How do you modernize legacy applications?



Changing requirements is the main cause of software “senile diseases”. When the requirements change, the programs no longer handle the assigned tasks correctly. And the need of legacy modernization becomes obvious.

How do you modernize legacy applications

What specific requirements are we talking about?

Changes in legislation, according to which it is necessary to keep records or settlements in a different way.

Load requirements. For example, initially it was assumed that no more than 10 users would use the program at the same time, but later it became necessary for 100, 200, 500 or more people to work.

Fault tolerance requirements. There are modules, the temporary failure of which is not critical, for example, the storage of document templates. But if we are talking about an online store or a banking system, a refusal for an hour is a direct loss, such a situation is unacceptable.

New requirements for user access to the system. For example, there was a need to enter the program via mobile devices, etc.

If the requirements have not changed over the years, the software product can work correctly for a very long time.

New tasks on old rails

Most often, this point follows from the previous one. If a software product has been developed for a long time, but new requirements have appeared from the outside (legislation) or from within (an increase in the number of users, principles of data storage), it can be quite difficult to modify the software for them.

In this case, the obsolescence of software is manifested in the fact that it neither in terms of architecture nor technologically meets new, changed tasks. It is often easier to completely rewrite a program than to try to maintain a legacy version.

Why is this happening? After all, the client invested money in the development and hoped for a long-term use of the product. There can be two reasons:

An incompetent developer who did not take into account the possibility of scaling and supplementing the software package.

Initially short-sighted or incorrectly drafted TOR.

Sometimes it is difficult to explain to the customer that the program is more literate, easier and cheaper to rewrite than to understand the logic and modify the software, which, in fact, ordered a long life.

Rising cost of outdated software

It becomes more expensive for business to use outdated software every day

Maintenance of an outdated system is exponentially more expensive, and global software upgrades are not so much a matter of desire as an urgent and economically justified need.

Lack of software support

There is another case of software obsolescence: when a software module is used that is no longer supported by the developer and, due to an OS update, it stops working. This is a rare case, but it does happen. And if the module is really relevant and necessary, it should be upgraded to be compatible with the new software version.

What does obsolescence lead to?

One of the main goals of a business is to reduce costs. When it comes to software, there are:

  • Development cost.
  • Cost of ownership (how much maintenance and rework costs).
  • License fees, if the software is purchased.

In the event of obsolescence of software, that is, when new tasks appear, the cost of ownership begins to seriously increase. Accordingly, if the requirements do not change, then this does not happen.

But there is another significant problem – the outdated documentation. It often happens that when requirements change and software is revised, no one makes changes to the program documentation. As a result, it does not correspond to reality, and this is also a reason to start modernization.

Software modernization

Frequent occurrence of errors is the first sign of the need for software modernization

So, it is necessary to prepare a technical specification for software modernization if:

  • you need to improve the functionality of the system for new business requirements;
  • outdated development is used, the number of errors has increased;
  • the load on the software has increased significantly;
  • the software does not meet the requirements for performance and fault tolerance;
  • there are significant architectural flaws that negatively affect the flexibility of the system;
  • the software is not scalable enough;
  • there is no support from the system developer;
  • there is no control over the data due to the absence / incompleteness of the documentation for the software used;
  • it became necessary to use more modern forms.

Solutions for the problem of obsolescence of software products

There are several ways to solve the problem of outdated software. Depending on the current business need, you can do the following:

  • buy ready-made software, sold under a license, with further customization for existing business processes;
  • independently upgrade outdated software;
  • to outsource to a team of professional developers.

Let’s consider the advantages and disadvantages of such solutions.

Advantages and disadvantages of boxed software

Boxed software – a ready-made solution from the developer

Boxed software is a quick start, but it can be difficult to customize it for yourself

When a boxed solution is purchased, its modification for the needs of the business and support is shifted to the shoulders of the vendor company.


  • Fast installation.
  • Most often, parametric adjustment of the main functions is assumed on their own.
  • Updated regularly by the developer.


  • The specifics of the business are not taken into account (for customization, you need to negotiate separately with the vendor).
  • The software is not scalable.
  • The impossibility of creating a unique product, that is, such a solution is only suitable for typical business operations, it will not be possible to take into account specific points.

Advantages and disadvantages of boxed software

Advantages and disadvantages of self-upgrading software

If the software has know-how, there are no suitable offers on the market, or a boxed solution is very expensive, it is better to upgrade your own software.

When a company has its own IT department – director, architect and developers – this task can be assigned to them.


  1. The advantages of upgrading software on your own seem undeniable: safety, low cost, quality and control over the process. Is it so?
  2. The costs of creating your own IT department, finding qualified developers are costs. If developer services are not needed all the time, there is no need to maintain an entire IT department. Self-upgrading software can be many times more expensive than hiring an outsourcing company.
  3. Security: no one can get any critical information, because such information is not stored in databases. Another point is its use: the leak itself is terrible only because of the possibility of using information against you. And since critical information is not stored in databases, there is little point in fearing a leak (but this does not mean that you need to forget about security).
  4. Quality: it is not uncommon for staff members to “screw up” and “screw up” only what is “burning” instead of a major software upgrade.
  5. Process control: there is no clear explanation of how outsourcing work control differs from in-house development. Of course, a permanent team is needed to interact with an outsourcer, but the same is required in the second case. Otherwise, control becomes nothing more than a fiction.

What Are The Customized Features Of iTop VPN?



What Are The Customized Features Of iTop VPN?

iTop VPN is a VPN service that offers a variety of features to its users. One of the most notable features is the ability to customize your VPN experience. You can choose which server locations you want to connect to, and you can also choose the level of encryption that you want to use. This means that you can tailor your VPN experience to your specific needs.

Split Tunneling

A split tunneling VPN feature is a great way to keep your identity and location hidden when browsing the web. Using a split tunneling VPN, you can ensure that only traffic from your selected applications will go through the VPN. In contrast, all other traffic will go through your normal internet connection. This can be a great way to improve your privacy and security and your internet speeds.

This allows the administrator to specify which traffic is sent through the VPN and which traffic is sent through the regular Internet connection. This is important because it allows the administrator to ensure that only traffic that needs to be protected by the VPN is sent through the VPN.

IP Configuration

This is important because it allows the administrator to ensure that all traffic passing through the VPN comes from a specific IP address. You can use this IP address to identify the user or device connecting to the VPN. This can be useful if you want to change your IP address or if you want to use a static IP address.

Go to Settings > Network & Internet > IP Configuration to access the IP Configuration feature. You can view and change your IP address, gateway, and DNS settings from here.

The IP address is the most important setting here, as it determines where your device can connect to the internet. If you want to use a static IP address, you will need to enter it here. Otherwise, you can leave the IP address as “automatic,” and your device will automatically receive an IP address from your router.

The gateway is the next important setting. This is your router’s IP address and is used to route traffic between your device and the internet. If you’re unsure what your gateway IP address is, you can find it in your router’s documentation. The DNS settings are used to resolve domain names into IP addresses.

Launch on Startup

When you enable the Launch on Startup VPN feature, your computer will automatically connect to the VPN whenever it starts up. This is a convenient way to ensure you’re always protected when using public Wi-Fi or other untrusted networks. You can verify that the VPN is connected by checking the VPN icon in the system tray. If the VPN is not connected, you can manually connect by opening the VPN settings window and clicking the “Connect” button.

To enable the Launch on Startup VPN feature, open the VPN settings window and check the “Launch on Startup” box. You can find the VPN settings window in the Windows Control Panel or by right-clicking the VPN icon in the system tray and selecting “Settings.”


This post has guided you about iTop VPN. Moreover, if you have a smart tv and want access to the apps unavailable in your country, you can use VPN Smart TV. This VPN will be useful for smart tv users who like to watch content on TV.

How technology is changing the lives of people with disabilities, and improving accessibility and independence?



How technology is changing the lives of people with disabilities, and improving accessibility and independence?

Technology has made many significant changes in the lives of people with disabilities, providing greater accessibility and independence. With advancements in technology, people with disabilities are now able to live fuller, more inclusive lives. In Australia, the National Disability Insurance Scheme (NDIS) provider Sydney has been instrumental in supporting people with disabilities in accessing the latest technological solutions.

Assistive Technology

Assistive technology is one of the most significant advancements that has changed the lives of people with disabilities. These technologies are designed to help individuals with disabilities perform tasks that would otherwise be impossible or difficult. From mobility aids to communication devices, assistive technology has provided new avenues for people with disabilities to live independently.

Mobility Aids

Mobility aids, such as wheelchairs and mobility scooters, have greatly improved the quality of life for people with disabilities. These devices are designed to provide individuals with increased mobility, allowing them to move around freely and independently. They have been developed with features such as shock absorbers and ergonomic designs, which offer better comfort, stability, and ease of use.

Communication Devices

Communication is vital, and assistive technology has made it possible for people with disabilities to communicate effectively. Communication devices, such as speech recognition software and eye-gaze technology, have revolutionized the way people with disabilities communicate. For individuals who are unable to speak, speech recognition software can translate their speech into text. Eye-gaze technology, on the other hand, allows individuals to use their eyes to control a computer or communication device.

Smart Homes

Smart home technology has also been transformative in the lives of people with disabilities. Smart home devices, such as voice-activated assistants, can control appliances, lighting, and temperature, allowing people with disabilities to manage their homes independently. This technology has been particularly useful for individuals with mobility impairments, as they can use their voice to control devices in their homes.

Accessible Transportation

Transportation can be a significant barrier for people with disabilities, limiting their ability to access education, employment, and social activities. However, advancements in technology have led to more accessible transportation options for people with disabilities. For example, ride-sharing apps have introduced wheelchair-accessible vehicles, allowing individuals with mobility impairments to travel more freely.

Social Inclusion

Technology has also played a significant role in improving social inclusion for people with disabilities. Social media platforms, such as Facebook and Twitter, have made it easier for people with disabilities to connect with others who share similar experiences. These platforms have also helped to raise awareness and understanding about disability issues, leading to greater acceptance and inclusion.

Online Education

Online education has also been transformative for people with disabilities. Many individuals with disabilities face barriers to traditional classroom settings, but online education provides an accessible and flexible alternative. With online education, individuals can learn at their own pace and on their own schedule, allowing them to tailor their education to their specific needs.

The Role of NDIS Provider

The NDIS provider Sydney has played a significant role in supporting people with disabilities in accessing the latest technological solutions. The NDIS provides funding for assistive technology, such as mobility aids and communication devices, to eligible participants. This funding has enabled individuals with disabilities to access the latest technology, improving their quality of life and independence.

The NDIS provider has also supported the development of new technologies and solutions for people with disabilities. They have worked with technology companies and other stakeholders to identify areas where technology can be used to support individuals with disabilities.

In summary, technology has transformed the lives of people with disabilities, providing greater accessibility, independence, and inclusion. Assistive technology, smart homes, accessible transportation, social media, online education, and other advancements have made it possible for people with disabilities to live fuller, more inclusive lives. The NDIS provider has been instrumental in supporting individuals with disabilities in accessing the latest technological solutions and promoting the development of new technologies. As technology continues to evolve, we can expect even more significant advancements in the field of disability support.
