Benefits of Serverless Computing and Event-driven Architectures

With emerging cloud computing technology, thankfully, enterprises can remove the headaches of infrastructure requirements. Instead of relying on your server, you can rent the server from open-source applications. You can explore the benefits of serverless computing, which can help you save expenses and add to your development convenience.

When developing an application, application architecture plays a crucial role. At the same time, you reflect on the design and structure of the application. “who will manage” is an important question when discussing cloud computing. Managing your architecture can be challenging, but not if you have switched to serverless computing. As a result, your custom software development company can spare their precious time in developing a platform rather than managing it. AWS serverless computing can help you integrate applications while running code and managing the data without requiring a server. This blog post will explain the benefits of serverless computing and event-driven architectures so that you can make a smart decision to switch to AWS.

What Does Serverless Computing Mean?

Serverless computing is a kind of AWS cloud computing allowing your enterprise to use backend infrastructure on a pay-as-you-go option. In other words, you do not need to buy the whole server bandwidth; rather, you can pay according to the processing power you utilise as per need. By opting for this, you can eliminate architecture responsibilities and focus on more important tasks such as running code and testing applications. You set yourself free from provisioning, maintaining, and scaling your application as it is automatic. 

With the recent growth of cloud computing as the latest technology, Amazon Web Service (AWS) has taken a profound shift in the curve, covering factors like low cost, improved scalability, and enhanced developer productivity. A recent study by O’Reilly has indicated that 40 per cent of organisations have already shifted to serverless architectures. If we want to unlock the true potential of the AWS cloud, then we need strategies for successful migration.

For serverless computing, you need to purchase a flexible pay-as-you-go option where your provider will handle all your servers. This is similar to switching from a phone data plan to a fixed schedule which limits usage. When we talk about AWS serverless computing, we can observe it as a fast-growing platform where you can eliminate the infrastructure management and remove the overhead costs. With built-in service integration, the possibility of configuring the application becomes easy. Serverless architecture benefits enterprises by empowering their tech products and facilitating time-to-market and low infrastructure cost opportunities. 

Advantages of Serverless Computing 

Serverless technology can be understood in two definitions.

First is Backend as a Service (BaaS), wherein the features with complex UI are applicable for monitoring backend features. Third-party vendors monitor these. Secondly, at the back of the stick is Function as a Service (FaaS), providing scalability to the server-side architectures. Under this, the event is triggered on functional demand. 

Here are some of the benefits of serverless architecture:

 1. Easy to Deploy

Serverless computing technology is easy to set up in a much shorter time. Usually, it takes weeks or even months to set up an application. But with serverless architecture, you can do it in a few days as there is no infrastructure dependency. You just need to run the code and deploy it immediately without wasting much time. 

 2.More Time to UX

The purpose of your application development is to make customers happy, and obviously, they do not care about what infrastructure you are using. The only thing that matters is what they see in the front end. So you should focus on resource allocation, which meets the criteria for a great customer experience and forget what is happening in the backend.

 3. Better Scalability and Latency 

Serverless computing benefit users by developing flexibility and scalability to accommodate the changes in current scenarios. IT consultancy suggests that having access points on a global scale, this agile infrastructure can be scaled from any corner of the world without worrying about performance. 

 4. Reduced Architecture Costs

Outsourcing the capability of managing and maintaining servers from outside is a great idea for reducing infrastructure costs. Serverless computing helps reduce the cost associated with power and supports internal architecture administration. Sometimes, the price will not be much cheaper, depending on your use case. 

 5. Makes Your Coding Process Efficient

With the traditional servers, you would run it all the time. Serverless technology can help you streamline the coding process as you utilise the service as requested. Likewise, there is less wastage of resources, and you no longer worry about scaling your service. Capacity planning, infrastructure maintenance, and DevOps no longer concern you. 

What is AWS’s Serverless Compute Service?

Amazon Web Service (AWS) is a platform for running applications without the hassle of managing complex servers. You can run, manage and integrate your applications for effortless code writing. It builds on a pay-per-use model for optimizing your infrastructure cost at its best. It is also known as AWS Lambda, which has built-in scalability to use the servers as per the triggered event. Since it has pay-per-use pricing, you pay only for the computing time consumed by your code. There are no upfront costs or fees for idle resources. You are billed in increments of 100 milliseconds, paying for the exact compute time used.

What is Event-Driven Architecture?

As the name suggests, event-driven architecture is the application component to be used as per the events. It is a collection of loosely coupled services that operate together to attain a common goal. Let’s break the term down to understand it better.

Events are the changes detected in a system that can be system-generated or human-generated. Various sources, such as user interactions, system processes, sensors, or external systems, can generate these events. Examples of events include user clicks, data updates, messages received, or errors detected. 

Architecture is defined as a set of loose services that act in real-time 

The key features of event-driven architecture include event resources, event brokers, event consumers, and event-driven workflow.

Benefits of Event-Driven Programming

Event-driven architecture offers a platform for auto-scaling, becoming a modern choice for building a responsive system. It can provide you with opportunities for improving user experience by creating and testing new services. The key advantages include:

 1. Loose Coupling and Modularity 

In event-driven programming, events are loosely coupled, wherein each component has no control over the other features. This makes them modular, allowing each component independence during system interaction. It becomes easier to manage the individual element and work on updates that might impact the entire system.

 2. Flexibility and Scalability

Event-driven architecture provides flexibility in integrating new components or systems into an existing architecture. New event sources or consumers can be added without disrupting the system if they adhere to the defined event structure. You can also scale your application easily, as all components are isolated. 

 3. Connect with Your Multi-Cloud Landscape 

Since the components like message brokers and event consumers can be connected to the cloud, this event-driven programming can do wonders by clicking on unique services. You can collaborate with different AWS’s largest cloud providers to develop an amazing set of services supporting your business needs. 

 4. Real-time and Reactive Systems

This event-triggered architecture is well-suited for building real-time and reactive systems that respond instantly to events. Events can be generated from various sources, such as user interactions, sensor data, or external systems, and the system can react to them in near real-time. 

 5. Asynchronous and Non-blocking Processing 

Under this architecture, the reaction of one component does not depend on the other element. This is known as asynchronous processing, which increases the possibility of improved performance and allows multiple systems to work concurrently, leading to faster response time.

Overall, a serverless framework is a good option for scalability, low cost, and high uptime. AWS cloud computing offers serverless computing and event-driven architectures that fit the needs of modern enterprises. Suppose you are looking to switch to serverless computing. In that case, you must consider the benefits of serverless computing and event-driven architecture so you do not lag in making a smart decision.
