Why is Serverless Popular? Is it Okay to Go Serverless?
These days, the terms “serverless” and “function as a service” (FaaS) are buzzwords in the software architecture environment.
In the wide, ever-changing world of cloud computing services, serverless and FaaS (function-as-a-service) are two new categories. Both can help developers save money, refocus their time, delegate infrastructure management, and take advantage of cloud technologies.
Although the words FaaS and serverless are often used interchangeably, they are not synonymous.
Serverless is a cloud-native architecture model that allows businesses to create apps faster by removing the need for infrastructure management. The CSP automatically configures, scales, and handles the infrastructure needed to run serverless applications. The concept “serverless computing” is deceptive. It does not imply that you can compute without using a machine. Instead, cloud users can use computing resources without specifically allocating a computer.
FaaS (Function-as-a-Service) is a cloud computing service that permits developers to create, compute, operate, and handle application packages as features without having to manage their own networks.
FaaS is an event-driven execution model that operates in stateless containers and relies on resources from a FaaS provider to handle server-side logic and state.
Why is serverless popular?
Serverless is popular mostly because of the following:
Because of the design of cloud computing, end-user queries are restricted to those that are reasonably easy to code. Software development teams can concentrate on coding instead of hardware maintenance, resulting in improved applications. Developers can make much use of their skill sets by using serverless computing to quickly create applications.
The serverless solution saves both time and money. It’s a pay-as-you-go programming model, which means you only pay for the memory and time your code uses. Idle time is not compensated. The lack of operating system expenses, such as installation, dependencies, service, repair, and patching, are among the cost advantages. This saves a lot of money. What you pay is determined by the amount of traffic you have.
Flexibility and accessibility
It is extremely easy to use serverless computing. Developers can access their data from any smartphone or computer, and they can add additional storage as appropriate. Data can also be backed up on a regular basis. Developers can take comfort in knowing that if anything goes wrong, they can still fall back on the backup version.
The ability to choose serverless is a benefit that can save a lot of time and effort. Instead of depending solely on existing capacity – as in traditional computing – businesses would not be required to purchase additional storage or spend money on unused bandwidth space. Serverless providers have plenty of storage space, which can be distributed in real time.
Is it okay to go serverless?
Serverless computing is still in its infancy and is on its way to being mature. Based on the experience of organizations that have implemented this architecture, there are many third-party add-ons applicable and being built for any customized use. Even though this architecture has a learning curve, if implemented correctly, it will pay off handsomely in the long run.
However, because of its simplicity and cost-effectiveness, companies are gradually adopting serverless computing. Many IT organizations are adopting cloud technologies without consulting their security colleagues. As a consequence, we should expect to see an increase in cyber-attacks in this space in the coming year, with criminals targeting serverless computing environments due to a lack of adequate security.
