Serverless computing: An evolution of Cloud computing

Regain Competitive Edge through the Smallest Form of Compute

In today’s business landscape, the competitive edge is driven by technology with architectural design and deployment of software being at the core. This competitive advantage is determined primarily by the quality of interaction with customers and the service provided, and the effectiveness of internal business processes. With Serverless computing, enterprises get the required computing model to compete with the evolving challenges in their industry. As a result, software applications can be broken down into individual functionalities or functions in the serverless computing parlay (i.e. a micro-services based architecture). These functions are portable, cost-efficient and importantly not bound to a legacy infrastructure footprint.  

Setting the application functionalities apart from the supporting infrastructure gives an opportunity for enterprises for application modernization. In addition to this, it also removes all development constraints posed by legacy infrastructure. As a matter of fact, serverless can prove to be an exit strategy for enterprises from their legacy IT. 

Going Serverless has the Potential for Better Sales Opportunities and Customer Experience

Through different mechanisms and practices, serverless can play an important role in increasing customer experience and save on costs.  

Provider Manages Server Hardware

You don’t need to purchase servers or hire resources to look after them. You only need to monitor your applications are working harmoniously with the servers.

Accommodate Scaling

Scalability is described in the previous section. Since you are only paying proportionally to usage the spike in traffic is compensated by low usage. So your bills may be more or less the same.

Rapidly Deploy Functions

You only need to compile your code, zip it and upload to the serverless provider. It makes your development process agile because of rapid iterations and deployment. You don’t need to write any scripts (Puppet/Chief or Start/Stop scripts). You are not spending on any system administration or on containers.

Optimization Of Code

Optimizing code can increase the agility of a program. This reduces the operational cost related to your program. For example, if your usual program takes 1 second to execute an operation with the hardware server, it may now take 200 ms to perform the same operation handing you an 80% savings in costs.

Optimize Productivity Of Developers

Developers can write code mostly for the programs and not for the server. They can direct their efforts to innovate or improve their core programs.

Reducing Carbon Footprint

When there are no servers there is no energy required to keep them running. You are saving not just in your energy bill but also the environment.

Improving Overall Costs

With more logic functions coming to the front end, paying when only using the server (not when they are idle) and rapidly deploying applications, you increase overall savings in costs. Rapid deployment and faster program response will lead to an improved customer experience.

Nous Offers Serverless Architecture with Function-as-a-service 

Reduction In Costs

Reduction In Costs

Serverless architecture helps enterprises in saving costs in terms of computing power. This helps businesses in eliminating the complexity and demands of supporting and maintaining systems. With no requirement of always-on servers, operational costs get reduced drastically.

Infinite Scalability And Built-in High Availability

Infinite Scalability And Built-in High Availability

In traditional architecture, scaling can be expensive. In case of dedicated servers, during an inquiry overload, applications can get overwhelmed and crash. Serverless, enables applications to automatically have access to the required amount of infrastructure support to respond to all the inquiries.

Fast-Paced Delivery And Less Ops

Fast-Paced Delivery And Less Ops

Where traditional servers take months, the serverless architecture allows developers to create in days and weeks. Serverless architecture has established infrastructure, program logic, and runtime components. Therefore, the tasks of setting up servers, configuring environments, clustering, that come with a traditional system, get eliminated.

Key Architectural Serverless Principles

Program Logic

AWS Lambda is a computing service with which you run code without provisioning or managing servers.

Data Persistence

RDS is a relational database. It simplifies setup, operation, and scaling of a relational database.

DynamoDB is a highly scalable NoSQL database.

Authentication and Authorization

Amazon Cognito provides a tool for all your authorization and authentication needs.


SNS and SES is a messaging service that simplifies decouple and scale microservices, distributed systems, and serverless applications.

Content Delivery

Cloudfront CDN content delivery.

Stream Processing

Kinesis for processing your streaming data. This function helps to build custom applications that process or analyze streaming data for specialized needs.

Service Delivery

With AWS API Gateway tools and services we can create, publish, maintain, monitor, and secure their APIs at any scale.


Cloudwatch based monitoring services help to collect and track metrics, collect and monitor log files, set alarms.

Migration to a Serverless Architecture

Depending on the specifics of your application we offer Migration to a Serverless architecture, leading to a huge improvement in scalability and performance, and a significant decrease in cost.

Creating Dynamic Frontends

As functions are stateless and persist only for a limited duration, it is recommended to write single-purpose codes for function. This limits the execution time of a function. This has a direct impact on cost. Single-purpose codes are easier to test, deploy and release. Thus, improves enterprise agility.

Designing Push-based Patterns

Designing push-based and event-driven architecture patterns where a chain of events propagates without any user input. It imparts scalability to an architecture.

Incorporating Required Security Mechanism

Appropriate security mechanisms must be incorporated at the API Gateway layer and also at the FaaS layer. These security mechanisms include features like access controls, authentication, identify and access management, encryption and establishing trust relationship etc.

Monitoring Serverless Infrastructure

With the help of AWS services, we monitor and audit cloud-based systems or applications. To efficiently monitor the performance of systems or applications, using serverless architectures.

Identify Performance Bottlenecks

On-going measurement of performance bottlenecks in terms of identifying which functions are slowing down a particular service is critical to ensure optimal customer experience.
