Over the past half of a decade, there have been considerable shifts in both front-end as well as back-end development. As the clients around the world are becoming more stateful and the development services assisting them to become stateless as well as slimmer. The difficulty of managing tedious services and functions is being eliminated as it allows devops skills to leverage the benefits of serverless technologies. As the project and client go bigger so does the complexity of managing state and the interactions. Frameworks and tooling have started to arise as it allows developers to focus on building product quickly.
If you are wondering why I am bringing this discussion up? Because I think there are lots of potential ways of building new applications. One of the potential ways I have seen over a last couple of years is both the front-end and back-end allows developers to build exciting applications in a minimal span of time. Today’s front-end developers can build robust full-stack applications using zero backend code.
What is serverless computing?
Serverless is a mode of computing that assist developers to write business logic functions and then with the help of cloud let them execute those functions. The deployment provides an environment without virtual machines, visible processes to companies to reduce IT operational cost, be more responsive to customer demand and deploy services faster.
In a simple term humans are consuming water. Water is on constant need, when people are thirsty or for any of their routine activity. So, we are required to do turn on the tap, use water and close the tap. If you want to use again do the same thing again. You may consider it as an abstract explanation of serverless archives.
What’s So Special About Serverless Computing?
- Reduce costs:- Only pay for what you use, may significantly drop the infrastructure cost
- Auto-scale on demand:- Whatsoever your infrastructure support is required, more or less. With serverless, you can have the infrastructure you need.
- Create More Transparency:- Usually, the code is only performed in response to a defined business event. But, increasing the overall reliability and transparency may help handle specific business-event driven execution.
- Eliminate Security Risks:- Instead of focusing on security shifts, access control and perimeter security enable user behaviors, connections, and monitoring of activities.
- Decrease time to market:-
It takes a considerable amount of time to build serverless applications. You are no more required to worry about configuring environments, setting up servers or building a traditional system.
It’s possible for (serviceful) serverless to be the optimal greenfield architecture for 95%+ of all applications without it being the solution for even 5% of all problems actually given to software developers today.

UI Toolkits and Frameworks
On the front-end side, a large number of complexities is increasing because of the rise of SPAs, complex data concerns, increased expectations and multiple device targets have become a lot complex over a past half of decade.
Fortunately, along with the complexity, amazing frameworks and tools come as well. It helps to ease the complexity to focus on creating value. The favorable part is it doesn’t require accessibility and security.
These tools are providing focus to deal with business problems and handle all the technical problems as the evolution of serverless computing. Frameworks like Gatsby, Expo, Ionic, and Meteor are making it possible to build quality applications based on their building blocks.
Serverless and Serviceful
If you have ever built an application in a genuinely serverless sense, then you would be knowing that cost savings and scalability comes as a heaping pile. And if you have experienced that dealing with microservices was a tedious task, divide all the functions into their locations and assemble them through events.
If you are wondering how to leverage the benefits of serverless without managing the difficulty ourselves? Usually, when the technology progresses, it overcomes from the phase of complexity. Serverless itself consist topic configuration, lambda functions and high-level abstractions that may consider themselves product or front-end developers.
It brings a huge amount of serviceful serverless products that may help you leverage the benefits of scalability of serverless, but abstract away meaningful product to solve specific domain problem.
Serverless and Service-full Apps – where Microservices complements Serverless
Serviceful services are set of services in the sense that they do not require to scale seamlessly, but essentially codeless. A few examples include Amazon Cognito/ Autho, Algolia, Contentful, Amazon Lex / Rekognition, Rekognition / Textract, and Cloudinary.
Previously, each of the back-end features like search, API layer, auth require back-end engineering to build securely as well as accurately.
And a front-end programmer can have a look into these services and implement the code with little or no knowledge of back-end at all.
Less Code Less Bugs
As these services are developed and managed by the third party, it requires the most part to write back-end code. Less code means fewer bugs and becomes so easy to maintain.
Less code leads to less complexity. It moves in the discussion from dealing with complexity to removing complexity. The complexity won’t be long anymore as they are no more part of your code base.
The advantages come with increased programmer velocity. In this model trading, you are trading capital expenditure for varied expenses. So, there are better options available instead of paying X amount to the developer to subscribe defined set of features and API about the underlying implementation.
Sophisticated and Secure
These services hold a team of specialized people to maintain and continuously iterate on the given service. It also serves a large number of users as well as customers. It means you will have a team of skilled programmers to build something that could not be done without investing a good amount of time.
It enables programmers and organizations to iterate more quickly to experiment more often than the traditional approaches of building services.
Let’s have a look at the pay per use model serverless providers below
Without a doubt, serverless will gain popularity by simplifying programming environment that makes the cloud much easier to use that’s what attracts people who can and who will use. Previously there was a concern with the scaling of an application into full stack development services, but with the evolution of serverless, I am pretty excited to understand where things will go and take place. In 2019, Serviceful Serverless will be something we will have to see to understand what’s there in coming months and years.
