In all seriousness: in the world of IT, what exactly are container, anyway For those who are not very popular? trusts come with the container and why you hear so much about it now, this post is for you.
you have an operating system (OS).
you have some applications (Apps) is running on your operating system.
In most cases, they are packaged together as a "virtual machine".
And then happens virtualization. Hypervisors happen - and it runs multiple copies of a virtual machine can have on a hypervisor. In many cases, organizations are many instances of the exact same virtual machine on a hypervisor.
In the virtualized environment, all items of 10 virtual machines have 10 copies of the operating system and 10 copies of the app is running. The operating system itself is a lot of waste, since it pretty much the same code between different virtual machines is
Enter container - .., Which pair individual apps with an OS runtime component
So what is the benefit? They use the same server, but you do not have to duplicate your base system software, including the OS. With containers, you are able, without replication, your core system use to get full advantage of what each app requires when it needs it.
In a container-based environment, the system is setup so the OS component between all 10 copies of the machine shared - avoiding waste. Even though it's on the OS update, you do not need to update more than 10 copies of the machine or operating system.
Another advantage of a container that when a developer builds the container, it's pretty much remains unopened and untampered to run with all the way to the point there, which means that you error during installation eliminate or providing your application that uses happen with virtual machines. Also, a container may run unchanged on internal private cloud infrastructure and also for the public cloud can be without running shipped to repeat the container.
The benefits are not just resources to run your applications to make, but also a granular look at the performance of specific applications. In a pre-virtualization world, this was not the case. And, it is basically what the IT industry is very pleased to see the attraction on virtualization and containerization, very accurate.
And what about the dynamic between classic applications and how the development of new applications and the move to DevOps?
The classic waterfall scenario of "classic applications" - the app, development, testing and deployment model - is to lose it. Rapid development, iterative implementation of new applications is what the industry "DevOps" calls, and to gain more favor within the IT community. Container to bring back into the equation - the operation of data centers have never been as efficient managers new app development capable of
And the key here, really, the driver on the new frontier of DevOps is agility, speed and the need. to get applications to market faster than ever before.
