You might have missed the news over the weekend that Broadcom is in talks to buy VMware. As of right now this news is still developing so there’s no way of knowing exactly what’s going to happen. But I’m going to throw my hat into the ring anyway. VMware is what Broadcom really wants and they’re not going to get it.
Let’s break some of this down.
Broadcom isn’t just one of the largest chip manufactures on the planet. Sure, they make networking hardware that goes into many of the products you buy. Yes, they do make components for mobile devices and access points and a whole host of other things, including the former Brocade fibre channel assets. So they make a lot of chips.
However, starting back in November 2018, Broadcom has been focused on software acquisitions. They purchased CA Technologies for $19 billion. They bought Symantec the next year for $10 billion. They’re trying to assemble a software arm to work along with their hardware aspirations. Seems kind of odd, doesn’t it?
Ask IBM how it feels to be the dominant player in mainframes. Or any other dominant player in a very empty market. It’s lonely Continue reading
Today on the Tech Bytes podcast we talk with Managed Service Provider (MSP) and VMware partner of the year Softchoice on how Softchoice helps customers navigate multi-cloud and hybrid cloud deployments using VMware. We cover details about two real-world Softchoice/VMware customer use cases: a Major League Baseball team and a financial services firm.

Currently, in 2022, the CCDE exam version is version 3. There are many new changes in CCDE v3 compared to CCDE v2 and in this blog post, some are the new changes will be explained, also for the things that stay the same will be highlighted as well. Also, I will share my takes in the post about these changes.
Before starting the technical changes, let’s start with the exam result announcement change.
CCDE v2 exam has been announced in 8-12 weeks. This was effectively allowing CCDE exam candidates to schedule the exam two times maximum in a year.
Students wouldn’t schedule the exam if they fail because the announcement date and new exam date were usually overlapping.
This changed anymore.
With CCDE v3, exam results are announced in 48 hours. It is almost like CCIE exams.
CCDE v2 Lab/Practical exam was done in Professional Pearson Vue Centers. There were 300 of them and done in many different countries.
Unfortunately, this change may not be good for many exam takers as Cisco CCIE Lab locations are not available in many countries and are not as common as Continue reading
BGP Allowas-in feature needs to be understood well in order to understand the BGP loop prevention behavior, But also, why the BGP Allowas-in configuration might create a dangerous situation, and what are the alternatives of BGP Allowas-in will be explained in this post.
BGP Allow-as-in feature is used to allow the BGP speaker to accept the BGP updates even if its own BGP AS number is in the AS-Path attribute.
By default EBGP loop prevention is, if any BGP speaker sees its own AS Number in the BGP update, then the update is rejected, thus the advertisement cannot be accepted. But there might be situations to accept the prefixes, thus there are two options to overcome this behavior.
Either accepting the BGP update even if the AS number is in the AS-Path list, with the BGP Allow AS feature or changing the behavior with the BGP AS Override feature.
Without BGP Allowas, let’s see what would happen.
In this topology, Customer BGP AS is AS 100. The customer has two locations.
Service Provider, in the middle, let’s say providing MPLS VPN service for the customer.
As you can understand from the topology, Service Provider Continue reading

Back in the early days of the Internet, you could physically see the hardware where your data was stored. You knew where your data was and what kind of locks and security protections you had in place. Fast-forward a few decades, and data is all “in the cloud”. Now, you have to trust that your cloud services provider is putting security precautions in place just as you would have if your data was still sitting on your hardware. The good news is, you don’t have to merely trust your provider anymore. There are a number of ways a cloud services provider can prove it has robust privacy and security protections in place.
Today, we are excited to announce that Cloudflare has taken three major steps forward in proving the security and privacy protections we provide to customers of our cloud services: we achieved a key cloud services certification, ISO/IEC 27018:2019; we completed our independent audit and received our Cloud Computing Compliance Criteria Catalog (“C5”) attestation; and we have joined the EU Cloud Code of Conduct General Assembly to help increase the impact of the trusted cloud ecosystem and encourage Continue reading
