In this new video, our colleague explains how to configure a Global Service Load Balancing service to scale and create high availability among all our public services in different data center locations. The flexibility of this technique is shown in these examples, active-active data centers and active and automatic disaster recovery scenarios. In addition, GSLB...

Global Service Load Balancing, as well known as GSLB, is a load balancing technique that permits to build fault tolerance, automatic disaster recovery, load balancing across WAN servers and improved latency among different data center sites using the distributed DNS protocol. For that reason, we’ve compiled a technical article to show how easy is to...

The recent Intel vulnerabilities are going to affect to all our data centers for a while. Let’s review all the keys in the following article and learn the preventive solutions to palliate the threats. https://www.relianoid.com/knowledge-base/misc/intel-firmware-and-processor-kernel-memory-leaking-vulnerabilities/

Usually, during an infrastructure design it’s required to study the requirements of the services and estimate the resources needed to avoid oversizing or undersizing the platform, but even we need to decide between hardware or virtual environments where the first one provides more performance and less latency, but the second one flexibility. Every case should...

Networking security is a mandatory requirement during data exchange and processes interconnection, but it is well known as well that increased security implies the needs of much more resources to analyze, detect and protect at different layers all the communications. In order to palliate these heavy requirements, some hardware vendors dedicates special offload techniques to...

Whatsapp status or Whatsapp downtime has been one of the most searched keyword in the last hours due to the outage registered of servers all around the world, mainly America’s East Coast and Western Europe, during approximately 3 hours the 3rd of May.

In our challenge to ease availability, we’ve been building a new Disaster Recovery tool that permits to setup a ZNA64 3300 Hardware Appliance in less than 3 minutes using just a Pen Drive. Such tool is able to create custom and already configured firmware files for the Hardware Appliances and restore it in less than...

Last Netdev 1.1 Conference in Seville (Spain) was presented a design of a new sophisticated load balancing infrastructure which will permit not only more performance with less resources but also a simplification and unification of user space commands for networking handling. This is the base of Zen Load Balancer technology and the reason of our...

ZVNcloud is a Load Balancing as a service solution developed in the cloud powered by #ZenLoadBalancer technology and #DigitalOcean cloud platform to orchestrate load balancing services on demand. Thanks to this technology users can deploy a virtual load balancer in cloud in more than 12 Datacenters around the world in less than 2 minutes. The...
