This is a guest blog post by Dave Crown, Lead Data Center Engineer at the State of Delaware. He can be found automating things when he's not in meetings or fighting technical debt.
In a recent blog post, Ivan postulated “You’d execute a REST API call. Any one of those calls might fail. Now what? ... You’ll have absolutely no help from the orchestration system because REST API is not transactional so there’s no rollback.” Well, that depends on the orchestration system in use.
The promise of controller-based solutions (ACI, NSX, etc.) is that your unicorn powered network controller should be an all seeing, all knowing platform managing your network. We all have hopefully learned about the importance of backups very early on our careers. Backup and, more importantly, restore should be table stakes; a fundamental feature of any network device, let alone a networking system managed by a controller imbued with magical powers (if the vendor is to be believed).

There were no challenges filed. Therefore the election results stand:
The term of office for all 4 of these Trustees will be 3 years, commencing with the 2019 Annual General Meeting of the Internet Society, 26-28 July.
The Elections Committee congratulates all of the new and renewing Trustees and expresses its gratitude once more to all the candidates and to everyone who participated in the process this year

If you had to pick two really hot topics in the networking space right now, you’d be hard-pressed to find two more discussed than SD-WAN and microsegmentation. SD-WAN is the former “king of the hill” in the network engineering. I can remember having more conversations about SD-WAN in the last couple of years than anything else. But as the SD-WAN market has started to consolidate and iterate, a new challenger has arrived. Microsegmentation is the word of the day.
However, I think that SD-WAN and microsegmentation are quickly heading toward a merger of ideas and solutions. There are a lot of commonalities between the two technologies that make a lot of sense running together.
SD-WAN isn’t just about packet switching and routing any longer. That’s because networking people have quickly learned that packet-by-packet processing of traffic is inefficient. All of our older network analysis devices could only see things one IP packet at a time. But the new wave of devices think in terms of flows. They can analyze a stream of packets to figure out what’s going on. And what generates those flows?
Applications.
The key to the new wave of SD-WAN technology isn’t some kind of magic method Continue reading

Having been around the block a time or two, I’ve seen my share of trade show event booth giveaways and all manner of tchotchkes, most of which find their way to a trash can before the visitor gets home. For the upcomingDell Technologies World 2019in Las Vegas, we wanted to do something different – something that would impact the world in a positive way.
So, we’ll be raffling off 100 “adoptions” of real North American pikas, as part of the National Wildlife Federation’s Adopt-a-Pika program.
A pika is a small mammal, closely related to rabbits – and it’s in trouble. As the NWF explains, “Pikas live in high mountain ecosystems that are cool and moist. Higher temperatures can cause the pikas to overheat.”
As global warming brings higher temperatures to the pika’s habitat, it’s creating real problems. Pikas can’t just go find higher ground where it’s cooler – because that higher ground is their natural habitat.
“Without our protection and help, American pikas could be the first species with the distinction of going extinct due to global warming,” the NWF says.

To avoid that distinction, the NWF launched the “Adopt an Continue reading

This blog post will provide a deep dive on the distributed firewall (DFW) on VMware Cloud on AWS (VMC on AWS). Let’s start with the basic concepts of a distributed firewall:
The distributed firewall is an essential feature of NSX Data Center and essentially provides the ability to wrap virtual machines around a virtual firewall.
The virtual firewall is a stateful Layer 4 (L4) firewall – it’s capable of inspecting the traffic up to the Layer 4 of the OSI model: in simple terms, it means they look at IP addresses (source and destination) and TCP/UDP ports and filter the traffic based upon these criteria.
What’s unique about our firewall is that it has contextual view of the virtual data center – this means our distributed firewall can secure workloads based on VM criteria instead of just source and destination IP addresses.
Traditional firewalling is based on source and destination IPs – constructs that have no business logic or context into applications. Our distributed firewall can secure workloads based on smarter criteria such as the name of the virtual machine or metadata such as tags.
This enables us to build security rules based on business logic (using Continue reading
