General – My Packing List for CLUS and Advice for International First Timers

It’s almost time for Cisco Live in Las Vegas. It’s Friday morning here and I have 95% of the packing done and I leave on Saturday. If this is your first time going to CLUS or even going to the US it can be challenging to know what to pack and if you need to bring cash etc. Here are some of my recommendations for packing. Make a list so that you don’t forget to pack things.

Essentials

Make sure to pack your passport. This is pretty obvious. Hopefully you already made sure that the passport is up to date as well.

I bring a copy of my approved ESTA. This is not mandatory but it’s nice having it there in case a security officer asks you. Depending where you are from you might not be part of the ESTA program.

I always print a copy of my booking for the flight and hotel etc. While not something you need when you have electronic check-in etc. I still like to keep a copy so that I have all of the info about my flight and hotel in case I can’t get on my phone.

Electronic Devices

Bring a power bank. Continue reading

Getting Started: Installing a Tower Cluster

In this Getting Started blog post, we cover how to install Ansible Tower by Red Hat as a clustered environment. If you haven’t already, check out our previous post that outlines the steps on how to install Tower on a single node.

What’s Different with Clusters?

With the addition of Clustering with Tower 3.1, Tower users now have the ability to install Tower as a clustered install rather than just doing an all-in-one install. Clustering is sharing load between hosts. Each node should be able to act as an entry point for UI and API access. This should enable Tower administrators to use load balancers in front of as many nodes as they wish and maintain good data visibility.

Installing Tower in a cluster only has two differences from a standard all-in-one Tower install:

• A separate physical or virtual machine to house an external database
• A different method of editing your inventory file

If you are preparing to install Tower, consider what function Tower will serve for you. If you are deploying Tower in a production environment, you should be using a clustered installation able to provide highly available Tower instances and use an external DB, either as a Continue reading

Trend: Colocation facilities provide tools to manage data center infrastructure

Enterprises understand the advantages of colocation, but they also know that entrusting mission-critical infrastructure to third-party data centers means giving up some control over their servers.Data center Infrastructure Management (DCIM) tools can provide colocation customers with transparency into their data center's operations, to verify that providers are fulfilling the terms of their Service Level Agreements. A DCIM platform gives customers a "single pane of glass" to view the status of their IT infrastructure."Today, more colocation providers are offering their customers access to DCIM portals," explains Rhonda Ascierto, Research Director for Data centers and Critical Infrastructure at 451 Research. "Customers want to see how well a colocation facility is operating, not just rely on the SLA. A DCIM tool gives the customer visibility into data center operations, and assurance that the colocation provider is meeting their obligations."To read this article in full or to leave a comment, please click here

6 things you need to know about virtual private networks

A virtual private network is a secure tunnel between two or more computers on the internet, allowing them to access each other as if on a local network. In the past, VPNs were mainly used by companies to securely link remote branches together or connect roaming employees to the office network, but today they're an important service for consumers too, protecting them from attacks when they connect to public wireless networks. Given their importance, here's what you need to know about VPNs:VPNs are good for your privacy and securityOpen wireless networks pose a serious risk to users, because attackers sitting on the same networks can use various techniques to sniff web traffic and even hijack accounts on websites that don't use the HTTPS security protocol. In addition, some Wi-Fi network operators intentionally inject ads into web traffic, and these could lead to unwanted tracking.To read this article in full or to leave a comment, please click here

Worth Reading: Token Effects

Tokens are a new business model that’s emerging for open source. It’s a new way to raise capital by selling tokens through an ICO (initial coin offering). If the project succeeds, its token will appreciate in value, giving early adopters a nice return. … The token is a cryptocurrency that is used to both improve the product and compensate all participants in the network. —Free Code Camp

Casing The HPC Market Is Hard, And Getting Harder

Markets are always changing. Sometimes information technology is replaced by a new thing, and sometimes it morphs from one thing to another so gradually that is just becomes computing or networking or storage as we know it. For instance, in the broadest sense, all infrastructure will be cloudy, even if it is bare metal machines or those using containers or heavier server virtualization. In a similar way, in the future all high performance computing may largely be a kind of artificial intelligence, bearing little resemblance to the crunch-heavy simulations we are used to.

It has taken two decades for cloud …

Subscription Defined Networking

Cisco’s big announcement this week ahead of Cisco Live was their new Intent-based Networking push. This new portfolio does include new switching platforms in the guise of the Catalyst 9000 series, but the majority of the innovation is coming in the software layer. Articles released so far tout the ability of the network to sense context, provide additional security based on advanced heuristics, and more. But the one thing that seems to be getting little publicity is the way you’re going to be paying for software going forward.

The Bottom Line

Cisco licensing has always been an all-or-nothing affair for the most part. You buy a switch and you have two options – basic L2 switching or everything the switch supports. Routers are similar. Through the early 15.x releases, Cisco routers could be loaded with an advanced image that ran every service imaginable. Those early 15.x releases gave us some attempts at role-based licensing for packet, voice, and security device routers. However, those efforts were rolled back due to customer response.

Shockingly, voice licensing has been the most progressive part of Cisco’s licensing model for a while now. CallManager 4.x didn’t even bother. Hook things up and Continue reading
