Looking ahead to the network technologies of 2023
Virtual networking will drive NaaS evolution, and cloud-hosted security options will explode.
How to reduce 2023 network costs: The cloud
Enterprises that used cloud networking as part of their network strategy cut network costs 5% to 50%
Data-center requirements should drive network architecture
Accept that the cloud is now part of the data center and needs to be incorporated in a low-latency mesh that supports modern applications.
Networking for remote work puts the emphasis on people, not sites
Remote work and the cloud have taught us to focus on connecting people to the applications and information resources they need rather than focus on pure site-connectivity goals.
How SASE might improve worker productivity and make CFOs happy
SASE can deliver needed information for more workers and for less cost than MPLS VPNs providing comparable connectivity.
Network availability: Are you your own worst enemy?
As network complexity grows, so does the complexity of dealing with it effectively.
What are virtual routers and how can they lead to virtual data centers?
With routing software deployed on off-the-shelf hardware, enterprises can reap the benefits of virtual routing that can extend to data centers and promote savings.
Network security depends on two foundations you probably don’t have
Before adding more layers to network security, consider the benefits of explicit network permission, backed by AI-driven traffic analysis.
Why it makes sense for Broadcom to buy VMware
Broadcom’s chips plus VMware software could be the bridge that connects applications in data centers with the cloud.
Redefining NaaS: It’s the internet
Network-as-a-service is popularly defined as expensing network technology and management rather than doing it yourself, but there’s a better way to look at it.
Look to Google to solve looming data-center speed challenges
Google’s Aquila project is establishing a model for high-performance meshing that can handle the most demanding data-center workloads.
Surprise! The internet of things doesn’t necessarily include the internet
Connected devices need a safe, reliable network of things (NoT) that ties them together, but that glue is likely IoT-specific protocols, not the internet.
Private 5G: 4 things that determine if you need it
Private 5G is a major step, so consider what devices need it, whether they move around and require privacy, and whether Wi-Fi you already have meets the need.
MPLS, SDN, even SD-WAN can give you the network observability you need
The ‘best’ traffic paths chosen by routers in a network won’t necessarily be the fastest ones.
Basing network security on IP addressing: Would it be worth it?
Rather than layering security onto networks, the networks and carefully managed authorization policies can hinder attacks, but at an administrative cost.
How to build a high-speed network for the metaverse of things
Today’s technology could build a low-latency, meshed optical network supporting real-time metaverse applications.
Surprise! The metaverse could be great news for the enterprise edge
High-bandwidth, low-latency services needed to support the metaverse could also mean a better, cheaper way to provide access for edge applications like IoT.
Virtual networks need a rethink to meet hybrid-, multi-cloud demands
Switch virtual-network providers if yours lacks a good plan to support ever more dynamic workloads.
5 best practices for making smart-building LANs more secure
Smart-building controllers can reduce risk of smart devices being used as entry points to the LAN, but they should be chosen and managed carefully.
