4 Mantras for Designing Scalable APIs

4 Mantras for Designing Scalable APIs - YWF

The idea of scalability is often offered with a great selling point. For instance, you may be familiar with these tags, “Make your API scalable by tying into our simple API” or “you too can make your service scalable by licensing our endpoint collating system”. These are common sales pitches, but they’re tying into a magic service to make scalability happen, as a web developer, you are likely not being scalable – there’s no silver bullet, and adopting a quick fix doesn’t address underlying architectural deficiencies. Generally, scalable can be defined into 4 big definitions:

  • Extensible: At most basic level, scalable software is extensible. Instead of limiting the functionality, it allows multiple avenues to tie into the underlying services and systems to enable extensions and other services. Amazon’s API Gateway is one of the examples.
  • Built into the Architecture: Scalability can’t be separated from the API itself. So, to make it simple, please build for scalability from the onset. In fact, you can use third party to increase your scalability, especially when they assist a built-to-scale approach.
  • Implies Demand Balancing: As its name, “scale”, you can manage one hundred requests as with one million. However, scalability demands efficient performance, regardless of technique or methodology, both at extremely high traffic and extremely low traffic.
  1. Design for a Repeating Launch Day

Launching a product can be really stressful, you may have prepared for everything, but you simply cannot know the requirements your system might see. For instance when launching a service, what kind of traffic can we expect? Let’s say we’re launching a new social platform that ties into an API to handle 200k calls an hour but the rate has surpassed to several millions of calls. This means that you need to address the foundation of your API as if you are always on the verge launching. Besides, you may need to use load balancer as it can determine between your success and failure. Moreover, having failover paths and secondary functions will produce you to a huge difference towards user experience.

The last important thing is to integrate analytics into your system. By knowing trends developing in real time will help you develop in an agile way and address deficiencies as they arise organically, while predicting further failures down the road.

  1. Anticipate Success

No one will truly know how successful you’re actually going to be. This is because it’s not a simple consideration of traffic, either – traffic might be high even if you’re the second or third most popular choice. Therefore, a provider will plan for the most extreme case possible as he doesn’t know how much traffic they can expect. Another way to frame this would be to anticipate success.

  1. Non-Extensible is a Unitasker

If your application is not extensible, traffic management and scalable mindset is nothing. While extensibility is indeed its own concept, with its own considerations and implications, whether or not a service is extensible can have a direct impact on whether or not it’s scalable. In the end, there is no way that a provider can know literally every possible future use and application of their service while it’s a great practice to develop with scalablity from the onset.

  1. Efficiency is King

You will face so many complexities within your problem, so it is important to know how to simplify your API architecture and thus simplify the resultant solution applied to the problem. In fact, you can drastically reduce the actual resources needed by an application by increasing efficiency.

7 Common On-Site Search Mistakes and How to Fix Them

Common-On-Site-Search-Mistakes-and-How-to-Fix-Them_ywf

Search function is necessary in any website; therefore, you need to be more careful as search function could be damaging your conversion rates. However, when it is well optimized, you can enhance the search function, the usability and enjoyment of your site. As a web developer, you surely want more users enjoy your site, right? Learn how to optimize on-site search and avoid the common mistake that may occur.

It isn’t Visible
First, make sure that your search form isn’t invisible. Creating a search form that is hard to find will frustrate your users. So, ideally your search bar should be located near to the top and left side, the closer, the better. While the search box might not be the first thing that users will see, but you need to be smart to know where you can place it. The right location should be within normal reading patterns.

It isn’t Easy
Anything that places an obstacle between your user and completing their search detracts from its accessibility. So, make sure that any text would disappear once the user starts typing. On the other hand, it is important to increase the accessibility of your search bar include cosmetic changes like color use and text readability. Then, make sure they are sharp and contrasting.

Auto-Suggestions Aren’t Provided
With auto-suggestions, you can speed up the search process significantly for the user, especially if you offer multiple models or versions of a core product. In fact, the less time users must spend typing in their query, the longer they can spend engaging with the content they’re trying to find.

The 404 Isn’t Helpful
You can maximize the usage of 404 pages. It can be useful and beneficial for your users. For instance, you can place links to main directories, offer suggestions for reworking the search query, or direct them to your contact page. The point is to offer solution or answer to your users.

Results Aren’t Straightforward
It is important to create familiar and dressed down search result pages. Hide the bells and whistles of your engine under an advanced search link and, if possible, have the search menu expand without leaving the page. Make sure that the search results landing page is easy to read on first pass, providing legible, plain fonts, and clean composition so that results can be assessed individually.

Filters and Sorting Methods are separated
Since users don’t want to perform any additional work, ensure that sorting options, such as date, popularity, and etc. can be accessed from the same page. Place the options on the top left corner at the start of the search results to increase visibility.

No Search Variation
Always provide your users with variation search results. For example, when a user types “black dress”, you can offer them with alternative search query options and results (such as “black” and “dress”) in separate sections.

By this way, Google can provide closest equivalent, even if you don’t have the product or information they’re looking for. Providing something close, even if not exactly what they searched is more beneficial than an empty results page.

 

The 4 Most Used Programming Languages

Nowadays, software developers are in high demand. This makes good developers are hard to find, yet they have the luxury of choosing from more than one job offer. So, what makes a ‘good developer’? A good developer should at least know some of the following skills. If you wish to become a good web developer, make sure you have mastered below skills.

  1. C#

C# is designed to be relatively easy and straightforward which makes it incredibly popular among developers and employers alike. C# is primarily used to develop web, mobile and enterprise applications while supporting imperative, functional and object-oriented paradigms.

Above all, there are two reasons why C# developers are terribly needed. First, it is because of its flexibility and usability. Second, it is firstly developed by Microsoft to build apps on the Microsoft platform.  So, it surely will fit in most common Microsoft IT infrastructure, which many companies have set in their system.

  1. PHP

PHP is another popular option; it’s an open source, server-side scripting language. In fact, PHP have powered millions of websites across the world, including high-profile sites such as Facebook and Wikipedia. Moreover, PHP is a language that is so popular that is used extensively in WordPress.

Over the years, PHP’s popularity has increased and there are no signs that this demand will slow down. That is why many companies will offer high salary for getting a good PHP talent.

  1. Java

Java is one of the oldest language programs that are favorable among developers. Because it is relatively easy and versatile, Java has become an attractive proposition for corporations and developers. Besides, it has many users, many existing applications and such a vast ecosystem.

Furthermore, Java is a stable language which makes the job market shows sustained hunger for developers in this field.

  1. JavaScript

Another language program that has gained everlasting popularity is JavaScript. It’s a versatile, object-orientated programming language that is built into most major browsers, including Firefox and Safari. Even though, JavaScript has been around for years but it can manage to hold its own against the existence of so many new languages. In fact, many regard it as one of the need –to-know language to help further a career. With so many developers have acquired this language, you need to double your work to stand out from the crowd.
