Serverless Applications - Pros and Cons to Help Businesses Decide - Prismetric

In the past few years, especially after Amazon Web Services (AWS) introduced its Lambda platform, serverless architecture became the business realm’s buzzword. The increasing popularity of serverless applications saw market leaders like Netflix, Airbnb, Nike, etc., adopting the serverless architecture to handle their backend functions better. Moreover, serverless architecture’s market size is expected to reach a whopping $9.17 billion by the year 2023.

Global_Serverless_Architecture_Market_2019-2023

Why use serverless computing?
As a business it is best to approach a professional mobile app development company to build apps that are deployed on various servers; nevertheless, businesses should understand that the benefits of the serverless applications lie in the possibility it promises ideal business implementations and not in the hype created by cloud vendors. With the serverless architecture, the developers can easily code arbitrary codes on-demand without worrying about the underlying hardware.

But as is the case with all game-changing trends, many businesses opt for serverless applications just for the sake of being up-to-date with their peers without thinking about the actual need of their business.

The serverless applications work well with stateless use cases, the cases which execute cleanly and give the next operation in a sequence. On the other hand, the serverless architecture is not fit for predictable applications where there is a lot of reading and writing in the backend system.

Another benefit of working with the serverless software architecture is that the third-party service provider will charge based on the total number of requests. As the number of requests increases, the charge is bound to increase, but then it will cost significantly less than a dedicated IT infrastructure.

Defining serverless software architecture
In serverless software architecture, the application logic is implemented in an environment where operating systems, servers, or virtual machines are not visible. Although where the application logic is executed is running on any operating system which uses physical servers. But the difference here is that managing the infrastructure is the soul of the service provider and the mobile app developer focuses only on writing the codes.

There are two different approaches when it comes to serverless applications. They are

Backend as a service (BaaS)
Function as a service (FaaS)

  1. Backend as a service (BaaS)
    The basic required functionality of the growing number of third party services is to provide server-side logic and maintain their internal state. This requirement has led to applications that do not have server-side logic or any application-specific logic. Thus they depend on third-party services for everything.

Moreover, other examples of third-party services are Autho, AWS Cognito (authentication as a service), Amazon Kinesis, Keen IO (analytics as a service), and many more.

  1. Function as a Service (FaaS)
    FaaS is the modern alternative to traditional architecture when the application still requires server-side logic. With Function as a Service, the developer can focus on implementing stateless functions triggered by events and can communicate efficiently with the external world.

FaaS serverless architecture is majorly used with microservices architecture as it renders everything to the organization. AWS Lambda, Google Cloud functions, etc., are some of the examples of FaaS implementation.

Pros of Serverless applications
There are specific ways in which serverless applications can redefine the way business is done in the modern age and has some distinct advantages over the traditional could platforms. Here are a few –

🔹 Highly Scalable
The flexible nature of the serverless architecture makes it ideal for scaling the applications. The serverless application’s benefit is that it allows the vendor to run each of the functions in separate containers, allowing optimizing them automatically and effectively. Moreover, unlike in the traditional cloud, one doesn’t need to purchase a certain number of resources in serverless applications and can be as flexible as possible.

🔹 Cost-Effective
As the organizations don’t need to spend hundreds and thousands of dollars on hardware, they don’t need to pay anything to the engineers to maintain the hardware. The serverless application’s pricing model is execution based as the organization is charged according to the executions they have made.

The company that uses the serverless applications is allotted a specific amount of time, and the pricing of the execution depends on the memory required. Different types of costs like presence detection, access authorization, image processing, etc., associated with a physical or virtual server is completely eliminated with the serverless applications.

🔹 Focuses on user experience
As the companies don’t always think about maintaining the servers, it allows them to focus on more productive things like developing and improving customer service features. A recent survey says that about 56% of the users are either using or planning to use the serverless applications in the coming six months.

Moreover, as the companies would save money with serverless apps as they don’t have to maintain any hardware system, it can be then utilized to enhance the level of customer service and features of the apps.

🔹 Ease of migration
It is easy to get started with serverless applications by porting individual features and operate them as on-demand events. For example, in a CMS, a video plugin requires transcoding video for different formats and bitrates. If the organization wished to do this with a WordPress server, it might not be a good fit as it would require resources dedicated to serving pages rather than encoding the video.

Moreover, the benefits of serverless applications can be used optimally to handle metadata encoding and creation. Similarly, serverless apps can be used in other plugins that are often prone to critical vulnerabilities.

Cons of serverless applications
Despite having some clear benefits, serverless applications are not specific for every single use case. We have listed the top things that an organization should keep in mind while opting for serverless applications.

🔹 Complete dependence on third-party vendor
In the realm of serverless applications, the third-party vendor is the king, and the organizations have no options but to play according to their rules. For example, if an application is set in Lambda, it is not easy to port it into Azure. The same is the case for coding languages. In present times, only Python developers and Node.js developers have the luxury to choose between existing serverless options.

Therefore, if you are planning to consider serverless applications for your next project, make sure that your vendor has everything needed to complete the project.

🔹 Challenges in debugging with traditional tools
It isn’t easy to perform debugging, especially for large enterprise applications that include various individual functions. Serverless applications use traditional tools and thus provide no option to attach a debugger in the public cloud. The organization can either do the debugging process locally or use logging for the same purpose. In addition to this, the DevOps tools in the serverless application do not support the idea of quickly deploying small bits of codes into running applications.

FAQs On a Udemy clone app That You Should Know Before Buying!

learning system based on formalised teaching but with the help of electronic resources is known as E-learning.E-learning, also referred to as online learning or electronic learning, is the acquisition of knowledge which takes place through electronic technologies .

Udemy, which was founded more than a decade ago, has established itself as a global leader in the online teaching industry. People in our digital era rely on technology and devices for nearly everything, including education. When it comes to online learning, or eLearning, which is regarded as a lifesaver– capable of sustaining the educational environment even during the Covid-19 pandemic– it has evolved into a platform bursting with potential, not only for students but also for tutors, educators, and instructors. Furthermore, when compared to traditional educational techniques, the flexibility and customisation given by online tutoring software are unrivalled. As a result, it is gradually becoming an important component of the learning process, which is why eLearning is here to stay– even after the epidemic has passed, it is a huge increase in the number of eLearning applications and websites, and most businesses are choosing for Udemy Clone App instead of starting from scratch.

learn BigBlueButton Technology – Make Efficient Interaction with LMS

How can I get started with your own online tutoring company?

To use the Udemy Clone App script to establish an online tutoring marketplace similar to Udemy, bear the following factors in mind:

  • How to define your target audience?– Before you start developing your Learning Management System, you should think about who you're going to serve, what their background is, what kind of job they want to do, and what their career goals are. These are all things to consider before you begin the development process. As a result, you must be clear about who you are developing your app for.
  • Why have a clear set of goals and objectives in mind?– If you're creating an app for eLearning, you should have a solid strategy and set of goals in mind. You can't simply take a leap of faith and draw conclusions. You must have both long and short term objectives, and you must put them into action.
  • Why create a simple and speedy registration process?– No one wants to spend more than a minute or two on a signup screen, especially if the app is intended for educational reasons. As a result, it's critical that the user registration, login, and signup procedure be simple and quick. It should provide one-tap or social login options so that the AI can read the social account and fill in the data on its own.
  • Why have a visually appealing homepage– "The first impression is the final impression" and "The last impression is the enduring impression" are two prominent expressions. When you initially open the app, the first thing that appears on your screen is the homepage, and if it isn't appealing enough, you will most likely not want to use it. As a result, the user interface must be simple to use and appealing to the eye.
  • Why do we alter and revise– Once you've begun creating the app, you can customise and revise it to meet the needs of your users, thanks to the Udemy Clone Script's high level of customization and a large range of templates and motifs to select from.


If you want to develop a platform with high-quality eLearning features that cater to the needs of a large mass of audience, then opt for ExpertPlus LMS, and contact BSEtec now! Hurry!

Remote Teams and Good Time Management

This year’s global pandemic has forced the fast adjustment for many organizations from in-office normality to a remote working setup at whiplash speed. The rapid adoption of remote working is not easy though—even without the pressure of COVID.

Challenges are abundant for both those with remote working experience and those without. Managers and team leaders are struggling to keep their teams motivated and efficient. Remote teams are often seen as more difficult to manage, but the tips discussed in this article can help you overcome these challenges.

Empower Remote Team Members

Before digging deeper into time and task management, there are actually several basic steps that you need to complete in order to make remote teams effective. The first thing you want to do is making sure that team members can communicate easily and effectively, and that means establishing a way of communicating that everyone is comfortable with.

Most teams turn to Slack, but Slack is not always the best tool for the job. If your team puts emphasis on project management, for instance, using digital Kanban tools with built-in chat feature can be more effective and other communication tools such as Google Mail with Google Chat and Meet integrations are helpful. Microsoft has a similar suite of tools if you’re inclined to that choice of software.

To further empower team members, integrate a good task management platform. There is no way to keep track of everything when team members have to organize their tasks individually. The easier way to establish a baseline for remote working is by using a project or task management tool that turns tasks into blocks waiting to be managed such as Trello, Asana or Basecamp.

Lastly, encourage team members to create a productive environment that works for them. Some startups and corporations are starting to provide team members with aids to help them set up a more comfortable and functional home office. This is the kind of initiative that puts team members in the right mindset for effective remote working.

Overcoming Common Serverless Challenges with Mainframe CICS Programs

By this point most enterprises, including those running on legacy infrastructures, are familiar with the benefits of serverless computing:

  • Greater scalability
  • Faster development
  • More efficient deployment
  • Lower cost

The benefits of agility and cost reduction are especially relevant in the current macroeconomic environment when customer behavior is changing, end-user needs are difficult to predict, and development teams are under pressure to do more with less.

So serverless is a no-brainer, right?

Not exactly. Serverless might be relatively painless for a new generation of cloud-native software companies that grew up in a world of APIs and microservices, but it creates headaches for the many organizations that still rely heavily on legacy infrastructure.

In particular, enterprises running mainframe CICS programs are likely to encounter frustrating stumbling blocks on the path to launching Functions as a Service (FaaS). This population includes global enterprises that depend on CICS applications to effectively manage high-volume transactional processing requirements – particularly in the banking, financial services, and insurance industries.

These organizations stand to achieve time and cost savings through a modern approach to managing legacy infrastructure, as opposed to launching serverless applications on a brittle foundation. Here are three of the biggest obstacles they face and how to overcome them.

Challenge #1

Middleware that introduces complexity, technical debt, and latency. Many organizations looking to integrate CICS applications into a microservices or serverless architecture rely on middleware (e.g., an ESB or SOA) to access data from the underlying applications. This strategy introduces significant runtime performance challenges and creates what one bank’s chief architect referred to as a “lasagna architecture,” making DevOps impossible.
