CloudFoundry vs. Heroku Platform

It's well suited if:

• The organization has large number of applications that needs to be deployed frequently.
• The organization is tied to the DevOps mindset.
• The organization has programs in different languages.
• The applications does not need EJB's support that servers like web logic provide.

It's less suited if:

• The applications needs security configuration within the same CloudFoundry instance.
• The organization, for whatever reason does not want developers to manage the instances.

Heroku is very well-suited to early stage and/or rapidly changing projects. It is great for getting moving quickly or changing direction quickly. In scenarios where there is already scale or well-defined requirements, it may be preferable to set things up directly on AWS or another cloud provider to avoid the additional costs of Heroku as the middleman.

• Support for Orgs and Spaces that allow for managing users and deployables within a large organization.
• Easy deployment, deploying code is as simple as executing single line from CLI, thanks to build-packs.
• Solid and rich CLI, that allows for various operations on the instance.
• Isolated Virtual Machines called Droplets, that provide clean run time environment for the code. This used to be a problem with Weblogic and other application servers, where multiple applications are run on the same cluster and they share resources.
• SSH capability for the droplet (isolated VM's are called droplets), that allows for real time viewing of the App code while the application is running.
• Support for multiple languages, thanks to build-packs.
• Support for horizontal scaling, scaling an instance horizontally is a breeze.
• Support for configuring environment variable using the service bindings.
• Supports memory and disk space limit allocation for individual applications.
• Supports API's as well as workers (processes without endpoints)
• Supports blue-green deployment with minimal down time

Incentivized

• Amazingly clear and straightforward documentation (versus the quagmire of AWS docs).
• Deploy your entire site in one command.
• Setting up asynchronous job processing for long running operations (e.g. sending emails, making external API calls).
• A wonderful portfolio of tightly-integrated add-ons in their marketplace.

Incentivized

• Does not support stateful containers and that would be a nice to have.
• Supports showing logs, but does not persist the logs anywhere. This makes relying on Cloud Foundry's logs very unreliable. The logs have to be persisted using other third party tools like Elk and Kibana.

Incentivized

• Could be less expensive, although you get what you pay for
• Sleeping apps can be an annoyance: Heroku automatically puts your apps in sleep mode and they have to spin back up after periods of inactivity. Much of this can be solved but it requires working around the built-in functionality. I understand why they do it but it's an area that could be improved.
• Restrictions to server access means you can't customize as much as you could if you owned the server. But again, this is also a benefit because it's about convention over configuration. So you can't configure as much, but then, you typically don't have to.

Heroku is a critical and core part of our infrastructure that is serving our customers well. We are very satisfied with the cost of our solution. While it would be difficult to move away from Heroku, we have no plans to do so. We have had no major issues with it and it is a pleasure to use. Other products on the market might offer comparable functionality, but until we expose a need that Heroku cannot satisfy, we'll stay the course.

If you have basic backend and Git knowledge, deploying to Heroku is a breeze. It now supports many types of backends, including hybrid backends (ex: nginx + application server) through its build pack system. The dashboard is easy to use, and the CLI tools are well designed. Accessing the add-ons is also easy. It uses an SSO-type system so you don't have to re-sign in to view the add-on dashboards.

Heroku availability correlates pretty strongly to AWS US EAST availability. We had a couple of times where there was a Heroku-specific issue but not for the last 7-8 months.

The only issue that I ever have is that about 1 out of 20 deployments (git push) will hang and need to be cancelled and done again.

I've used it for many years without facing any major problem. It's not hard at all to get used to it, it's documentation is outstanding and simple. We are close to 2020 and I don't think most of the existing companies or startups should still face old problems such as wasting time deploying code and calculate computing resources.

Be ready to pay a bit more than expected in the beginning if you're migrating from a big server. The application is probably not ready for the change and you have to keep improving it with time.

It's also important to consider that you can't save anything to the disc as it will be lost when your application restarts, so you have to think about using something like S3.

While Docker shines in providing support for volumes and stateful instances, Cloud foundry shines in providing support for deploying stateless services. Heroku shines in integrating with Git and using commits to git as hooks to trigger deployments right from the command line. But it does not provide on-premise solution that Cloud foundry provides.

Incentivized

Heroku has advantages over Docker, Google App Engine and AWS products, but it depends largely on your use case. If you are already in AWS, it's probably in your best interest to stay with AWS products. However, other "Cloud Formation/Orchestration" products like Docker are typically lacking the ease-of-use factor that allows you to get up and running with Heroku quickly.

• Positive impact, since it simplifies the deployment time by a huge margin. Without cloud foundry, deploying a code needs coordination with infrastructure teams, while with cloud foundry, its a simple one line command. This reduces the deployment time from at least few hours to few minutes. Faster deployments promote faster dev cycle iterations.
• Code maintenance such as upgrading a Node or Java version is as simple as updating the build-pack. Without cloud foundry, using web logic, the specific version only supports a specific version of Java. So updating the version involves upgrading the version of web logic that needs to involve few teams. So without cloud foundry, it takes at least few days, with cloud foundry, its a matter of few mins.
• Overall, happier Developers and thats harder to quantify.

Incentivized

• It has been critical in seamlessly operating our platform with runs all of our programs.
• It has been impressive with its ability to scale quickly which results in the growth of our work.
• It allows for tracking of different features which allows for quick problem solving which saves us time.
