Introduction to Disaster Recovery
Businesses want to choose reliable equipments, components and technologies while designing a network. You may deploy most reliable equipments from your trusted vendor or deploy most mature technologies with carefully do not forget eventually every system fails!
Depends on where is your datacenter located, different disasters may happen. For U.S storm, tornado is not uncommon. I remember just couple years before because of major flooding, Vodafone couldn’t serve to their customer in Turkey for at least 1 day.
Thus, resiliency is an important aspect of the design plan.Resiliency means, how fast you can react to failure with the simplest explanation.
Disaster recovery is the response and remediation that a company follows after a planned or unplanned failure. Businesses often have a secondary datacenter used mostly for backup. If the company has multiple datacenter, they can be used as active/active though.
Secondary datacenter can take the responsibility in the case of a primary datacenter fails if it is used as backup.
Recovery time will depend on business requirements.For the mission critical applications, business may tolerate very short if not zero down time. Then the cost of the required equipments in primary and backup datacenters, skilled engineer who can Continue reading
4 people passed CCDE Lab with my CCDE training recently!
I realised just now that I didn’t share the names of the people who used my CCDE resources and got their CCDE numbers recently.
I know all of them, their capabilities, technical strength. I am happy to see that they are CCDE now.
Congrats to Ken Young , Jaroslaw Dobkowski , Malcolm Booden , Bryan Bartik.
Some of them used Self Paced CCDE Course , Some joined Instructor Led CCDE Training as well. I am honoured to hear good feedbacks from all and share their feedbacks in the related pages on the website.
In 2017, around 10 people passed the CCDE Lab exam with these people. And there was one cancelled exam on May 2017.
CCIE vs. CCDE
CCIE vs. CCDE is probably one of the most frequently asked questions by networking experts.
To get more information on CCDE contents and syllabus, you can check my Instructor Led CCDE or Self Paced CCDE course webpages.
How many times have you asked yourself or discussed this topic with your friends? Many times, right?
I have CCIE routing switching and/or service provider, should I continue to design certificates such as CCDE or should I study for another expert level certification, perhaps virtualization certification?
To illustrate my answer, let me give you an example.
Consider that you would build Greenfield network. (Usually, it is the same for Brownfield as well).
First, you need to understand the business, how many locations it has, where it is located, where is HQ or HQs, Datacenter, POP locations, and so on.
After that, you try to understand how the business can assist its consumers.
It can be retail, airport, stadium, or service provider network.
All these businesses have similar and different requirements,
For example, stadium architecture requires you to have ticketing systems, access control systems, and streaming the game, all of which are connected to the network. So, you need to understand the business requirements, Continue reading
VRF-Lite+GRE/dot1q or MPLS L3 VPN
I am going to create a new category on the blog which we will discuss together the different technologies,protocols, designs and architecture.
You can suggest a discussion topics and you all please welcome to join the discussions in the comment box of each topic.
I want to throw a first topic for the discussions !
Which Enterprise Architecture is more complex ? ( Did you read network complexity article in the blog ? )
MPLS VPN Technologies and Design are explained in detail in my Instructor Led CCDE and Self Paced CCDE course.
VRF-lite with GRE/dot1q or MPLS L3VPN ?
It is very subjective topic I think there is not absolute corrects thus please share your opinion.Collective of our answers will be creating a detail article and will provide a good resource for the people before they decide a particular technology,protocol,architecture.
UPDATE : Let me provide very brief overview for vrf-lite and MPLS VPNs.
How they can be carried through an overlay to provide data plane separation and how same tasks can be achieved with MPLS layer 3 VPNs.
Vrf-lite provides a control and data plane separation without requiring an MPLS as control or data plane. You don’t need an MPLS Continue reading

The Internet Society & Public Interest Registry: A New Era of Opportunity
Today marks the beginning of an exciting new chapter for the .ORG Community. Earlier today, the Internet Society and Public Interest Registry (PIR) announced that they have reached an agreement with Ethos Capital, an investment firm that helps transform and grow companies in today’s rapidly evolving digital economy, under which Ethos Capital will acquire PIR and all of its assets from the Internet Society.
As brief background – in 2002, the Internet Society won a competitive bidding process for the .ORG registry and established PIR to manage and operate the .ORG domain. Since that time, the Internet Society and PIR have worked to grow .ORG into the largest purpose-driven domain – used today by millions of organizations and others to achieve their online goals – and PIR’s contributions to the Internet Society have helped make the Internet more available, accessible and secure for people around the world.
This transaction aligns PIR with a strong, new strategic partner, Ethos Capital, that not only possesses a deep understanding of the intricacies of the domain industry, but also has the ideal mix of expertise, experience and shared values to further advance the goals of .ORG into the future.
