About the course:
Our instructor-led Microservices with Docker training course will give you hands-on experience designing and creating flexible and scalable services for your enterprise applications using this cornerstone containerisation technology platform.
You'll learn how to plan, build and implement streamlined services, in the form of lightweight containers which will allow you to modularise an otherwise monolithic architecture and take a more Agile approach to your enterprise / deployment architecture.
The course is suitable for all comers, with example code available to demonstrate microservices built on Java, Node.js, GoLang, and .NET Core. We'll cover software installation during the course so you just need to bring yourself and your laptop and an absorbent mind.
Does your whole team need to gain experience of designing and managing your microservices architecture? We would love to discuss your requirements as an in-house / remote training course might be the best option. Whether you are deploying in the cloud and / or on-premises, we can can take into account your tech stack, use cases and business domain in order to deliver a cost-effective and highly relevant tailored course. Get in touch to find out more.

Useful resources
Who should attend
This course is aimed at SysAdmins and Developers who wish to develop and deploy Microservices.
Prerequisites
Delegates should have some understanding of systems architecture and design. Experience of administering Linux or Windows servers may also be useful. Some basic editing of code will happen during the course, so experience with a language such as Java, C#, C++ would be advantageous.
Live, instructor-led online and on-site training
We appreciate that you need flexibility to fit in with new working situations - whether you're an individual, part of a distributed team, or simply have projects and deadlines to meet.
Our remote training can take place online in a virtual classroom, with content split into modules to accommodate your scheduling challenges and meet your learning goals. Get in touch today to find out how we can help design a cost-effective, flexible training solution.
As soon as it's safe, we'll return to also offering the on-site custom training courses and programmes upon which we've built our reputation.
