Containers.Containers were built for scale. You can spin up one or a hundred new containers in milliseconds, which makes automation and orchestration with native cloud tooling a breeze. Scale is so innate to containers that the real question with scale is, "How far do you want to go?" ...
What is a VM? Containers vs VMs: Which should you use? Using containers and VMs in CI/CD pipelines Containers and virtual machines (VMs) are two approaches to virtualization, or the creation of virtual — as opposed to a physical — versions of computer hardware platforms, storage devices, ...
One of the biggest advantages to a container is the fact you can set aside less resources per container than you might per virtual machine. Keep in mind, containers are essentially for a single application while virtual machines need resources to run an entire operating system. For example, if...
The virtualized container environment is arranged differently. With containers, a host OS, such as Linux, is installed on the system first, and then a container layer -- typically, a container manager, such as Docker -- is installed atop the host OS. The container manager provides the hypervi...
Vlad Iovanov from SUSE shared the results of the benchmark that compared performance of VMs to containers. His presentation was based on the session he and his colleague Jeff Hobbs delivered at the recent Cloud Foundry summit in Basel. Vlad noted that the main goal behind the benchmark “was...
I still believe VMs provide better security than containers, but we have to look at the safety of VM systems with clear eyes. I plan to discuss hypervisor weaknesses in more detail in the future. Also, containers and VMs are often combined. There is much yet to be said. Related content ...
For this reason containers offer better protection at this stage of an attack than a legacy VM application, and they are probably on a par with VM architectures that use separate VMs by function. Server vulnerabilities happen, but the much more common attack point is to gain access to a ...
When people talk sprawl and over-proliferation of virtual machines and services, the main concern lies in managing and administrating the resources. When it comes to terminating machines or containers, Docker has a clear advantage, which is image determinism. Since Docker containers maintain a clear...
March 1, 2022: Corrected note about database snapshots with multiple database containers in SAP HANA Large Instances high availability and disaster recovery on AzureFebruary 28, 2022: Added E(d)sv5 VM storage configurations to SAP HANA Azure virtual machine storage configurationsFebruary 13, 2022:...
Containers are not a Linux isolation primitive, they merely consume Linux primitives which allow for some interesting interactions. They are not perfect; Nothing is.We can make them better by reducing some of the complexity and building hardening features around them which is a goal I have been ...
