Golang is discussed here as an open source programming language providing nice features for DevOps while developing highly competitive concurrent programs and performing clear outcomes for outsourcing software companies.
As I came back home today, my head was full of thoughts like a hurricane, having swapped "IT engineer" with "DevOps," and "complex dependency trees" with "vendoring concept." There were two possible reasons for such a case with my mind and emotional state: either the hot and exhausting summer routine, or the fact that my friend has broken into the DevOps career recently and shared the burdens of info on a variety of IT issues, including his plan how to deal both with the customers and the developers efficiently. To tell the truth, his plans looked like the Google office: bright, smart, going further, and...boosting my "Oh-I-am-an-old-school-conservative-business-analytic" thoughts.
Golang Basic Features
What I really heard and know about Golang for DevOps is that it’s a kind of language easily used for any project scope purposes. Once we’ve got a request to rewrite chatbot for QArea client’s forum. So, the demands were outlined (deadlines were hardly met, I’d like to specify) and to facilitate the process I dove into the code myself. With the course of time, this chatbot had gotten many complicated things that became old, and the rest of them turned out to be plain and simple. It could be redeveloped with any language; it was decided to use Go, which turned out to be manageable and painless to apply.
Since that very moment, I’ve been extremely interested in the advantages of Golang for the developers under the DevOps approach. I’ve talked to the professionals from our QArea team, testing the ground, asking various questions. So now I want to share with you what I have already picked up: what Go can propose for DevOps.
Golang Development Pros and Cons
Here two lists will be placed: what Go lets developers do to perform better while meeting the desired demands, and how it contributes to IT team management (considering Go proposes some extra value in this field).
So, here are the reasons Golang is vastly implemented in DevOps tools and in writing code in general:
- Simple and concise syntax. No developer employed by a software services company will be terrified while operating a Golang web framework.
- Concurrency. One can be sure this feature was in the minds of the Go creators. It’s performed through goroutines and channels. It’s much simpler to achieve collateral execution (no locking).
- Speed. What is surprising (and trust me, because I’ve interviewed a lot of specialists. Their opinions were split on the other issues, but concerning this one, they voted unanimously) is that whether small scripts or huge data sets are written, they perform great. This language grants you speed. Once 5000 concurrent connections tests were completed, the failure rate for Java, PHP, and Node was really significant while Go performed well.
- No more complex dependency trees. Golang is quite a quirky one; it compiles all the dependencies into the binary.
- A minimal amount of runtime errors (since it’s a statically typed language).
- Function closure is a really amazing feature. Having experienced it once, you’ll like it forever.
Considering all the points mentioned above, once you have a request for any software development company, it’s possible to be sure your order will be designed under the "Do one thing and do it right" slogan, with understandable and reusable code as an outcome.
Non-Developer Benefits From Go
Go's competitive advantages for IT team management in a programming company are the following:
- You don't have to wrap your mind around how to involve a new specialist in the project; even if he/she is not an advanced developer who has experience with Go, it’s much simpler to add the specialist to the team (one of my colleagues specified, "In spite of the fact I’ve already gained ‘my best practices’ and ‘how to do it better’ pieces of advice, it’s still easy for me to introduce even not-so-talented and really slow professionals to a Go project," either a web server or Go web application design). One needs a week to be fully involved and that is the worst case.
- Analytics (yep, sometimes they need to see the code as well) are aware of it easily.
- Projects are growing; sometimes there’s a need to return to your own or your colleagues’ code, and I did hear that many programmers' experience that it’s convenient to do with Go. No complications at all.
- Having looked through a range of Go-based works, I’ve made a conclusion. Obviously, Go is pushing the design toward less deep abstractions, and that contributes to the outcome judging by code clarity and readability.
Phew, so much has been discussed (and it is so useful to be aware of Go peculiarities for any web development company), but the rest of the data in my head is too big to be placed here. Let’s take a break for coffee or tea. I’m actually dreaming about the time when artificial intelligence will assist in quick lunch-making at our kitchens while we’re discussing "Go or not Go" here surfing the net. By the way, we could surely speak about machine learning in Go as well: haven’t you heard? It’s possible to design algorithms getting input data and predicting the output. Nowadays, developers have the opportunity to deal with machine learning libraries (as well as with Go network libraries) created in Go (I'm glad to direct you slightly by naming them: GoLearn, which is simple and customizable; GoML, which comprises many models, making one learn in an online communicative reactive manner; and the intriguing Gorgonia, written totally in Go).
A Specialist's Personal Insights Into Go
You know, few things on Earth are so perfect that they have no chance to be improved (maybe the Earth itself); there are some insights about Go, tiny drawbacks coming along, which on a constant basis could make them an eyesore both for the developer and the user:
- One of them is the absence of the possibility to restart code while its being executed; once you need to renew Go simple web server code, the server process should be canceled and the new one should be launched. It influenced the accessibility of the server during code updates.
- Go’s deceitful similarity to C-like languages. Under the absence of a wish to get acquainted with at least the basic manual, funny "select" statements with "default" active appear. They might be funny, but anyway, they could lead to "Wow, in this Go of yours, TCP reader occupied all the CPU all of a sudden."
To sum up all the scratches given above, I’d like to prevent you from treating Go as the simplest language ever- beyond the border of its simplicity, the dragons could appear. Anyway, DevOps with their mission to save the world (I’m just kidding, read, please, "save the user") could apply Go to solve real-life problems.
See you and Go to implement any kind of project (from creating a server with Go to designing Golang web app).
