In the digital era, users have high expectations when it comes to website performance. They want websites to load instantly and respond to their actions in real-time. This has pushed developers to find ways to meet these increasingly high standards. Over the last ten years, numerous JavaScript libraries and frameworks have emerged aiming to enhance website performance and interactivity.

While some of these technologies have fallen by the wayside, others have gained traction and are now used by web developers worldwide. One such technology is React.js, an innovative JavaScript front-end library created by Mark Zuckerberg’s team. Here is why: 

The Key Reasons to Choose React

• React’s documentation is comprehensive, covering all aspects of using this library. 
• React is preferred by several leading global companies, including eBay and Adobe, which prompts regular, thoroughly-tested updates. 
• React.js has a mobile counterpart – React Native. This enables developers to create a single app for iOS and Android simultaneously using only React and JavaScript. This approach can save money and time as you only need to engage React developers instead of two separate native mobile development teams. 
• React is currently very popular, making it easy to find experts to build a website using React. 

Given these strengths and more, increasing numbers of companies are selecting React.js for their web projects. But, is React a universal solution? Can it cater to all the different types of websites, such as portfolios, galleries, media sites, business directories, blogs, etc.? The answer is, “Yes, almost always.” For some, though, React is undeniably the best choice.

Let’s examine common scenarios where you might prefer React over other options.

The Most Common React Use Cases 

#1: You’re Building a New Social Network

If you aspire to create a new social network like Facebook or Instagram, React.js is the perfect tool. Social network users expect their actions, like giving a thumbs up or down, to be reflected instantly.

Traditional methods would necessitate one server request per user action, followed by a complete page reload. This process is time-consuming and slows the website down. React, on the other hand, excels at creating Single Page Applications (SPAs).

The advantage of an SPA is that once the main JavaScript file is loaded from a server to a client, all the action occurs in the browser. There’s no need to re-render every element on a page. React monitors for any changes and updates only the affected page components. This is made possible by the Virtual DOM, a feature beloved by React developers.

#2: You Need a Data Visualization Tool to Monitor Your Business KPIs 

Every business, big or small, generates a significant amount of data related to its operations. Keeping track of all this data can be challenging.

The optimal solution is to compile these figures into a single location and display them visually, like on a dashboard. React is ideally suited for this task as it can handle frequent data updates without needing to reload the entire dashboard every time there’s a change. Key features enabling React developers to achieve this include:

• Virtual DOM. Only elements that have new data are re-rendered, speeding up the update process and allowing real-time changes. 
• Server-side rendering. Without delving too deep into technicalities, React developers can run identical JS code on both the host and in a browser. This eliminates the blank page issue during dashboard loading and operation stages. 

#3: You Need to Quickly Develop a Mobile App That Complements Your Website 

Today, having a mobile app alongside a website is common, especially for eCommerce businesses. Here are some ways to do this:

• Build separate native apps for Android and iOS – a costly and time-intensive option. 
• Create a hybrid app using standard web technologies (HTML, CSS, and JavaScript).
• Develop an app for both iOS and Android using mobile frameworks like React Native. React.js and React Native are akin to elder and younger siblings. The latter utilizes the React.js library, so a React developer familiar with JavaScript can quickly master React Native.
  
  While React Native has its unique features (for example, it doesn’t use HTML), it adheres to the same architectural principles as React.js. Consequently, you can swiftly develop a mobile app that’s virtually identical to an Android or iOS app.

#4: You Want to Sell Products Online

Using React.js library in your online store can significantly enhance the functionality and user experience. This is largely due to its component-based structure, which is akin to individual apartments in a building complex.

The benefits of using React components in your e-commerce platform are threefold:

1. Sustainability: If a single component malfunctions, it doesn’t disrupt the performance of the remaining components. This resilience counteracts a common issue with traditional web platforms where an error in one area halts the entire system’s operation.
2. Reusability: Developers can easily transfer an existing component to another website or application, accelerating the development process. Imagine your site as a modular construction set – you can adjust existing React components to meet specific business requirements.
3. Responsiveness: Components can swiftly respond to changes within their designated scope. For instance, a component containing a form could display distinct notifications to different users based on whether the form was accepted or rejected without necessitating a page reload.

Overall, React components expedite the development of online stores and ensure their efficient, speedy performance. This gives you a significant competitive advantage.

When Should You Consider React.js?

• Consider engaging a React JS consultant if your project involves a complex user interface. Traditional tools may struggle to manage such tasks effectively. React, with its flexible components, enables the creation of any site architecture, regardless of complexity.
• React is also a good choice for highly interactive websites with many dynamic elements – buttons that are enabled or disabled based on user responses, form fields that appear or disappear for individual users, navigation items that highlight or fade, and so on.
• Choose React for projects that involve frequently updated data that needs to be viewed in real-time. Thanks to its virtual DOM and server-side rendering capabilities, users won’t encounter blank pages.
• React is optimal for rapid site assembly, like creating a Minimum Viable Product (MVP) to test a hypothesis. A React development team can achieve this by incorporating ready-made components into an existing site.
• Finally, businesses planning future expansion will benefit from React. Even if they just have a simple, static site currently, React can be used to add new features and increase site complexity and interactivity, enhancing engagement with the target audience as the business grows.

Conclusion

React.js is a powerful tool that offers a myriad of benefits for businesses seeking a robust and efficient solution for their web and mobile application needs. Whether it’s creating highly interactive interfaces, data visualization, rapidly developing mobile apps, building online stores, or planning for future expansion, React.js provides a valuable solution. 

Incorporating the component-based structure, virtual DOM, and server-side rendering capabilities, React.js ensures high performance, reusability, and sustainability of applications.

Navigating the broad array of hosting options available today can be overwhelming. This article aims to guide you in selecting the optimal WordPress hosting for your needs. Keep reading to understand:

• The basic types of hosting
• Factors to consider when picking a provider

Exploring Hosting Options

First, let’s delve into the primary characteristics and distinctions between the fundamental types of hosting on offer.

Free WordPress Hosting

Indeed, it is possible to find WordPress hosting at little to no expense. However, prudent users know that truly free hosting doesn’t exist as server support and maintenance require resources and effort. Consequently, you’ll end up paying for such hosting in alternative ways.

Typically, free hosting is offered by individuals reselling a small portion of their server space. To provide free hosting, these providers might:

• Request you to display a banner ad on your site
• Ask for a text link in your website’s footer
• Restrict your website’s traffic.

Clearly, banners could be irrelevant to your site, negatively impacting your business image. If the server quality is subpar, it may struggle with high traffic, leading to potential downtime. Moreover, free hosting lacks reliability as there’s no guarantee of continued server resource sharing.

We advise assessing your needs and opting for other reasonably priced options. Investing in reliable WordPress hosting ensures peace of mind.

Shared Hosting

As the name implies, shared hosting involves sharing server resources with other websites hosted on the same server. Generally, shared hosting is a cost-effective way to get your site up and running. It’s affordable due to the cost-sharing nature of multiple sites using one server, meaning your website’s performance hinges on the server usage by other sites.

Some providers tout offering unlimited resources (like bandwidth or storage space) in shared hosting. However, the concept of ‘unlimited’ is often misleading. Since multiple sites share server resources, there are inherent user limitations. Your site shouldn’t overload the server. 

Therefore, shared hosting isn’t ideal for websites with significant expansion plans. But, it’s a viable option for launching a landing page or small website.

Managed Hosting

This type of hosting involves assistance or ‘management’ with server resources. Essentially, the hosting company aids with software setup, server optimization, administration, and support. Depending on your chosen provider, you may also receive hardware management, basic security checks, etc.

Managed hosting typically offers specialized solutions for specific needs or software. Consequently, fully managed WordPress hosting is available. Experts will assist with WordPress-specific challenges, provide back-end support, backups, and advice on optimizing your website or plugins for peak performance.

While managed hosting often comes at a higher cost than shared hosting, the increased security and specialized support generally justify the expense.

WordPress VPS Hosting

VPS, or Virtual Private Server hosting, provides you with a virtual machine. This service assigns you a specific section of a physical server computer from the hosting provider. Despite the server being shared among multiple users (similar to shared hosting), you are given more server control and a designated amount of memory.

Unlike shared hosting, where your website’s performance could be impacted by other sites on the same server, your site’s data isn’t affected by the sudden demands of other users’ websites in VPS hosting. Plus, you typically have complete root access to the server, enabling you to tailor your resources to operate certain software.

This hosting option is worth considering for medium-sized businesses, intricate web software, and rapidly growing websites. 

WordPress Dedicated Server Hosting

As suggested by ‘dedicated’, this type of hosting offers you a whole physical server (a dedicated computer) from the hosting provider, exclusively for your website. This means you have total control over resources, including the choice of operating system.

Dedicated hosting is ideal for high-traffic websites or those that require significant computational power for specific applications. The cost for this hosting type starts at $100 per month. If you’re a beginner, dedicated hosting is usually not necessary.

WordPress Hosting Requirements

When setting up a WordPress website, it’s crucial to understand the basic server requirements, which include:

• PHP version 7.4 or higher
• MySQL version 5.6 or higher OR MariaDB version 10.1 or higher
• HTTPS support

As you can see, these requirements are quite concise. Any server supporting PHP and MySQL is suitable for hosting a WordPress site.

Factors to Consider When Selecting WordPress Hosting

Selecting a web hosting provider can be influenced by various factors. Primarily, the technical features offered by these companies should align with your project needs. Therefore, understanding your personal or project requirements is crucial to determine what you anticipate from your website and user interactions. Here are some specific criteria and factors that can impact your hosting provider choice.

Project Scale

If you foresee growth in your website and business needs, it’s wise to opt for a dependable solution from the onset. WordPress hosting solutions can cater to diverse projects or businesses based on their specific requirements.

For instance, an online bookstore and a law firm may both be in search of a hosting provider. The bookstore will require space for multiple product uploads, updates, and secure client information storage. 

In contrast, a law firm’s website might not expand rapidly and could serve as an informational platform detailing the team, services, cases, and contact info.

Websites/Domains and Subdomains Quantity

Understanding the number of websites you wish to host on a single server is essential. Typically, the more sites you host, the higher the cost. Depending on the provider, there may also be restrictions on subdomains. If your project requires subdomains, ensure to verify the  number allowed within your chosen plan.

Storage Space

The amount of storage space is generally limited across various hosting options. Therefore, estimate the volume of data your website will hold and consider future storage expansion needs.

Website Traffic

Your projected website visitor count is significant. Hosting providers typically specify the traffic their plans can accommodate.

Databases

Hosting plans can have limitations on either the number of databases or their size depending on the provider. Even if ‘unlimited database’ is listed as a feature, verify the database requirements.

Security

SSL certificates safeguard websites by encrypting data, ensuring customer information isn’t compromised, forged, or intercepted. Many hosting providers offer free SSL certificates with their plans.

Some providers also include SSH (Secure Shell) for secure user-server communication. This feature is crucial for administrators and web developers as it allows direct, safe access to the hosting account on the server. Enabling SSH also allows for secure file access, management, and transfer via SFTP.

Managed WordPress hosting plans often come with enhanced security features compared to shared hosting.

Staging Environments

Having a staging site or environment to test changes before going live is beneficial. Some hosting providers offer this feature, allowing you to easily transition the site from staging to live.

Caching

In hosting, caching acts as an intermediary between the user and the server. It helps speed up page loading time for visitors by storing copies of requested pages. This reduces server resource consumption. However, it’s important to periodically clean or refresh the cache, especially when website content changes.

Backups

Regular backups enable automatic data recovery if issues arise. Depending on account type and server specifications, backups can occur daily or every 3-7 days. The frequency of backups should align with how often you update your website. Also, consider the timing of backups, with some providers offering nightly backups to avoid slowing down the website during peak usage hours.

Customer Assistance

There may be times when you encounter difficulties setting up your WordPress site or experience server-related issues. When your website goes down, waiting for assistance can be agonizing and could result in potential customer loss. Therefore, it’s comforting to know that your hosting support team is available around the clock to help resolve any problems.

Support can be accessed via various channels: phone calls, emails, tickets, or live chats. Higher-tier plans often include expedited, advanced priority support, delivered by highly skilled agents.

Page Speed’s Impact on SERP Rankings

If generating organic traffic from Google is a priority, then the loading speed of your site is a crucial factor. As early as 2010, Google declared that speed would influence desktop search rankings. By July 2018, this criterion was also extended to mobile searches. Hence, search engines assess the user experience on a site, meaning the quicker a site loads and provides users with their desired information, the higher it’s likely to rank in organic results.

The speed of a webpage can largely depend on its content. Identical hosting resources can yield varying speed outcomes for websites with clean HTML coding compared to those cluttered with numerous plugins or a poorly written theme.

Additional Features

Various hosting services offer bonus features such as a complimentary domain name (typically for one year), bespoke WordPress themes for faster website construction, website builders, and more. To entice businesses, some providers include SEO tools, business email accounts, WooCommerce extensions, Google Ads, and Microsoft Advertising spend match credits in their premium packages.

Cost Considerations

We recommend thoroughly examining the pricing plans after outlining your needs. This way, you’ll understand what each company provides, identify the key criteria, and determine what’s most important to you.

To attract customers, hosting providers often present special introductory prices applicable for the first month or a set period. However, regular prices can  differ significantly from these promotional rates. Therefore, to avoid confusion, we advise verifying:

• The duration of the discounted rates
• The conditions required to qualify for promotional prices (sometimes, a one-time payment covering one or even three years may be necessary)
• The standard prices.

Conclusion

In summary, when choosing a hosting service for your  WordPress website, several crucial factors must be taken into consideration. These include the number of websites and subdomains you plan to host, the storage space required, the projected website traffic, and database needs.  

Security features like SSL certificates and SSH are also important. Additionally, look for offerings such as staging environments, caching, regular backups, and dependable customer assistance. Page speed, which impacts SERP rankings, is another crucial factor, as are any bonus features provided by the hosting service. 

Lastly, thoroughly examine the pricing plans to understand the true cost, taking into account any special introductory prices and their conditions. By considering all these aspects, you’ll be well-equipped to make an informed decision when selecting a hosting service.

Comparing cloud instances and virtual machines
After you install virtualization software on your computer, you can create one or more virtual machines. You can access virtual machines the same way you access other applications on your computer. Your computer is called a host, and a virtual machine is called a guest. You can have more than one guest running on the host. Each guest has its own operating system, which can be the same or different from the host operating system.

From the user’s point of view, the virtual machine runs like an ordinary server. It has settings, configurations, and installed applications. Computing resources, such as central processing units (CPUs), RAM, and storage, look the same as on the physical server. You can also configure and update guest operating systems and their applications as needed without affecting the host operating system.

Hypervisors
A hypervisor is virtualization software that is installed on physical computers. It is a software layer that acts as an intermediary between virtual machines and the underlying hardware or operating system of the host. Hypervisors coordinate access to the physical environment so that multiple virtual machines have access to their own share of physical resources.

For example, if a virtual machine requires computing resources, such as computer processing power, the request is first sent to the hypervisor. The hypervisor then passes the request to the underlying hardware, which performs the task.

Below are two basic types of hypervisors.

Hypervisors of the first type
Type one hypervisors, also called hypervisors without an operating system, run directly on the computer hardware. They have some operating system capabilities and are very efficient because they interact directly with physical resources.

Type 2 hypervisors
Type two hypervisors run as an application on computer hardware with an existing operating system. Use this type of hypervisor when running multiple operating systems on the same computer.

The post How does virtualization work? appeared first on Mans2BE-Rok.

Virtualization makes backing up your entire operating system or server as easy as backing up a group of files. That’s because your virtual OS is just a collection of files.

Suppose a hacker disabled your mail server. If you were running it on a virtual machine, you can simply restore the old version.

Run a different OS.
Let’s say you use Windows every day, but really want to try Linux. Or you have an application that only works with Mac OS. Of course, you can repartition your computer’s hard drive . But the first step to do that should be to create a snapshot of your computer. AKA what virtualization does. Then you have to worry about whether your computer will allow you to shrink it enough.

Having a desktop version of Linux for casual use saves you from having to install PuTTY on Windows . Linux has built-in tools to communicate via a secure shell (SSH). And if your mail or web services are based on Linux, virtualization makes it easy to communicate with the server.

Run ancient applications.
Other interesting things virtualization provides include running applications on older operating systems. Let’s say you have a program that only runs on Windows 8, but you’ve upgraded to Windows 10. No problem, just use virtualization to run Windows 8 on the same computer.

Look at dirty files.
The virtualization software also allows you to create a snapshot of your computer. This means that it saves all of your settings and hard drive contents in another part of your computer. That way, you can make changes to a small part of your computer without making changes to the rest of it. And, more importantly, it means that you can easily undo those changes by going back to an earlier state.

Let’s say you have a file that you really need to read, watch, or listen to, but it’s infected with a virus. If you take a snapshot of your computer before you open the file, you can view/view/listen to the file and then return to the saved version.

Protect your computer from browser stink
Hackers have successfully used all four of the most popular browsers – Chrome, Internet Explorer, Firefox, and Safari.

Protect your computer from browser hacks by running any browser in the sandbox .

From Tor to Firefox , even if your browser or plugin gets hacked, your computer can remain safe with virtualization. Just like a corrupted file, snapshot restores everything to normal, even if a hack occurs.

The post What does virtualization software do? appeared first on Mans2BE-Rok.

An example of virtualization
Consider a company that needs servers to perform three functions:

Secure storage of corporate email;
Running client applications;
Running internal business applications.

Each of these functions has different configuration requirements.

Email applications require large amounts of storage and a Windows operating system.
Client applications require a Linux operating system and high processing power to handle high volumes of website traffic.
Internal business applications require iOS and large amounts of internal memory (RAM).
To meet these requirements, the company installs three different dedicated physical servers for each application.

The company has to make a large initial investment and perform ongoing maintenance and upgrades one machine at a time. In addition, the company cannot optimize its computing power. It pays 100% of the cost of maintaining the servers, but uses only a fraction of their storage and processing power.

Efficient use of hardware
With virtualization, the company creates three digital servers or virtual machines on a single physical server. It defines the operating system requirements for the virtual machines and can use them as physical servers. However, the company now has less hardware and fewer associated costs.

Infrastructure as a Service
A company can go one step further and use cloud instances or virtual machines from cloud computing providers such as AWS. AWS manages all the underlying hardware, and the company can request server resources with different configurations. All applications run on these virtual servers, and users don’t notice any difference. Server management also becomes easier for the company’s IT teams.
