Kubernetes is a platform for running applications and services. It manages the full lifecycle of container-based applications, by automating tasks, controlling resources, and abstracting infrastructure.
Istio is a configurable, open source service-mesh layer that connects, monitors and secures the containers in a Kubernetes cluster.
Cloud computing is the delivery of computing services over the internet ("the cloud") to offer faster innovation and flexible resources.
This abstraction allows for greater flexibility to use optimized techniques the infrastructure provider supplies. Declarative definitions also help reduce the technical debt of maintaining imperative code, such as deployment scripts, that can accrue over time....
We have the same kind of hiddenDateTime.Nowinput problem — the only difference is that it is located on a little bit higher of an abstraction level. To solve this issue, we can introduce another argument, again delegating the responsibility of providing aDateTimevalue to the caller of a new...
Virtualisation has inherent performance differences simply as a result of the abstraction from hardware and can pose problems troubleshooting time-based/dependent issues. Hosts without hardware extensions in the CPU may not allow access to specific resources. This is known as paravirtualisation, but is...
ARAID controlleris a device used to manage drives in a storage array. It can be used as a level of abstraction between the OS and the physical drives in the data center, presenting groups of drives as logical units. Using a RAID controller can improve performance and help protect data in...
No-code, in some sense, is a misnomer: There is plenty of coding involved, but it is behind the scenes, invisible to business users. The heavy lifting is done by the no-code tool providers that usedata abstractionandencapsulationto essentially hide the complexity of what users accomplish thro...
Virtualization is a technology that enables the creation of virtual environments from a single physical machine, allowing for more efficient use of resources by distributing them across computing environments. Using software, virtualization creates an abstraction layer over computer hardware, dividing a sing...
What is the role of an OS in virtualization? An OS can act as a host for virtual machines (VMs) by providing resources such as CPU, memory, and storage to multiple VMs running on top of it. The OS also manages the communication between the VMs and the physical hardware. ...
