Serverless computing also referred to as Function-as-a-Service (FaaS) is replacing traditional cloud-based or server-centric infrastructure. It has become more common with Amazon releasing AWS Lambda in 2014 which allows developers to run code without worrying.
It relieves developers and architectures the worry of provisioning, purchasing and managing backend servers. Initially, anyone who wanted to develop a web application had to have hardware to run a server. It takes a lot of time and capital to develop.
Serverless allows developers to purchase backend services where all the server space and infrastructure concerns are overseen by the vendor. It helps you perform common functions like autoscaling in a REST API. So, what are the advantages of serverless computing?
Everyone wants their app to be great. If it becomes a success, will it be able to handle the traffic? Provisioning infrastructure becomes a major concern. Serverless approach is ideal and flexible for scaling applications.
The vendor handles all your functions and runs them separately. This gives you a chance to scale them automatically and endlessly. With serverless, you don’t have to purchase an approximated amount of resources, you can be as flexible as manageable.
Serverless approach saves time and resources. It’s a pay as you go computing meaning you are charged the memory and time allocated to your code. Idle time is not billed. Cost benefits include lack of operating system costs including installation, dependencies, support, maintenance and patching. This saves cost in a huge way. The traffic you have determines what you pay.
The ability of an app to scale depends on network latency, its number of users and the users’ location. We live in a global village and many apps have global audiences. This can create latencies which can demean experiences. Serverless providers have points of presence near every user aiding the apps to perform optimally for everyone.
Decreased time to market
Serverless approach has enabled developers to develop apps in hours and days as opposed to weeks and months. Many new apps depend on third-party APIs. It is event-driven. Architects can run, test and deploy their code without relying on ops to test their code.
Users don’t focus on the infrastructure of the app but its features and experiences. Serverless allows the developers to focus resources on elements that can make the user happy. They don’t invest time and energy managing and operating the framework. Serverless helps solve many issues.
Serverless approach is a great way for consuming the resources of the cloud. FaaS providers focus on their serverless offerings. After releasing AWS Lambda, Amazon has more offerings on the way. This approach can reduce time to market, operational costs and system complexity.
This technology allows businesses to focus on high value and level applications instead of worrying about configuration. FaaS technology on the rise and business is adapting the way they view IT. The development of serverless technology has allowed innovative skills and ideas to shine. It guarantees reliability, performance, scalability, security and cost. You don’t have to worry about service availability.
