PitchBook moves to a microservices infrastructure – scaling the business through scalable tech

PitchBook is a data company. Its reason for being is to provide a platform that tracks a plethora of different aspects of both private and public markets. Want to know about what’s happening in venture capital, private equity or M&A? Chances are PitchBook can give you the answer. The company is a subsidiary of Morningstar and has offices in Seattle, New York, and London.But here’s the thing, though. PitchBook was founded in 2007 when cloud computing was pretty much just beginning and there was no real awareness of what it meant. In those days, enterprise IT agility meant leveraging virtualization to gain efficiencies. Now don’t get me wrong, moving from a paradigm of racking and stacking physical servers to being able to spin up virtual servers at will is a big deal, it’s just that since 2007, there has been massive further innovation in the infrastructure space.To read this article in full or to leave a comment, please click here

Juniper’s Cloud-Grade networking aims to deliver network agility

There should be no question in anyone’s mind that the cloud era has arrived. Businesses are adopting the cloud at an unprecedented rate and by 2020, the number of cloud workloads will be on par with the number of on-premises ones.Businesses of all sizes are turning to the cloud to help them become digital by increasing the level of agility. To be an agile business, though, the entire network stack—from the network through applications must be agile.+ Also on Network World: Juniper heads to the clouds with Unite + However, organizations are also more cost conscious than ever, so whatever solution is deployed must save money in addition to making the network more dynamic. To read this article in full or to leave a comment, please click here

Worth Reading: A lesson on cloud agility

As first reported by CNBC on Wednesday, retail and e-commerce giant Wal-Mart notified some of its technology partners that they need to move their information assets away from Amazon Web Services if they want to continue doing business. This move certainly comes as no surprise to many, as the two companies are long-standing rivals in their respective quests to dominate the world of retail. It comes just days after the company’s CEO, Doug McMillon, told his company’s annual associates’ meeting, “Looking ahead, we will compete with technology, but win with people. We will be people-led and tech-empowered.” —The New Stack

Time to consider a move to IPv6

Organizations should consider migrating their network infrastructure and devices over to IPv6. It may be a challenge to persuade leadership to prioritize it over other projects such as cloud computing or big data migrations, but it is essential to start planning for a migration.Many service providers, such as Comcast, Verizon and AT&T, have already started using IPv6 addresses and are presently encouraging other organizations across the United States to do the same. The Internet Engineering Task Force (IETF) has encouraged organizations to move forward with these migrations for over a decade, and with more devices connecting to the internet, the need has increased. To read this article in full or to leave a comment, please click here

Cisco and Juniper Routers : OSPF point to multipoint configurations

Today I am going to discuss on the OSPF configuration part, As you already know about the OSPF protocol and the network types in OSPF.

OSPF is a link state routing protocol and i wrote some of the articles on OSPF earlier as well. Please go through that articles to understand more about OSPF protocol

OSPF Basics
OSPF States
OSPF vs RIP protocols
Routing Basics : Distance Vector vs Link State Routing Protocol

Above are some of the articles on OSPF will help you more in the interview preparation.

OSPF Point to Multipoint Networks
In the point-to-multipoint configurations, we need to emulate broadcast capability, it seeks to organise the PVCs into a collection of point-to-point networks. In the case of OSPF point to multipoint networks, the hello packets must still be replicated and transmitted individually to each neighbor, but the multipoint approach offers two distinct advantages: no DR/BDR is needed, and the emulated point-to-point links can occupy a common subnet.

Apart from all these today I am going to have sample configurations on OSPF point to multipoint networks.

Here in this article I am going to take a topology of OSPF point to multipoint network and let you know the Continue reading

Even weak hackers can pull off a password reset MitM attack via account registration

At the IEEE Symposium on Security and Privacy 2017, researchers from the College of Management Academic Studies in Israel presented an interesting paper on bad password reset processes, “The Password Reset MitM Attack” (pdf). It explains how a weak attacker could take over accounts by exploiting vulnerabilities in password reset procedures.They dubbed the attack: password reset man-in-the-middle (PRMitM). The researchers said Google is “extremely vulnerable” to PRMitM, but Facebook, Yahoo, LinkedIn, Yandex and other sites and email services are also vulnerable as well as mobile apps like Whatsapp, Snapchat and Telegram.To read this article in full or to leave a comment, please click here

“Focusing on the Gift” (aka How Fish views Presenting)

CiscoLive starts today and so do my presentations.  If you have ever wondered what I’m thinking about right prior to a presentation…. I am imagining a small and beautifully wrapped gift that I want to give to each and every person in the audience. That is what I am doing.  I am “Focusing on the Gift”.

Have I always done that?  LOL.  Uh… no.  But fortunately I don’t think my 2006 Networkers presentation on EIGRP is available on video.   Otherwise I think I’d be truly embarrassed.  Why?  Because it was my first Networkers/CiscoLive presentation and I was beyond belief nervous.  Worried if I’d do okay… worried if you were enjoying the session… oh the list goes on and on as to everything I was thinking and worried about.

And then I realized something.  You know what? It really isn’t about me at all.  I am just a vehicle.  It is all about “The Gift”.  So in 2007 I went out and bought a tiny little Christmas tree sized ornament of a perfectly wrapped gift box.  Small enough that I could hide it up on the stage Continue reading
