Serverless Computing: Its advantages and limitations


Serverless architecture significantly depends on third-party services or on custom codes that runs in ephemeral containers, the best known vendor host is AWS Lambda.

After the inclusion of AWS Lambda in 2014 by Amazon, “serverless” gained a huge repute in the industry. This let the firm witnessing a brisk thrive in terms vendors entering the new market with their own solutions. The gaining popularity of Serverless computing prevailed for long because the businesses that access the technology does not have to rent or provision servers for the back-end code to run.

Serverless enables a developer to set an event to activate and leave the infrastructure needs completely to the cloud providers. The purveyor delivers the right amount of compute, storage and memory. The developer does not need to code or even think about it.

“It may sound quite ideal, but with every new interface, every new technology, there is always something hidden which needed to be sprouted out of the horizon”-says AWS DevOps consulting Expert, Alfonso Valdes. Advantages also come with limitations. Serverless issues tend to represent openings for enterprising entrepreneurs. In the coming years, there would be big opportunities for companies building APIs, tooling, security and monitoring and requires a whole host of tools as serverless is likely to evolve.

Serverless architecture is a way to breaking apart the server side applications into functions that each perform definite task. Severless architecture is a extreme task for developers to execute. The entire application has to be segregated, loosely coupled components that can be operated at any scale.

Serverless purveyors take each of these functions and run them in parallel containers that can be monitored, scaled and regulated separately. It delivers some key benefits and solves some challenging scaling problems that are intrinsic to other software architectures.

The real time filtering of chat comments is a great example of serverless architecture working well. The basic business requirements of most chat applications which often means messages must be filtered, parsed or otherwise policed before delivery to recipients.

The “Serverless” Advantage

Whether you’re building a chat app or have a next PUBG game plan, there are plenty of reasons to go serverless:

  • Serverless approaches allow developers to create and re-create new apps in hours and days instead of weeks and months. Examples abound in new apps that rely on third-party APIs for services like: authentication (OAuth), social (Facebook), maps (Mapbox), artificial intelligence (IBM’s Watson), and more. It has lead to the decrease in the delivery time compared to the rest in the market.
  • Serverless architecture has enhanced the load capacity to optimum.
  • Serverless saves the right amount of money for you in terms of human resources and computing power. And if there is no need for always-on servers, then operational costs plummet.
  • Users don’t care about infrastructure; they only care about features and user-experience. Serverless architecture allows focusing on the elements and resources that keep users satisfied. ClickIT Tech Smart Technologies, a team of AWS migration and DevOps consulting experts helps you in growing a rich interface to manage and execute serverless methods with a real-time experience and enhanced operations.
  • Serverless computing services allows you to work in different programming languages which includes JavaScript, Python, Swift, Node.js etc depending upon the nature of the project. Serverless architecture helps in agile friendly product development. FaaS platforms are capable of letting developers focus on code, and make their product feature-rich through agile build, test and release cycles.
  • Serveless architecture has also helped in improving latency and geo-location. An app’s ability depends upon three major factors: its number of users, user’s location and network latency. With serverless, app providers have point of presence near every user and app performs equally for every geo-location.
  • AWS Lambda, the frontrunners in cloud computing services helps you in provisioning the infrastructural and operational process costs. The providers also keep an eye on its maintenance, security and scalability.

The “Serverless” Drawbacks:

  • The performance issues of serverless computing has restricted itself to be the perfect conventional method to opt for. It requires high latency in computing resources and responding to application requirements. Virtual servers often turns out to be primary options for performance issues.
  • The utilization of a single server resource is difficult when it comes to debugging and monitoring of serverless computing.
  • In serverless architecture, the integration testing techniques are usually tough due the lesser units of integration and the tendency to do the integration being higher.

Undoubtedly, serverless architecture is an innovative approach to deploy as well as write application that enables developers to focus on code.

Amazon web services (AWS Lambda) are leveraged to eliminate the need to set up as well as configure virtual machines or physical servers.

In future, more focus will be towards the unification of FaaS frameworks or APIs can be expected. This will help us in allowing run serverless applications on Amazon cloud servers, even on-premises.
