Worth Reading: Why Must Systems Be Operated?

Every now and then I find an IT professional claiming we should not be worried about split-brain scenarios because you have redundant links.

I might understand that sentiment coming from software developers, but I also encountered it when discussing stretched clusters or even SDN controllers deployed across multiple data centers.

Finally I found a great analogy you might find useful. A reader of my blog pointed me to the awesome Why Must Systems Be Operated blog post explaining the same problem from the storage perspective, so the next time you might want to use this one: “so you’re saying you don’t need backup because you have RAID disks”. If someone agrees with that, don’t walk away… RUN!

Server sales projected to decline 10% due to coronavirus

Global server sales had been projected to grow by 1.2% compared to the most recent quarter, but the chaos wrought by the coronavirus in China will cause sales to decline 9.8% sequentially, according to DigiTimes Research.DigiTimes is an IT publication based in Taiwan. Its proximity to Taiwanese and Chinese vendors gives it some good sources, but it can also be way off target. However, the signs are piling up that coronavirus is causing some real mayhem.For example, DigiTimes also reported that less than 20% of Chinese factory employees would return to work after an extended Lunar New Year break due to the coronavirus outbreak, and that many components plants in China have decided not to restart production until February 25.To read this article in full, please click here

BrandPost: Top 2020 SD-WAN Predictions

We've seen many transformative changes in the market over the past few years. In 2019, for example, we witnessed router-centric and basic SD-WAN offerings beginning to fall short of expectations as enterprises began shifting toward a business-first networking model. We also saw an emphasis on cloud security, along with a bond forming between SD-WAN and UCaaS. We began to see a new set of emerging requirements for multi-cloud deployments, and the promise of 5G beginning to materialize.So, what's in store for 2020? This is sure to mark another year of continued WAN transformation and a year in which enterprises can begin to realize a multiplier effect from their cloud investments. As the market continues to gain momentum, here are my annual predictions for SD-WAN and the future of the WAN edge infrastructure market.To read this article in full, please click here

Supercharging Workload Security in Your K8s Cluster

Introduction

2019 was a big year for Kubernetes adoption, and 2020 is sure to exceed that pace. Already, we have seen a large number of organizations migrating their workloads to Kubernetes (k8s) both in public and private clouds as they embrace a hybrid cloud strategy. With so much at stake, what are you currently using for network security inside your k8s cluster?

 

Quick Retro

Let’s take a step back to a time when you were deploying applications to VMs in AWS, GCP or Azure (in the case of public clouds) or vSphere, etc. in private clouds. One of the most important tasks before provisioning infrastructure and deploying applications was to chalk out firewall considerations. These requirements were fulfilled using security group rules in the case of AWS or firewall rules in GCP. We all understand their importance. But doing the same involving Kubernetes was extremely challenging. Today, we can solve those problems for you with just a few clicks.

 

Present Scenario – What If?

Most recently with the increase in k8s adoption we have seen operations and platform teams hustling to implement a plethora of monitoring tools, logging backends and CI/CD tools. While all of this is Continue reading
