In the cloud computing sphere, serverless applications operate through third party services such as AWS. When it comes to hosting a software online, it needs to be managed as well. For managing it, there are some hassles you need to bear. For instance, you will be required to maintain the server for which charges would be applied. 

Moreover, you have to implement the security updates on the server. If you want to save your time and get yourself free from all these tasks, then serverless application is your answer. Continue reading for more information.

1.  Insight About Third-party Services

In order to have a clear picture of what a serverless application is, let’s talk about third-party services and APIs. As a startup or an SME, organization handlers prefer third-party services for outsourcing their projects. Since working with a reputable IT outsourcing company can provide you fully featured automated tools and hosting services to manage the tasks.

Serverless applications managed by third-party services are making organizations free from server infrastructure. With the help of a serverless architecture, you can solely focus on the application functions, whereas code and server software administration will be done by third-party services.

2.  Principles of serverless design

You need to keep in mind a bunch of principles while developing a serverless application from both frontend and backend.

  • Need of a computing service

There is no need to manage the servers yourself. For this purpose, you can use serverless computing service, e.g., Lambda, Azure Functions and Google Cloud Functions etc. to implement the codes. It is much better to use Function as a Service (FaaS) for running your custom codes.  

  •  Stateless functions

     Adhere the single responsibility principle (SRP) to write functions. What is the benefit of this? There would be no problem in testing and debugging the functions. Moreover, you have the leverage of creating a micro service for each function.  

  • Adopt third-party services

Rather than utilizing the custom code you have created, try to go for the services built by third parties. However, don’t forget that every project involves risks and therefore needs appropriate risk management. You need to forecast all potential risks beforehand, including those related to third-party stakeholders, then you will be able to better utilize the resources.  

3.  Pros & Cons of Serverless Computing

      Advantages

  • With serverless computing, you can experience upsurge in developer’s output and decrease in operational expenses. Since, developers would be free of handling servers they would be having the time to concentrate on the other tasks.
  • By incorporating serverless architecture, you could easily adopt DevOps.
  • There are more chances to simplify app development process by including all the components from Back end as Service functions.
  • As discussed earlier, there will be a significant reduction in operational expenditures because you are not dealing with the servers on your own. That’s the benefit of cloud-based computing.

      Disadvantages

  • While you are giving control to the third party for the serverless applications, there could be limitations on how they can utilize their components.  
  • Providing control of your IT stack to someone can also raise the issue of vendor lock in. It refers that you have to fulfill the new vendor’s requirements and it would be costly to switch from one vendor to another.  

4.      Progression of Serverless Systems

Keeping in view the benefits of serverless architecture, it has created a buzz all over. Let’s have a look at the progression of serverless systems. It has three stages.

·  Serverless Stage 1.0

     Characteristics of serverless 1.0 are mentioned below.

Ø  There is no orchestration

Ø  It has functions only

Ø  Implementation time is less

 ·  Serverless Stage 1.5

     Features of serverless 1.5 are given below.

Ø  Functions as well as microservices

Ø  Knative

Ø  Convenient in testing and debugging

Ø  Portable

·  Serverless Stage 2.0

     Characteristics of serverless 2.0 are discussed hereby.

Ø Normal state management
