Unikernels is a smaller, faster and more secure alternative for distributing applications on cloud infrastructure. With NanoVM's OPS, anyone can run a Linux application as a unikernel without further coding

Building and deploying lightweight applications is turning into a simpler and more authentic procedure with the emergence of unikernels. Although limited in functionality, Unikernels offers many advantages in terms of speed and safety.

What are unikernels?

A unikernel is a highly specialized single-address-space machine image that is similar to the type of cloud applications that have come to dominate so much of the internet, but they are significantly smaller and have a single purpose

They are lightweight and provide only the resources needed. They load very fast and are much safer - having a very limited attack surface. All required drivers, I / O routines and support libraries are included in the single executable. The resulting virtual image can then be booted and run without anything else. And they often run 10 to 20 times faster than a container

Would-be attackers  can't drop into a shell and attempt to pick up control because there is no shell. They can't attempt to grab the system's /etc/passwd or /etc/shadow files because these files don't exist. Creating a unikernel is much similar to transforming your application into its own Operating system. With a unikernel, the application and the OS become a single device. You omit what you don't need, thereby removing vulnerabilities and improving performance many times over.

In short, unikernels:

• Provide improved security 
• So small footprints is the standard cloud apps
• Are highly optimized
• Boot extremely quickly

Are there any downsides to unikernels?

The only serious downside to unikernels is that you have to make them. For many developers, this has been a huge step. cutting down applications to exactly  what is needed and then producing a tight, smoothly running application can be complex due to the low level of the application. In the past, you must pretty much have been a system developer or a low-level programmer to generate them.

How is this changing?

Recently (March 24, 2019), NanoVMs announced a tool that loads all Linux applications as a unikernel. With NanoVM's OPS, anyone can run a Linux application as a unique kernel without further coding. The application will also run faster, safer and with less costs and overheads

What is NanoVMs OPS?

NanoVMs is a unikernel developer tool. It allows you to run all types of enterprise-class software but still has extremely tight control over how it works.

• Learn more from this expert analysis.
• Developers do not require any prior experience or knowledge to build unikernels.
• The tool can be used to create and run unikernels locally on a laptop.
• There is no need to create any account and only a single download and one command is required to execute OPS.
