Role of Serverless Computing for Cloud Modernization

Serverless technology redefines the way in which business enterprises create, use, and manage different cloud-native apps. As businesses look for cost-effectiveness, scalability, and agility in the latest years, serverless computing is becoming a popular option to create and deploy different apps.

Thus, they are regarded as the suitable option to manage the dynamic workloads, short functions, connecting to different external events, linked with various services, and variable scaling needs, which are known to operate statelessly. It is equipped with the capability of abstracting the underlying infrastructure. Thus, it is recognized as a popular tool to accomplish modern application development.

What is serverless computing?

Serverless computing is regarded as a rising trend in the cloud computing sector. It provides a bunch of benefits that regular server-based computing fails to offer. Such benefits include improved scalability, increased performance, and reduced costs. Thus, the developers will be able to execute the code without the need to manage the servers.

Reasons to opt for serverless computing

The serverless model has become the latest buzzword as it decreases the need for business enterprises to have their staff dedicated to different concepts, like systems administration, upgrades and patching, service level agreements, low-level performance in databases and operating systems, and system uptime.

 In the security realm, the serverless architecture provides a bunch of advantages. With the underlying infrastructure abstraction, the serverless platforms decrease the attack surface, as no persistent servers are available for the targeting of the attackers. Such kind of transient nature assures that the potential threats are not capable of establishing the constant foothold.

The cloud service providers can manage and patch different serverless environments. It indicates that the underlying software gets updated frequently, which helps address different vulnerabilities without the need for developer interruption. It assures that the foundation platform becomes resistant to different known problems.

The serverless platforms are known to emphasize different fine-grained permissions. It provides the optimum choice for developers to apply the least privilege principle. Thus, every function gets tailored specifically so that it includes the necessary permissions, thereby restricting the potential damage as a specific function gets compromised.

Serverless computing happens to be a simple solution, which allows the developers to concentrate on the code in place of infrastructure. Thus, it boosts time to market, thereby reducing vendor lock-in. It provides scalability, unprecedented cost savings, and developer efficiency, thereby making it a promising trend for cloud computing.

Pros of serverless computing

Let’s discuss some of the benefits of serverless computing for cloud modernization!


By choosing serverless computing, the resources for app modernization get scaled up and down automatically depending on the demand. Thus, it assures effective use of the resources and higher flexibility.

Reduced costs

Frequently, cloud technology users pay for unused space and idle computing, which is essential to decommission and commission the different resources. The serverless technology makes use of auto-scaling for resource provisioning.

Best use of different resources

The TCO, or total cost of ownership, reduces as you move to serverless cloud computing. Thus, you will be capable of reallocating the resources to boost the activities that affect business growth.

Operational resilience

The business enterprise finds an increase in operational resilience as there are fewer and no unplanned outages and downtime, leading to reduced time to repair.

Boosting productivity

Serverless cloud application modernization provides an ideal opportunity for IT developers and teams, thereby delivering enhanced applications and features within a shorter timeframe. Thus, it boosts productivity. As the developers opt for Function as a Service, they do not require writing the complicated backend code. Thus, they can create simpler functions, which are essential to executing a singular task. Henceforth, you will be capable of streamlining the application development while using the backend as a service.

Quicker time to market 

The developers will be capable of adding and modifying the code without the need to worry about the complicated deployment process, using serverless technology. As there are fewer operational dependencies on every development cycle, they will deliver enhanced functionalities in less time, thereby boosting the time to market. Thus, they will be capable of deploying the different cloud-native applications within certain days and hours instead of months and weeks.

Decreasing administrative overhead hassles

The serverless service providers adopt the task of managing different servers along with the backend operations. It assures the development teams to concentrate on app development in place of serverless management and maintenance. Hence, you will be capable of decreasing operational spending, infrastructure costs, and the hassles of handling them with the use of fully managed services by choosing serverless technology.

Quicker deployment

The serverless technology allows the development teams to deploy workloads and applications such as stream processing, data processing, and parallel processing without the configuration and setting up of different servers.

A wide assortment of businesses harness the serverless architecture, which allows you to achieve agility during the creation, iteration, and testing of different apps. The serverless apps allow you to scale up automatically and seamlessly faster so that you can accommodate sudden upsurges in traffic. Such applications will scale down automatically, as there are fewer concurrent users.

Serverless computing technologies allow developers to create apps as their first serverless strategy. Shifting to serverless app development principles offers agility across the application stack. Every cloud service provider is created with a range of different serverless computing services and technologies in different stack layers, like application integration, compute, database, data stores, analytics, and monitoring.

Serverless technology has become the latest buzzword for cloud native apps as it bridges the gap between the data-driven capabilities of the cloud and the limited computational power of Edge. Such architectures reduce the limitations of one another, thereby creating the latest possibilities for the future. Serverless technology happens to be the latest evolutionary phase of network architecture and computing development. It happens to be a fledgling technology that is extremely useful for the earlier phases of development. Serverless computing happens to be the fastest-growing part of the application modernization service, which cannot be ignored by startups and other enterprises. Thus, you will be capable of spending less time on the cloud infrastructure.
