What Is Serverless Computing?

You may have heard about serverless computing. This type of computing refers to a new innovation that separates the need for software applications and hardware components. The main advantage over traditional computing architectures like traditional server computers is that the client does not need any hardware or software components aside from the Internet connection and a web server. In this new age, every company can benefit from serverless computing.

What is the use of serverless computing? It is the ideal choice for companies that want to reduce costs without affecting their operational efficiency and functionality. Serverless computing is an application platform where a cloud provider runs the server independently for a client and dynamically handles the allocation of resources. The word serverless is also a misnomer, as servers do remain involved in the network configuration process though. However, many of today’s cloud platforms allow users to control and manage their servers independently, without being tied to the external infrastructure.

Some of the key advantages of serverless computing architecture are the scalability to a number of virtual servers provided by the provider, along with a lack of need for large infrastructure investments. Developers can focus more on solving problems rather than expanding their current architecture. For organizations with fewer IT professionals and fewer dollars per employee, it is an ideal choice for deploying infrastructure that requires less total IT supervision.

With no need to maintain or manage servers, companies can focus their time and attention on developing their products and services. Cloud providers typically provide all the necessary tools, including IT tools and management tools. These serverless applications are self-contained and thus require little IT supervision. This enables companies to delegate server maintenance, security, bandwidth, processing power and memory to other team members. In addition to this, there are no restrictions on the size of applications as serverless applications can span across multiple physical machines.

Since serverless computing utilizes already established microservices, there is minimal IT support required. Furthermore, as compared to traditional server deployment procedures, it reduces overall deployment costs since there are no server roles to manage. Devops management tasks are also simplified since these tasks don’t require technical skills. Because everything is contained within the application and applications are modular and extensible, developers can easily add new features to the application in the future.

Reduced server costs can be achieved by eliminating server costs such as power, cooling, network connectivity and software licenses. It can also reduce overall IT costs by alleviating the burden of maintaining and managing large infrastructures. Furthermore, with serverless computing, developers can write code and deploy services independently, greatly simplifying deployment tasks. Developers no longer need to worry about maintaining servers or reboot systems after application launches. In most cases, serverless computing requires less technical skills, which results in reduced vendor lock-in. As a result, customers can utilize their software and continue developing their applications at relatively lower cost.

There are several ways to get started with serverless computing. A developer can choose a platform based on his requirement. Platforms such as IaaS, SaaS and Platform as a Service (PaaS) can deliver features that a developer might need. These types of platforms are supported by many cloud providers such as IBM, Google, Amazon, and Microsoft. Developers can also use webpack to generate web services using HTTP, XML, and JavaScript.

The term “serverless computing” can refer to several technologies. However, the most prominent technology used in serverless environment is Aptana’s Platform as a Service (PaaS) and its direct competitor, Joomla. Both technologies deliver app engines that scale up quickly. Both technologies can deliver highly interactive websites with state-of-the-art components and high speeds. Both technologies are based on open source frameworks.
