Heroku vs Jelastic: What are the differences?

<Write Introduction here>

1. Deployment Approach: Heroku uses a Git-based deployment approach where developers push their code to a Git repository, and Heroku automatically builds and deploys the application. In contrast, Jelastic supports various deployment methods, including Git, FTP, and SSH, providing more flexibility in how developers can deploy their applications.

2. Scalability Options: Heroku offers vertical scalability, allowing users to increase resources like memory and CPU of a single dyno. On the other hand, Jelastic supports horizontal scalability, enabling users to add or remove instances of containers dynamically to handle fluctuations in workload, providing better scalability options for complex applications.

3. Pricing Model: Heroku follows a pay-as-you-go pricing model based on resources consumed, such as dyno hours and add-ons. In contrast, Jelastic offers a container-based pricing model, where users pay for the resources allocated to each container, providing more cost-effective options for predictable workloads or when running multiple applications.

4. Supported Languages and Stacks: Heroku primarily supports popular programming languages and frameworks like Ruby, Python, Node.js, and Java, making it ideal for web developers. In comparison, Jelastic supports a wider range of languages and stacks, including PHP, Java, Ruby, Python, Node.js, .NET, providing more options for diverse application development requirements.

5. Control and Customization: Heroku abstracts much of the underlying infrastructure and platform details, limiting the level of control and customization available to users. In contrast, Jelastic offers more control over the environment, allowing users to tweak platform settings, install custom software, and manage network configurations to meet specific application requirements effectively.

6. High Availability and Failover: Heroku provides high availability with its robust infrastructure and automatic failover mechanisms. Conversely, Jelastic offers advanced high availability features like automatic horizontal scaling and automated disaster recovery for improved resilience and fault tolerance in production environments.

In Summary, Heroku and Jelastic differ in their deployment approach, scalability options, pricing models, supported languages, control and customization levels, and high availability features, catering to different needs of developers based on specific requirements and preferences.
