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Rising cost of outdated software

It becomes more expensive for business to use outdated software every day

Maintenance of an outdated system is exponentially more expensive, and global software upgrades are not so much a matter of desire as an urgent and economically justified need.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

What Are the Different Types of Websites?

There are around 200 million websites, which explains why there are so many variations.

Understanding the different types of sites is essential for choosing one that aligns with your needs and becoming an expert. But, if you’re unfamiliar with this world, it’s difficult knowing the next step. Maybe that’s why you’re here; you want to learn about the different types of websites and need a nudge in the right direction.

Sounds like you? No worries, we’ve got you covered. Here are the different types of websites to consider.

Business Website

One of the top benefits of a website is attracting customers, which is why most businesses run their sites. You’ll notice that this style of site features an explanation of the company’s services, how they stand out, and the basic contact details.

Reputable business sites should be easy to navigate and should share extra information about their team to humanize the brand. There should also be a clear call-to-action where prospects can directly connect with the company or complete a goal, such as joining a mailing list.

Landing Page Website

Another popular option is a landing page website where businesses encourage customers to complete a single action. This is great if you want clients to sign up for a newsletter or join an online raffle. Note, if you’re interested in the latter, it’s important to use raffle web design, so that you stand out from competitors.

An effective landing page should have a call to action in the most obvious place. You can also use this style of the site alongside your current one as you can sponsor ads and easily spread the word.

Ecommerce Website

If you’re in the eCommerce industry, check out common sites when designing a website.

This will give you the inspiration to draw from and show you what is or isn’t working. You can either create an eCommerce site for a single business or display an array of vendors, depending on your company. For instance, larger companies like Walmart would display items from different businesses.

Every eCommerce site should have a search bar and filter, so it’s easier for buyers. There should also be an integrated payment and shipping method to streamline the process for both customers and business owners.

News Website 

You may be familiar with a news website layout as it differs from others on this list. The goal of a news site is to educate readers and keep them up-to-date with current affairs, politics, and even the website. Or, if you’re not passionate about the news, you can use this format to run an online magazine.

As a site owner, you can either produce free content or offer it on a freemium basis. This is where readers can access a limited number of stories every month before hitting a paywall. If you follow the free route, sprinkle ads throughout the site, so that you continuously turn a profit.

Forum Website

Forum enthusiasts building a website should check out popular examples for inspiration, such as Reddit and Quora. These sites let users join groups dedicated to their hobbies and share information with one another. Common characteristics include account personalization and moderators to keep the peace.

The beauty of forum websites is you needn’t splurge on cutting-edge design. Instead, keep it simple and easy to navigate, so that users flock to it.

Blog Website

Like a news website, blog sites update and educate their followers about their daily lives or a specific industry. Each post should be on a single page and filed under a specific tag, so it’s easier for readers to browse your site. And if you’re selling products yourself or via affiliate links, make sure there’s a robust payment gateway to turn a profit.

Personal Website

Many people browse website options and find that it’s pointless because they want to run a personal one. For instance, you may want a site for displaying your journal entries or fan fiction. Or, it could be a place where you can upload your wedding photos or your blog posts.

Because of this, you needn’t worry about integrating payment methods or focusing on a visual-heavy layout. It’s wise to choose a simple design and use a reliable service like WordPress, so you understand the basics.

Portfolio Website

If you’re an artist or freelancer, a portfolio website is essential to your career. You can find a relevant layout where you can display samples of your work and grow your client base. You should also dive into your services and include a call-to-action so that viewers know how to book you.

Membership Website 

Another popular example is a membership website. Businesses or organizations like universities use these for internal purposes, such as a web portal. This lets users access important information and stay up-to-date with the latest news.

Membership sites are great because it’s password encrypted so that only members can log into the website. You can also decide whether to have a free or subscription service, depending on your goals. For instance, if you’ve got how-to videos, ask members to subscribe so that you can capitalize on your content.

The Main Types of Websites

As you’re now familiar with the different types of websites, it’ll be easier to design one to suit your needs.

There are many options to choose from, whether it’s a landing page for your raffle site or a site for your small business. You can also decide whether to develop a portfolio or a membership site to protect valuable data. Which one would you choose?

Purpose of an Industrial Linear Slide and How It Works

Purpose of an Industrial Linear Slide and How It Works

The linear slide market is growing. Experts believe it will grow with a CAGR of 4.60% by the year 2030, totaling USD 3.56 billion.

If you wonder why the linear slide market is so big, it is because of how much value it brings to automated machinery. Automated machinery improves productivity, leads to better-quality products, and can increase sales for manufacturers.

That is because automation performs time-consuming, repetitive tasks efficiently. It even helps eliminate a potentially dangerous situation should human labor need to perform these tasks.

What makes linear slides so valuable for manufacturers today? Keep reading for the full scoop.

What are Linear Slides?

Professionals in the automated machinery industry also refer to linear slides as linear motion bearings or linear guides. Linear slides are types of bearings that are smooth on a single axis, allowing frictionless motion.

Actuators, robots, sensors, machine tools, and other mechanical equipment usually require the components of any three-dimensional axes to move in a straight line. However, when one object contacts another object, there is always friction. How much friction depends on the load that is acting on the surface.

Removing Friction

For movements that have less tool wear, low power draw, and reduced heat generation, you need two key characteristics. This is low friction and high precision.

A linear slide is a single component of linear motion machines. It works along with linear motors, actuated cylinders, power screws, and pinion assemblies.

With automated machinery, linear slides are especially for guiding motion, while other elements of machines are for power transmission.

Linear Bearing Types

Applications that require a component to be highly accurate and move along a straight line use linear bearings. It also works well if the object must return to its origin and repeat this frequently.

Choices of linear bearing types include:

  • Flat ball cage
  • Ball spline
  • Air bearing
  • Ball bushing
  • Guide wheel
  • Cam follower
  • Caged needle
  • Journal bearings
  • Linear hydrostatic bearing
  • Guide wheel
  • Linear motion guide
  • Linear roller
  • Flat roller cage
  • Bearing or rail assembly

Linear bearings have many styles and wide load capacities.

Linear Stages

Automated machinery professionals also call this a translation stage. It is a part of a precise motion system. Linear stages are used to inhibit an object’s motion to a single axis.

Sometimes “linear stages” is a term that people interchange with linear slide, but it is not the same. Technically, a linear slice is a linear motion bearing. This is a component of a linear stage.

Linear Slides – Improving Automation Machinery

Now that you know what a linear slide is and how it is making such a big impact in the manufacturing industry, you can understand why it is a growing market. Business practices and technology are constantly strengthening, and improving the way we live, work, and play.

4 Photoshop Tips for Beginners

4 Photoshop Tips for Beginners

Did you know over 70% of people edit their selfie images?

Now, we don’t know if it is with generic filters or through advanced Photoshop skills, but the fact remains that the need to be able to edit images is real.

Did you also know that over 90% of creative professionals use Photoshop as their editing tool of preference?

Whether you want to edit images for personal or professional reasons, you should read on for the best Photoshop tips on offer.

  1. Take The Shortcuts

Experienced Photoshop users employ a variety of helpful keyboard shortcuts to swiftly and efficiently alter images. Learn shortcuts for the actions you’re more likely to execute regularly rather than navigating dropdown menus and submenus, which can feel more confusing when new Photoshop updates are released.

Even though you can complete all of those tasks manually by navigating the UI, mastering a few straightforward Photoshop keyboard shortcuts will significantly speed up your post-processing workflow.

For many different Photoshop operations, like removing background in Photoshop, Adobe provides a comprehensive list of keyboard shortcuts. As you study, think about printing it off or bookmarking the website.

  1. If It’s Risky, Use A New Layer

In Lightroom, you can undo the changes at any time because they are stored in a separate file.

As long as the file and workspace are set up properly, Photoshop can work in that fashion as well. When you open an image, it will always open as the Background layer. Make a duplicate of the background layer by selecting Layer > New > Layer from Background if you want to preserve the original image.

The new layer will now display a copy of your background layer. You now have the freedom to make as many changes as you like to your background copy while knowing that you can always return to the original if necessary.

  1. Save Your Files The Right Way 

Even the most skilled retouchers occasionally flatten an image’s layers and save it in the incorrect format. When you want to make a small adjustment to your project but can only work with a flattened jpeg, it can be really aggravating.

Save a PSD file of your most challenging editing tasks to prevent future difficulties. You can always refer back to your layers separately in PSD files for additional photo editing and adjusting.

Make sure you have plenty of space on your computer because Photoshop files do take up way more space than flattened PNG or JPG files.

  1. Watch Tutorials 

The best advice for any Photoshop user, irrespective of their skill level, is to stay up to date with updates and changes. There’s always something new to learn with software and always new ways to be creative!

Stay up to date by watching tutorials and reading articles!

Fantastic Photoshop Tips! 

Photoshop Tips can help you on your way to image editing greatness, that’s for sure, but you should make a commitment to continuously try to improve your image editing skills.

There’s so much to learn from other creatives, but keep at it; you’re doing great!
