No business can drive sales and promoter brand loyalty without making its website or mobile app deliver optimum user experience. The user experience delivered by a web application or mobile app depends on a number of factors. Servers are one of the critical factors affecting the website’s functionality, performance, and user experience. Hence, it is important for businesses to configure, scale, and manage the servers properly. Also, the businesses must monitor the servers continuously to detect and resolve performance issues on time.
Serverless architecture enables businesses to deploy and run their applications and service smoothly without a focus on configuring, scaling, maintaining, and monitor web server. Many enterprises nowadays opt for serverless architecture to deploy their applications and services on remote servers instead of onsite servers. They can even improve the application/service’s performance by availing multiple servers remotely over the internet. Hence, the businesses are not required to scale, maintain, and monitor onsite servers continuously.
They can avail the remote services through a category of cloud computing services - Function as a Service (FaaS). FaaS enables businesses to run applications and services smoothly without investing in on-premise servers. The cloud computing service further helps programmers to focus only on the application’s quality without worrying about server maintenance, monitoring, and security. They can further accelerate the development of large and complex software applications by creating microservice-oriented solutions.
1) No Need to Deploy, Upkeep, and Monitor Servers
The serverless architecture enables enterprises to run their software applications without investing in onsite servers. The cloud service providers make adequate server resources available to enterprises according to their specific needs. The servers need to be managed by the cloud service provider instead of the enterprise. Hence, the serverless architecture enables enterprises to develop, deploy, and update their applications efficiently in the cloud without managing servers.
2) Leverage Function as a Service (FaaS)
Serverless computing is enabled by a specific category of cloud computing services called Function as a Service (FaaS). FaaS enables enterprises to build and run software applications based on serverless architecture. At present, FaaS is provided by major cloud service providers like Amazon, Google and Microsoft. An enterprise can easily develop software based on serverless platforms like Google Cloud Functions, Microsoft Azure Functions, or AWS Lambda.
3) Focus on Writing Value Adding Code
In a conventional software development environment, a programmer has to focus on software deployment and management in addition to writing code. But serverless architecture enables programmers to focus extensively on writing value adding code without managing or marinating servers. The programmers can further take advantage of FaaS to write concise code that responds to specific events promptly. Hence, they are no longer required to build the application or API fully to accomplish specific tasks or add new functionality.
4) No Need to Scale the Entire System
Many enterprises switch to cloud platforms to enjoy enhanced scalability. But often programmers have to scale the entire application and system to meet additional business requirements or cater to growing traffic. Serverless architecture does not require programmers to scale the software application, system, or container completely. They can simply scale a single function up or down to accomplish the required scalability level.
5) Build Microservice Applications
The developers can further take advantage of serverless computing to simplify development of microservice applications. They can easily develop large and complex software into small services. Also, they are required to develop, manage, and scale the microservices individually without making changes to the entire software or system. FaaS further simplifies microservice application development by allowing programmers to divide each microservice into multiple functions.
6) Pay according to Execution Time
The serverless computing concept will help enterprises to curtail cost significantly. The enterprises are not required to pay for services. They have to pay only for invoking specific functions. Hence, the cost will vary according to the execution time of functions invoked by the application. As the application is not required to invoke all functions consistently, the businesses can curtail infrastructure costs significantly. The pay-as-you-use pricing model helps businesses to reduce operational cost in the long run.
Overall, the serverless architecture enables businesses to deploy and run applications and services smoothly without investing in on-premise servers. The enterprises can make their applications deliver optimal user experience by availing the required server resources from the cloud vendors based on the pay-as-you-use pricing model. Also, serverless computing helps developers to simplify development and deployment of large and complex applications without worrying about configuring, scaling, and maintaining servers.
