Cross-Platform App Development in Healthcare

When you are going to create a new web solution from scratch or optimize an existing one, one of the key indicators of top high quality will most likely be a high response rate (to user actions) and SEO-friendliness. 

Unfortunately, client-side rendering, which is done by default in many modern web frameworks and libraries, can become an antagonist for developers pursuing these two goals. In this case, it makes sense to consider the possibility of implementing server-side rendering. Below, we will explain to you what it is, what its features are, with the help of which software tools it can be implemented, and also for which projects it is best suited. 

Definition of Server-Side Rendering

Generally speaking, server-side rendering (SSR), as is probably clear from the name, occurs on the backend side. First, the browser sends a request from the client side to the server, after which the SSR server returns an HTML page with all the necessary meta tags, styles, markup, and other attributes. Then, in the browser, the rendering itself happens, the results of which immediately become visible to the end user.

Why is all this necessary if you can use the default option, client-side rendering (CSR)? – you may ask. In fact, everything is simple: search engine crawlers do not recognize the SEO text contained on the pages (or the page, if it is the only one) of the CSR solution. Thus, if the CEO occupies a significant part of the promotion strategy of your project, you can achieve better results only by implementing SSR. Let us add that projects with sophisticated business logic may “suffer” from CSR in the context of performance since the increased load in the form of several synchronous requests will lead to delays in the interface’s response to user actions. And this is exactly the case where server-side rendering can also become a win-win solution.

Currently, SSR technology is actively used in such world-famous solutions as Airbnb, Upwork, YouTube, Netflix, Uber, etc.

What Are the Benefits of Server-Side Rendering?

Now, based on the above, let's look at the key benefits of SSR.

• SEO and social media friendliness. The server side render approach ensures improved SEO ranking through the correct indexing of pages – now, search robots can recognize SEO text and other attributes important for good ranking. First of all, this is due to the fact that now, search robots do not need to read SSR JavaScript code. As for friendliness for social platforms, it is explained by the ability to display colorful previews when sharing SSR-rendered pages – all due to the correct recognition of meta tags. 
• Better app/website performance. SSR rendering provides a faster initial page load as the JS to HTML conversion is done on the backend. Thus, users see refreshed content faster than with CSR, in particular when it comes to dynamically updated pages. In the long term, this can ensure a reduced bounce rate for websites and web applications. 
• Lower load on the user's device and better user experience (UX). Due to the fact that user requests are now processed on the server side, the user device will experience minimal load. All that remains for it is to interpret the HTML code returned by the server.

What Are the Risks of Server-Side Rendering?

To ensure the objectivity of our review, let's also analyze the disadvantages of server-side rendering.

• Higher TTFB. TTFB or time to the first byte is one of the highest priority indicators of good (or, vice versa, insufficient) performance of web pages. This parameter indicates the time it takes for the browser to receive the first byte of page data processed on the server side. Typically, compared to CSR, the TTFB value is higher because instead of returning a file with links to JS, the server spends some time converting JS to HTML code.
• Limits on the number of requests simultaneously processed on the server side. Due to the increased load on the server, the number of requests processed synchronously will be less than in the case of client-side rendering. Thus, the server throughput will be reduced.
• Need to wait for all the HTML code to load. While the page is loading HTML code under SSR, the user will not be able to perform any new actions on it.

If we add to the above disadvantages a fairly high entry threshold into SSR, as well as an increase in the budget of such projects (due to frequent requests to the server), it becomes clear that this approach is not suitable for everyone.

Server-Side Rendering Frameworks and Tools

As for the server side rendering frameworks and libraries that can be used to process client-side requests on the backend, these include React, Next.js, Nuxt.js, Angular (v7 and newer), and Svelte/Sapper. They use one of the most universal server-side templating languages – JavaScript.

Below we propose to consider server-side rendering React concepts only since React is one of the main tools that we use in web development.

Server-Side Rendering vs Client-Side Rendering

Server-side rendering is not a one-size-fits-all solution since there are situations where its alternative, client-side rendering, is the best choice. In particular, if the content on web pages is updated dynamically – that is, it requires the rendering of some components only (i.e., those with whom the user interacted) while the whole page doesn’t need to be updated, CSR is better suited since part of the content with which the user did not interact will be already loaded.

However, considering that during initial initialization, the content is not displayed until the page is fully loaded into the browser (this can take 2 or 3 seconds, which is critical for a modern consumer of Internet content), when implementing CSR, the site may have poor SEO regardless from the professionalism of SEO specialists (note that this is not a default situation, because with the right approach, lightweight projects with CSR are still ranked well). And this is where the SSR React approach can come to the rescue as usually, React server side components are well-recognized by search crawlers. Thus, by resorting to it, you will be able to ensure enhanced content visibility for search engines.

Server-Side Rendering: SEO vs. Performance

As you can already understand, server-side rendering is capable of providing the best SEO performance for solutions that really need it. In particular, thanks to this approach, search engines will not need to interpret JavaScript. At the same time, if you decide to render in React applying CSR by default, for the React server side rendering implementation, you will have to use additional tools to indicate metadata (for example, React Helmet).

As for performance, in the case of high-load projects, with the server side React rendering, this indicator will be better than with CSR since the SSR website or application will not be limited by the resources of the user device and browser. Also, the user device itself will be less loaded since its only task in the context of updating content will be its output (without rendering).

Conclusion

To sum up, we would like to emphasize that with the correct use of JavaScript frameworks for SSR, you can solve the problem of poor ranking of single-page applications (SPAs) as well as content-heavy websites where SEO and bootstrap performance are critical. On the other hand, CSR is suitable for software with dynamically updated content, that is, content that should change without completely refreshing the page.

However, you should not limit yourself to just these two rendering approaches. In particular, there are also hybrid rendering approaches that combine the best characteristics of SSR and CSR. For example, you can consider the static site generation (SSG) vs SSR couple – perhaps the first option will be the best choice for your project.

These days, Fintech is becoming one of the world's fastest-growing industries. Every year, the number of new Fintech startups increases. In 2024, more than 13,000 such enterprises were recorded in the Americas.

Financial technologies include online banking applications, lending platforms, trading platforms, and robo-advisor apps for investing and budget planning. All these innovations demand top-notch Fintech solutions to serve customers, so aspiring Fintech startups need to find a talented team that can build an advanced product.

Key considerations when hiring

Before hiring a FinTech development company, it’s crucial to ensure the specialists have all the essential hard and soft skills. This way, the Fintech application project will have more chances to succeed. So, to hire reliable developers for your project, you need to understand the essential compliance requirements, which you will need to check. 

What are the must-have competencies of web development companies for Fintech?

• Technical knowledge. The company's developers must be well-versed in all the necessary coding languages, frameworks, technologies, and security norms. 
• Background in your niche. Check if a company has a portfolio of projects related to the financial field. 
• Familiarity with applicable finance legislation. The company must know industry norms such as PCI DSS and GDPR.
• Social skills. Seek a team that is able to ensure transparent communication, flexibility, well-organized teamwork, and attention to detail.

Experience in FinTech

Familiarity with the industry is obligatory for financial services development because the specialists must comprehend the main finance principles. A deep understanding of monetary standards and risk management allows developers to craft solutions that meet the niche requirements. Look for a company that has worked on apps or websites for mobile banking, budget management, cryptocurrency wallets, or other products related to Fintech app development. 

Technical Expertise

First of all, make sure the tech specialists know the necessary programming languages. For instance, frontend development for Fintech may require knowledge of JavaScript, libraries and frameworks such as React.js, adaptive and cross-browser layouts, as well as principles of responsive web design and great user experience. At the same time, Python paired with Node.js may be useful for backend development for Fintech.

Secondly, developers must ensure the product's security. To achieve this, they must understand finance APIs and data encryption protocols. Similarly, implementing secure coding methods and following best practices are critical to providing data security. Additionally, expertise in cloud and blockchain technologies can be vital for the safe and reliable launch and scaling of Fintech products.

Security and Compliance Knowledge 

Fintech solutions must meet the latest regulations and standards for user data security. Since Fintech startups and online banks carry sensitive customer data, they are often victims of cyber attacks. That’s why there are legal regulations aimed at the safety of clients and ensuring secure accounting transactions. So, to get secure Fintech development services, check if a company has relevant experience and understanding of the best practices in data protection along with industry norms such as PCI DSS and GDPR.

Communication and Collaboration

Effective communication is crucial for successful Fintech website development. A simple and streamlined interaction provides quick response, the ability to adjust tasks quickly, and full transparency of their implementation. Also, the tech team members must evolve their problem-solving skills, be adaptable, and demonstrate excellent collaborative skills. The last thing can be reached only by an experienced provider, so you should assess the management style in a company.

Research Potential Partners 

Before hiring a Fintech development company, conduct research on your own. A company must have a website providing all the information about its expertise, portfolio, and contact details. Besides, don’t forget to check customers’ testimonials to determine the quality of the services provided. Likewise, case studies of Fintech projects will best demonstrate a company’s expertise and outcomes achieved. 

Develop a Request for Proposal

When you already have a candidate for possible cooperation, the next step is to write a project proposal. Initially, you need to define the project's goals, target audience, desired functionality, and budget. This process will help your possible contractor fully understand your business demands and provide you with a personalized offer.

Conduct Interviews

While conducting a technical interview, ask detailed questions about the development process to check your possible contractor’s skills. Secondly, the organization's leadership style and structure should be analyzed. Inquire about any cross-functional initiatives the company has worked on.

It’s also important to find out who is on the team. In addition to the usual members of a tech team, such as a technical lead, developers, and QA testers, there should also be an expert who works on UI/UX design for Fintech. And, of course, don’t forget to ask about their previous experience in the niche and evaluate their grasp of your business needs and vision of the product.

Portfolio Review

When selecting a software development company, experience is a key consideration. And the easiest way to assess it is by checking the portfolio. Companies that have been on the market for a while usually have numerous projects. However, you need to pay the strongest attention to those connected to the Fintech industry. Check for mobile banking apps, home loan calculators, or trading tools technologies to make sure their design, usability, and the achieved results are close to your goals and needs. 

Conclusion

Developing a Fintech product is not an easy task. Besides the fact you need to retain customers by providing an outstanding service, you also have to worry about things like regulations and data security. That’s why it’s essential to learn how to recruit decent Fintech development specialists. By following the clues given above, you will be able to find suitable candidates.

Most likely you have used these digital tools at least once – Google Docs, Dropbox, and Azure. They are based on the SaaS model. Apart from this widespread one, there are other variations of cloud application services, such as PaaS and IaaS. You will find out about their differences in this article, so keep on reading it. ‍

IaaS, PaaS, and SaaS: Pillars of Cloud Services at a Glance

The highlighted models – IaaS, PaaS, and SaaS – are aimed at delivering digital tools and services to end users through the cloud on the subscription basis.

According to each aforementioned cloud model, end users don't have to pay for these services and tools one time – instead, as they are owned and supported by a specific vendor, the users are provided with entry credentials as they pay for a subscription. Only a steady web connection is needed to start using such a cloud application. At the same time, entire maintenance efforts in terms of cloud services remain on the provider's side. Even more, users are allowed to optimize their own facilities by offloading apps. Thus, they get more space while specific info is stored remotely on a secured server. 

Let's take a deep look at each of these variations:

• IaaS – stands for Infrastructure as a Service and implies access to demand compute, storage, and networking resources, according to the pay-as-you-go pricing model. In this case, we speak about the IT infrastructure used to arrange the operation of diverse tools and regular processes in the remote, end-user’s office outside the vendor’s premises. 
• SaaS – means Software as a Service and supposes that the cloud-based software vendor deploys it on its computing premises, supports it, and provides users with access to it as a ready-made web service. 
• PaaS – stands for Platform as a Service and consists of providing end users with a ready-to-use cloud platform for developing, testing, and deploying their own applications, from simple cloud services to end-to-end industrial systems.

Let's check these cloud service models in more detail.

IaaS Is about Infrastructure

When the IaaS access option is requested, users get numerous facilities –  servers, storage capacities, as well as network options, among others, –  to leverage them as if those could be available physically within their own premises. Overall, the IaaS meaning lies in ensuring steady connection between the end users and IT facilities; the latter ones are located in remote spots.

SaaS Is about Services

This is the most sought-after offer that supposes using apps that are hosted remotely. Based on individual credentials, end users obtain access to such tools to cope with regular personal or business tasks. In return, they pay a predefined price for a timeframe of leveraging SaaS (usually, this is one year or one month). Thus, SaaS meaning is to guarantee straightforward access to specific software under remote and subscription terms.

PaaS Is about a Platform 

It is a remote, cloud-hosted, platform aiming to produce, leverage, and support the operation of diverse apps. The facility holder owns all types of assets that guarantee steady operation. This is an all-in-one option comprising apps, systems, storage facilities, frameworks, functions, safety arrangements and protocols, backup copies, etc. PaaS meaning lies in forming a remote space where users can create, test, and run applications with specific functionality. For an oblivious reason, the PaaS variation is far cheaper in contrast when a user ensures all similar arrangements independently.

Public vs Private Cloud

But what about public vs private cloud – which of these options does each of the above models provide? A private option is entirely controlled by a single service provider without sharing the facilities with others. A public counterpart is offered to an unlimited number of external subjects who only intend to utilize specific offers. Most of the cloud providers are categorized as ones belonging to the second type.

But are there any intermediary options? Yes, there are hybrid cloud solutions, too, that are created and maintained on the so-called “edge” locations, i.e., thanks to both private and public facilities. 

SaaS vs PaaS vs IaaS: Distinct Features to Know

Each approach from the SaaS vs PaaS vs IaaS trio is associated with distinct peculiarities. We will look at them from the user’s perspective:

Choosing the Right Model for Your Case

When the story comes to making a choice, there are numerous pitfalls to take into account:

Bottom Line 

Leveraging software as a service is an efficient approach. It frees the assets owned by an end user and reduces one's expenses drastically. The single point is to have a clear overview of the project for which you request these external services. Therefore, you have to make a perfect match by saving this info with the comparison of sought-after models.
