Introduction to Unikernel: Building and Deploying Lightweight, Secure Applications
Have you ever wondered what it would be like to have everything in the world just for yourself — where every resource and every service is just for you? Imagine you have rented a private villa on a small, quiet island. Everything in the villa — the rooms, the pool, and the beach — is just for you. No other guests can use anything there, and the staff are there just for you. Isn’t that exciting? I’m sure it is!
This concept also applies to applications, which are given their own space to work in without interference from others and without sharing resources. Any application could thrive in such an environment. So, the question is: “Does such an application environment exist?”
Enter unikernels — a unique application environment that can provide an exclusive environment just like your private villa. They are compact, single-application virtual machines, boosting speed, efficiency, and security.
In this article, we will take a closer look at what unikernels are, explore the different types of unikernels, discuss their benefits and limitations, and learn how to create and deploy a simple Nanos application (a type of unikernel) on AWS.
