Containers: the most complete managed solution currently available on the market.
Containers are an innovative method of virtualization, that simplify significantly the deployment and the processes implementation, representing a valid alternative to Virtual machines.
The Cloud world is gradually revolutionizing thanks to containers, meaning virtualization and isolation of processes and not of the entire machine. The outstanding feature is that containers create an isolation boundary at the application level rather than at the server level. This isolation means that if anything goes wrong in that single container it only affects that individual container and not the whole VM or server.This abstraction level brings several benefits that we will see in the following lines.
In addition, containers are smaller than virtual machines and they request less computing power. They don’t need the hypervisor as the VM and respond to the need of flexibility and saving necessary to use the Cloud resources. Containers are an advanced technology unique for its modularity and compatibility, which determines their great business advantage on the market.
VIRTUAL MACHINE VS CONTAINER
BENEFITS OF CONTAINERS
- Isolation of resources: RAM, processes, devices and networking are virtualized at the Operating System level, and the applications are isolated from each other. This means that you don’t have to worry about conflicts of dependencies or shared resources, because each application has defined limitations in the use of resources.
- High scalability: con i container è possibile non solo scalare le risorse verticalmente, ma anche orizzontalmente. Tutto questo in tempo reale e in modo semplice ed automatizzato.
- Portability: thanks to the standardization approach, containers enable the portability of resources, by reducing issues about the displacement of applications through the cycle of development, testing and production. Applications can be deployed in an easy and secure way independently from the environment and new features can be released more easily.
- Operating efficiency: with containers you can run more applications on the same instance and specify the right amount of resources which should be used, by ensuring their optimization. Containers are lighter than VM and make the system more agile, by increasing the operating efficiency, the development and the management of applications.
