Heroku Developer Hiring Guide

If you ask someone, “What was the first cloud platform?” chances are very good that they will respond with a resounding “Google!” Most would be surprised to discover that one of the first cloud platforms was a little-known company called Heroku . This company has been in development since 2007. At first, its platform only supported the Ruby programming language. Since then, Heroku has supported Java, Node.js, Scala, Clojure, Python, PHP, and Go.

By supporting multiple languages, Heroku has all the features a developer needs to build, run, and scale applications in most languages.

But what is Heroku? Simply put, Heroku is a cloud platform that allows developers and businesses to go from “idea to URL,” avoiding common infrastructure headaches. So, if your company is looking for the fastest way to develop and deploy applications at scale, you need to hire Heroku developers .

Why would your company choose Heroku? This is an important question, especially when there are more familiar names available for this task, such as Amazon AWS, Google Cloud Platform and Linode. The highlight of Heroku is that it is a great platform for companies with limited budgets or those who are just starting to take advantage of the opportunities available in the cloud ecosystem. This is especially appropriate given Heroku's simplicity of use.

Heroku's main focus is customer-focused applications. To achieve this, the platform simplifies the development and deployment of these applications. And because Heroku manages all the hardware and services, your company can focus on perfecting this new application.

What is platform as a service?

Understanding what Heroku does means understanding Platform as a Service (PaaS). Essentially, PaaS is a cloud computing model in which a cloud service provider provides the necessary hardware and software (such as operating systems, middleware, and runtimes) via the Internet.

The big advantage of PaaS is that companies don't have to deal with the cost and maintenance of hardware, so they can focus on building their applications and platforms. By removing this barrier to entry, even smaller companies and individual developers can deploy applications at scale.

PaaS is the heart and soul of Heroku, which allows the company to focus “ relentlessly on applications and the developer experience around applications .”

For those who need numbers to understand how well Heroku delivers on this promise of easy development and deployment:

• More than 60 billion requests per day.
• More than 13 million applications created.
• More than 200 complementary services offered.
• More than 2.8 million data stores managed.

Heroku also offers constant threat monitoring, automatic and continuous remediation of operating system vulnerabilities, and 24/7 operations.

Hiring Guide

Why might you need to hire remote Heroku developers ?

If your company continues to grow at accelerated rates, you will eventually have to consider adopting a PaaS solution. When this happens, you'll need developers ready to start creating consumer- and customer-focused applications that can scale to meet growing demands.

What kind of applications can you develop and deploy on Heroku? The sky is the limit. And Heroku enables your developers to work with:

• Command Line Interface
• Continuous delivery
• Databases and data management
• Monitoring and metrics
• Application performance
• Add-ons
• Collaboration
• Security
• Git

Heroku applications run in lightweight Linux containers called dynos, which are preloaded with a prepared application slug (compressed, prepackaged copies of an application that has been optimized for distribution through the dyno manager).

This means that your Heroku Developer will need to have a solid understanding of Linux and how to develop in that environment. These same developers will want to have a solid understanding of databases (like Postgres and MySQL), Redis (in-memory data structure storage), and Git.

Other required skills

To make the most of Heroku, your developers must also have a strong understanding of the following:

• PaaS
• Command Line Interface
• Application frameworks
• APIs
• Cloud technology
• Middleware
• Slugs

Although it is not critical for Heroku jobs, application developers must fully understand the 12-Factor Application Manifesto , which is a design methodology for modern application architecture. Heroku is very much informed by this methodology.
