Designing Scalable Software Products
When you bought your computer and turned it on, more than likely Windows came up. That is of course, unless you’re running a Mac. Regardless, what you saw was the product of scalable software. Scalable software refers to programs that are written with the intent to grow and evolve over the course of time.
Good scalable software designs are generally scalable for audiences of one to hundreds of users. Take for example the Windows OS. Originally, it was clunky. It would work even in VGA 16 color mode. Many of the classic software applications back then still exist today in the same format. But as a whole, the scalable design of windows allowed to progress along with the evolution of hardware and technological improvements.
Now well past its tenth software incarnation, Microsoft and Apple have both demonstrated a clear mastery of scalable software projects. Both now have scalable features including nearly automatic configuration of home networks, support multiple profile accounts, they even are customizable during the software installation phase to be scalable either forwards or backwards of the average users needs.
A good developer can take a page out of the software history book on how to make scalable projects. First, have a broad tier strategy to address not only the current situation and needs, but also leave leg room to grow and be scalable. As your software user base increases, if you were making a simple instant chat client, scalable additions like private rooms and differing worldwide network servers would help facilitate further growth.
Software that isn’t scalable gets left behind as obsolete fairly rapidly. New operating systems come along, and new software comes in to crush the older ancestors. Evidence of what happens when software and protocols are not scalable enough can be seen by taking a look at token ring vs ethernet networking. One is so virtually dead in the modern market; the other one is socketed in the side or back of every laptop and desktop that you find in stores.
After developing a broad scalable strategy, you need to take certain care to modularize code. Highly modularized code allows is more scalable. If all the sudden the current version of *vga becomes obsolete, rather than pouring through an old and highly obfuscated software project, you go straight to the module responsible for graphics handling, update it, and re-release your scalable software project back out into the wind.
Another aspect of scalable software design involves utilizing techniques to add additional throughput. This often means that data has to be stored in unique and efficient ways, instead of easy and inefficient ways. Everything must start off extremely optimized, because in order to be rapidly scalable, you will have to make your software work significantly more efficiently so that it can work harder on hardware equipment that has not had the necessary time to evolve and offset data access and sort times.
Scalable software designs also require a lot of maintenance and upkeep. Additionally, they require adjustments to the existing scale whenever there are large upward or downward surges in user demand. Simply because the software still functions does not allow the developer to abandon the project. Scalable software designs need updates just as frequently as non-scalable projects.
The more demand you can carry and gather for your software, the more money you can make. Through scalable profit that businesses thrive and survive to make more future software releases. By exploring the various techniques and attributes required to make scalable software, developers can attain the lofty goal of any software project should be to maximize usability through deploying valuable features to get as many users using the software as possible.
