Heroku Cloud Platform

As the cloud computing landscape becomes more complex and diverse, platforms that simplify and streamline application development are in high demand. Enter Heroku, a cloud platform as a service (PaaS) that emphasizes agility, ease of use, and developer experience. In this article, we’ll explore Heroku’s service offerings and how it compares to other cloud platforms.

What is Heroku?

Heroku, founded in 2007 and later acquired by Salesforce in 2010, is a cloud-based PaaS that supports several programming languages. Heroku’s philosophy revolves around abstracting away infrastructure complexities so developers can focus on what matters most – crafting stellar applications.

Heroku’s Services

Heroku offers a multitude of services aimed at simplifying the application development process, from inception to deployment.

1. Heroku Platform: This service is the backbone of Heroku, providing an environment for developers to run applications, microservices, and APIs. It supports several languages, including Ruby, Java, Node.js, Scala, Clojure, Python, PHP, and Go.
2. Heroku Data Services: Heroku offers managed data services such as Heroku Postgres, Heroku Redis, and Apache Kafka on Heroku. These services provide reliable, scalable, and secure options for managing your app’s data, with automatic backups and failover support.
3. Heroku Developer Tools: Heroku’s developer tools simplify every step of the development process. For example, Heroku CLI allows developers to create, manage, and scale their applications right from the command line. Heroku Git provides version control, and Heroku Flow integrates with GitHub for seamless continuous delivery.
4. Heroku Add-ons: These are third-party cloud services that provide additional functionality to Heroku applications. There are over 150 different add-ons that handle everything from monitoring, security, email and SMS messaging, logging, and more.

Heroku History and Development

Heroku was founded in 2007 by James Lindenbaum, Adam Wiggins, and Orion Henry as a platform to make deployment and configuration of Ruby applications easier and more streamlined. The name “Heroku” is actually a portmanteau of “heroic” and “haiku”, which represents the founders’ dedication to creating a platform that simplifies complex tasks into a short, effective, and elegant solution, much like a traditional Japanese haiku.

Facing the Challenges

The journey was not always smooth, however. Heroku was ahead of its time in many respects and faced an uphill battle in getting developers to adopt it, particularly in its early years.

1. Market Education: In the early days, one of the biggest challenges Heroku faced was educating developers about the benefits of a cloud-based Platform as a Service (PaaS). The concept of PaaS was new, and many developers were accustomed to managing their own infrastructure and environments.
2. Trust and Security: Convincing developers to trust an external provider with their applications was another significant hurdle. They had to convince users that their platform was secure, reliable, and capable of handling varying degrees of traffic and usage.
3. Language Support: Initially, Heroku only supported Ruby. This limited its appeal to a broader audience. They had to work hard to add support for other programming languages, including Node.js, Python, Java, PHP, and Go, among others.

Developer Tools and Environments Pre-Heroku

When Heroku was created, app developers typically used a set of tools and configured their deployment environments manually. Here are some examples of how app deployment was normally done when Heroku was in its infancy.

1. On-Premises Servers: Prior to cloud computing, companies typically hosted their applications on their own on-premises servers. This required significant investments in hardware, as well as continuous maintenance, updates, and security management.
2. Manual Deployment and Configuration: Deploying an application usually involved several manual steps like setting up the server, configuring the environment, installing dependencies, and more. Each of these steps could be time-consuming and prone to error.
3. Dedicated System Administration: In the traditional model, system administrators played a key role in managing servers, databases, networks, and software. With PaaS, much of the system administration is automated or abstracted away.
4. Custom Scripting for Scaling: Before auto-scaling features were common, developers had to write custom scripts to handle increased loads and scale their applications.
5. Multiple Tools for Different Tasks: Developers would often have to use multiple, disparate tools for different tasks such as source control, continuous integration/continuous deployment (CI/CD), and performance monitoring. Heroku provides many of these capabilities within a single platform or easily integrates with external tools.

Turning the Tide

Despite these challenges, Heroku managed to carve out a niche for itself through a variety of strategies.

1. Simplicity and Developer Focus: Heroku’s primary strategy was its emphasis on simplicity and developer experience. By abstracting away the complexities of infrastructure management, Heroku allowed developers to focus on what they do best: building great applications.
2. Early Cloud Adoption: As one of the early players in the PaaS space, Heroku benefitted from the broader trend of businesses moving to the cloud. This trend increased as companies began to see the benefits of outsourcing infrastructure management to focus on their core business.
3. Salesforce Acquisition: Heroku’s acquisition by Salesforce in 2010 was a significant boost, providing additional resources and credibility. This allowed Heroku to expand its services, improve its infrastructure, and reach a broader audience.

Continued Innovation

Over time, Heroku has continued to innovate and add new features and services. These include add-ons for third-party services, extending language support, and providing additional tools for developers, such as Heroku CLI and Heroku Flow.

Heroku Vs. The Competition

When compared to infrastructure-focused services like Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure, Heroku stands out for its simplicity and developer-centric design. However, this simplicity comes at a cost.

1. Ease of Use: Heroku is designed to simplify application deployment. You don’t have to worry about server provisioning, configuration, or management. This contrasts with AWS, GCP, and Azure, where there is a steeper learning curve and more manual setup, but in exchange, you have full control over your infrastructure.
2. Scalability: Heroku can automatically scale web dynos (Linux containers that run your application), making it easy to adjust your app’s resources. However, more granular scalability and performance optimizations are available with IaaS providers like AWS, GCP, or Azure.
3. Pricing: Heroku’s simplicity and convenience come with higher prices, particularly for larger applications or databases. AWS, GCP, and Azure, while initially complex, can often be more cost-effective for larger, more resource-intensive applications due to their range of service offerings and pricing models.
4. Ecosystem Integration: If you’re already in the AWS, Google, or Microsoft ecosystem, their respective cloud platforms provide tighter integration with existing services. However, Heroku’s seamless integration with Salesforce could be a deciding factor if you heavily use Salesforce’s suite of tools.

Heroku Alternatives

Heroku’s functionality overlaps most closely with these cloud products:

• AWS Elastic Beanstalk
• Google Cloud App Engine
• Microsoft Azure App Service

The chart below explains how Heroku compares to these alternative services on the core elements of their respective functionalities, including:

• Ease of Use
• Language Support
• Scalability
• Integration
• Pricing

Heroku’s strengths lie in its simplicity, focus on developer experience, and straightforward deployment process. If you’re a developer or a startup looking for an easy-to-use platform that lets you focus on writing code, Heroku is a strong contender. However, for larger enterprises with complex needs, or if cost and precise control over your infrastructure are critical factors, alternatives like AWS, GCP, or Azure may be more appropriate. As always, your specific needs and circumstances will dictate the best choice of cloud platform.
