Serverless, like the name suggests, does not mean without any servers. So it is not to be taken literally. In this situation, there are servers but because clouding resource as a whole serves the purpose of a service, the developer does not have to worry about maintenance and scaling. In this model, you only pay for the time you have used making it more cost effective and dependable. This serverless architecture allows the creators to deploy their code in the form of small packages and everything else is managed by the cloud providers. With cloud providers like AWS Lambda, there will be numerous services that they maintain. Startups prefer serverless as they can concentrate on the core development instead of anything else that comes with the code and maintenance.
Serverless has lately become popular and people have realized how much of a better option it is than traditional cloud. For a startup to flourish, the main principles are great independence, cost-effective and flexibility. The biggest challenge that startups face is to start functioning properly before a substantial amount flows in. They also have to accelerate the speed of their functioning and become agile as soon as possible. Also, there is the challenge of creating new products and services and bringing them to the market. But the developer also has to keep the customer happy and be updated about their changing needs instead of being busy with maintenance. Startups have to be scalable in a short period of time and be efficient. A dedicated serverless team helps startups with attaining this goal. An example of the efficiency of working as serverless is Instagram. When the app faced overwhelming traffic, it was difficult for them to manage the back-ends. They shifted to a cloud service and this helped the app immensely and they were able to keep pace with the ever-increasing traffic. Later on, the idea of outsourcing computing power became popular and has helped many applications ever since.
A striking feature of serverless is that it takes only a matter of time to bring the product to the market. In short, it takes very less time. The process of creating an app which usually took months can now be done in weeks or days because of serverless technology. Because of this, apps have now come to depend on third-party APIs for services like authentication, maps etc. With serverless, there is enhanced scalability and even when there is skyrocketing traffic, it will be manageable. This is why serverless is the most sought-after technology. Serverless developers help to save in computing power and human resources. You no longer have to spend on servers. Another reason for the high demand of serverless among startups is that they are very cost effective. When startups start with very less to no capital, their economic burden is very less. For enhanced user satisfaction, the creator has to work on developing the features and customer friendliness of the app. With serverless, they only have to work and spend resources on this and every other maintenance is outsourced to the cloud service provider. It increases the app’s latency and geolocation. Now that apps have users within a large physical
area, there might be latencies that diminish experiences. Serverless provides proximity near every user and enhances the experience. This is why startups should choose serverless if they are looking to succeed.
