Introducing cloudXchange 2018 -  a free series of technical sessions!

Sessions from Uber to Netflix technologists and more:

Presented by:  Amanda Hendley of the Computer Management Group

If there is one constant in our collective business lives, it is that the proverbial cloud has come to represent the majority of IT processes for all of us. The cloud, after all, now accounts for seemingly everything, from our personal lives and how we interact with each other socially, to how we manage our finances, travel, shop, and so on. More importantly, the cloud represents the infrastructure where all of that personal interaction resides.

It’s no surprise that the cloud has digitally transformed our world. But the question becomes, how do we leverage that digital transformation in ways that we have never thought of before? It is for this reason that CMG presents cloudXchange, a way for experts of all types to come together to share best practices—as well as the good, the bad, and the ugly—to mitigate simple risks, such as not making the same mistake twice.

This year sessions, in this free technical event -  will include  - topics like –

  • public and private cloud
  • performance & capacity
  • hybrid systems
  • infrastructure
  • security
  • ML and AI

Specific presentation examples –

  • “Anomaly Detection in Time Series",
  • "Open Source APM Tools - An Overview of Tools and Standards",
  • "Performance Monitoring in Cloud Native Computing: Overcoming Challenges of Traceability in Microservices-based Applications",
  • "Blockchain Performance Engineering"
  • “Exposing the Cost of Performance Hidden in the Cloud"
  • "Continuous Load Testing using Real Browsers from the Cloud"
  • "Measuring Client Performance and Inventing Teleportation
  • "Embedded Analytics for Devices, Edges, and Servers" and many more…

IP Subnet Wireshark Display Filter (by Tony Fortunato)

When asked for advice on how to be a proficient protocol analyst, I give 2 pieces of advice;

  1. Practice looking for patterns. In most cases, you are looking for patterns, or a break in the pattern.  Don’t worry about memorizing the RFC’s or learning about every protocol. It is easier to focus on whatever protocol you are working on at that time.
  2. Learn your display filters in whatever your protocol analyzer you use. The correct display filter will make the patterns jump out at you.

I caution analysts about going capture filter crazy. Unless you know exactly what you are capturing, I typically try to leave the capture filter as ‘open’ as possible. My concern when troubleshooting is that due to the very nature of the unknowns when troubleshooting, you may inadvertently filter out valuable packets.

I great example is you may decide to use a capture filter for a web server ip address when capturing from the client. In this scenario you would miss any packets from the router or other devices along the way if they send the client an ICMP error packet or if the client communicates with other servers.

In this example, I show you that the ip.addr display filter can be used for a subnet.  You are probably familiar with this filter when filtering on a single device. What do you do if you need to filter on more than one host? The typical approach is to combine the ip.addr filter with an or. For example ip.addr==192.168.1.1 or ip.addr== 192.168.1.2 is one way to capture from two hosts.

Don’t Wait for Standards Before Moving Closer to Smart Manufacturing (by Rana Tarakji)

Dont Wait for Standards Before Moving Closer to Smart Manufacturing

Smart Manufacturing has been making a lot of noise in the manufacturing industry, mostly due to how automation can greatly improve manufacturing operations through enhanced productivity. Also known as the “New Industrial Revolution”, this may indeed drastically shift the entire world of manufacturing.

So, what is it?

According to Smart Manufacturing Leadership Coalition, Smart Manufacturing is defined as “integrating network-based data and information that comprises the real-time understanding, reasoning, planning, and management of all aspects of a manufacturing and supply chain enterprise.” Some refer to smart manufacturing as the digitization of various processes in a manufacturing company.

A company that has moved forward to smart manufacturing utilizes intelligent machines, networks, and systems to handle and manage different processes in their operation. Smart manufacturing is basically a term highlighting the different technologies used in manufacturing to make the processes more efficient and more effective.

LMTV LIVE | Improving Packet Analysis with Synthetic Testing (with Steve Brown and Ward Cobleigh)

LIVE EVENT START TIME : Wednesday, May 16th, 2018 9:30 AM PST

AlterEgoQuiz_LMT200Whether troubleshooting basic user complaints or trying to determine performance in the cloud, the challenges are the same in determining:

  • Where to begin troubleshooting?
  • Is it the network, application, client, server, or now cloud?

We’ll join with experts from Viavi product manager Ward Cobleigh and solutions director Steve Brown to discuss how to use synthetic testing to improve troubleshooting with packet analysis. In this edition of LMTV, we’ll focus on:

  • Extending visibility to the network edge, public cloud, and remote users
  • Confirming issue domain gets to root cause faster

We’ll also run through Viavi’s newest cloud NPM service ObserverLIVE showing troubleshooting examples for the public cloud, distributed architectures, and constant network firefighting scenarios. In the meantime, you can learn about free trials of the service at: www.ObserverLIVE.com


Cloud Networking – Once More Into The Breach (by Keith Bromley)

Cloud Networking – Once More Into The Breach

Anyone who has been in networking for several years has seen an exorbitant amount of change. Initially, businesses had physical (racks and chassis) network and switching equipment that resided on their physical premises. This was their corporate network consisting of routers, switches, servers, etc. The simple network concept expanded to include wide area networking, international and distributed offices, and then extensive security measures including IPS, IDS, DLP, WAF, etc.

The concept took a quantum leap as we went through a “virtualization” mania a few years ago. Everything needed to be moved to virtualized servers located in the virtual data center. Now we are on the precipice of another quantum leap, the use of cloud networking, where a significant majority of capabilities are being moved to either public or private cloud networks.

Scary

Whether you are a proponent of this move to the cloud or not, there are some things to consider if, and when, you decide to take the plunge. While there has been a lot of hype around the benefits of cloud computing, very little is being said about the inherent drawbacks.
