Heroku vs AWS

Amazon Web Services or Heroku – Which is Best for Your Business?

You have a great idea for a new piece of software – may be a mobile app or some type of internal tool that will improve your business processes. And you want to deploy that app or program to the cloud. But you’ve got a ton of questions. What’s the best approach to managing infrastructure? And how will my company handle cloud security, monitoring, and networking issues? AWS vs Heroku?

If you are already an AWS user and you either have an in-house DevOps team or if you have contracted out with developers who know you and have met your AWS cloud needs well, then you will go to these experts with your new idea.

But then, someone mentions Heroku to you as a simpler method of development and deployment. You have no knowledge of or experience with Heroku, but maybe it’s time to give it further thought?  So, let’s do just that.

What follows is an overview of how AWS and Heroku stack against one another, what each does best so that you can make an informed decision about whether to opt for AWS or Heroku.

What is Heroku – a Basic Product Overview 

What is Heroku

Source: SlideShare

First and foremost, Heroku is a PaaS solution, sitting atop AWS. In short, it’s a handy cloud app development and deployment service.

As the chart above illustrates, the key element of Heroku is Dynos – proprietary lightweight Linux containers where all app processes run. You are charged you based on how many dynos and the size of the dynos you need. Obviously, the larger the app, the more dynos types you’ll need to use.  You can choose among:

  • Web Dynos: for running web processes.
  • Worker Dynos: any types of processes you assign (e.g. background jobs).
  • One-off Dynos: for running one-off tasks, (e.g. database migrations).

While Heroku’s primary offering is for apps, you can also use Heroku website hosting to gen an Angular.js website on the Internet, for instance.

How Does Heroku Work?

Heroku makes the app development and deployment processes much for efficient. Once your developers are done with the app and send it off to the Heroku cloud, the tool does the rest. It automatically configures the infrastructure and resources provisioning on AWS (where the app is deployed).

An additional perk of Heroku is that developers can build their apps in any language they choose and select from a number of Heroku add-ons (some free, some fee-based) to speed up the development. The simplicity and the time-savings are big pluses.

To sum up, for now, anything built on Heroku is actually deployed to AWS, but still “run” by Heroku.  The question, then, is why use Heroku when a website, apps, and full infrastructure and management can be done through AWS?

The short answer probably lies in simplicity vs. complexity, but there is more to AWS vs Heroku than that.

The Main Differences Between AWS and Heroku 

AWS is an IaaS solution. It’s a much robust, albeit complex offering that serves as a ‘launchpad’ for Heroku.
Thus, it’s not fully accurate to juxtapose AWS (an IaaS offering) vs Heroku (a PaaS product) as that may seem that we are comparing apples to oranges.

What is more reasonable to discuss is the difference between Elastic Beanstalk and EC2 from Amazon and Heroku. Here’s a quick refresher on these two AWS services:

  • AWS Elastic Beanstalk is the company’s proprietary web app deployment service. Similarly to Heroku, it automates your deployments and let’s auto-scale applications.
  • Amazon Elastic Compute Cloud (Amazon EC2) is the flagship cloud-computing platform that lets anyone develop, host, deploy and run their applications on AWS.

Developers who are not familiar with Elastic Beanstalk, and who have only used EC2, have questions about the difference between EC2 and Beanstalk. Here are the answers:

  • EC2 is part of AWS IaaS. Beanstalk is a PaaS platform that enables developers to deploy apps on the cloud and then connect those apps with other AWS services, as they wish.
  • Beanstalk does bring together other AWS services like EC2.
  • While Beanstalk has great default settings, developers can manually manipulate management, such as bypassing, overwriting, and/or adjusting to meet customization needs and requirements.
  • Updates and patches occur automatically.

Now in this context, let’s compare the two offerings.

Pros of Heroku

Heroku is a far less complex tool than AWS Elastic Compute (EC2). Here’s why:

  • This platform equips developers with a fully ready environment and app servers.
  • Heroku seamlessly integrates with existing development tools and a pre-existing operating system
  • Infrastructure management isn’t necessarily the way it is with AWS EC2. Businesses need to choose a subscription plan, with the option to change that plan as needed.
  • Management occurs through a CLI on the simple dashboard.
  • Heroku seems like a great solution for startups and MVP’s until enough feedback is garnered to develop the full app.
  • Users do not have to be concerned about infrastructure, because it is built into the software itself.
  • There are quite a few supportive tools

Pros of AWS

Admittedly, AWS solutions are more complex and require more orchestration and maintenance than Heroku. So, who uses AWS and why? In general, it is the better solutions when an organization has a DevOps team, either in-house or contracted out, that can handle the more complex management functions.

  • When you compare AWS Elastic Beanstalk vs Heroku, the app deployment process is as easy.
  • AWS EC2 is a better choice for high-load applications, requiring a lot of computer power.
  • Many functions are automated (e.g. scaling, configuration, etc.)
  • Fast deployments are a big plus, and capacity can easily be added or removed.
  • AWS offers hybrid solutions
  • It is a better solution for post-startup businesses, because of the sheer amount of services and functions that are available

Cons of Heroku

  • Sometimes, users report that their dynos cannot be reached, and that creates problems.
  • Latency (wait time) can be longer than you can afford.
  • Network performance can be lagging.
  • If you want to buy more dynos or dynos workers, the price is $35 per month. It can be pretty pricey for large apps with a lot of traffic.
  • Thus, Heroku is not ideal for complex projects requiring a lot of cloud resources.

Cons of AWS

  • There can be unreliable deployment, and no error descriptions may be provided
  • Deployments are not as simple as in Heroku and can take a while, even in the case with simple instances.
  • Deploying several app instances at once will require an experienced team.
  • Users must take charge of many management functions themselves, although AWS is continually automating many of these.

In short, AWS requires much more tech expertise; yet it offers far more in the way of functions than Heroku.

So, What’s the Verdict – Heroku vs AWS?

The short answer is, it depends. In looking at who uses Amazon Web Services (AWS), it can be said that organizations of all sizes have found what they need due to the sheer volume of choice. AWS has a mature ecosystem of services, tools, and apps for businesses to use.
However, other than the Beanstalk platform, the use of AWS can be complex and requires an expert DevOps team, either in-house or contracted. In comparison, Heroku is less ‘intimidating’ and is a great one-function product.

It does the job of streamlining app deployments and it does it well. For startups and for those who plan to dispatch smaller apps to the cloud without lots of technical expertise, Heroku can be a good option. The choice between these two fully depends on what your organizational needs are right now!
