VLAN vs. VXLAN — what’s the difference and is one better than the other?

VM, VDI, VIM, NFVI, VLAN, VXLAN, VNF - the famous ‘V’ that dominates today’s IT world stands, of course, for ‘Virtual’. Every day we use virtualized servers, storage, desktop or networks without even realizing it. The convenience, cost-saving, enhanced features and security are just some of the reasons why we start using virtualization and often never look back. The same is true for computer networking, where a single physical network can host multiple separated, logical (virtual) networks that may have different topologies and feature sets or even carry traffic of different customers without interfering with each other.

Management vs. Control vs. Data Planes in a Network Device

An application, a system or even a simple device is made up of several components, each of which performs specific functions to the best of its ability, while leaving other tasks to other components which are dedicated to taking care of them. For example, a web application may consist of a HTTP server which provides the UI, a database server which keeps information about users, and a content server where images and videos are stored. Such an approach to dividing responsibilities is no different in networking devices, where hardware and software components work together to analyze and forward traffic according to the configuration applied by the administrator.

How to successfully provide great UX in network applications?

When you think about designing a user experience, usually the first examples to come to mind are mobile apps. But network applications need good UX design as well. They have specific challenges, for example, visualizing large amounts of data or processing complex commands. Read on to find out about our solutions for bringing a positive user experience to networking applications, and why it's important. UX stands for user experience. It's not just about nice and tidy interfaces - the topic goes much deeper into understanding the user's behavior, expectations, emotions, and perceptions.

The modern, interoperable DC — Part 3: Seamless and secure connectivity for edge computing and hybrid clouds (video)

In the third part of our “Modern DC” webinar series we focus on connectivity with resources located beyond the local data center, somewhere in the Internet. This includes extending Layer 2 and Layer 3 tunnels to public clouds (such as AWS, Azure and GCP), branch offices, Edge Computing servers and IoT devices based on single-board computers.
