Description

Go is one of the most powerful, efficient, and highly-performant programming languages. It has seen an increased rate of adoption mainly because it is lightweight, easy to use and displays great robustness when performing in a variety of domains. Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. Go (often referred to as golang) is a programming language created at Google in 2009. It is derived from C with additional features such as garbage collection, type safety, dynamic-typing capabilities, additional built-in types, and a large standard library. If you're interested to build a foundation for your applications so as to improve its performance, then go for this Learning Path.
Packt’s Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it.
The highlights of this Learning Path are:
Learn encoding strategies and some functional design patterns for GoDeal with various storage libraries for accessing data storage systems such as MySQLTest your application using advanced testing methodologies
Let’s take a quick look at your learning journey. This Learning Path starts off with basic tutorials on the language leave off. You can immediately put into practice some of the more advanced concepts and libraries offered by the language while avoiding some of the common mistakes for new Go developers. Initially you will work upon I/O file systems and command line tools. Error handling feature of Go will help you with structured logging, logging with context package, etc. You will also learn about databases and storage using MySQL and NoSQL with MongoDB. You will also come across microservices that improves your Go applications.
Further, this path explores applications that interact with users, such as websites, command-line tools, or via the file system. It demonstrates how to handle advanced topics such as parallelism, distributed systems, and performance tuning. Lastly, it finishes with reactive and serverless programming in Go. You will learn about serverless programming and also tips and tricks to improve performance of your application.
By the end of this Learning Path, you will be able to bridge the gap between basic understanding of Go and use of its advanced features to build foundation for your applications.

Aaron Torres received his master’s of science degree in computer science from New Mexico Institute of Mining and Technology. He has worked on distributed systems in high performance computing and in large-scale web and microservices applications. He currently leads a team of Go developers that refines and focuses on Go best practices with an emphasis on continuous delivery and automated testing. Aaron has published a number of papers and has several patents in the area of storage and I/O. He is passionate about sharing his knowledge and ideas with others. He is also a huge fan of the Go language and open source for backend systems and development.
