Go vs Ruby

We as a company specialize in Golang; however, that’s not why we thought of penning down a blog on Go vs Ruby. In recent times a lot of our clients have been requesting to migrate their existing enterprise systems from Ruby on Rails to Golang. Since this was becoming a fairly regular request, we thought of putting together the main reasons for these requests. So here we have the 5 main reasons Businesses want to switch from Rails to Golang. Let's talk about how the battle of Go vs Ruby is heating up:

Ruby Performance:

Almost all the Clients complained of slow performance; which was leading to concurrency bottlenecks. This hits performance and time taken to complete a job is not satisfactory. In contrast, Golang was able to handle a huge load of concurrent requests without slowing down the performance of a program. This is why enterprises with web-based applications, found that Golang based programs were able to handle several users at one time without ever mal performing.


Scalability is almost always a result of concurrency. An application which can handle concurrent requests will more likely be scalable. We realized when Rails gets to a significant enough scale the runtime speed diminishes significantly resulting in poor performance. Golang, on the other hand, outshines this test by scaling automatically to multiple cores. This ensures that organizations don’t have to worry about migrating costs once the business scales up.

High Infrastructure Costs:

Ruby like most languages of the past consume more compute resources than necessary resulting in high infrastructure cost. This happens because some of the IO libraries do not support multithreading as they keep hold of the GIL (Global Interpreter Lock). As a result, requests get queued up behind the active request and lead to performance issues. The only way to work around this is switching to a multiprocess setup which then leads to higher infrastructure costs. In Go vs Ruby, Golang comes as a breather of relief for clients who migrate to Go. It uses isolated goroutines, which helps save on resources such as CPU and memory. This type of resource efficiency not only helps in faster performance but also brings about lower infrastructural costs.

Cost of patching errors:

Active Record is a hard dependency for many of the RubyGems. The drawback to this is that the domain becomes tightly coupled to persistence mechanism. This leads to some bad architecture decisions. On the other hand, Golang comes with a built-in error type and any deviation from the standard go practices on part of the developer causes an automatic prompt. It leads to fewer chances of error and saves on costs of patching these errors.

Huge Go-To-Market time:

This happens because for Ruby on Rails Server Configuration and Management is time-consuming. That’s a lot to be done, even before a Rails app is deployed on a production server. The process of deployment doesn’t stop once the app is up-and-running. Ruby requires support for pushing updates to all servers. For this the system needs to support stack swapping or rolling upgrades to migrate to newer versions of the application. This while the continuously supporting real-time incoming requests of the previous version.So basically it gets to be a tedious process. Golang based applications, on the other hand, have no dependencies outside the standard library and require no additional data files at runtime; making them simple to deploy and maintain.

Thus to sum it all up Golang is like the new dependable car in town; ready for a drive. In spite of being new, it is giving leading developing languages a run for their money. Once you invest in Golang for all your enterprise development needs, chances are that you are not migrating to another language for years to come. From the above comparison, of go vs ruby it is safe to say that Golang is the better performer when it comes to deciding upon go vs ruby.
