Can AWS DAX Help Make Your Application The Next Billion Dollar App?

Every developer understands the importance of cache for the development of an application. However, is AWS DAX (Amazon DynamoDB Accelerator) the best out of them all? Read to know more about it!

AWS DAX is one of the latest technological services from Amazon Web Services that is helping revolutionize the world.

Brief History of Application Development

  • It is the cache solution modern application developers rely on to make technological advances faster by microseconds.
  • But before we dive into what it is and can it help you develop the next billion-dollar app, we would like to reflect on the history of tech advancement.
  • There is no doubt that technology in the 21st century has advanced in leaps and bounds.
  • Until the 1980s, the world was a completely different place with different cultures in different parts of the world.
  • One never had access to their information, and if you wanted to mingle with them, you had to fly to them to know the difference.

However, once the ‘90s rolled around and the internet became a thing, everything suddenly changed and was accessible.

Cloud computing is the next step of this varied revolution, with Amazon Web Services leading the charge.

Out of the hundreds of services they currently offer today, we are focusing on AWS DAX. So let’s start from the beginning and answer, “what is AWS DAX?

What is AWS DAX?

AWS DAX (Amazon DynamoDB Accelerator) is a readily available cache solution that is maintained by Amazon Web Services offered to us by AWS.

It is a revolutionary service as it works at least tenfold faster than any of its nearest competitors.

It provides you speed, precession, and accuracy like never before and performs every arduous task for you, so you as an application developer can solely focus on creating the best app possible.

What is a Cache?

However, before we get ahead of ourselves, we would like to take a second to explain to the uninitiated what a cache is.

In layman’s terms, Cache is the memory recall that an application needs to remember information quickly and adequately.

If you have used Google, when you start typing something on it and it starts to auto-fill solutions for you, it is the prime example of a cache.

Why Do you Need a Cache?

We know now the next question lingering on your mind must be, “why do you even need a cache if you are building an application?

It’s a valid question, and its most straightforward answer is that you need a cache integration in your application so it can become fast and operate at a pleasant speed.

People in 2022 have an attention span shorter than a goldfish. Hence, if your application is slow, they quickly get frustrated and move on to the next app that will provide them with the required information.

No one has time to wait, and cache ensures no one has to as it already has all the information available on a speed dial.

Level of Performance AWS DAX Serve You?

Now let’s return to our original service of AWS DAX. Its speed makes it stand out from the rest and it has become the preferred choice of cache solution for all the leading application developers.

With AWS DAX, you can work 10x faster than with its nearest competitor, as you can use it to complete your tasks in single-digit microseconds, compared to the milliseconds others take.

Benefits of Using AWS DAX

When AWS DAX has already become the leading cache solution globally, they are bound to offer benefits that others cannot match.

Hence, out of the many, the following have been handpicked by us, giving them an edge over their competitors:

1. Lightning Performance

The first and most significant benefit AWS DAX provides you is lightning performance, as they are aggressively fast.

No in-memory cache can even dream of performing the tasks of a cache solution at the speed at which they regularly do.

Through various industry tests and using the best practices, they have time and time again come up with a ten times faster program as they can perform tasks in single-digit microseconds.

2. Provides You The Ability To Scale Your Application To Desired Scope

The second benefit AWS DAX provides application developers is the ability to scale on demand.

Whether you need a three-node DAX cluster or ten nodes, it is readily available to provide you with the performance you need to achieve excellence.

Compromise on the application’s performance and scaling is a big no.

3. Completely Managed Under AWS

Every application developer knows the frustration they go through when they have to worry about software or hardware management tasks on cache solution software.

This isn’t the case with AWS’ DynamoDB, DAX, because the Amazon Web Services team completely manages it.

You just get to use the resources to do your job, and none of the maintenance jobs is your task.

4. User Friendly

When you use a third-party cache solution software to develop your application, writing a custom code is a must for you if you want flawless integration.

However, this worry doesn’t apply to DAX because it is completely compatible with all AWS services.

Hence, by using it you just have to focus on developing your application while it does the heavy lifting of miscellaneous tasks on its own.

5. Protects The Data of Your Application

The final benefit we believe AWS DAX provides you is the unrivaled protection of your data when you use it on your application.
