Serverless computing has been around in the field of cloud technology and developer’s world for more than a year. Since then, it has emerged as a growing trend, making technology enthusiasts lay emphasis on its execution for developing solutions. However, what are the reasons that made serverless computing accepted as a breakthrough in cloud technology?
The Concept of Serverless Computing
To help developers get away from repetitive time-consuming activities and allow them to focus on other important tasks, a computing code execution model was developed which is known as Serverless Computing. Another name for it is FaaS (Function as a Service) where the cloud vendor is in charge of starting and stopping a function’s container platform, assessing infrastructure security, shrinking maintenance struggles, and developing scalability at low operational costs. The objective was to develop microservice-oriented solutions to break complex applications into small, simple controllable and interchangeable modules.
Are There Servers in ‘Serverless Computing’?
The servers are at the backend, managed by cloud service provider, which means developers do not have to worry about the operation, maintenance or provisioning of these servers and can devote more of their time in creating effective and innovative codes.
Why Companies Should Start Adopting This Revolutionary Tech
The reasons are plenty and allows them take advantage of advance tech for maximum benefits – both monetary as well as productive. The decision-making ones include –
Saves Time. Saves Cost.
The most attractive aspect of this tech is that it is based on a ‘pay as you use’ model, which means you will only pay for the runtime, i.e. for the duration your code is executed and the number of times it’s been triggered. As compared to a cloud computing model where you need to pay for even the ‘idle’ resources, Serverless Computing restricts incurring the cost of unutilized resources.
Benefit of Event-based Computing Environment
Infrastructure costs and setting up servers when the Functions call rate is high is a matter of concern for companies involved in developing solutions. To counter such situations, solutions like Microsoft Azure provide an event-based serverless compute environment to help in faster app development. Eventually, developers will no longer have to rely on the ops to test their code; rather they can run, test and deploy their code quickly without experiencing the fuss of the old-fashioned workflow.
Fully Scalable as per the Amount of Work
When it comes to scalability for your application, Serverless Computing is the answer. With every single trigger, your code will run parallel to it, thereby decreasing your workload and saving time in the process. In simple words, when the code is not running, you do not have to pay anything. You are charged only for every 100ms your code runs and for the number of times the code is triggered.
Serverless Computing with Nanoservices
Nanoservices makes Serverless Computing a new paradigm by allowing developers to work with several architectures which helps to structure serverless computing applications. In other words, Nanoservices are the first architectural pattern, as every functionality has its own API endpoint and its own separate function file.Technically, each API endpoints directs toward one function file that implements one CRUD (Create, Retrieve, Update, Delete) functionality. It works in perfect correlation with micro services, another architecture of serverless computing, and enables auto scaling and load balancing. As a developer, you no longer have to configure clusters and load balancers manually.
No More Worrying about Systems That Run the Code
One of the service models of cloud computing and Serverless Computing is IaaS (Infrastructure as a Service) that allow developers to stop thinking about the number of systems needed at any given point of time, particularly during peak hours, if the systems are working to optimal capacity, if the security measures are intact and so on. Thus, development teams can now focus on the core tasks and do not have to worry about hardware aspects and server reservation contracts.
Serverless Computing is revolutionary because of its simplicity, ease of use, productivity enhancement and cost saving capabilities. Developers are embracing this tech with open hands because they no longer have to write the codes from scratch any more. Technology giants are already bringing in frameworks in Serverless Computing like AWS Lambda, Microsoft Azure, Google Cloud Functions, IBM OpenWhisk and Iron.io. There are more companies across the world delving in this tech and soon it will be at the forefront of the cloud ecosystem.(Source: datafloq.com)
