How could an automated VMOC, as described in the presentation, be used to help those affected by Hurricane Harvey?
2.Containers are facilitating rapid, agile development like never before. But questions still persist on container basics, namely:
1-How do they differ from virtual machines?
2-If containers are, by their nature transitory and disposable, how can you utilize them alongside persistent storage?
3-How do they complement existing virtualization and/or orchestration solutions?
Can containers be used to automate satellite ground systems.
Explanation / Answer
1. VMOC ensures that the first responders are provided with the “right data” –Not every possible scene, just the scenes that are actually needed for a given set of circumstances Reduces costs by only requesting data that is needed –Good steward of resources (reduced data requests) – makes this a more partner friendly system –VMOC reduces system latency and improves operational responsiveness .

1.Operating system (OS) virtualization became popular over last , which enable software to run predictably and well when moved from one server environment to another. Containers provide a way to run these isolated systems on a single server.
VMs and Containers different from each other, because containers provide a way to virtualize an OS in order for multiple workloads to run on a single OS instance, but VMs, the hardware is virtualized in order run multiple OS instances. Containers’ speed, agility and portability make them yet another tool to help streamline software development.
2. containers is their transitory and disposable nature. A container can used in seconds, But while developing them, persistent storage was not supported on containers. Then later on companies started ways to integrate them into the system
a) Docker data volumes: provide the ability to create a resource that can be used to persistently store and retrieve data within a container. Data volumes sit outside than exist on the host file system, so they're more efficient to read and write to.
b) a dedicated container is used to host volume and to mount that into other
c) A third option for persistent data is to mount a local host directory into a container.
d) containers are able to connect to external storage platforms through storage plugins.
3) In containers, the operating system is virtualized not physical system as in virtual machines.
Container orchestration replaces the need for configuration management for your deployments, making deployment robust and repeatable. If a deployment fails or a release needs to be rolled back for some reason, containers make falling back to a previous version straightforward,
You can also run containers on virtual machines. Virtualization provides enterprises with a great deal of flexibility in using their computer resources.
