IDG Contributor Network: Should IT operations be event-driven or data-driven?

An overview of events The essence of IT Operations Management for the last 30 years (ever since the advent of distributed systems in the mid 1980’s) has been to understand what is “normal” and what is “abnormal” and to then alert on the anomalies. Events are anomalies.Now events come from an incredible variety of sources. Every element of the entire stack (disks, storage arrays, network devices, servers, load balancers, firewalls, systems software, middleware and services and applications) are capable of sending events.Events tend to come in two broad forms. Hard faults and alarms related to failures in the environment (this disk drive has failed, this port on this switch has failed, this database server is down), and alerts that come from violations of thresholds set by humans on various monitoring systems.To read this article in full or to leave a comment, please click here

Study: Apps move rapidly to the cloud, data not so much

While the public cloud continues to grow at the expense of on-premises data centers, not everything that moves to the cloud stays there. Some data comes back, for a variety of reasons. And while apps are moving to the cloud at a rapid clip, data is not.That’s the findings of a recent report by 451 Research commissioned by Schneider Electric, entitled “Customer Insight: Future-Proofing Your Colocation Business.” It finds, for example, that global operational square footage hosting cloud infrastructure will grow at a 16 percent compound annual growth rate (CAGR) from 2017 to 2020, while the amount of on-premises enterprise data center capacity will drop four percentage points, from 77 to 73 percent in the same time period.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Behold the secure directional network connectivity of SuperWAN

Imagine you are Clark Kent, CIO of a large organization in Metropolis, and current trends in network disaggregation continue. As such, you must now provide connectivity to three Azure data centers for Office 365; 20 AWS sites located all over the world for a host of outsourced IT applications; four corporate data centers (older applications); 10 Equinix data centers for outsourced private use; direct access to 25 additional cloud service offerings for security reasons, including UC services, Salesforce.com and Concur, to your 500 branch sites; and 30,000 telecommuting employees.Look up in the sky! It’s a WAN! No, it’s a SD-WAN! No, it’s... SuperWAN!To read this article in full or to leave a comment, please click here

Lab Requirements for Ansible for Networking Engineers Online Course

One of the undergraduate students attending my Ansible for Networking Engineers online course got to the point where he wanted to start hands-on work and sent me a list of questions:

Do I have to buy a VIRL license to use your Ansible course materials? Or is VIRL in any Github repository? Is there a way to use your files in a free Tool like GNS3?

Let’s go through them one by one:

IPv6, Routing Security, and More Coming to ION Belgrade

We’re getting pretty close to ION Belgrade on Thursday, 23 November. This ION will be held alongside the Republic of Serbia Network Operators’ Group (RSNOG). As usual, this ION also has generous support from our ION Conference Series Sponsor Afilias.

This time, we’re doing a half-day program focusing mostly on IPv6, Routing Security and MANRS, and the IETF. Here’s a quick look at the agenda:

  • Opening Remarks
  • Welcome from the ISOC Serbia Chapter
  • MANRS, Routing Security, and Collaboration
  • NAT64check
  • What’s Happening at the IETF? Internet Standards and How to Get Involved
  • Panel Discussion: IPv6 Success Stories
  • Closing Remarks

Registration will open two weeks before the event (around 10 November) – watch here for announcements! RSNOG is also planning to livestream the whole event, so even if you can’t be there in person you’ll be able to follow along online. Stay tuned for more information on that in the coming weeks.

Will you be in Belgrade or watching online? Please speak up in the comments below or via our social media channels. Also feel free to follow along using #IONConf!

We hope to see you there, or at another event in the future!

Frack You Nvidia

Why ? I am currently using Ubuntu 1604 as the OS on my laptop. It generally works well apart from one thing ... The FRACKING NVIDIA DRIVERS. Nvidia you can go and die in a pit fire. At least 3 or 4 times in the last 6 months the driver update has stopped the system from booting. It gets to a...

Extending Ansible action plugins for Cisco IOS

It started out as a question. If you are using several networking modules in a playbook, do you really have to repeat the same credentials on every task? Just like the last few articles about Ansible this one came to life after answering questions in a chat room. The short answer is; No you don’t have to include all of the required parameters for every task, you can use an action plugin to work around that.

Great! So what’s an action plugin? Continue reading

RIPE 75

RIPE held its 75th meeting in Dubai in mid-October. As usual there was a diverse set of presentations covering a broad range of activities that are taking place on today’s Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centres, IPv6, the DNS, routing and network measurement. If that's not enough, the topic of the Internet of Things has been added as a Working Group in the RIPE pantheon. If you add address policy, database and RIPE services to the mix you get a pretty packed five days with topics that would appeal to most Internet folk

Extreme Transition At Last

It is now almost 12 months since the first announcement that Broadcom was to acquire Brocade, and sell off the IP parts of the business. It took another 6 months to get confirmation that Extreme Networks would be buying my business unit (SRA).

For regulatory reasons, the Broadcom/Brocade transaction has still not closed. The original plan was to close that deal first, then close the Extreme transaction. But due to the delays, they re-arranged things, and now the Extreme deal has finally closed. Desks have been cleared, moving crews are working all weekend, and come Monday, I will have a new “Extreme Networks” badge.

What does this mean for me? My group is moving to become part of Extreme Networks. In the short term, I keep working with the same core group of people. But now we will be part of a new wider group, with a different strategic focus.

We will have new systems and applications to integrate StackStorm with, new use-cases, and maybe further opportunities beyond StackStorm. So far all signs are pointing to this being a positive move, and I am looking forward to getting this transition behind us.

Cisco PIX Security Appliances Firewall modes

Today I am going to talk about the different modes of Cisco PIX firewall. By default if you talk about the mode of the firewall, a firewall is a routed hop and acts as a default gateway for hosts that connect to one of its screened subnets. 

In recent years, a growing best practice has been to deploy firewalls not only at the traditional network perimeter-where the private corporate network meets the public Internet-but also throughout the enterprise network in key internal locations, as well as at the WAN edge of branch office networks. This distributed-firewall strategy helps protect against internal threats, which have historically accounted for a large percentage of cyber losses, according to annual studies conducted by the Computer Security Institute (CSI).

Now let's talk about the different firewall modes. There are two modes of firewalls and they are as routed mode and transparent mode.

Cisco PIX Security Appliances Routed mode
Default mode of an ASA. The ASA acts as a single firewall and all interfaces are provisioned to be managed through a single firewall configuration.
