The myth of serverless computing and its realm has been the center of debate for years. Honestly, there are several confusions that are running the circles for quite a sometime and today we are going to break it.
Serverless computing has been quite a market itself. This market is expected to reach up to $7.7 billion by 2021 with a 33.3% compound annual growth rate(CAGR). Serverless and function as a service have shown about 75% annual growth and 21% market share.
Though cloud hosting has not been quite new to the scene, recent developments in the cloud-based solutions that allow them to store and manage data quite successfully over a cloud server. This gave the serverless computing a much-needed boost and far more acceptability.
What is Serverless Computing?
Serverless computing is like grilling your barbeque at those public parks, you get the authentic taste without using your own space! Using your own servers for the coding and storage of data needs resources that can cost heavily and doing the same over a cloud server can save all this.
Hence, cloud or serverless computing became quite popular between, users, developers, and even enterprises. With serverless computing, the maintenance overhead of in-house servers is reduced and developers can focus more on building value-added assets.
With the evolutionary technologies over the cloud-based solutions, FaaS-Function as a Service gained more traction, though just a part of the serverless computing, it is used for event-driven applications where logic runs in response to HTTP requests.
The serverless FaaS allows each developer to create a business logic that can be used in an environment provided by the platform. This platform also provides utility-based components with responses to multiple concurrent request calls and strong code isolation.
Myths 101: Every Application is perfect for serverless computing
Not every other application possesses suitability to the serverless computing process. There are several challenges concerned with applications that are data-intensive. Artificial Intelligence and machine learning are now incorporated in the app’s infrastructure and make them flooded with data and to move such large chunks of data to a cloud server can be a huge challenge and this is the sole reason, such applications are not a right fit for serverless computing.
Myth 102: Serverless Computing does not need a server.
Serverless literally does mean the non-server function from the client or user’s end as the server is provided by a cloud vendor. Just like a wireless network does have wires, a serverless computing service does have servers.
Cloud servers are still an existing entity though not in your own backyard. The cloud services vendors provide servers that help store, manage and process data from users and clients over the network.
Myth 103: Developers need special skills for Serverless Computing.
This myth is quite the opposite of what really transpires over the cloud-based solutions. As the data handling, requests handling and presence of a solo code are provided by these serverless computers, developers with low skills can capitalize on the platform. Enterprises or organizations can hire ios developer or developers well-versed in any platform with a nag in serverless computing function, to have the coding procedure aligned with it.
Myth 104: Serverless Computing is not secure.
As the data is stored over a cloud, the data is transferred over the network, making it vulnerable to data breach and data theft. So, many developers and enterprises believe that serverless computing is not safe for their data.
But, the fact that it allows developers to code less and focus on the core product makes it more secure as there is little data vital to an enterprise that is stored to the cloud and user’s data is already regulated through the cloud-vendor security norms.
Myth 105: Serverless computing attracts more cost.
As much as you think of it, serverless computing reduces at least the costs over server, though it may be true that there may be extra costs, but at the end of the day you get much more than you pay for as you will have to just focus on your app and forget about other hassles.
Myth 106: There will be a price surge in Serverless computing.
Many enterprises believe that cloud-vendors may increase their prices for serverless services and this may increase their development costs for an all-time high. But, the facts and figures suggest otherwise. In the event of any such hike, there are several competitors that will pounce on the opportunity.
Besides, in the current scenario, there have been reductions in the market price of such serverless vendor services and no hikes recently.
The best thing about this framework is that all management, capacity planning, resource allocation, and the delivery of those resources happens transparently. This gives the serverless application an extra leverage as it allows the monitoring and controlling of the functions more efficiently.
Serverless architecture used for app development helps the rigid establishment of microservices into the framework. You can develop an application from a single-purpose app to a multi-tasking app using common APIs that are accessed by developers for their respective apps.
The payment towards the services offered by these cloud-vendors is also simplified and cost-effective as you are needed to pay only when your code is run or executed on an event-driven request or response. This payment system allows the development teams and business encouragement to invest more on the product.
