The company will introduce a Virtustream addition of its enterprise hybrid cloud this year.
IP-CLOS provides scalable option for large scale Data Center for hosting providers or Infrastructure as a Service (Iaas) model. IP-CLOS model consists of spine and leaf layer switches, where leaf layer switches provides direct connectivity to Bare Metal Servers (BMS), hypervisor based servers or other network devices (e.g Firewall, Load balancer) for services layer. Each leaf device is connected to all spine devices through high speed link, connectivity between spine and leaf is IP based thus offering ECMP (equal cost multipath) load balancing over IP links.
The question arises why need IP-CLOS based Date Center, the main and primary reason is to remove the upper limit on maximum number of VLANs. In switching based Data Center (traditional 3-Tier i.e Core, Distribution & Access) or modern Data Center (Spine and Leaf based switching fabric or flat switching fabric e.g Juniper Virtual Chassis Fabric and Juniper QFabric) we still have an upper limit on available VLANs inside single Data Center i.e 4096. In IP-CLOS based Data Center VLAN values are not significant and once traffic received on leaf layer from sever/ external network devices it will be converted into VxLAN packets and will be identified by Continue reading
Seriously hard. We consume a huge amount of information daily. I see metrics like 10,000 to 100,000 words a day being consumed by each of us. Some of that will be subjective, some of it objective. Some of it will be fiction, some will be fact. Some? Who knows. Political propaganda with elements of truth. Some of it will incite emotion and some of it will aid in falling to sleep.
If you blog, do podcasts or write whitepapers for reasons not tied to your employment or cold hard cash income, have you ever asked yourself why you do it? What makes you want to share?
In a society where something is declared fake news because two parties don’t agree and freedom of speech is becoming one way, is it worth it?
If I need or want to learn something, I’ll go wide in the hunt for knowledge. Thanks to the ‘tinterweb, information is readily available. So much information is out there that we have the problem of validating what we read. Blogs have been a massive help to me over the years, especially when you read aligning and agreeing articles. The validation of “someone else Continue reading

Welcome to a new series where we interview Ansible experts on IT automation and ask them to share their direct experiences building automation solutions, as well as any insights they have regarding the state of the industry.
In this post, I’ve asked Peter Sprygada and Eric McLeroy five questions about network automation.
Peter Sprygada is a Senior Principal Engineer at Ansible by Red Hat where he brings over 20 years experience building and operating global network infrastructures. He holds two patents in network configuration automation and currently leads the Ansible network engineering team that focuses on building and integrating network automation capabilities into Ansible. Formerly Peter was responsible for building and leading the Arista EOS+ Extensibility Engineering team where he focused on applying DevOps methodologies to enhancing network operations. Prior to that, he held senior network engineering and operations roles at various organizations including Cisco. You can follow him on twitter at @privateip.
Eric McLeroy is a Senior Solutions Architect for Ansible by Red Hat focused on networking use cases. Eric has over 10 years in networking in large scale environments working with a large variety of systems from routers, switches, load balancers, etc. He holds multiple industry certifications and Continue reading

Artificial Intelligence has the potential to bring immense opportunities, but it also poses challenges.
Artificial intelligence (AI) is dominating the R&D agenda of the leading Internet industry. The Silicon Valley and other startup hubs are buzzing about artificial intelligence and the issue has come at the top of policymakers’ agenda including the G20, the ITU, and the OECD, where leaders gathered this week in Paris.
The peak attack size increased 60 percent year-over-year.

About a dozen partners have already committed to integrating Greengrass into their platforms.
The 40 hour work week is foremost a result of the physical limits of the human body—but we often fail to take into account the mental limits, as well. Why was working for more than 40 hours a week on a railroad dangerous? It was not just because people were physically tired, but also because they were mentally tired. The resulting discussion among coders has been rampant and widespread (see, for instance, here).
First, the focus on time and the length of the work week may be a little misdirected. We are still a world focused on physical presence as a proxy for accomplishing work. I know a lot of companies prefer to have people in the office—ironically, this is a big deal with most of the companies in the world that aim to bring networks, and network based services, to the masses.
