Fighting the Ecosystem Wars in the Proactive Cloud

This article is a chapter from my book Explain the Cloud Like I'm 10. It has 30 reviews on Amazon! If you like this chapter then you'll love the book.

 

 

The cloud is always busy proactively working for you in the background. That’s how cloud services compete with each other to keep you in their ecosystem.

 

Most of the cloud services we’ve talked about so far have been request driven. You initiate a request and the cloud does something for you. You read a book. You search for the nearest coffee shop. You navigate to a destination. You send a message. You play a movie.

Handling direct requests is not all a cloud is good for. In fact, the biggest potential of the cloud is how it can proactively perform jobs for you in the background, without you asking or even knowing that it can be done.

Let’s set this up:

Itential puts organizations on the path to the modern network

In the realm of enterprise computing, we have already automated the management and orchestration of software-defined compute and storage resources. Need another server or more storage capacity? Those virtual resources can be created in mere minutes — and without intervention from a human to initiate or manage the process.Need changes to the network, such as a router reconfiguration? Well, that’s going to take a lot of time and effort from a range of humans. Even something as simple as an update to a DNS or IPAM server can take three to five days to complete. A port turn-up can take just as long — not because any physical action takes that much time, but because the workflow of all the human reviews and approvals takes time.To read this article in full, please click here

Presenting To The D-Suite

Do you present to an audience? Odds are good that most of us have had to do it more than once in our life or career. Some of us do it rather often. And there’s no shortage of advice out there about how to present to an audience. A lot of it is aimed at people that are trying to speak to a general audience. Still more of it is designed as a primer on how to speak to executives, often from a sales pitch perspective. But, how do you present to the people that get stuff done? Instead of honing your skills for the C-Suite, let’s look at what it takes to present to the D-Suite.

1. No Problemo

If you’ve listened to a presentation aimed at execs any time recently, such as on Shark Tank or Dragon’s Den, you know all about The Problem. It’s a required part of every introduction. You need to present a huge problem that needs to be solved. You need to discuss why this problem is so important. Once you’ve got every head nodding, that’s when you jump in with your solution. You highlight why you are the only person that can do Continue reading

How to make the business case for SD-WAN

Entegra Bank, a fast-growing financial institution based in the Blue Ridge Mountains of North Carolina, switched from MPLS links for its 22 branches to SD-WAN-based broadband and slashed its WAN connectivity bill by 50%, while increasing bandwidth an average of fivefold.Loren Long, senior vice-president and CTO at the bank, says he had been eyeing both SD-WAN and broadband for some time, waiting for SD-WAN technology to mature and for rural broadband to improve in availability, dependability and security. After a positive experience with Silver Peak’s WAN optimization gear, “we felt confident to make that change,” he says.In a typical SD-WAN scenario, branch office broadband would connect directly to the public Internet. But since this a bank with heightened security and compliance responsibilities, traffic from the branches is backhauled over an encrypted VPN to internal gateways, where a third-party security services provider monitors all traffic and enforces security policies.To read this article in full, please click here

Using MPLS+EVPN in Data Center Fabrics

Here’s a question I got from someone attending the Building Next-Generation Data Center online course:

Cisco NCS5000 is positioned as a building block for a data center MPLS fabric – a leaf-and-spine fabric with MPLS and EVPN control plane. This raised a question regarding MPLS vs VXLAN: why would one choose to build an MPLS-based fabric instead of a VXLAN-based one assuming hardware costs are similar?

There’s a fundamental difference between MPLS- and VXLAN-based transport: the amount of coupling between edge and core devices.

ASAP: fast, approximate graph pattern mining at scale

ASAP: fast, approximate graph pattern mining at scale Iyer et al., OSDI’18

I have a real soft spot for approximate computations. In general, we waste a lot of resources on overly accurate analyses when understanding the trends and / or the neighbourhood is quite good enough (do you really need to know it’s 78.763895% vs 78 ± 1%?). You can always drill in with more accuracy if the approximate results hint at something interesting or unexpected.

Approximate analytics is an area that has gathered attention in big data analytics, where the goal is to let the user trade-off accuracy for much faster results.

(See e.g. ApproxHadoop which we covered on The Morning Paper a while back).

In the realm of graph processing, graph pattern mining algorithms, which discover structural patterns in a graph, can reveal very interesting things in our data but struggle to scale to larger graphs. This is in contrast to graph analysis algorithms such as PageRank which typically compute properties of a graph using neighbourhood information.

Today, a deluge of graph processing frameworks exist, both in academia and open-source… a vast majority of the existing graph processing frameworks however have focused on graph Continue reading

Fun in the Lab: FTDv & FMC – Install and Deploy

This is my Stealthwatch playground…. errrr… I mean … ahem… “work environment” for a Technical Solution Workshop I am working on for Stealthwatch.

Going to set up FTDv and FMC today.  A co-worker and friend, Scott Barasch, helped me get jump started… so figure I’ll pass on what I just learned to you. ?

What this blog will cover is

  1. DEPLOY
    1. Deploying the OVF for FTDv
    2. Deploying the OVF for FMC
  2. VMware settings
    1. Tweak for FTDv
    2. Tweak for FMC
  3. Prepping to Power On
    1. Snapshot Both Before Power On
    2. Power Both On
  4. Setup via Console
    1. FMC – console in and setup IP address
    2. FTDv – console in and step thru the prompts
  5. Test IP Connectivity
    1. Ping FMC and FTDv from the PC
    2. Notice Can’t ping FTDv
    3. Fix
    4. Ping
  6. Browse into FMC
    1. Change password
    2. Setup DNS
    3. Setup NTP
    4. Accept EULA
    5. Apply
  7. LICENSING
    1. License FMC
  8. FMC/FTDv: Make the Connection
    1. FTDv – Point FTDv to FMC
    2. FMC – bring the FTDv into the fold.  ?

 

So let’s begin.  What I have to host my FMC & FTDv VMs is a UCS M4 with a NIC connected to a Cat4948 in vlan 1.  That NIC is tied to vSwitch0 in the UCS. Continue reading

Use Cumulus HTTP API to Help Automate Common Network Tasks

Cumulus Linux includes a RESTful programming interface for accessing network devices running that OS. It’s called HTTP API, and it implements an API to access the OpenStack ML2 driver and Network Command Line Utility, or NCLU. Understanding exactly what this means, and how it works, is essential before digging into the possibilities it presents. Here’s an overview to get this going.

The OpenStack ML2 Driver

The ML2 Driver, a.k.a. (in OpenStack’s terms) the Modular Layer 2 neutron plug-in, provides a framework. It enables OpenStack-based networking to use a variety of Layer 2 networking technologies, including those from Cumulus (for which a specific ML2 driver is available and ready to use). To use the OpenStack ML2 driver with Cumulus Linux switches, two essential ingredients must be present:

  1. The REST API, which comes installed in Cumulus Linux. This includes an ML2 HTTP Server, which recognizes and responds to such requests. This runs on Cumulus-based network nodes to which management consoles or nodes will attach to interrogate, configure, or otherwise interact underlying devices.
  2.  Elsewhere on the network, the Cumulus ML2 Mechanism Driver should be installed on a VM or system running Cumulus Linux. This is called a “controller node.” Continue reading
