for greater flexibility and flexibility and also faster development and deployment time.


In a microservices framework, it is common for each service to be constructed using a specific framework, programming language, or technology stack and is able to communicate with other services via APIs.


This gives more flexibility when choosing the best technology for the job. It also allows teams to collaborate on various services at the same time.


To implement the microservices model for cloud computing systems companies can make use of containers and containers orchestration tools like Docker or Kubernetes.


These tools enable the management and deployment of services in containers that can be easily scaled up and put into various cloud platforms.


Companies that have successfully implemented microservices-based architectures into their web-based applications include Netflix, Uber, and Amazon.


Netflix for instance employs more than 700 microservices to provide its streaming content. Uber makes use of microservices for its taxi-hailing as well as food delivery services.


Serverless Computing

The Serverless Computing model is a cloud computing system that a cloud service provider manages dynamically all the resources as well as the expansion of an application which allows developers to concentrate on writing code without having to think about the infrastructure.


In cloud computing, the cloud service provider abstracts the servers and charges the clients based on the number of functions called as well as the number of resources that are used.


This method has many advantages cost reduction as well as automatic scaling and more flexibility.


In order to implement serverless computing into Web application design, designers are able to utilize serverless computing platforms such as AWS Lambda Azure Functions and Google Cloud Functions.


These platforms let developers create and deploy functions that are triggered through events, such as HTTP messages, requests, as well as scheduled work.


Companies that have successfully integrated serverless computing into their web applications are Netflix, Airbnb, and Spotify. Netflix is one example.


It makes use of AWS Lambda to provide its recommendation engine. Airbnb utilizes servers-less computing for its search function.

Security and Compliance in the Cloud

Safety and conformity are essential concerns in the use of cloud computing to run web-based applications.


Cloud providers are accountable for the security of their infrastructures However, the customers remain accountable for the security of their own information and applications.


In terms of security, clients must make sure the data they store is secured both during transit and at rest.


This can be accomplished through secure protocols like HTTPS and SSL as well as by using encryption to protect data at rest as well as during transport.


Furthermore, the customer should ensure that their software is secure and is frequently updated to fix security concerns.


Compliance is a significant issue for companies that are subject to regulations like HIPAA, SOC 2, and PCI DSS.


Cloud providers might have compliance and certification plans in place however the customers need to ensure that their apps and data conform to the applicable laws.


This is accomplished through the implementation of security controls regular auditing and monitoring, while cooperating in conjunction with the cloud service provider, to make sure of compliance.


To ensure the security of web applications in the cloud, customers should adhere to best practices, such as:

  • Utilize multi-factor authentication to gain access control
  • Utilize a Web Application Firewall (WAF) to safeguard from common threats
  • Always back up and test disaster recovery strategies
  • Make use of central monitoring and recording to find and address security issues
  • Perform regular tests for security and penetration tests to find security weaknesses
  • Set up network segmentation and access control in order to limit access to sensitive information.
  • Utilize encryption to protect data during transport.

It’s crucial to realize that the protection and compliance offered by cloud computing are the shared responsibility of the client and the cloud service provider.


Therefore, it’s crucial to select a cloud service that has strong security features and certifications for compliance and to collaborate closely with them to ensure the application you use on the internet is secure and conforms.


In the end cloud computing has changed the way that web applications are created and developed.


With the capability to quickly expand resources and gain access to many different services cloud computing can make it much easier for businesses large and small to create and launch web-based applications.


The various model of cloud services, deployments, and even architectures like serverless computing and microservices offer various advantages and can be determined based on the specific requirements of the Web Application Architecture.


Security and compliance are important aspects to consider when using cloud computing to run Web Application Architecture.


Customers need to be sure their information is secure during transit as well as at rest, and their apps are not prone to weaknesses and are compliant with applicable laws.


To protect cloud-based applications users should follow the best practices, such as using multiple-factor authentication carrying out security assessments and penetration tests using network segmentation, access control, and using encryption to protect data at rest and while in transit.


Overall, the usage of cloud computing within the Web Application Architecture has provided many benefits, however, it is essential to keep in mind concerns regarding security and compliance.


If you choose the correct cloud model for service as well as the deployment model and architecture and follow best practices in safety and security, companies can effectively build and run Web Application Architecture on the cloud.
