How do you modernize legacy applications?

Published

on

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Rising cost of outdated software

It becomes more expensive for business to use outdated software every day

Maintenance of an outdated system is exponentially more expensive, and global software upgrades are not so much a matter of desire as an urgent and economically justified need.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

Benefits:

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

Disadvantages:

  • 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.

Benefits

  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.

BLDC Motor Controller Design Principles

BLDC (Brushless DC) motors are widely used in various applications, from consumer electronics and appliances to automotive and industrial systems. To control the speed and direction of BLDC motors, specialized motor controllers are required. At Integra Sources, we specialize in designing custom BLDC motor controllers that meet the unique requirements of our clients’ applications.

What Is a BLDC Motor Controller?

A BLDC motor controller is an electronic device that controls the speed, direction, and torque of a BLDC motor. It consists of a microcontroller or digital signal processor (DSP) that generates the control signals for the motor’s power electronics, including the power transistors or MOSFETs. The BLDC motor controller also includes feedback sensors, such as Hall effect sensors or encoders, to provide feedback on the motor’s speed and position.

Key Design Principles of BLDC Motor Controllers

  1. Sensorless vs. Sensored Control: BLDC motor controllers can be classified into two main types: sensorless and sensored control. Sensorless control relies on the back electromotive force (EMF) of the motor to determine its speed and position, while sensored control uses external sensors, such as Hall effect sensors or encoders, to provide feedback. The choice between sensorless and sensored control depends on factors such as cost, complexity, and performance requirements.
  2. Commutation Techniques: BLDC motors require electronic commutation to control the timing of the motor’s winding currents. There are several commutation techniques used in BLDC motor controllers, including trapezoidal (six-step) commutation and sinusoidal (vector) commutation. Trapezoidal commutation is simpler and more cost-effective but may result in lower efficiency and torque ripple. Sinusoidal commutation provides smoother and more efficient motor operation but requires more complex control algorithms and hardware.
  3. Control Algorithms: The control algorithm used in a BLDC motor controller determines how the motor’s speed and torque are regulated. Common control algorithms include open-loop control, closed-loop speed control, and closed-loop position control. Open-loop control provides basic speed regulation but does not account for variations in load or motor parameters. Closed-loop control algorithms use feedback from sensors to adjust the motor’s speed and position in real time, providing precise control over the motor’s operation.
  4. PWM (Pulse-Width Modulation) Techniques: PWM is used to control the average voltage applied to the motor windings, thereby controlling bldc motors. There are several PWM techniques used in BLDC motor controllers, including six-step commutation PWM, sinusoidal PWM, and space vector modulation (SVM). These techniques vary in complexity and efficiency, with space vector modulation offering the highest level of control and efficiency.
  5. Overcurrent and Overtemperature Protection: BLDC motor controllers must include protection features to prevent damage to the motor and controller in the event of faults or overloads. Overcurrent protection limits the motor’s current to prevent overheating and damage to the motor windings. Overtemperature protection monitors the temperature of the motor and controller and reduces the motor’s power if it exceeds a safe threshold.
