Warum Container?
Container machen Anwendungen unabhängiger von der Umgebung, in der sie ausgeführt werden. Sie agieren damit ähnlich einer virtuellen Maschine (VM). Container verbrauchen also im Vergleich zu VMs deutlich weniger Ressourcen wie Rechenleistung, Hauptspeicher und Speicherplatz.
Welche Vorteile bieten Container?
Vorteile von Containern
- Weniger Overhead. Container benötigen weniger Systemressourcen als herkömmliche oder Hardware-Umgebungen mit virtuellen Maschinen, da sie keine Betriebssystem-Images enthalten.
- Erhöhte Portabilität.
- Konsistentere Betriebsabläufe.
- Höhere Effizienz.
- Bessere Applikationsentwicklung.
What is the difference between containers and Microservices?
A common misconception is that microservices are equivalent to Containers, but they’re not. Let’s look at containers running on Docker. Typically an app is running in a container, but with microservices, little pieces of an app can sit at different levels of infrastructure within your environment.
How do you scale microservices in containers?
“The optimal way to scale microservices in containers is to deploy only one service per container,” Kavis says. Containers are commonly referred to as “lightweight,” “lean,” or with similar adjectives – but you must ensure they stay that way.
What is a container service?
A Container Service removes the need for a guest operating system. All of the containers, binaries, libraries, and apps run on a container runtime but share the host operating system. This makes the container much lighter than a virtual machine, and it takes a fraction of time to boot up and build out when needed.
What is the difference between an app and a microservice?
Typically an app is running in a container, but with microservices, little pieces of an app can sit at different levels of infrastructure within your environment. You may have a database you’re considering that provides a service to your organization. Maybe this database supports ten applications.
