  • Of late, Serverless computing has been fast gaining momentum. Over the past couple of years, AWS in particular, holding talks at enterprise adoption.

    With the launch of the Lambda serverless computing platform in 2014, AWS has taken the front seat in the revolutionary trendsetting.

    As a result, the current era of modern networking industry is experiencing a massive gallop. The coinage of the “Serverless computing” technology have been flowering from a bud at a fast pace.

    With the traditional methodologies gets a paradigm shift. “Serverless computing”  is a rising star in the cloud computing industry. As a result, the benefits are many.

    In other words, the architecture of Serverless computing is designed to an advantage. Here the code execution is under complete control and managed by a cloud provider. So, the developer’s task is getting easy of developing an application and deploy it on servers.

    Firstly, for the people in the favor, inculcating the serverless computing methodology provide workforce solutions.

    Secondly, for others, being an advancing technology meant to bring revolution, calls the need for convincing on the newer technology.

    Meanwhile, if you are looking for more information for consumption, or if you are at any dilemma about investing in serverless computing, consider the following points below.

    Advanced Crux of Serverless Architecture

    The technology works with RestAPIs. It’s effortless to build the serverless APIs using frameworks. To get it started ss a developer, all you need to do is a develop an application framework, a code to be able to ping the backend, and a library for data processing.

    Subsequently, the most significant benefits you avail is the “pay as you use” model. That is to say; the entire scheme is cost-effective while your deployment is on track. The serverless framework comes handy in the integration of various extensions. You get the opportunity of building a varied range of apps using cognitive intelligence, data analytics, chatbots.

    Edge Execution and Cost-effectiveness

    As the fleet of servers is deployed by the serverless computing platform at the primary location around the globe – your code is being executed at the edge, near to the users. Hence, response time is faster, and you pay for the resources you use.

    You pay only for the run time of the function-the duration and frequency of the code execution. On the contrary, included in the other models of cloud computing, it is mandatory to pay for idle resources also.

    “pay as you use” model

    There are many provider offer functions at the edge and StackPath is one of them. You can get it started from as low as $10 per month which includes 15 million request execution.

    Function As a Service (FaaS)

    The implementation of the technology comes under “Function As a Service (FaaS).”

    Here, the cloud vendor takes the responsibility of starting and stopping a container’s platform. The other activities include checks on infrastructure security, scalability. The other plus point here is, developers can run the code of any application/backend service without provisioning servers.

    If we talk about AWS FaaS, then Lamda handles all the rest functionality after the developers upload the code. Also, it is also possible with the implementation of AWS Lambda, to automatically trigger from any AWS services, web or mobile app.

    Nanoservices

    At the current era, people are choosing to opt for a logical domain. The reason being, the ease of delivering new services in the environment. There is minimal extra coding effort to design a usable application. To the context, comes the significance of a domain called  “Nanoservices.” This microservice is reusable and easily deployable.

    Most importantly, the compatibility of serverless architecture with that of nano-services is incredible. The beauty of the nano services is that each functionality comes with its API endpoint. Also, each endpoint points to one separate function file. As a result, the implementation of one CRUD (Create, Retrieve, Update, Delete) executes.

    Above all, this functionality of the microservice integrates with the business solution through a suite of small services. This clips well with serverless computing. As a result, load balancing and scalability is improved. You no longer have to configure clusters and load balancers for servers manually.

    Event-Based Compute Experience

    When you have a high rate of the function calls, it’s like to worry about infrastructure costs and provisioning of servers. In such situations, profitable facilities from serverless providers like Microsoft Azure, Google Cloud Functions comes to rescue.

    You can trigger the functions based on events like upload image, user’s action, message availability and so on.

    Scalability

    In a traditional context, scalability is cumbersome. You have to execute a horizontal scaling for size and computing power of the node. The vertical scaling is the next in the process to preserve the number of working nodes. A rear and tear of man force.

    However, with serverless, you don’t have to worry about it. Compute platform automatically scale the infrastructure to run the code. You have to just figure out an appropriate trigger for a particular event to take place. With each trigger, the code runs simultaneously.

    Capacity Decisions

    According to research, 30% of the physical servers are in a comatose state. The approximate figure is around 11 million servers worldwide. Indeed, if you opt for a traditional server functionality, chances are you end up among this 30%. The server when sitting idle at the data center demands your investment to get going for further usage. That is to say; you fall at the losing end with this plan.

    Serverless Limitation

    In the other vein, the plan with serverless computing is that vendors are given truncheon here. The companies no longer have to depend on the capacity decision. They take the decision and allow the required capacity at the right opportunity based on the needs of the enterprise — all in all, comparatively a good ROI on investment.

    Conclusion

    In conclusion, developers and investors everywhere are embracing this rising technology. The simplicity in the usage structure makes serverless computing cost effective. As a result, the future is here with serverless computing.

    As a part of the integration procedure, vendors provide the API to upload the function with the URL for the user to access. Placing a lot of trust in them is crucial. Apart from AWS Lamda and Microsoft Azure, there are some other notable market players. The frameworks like Google cloud Functions, IBM OpenWhisk also constitutes the serverless wave.

    Looking at the current transition pattern, a lot of companies have associated with the serverless revolution campaign. To Sum up, you can expect this rising technology to reach the pinnacle of the cloud ecosystem.
