What do you presume is common between Microsoft Silverlight, Adobe Flash, and Java Applets? They were the hottest technology in 2010’s that can be considered as the foundation of web application development.

In the initial days, Netflix was using Silverlight to stream movies and tv series on devices and Windows Phone apps were also developed using Silverlight. In fact, a Chinese railroad company, operating in Liaoning Province, was running its entire operations on Adobe Flash-based software till January 12,2020. This move brought everything to complete standstill, when Adobe deactivated Flash and the railroad officials had to revert to a temporary workaround to resume operations.

Rise of Software Stacks
Due to security concerns and them struggling to keep up as internet technology evolved, they were succeeded by newer technologies such as JavaScript as well as existing technologies such as Python and PHP. Modern web applications are developed using a combination of technology stack commonly known as Software Stacks.

Software stacks mean that different technologies are used for coding the different aspects of an application. Together they work together as the gears in a mechanical system and keep the software operating smoothly.

Some of the popular software stacks used by modern web and app development companies include:

MEAN (MongoDB, Express.js, Angular.js, Node.js)
MERN (MongoDB, Express.js, React.js, Node.js)
MEVN (MongoDB, Express.js, Vue.js, Node.js)
LAMP (Linux, Apache, MySQL, PHP)
Serverless (Google Cloud or Amazon AWS)
Ruby on Rails
Based on the purpose, MEAN, MERN, and LAMP are commonly used technology stacks. The choice of the right technology stack depends heavily on the following factors:

Project requirement
Agility in development
Flexibility and scalability of the dev team
Total development cost
Expertise of the developers
MEAN or MERN
The difference between both technology stacks lies in the front-end framework being used. MEAN stack uses Angular.js while MERN stack relies on React.js to run the code in the browser. MEAN stack was developed by Google in 2009 and is commonly used for building large-scale apps. Paypal, Upwork, and Forbes are major applications built using MEAN stack.

MERN stack was developed by Facebook in 2013 and is useful for building small apps faster. Facebook, Netflix, and Discord are three major applications built on MERN stack.

Before we learn the core differences between MEAN and MERN stack, let’s learn the similarities between both:

MEAN and MERN Similarities
Except for the Front-end framework, both stacks use MongoDB, Express.js, and Node.js. MongoDB is a highly popular document database.that allows applications to store data as JSON (JavaScript Object Notation). Express.js is a popular open-source back-end web application framework based on Node.js that can manage HTTP requests, render basic routing, and create APIs. Node.js is a popular open-source runtime environment choice for web app development by many developers. It supports asynchronous event-driven programming and you get access to many useful community-built open-source tools and frameworks.

The other similarities between each technology stack are:

Open source frameworks
Both support MVC (Model View Controller)
Organize the UI layer components with the help of optimum code
Access a pre-built set of testing tools
Protection from cybersecurity risks and vulnerabilities such Cross-Site Scripting (XSS)
Vast and robust community
MEAN v/s MERN: Core Differences
Now that we have learnt the similarities, it is now time to get into the meat of the topic, i.e., the difference between MEAN and MERN stack. For sake of understanding, we have broken down the differences into smaller chunks.

Learning Curve
When it comes to MEAN stack development, Angular has a steep learning curve as it is comprehensive and employs typescripts and templates. On the other hand, MERN stack development has a comparatively shallower learning curve as React has a richer documentation. MERN has an upper hand at this factor.

Third Party Library Support
Angular has been a popular framework and hence has a robust library that a MEAN stack developer can leverage for different functionalities such as HTTP requests and backend connections. React is a comparatively newer framework and doesn’t have different libraries to fulfil certain functionalities. Moreover, MERN stack developers need to enable additional settings to integrate 3rd party libraries.

Data Flow
Angular has a bidirectional data flow whereas React only supports unidirectional. This means in the MEAN stack, the model status can be altered by changing the UI, while in MERN, the UI can only be changed when the model state is changed. This is not disadvantageous as the unidirectional data flow of React, allows developers to manage large projects efficiently. Similarly, the bidirectional data flow nature of Angular allows practicality required in small projects.

Developer Expertise
Due to lack of documentation in Angular, the knowledge and expertise of the development team is crucial when offering MEAN stack development services. For a reasonably knowledgeable development team, MERN stack is a better alternative.

MVC Architecture
While both technology stacks support MVC architecture, you need an up-to-date architecture when designing an app on a business level. MEAN stack’s UI is independent of the intermediate layer and hence is suitable for enterprise-level projects. MERN, on the other hand, uses JSX for writing and adding HTML code in React, this allows scaling and project structure to the code.

Security
Angular and Node.js are supported by JSON Web Token (JWT). So it secures any unauthorized access to any resource, to encrypt your sensitive data. Moreover, you can implement a cookie-based session by storing the cookie data on the client side. MERN supports authentication methods but it is less secure compared to MEAN stack, as it cannot prevent CSRF (Cross-site Request Forgery) attacks.

Performance
MEAN has a better edge over MERN when it comes to performance. MEAN being a pre-configured framework and using native DOM (Document Object Model), offers slightly better app performance. MERN requires separate configuring and utilizes virtual DOM that increases the rendering time needlessly.

Which to Choose? MEAN or MERN?
MEAN and MERN remain to be state-of-the-art full-stack technology that enables remarkable applications to be developed. Each has excellent characteristics so choosing one would be a tricky issue. Your choice will heavily depend on the benefits each stack brings to the table.

Benefits of MEAN STACK
It is simple to create any type of application.
This stack is compatible with a variety of plugins and widgets. This is useful for development that must be completed within a specific time range.
Due to the availability of plug-ins, the functionality skyrockets.
Because the framework is open source, developers have access to community support.
The built-in tools allow for real-time testing.
Both the back end and the front end are written in the same language. This improves synchronisation and enables applications to reply more quickly.
Benefits of MERN STACK
A single coding script covers both the front end and the back end.
Only JAVA and JSON are required to finish the operation.
The MVC architecture allows for seamless development.
Built-in tools allow for real-time testing.
Runs on an open source community with easily modifiable source code.
Wrapping Up
Selecting the appropriate technology stack will aid your software development efforts. If you’re working on a larger project and need more performance, MEAN stack is the way to go. MERN stack will assist you in developing a variety of web apps ranging in size from tiny to huge, depending on your needs. If you are on the fence about which to choose, our experts can help you.

In the day-to-day activities of a BizTalk administrator, you might come across integrations where FTP sites are used for receiving and transmitting messages. FTP sites are often used for cross-platform integrations. For example, when you have an SAP system on Unix that has to be integrated, via BizTalk Server, with other systems, you might use FTP for receiving and transmitting of messages.

To keep the business process going, it can be of vital importance that the FTP/SFTP sites are online and the messages are being picked up. So, when a BizTalk administrator needs to be constantly aware of whether the FTP/SFTP sites are online and working properly, the administrator needs to monitor the sites and the activities which take place on these sites.

What are the current challenges?
BizTalk Server offers no monitoring capabilities, not for Receive Locations / Send Ports and also not for endpoints like FTP, SFTP and FTPS sites. So, using just the out-of-the-box features of BizTalk Server, a BizTalk administrator will have to manually check whether the FTP sites are online and whether all (appropriate) files are being picked up for further processing.

Manual monitoring
This kind of manual monitoring can be quite cumbersome and time-consuming. The administrator will probably use multiple pieces of software to be able to perform these tasks. Think of for example the BizTalk Administration console to check whether the Receive Locations/Send Ports are up and some FTP client to check whether files are being picked up.

It is obvious that this is not a very efficient scenario, which could easily be automated by setting up monitoring.

Maintaining scripts for monitoring FTP sites
To reduce their workload, we experience that BizTalk administrators are creating their own scripts to monitor FTP sites and all kinds of other resources. Although this kind of script certainly can be of help, we still think this does not fully solve the problem.

To keep the overview, we think that it is easier to use software, like BizTalk360, FTP Monitoring tool, to have everything in one easily accessible place, with good visibility of all the features/capabilities, fine-grained security/auditing, and without the need to maintain custom scripts, etc…[Read more]

Should You Purchase or Lease Your Solar Panel System?
When it comes to harnessing solar energy for your home, the method you choose to acquire your solar panel system—whether through purchase or lease—will have a lasting impact on your finances and system ownership. Let’s examine the key differences between these options.

The Case for Buying Solar Panels
Purchasing solar panels is often the preferred route for homeowners who:

Want to own their solar panel system outright.
Aim to maximize the financial benefits of solar energy.
But what exactly does “maximizing the financial benefits” entail? When you buy solar panels with a lump sum payment, you avoid ongoing monthly payments to a solar provider and instead gain immediate ownership. This can lead to significant long-term savings, as you’re not paying off the system over several years. As an owner, you can directly offset your electric bill with the energy your system generates.

Moreover, buying a solar panel system entitles you to various solar incentives offered by the government. For instance, the federal solar Investment Tax Credit (ITC) allows you to deduct 26% of the cost of installing a solar energy system from your federal taxes for systems installed by December 31, 2022, and 22% for systems installed in 2023 (Energy.gov). This incentive is not available to those who lease their systems, as the leasing company retains ownership and, therefore, the right to the tax credit.

If the upfront cost is a concern, solar loans are available. These loans can provide the benefits of ownership, such as home equity increases and tax incentives, without the need for a large initial investment.

Opting for a Solar Lease or PPA
Key benefits of a solar lease or PPA include:

No responsibility for maintenance
Zero upfront cost
Potential to lock in your electricity rate
If the idea of a $6,000-$7,000 upfront investment is daunting, leasing solar panels or signing a PPA might be more appealing. These options allow you to enjoy solar energy with minimal initial financial commitment. Both leases and PPAs offer the advantage of not having to worry about installation, maintenance, or warranties.

Lease vs. PPA: What’s the Difference?
While leases and PPAs are similar, there’s a critical distinction: a solar lease involves a fixed monthly payment for the use of the solar panels and equipment, whereas a PPA entails paying for the actual energy produced, which can vary month to month. Both can lead to savings, but their availability may differ based on your location.

Making an Informed Decision
Whether you opt to buy, lease, or enter a PPA, transitioning to solar energy is a step toward reducing your carbon footprint and contributing to a more sustainable planet. It’s essential to consider your financial goals, current energy costs, and usage patterns when making your decision.

Interesting statistics that are often overlooked include the rising trend of solar energy adoption. According to the International Energy Agency (IEA), solar PV capacity is expected to set new records for deployment each year after 2022, with annual additions reaching 162 GW by 2025 (IEA). This underscores the growing global shift towards renewable energy sources and the increasing importance of understanding the financial implications of solar investments.
